If your store is busy but your bank balance is flat, this is a cash timing problem, not just a sales problem.
Most independent operators do not fail because they miss one monthly report. They fail because they discover cash pressure two weeks too late.
Quick Take
- In the U.S. CPI release published on February 13, 2026, food away from home was up 4.0% year over year.
- In NFIB’s January 2026 survey (published February 10, 2026), a net 32% of owners planned price increases.
- In the 2025 Fed Small Business Credit Survey report, 77% of firms reported higher operating expenses, and 51% reported uneven cash flow.
- A 13-week rolling forecast is the simplest way to see cash gaps before they become emergencies.
Why Monthly P&L Is Not Enough
P&L answers: “Did we make money?” Cash flow answers: “Can we pay next Friday?”
You need both. But if payroll hits this week and receivables arrive next week, profit alone will not protect cash.
The 13-Week Structure
Build one sheet with weekly columns and these rows:
Cash in
- in-store collections
- third-party payouts (net)
- catering/preorder deposits collected
- other inflows
Cash out
- food and beverage purchases
- payroll and payroll taxes
- rent and occupancy
- utilities and software
- debt service
- tax payments
- owner draw/distribution
Net and runway
Weekly net cash = Total cash in - Total cash out
Ending cash = Beginning cash + Weekly net cash
Runway (weeks) = Ending cash / Average weekly cash out15-Minute Setup Example
Assume:
- beginning cash: $38,000
- average weekly cash in: $26,500
- average weekly cash out: $27,900
Weekly net cash = 26,500 - 27,900 = -1,400If nothing changes:
Runway = 38,000 / 27,900 = 1.36 weeks of outflow coverageThat is a warning. You need action before week 3, not at month-end close.
Decision Triggers (Use These)
Set clear trigger rules:
- runway < 4 weeks -> freeze nonessential spending
- two negative weeks in a row -> pause low-margin promos
- food purchase spike > 8% week-over-week -> re-cost top 15 SKUs
- labor cash-out above target band -> adjust schedule mix this week
Without trigger rules, the forecast becomes a passive report.
Common Cash Leaks Owners Miss
- delivery/promo deductions hidden inside net payouts
- owner draw timing not aligned with cash seasonality
- supplier pre-buys without corresponding sales plan
- weekly tax set-aside skipped during high-volume weeks
Each leak looks small. Together they kill cushion.
Weekly Owner Routine (30 Minutes)
- Post actuals for last week
- Re-forecast next 13 weeks
- Check runway and trigger rules
- Choose 1 to 2 actions for this week
- Confirm action owner and due date
This routine is simple on purpose. Complicated models break in real operations.
