Seasonal cash flow: build a calendar around the lowest balance
By CFO Index · Published
A busy season does not necessarily pay for itself before the bills arrive. Stock, staffing and launch costs may fall before collections, while refunds and other commitments continue after sales slow. Ask your fractional CFO for the dates of the lowest usable balances, not just a profitable season or a positive year-end forecast.
Start before the first commitment and finish after the last obligation
Choose a horizon that includes preparation, the selling season and the quieter period that follows. Extend it if the next season's deposits arrive before the previous cycle has fully unwound. British Business Bank's seasonality guidance recommends mapping income and costs and forecasting opening balances, receipts, outgoings and closing balances on a monthly or weekly basis. Use your own operating calendar; a retail holiday peak and a summer services business do not share the same cash pattern.
Date cash movements, not just sales activity
Separate orders, delivery, invoices and expected bank receipts. For each payment, record its due date, amount, evidence, owner and whether the commitment is already binding or still optional. Include the actual schedules for payroll, rent, tax, freight, software renewals and customer refunds where relevant. Confirm tax and employment obligations with the appropriate adviser. Do not assume a liability can be delayed merely because it falls in the quiet season.
Read the whole cycle before interpreting the peak
The following hypothetical six-month schedule uses €80,000 of opening usable cash and invented receipts and payments. It excludes financing and assumes all relevant payments for this simplified example are in the table. It is not a complete budget or a recommendation for cash reserves.
| Month | Opening cash | Receipts | Payments | Closing cash |
|---|---|---|---|---|
| September: preparation | 80 | 20 | 50 | 50 |
| October: pre-season commitments | 50 | 10 | 55 | 5 |
| November: early peak | 5 | 90 | 60 | 35 |
| December: peak collections | 35 | 140 | 75 | 100 |
| January: quieter trading | 100 | 15 | 55 | 60 |
| February: continuing obligations | 60 | 10 | 40 | 30 |
A positive month-end balance can hide an unpaid bill
In that example, October starts with €50,000. Suppose €40,000 is paid on 3 October and €15,000 on 8 October, before the €10,000 receipt on 20 October. Cash falls to minus €5,000 on 8 October, despite ending the month at plus €5,000. That negative balance is an unfunded requirement, not permission to make an impossible payment. Break the tight period into dated movements and retain the sequence; a monthly average will not reveal this problem.
Do not spend the peak balance twice
The December closing balance of €100,000 is followed by €70,000 of net outflows across January and February, leaving €30,000. It is not all spare cash. Across the full example, receipts total €285,000 and payments €335,000, reducing opening cash by €50,000. Cash movement is not profit: stock, deposits and timing differences may have different accounting effects. Keep restricted balances separate and add any omitted obligations before making a distribution or expansion decision.
Test a weaker season and a later season separately
First move collection dates without changing total demand. Then test lower demand with the payment commitments that would genuinely remain. In a separate hypothetical downside to the table, December collections are €40,000 lower and all payments stay fixed. December closes at €60,000, January at €20,000 and February at minus €10,000. This exposes a post-season gap as well as the existing October timing gap. If refunds, variable costs or cancellations would change too, model those explicitly rather than applying an unsupported blanket saving.
Work backwards from the last useful decision date
Assign a decision deadline before each optional commitment: order quantity, temporary capacity or promotional spending. Check whether a smaller order, agreed supplier terms or different launch timing is operationally possible. Any funding option needs separate confirmation of availability, conditions and costs; an undrawn or unapproved facility is not cash. Record proposed actions separately from confirmed changes, and rerun the calendar after approval.
Close the season with evidence for the next one
Compare the dated forecast with actual collections and payments. Identify which differences came from demand, returns, settlement timing or unexpected commitments. Retain those explanations for the next cycle instead of copying this year's monthly shape unchanged. A useful recurring CFO deliverable is a maintained calendar, a list of upcoming decisions and an explanation of the lowest balance before and after confirmed actions.
