Stage Payment Software for UK Contractors

Software that connects the payment plan to delivery. In Archdesk the contract value breaks into payment stages tied to the schedule milestones that trigger them, the invoice generates the day a milestone completes with evidence attached, and every job shows what is due, invoiced and late on one screen.

A milestone definition wizard sets each milestone with clear completion criteria, and the contract value is broken into stages linked to them: deposit, interim stages and completion. Retention is calculated automatically against the agreed stage values.

The day the milestone is verified complete. The invoice generates itself with the completion evidence attached, routes through approval workflows, and is tracked from issue to payment. Billing happens when the work finishes, not when the office finds out at month-end.

The cash flow forecast is built from the stages still to come, so it moves when the plan does. Completion forecasting and earned value analysis show how the remaining stages will land, and budget against payment sits on one dashboard per job.

Yes. One view shows milestone status across every job: what is complete, what is invoiced and what is still to come, with the full payment history logged behind each figure.

In UK practice, paying a subcontractor runs on the application and certification cycle: a payment notice sets out what will be paid, a pay less notice any difference, and retention is held and released under the subcontract. Invoices, approvals and payment records live on the same project record in Archdesk, so the paper trail sits with the milestone it pays for.

Retention is calculated against the agreed stage values and tracked per subcontract alongside the rest of the payment record, so balances and release timing stay visible long after practical completion. Release stops depending on someone remembering to chase it at the end of the defects period.

Yes. Applications for payment run in the platform against the same stage records the invoices and retention read from, and they route through approval workflows, so the applied position and the invoiced position always agree with each other.

Yes. Archdesk is a certified Xero partner and integrates with Sage, so stage invoices raised in the platform and the ledger stay in step without re-keying, and finance keeps its own system.

Yes. One view shows every live job with what is due, what is invoiced and what is late, and reporting runs at project and portfolio level from the same records, so the order book reads from one set of live numbers.
