For builders
Bookkeeping for builders — without the site-office shoebox
14 days free · no card required · sign-up takes about 60 seconds on WhatsApp.
Made for your trade
Your books, kept from the van
Extensions, footings, renovations — a builder's month is a blizzard of merchant receipts, plant hire invoices and part payments. SubReady catches it all through WhatsApp: photo the Travis Perkins receipt, forward the digger-hire invoice, log the day-rate payment, and every cost lands against the right job. You see what each job actually made, not what you hope it made.

Expenses builders should never miss
Building work has more claimable costs than almost any trade. Keep every one of these:
- Materials — timber, aggregates, blocks, fixings, sealants
- Plant and tool hire — diggers, dumpers, mixers, breakers
- Skip hire and waste disposal per job
- Subcontracted labour you paid out
- Van/truck costs, fuel and mileage between sites
- Insurance, scaffold tickets, CSCS renewals
- Small tools, blades, PPE and workwear
CIS, handled
CIS for builders
Builders often sit on both sides of CIS — deducted as a subcontractor on some jobs, engaging subbies on others. SubReady tracks deductions taken from you at 20%/30%/gross from the CIS statements you forward, splits labour and materials properly on your invoices, and keeps the records that decide your refund.
