Use this page to prepare an invoice for a United States customer, contractor relationship, or project billing workflow. Ordinary private-sector invoices in the United States are mainly recordkeeping and contract documents. IRS Publication 583 lists invoices as supporting documents that show business transactions and the amounts and sources of gross receipts, but the IRS does not prescribe one national private-sector invoice form.
A practical invoice still needs a clear seller name, buyer name, invoice number, invoice date, payment due date, line-item description, quantity or hours, unit price, taxes or adjustments when applicable, total due, and payment instructions. Add the purchase order, contract reference, project name, and service period when the buyer uses approvals or accounts payable matching.
The United States does not use a national VAT or GST invoice regime. State and local sales and use tax rules decide whether you must collect tax, which rate applies, and which sales-tax registration you need. Washington, for example, has a 6.5% state 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. Treat sales tax as a jurisdiction decision, not a default invoice line. Keep documentation for nexus, exemption certificates, delivery location, and product or service classification.
Most business invoices follow the contract, purchase order, or customer billing instructions. Federal procurement has a stricter national rule. FAR 32.905 defines a proper federal contract invoice to include 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 data when agency procedures require them.
Federal payment timing also has a specific baseline. FAR 32.904 generally sets the due date for most federal contract invoice payments as the later of 30 days after the billing office receives a proper invoice or 30 days after government acceptance of the goods or services. Private customers follow the payment term in the agreement, such as due on receipt, net 15, or net 30.
A one-off invoice works when you bill a single project, a fixed fee, or a short engagement with simple lines. It is enough when you can verify the work, tax treatment, payment term, and customer details without pulling data from several systems. It becomes fragile when billing depends on approved hours, mixed rates, non-billable work, expenses, or repeated client billing.
Everhour fits the managed workflow side of that line. Admins can set project billing status, mark specific tasks as non-billable, apply custom task rates, set member-rate exceptions, and report on billable time, non-billable time, billable amount, and cost. That structure keeps invoice totals tied to the work records behind them.

The United States has no prescribed federal private-sector invoice form. Businesses choose a recordkeeping system suited to the business if it clearly shows income and expenses. Invoices still matter because they support gross receipts, customer billing, sales-tax decisions, and contract payment records.
A United States invoice should not use VAT or GST unless the transaction involves a foreign tax regime that actually applies. The United States uses state and local sales and use tax. Sellers that make taxable sales may need state-level sales-tax registration, such as a seller's permit in California for taxable retail sales.
Applying one generic sales-tax rate across all United States customers creates disputes. Rates and taxability depend on state and local rules, delivery location, product or service type, nexus, and exemptions. A customer in one city can face a different total rate than a customer in another city in the same state.
Private invoices do not universally need an EIN. Businesses often provide a Taxpayer Identification Number through Form W-9 when a payer must file IRS information returns. Federal contract invoices include a TIN only when agency procedures require it, so the contract or customer onboarding process controls the request.
There is no general private-sector federal e-invoicing mandate for ordinary United States businesses. Federal agencies were directed 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 rather than all private businesses.
Everhour lets admins set each project's billing status, mark individual 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 review starts from categorized work records.
Everhour can turn uninvoiced time and expenses into invoices, then export invoices to QuickBooks Online, Xero, or FreshBooks as drafts. Invoice status, number, issue date, and amount sync back to Everhour, keeping billing reports connected to accounting follow-up.
Use Everhour to classify billable work before invoice review. Project billing status, non-billable task controls, custom rates, and admin reports keep client billing tied to verified time.
