Solar workflow depth
Can the product carry system details, proposal status, project milestones, and the delivery handoff without rebuilding the process in custom fields?
Quickest Solar CRM ranks first under our proposal-first value and adoption lens. This guide discloses that commercial relationship and every unverified Hungarian capability, then compares six alternatives across HUF quotations, VAT, MVM Hálózat and distribution operator workflows, current HMKE connection and settlement assumptions, Hungarian documents, GDPR, Online Számla, buyer-required structured invoices, batteries, installation, commissioning, metering, and handover.
Direct answer
Quickest Solar CRM is our first proposal-first trial for a Hungarian solar team. QuickEstimate publishes this ranking and sells Quickest. HUF quotations, Hungarian VAT, Online Számla, buyer-required structured invoices, MVM Hálózat and distribution operator workflows, current HMKE connection and settlement terms, legacy settlement records, responsible electrical professional evidence, Hungarian documents, GDPR processor and transfer terms, Hungary support, local payments, accounting, integrations, batteries, installation, testing, commissioning, metering, and handover are all unverified for Quickest.
7 jobs, 7 picks
A useful shortlist starts with the sales or delivery bottleneck. Each winner below reflects a different buying priority, while the overall ranking rewards a CRM that a solar sales team can adopt quickly.

We saved four English and Hungarian searches across Google, Bing, DuckDuckGo, and Brave. Google returned redirect shells, DuckDuckGo challenges, Brave rate limits, and Bing unrelated or noisy results, so we do not invent organic positions or People Also Ask questions. The bounded Grok stage returned no completed X evidence report. We assessed vendors against MVM Hálózat, NAV, the European Commission, NAIH, and the national consumer-protection authority.
Can the product carry system details, proposal status, project milestones, and the delivery handoff without rebuilding the process in custom fields?
Can managers route leads, track activity, automate follow-up, forecast revenue, and see why an opportunity stalled?
Can a rep move from site information to a credible customer proposal, and how much specialist solar design happens inside the platform?
Does the workflow support the language, currency, tax, communications, documents, and handoffs common in Hungary?
What setup, migration, training, administration, and extra software does the apparent subscription require?

Country research
The test is whether accepted sales data survives design, the correct distribution-operator route, HMKE review, installation, testing, commissioning, meter and settlement handoffs, invoice reporting, and customer handover. One generic approval stage cannot represent those responsibilities.
MVM Hálózat defines a household-size small power plant, or HMKE, as low-voltage generation with connection capacity no higher than 50 kVA at one connection point. Its live page includes connection-point, inverter, feed-in restriction, data-reporting, storage-programme, and settlement information. Treat MVM as one distribution territory and follow the actual site's licensed operator. Store address, POD or meter identifiers, phase, available power, requested capacity, inverter, battery, feed-in status, and checked route.
MVM Hálózat: Household-size small power plants ↗MVM Hálózat publishes a separate small-power-plant area outside the household HMKE page. Residential, commercial, larger, storage, and changed-capacity cases should not share one automatic route. Preserve the classification decision, responsible designer and contractor, network request, technical documents, studies where required, connection offer and agreement, costs, deadlines, equipment, protection settings, tests, commissioning, metering, and later changes.
MVM Hálózat: Small power plants ↗HMKE settlement depends on commissioning date, eligibility, supplier relationship, meter data, and the current contractual regime. The live MVM page contains separate material on annual-balance and gross settlement questions, feed-in restrictions, and removal of restrictions in some areas. A proposal should record the named regime and evidence, import and export prices, period, fees, consumption, production, self-use, battery behaviour, checked date, and sensitivity rather than promising one national return.
MVM Hálózat: Household-size small power plants ↗NAV maintains Hungary's VAT information. A solar job can combine panels, inverters, installation, batteries, design, maintenance, repairs, monitoring, finance, and building work whose treatment depends on the facts and current law. Configure tax per line and effective date, then have a Hungarian adviser approve rates, deposits, milestones, corrections, credit notes, cross-border purchases, invoice wording, and reporting.
