Small Business Invoicing FAQs
What information must a small business invoice include?
At minimum: your business name and contact details, the client's name and address, a unique invoice number, the invoice date, payment due date, a description of goods or services with quantities and prices, any applicable tax, and the total amount due. Including your business registration number builds additional trust.
How do I choose payment terms for my small business invoices?
Net 30 (payment due in 30 days) is the standard for B2B invoicing. For smaller jobs or new clients, Net 14 or Net 15 improves your cash flow. For large projects, consider 50% upfront and 50% on completion. Always state your payment terms clearly on every invoice.
Do I need invoicing software, or can I use a free invoice generator?
For most small businesses, a free invoice generator is sufficient. Dedicated accounting software makes sense once you need bank reconciliation, payroll, or financial reporting. Zap Bill creates professional PDF invoices for free — no monthly subscription until you need more than 3 invoices a month.
How long should I keep copies of my invoices?
Tax authorities in most countries require you to keep business records for 5–7 years. In the US, the IRS recommends at least 3 years but 7 years is safer. In the UK, HMRC requires 6 years. Store PDF copies of all invoices — both sent and received.
Can I add a late payment fee to my invoices?
Yes, but you must state it in your payment terms for it to be enforceable. A common rate is 1.5% per month on the outstanding balance. Add a note like "Invoices unpaid after 30 days are subject to a 1.5% monthly late payment fee" to your invoice terms.
