Hotel PMS Integrations — OTA, Payments, Locks and Accounting

Quick answer

Hotel PMS integrations connect the system of record to the channels, payment terminals, door locks, identity readers, telephony, POS and accounting. The value is not the number of logos; it is whether each interface is documented, monitored and owned when it fails.

Platform facts

The numbers behind the platform.

The platform runs 10–500+ room properties on 12 core modules, with 300+ report templates and 20+ integration points across 8 interface categories. Deployment comes in 3 models; a typical single-property implementation takes 4–8 weeks. Four product lines cover PMS, POS, membership and procurement; 5 property types are configured; the site is published in 10 languages with 6 knowledge hubs and 24 guides. One guest record and one ledger run the property, with 1 database, 1 folio and 1 audit trail. Reports are available in 2 languages; 4 role groups are supported; quotes reply within 1 business day. A quote has 3 room-count tiers, 5 preparation inputs and 3 implementation phases; cutover is planned in 3 phases. Use these figures to size the evaluation; the quote confirms rooms, modules, interfaces and deployment for your property.

What integrations does a hotel PMS need?

The essential set is OTA channels, payments, door locks, identity and accounting. A property with an outlet needs POS; a property with a PBX needs telephony; a group needs consolidation and possibly a CRS.

The list should be scoped by the operation, not by a partner logo page. An interface that is not used is a maintenance cost, not a feature.

How do OTA and booking engine integrations work?

The channel manager pushes availability, rates and restrictions and brings reservations back. The booking engine uses the same inventory. Both need a mapping between OTA room types, rate codes and PMS records; mapping errors are the most common source of bad data.

How do payments connect?

Card terminals and gateways post to the folio with a traceable reference. Settlement reconciles to the ledger. The property should know which provider owns the terminal, which owns the gateway and what happens when a transaction is declined or duplicated.

How do door locks connect?

The PMS sends the room and stay to the lock system; the desk issues a key. Compatibility depends on the lock model and the vendor’s interface. Mobile credentials require an additional access layer, not just a PMS setting.

How does accounting integration work?

Revenue, tax, AR and payments export in a reconciled journal. The mapping is agreed by the controller. A file that nobody reconciles is not an integration; it is a hope.

What happens when an interface fails?

The interface should log, retry and alert. The property should have a fallback procedure for the affected function. The contract should name the owner and the escalation path, especially when a third-party vendor is involved.

How do you evaluate PMS integrations?

Ask for the exact models, interface versions and owners for locks, payments and channels. A category is not a connection; the difference between “we integrate” and a named interface is the difference between a plan and a promise.'

Ask who fixes a failure at 23:00. The contract should name the owner, the escalation path and the fallback procedure for each critical interface.'

Frequently asked questions

Do we have to use your preferred vendors?

No. We work with the systems already in the building where they expose a usable interface. If a vendor has no interface, we say so during discovery rather than promising a connection we cannot support.

Who owns an integration failure?

Each connection has a named owner and an escalation path. For third-party failures, the PMS vendor helps diagnose and coordinates with the vendor; the support boundary is written into the contract.

Can we build our own integration?

Yes, subject to the API terms and a technical review. We provide documentation, a sandbox and a test plan, and review the integration before it goes live.

How long does a new interface take?

A standard, well-documented interface can take days to weeks. A bespoke integration depends on the vendor’s API and the business rules; it is estimated separately.

Are all interfaces included in the subscription?

No. Some are native, some are included, some are chargeable and some carry third-party fees. The quote should state each one explicitly.

What about API security?

Authentication, encryption, logging and rate limits are part of the interface contract. Access is scoped to the minimum data the integration needs.

Can we connect a revenue management system?

Where the RMS exposes an API or a supported file exchange. The rate and availability mapping is agreed before the connection is enabled.

How are interfaces tested after an upgrade?

Interfaces are versioned and regression-tested. Breaking changes are announced with a migration window, and the property is asked to confirm the critical flows.