National Tax and Customs Administration: Value added tax ↗NAV operates Online Számla for invoice-data reporting. A PDF or quotation is not proof of a complete report. Test the taxpayer and customer identifiers, invoice data, technical user and credentials, API or accounting handoff, validation, returned status and errors, modification and cancellation documents, credit notes, permissions, retention, reconciliation, monitoring, retries, and complete export in the purchased implementation.
National Tax and Customs Administration: Online Invoice ↗The European Commission's Hungary page describes the structured public-sector eInvoicing environment alongside invoice-data reporting. Requirements and formats are time-sensitive. Test the exact B2G or customer-required structured route, identifiers, EN 16931-compatible data where applicable, transport, validation, delivery response, rejection, correction, attachments, archive, accounting reconciliation, and export. Do not treat Online Számla reporting and invoice delivery as the same workflow.
European Commission: eInvoicing in Hungary ↗A Hungarian solar CRM stores names, addresses, site photographs, electricity use, signatures, finance material, messages, and staff activity. NAIH is the national data-protection authority. Procurement should cover controller and processor roles, Article 28 terms, subprocessors, security, incidents, hosting and support locations, transfers, retention, deletion, access, correction, objection, marketing suppression, and complete export.
National Authority for Data Protection and Freedom of Information: Data protection authority ↗Hungary's national trade and consumer-protection authority oversees business-to-consumer practices. A residential sales record should preserve the advertisement, lead source, channel, quotation, pre-contract information, terms, withdrawal material where applicable, delivery timestamp, signature, any request for early work, deposits, invoices, changes, complaints, and responses. Hungarian counsel should approve the actual process and document versions.

Each review explains the useful workflow, the buyer who should shortlist it, and the country-specific question that a sales demo must answer.
Quickest is our first proposal-first trial only if every Hungarian quotation, grid, tax, privacy, integration, field, and handover gate passes before live use.
Quickest focuses on solar leads, proposals, follow-up, and pipeline visibility. Its public free plan supports a contained adoption test, which is why it ranks first under this guide's declared proposal-first method. That position reflects the method and the publisher's product relationship, not verified Hungarian breadth.
Every local capability remains unverified: HUF quotations; Hungarian VAT; Online Számla; buyer-required structured invoices; MVM Hálózat and distribution operator workflows; current HMKE connection, settlement, and export terms; legacy settlement records; responsible electrical professional evidence; batteries; Hungarian documents; GDPR processor and transfer terms; Hungary support; local payments, accounting, and integrations; installation, testing, commissioning, metering, and handover. The public security page states AWS Mumbai hosting, which also requires a Hungarian privacy and transfer review.
Choose it if: proposal and follow-up adoption is the immediate bottleneck and all Hungarian acceptance gates pass. Choose another platform if: you need evidenced local design, fiscal localisation, or delivery breadth with less verification work.
Arka360 combines solar design and CRM globally, while current Hungarian network and settlement, tax, privacy, and delivery depth still need proof.
Arka360's public product joins AI-assisted 3D design, shading and performance modelling, proposals, CRM, leads, tasks, and project progress. Its public pages describe proposal configuration and residential and commercial use. Hungarian distribution operator, self-consumption and export, responsible electrical professional, VAT, Online Számla, structured-invoice, GDPR, Hungarian-document, WhatsApp, local-accounting, field, commissioning, metering, and handover capabilities remain unverified. Omit its outcome figures unless your evaluation substantiates them.
Choose it if: you want to test a global combination of solar design, proposals, and CRM in this shortlist. Choose another platform if: accounting and ERP operations matter more than specialist solar design, or you need a free core product.
SurgePV is a credible design and electrical candidate, but its unverified Hungarian network and settlement localisation requires a complete proof.
