Plays well with your stack

Housing Associations don't start from zero. The HMS has been in place for a decade. The finance team has its ledger. Compliance lives in the document management system. Someone in IT spent years getting identity right. Software that asks teams to move everything across never lands.

Stairpay was designed to slot in, not to replace.

Integrate first, replace never

Every piece of housing software claims to be the one source of truth. We don't. The HMS is the source of truth for tenancies. The finance system is the source of truth for the ledger. The DMS is the source of truth for the executed lease. Stairpay is the source of truth for what happens between those systems — the case, the milestones, the resident journey.

Connectors aren't a tax we paid to be enterprise-ready. They're the product.

What we integrate with today

Housing management systems — two-way for tenancy, contact, and unit data; read-only for ledger lines unless the HA explicitly opts in.

Finance and accounting — staircasing settlements, service-charge adjustments, and resale completions pushed as journal entries against a chart of accounts the finance team controls.

Document management and e-signature — templates live in the DMS; Stairpay triggers envelopes, tracks status, and pulls executed copies back against the case.

Identity and SSO — SAML or OIDC, with SCIM provisioning where wanted. No long-lived service accounts on our side.

Comms — outbound SMS and letters via the HA's preferred sender. Replies route to the HA's existing inbox.

How the data moves

Four rules govern every integration:

1. Least privilege. Connectors get the narrowest scope that does the job.
2. Auditable both ways. Every read and write is logged with actor, timestamp, and payload hash, exportable at any time.
3. No silent transformations. Mappings are visible in the admin UI and version-controlled.
4. Backpressure on errors. When an upstream system rejects a write, Stairpay holds the change for human review rather than retrying blindly or dropping it.

Building a new connector

If your stack includes something we haven't listed, the path is short: a scoping call, a data-flow diagram signed off by your IT and DPO, and a sandbox build before anything touches production. Most net-new connectors land inside six weeks. The work is ours, not yours.

The best housing software is the kind the rest of your stack barely notices is there. That's the bar we hold ourselves to.
