How to Send a Solar Proposal on WhatsApp

Your customer just asked for a quote. You're standing in their parking lot, phone in hand. You could say "I'll email it tonight", or you could send a branded, subsidy-ready PDF proposal on WhatsApp before you've driven out of their colony. The second option puts your quote in their hands while their interest is highest.

WhatsApp is India's default business communication channel. Most of your customers already use it every day, so a proposal there is easy to open and easy to forward. A proposal sent by email might get read on Tuesday. On WhatsApp it is more likely to be seen the same day.

This guide walks through exactly how to send a solar proposal on WhatsApp, with the specific steps in Quickest Solar CRM, and how to time your follow-up.

Why WhatsApp is the right channel for solar proposals in India

In the Indian solar sales context, WhatsApp has three advantages over email that directly affect close rates.

First: visibility. A WhatsApp message lands where the customer already looks many times a day, while a business email can sit unread for days. A solar proposal that isn't opened is a deal that doesn't close.

Second: channel familiarity. Your customer uses WhatsApp to communicate with their family, their CA, and their local kirana, it's a trusted channel. A proposal in WhatsApp has the same trust weight as a message from a known contact, and that trust compounds further once you're sending from a WhatsApp green tick verified account. An email from an unfamiliar domain can land in Promotions or spam.

Third: immediacy triggers action. When a proposal arrives on WhatsApp while the customer is still thinking about solar (right after the site survey), they're more likely to share it with their spouse or family decision-maker. That same proposal sent by email the next evening arrives when attention is somewhere else entirely.

The 3-Tap Proposal Delivery System, the named framework

The 3-Tap Proposal Delivery System is a simple way to deliver a proposal on WhatsApp straight after a site survey. It has three components:

Tap 1, Generate: Enter the customer name, site address, and system size (kW). Quickest Solar CRM applies the PM Surya Ghar subsidy in the proposal. The proposal PDF is built from your proposal template, with your logo, items, product photos and terms and conditions.

Tap 2, Brand: Preview the proposal. If your quotation pricing needs adjusting (e.g., you're using a specific panel brand or inverter model), update the items in the proposal. Add a personal note, a single line like "Based on your south-facing terrace, this 3 kW system is sized for your household consumption", in the WhatsApp message.

Tap 3, Send and log: Share the proposal PDF on WhatsApp with your short message. Then log the activity on the lead in Quickest Solar CRM and set a follow-up reminder, so the next touch does not depend on anyone's memory.

1. 1

   Generate, Create the proposal in the Quickest Solar CRM app

   Open Quickest Solar CRM → create a new proposal → enter customer name, mobile number, site address, and proposed system size in kW. The PM Surya Ghar subsidy is applied in the proposal.

2. 2

   Brand, Verify your logo, company name, and cover message

   Preview the proposal PDF. Your company logo, items, product photos and terms are already in your proposal template. Edit the WhatsApp message to personalise it with a specific reference to the customer's site ("your 250 sq ft terrace in Bopal," "your Mehsana factory rooftop").

3. 3

   Send and log, Share on WhatsApp and set a follow-up reminder

   Share the proposal PDF on WhatsApp to the customer's number, with your short message. Then return to Quickest Solar CRM, log the activity on the lead (it shows on the lead's timeline) and set a follow-up reminder.

What makes a WhatsApp solar proposal different from an email proposal

The format and content of a proposal optimised for WhatsApp differs from one designed for email in three specific ways.

Shorter cover message. On WhatsApp, the preview text before the customer opens the PDF is your first impression. Keep your WhatsApp message to 3–4 lines maximum: one line of context ("Here's the solar proposal for your Vatva residence"), one line with the headline number ("3 kW system, ₹1.07 lakh after subsidy, saves about ₹19,800/year"), and one call to action ("Open the PDF and let me know if you'd like to adjust the system size.").

PDF, not a link. India's mobile internet is patchy in many areas. A PDF file saved in the customer's WhatsApp storage is always accessible, even when they're checking it at 11pm with poor signal. A link to an online proposal requires an active connection and doesn't feel as permanent or professional. In Quickest Solar CRM, the proposal always goes as a PDF attachment.

Subsidy front and centre. For solar proposals in India, the PM Surya Ghar subsidy amount is the headline number. Your customer will forward your proposal to their family members on WhatsApp, and those family members will look at the total cost after subsidy first, annual savings second, and everything else third. A proposal that buries the subsidy in page 3 doesn't share well.

For detailed guidance on what to put inside the proposal PDF itself, see what to include in a solar quote, solar proposal best practices, and how to present ROI in a solar proposal.

