Cash flow is the first survival metric for any SMME. Profit can look healthy on paper while the bank balance tells a different story. If you watch a short set of numbers every week, you can spot pressure early, make faster decisions, and avoid last minute borrowing, missed payroll, or overdue tax payments.
Here are the 7 numbers every SMME should review weekly, in this order:
If you only have time for one view, calculate this weekly: starting bank balance plus expected cash in minus committed cash out. This is your near term cash position, and it is the clearest early warning signal.
1) Bank balance, what is available today
This is the reality check. Use the cleared bank balance, not what you think should be there. If you have more than one account, add them together. Include access to overdraft only if it is approved and available. A weekly habit of reconciling the bank to your bookkeeping prevents small errors from becoming large surprises.
2) Cash in expected for the next 7 days
This is not total invoices issued, it is the cash you expect to collect. Use evidence, promised payment dates, debit order schedules, and past payment behaviour by customer. Be conservative. If a customer is often late, move the expected receipt to a later week. The goal is a forecast you can trust, not an optimistic one.
3) Cash out committed for the next 7 days
Committed means you cannot easily avoid it without causing harm, payroll, PAYE or statutory payments, rent, critical suppliers, loan repayments, insurance, and essential logistics. Separate nice to have spend from must pay spend. When cash is tight, this single number helps you decide what to pause, renegotiate, or split into smaller payments.
4) Net cash movement for the week
Calculate: expected cash in minus committed cash out. If it is negative, you have a funding gap. You can then choose the least expensive fix, collect faster, delay non essential spend, negotiate supplier terms, run a targeted promotion with quick payment, or arrange short term finance before it becomes urgent.
5) Debtors aging and total overdue
Break receivables into current, 30 days, 60 days, and 90 plus. The single most important figure is total overdue. Overdue debtors are not just an accounting issue, they are trapped cash. Each week, identify the top five overdue accounts by value, assign an owner to follow up, and agree on a next action and date. Consistent follow up beats occasional aggressive chasing.
6) Gross margin percentage
Cash flow problems often start with pricing and cost leakage. Gross margin is sales minus direct costs, divided by sales. Watch it weekly, especially if you sell products with changing input costs or you use subcontractors. A small margin drop can wipe out cash quickly. If margin falls, investigate pricing, discounts, wastage, stock shrinkage, and unbillable time.
7) Cash runway
Runway tells you how long you can operate if collections slow. A practical weekly version is: cash available divided by average weekly cash out. If your runway is only a few weeks, you need to act early. Extend customer payment terms only with care, and avoid taking on commitments that lock in future cash outflows.
