Complete governance for residential developers

One source of truth for your portfolio.

Full control from unit release to final payment. Unify inventory, pricing and audit trails across your teams.

Sales and finance, one ledger

Eliminate weekly reconciliation.

Stop chasing spreadsheet discrepancies. When sales tracks bookings on a whiteboard and accounts tracks money in Tally, the numbers drift.

One real-time ledger. Every flat status and payment instantly verifiable.

Harmony links sales bookings and accounting into one ledger, so the number in the review is the number in the book, with a name and a time on it.

Governance, not just tracking

Built-in operational controls.

A CRM helps you chase a lead. Harmony is built so that a booked flat, a received rupee and an approved discount remain verifiable facts, months later and under audit.

Control 01

Prevent double-selling.

Server-enforced holds ensure a unit is only available when it is fully clear. A held flat carries a name and a 7-day clock, and the reason a unit is off the market is never disclosed to those not entitled to it.

B-7033 BHK · 1,865 sftBlockedfor Ravi Kumar · 6d 22h
What every other executive sees: B-703 is currently under discussion by another executive. Nothing more.

Control 02

Centralized pricing.

Base rates and totals are computed and validated on the server from the area on record and checked against the floor. Discounts require director sign-off before they take effect.

AptComputed totalDiscountStatus
B-703₹1,42,00,000₹1,20,000Pending Discount
Recomputed from 1,865 sft on record. BSP cannot be below the floor. Awaiting a director.

Control 03

Enforced separation of duties.

Roles are strictly segregated. Sales execution, discount approvals and payment verification remain independent: a director raises a payout and only an accountant releases it, and receipt numbers are issued by the server so two people cannot collide.

Control 04

A complete audit trail.

Every decision above lands in an append-only log: who, which role, what changed, before and after. When the question is "who approved that discount", the answer is on record.

Release to receipt

The journey of one apartment.

B-703 passes through six hands. Each one leaves a line in the ledger, and none can alter another's.

  1. Released

    S. Venkatesh, director, releases the seventh floor of Cluster B to sales. Until now B-703 was Un-released, the default.

  2. Blocked · 6d 22h

    Arjun Nair blocks it for 7 days, for Ravi Kumar. A block has to be held for someone.

  3. BookedPending Discount

    Ravi Kumar and a co-applicant. A discount of ₹1,20,000 is requested, with a reason. The price does not move until a director decides.

  4. Active

    Discount approved. The total is recomputed by the server. A payment plan turns it into dated milestones: on booking, on stages, on handover.

  5. Due

    The director marks the seventh floor slab complete. That milestone falls due on every booking in Cluster B at once. A financial event, and the app says so before the click.

  6. Receipted

    ₹8,40,000 by cheque, cleared at the bank. Approved by Meera Iyer, receipted SR/2026/I/0117. The channel partner's commission is computed the same minute: gross, 194H, net.

For the finance team

Money, specifically.

Four things a collections desk asks about on day one, and how each is handled.

A schedule that follows the building.

MilestoneTriggerShareStatus
BookingOn booking10%Paid
FoundationOn project stage10%Paid
7th floor slabOn project stage15%Due
14th floor slabOn project stage15%Pending
FinishingOn project stage25%Pending
HandoverOn manual event25%Pending

Approved money waterfalls down the schedule in order and nets off reversals. Partial is a real state, not a note typed into a cell.

A cheque's whole life.

  • Awaiting receiptregistered, with an image
  • Receivedconfirmed in hand
  • Awaiting clearancedeposited
  • Clearedpayment auto-created
  • BouncedInsufficient funds

A cleared cheque becomes an approved payment on its own. A bounced one records why, and what happened next.

194H, computed, not remembered.

Gross commission₹2,40,000
TDS (194H) 2%₹4,800
Net payout₹2,35,200

A director raises the payout and an accountant releases it. The person who decides the amount is never the person who releases the money.

Four kinds of money entry: payment, reversal, refund, write-off. Each its own line, each with a reason from a fixed list.

Every figure on this rail is fictional demo data, set in the product's real formats.

White label, by design

Your name on it.

Each developer runs their own instance. A buyer sees your project and your company: in the bar, on the confirmation letter, on the receipt. Harmony's own mark never goes on a document.

Type your own. The specimens re-brand as you go, and the name carries into the demo form at the end.

Who it is for

Built for real estate developers.
