Cash Flow Management for Small Businesses: A Founder’s Playbook

Make a 13-week view of cash

Start with bank balances. Estimate weekly collections, payroll, vendor payments, rent, taxes, loan obligations and committed capital expenditure. Record expected cash movement, not just billed revenue.

Maintain a base case and a cautious case that assumes delayed collections or weaker sales. Review the forecast every week and keep notes about the largest changes.

Measure the cash conversion cycle

Identify how long inventory sits, how many days customers take to pay and how quickly suppliers must be paid. An increase in sales may absorb cash if inventory and receivables rise faster than collections.

Even service firms should monitor unbilled work, customer acceptance milestones and outstanding invoices.

Shorten collections without damaging relationships

Set clear payment milestones before starting work. Invoice promptly, follow up consistently and make it easy to pay. Prioritize overdue accounts by size, probability of collection and relationship sensitivity.

Offer early payment incentives only after calculating whether the discount is cheaper than the working-capital burden it removes.

Plan spending around real receipts

Tie new hires, campaign budgets and inventory purchases to confirmed milestones. Separate essential operating payments from discretionary bets, and specify who approves unplanned expenses.

A reserve policy should reflect volatility, not an arbitrary number copied from another business.

Use financing as a tool, not a substitute for economics

Working-capital facilities can bridge timing gaps, but interest, fees, covenants and repayment schedules matter. Review options with qualified financial professionals and avoid depending on refinancing to cover structurally unprofitable operations.
