Everything you need to manage construction payments.
Nine tools, one workspace: contracts, applications, notices, payments and the deadlines that connect all of them. Here's exactly what each one does.
Contracts
Set up a contract once — the value, payment terms, retention percentage and CIS status — and everything else in SubPay uses those rules automatically. No re-checking a paper contract every time you raise an application.
Payment Applications
Record what you're claiming for, and SubPay works out retention, CIS deductions and what's actually due — from the numbers you enter, not a spreadsheet formula you have to remember how you built.
Payment Notices
Log every Payment Notice against the application it belongs to, with the exact date it was given. If it's ever questioned later, you've got proof — not a memory of when you sent it.
Pay Less Notices
If a payer intends to pay less than claimed, record the amount, the reason and the date here. SubPay flags the deadline so it's never missed on either side.
Payments
Log every payment as it comes in and watch the outstanding balance update immediately — no manually recalculating what's still owed after each one.
Commercial Ledger
One screen showing what's due, what's been paid, and what's still outstanding — across every contract at once, not just the one you happen to have open.
Notifications
SubPay tells you what needs attention before it becomes urgent: an overdue payment, an approaching notice deadline, retention that should have been released weeks ago.
Activity History
A timeline of everything that's happened on a contract — who did what, and when — so nothing relies on someone remembering a phone call from three weeks ago.
Search
Find any contract, application, notice or payment in seconds, instead of scrolling through folders, spreadsheets or old email threads.

- ✓Payment Notices and Pay Less Notices recorded against the right application.
- ✓A live countdown to each notice deadline, not a date buried in an inbox.
- ✓Log payments received and watch outstanding balances update immediately.
- ✓A full audit trail if an application is ever disputed.
