Small Business Invoicing Guide: Process, Terms and Cash Flow
Build a repeatable invoicing process for your small business: numbering, approvals, terms, reminders and reconciliation.
Design the process, not just the document
Most small businesses have a template but no process. Decide who raises invoices, when they go out (weekly batch beats ad hoc), who chases, and where the PDFs are stored.
Numbering and records
Use a year-prefixed sequential number and never reuse one. Store a PDF of every invoice in a single folder structure by year and client.
Choosing payment terms
| Terms | Meaning | Best for |
|---|---|---|
| Due on receipt | Pay immediately | New or one-off clients |
| Net 14 | Within 14 days | Small businesses, freelancers |
| Net 30 | Within 30 days | Corporate clients |
| 2/10 Net 30 | 2% discount if paid in 10 days | Encouraging early payment |
Reconciliation
Match every incoming payment to an invoice number weekly. Unmatched payments are how businesses accidentally chase clients who already paid.
Cash-flow tips
- Invoice on delivery, not at month end.
- Split large projects into milestones.
- Charge late interest — and mention it before you need it.
