Where the money goes
Three Things To Do This Week
Ranked by impact on the danger week
1
DO TODAY
Chase invoice INV-2247, Oakley Developments
£8,420 outstanding, 41 days overdue. They paid the last invoice on the 43rd day after a phone chase. This is your single biggest cash drag. A polite call to Sarah in accounts (you have her direct line) typically clears it within 5 working days.

BY FRIDAY
Move £4,240 into the VAT savings account
You're £4,240 short on the Q2 VAT bill due 7 Aug. The danger week dip is largely VAT-driven. Standing order of £1,060/wk for 4 weeks from current to savings clears it without breaking a sweat, and stops the August bill becoming a panic.

THIS MONTH
Renegotiate Travis Perkins to 30-day terms
You currently pay Travis Perkins on 14-day terms, roughly £4,800/month in materials. Moving to 30 days (standard for your tier) frees up £2,560 of working capital permanently. They offered it last year. Take the offer.
