Use this page to prepare an invoice for a United States customer, vendor, agency, or client with the details needed for payment. For ordinary private-sector business, the United States has no prescribed federal private-sector invoice form. The IRS treats invoices as supporting documents that help show gross receipts, income, and expenses, so the practical goal is a clear business record.
A usable invoice identifies the seller, buyer, invoice date, invoice number, payment terms, line items, amounts, and payment instructions. Add sales tax only when the transaction requires it under the relevant state and local rules. For federal contract work, use the agency's invoice instructions and the FAR proper-invoice fields.
Start with seller and customer names, mailing or billing addresses, invoice date, unique invoice number, due date, and remittance details. Each line item should describe the work or goods, quantity or time, unit price or rate, and extended amount. Service invoices often need project names, service dates, purchase order numbers, or contract references so the customer can match the charge to approval records.
Sales tax belongs on the invoice only when the seller must collect it. The United States does not use a national VAT or GST invoice regime. State and local sales and use tax rules control the taxability, rate, and sourcing of a transaction. Washington, for example, has a 6.5% state portion plus a local portion that varies by city or county.
Invoice mistakes in the United States often come from treating the country like a VAT jurisdiction. There is no national VAT or GST registration number to place on an invoice. A seller making taxable sales may need state-level sales-tax registration, such as a California seller's permit for retailers engaged in business in California selling taxable tangible personal property.
Service taxability also varies by state and service type. California generally taxes retail sales of tangible personal property and only some service or labor charges, while Texas defines 16 broad categories of taxable services. Remote sellers also need to watch nexus rules. South Dakota's rule at issue in Wayfair applied above $100,000 of goods or services delivered into the state or 200 separate transactions annually.
A one-off invoice is enough for a single project, a fixed-fee job, or a customer that only needs a clean PDF or payment record. It works when the amounts are already final, the tax decision is clear, and no one needs to reconcile time entries, expenses, approvals, and prior invoices later.
A managed workflow is better when billable time, expenses, client rates, non-billable work, and invoice status all need to stay connected. Everhour Billing & Invoicing converts tracked billable time and expenses into invoices, calculates amounts from rates while excluding non-billable tasks, and exports invoices to QuickBooks Online, Xero, or FreshBooks with status sync back to Everhour.

No. For ordinary private-sector business, the United States has no prescribed federal private-sector invoice form. Businesses may choose a recordkeeping system suited to the business if it clearly shows income and expenses. Invoices still matter because IRS Publication 583 lists them as supporting documents for business transactions and gross receipts.
An invoice for a United States transaction should not show VAT or GST as a national tax. The country uses state and local sales and use tax instead. The seller decides whether sales tax applies based on state and local rules, nexus, product or service taxability, and where the customer receives the goods or services.
A private-sector invoice in the United States usually does not need a VAT or GST number because that registration system does not exist nationally. A seller may include state sales-tax permit details when relevant. A Taxpayer Identification Number or EIN is usually exchanged through Form W-9 or required agency procedures, not printed on every ordinary invoice.
Federal procurement invoices follow FAR proper-invoice rules. FAR 32.905 lists fields such as contractor name and address, invoice date and number, contract or order references, descriptions, quantities, unit and extended prices, shipping and payment terms, remittance details, defect-contact details, and TIN or EFT banking data when agency procedures require them.
Private businesses set payment terms by contract, policy, or customer agreement, such as due on receipt, net 15, or net 30. Federal contract invoices use a clearer national baseline: FAR 32.904 generally sets payment due 30 days after the billing office receives a proper invoice or 30 days after government acceptance, whichever is later.
Everhour Billing & Invoicing lets users select uninvoiced billable time and expenses, preview the breakdown, and generate an invoice from rates, time, and billable expenses while excluding non-billable work. Invoices can be exported to QuickBooks Online, Xero, or FreshBooks, with status, number, issue date, and amount visible back in Everhour.
Create invoices from approved time, rates, expenses, and client terms. Everhour keeps billed work from being reused and connects invoice status to billing reports.
