From WhatsApp groups to a real CRM — a 30-day migration plan
Most Indian solar installers run on WhatsApp groups, an Excel sheet and a printed bill book. Here's exactly how to migrate to a real CRM without dropping any leads or losing your team.
"Sir, we use WhatsApp groups, Excel and a bill book — and it works fine."
This is the most common sentence we hear in our first call with a new installer. And it's mostly true. Until it isn't. Until you can't find a customer's installation photos because they're in someone's old phone. Until you bill a customer twice. Until you miss a PMSG inspection because no one updated the spreadsheet. Until your senior engineer leaves and takes 800 customer contacts with him.
The good news: migrating off WhatsApp + Excel is much less work than installers think. A small EPC can realistically do it in a single weekend. Below is the exact 30-day plan we recommend.
Week 0 (the weekend before) — Sign up & clean
- Day 1 (Saturday morning, 2 hours): Create your SolarIonix trial account. Add your organisation details, GSTIN, address, bank account, logo. This takes 15 minutes. The remaining 1h45m is filling in your products catalog — every panel, inverter, structure, cable type and brand you typically use.
- Day 1 (Saturday evening, 3 hours): Add your team — owner, sales lead, ops engineer, accounts. Set roles. Each person installs the mobile app on their phone and logs in.
- Day 2 (Sunday, 4 hours): Open your Excel sheet. Export your last 6 months of leads + active projects to CSV. Import to SolarIonix. This is where the heavy lifting happens, but the importer handles 95% of fields automatically.
Week 1 — Run in parallel
Critical: don't switch off WhatsApp on day 1. For the first week, run both systems in parallel. Every new lead goes into both SolarIonix AND the WhatsApp group. Every project update goes in both. Yes, it's annoying. It's 5 days of double-entry.
Why: it builds the habit of opening SolarIonix first. By day 7, your team will start to notice they're typing into SolarIonix and forgetting WhatsApp.
- Daily 10-minute standup at 9 AM looking at the SolarIonix Kanban board, not WhatsApp scrollback.
- Use the mobile app for all site photos.
- Generate one real GST invoice from SolarIonix to learn the workflow.
Week 2 — Cut the WhatsApp group, keep WhatsApp messaging
Make this a rule on Monday morning: "From today, lead and project updates do NOT go in the WhatsApp group. They go in SolarIonix." The group is now only for personal chat with customers. The CRM is for everything else.
Expect resistance. Your senior engineer will say "but I prefer WhatsApp". Stay firm. Within 4 days, the team gets it.
- Archive the old WhatsApp groups (don't delete — you might need them for audit).
- Run a Tuesday afternoon training session: 30 minutes on the lead Kanban, 30 minutes on the mobile photo workflow.
- By Friday, your team should be entering 100% of new leads into SolarIonix.
Week 3 — Catch up on the back catalog
You probably have 20–50 ongoing projects that pre-date your migration. This week is about back-filling them.
- Pick your 10 most active projects. Create them in SolarIonix. Mark each at the correct stage.
- Move existing site photos from WhatsApp/phones into the project gallery (the mobile app makes this trivial — just pick from your gallery).
- For the inactive 20–30 projects: create them as "completed" with minimal data. Just enough that they show up in your customer history.
Week 4 — Lock in the habits
By week 4 the muscle memory is forming. This week is about removing the last excuses.
- Customise your invoice PDF with your logo, GSTIN and bank details. From now on, every quote and invoice goes through SolarIonix.
- Set up payment recording — every time a customer pays, your accounts person enters the payment into the relevant invoice. This is the make-or-break habit. If you do this, your dashboard becomes accurate and useful.
- Define your weekly routine: Monday morning is "review the Kanban", Friday afternoon is "review the dashboard". Two meetings. That's it.
What changes after 30 days
- You stop losing leads. Every enquiry has a status, an owner and a follow-up date.
- You stop arguing about who said what to which customer. The notes are in the lead record.
- You can answer "how many projects are in installation right now?" in 2 seconds, not 20 minutes of WhatsApp scrolling.
- Your accounts catch up. Outstanding goes down because you can see exactly which invoices haven't been paid.
- If a senior engineer leaves, the customer relationships stay with the company.
What doesn't change
WhatsApp is still where you talk to customers — that's not going away in India. SolarIonix is where you track what was discussed. Customer says "send me the proforma" on WhatsApp → you generate the proforma in SolarIonix → you share the PDF link in WhatsApp. Two tools, two jobs.
