How to write a web developer invoice
- Invoice by milestone on bigger builds, so you are paid as the work progresses.
- Bill change requests separately, referencing the request and who approved it.
- Put recurring hosting and maintenance on its own line each month.
- Keep domain and hosting costs you pay for the client on separate lines.

What an invoice must include in the US
- There is no federal law that sets the contents of a commercial invoice between US businesses.
- Good practice: seller name and contact details, buyer name, invoice number, invoice date, description of goods or services, quantities and prices, total due, payment terms and due date.
- Where a sale is subject to state or local sales tax, show the tax separately as your state requires.
- Some states and industries add their own rules (for example sales tax display rules, or contractor licence numbers on construction invoices).
Invoice rules in the US at a glance
- Tax
- Sales tax (state and local). See sales tax by state
- Tax number
- No federal invoice tax ID requirement. Many businesses show an EIN or a state sales tax permit number, but no federal law requires it on an invoice.
- Not registered for tax
- Sales tax is set by each state, not federally (there is no national sales tax or VAT). A seller that does not hold a sales tax permit in a state, or whose sale is not taxable there, must not add sales tax to the invoice.
- Small invoices
- No federal simplified invoice rule exists because there is no federal invoice law.
- Payment terms
- No statutory default for private B2B invoices; the agreed terms apply (Net 30 is common practice, not law).
- Late payment
- No general statutory late payment interest for business-to-business invoices. Late fees and interest are what the contract or invoice terms say, limited by each state's usury and late charge laws. Courts may award pre-judgment interest at a state rate.
- Keep records
- IRS guidance: generally 3 years after filing the return the records support; 6 years if income was under-reported by more than 25 percent; 7 years for bad debt or worthless securities claims; employment tax records at least 4 years. States may require longer for sales tax.
