Cash Flow Management for Small Service Businesses
How small service businesses keep cash flow healthy through invoicing cadence, deposits, payment terms, and expense discipline.
Key takeaway
Healthy cash flow comes from invoicing weekly (not monthly), taking deposits, using Net 7/14 terms, and keeping a 2–4 week expense buffer.
Cash flow is the variable that determines whether a profitable business stays in business. Profit on paper does not pay rent.
Invoice on a tight cadence
Bill weekly, not monthly. The shorter the loop between work and invoice, the shorter the loop between work and cash. QuickBill's mobile workflow makes weekly billing feel as light as monthly billing used to.
Take deposits
For any engagement over $1,000, take a deposit at signing. 50% is standard for project work; 25% is standard for retainers.
Net 7 or Net 14
Default to short payment terms. The clients who can pay quickly will; the ones who can't will tell you, and you can negotiate.
Maintain a buffer
Keep at least 2–4 weeks of operating expenses in cash. This converts a slow-pay month from an emergency to a non-event.
