Most small-shop budgets fail for one reason: they are built once and never touched again. Sales shift, suppliers move prices, a quiet month arrives — and the plan on the spreadsheet stops matching the till. The fix is a plan you revisit in minutes, not a document you dread.
Start from zero, not last year
List what the shop truly needs next month: rent, wages, stock, utilities, loan payments. Then add one line for growth — a small repair fund or a marketing pot. Everything else must earn its place. Owners tell us this single reset cuts 8–12% of drift spending in the first pass.
Run a rolling three-month outlook
Keep three columns: this month firm, next month likely, third month rough. Every Friday, roll them forward by one week. You will spot a thin month while there is still time to trim orders or chase invoices, instead of discovering it on payday.
- 1. Split takings on arrival: 60% running costs, 20% wages, 10% tax pot, 10% buffer.
- 2. Cap discretionary spend per person so approvals stay quick.
- 3. Review supplier deals quarterly — the leak usually hides there.
Make Friday the money day
Fifteen minutes: snap receipts, match the week's sales, glance at the three-month view. Our Friday tidy habit shows the exact routine. Pair it with monthly bookkeeping and the plan almost runs itself.
Takeaway
A spending plan holds when it is small, weekly and visible. Build from zero, roll three months forward, and split takings before they get spent.