Follow-up after you send, and what the ticks tell you

Quickest Solar CRM does not tell you whether the customer opened the PDF, so you work with two things you control: WhatsApp's own ticks, and a follow-up reminder on the lead. In the WhatsApp chat you will see:

• One tick: the message left your phone.
• Two grey ticks: it reached the customer's phone.
• Two blue ticks: the customer has seen the message. Blue ticks only show that the message was seen, not that the PDF was opened, and customers can switch them off.

When you see blue ticks, that is a good signal to follow up soon, not in 3 days as part of a generic cadence, but while the proposal is fresh in the customer's mind. When you do not see them, the reminder you set on the lead tells you when to try again.

The follow-up strategy that pairs best with this is covered in detail in the solar proposal follow-up cadence guide. The short version: follow up the same day you see blue ticks, or on the reminder you set. A message like "Hi [Name], just checking you received the solar proposal, any questions on the system or the PM Surya Ghar subsidy?" works better than a cold follow-up 3 days later.

Common mistakes when sending proposals on WhatsApp

Most EPCs who send proposals on WhatsApp make one of these five errors. Each one costs deals.

Mistake 1: Sending at the wrong time of day. If you're sending from the site survey, send immediately. If you're in the office, send when your customer is likely to be free, which for homeowners is often the evening. That is an assumption, so note when your own customers reply and adjust.

Mistake 2: No personalisation in the cover message. "Please find attached the solar proposal" is worse than saying nothing at all. Use the customer's name, their city, and one specific detail from the site survey ("your 300 sq ft roof in Naranpura"). It signals that this isn't a mass blast.

Mistake 3: A generic company name on the proposal. If the customer receives a PDF branded "Proposal.pdf" with no logo and generic contact details, they can't tell you apart from the three other EPCs who sent a quote. Your logo, your company name, and your mobile number on the cover page is what makes it memorable.

Mistake 4: Forgetting the subsidy number. The PM Surya Ghar subsidy calculation is the reason customers call you back. A proposal that shows only the gross cost without the subsidy deduction looks expensive. Always show: gross cost → subsidy → net cost → annual savings → payback period. See how to calculate PM Surya Ghar subsidy for the correct calculation.

Mistake 5: Not following up once the proposal is sent. This is the most expensive mistake. If you sent the proposal 3 days ago and haven't followed up, the customer has either decided to wait, compared you with a competitor, or simply forgotten. Set a follow-up reminder on the lead the moment you send, and act on it.

How to set up Quickest Solar CRM for WhatsApp proposal sending

Before you can use the 3-Tap Proposal Delivery System, your Quickest Solar CRM account needs one-time setup:

Step 1, Brand profile: In Quickest Solar CRM, set up your proposal template with your company logo, items, product photos and terms and conditions. Do this once and every proposal uses it.

Step 2, Pricing configuration: The admin sets the price list and your margin. Once it is set, every rep quotes from the same price list, so no one invents a number at the customer's door.

Step 3, PM Surya Ghar subsidy settings: Check that the subsidy shown in your proposals matches the current central figures. The central subsidy is ₹30,000 for 1 kW, ₹60,000 for 2 kW, and ₹78,000 for 3 kW and above (per MNRE's CFA guidelines, July 2025 version). If your state has an additional top-up subsidy, state it separately in your proposal. The PM Surya Ghar National Portal maintains the latest approved subsidy figures, cross-check if you haven't updated your settings in the past 6 months.

Step 4, WhatsApp: There is nothing to connect. You share the proposal PDF from the app to WhatsApp on your phone, ideally the WhatsApp Business app, and keep your saved message templates ready for the cover message.

Sending proposals as a team, visibility and coordination

For EPCs with multiple sales reps, an illustrative 12-person team in Surat (not a real customer), for example, WhatsApp proposal sending creates a visibility problem: which rep sent which proposal, when, and who is following up? Without a system, two reps call the same customer, or no one calls because each assumes the other is handling it.

Quickest Solar CRM's team setup helps with this. When reps log each proposal on the lead, it shows on the lead's timeline, and the owner can see the dashboard and team report instead of chasing each rep for status updates. Lead stages and filters show which leads have a proposal out and no follow-up set. See the Team Management view.

For a solo installer, the same lead timeline and follow-up reminders work as a personal task list. No spreadsheet, no sticky notes.

For guidance on what a compelling proposal PDF should contain before you send it, see solar proposal example for India and the full guide on writing a solar proposal.

Consent, the Business App and Housekeeping

Send only with permission. Sending a proposal on WhatsApp is fine when the customer gave you their number and asked for it. It is a different thing to add them to a broadcast list or send promotional material they did not ask for. Keep proposals tied to an enquiry, respect it when someone asks to stop, and keep promotional messages on a separate, opt-in track. The WhatsApp Business API guide covers the stricter rules for outbound messages.

Use the Business app, not a personal number. Both can share a PDF, but the Business app gives you a company profile, a greeting message, labels and quick replies. Small and mid-sized installers usually find the free Business app enough. The API tier makes sense when volume, shared inboxes or CRM integration become the bottleneck.