SurgePV joins roof modelling, shading, simulation, electrical documents, financial modelling, and proposals. No checked page verifies HUF output, Hungarian applicable HMKE settlement terms, distribution operator work, or a distribution operator API. Require a complete Hungarian demonstration and reject unsupported outcome claims.
Choose it if: design, electrical documentation, simulation, and proposals are central and current Hungarian network and settlement checks pass. Choose another platform if: you need documented local fiscal support or want less localisation work during evaluation.
OpenSolar is the most accessible design-led option, with every Hungarian grid, tax, privacy, language, and delivery requirement still needing proof.
OpenSolar keeps site data, design, equipment, production assumptions, price, proposals, and internal project workflow together. The core app remains free, while API Access and supported connectors cost extra. Hungarian climate and tariff settings, distribution operator connection, metering, self-consumption and export terms, VAT, Online Számla, structured invoices, Hungarian documents, GDPR, WhatsApp, local support, commissioning, and handover work remain unverified.
Choose it if: free core design and proposals are the priority and the team can define its surrounding Hungarian stack. Choose another platform if: you require verified local invoicing or a current grid workflow with less configuration.
Pylon suits project-priced design evaluation, provided Hungarian assumptions, currency, grid work, privacy, integrations, and delivery evidence pass.
Pylon publishes solar design, interval-data analysis, web and PDF proposals, project tools, API capability, and optional CRM. Its dollar symbol is not clearly HUF pricing. Request Hungary terms and total cost. distribution operator connection, metering, self-consumption and export terms, VAT, Online Számla, structured invoices, GDPR, bilingual output, WhatsApp, commissioning, and handover remain unverified.
Choose it if: you want project-priced design and proposals with the option to add a connected solar CRM. Choose another platform if: you need broader operations in one implementation or fiscal scope that your adviser has already approved.
Zoho is a capable generic CRM and WhatsApp candidate when the installer has clear ownership for solar design, grid, finance, and field configuration.
Zoho CRM covers leads, deals, activities, email, automation, reports, mobile apps, custom fields, and a documented WhatsApp Business connection. It needs connected solar design and configured HUF quotations, network and settlement, technical-study flags, VAT, Online Számla and structured e-invoicing, installation, and handover. Test Meta requirements, templates, opt-in, charges, assignment, attachments, retention, suppression, and export.
Choose it if: your team values a mature configurable CRM and can own the Hungarian solar implementation and integrations. Choose another platform if: you want solar design built in or a system whose Hungarian fiscal scope has already been demonstrated.
Odoo offers broad operational scope, but Hungarian fiscal work, solar design, and current distribution operator delivery all require a complete demonstration.
Odoo's suite spans CRM, sales, projects, field service, inventory, invoicing, accounting, documents, and signatures. We did not find a working current Hungary localisation page during this review. Treat Hungarian VAT, Online Számla, structured invoices, bookkeeping, retention, audit, and export as unverified until a partner demonstrates the purchased setup. Odoo still needs specialist solar design and configured distribution operator, responsible electrical professional, bilingual, WhatsApp, commissioning, metering, and handover work.
Choose it if: broad operational control outweighs the need for native solar design and you can validate the Hungarian implementation. Choose another platform if: you need a focused sales trial, a faster design tool, or a lighter implementation.
Buyer guide
Choose by the most expensive broken handoff, then test that handoff using real opportunities, real users, and the documents your customers actually receive.
Quickest tests adoption of a focused lead, quotation, follow-up, and pipeline tool. OpenSolar tests free core design and proposals. Use the same home project, then prove HUF, network and settlement, VAT, GDPR, bilingual documents, WhatsApp, and handover.
Quickest is the proposal-first adoption candidate. Arka360 is a global design and CRM candidate, but no Hungary-specific page or localisation proof was found. Neither should pass procurement without the complete current Hungarian network and settlement and data test.
Both position design and proposals for larger projects. Test load data, equipment, simulation, drawings, economics, decision-makers, larger-system grid review, revisions, commissioning, and handover. Neither vendor has verified Hungarian grid, export, tax, or handover localisation.
