For subcontractors
The monthly application, minus the spreadsheet.
A subcontractor's key to compliant, professional and effortless applications.
Enter percentage complete once. SubbyApps recalculates cumulative claim, retention and nett amount — then generates a submission-ready PDF, every valuation date.

Every trade on site
Whatever your trade, it's the same application.
Pick a trade to see how its work looks as a line item — the same value, percentage and claim maths behind every application on SubbyApps.

The problem
Right now, that application lives in six places.
A spreadsheet per subcontractor. A photo of a hand-filled form sent over WhatsApp. Retention recalculated by hand, again. Nobody is sure which file is the real one — and the valuation date doesn't wait.
One application. One place it lives.
The monthly cycle
Same four steps, every valuation date.
1 / 4
Project set up
SubbyApps will tailor your application to suit your needs and contract requirements.

Each subcontractor's team logs how much of their own work is complete this period.

Numbers recalculate
Cumulative claim, retention and nett amount update instantly — no formulas to check.
4 / 4
PDF generated
A submission-ready application is produced automatically, branded and ready to send.

What it does
Everything the application needs, nothing it doesn't.
Recurring valuation dates
Monthly, weekly, biweekly, or ad hoc — the next application date is worked out for you.
Revisions, not overwrites
Re-issue an application within the same period without losing the original submission.
Retention handled
Set the percentage once. Every application applies it correctly, every time.
Branded PDF output
Your company logo and bank details, laid out to match the paperwork you already submit.
One place, not a shared inbox
Every application lives against your project — never buried in someone else's email or a shared spreadsheet.
Scoped access
Staff see only the projects they're assigned to — nothing else.
On the roadmap
Coming soonVAT, CIS and tax — presented correctly, not worked out by hand.
We're building CIS deduction and VAT handling directly into every application, so a subcontractor's paperwork is compliant by default rather than something bolted on afterwards.
CIS deductions, shown automatically
The correct Construction Industry Scheme deduction calculated and broken out on every application — not worked out separately and pasted in.
VAT treatment per application
Standard rate, zero-rated or the domestic reverse charge — set once per project, applied consistently every time.
One document, one number
Gross claim, CIS deduction, VAT and nett payable, all on the same PDF a main contractor already receives.
