Tracked hours flow straight into a polished invoice — no copy-paste, no manual math.
Use this page to prepare an invoice that documents a sale, service, or project charge in a clear format. The finished invoice should identify the seller and buyer, assign an invoice number, show issue and due dates, list each charge, apply the correct tax treatment, and state payment terms. It is a request for payment, separate from a receipt that proves payment received.
For ordinary United States private-sector businesses, no single federal statute prescribes one invoice format. Invoices still matter because they support bookkeeping, income records, client payment workflows, and contract files. IRS Publication 583 lists invoices among supporting documents that record business transactions and show the amounts and sources of gross receipts.
A complete invoice starts with seller name, buyer name, invoice date, due date, unique invoice number, remit-to details, and payment instructions. Line items should describe the work or goods, quantity, rate, discount if used, subtotal, tax line, total amount due, and payment terms. A service invoice can show hours and rates, while a product invoice can show units and unit prices.
United States invoices do not use a national VAT or GST registration number because the country does not use a national VAT or GST invoice regime. Sales and use tax is imposed and administered by states and local jurisdictions. Taxability depends on nexus, the product or service sold, and the place of sale, not a single national rate.
Security starts with data minimization. Put the details required to bill, collect, and reconcile the invoice on the document, then keep unnecessary identifiers out of the client-facing version. A state seller permit or sales-tax account may belong on records where required, but a Taxpayer Identification Number or EIN usually belongs in Form W-9 or agency procedures, not on every routine invoice.
Delivery and storage matter after the invoice is created. Send invoices through the agreed business channel, avoid editable files when a locked PDF is enough, and keep a copy with the contract, purchase order, payment confirmation, and any tax support. For federal procurement, FAR rules define proper invoice fields, and TIN or EFT banking data appears only when agency procedures require it.
A free invoice is enough for a single sale, a small project, or a client that only needs a PDF for payment approval. It works best when you already know the billable work, tax treatment, payment terms, and remit-to details. One-off documents become harder to manage when several people track time, projects use different rates, or clients ask for supporting detail.
A managed workflow becomes the better system once tracked time and expenses need to flow into invoices without re-keying. Everhour Billing & Invoicing calculates invoice amounts from billable time, project or member rates, and billable expenses while excluding non-billable work. It also supports client defaults, invoice customization, and exports to QuickBooks Online, Xero, or FreshBooks.

A secure invoice includes the data needed for payment and recordkeeping, then avoids unnecessary sensitive details. Seller and buyer names, invoice number, dates, line items, totals, payment terms, and remit-to details belong on the invoice. Internal IDs, personal tax identifiers, bank details beyond the agreed payment method, and editable source files should stay out unless the client or contract requires them.
Ordinary United States private-sector invoices do not have one prescribed federal format. Businesses may choose a recordkeeping system suited to the business if it clearly shows income and expenses. Federal contracts are the clearest national exception, since FAR 32.905 defines proper invoice fields for federal procurement.
Sales tax belongs on an invoice only when the seller has an applicable state or local collection obligation and the sale is taxable. The United States has no single national sales-tax rate. Rates and rules depend on state and local law, nexus, product or service taxability, and where the customer receives the goods or services.
A PDF is a practical invoice format because it preserves the layout and reduces accidental editing. The sender still needs to use a delivery channel accepted by the client and keep the invoice with supporting records. Federal electronic invoicing systems apply to federal-agency and vendor workflows, not to a general private-sector e-invoicing mandate.
An invoice requests payment for goods or services provided or due under agreed terms. A receipt proves payment received. A quote or estimate gives a pre-work price offer before the seller issues an invoice. Mixing these documents creates reconciliation problems because each one supports a different step in the billing cycle.
Everhour Billing & Invoicing converts tracked billable time and expenses into invoices, calculates amounts from rates, and excludes non-billable work. Client records can store projects, contacts, taxes, discounts, and payment terms so repeat invoices start with the right defaults.
Everhour exports invoices to QuickBooks Online, Xero, or FreshBooks as drafts managed in the accounting tool. Invoice status, number, issue date, and amount sync back to Everhour so billing records stay connected to project and time data.
Use a secure one-off invoice for simple billing. For repeat client work, Everhour connects approved billable time, rates, expenses, and accounting exports into one invoicing workflow.