OpenSolar offers a free internal core, while Pylon publishes project prices and an optional CRM. Price API, connectors, accounting, support, and users. Inspect how accepted design data reaches network and settlement administration and field delivery.
Zoho is the generic CRM candidate for teams that value configurable pipelines, automation, mobile work, and documented WhatsApp Business integration. It needs a specialist design layer and deliberate network and settlement, VAT, Online Számla and structured e-invoicing, installation, and handover configuration.
Odoo covers CRM, sales, projects, field service, inventory, invoicing, and accounting, but we did not verify a current Hungary localisation page. Require the implementation partner to demonstrate VAT, Online Számla, structured invoices, bookkeeping, audit, and export in the purchased version. Add specialist design and build the distribution operator workflow with an accountable partner.
Run the same three opportunities in every shortlisted CRM: one ordinary lead, one revision-heavy project, and one deal that already failed. This removes demo theatre and exposes repeated entry, stale documents, weak mobile adoption, and missing local support.
Capture a real lead, assign it, create the proposal, schedule follow-up, record acceptance, and hand it to delivery.
Change the system, equipment, price, payment route, and installation date. Identify every stale record.
Use a duplicate, missed follow-up, rejected proposal, or delayed job and ask the CRM to show what happens next.
Create a Hungarian-forint quotation with consistent HUF display, line-level tax, deposits, milestones, finance or leasing, discounts, exclusions, validity, and revisions. State the bill and consumption source, system size, production method, degradation, self-consumption, export, tariff source, rate, checked date, battery behaviour, and sensitivity. Test residential and non-residential templates separately.
Build outright-purchase, service, mixed-item, staged-payment, cancellation, credit-note, and debit-note samples. Confirm who sets VAT classifications, which system issues the invoice, what passes into Online Számla and the required structured-invoice route, how statuses return, where identifiers and QR evidence sit, and how accounting reconciles it. Obtain current tax and structured e-invoice advice.
Record the live route for new 2026 work, including the customer, site, electricity supply identifier, distribution operator reference, responsible electrical professional, supplier, and export or settlement counterparty where applicable. Preserve capacity, equipment, documents, submission version, queries, responses, approval, expiry, and owner. Require a live demonstration before treating a link or compliance label as a distribution operator submission. Keep legacy settlement contracts only on historical cases.
Test a small home system, a home battery, a larger commercial connection, and a project with distribution operator conditions. Store the application, electricity supply and meter data, capacity, equipment, drawings, protection settings, communications, costs, conditions, approval, changes, and commissioning. Use current distribution operator material and leave technical decisions to licensed and authorised people.
Residential work needs household contacts, bill and roof data, domestic export assumptions, financing, appointment, and customer communications. Commercial work can require site and billing entities, maximum demand, load profiles, procurement stages, lease or PPA terms, technical studies, approvals, multiple decision-makers, and staged delivery. Test separate pipelines with common reporting and make sure a site, account, opportunity, contract, and installation are not collapsed into one record.
Create the proposal, selected customer messages, consent notice, form labels, terms, and handover checklist in English and Hungarian, then have a fluent reviewer assess both versions. Test Hungarian names, addresses, phone numbers, dates, fonts, and HUF values. For WhatsApp, confirm the approved channel, templates, opt-in evidence, conversation ownership, attachments, suppression, retention, and export. Field users should complete core work on phones with weak connectivity considered.
Collect the vendor privacy notice, processing terms, security measures, current subprocessors, hosting and backup locations, support-access countries, incident commitments, cross-border transfer position, retention schedule, deletion process, and usable export. Run a customer access and correction request, consent withdrawal, marketing suppression, staff permission change, account closure, and deletion request. Document the installer's own purposes and retention rules instead of copying vendor language unchanged.