Always send a PDF, never Word. A PDF keeps its layout on every phone, cannot be edited by accident and looks final. Name the file so it is easy to find later, for example SolarProposal_RajeshKumar_5kW_March2026.pdf, not Proposal.pdf. Make sure the PDF carries your branding and, where useful, a roof layout, equipment photos and a savings chart. Keep the full technical sheet as an attachment the customer can ask for.

Handle questions in the same thread. Customers will reply with questions about price, equipment, timeline or warranty. Answer promptly and briefly, use a voice note when something needs explaining, and send a photo or document to clarify. Save answers to common questions as quick replies, or start from the WhatsApp templates for solar follow-up. If the same question keeps coming up, add the answer to your proposal template. When a question needs new numbers, generate a revised PDF and send it straight away.

How Quickest Solar CRM fits the WhatsApp proposal workflow

The WhatsApp follow-up feature ties proposal sharing and reminders together in the 3-Tap Proposal Delivery System described above. Here's how the feature set maps to the workflow:

• Proposal Generator, Generate a branded PDF proposal from the mobile app (Android, iOS or web), with your logo, items, product photos and terms, and the PM Surya Ghar subsidy applied.
• WhatsApp Sharing, Share the proposal PDF on WhatsApp, use saved message templates for the cover message, and set a follow-up reminder on the lead.
• Lead Management, Every activity you log is on the lead's timeline. Customisable lead stages, labels and filters show which leads have open proposals and which are ready to close.
• Team Management, For multi-rep EPCs, the dashboard and team report show what each rep has logged, so you can spot reps who send proposals but do not follow up.

What to do this week, for your EPC

1. Send your next proposal on WhatsApp before you leave the site survey. Don't send it from the office that evening. Fill in the system size, subsidy, and cover message while you're still with the customer. Sending the proposal in the same visit is what makes your EPC memorable.

2. Set up the follow-up reminder habit. Every time you send a proposal, set a follow-up reminder on the lead for the same or next day. Make this a standing rule for your entire sales team. The proposal follow-up cadence guide has exact message templates for each follow-up stage.

3. Audit your last 10 proposals for subsidy accuracy. Check them against MNRE's July 2025 CFA guidelines. If your proposals still show old numbers, correct them and resend to any customer who hasn't responded yet. A corrected proposal often re-opens a stalled conversation.

Frequently asked questions

How do I send a solar proposal on WhatsApp?

Generate the proposal PDF in a tool like Quickest Solar CRM, which applies the PM Surya Ghar subsidy in the proposal, then share the PDF on WhatsApp with a short personalised message. You need the customer's name, mobile number, and proposed system size.

Does WhatsApp support PDF proposals?

Yes. WhatsApp supports PDF documents, and a branded solar proposal PDF is usually small enough to send without trouble (compress the images if yours is very large). The PDF appears as a document in the conversation, the customer taps to open it in their phone's PDF viewer. No app installation required on the customer's side.

What should I write in the WhatsApp message when sending a solar proposal?

Keep it to 3–4 lines: (1) contextual reference, "Here's the solar proposal for your [location] home/business"; (2) headline number, "3 kW system at ₹1.07 lakh after PM Surya Ghar subsidy, saves ~₹19,800/year"; (3) a call to action, "Let me know if you want to adjust the system size or have any questions." Avoid long paragraphs, they don't scan well on mobile.

How do I know if a customer has seen my WhatsApp proposal?

WhatsApp's own ticks show it: two grey ticks mean delivered, two blue ticks mean the customer has seen the message (unless they have switched blue ticks off). That is your cue to follow up while the proposal is fresh. Quickest Solar CRM does not report this for you, so set a follow-up reminder on the lead as a back-up.

Can I track if the PDF itself was opened?

Not with a plain WhatsApp send. Blue ticks show that the message was seen, not that the PDF was opened. Quickest Solar CRM does not track whether the PDF was opened, but you can log your follow-up on the lead's timeline and set a reminder, so the proposal never goes quiet.

How is a WhatsApp proposal different from an email proposal?

The format, not the content, is the key difference. WhatsApp proposals should have a short, personalised cover message (3–4 lines), a PDF with the subsidy and savings headline in the first section, and be sent immediately after the site survey while customer interest is high. Email proposals allow longer intros but are easier to miss and often arrive when customer attention is elsewhere, a gap covered channel by channel in WhatsApp vs SMS vs email for solar sales.

How do I make my solar proposal look professional on WhatsApp?

Use a proposal generator that applies your company logo, branding, and contact details to every PDF. The proposal should show: consumer name, site address, system size, panel and inverter brands, PM Surya Ghar subsidy deduction, net cost, annual generation, annual bill savings, and payback period, all on a branded template. See the solar proposal best practices guide for the full checklist.
