Invoicing
Invoicing is one of the most underestimated parts of running a small business. A poorly written invoice can stall payment for weeks, trigger disputes, or quietly lose you margin to fees and tax mistakes. This hub covers what to include, how to set due dates, and how to follow up without damaging the relationship.
Invoicing essentials
Why invoice quality decides how fast you get paid
Most small-business cashflow problems start on the invoice itself — unclear line items, vague terms, or a missing due date.

How small invoice errors turn into cashflow problems
A missing field or a vague line item rarely causes a single invoice to fail. It causes weeks of delay across many invoices — and that is what becomes a cashflow problem.
Why clear invoices get paid faster
Clarity is not a design preference. It is the variable that most reliably shortens the time between sending an invoice and receiving the money.

Common questions
- What must a professional invoice include?
- Your business name and contact details, the customer's, a unique invoice number, issue and due dates, an itemised description, applicable tax, and clear payment instructions. See the professional invoice guide for the full checklist.
- What payment terms should I use?
- Net 14 is a sensible default for most B2B work, Net 7 for new customers, and due-on-receipt for B2C. Whatever you choose, state it on the invoice and in the original quote so it never feels like a surprise.
- How do I chase a late invoice without being aggressive?
- Use a calm, predictable cadence: a friendly reminder on day 1 overdue, a firm reminder around day 7, and a final notice around day 14 before switching channels. The Late Payment Recovery tool generates the drafts.