Map the exact systems used for bank transfer, cards, finance, accounting, inventory, email, calendar, telephony, signature, design, and reporting. Verify Hungarian availability, currency, fees, tax fields, sync direction, duplicate handling, error alerts, retries, permissions, and exit export. Obtain local or regional support hours, languages, response routes, implementation scope, data-migration responsibility, and escalation terms in writing.
A field user should receive the accepted scope and latest drawing, complete the site survey, record equipment and serial numbers, attach photographs, log deviations, and capture the single-line diagram, test results, responsible electrical professional evidence, contractor records, defects, distribution operator and meter status, supplier or export correspondence, commissioning information, warranties, manuals, customer training, and signed handover. Approved files must remain versioned and exportable.
Import duplicate leads, bilingual contacts, multi-site customers, historical settlement cases, open grid-connection jobs, quotations, documents, consent, tax fields, and invoice references. Test roles for sales, design, grid administration, field, finance, management, and contractors. Inspect changes to prices, assumptions, documents, customer details, and status. Export records, attachments, messages, history, and configuration.
The real budget
The shortlist mixes Indian rupees, US dollars, unqualified dollar symbols, per-project charges, free internal products, and custom quotes. Do not convert these into a single HUF table and imply Hungarian contracts, taxes, support, or payment methods that have not been verified.
India-facing public pricing. Pro requires at least three users. Hungarian terms are unverified.
No public Hungarian list price found. Request HUF billing and full implementation terms.
Seat conditions apply. Individual plan is $1,899/user/year. Confirm currency and Hungary terms.
External API Access became paid from 16 April 2026; supported connectors are billed separately.
Quickest publishes Free with 10 proposals per month for one user and Pro at ₹6,999 per user per year with a minimum of three users. These are India-facing public terms. No verified HUF price, Hungarian VAT treatment, contract entity, payment route, local support commitment, or Hungary data terms were found. Obtain a written quotation and complete security review.
Arka360 has no public Hungarian list price on the checked pages. Request HUF billing, limits, imagery, onboarding, migration, support, integrations, taxes, renewal, and exit costs. SurgePV publishes annual per-user prices in dollars: $1,899 for an individual plan and displayed team tiers at $1,499 and $1,299, subject to seat conditions. Confirm currency and Hungary terms.
OpenSolar says its core app remains free for end-to-end internal work. API Access became paid from 16 April 2026, and supported connectors follow separate billing. A stack that sends data to an external CRM or accounting product therefore needs a written connectivity estimate. Pylon displays $4 for a Standard project, $10 for a Pro project, and $49 per user per month for Solar CRM. The checked page does not clearly label those dollars as HUF.
Zoho CRM's global page displays Free for three users, Standard at US$14, Professional at US$23, and Enterprise at US$40 per user per month. Confirm billing basis, HUF billing, tax, WhatsApp charges, storage, implementation, and app costs. Odoo offers One App Free and paid all-app plans. Obtain a Hungary quote for hosting, users, localisation, implementation, custom work, support, and maintenance.
Our number-one pick
Quickest ranks first because this comparison gives the most weight to proposal-first value and adoption. A focused lead, quotation, follow-up, and pipeline path may be easier for a small seller to trial. The free plan shows whether staff keep records current.
The recommendation is conditional and commercially disclosed. QuickEstimate publishes this guide and sells Quickest. We found no public proof of HUF quotations, Hungarian VAT, Online Számla, buyer-required structured invoices, MVM Hálózat or distribution operator workflows, current HMKE connection and settlement terms, legacy settlement records, responsible electrical professional evidence, battery assumptions, Hungarian documents, GDPR processor and transfer terms, Hungary support, local payments, accounting, integrations, installation, testing, commissioning, metering, or handover.
Quickest uses rupee pricing and says customer data is hosted in AWS Mumbai. Review the contracting entity, processor terms, subprocessors, storage and backup regions, support access, cross-border transfers, security, incidents, retention, deletion, and export before uploading customer information.
