Cash Flow Forecast
A projection of the cash coming into and going out of your business over the coming weeks or months.
Definition
A cash flow forecast is a forward-looking projection of the money expected to move in and out of your business over the coming weeks or months. It starts with your current bank balance, adds expected inflows (invoice payments, retainers, deposits) week by week, subtracts expected outflows (payroll, rent, subcontractors, taxes, subscriptions), and shows the projected balance at each point. The output is simple: a line that either stays above zero or does not.
The craft is in the timing assumptions. Revenue on your books is not cash in your account—an invoice sent today on Net 30 terms to a client who habitually pays ten days late is a cash inflow in about 40 days, not now. Good forecasts use realistic payment timing from your actual receivables history, include lumpy items like quarterly tax payments and annual renewals, and get updated weekly as invoices are sent and paid. A 13-week rolling forecast is the common standard because it is long enough to act on and short enough to be accurate.
Why It Matters
Profitable businesses fail from cash gaps, not losses—a great quarter on paper does not make payroll if the cash arrives six weeks after the salaries are due. A forecast converts that risk from a surprise into a scheduled problem: seeing a projected shortfall five weeks out gives you time to chase receivables, delay a purchase, push a client deposit, or draw on a credit line calmly instead of at panic prices.
It also upgrades your decisions. Hiring, taking on a big project with heavy upfront costs, or buying equipment all look different when you can see their cash impact plotted against the next quarter. Freelancers and agencies with irregular project income arguably need this more than anyone—the forecast is what tells you whether a slow sales month is survivable or an emergency.
Examples
- 1
An agency's 13-week forecast shows the balance dipping to -$4,000 in week 7 due to a quarterly tax payment, so it accelerates two invoices and delays a hire.
- 2
A freelancer maps $18,000 of outstanding invoices against actual client payment habits and sees only $7,000 will likely arrive before rent is due.
- 3
A studio updates its forecast every Monday in 30 minutes, catching a client's missed $6,500 payment within days instead of at month-end.
