SaaS Development for Proptech
In short
Aqib Ops builds proptech SaaS in 10–14 weeks. We deliver MLS / IDX integrations, transaction-stage workflows with role-aware permissions (agent, broker, client, lender), DocuSign or Anvil e-sign, escrow-aware Stripe Connect flows, and the operator console brokers actually need.
The problem
Proptech is a permissions and integrations problem disguised as a UI problem. Most builds underestimate MLS data licensing, the volume of role-conditional logic in a real estate transaction, and how unforgiving brokers are about a clunky signing flow.
Our approach
We model the transaction state machine first (offer → counter → contract → financing → close) with role-conditional permissions baked into the database. MLS / IDX is treated as a syncing problem (incremental ETL, not live API hits per page view). E-sign and escrow are wired in week one.
Stack we'd reach for
Next.js + tRPC
Type-safe transactions; serverless-friendly for spiky listing traffic.
Postgres + PostGIS
Geospatial queries for listing search without a separate search engine.
RESO Web API / IDX feeds
Standards-compliant MLS sync; ETL into your own database for performance and rights compliance.
DocuSign or Anvil API
E-sign without rebuilding the legal-ops side from scratch.
Stripe Connect + escrow
Earnest money + commission flows with proper audit trail.
What you'd get
- Transaction state machine with role-aware permissions
- MLS / IDX sync via RESO Web API (incremental + reconciled)
- E-sign integration (DocuSign, Anvil, or Dropbox Sign)
- Stripe Connect for earnest-money escrow + commission splits
- Broker / agent / client / lender portals from one codebase
- Document repository with version history and audit log
Frequently asked
Can you integrate with the MLS?
Yes, via the RESO Web API (the modern standard) or legacy RETS feeds where required. We sync incrementally into your own Postgres so you control performance and stay compliant with display-rights rules.
What about e-sign and escrow?
DocuSign, Anvil, or Dropbox Sign for e-sign. Stripe Connect with explicit hold + release for earnest-money escrow. We model both into the transaction state machine so audit trails are continuous, not stitched together.
How do you handle role-based permissions?
Every entity (listing, document, message, payment) has explicit role-scoped read/write rules at the database layer. A buyer's agent can't see a seller's net sheet. A lender sees the disclosure package, not the messaging thread. We model this in week one, not as a bolt-on.
Are you familiar with NAR settlement / commission rule changes?
Yes — the 2024 NAR settlement changed how commissions are disclosed and negotiated. We model commission flows with explicit buyer-side agreements and audit trails that align with the new requirements.
What does a proptech MVP cost?
Most proptech MVPs we ship land between $50k and $120k depending on MLS scope (regional vs national), e-sign + escrow depth, and how many role-portals you need at launch.
