The money is in the milestones — and that is where it leaks

If you are a builder selling under a construction-linked plan, your cash does not arrive in one clean cheque. It comes in slabs: a bit on booking, more on foundation, more on each slab casting, on brickwork, on plastering, and the balance at possession. Every one of those slabs is a demand you are supposed to raise, on time, with the right amount, to the right buyer. Miss one, raise it late, or lose track of who has paid what, and you are quietly financing your buyer's flat for free while your own contractor waits to be paid. Multiply that across a hundred units and the leak is not small.

The 10% rule you cannot ignore

Before the collections conversation even starts, there is a compliance one. Under Section 13 of the Real Estate (Regulation and Development) Act, a promoter cannot accept more than 10% of the cost of a flat, apartment or plot as an advance or application fee without first entering into a written, registered agreement for sale. Booking amount, token, application charge — it all counts toward that 10%. A lot of builders still collect more on a plain receipt and "do the agreement later." That is exactly the kind of shortcut a buyer can take to RERA, and the penalties and refund orders are not worth the few weeks of early cash.

Running collections properly means the system itself should know when a unit has crossed 10%, and should hold the next demand until the agreement for sale is registered. That is a control, not a nice-to-have.

Co-buyer part-payments: the split nobody tracks cleanly

Indian property is very often bought jointly — husband and wife, father and son, two brothers. They rarely pay in equal halves, and they rarely pay at the same time. One transfers 60% from his account, the other pays 40% three weeks later, and TDS under Section 194-IA has to be deducted and reported for each of them separately. Now try tracking that in a CRM that treats a unit as a single payer with a single ledger. You end up with receipts that do not tie out and a TDS mismatch waiting to surface.

Leads, bookings, demand letters and collections belong on one thread — not scattered across chat and spreadsheets.

Demand letters that actually go out on time

The fix for the milestone leak is boring and mechanical, which is exactly why software should do it. When a construction stage is marked complete, the demand should generate itself for every applicable unit and go out with the right figures. What that looks like in practice:

Milestone triggers tied to construction stages, not to someone remembering.
Auto-generated demand letters with due dates and the correct slab amount.
Interest on delayed payment calculated automatically, per the agreement.
Reminders before and after the due date, and receipts on payment.
Records kept in a form that keeps you clean with RERA and your auditor.

A demand letter that goes out three weeks late is an interest-free loan you never agreed to give.

Sell.Do, Zoho and LeadRat — named fairly

Sell.Do is a capable, real-estate-specific CRM, but it is priced and built for larger developers, often in the ₹20,000 to ₹60,000 a month range; Zoho is a powerful general CRM that you can bend into real estate if you have the patience and someone to configure it; LeadRat is sharp on lead capture and follow-up. All three do real work. The gap most of them leave for a one-to-three project builder is the money side after the sale: construction-linked demand letters, co-buyer ledgers, interest on delays, and collections that reconcile. That is not where a lead-first CRM spends its energy.

Where BizRevolt fits

BizRevolt's real estate workspace runs the whole thread — lead, to booking, to construction-linked demand letters, to collections — with co-buyer splits and RERA-aware records built in rather than bolted on. Live unit availability, channel-partner commissions and a buyer self-service view sit alongside it, so the sales team and the accounts team are finally looking at the same numbers. It is ₹999, ₹1,599 and ₹2,499 per user per month depending on the tier, which is deliberately sized for the mid-market builder that the big platforms price out.

If your demand letters currently depend on someone remembering to send them, that is the first thing worth fixing. Message or call the founder directly on +91 91 0657 4865 and we will walk through your current collection flow with you — no obligation, no hard sell.

Channel partners, portals and the leads you already paid for

Before a single demand letter is ever raised, there is money leaking at the very top of the funnel. Most builders spend real budget on 99acres, MagicBricks and a network of channel partners, and then lose a chunk of those hard-won leads in a WhatsApp forward that nobody follows up. A lead you paid a portal for is worth exactly nothing if it dies in an inbox. Capturing every enquiry automatically, attributing it to the portal or partner that sent it, and settling partner commissions transparently is where that marketing spend stops draining away.

Leads from 99acres, MagicBricks and your own website captured into one place automatically.
Clear attribution to the channel partner or portal that sourced each enquiry.
Channel-partner commissions tracked and settled without a monthly argument.
A single view of which source actually converts, so the next rupee is spent well.

Fix the top of the funnel and the collections discipline further down has far more to work with in the first place.
