A United States invoice should give the buyer enough detail to approve payment and give the seller enough support for revenue records. The IRS treats invoices as supporting documents for business transactions and gross receipts. For ordinary private-sector work, there is no prescribed federal private-sector invoice form, so the format comes from the contract, customer requirements, accounting process, and state tax rules.
Start with the practical basics: seller name, buyer name, invoice number, invoice date, payment due date, line items, quantities, rates, discounts, tax, total due, and payment instructions. Add a purchase order number, project name, service period, or delivery address when the buyer uses those fields to route approvals. A clean invoice reduces back-and-forth before payment starts.
A service invoice usually needs a line for each billable activity, such as "Design review, March 1-7, 6 hours at $90." A product invoice needs item names, quantities, unit prices, and delivery details. Both formats need a clear subtotal, any discount, any applicable sales tax, and the final amount due in USD unless the contract allows another currency.
Federal contract invoices have stricter national rules than ordinary commercial invoices. FAR 32.905 defines a proper invoice with 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. FAR 32.904 generally uses a 30-day payment timing standard for most federal contract invoice payments.
The United States does not use a national VAT or GST invoice regime. State and local sales and use tax rules control whether tax belongs on the invoice, which rate applies, and which seller registration applies. Washington, for example, has a 6.5% state sales tax portion plus a local portion that varies by city or county and is collected based on where the customer receives the goods or services.
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 check nexus rules. South Dakota's law, reviewed in South Dakota v. Wayfair, applied to sellers delivering more than $100,000 of goods or services into the state or making 200 or more separate transactions annually.
A one-off invoice tool is enough when you need a simple document for a single sale, a small project, or a customer that only wants a PDF with clear payment terms. It works best when sales tax treatment is already known, the line items are final, and no one needs to approve timesheets before billing.
A managed workflow matters when billable time feeds invoices every week or month. Everhour supports project billing status, task-level non-billable controls, custom task rates, member-rate exceptions, and admin reports for billable time, non-billable time, billable amount, and cost. That structure keeps invoice totals tied to approved work instead of rebuilt from scattered notes.

No single federal private-sector invoice form applies to ordinary United States businesses. The invoice still needs enough detail to support payment, accounting, and tax records. Seller and buyer details, invoice number, date, line items, payment terms, tax treatment, and total due are standard because they make the transaction auditable and easier for the buyer to approve.
A United States invoice does not use a national VAT or GST regime. State and local sales and use tax rules apply where required. The seller must check the state, local jurisdiction, product or service taxability, customer location, and nexus rules before adding sales tax to the invoice.
A United States invoice usually does not show a VAT or GST registration number because the country has no national VAT or GST invoice system. Businesses use a state seller permit or sales-tax account where required for taxable sales. A TIN or EIN is commonly handled through Form W-9 or federal agency procedures, rather than printed on every private invoice.
Service taxability depends on the state and the type of service. California generally taxes retail sales of tangible personal property and only some service or labor charges. Texas defines 16 broad categories of taxable services. Treat each state as its own rule set before adding or omitting tax.
There is no general private-sector United States e-invoicing mandate. Federal procurement is different: OMB directed federal agencies to transition appropriate federal procurements to electronic invoicing by the end of FY 2018, and Treasury's Invoice Processing Platform serves federal agencies and vendors. Private businesses follow customer, contract, accounting, and state requirements.
Everhour lets admins set project billing status, mark specific tasks as non-billable, apply custom task rates, and set member-rate exceptions. Reports can show billable time, non-billable time, billable amount, and cost, so invoice totals reflect the work that should actually be billed.
Everhour Billing & Invoicing converts uninvoiced billable time and expenses into client invoices. Invoice data can be grouped by project, task, person, date, or other breakdowns, then exported to QuickBooks Online, Xero, or FreshBooks as drafts for accounting review.
Track billable and non-billable work before invoice day. Everhour gives teams project billing controls, task-level exclusions, custom rates, and billing reports that support cleaner client invoices.
