Everything a subby needs
between winning the job and being paid in full.
SubbyWise covers the whole lifecycle — setting the site up, claiming, chasing, reconciling, and closing the final account. Here's what's in it.
Build the application, not the spreadsheet.
The payment matrix is the heart of it — plots down the side, stages across the top, and everything else flows from what you tick.
Payment Matrix Editor
A familiar Excel-style grid. Assign house types to auto-populate hundreds of plots at once, adjust individual cells, and export the breakdown to send straight to the client.
Punch-Style Booking
When it's time to claim, click stages complete, adjust percentages, and generate the application in a few clicks. Nothing can be booked below what's already been claimed.
Bill of Quantities
Not a plot-and-stage job? Build a full BQ with sections and subsections, claim against quantities and percentages, and produce a BQ application pack instead.
Application Register
Every application in one register — draft, submitted, certified, paid — with what's outstanding on each and which documents belong to it.
Find out where the money actually went.
A lump sum landing in the bank tells you nothing. SubbyWise breaks it down to the plot and the stage it paid for.
Stage-Level Payment Tracking
Payments allocated to individual unit and stage. "Plot 3, 1st Fix = £14,580 received" — not a guess against a total.
Remittance Reconciliation
Match a remittance to the stages it covers using a visual picker, with the client’s own remittance PDF open beside it. Underpayments and overpayments flagged automatically.
Payment Variance
Claimed vs paid, stage by stage, every line marked Matched, Underpaid, Overpaid or Pending — so a shortfall conversation starts with a document, not a feeling.
Retention Tracker
Retention held per valuation, first and second release positions tracked, and alerts as practical completion approaches so nothing is quietly left behind.
Set your rules once. Every figure follows them.
CIS, VAT, retention and price protection are configured per project in a guided wizard — then applied to every application, invoice and report without you doing the sums.
CIS With A Materials Split
Deduct on labour only. Materials are recorded against the application and taken out of the CIS base — plus CIS handled correctly on retention release, when the money finally comes back.
VAT & Domestic Reverse Charge
Reverse charge on by project, with the right wording on the invoice. Variations and customer upgrades can carry their own VAT treatment when they are billed differently.
Retention Rules That Match The Contract
Rate, cap by value or percentage, release strategy, and a separate retention rule for variations where your contract treats them differently.
Fixed Price & Price Hold
Record the fixed-price period from the contract date, get warned before it expires, and review price-hold positions in a register instead of discovering it too late.
JCT Payment Cycle Awareness
Submission cut-off day, payment terms in days, due dates and final dates for payment calculated from the cycle you set — plus defects liability and PO requirements.
Built For How Housebuilders Pay
Taylor Wimpey, Barratt, Persimmon, Bellway — the whole housebuilder payment cycle is modelled. Setting up a job is picking your numbers, not bending the software round them.
Everything that is not the main application.
Variations, contra charges and customer upgrades tracked separately, with their own approval trail — so extras never get quietly mixed into a standard claim.
Variations
Raise, price and track variations with approval statuses and their own reference numbers. Claim them on an application or bill them separately.
Contra Charges
Record what the contractor is charging back, against which project, and see the effect on your position before it lands as a surprise on a remittance.
Customer Upgrades
Plot-by-plot upgrade work with its own price list, invoices, tracking report and a site checklist for the lads — kept apart from the main contract account.
Your accountant gets the figures without retyping them.
Export what you have billed into your accounts package, or hand your accountant a clean CSV. Set the codes once and forget about it.
Sage 50, Xero & QuickBooks Export
Pick the format, pick the period, download the file. Nominal codes and tax codes — including the domestic reverse charge codes for each package — are mapped once in settings.
Accountant CSV
Not on any of the big three? A plain CSV your accountant can open anywhere, encoded so Excel doesn't mangle it.
Export History
Every export recorded with what it contained, so an invoice cannot quietly go across twice. Re-export deliberately, never by accident.
Quick Invoices
One-off invoices outside a project — day works, small jobs, materials — with a saved client address book you can import from your accounts package.
Sales Ledger
What has been invoiced, what has been paid, and what is still out — across every project and every client in one view.
Let people in without handing over the keys.
Different people need different slices of the account. Nobody sees more of your money than they should.
External QS Access
Using a freelance QS for your valuations? Give them their own login. They prepare and submit inside the system, so you see exactly what was sent, when, and when payment is due.
Field Users
Site staff get a separate login with access to the projects you choose. They assess and submit — they can't see applications, invoices or any financial figure.
Multi-Company Support
Run more than one trading company? Keep them completely separate, each with its own branding, settings, numbering and data — under one account.
The boring bits that matter at 4pm on a Friday.
It's your whole commercial position in one system. It should be hard to break and easy to undo.
Recycle Bin & Recovery
Deleted something you needed? It goes to a recycle bin, not into thin air. Application lifecycles are protected so a certified claim cannot be casually unpicked.
Integrity Checks
Nightly verification that the figures across applications, payments and ledgers still agree — flagged in the app rather than found by an accountant in March.
Notifications
A notification bell for overdue applications, submission cut-offs approaching, retention releases due and compliance about to expire.
23 documents, all on your headed paper.
Every one generated in seconds, as PDF or Excel, with your logo, address, company number and VAT number already on it. Several — like the QS valuation worksheet — come with editable columns so the QS just fills in their figures and sends it back.
There's a compliance side to this too.
Insurance, SSIP accreditations, CSCS cards and training tickets — tracked, alerted before they expire, and packaged up for whoever is asking.
