“Profit disappears” usually starts with messy job costs.
This is our 15-minute weekly cost capture checklist for CIS jobs. Do it before the paper piles up.
✅ Labour: write start to finish hours per person (and any gaps)
✅ Materials: log every delivery and every waste line
✅ Subbies: record invoice date for each subbie (then match it)
✅ Overheads: allocate the ones you always forget
⏰ Then do the 2 quick checks for the profit killers:
🚨 Missing retentions or stage payments that are sitting unclaimed
🚨 CIS deductions or VAT timing that does not match what’s booked
Action win: set a recurring Friday 3-point review in Xero.
Flag jobs where labour and materials are booked but CIS deductions or stage payment claims are still sitting unallocated, then chase the cash before it slips.
