Understanding payment terms

Payment terms define when a client must pay an invoice. They are usually written as "Net X", where X is the number of days from the invoice date. Clear terms reduce disputes and help you forecast cash flow.

  • Due on receipt - payment expected immediately
  • Net 7 / Net 15 - common for freelancers
  • Net 30 - a standard business term
  • Net 45 / Net 60 - often used by larger companies

Tips for getting paid on time

  • State the due date clearly on every invoice
  • Offer convenient payment methods such as bank transfer or PayPal
  • Send a friendly reminder a few days before the due date
  • If an invoice becomes overdue, follow up with a payment reminder
