12-month cash planning
Build a cashflow forecast that shows when the squeeze happens.
A profitable year can still contain a difficult month. Put collections, operating cash, equipment, reserves, and owner withdrawals on a calendar so timing becomes visible before the bank balance makes the decision for you.
Profit explains whether the work creates value. Cashflow explains whether the business can pay what is due when it is due. An owner needs both views.
A forecast does not predict the future. It makes your current assumptions visible enough to challenge, revise, and compare with what actually happens.
Keep profitability and cash timing separate.
A booked job, a completed job, an invoice, a card collection, and an available payout can happen on different days. Equipment may be paid now and support work for years. An annual policy may leave one month even though you evaluate prices every week.
That equation is intentionally simple. It does not replace an income statement or professional accounting advice. It gives the owner a direct view of liquidity.
Begin with cash you can verify.
Enter the opening business cash balance for the first forecast month. Then place customer collections in the month you reasonably expect the funds to become available—not merely when the work is quoted.
- Completed and paid work: use the actual available amount after payment fees.
- Booked work: keep it as a forecast assumption until it is completed and collected.
- Unbooked capacity: do not record it as revenue. Model it only inside a clearly labeled scenario.
- Deposits and refunds: place cash in the month it moves and keep the related obligation visible.
Place irregular costs where they land.
Monthly averages are useful for pricing, but cash planning must also show the actual payment month. Put equipment purchases, repairs, annual policies, registrations, software renewals, training, and seasonal supplies where you expect to pay them.
If you include a tax reserve, make it an owner- or professional-supplied assumption. This guide does not determine tax liability or replace accounting, tax, or legal advice.
Use three scenarios to expose fragile assumptions.
Start with a base case you can explain. Then create a downside case with fewer collected jobs, slower payment, or a cost shock. Add an upside case only when you also model the extra supplies, payment fees, hours, and capacity required.
The purpose is not to select the most exciting total. Look for the first month where ending cash falls below the buffer you decided to protect. That date creates time to adjust price, spending, capacity, collections, or owner withdrawals.
Roll the forecast forward every month.
- Lock the completed month and replace forecasts with actual collections and payments.
- Explain the largest gaps without rewriting the original plan.
- Carry actual ending cash into the next month as opening cash.
- Update future assumptions only when new evidence supports the change.
- Write one decision rule, such as delaying an equipment purchase if the downside buffer is crossed.
A forecast earns its place when it changes a decision early. Keep the model understandable enough that you can explain every number without trusting a black box.
