Keep confirmed amounts and uncertain estimates separate, and update the forecast as payments actually arrive.
A practical step-by-step approach
Start with your current available cash
Use balances you have verified and keep each currency separate unless you have an appropriate conversion basis.
List expected inflows
Include likely customer payments by expected date. Label uncertain items rather than treating every unpaid invoice as cash already available.
List scheduled outflows
Include payroll, supplier bills, rent and known recurring costs for the same period.
Identify the tightest week
Compare each week’s expected inflows and outflows to find periods where cash could be short.
Update it with actual payments
Adjust the plan when invoices are paid or expenses change. Review it weekly or more often when cash is tight.
Your working checklist
- Verified starting balances
- Expected payment dates
- Known bills and fixed costs
- Separate uncertain estimates
- Weekly update routine
Treating overdue invoices as guaranteed future cash can make a forecast appear healthier than it is.
Common questions
How far ahead should I plan?
A rolling four-to-eight-week view is a useful starting point for many small teams, then adapt to your own payment cycle.
What about multiple currencies?
Track them separately and document any exchange-rate assumptions; do not merge unlike amounts without explaining the conversion.
