Put the buying calendar beside the sales calendar
List committed supplier deposits, production balances and expected delivery costs by payment date. Compare them with expected receipts. Keep possible future buys separate from orders you have already committed to.
Follow a sale through to the bank
An online order, a platform settlement and the bank receipt are different records. Fees, refunds and timing differences need reconciling. Wholesale adds another timetable: the invoice date does not guarantee the date the customer will pay.
Leave room for what comes back
Review the timing and value of returns using your own trading information. Do not assume every sale in a strong month stays sold. Agree how refunds and their timing enter the forecast, and review the assumption as actual information arrives.
Look at stock that is not moving
Ageing stock ties up cash and can make future discounting more likely. A stock report should support a conversation about what to reorder, what to hold and what needs a different plan. The finance team and buying team need the same definitions.
Test the next decision
Run the forecast with the proposed order included, then test a plausible delay in receipts or stock delivery. The point is to see what the business would need to do if the timing changes. It is a planning exercise, not a prediction.
Where to start
A useful starting pack is your buying commitments, aged customer balances, stock report and sales-channel settlements. Together they explain more than the revenue line alone.
