ProofPay · the flagship

Pay only for verified work.
Audit every rupee.

Workers check in with a geofenced selfie bound to a specific task. A supervisor co-signs. Wages, PF, ESI and PT are computed deterministically from the proof log. Every payment line is reproducible — disputes resolve to a single proof, not the whole batch.

  • Multi-factor attendance proof — GPS + on-device liveness selfie + supervisor co-sign + device fingerprint, hashed into one WorkProof.
  • Deterministic payroll — same proofs + policy snapshot always yield the same payout. No back-channel adjustments.
  • Line-level disputes — challenge a single proof, not a whole muster roll. The audit hash makes tampering detectable.
  • Event-graph Risk Engine — a deterministic, auditable score derived from the project's event graph (proof gaps, critical issues, RFI backlog, budget burn). Every score ships with an inputs hash for replay.
  • Compliance Copilot — DPRs + WorkProofs + POs auto-fill RERA returns, BOCW registers, GST input ledgers, with per-field provenance back to source events.

The WhatsApp graveyard
Critical decisions buried in a group chat with 47 unread messages and three forwarded videos.
The Excel arms race
Every role keeps their own sheet. Numbers never match. Disputes happen at the end, when it's expensive.
The blame loop
Architect blames contractor. Contractor blames supplier. Client blames everyone. Nobody has the receipts.
Who it's for

Six roles. Six dedicated workspaces. One project of record.

Each stakeholder logs in to a workspace built around the decisions they make. No training. No "where do I click". Just the view that fits the job.

Portfolio control
Developer
Live health scores across every project. AI-flagged risks before they slip. One dashboard from Andheri to Whitefield.
Daily command
Contractor
Labour, supply, compliance and site issues in one place. WhatsApp out. Source of truth in.
Design + RFI loop
Architect
Versioned drawings, RFIs that don't get lost, DPR approvals you can stand behind.
Hindi-first, mobile-only
Worker
Today's task list, attendance and wages — in the worker's language, on a phone they already own.
Order to payment
Supplier
Confirm POs, schedule deliveries, track outstanding — without a single follow-up call.
Calm visibility
Client
Progress, milestones and site status — the way you wish your last project had shown you. No budgets, no noise.
What you get

The boring infrastructure your site has been missing.

Daily Progress Reports. Site issues. Permits. Payments. Notifications. Roles. Audit trails. Built like enterprise software, priced like it understands a job site.

DPRs that get approved
Daily Progress Reports flow Contractor → Architect → Client with status, comments and audit trail.
Site issues, not WhatsApp screenshots
Flag, photograph, assign, resolve. Severity-tagged and notified to exactly the right people.
Permits & compliance in one folder
BMC, RERA, fire, labour — expiry dates, attachments, renewals. Stop digging through email.
Payments without the spreadsheet war
Milestone payments, supplier outstanding, labour wages — one ledger, every role sees what they should.
AI portfolio scan
Run an AI sweep across projects to surface risk, late milestones and burn-rate anomalies.
Hindi for the people building
Worker app ships bilingual. Because the people pouring the slab shouldn't need English.
Real-time notifications
Submissions, approvals, rejections, RFIs — pushed to every stakeholder, the moment they happen.
Trust boundaries by design
Row-level security mirrors the real org chart. Workers don't see budgets. Clients don't see wages.

03
STEP 03
Run the site
DPRs, RFIs, issues, payments — everyone working off the same picture, in real time.
Built secure

Security that mirrors the real world.

Row-level security on every table. Workers don't see budgets. Clients don't see wages. Architects don't see other architects' designs.
Server-validated invitations. A token only works for the email it was sent to, once.
No anonymous reads on sensitive data. PAN, GST, phone numbers and project records are scoped to people who actually share the project.
Notifications can't be spoofed. Cross-user alerts go through a server function that verifies the sender is a project member first.
Files signed at access time. Project uploads aren't world-readable URLs — short-lived signed links only.
FAQ

Honest answers.

Do my workers need to learn English?+

No. The worker app ships in Hindi and English, with one-tap language switching. It is built for the phone in their pocket — not a desktop they don't have.

What does it cost?+

Free to start. You can run a project end to end without paying anything while we're early. Paid plans for larger portfolios will roll out transparently, with no surprise lock-in.

Does it replace WhatsApp?+

It replaces WhatsApp for work that has a status — DPRs, RFIs, site issues, payments, permits. Keep WhatsApp for chai. Use banao for everything that has consequences.

Who can see what?+

Permissions follow the real org chart. A worker sees today's task and wages. A client sees progress and milestones, not wages or budgets. A developer sees the full picture across projects. It is enforced in the database, not on the screen.

What about my existing data?+

Add projects, members, drawings, permits and payments as you go. Most teams onboard one live project first and migrate the rest within a few weeks.

Build the next one without the chaos.
