Frequently Asked Questions

How should I number invoices?

Use a sequential scheme such as INV-0001, INV-0002. Never reuse a number — it keeps your records and taxes clean.

What payment terms should I set?

Net 14 or Net 30 are common. Shorter terms get you paid faster. State the due date and any late fee clearly on the invoice.