OpenSolar is the better evidenced choice when accessible solar design and proposals matter most. Odoo is the broad operations candidate, but its Hungarian localisation is unverified. SurgePV, OpenSolar, and Pylon deserve design-led trials, while Zoho suits teams ready to configure a generic CRM and connect several specialist systems.
Run a home system, a battery case, and a larger commercial connection. Use real sales, design, grid, field, finance, and management users. Record corrections, duplicate entry, stale versions, missed tasks, mobile friction, integration errors, and support. Quickest earns rollout only when every local gate passes.
Your next move
Start with Quickest and the specialist closest to your largest local requirement. Use the same evidence and test deals for both.
Name the bottleneck. Pick lead response, proposal speed, design, payment, install handoff, or management visibility.
Choose two tools. Compare Quickest with the strongest specialist for that bottleneck.
Run the Three-Deal Proof. Score adoption, repeated entry, revision handling, support, and full annual cost.

Common questions
Quickest is our first proposal-first adoption trial. QuickEstimate publishes this ranking and sells Quickest, whose Hungarian localisation is unverified. OpenSolar is the accessible design-led alternative. Odoo is a broad ERP candidate, but its Hungarian localisation is also unverified. Rollout depends on HUF, VAT, distribution operator, MVM Hálózat, applicable HMKE settlement, responsible electrical professional, GDPR, Hungarian document, accounting, battery, field, and handover tests.
Do not assume one method. Identify the distribution operator, HMKE eligibility, commissioning date, feed-in status, metering arrangement, supplier, settlement regime, contract version, and any storage interaction. Date every import and export price, regulated charge, fee, production, consumption, self-use, and battery assumption, then show sensitivity rather than guaranteed savings. Have the supplier confirm the live billing treatment in writing.
Do not infer submission from a stage labelled distribution operator approved. Ask the vendor to demonstrate the supported integration, fields, documents, permissions, statuses, validation errors, and updates. For a manual portal, the CRM can still control approved source data, owners, deadlines, versions, references, returned queries, responses, meter status, and completion evidence. None of the shortlisted products had a publicly verified direct distribution operator integration.
Use the current adviser-approved Hungarian rate for each line. Equipment, installation, batteries, services, repairs, finance, and building work can receive different treatment as law and transaction facts change. Store the code, source, and effective date, then have a Hungarian adviser approve deposits, milestones, corrections, credit notes, cross-border purchases, invoice wording, and reporting before launch.
Not for every required route. Test tax and customer identifiers, recipient routing, the required structured format, Online Számla reporting, validation, delivery or rejection, corrections, credit notes, attachments, retention, accounting reconciliation, permissions, and export. The European Commission records a structured B2G framework and VAT reporting environment. Verify current scope with a Hungarian adviser and test the exact purchased software implementation.
Request Article 28 processor terms, security measures, subprocessors, storage and backup regions, support-access countries, transfer safeguards, incident commitments, retention, deletion, and complete export. Test access, correction, objection, consent withdrawal, marketing suppression, permissions, and closure. Quickest states AWS Mumbai hosting, so a Hungarian buyer must assess international transfers and every connected messaging, signature, analytics, support, and backup service.
Preserve the accepted design, distribution operator conditions and references, equipment and serial numbers, inverter and battery settings, single-line diagram, responsible electrical professional, responsible electrical professional evidence, inspection and test records, photographs, deviations, commissioning, meter work, applicable HMKE settlement setup, warranties, manuals, customer instruction, defects, and signed handover. Include attachments and history in the exit export.
Run a home system, a battery project, and a commercial job through real sales, design, office, field, and finance users. Complete the HUF quotation, VAT, contract, distribution operator handoff, applicable HMKE settlement assumptions, installation, commissioning, responsible electrical professional record, Online Számla and structured-invoice exchange, and handover. Record corrections, duplicate entry, stale documents, missed tasks, mobile friction, integration errors, support answers, and total contract cost.
Use the Three-Deal Proof and require every vendor to show the same lead, revision, document, and failed handoff.
