Tracked hours flow straight into a polished invoice — no copy-paste, no manual math.
Use this page to produce a clean invoice for billable work, products, expenses, or project fees. The finished document should identify the seller and buyer, show a unique invoice number, list issue and due dates, describe each line item, state quantities and rates, show tax separately when applicable, and give the client a clear remit-to address or payment instruction.
Reliability comes from consistency. Use the same numbering pattern, the same business name, the same payment terms, and the same line-item structure across invoices. An invoice is a payment request. A receipt proves payment received, while an estimate or quote gives a pre-work price offer. Keeping those documents separate prevents client confusion and bookkeeping cleanup.
A standard United States private-sector invoice does not follow one federally prescribed invoice form. Businesses may use any recordkeeping system suited to the business if it clearly shows income and expenses, and invoices serve as supporting documents for business transactions. That flexibility still leaves practical requirements: client identity, invoice date, invoice number, goods or services sold, amount due, and payment terms.
Line items should explain the charge without making the client reconstruct the work. A useful service line reads like: "Website implementation, 12 hours × $95, $1,140." Product invoices need quantity, unit price, and extended price. Add discounts, deposits, shipping, or reimbursable expenses as separate lines so the subtotal, tax line, and total remain easy to audit.
The United States does not use a national VAT or GST invoice regime, and there is no United States VAT/GST registration number to place on ordinary invoices. State and local sales and use tax rules control whether you collect tax. Rates depend on the applicable state and local rate, and service taxability varies by state and service type.
A reliable invoice does not add a flat sales-tax percentage by habit. The tax decision starts with nexus, the buyer's location, and whether the product or service is taxable in that jurisdiction. For example, Washington combines a 6.5% state portion with a local portion, while Texas lists broad categories of taxable services. Payment method also follows policy or contract, since federal law does not require private businesses to accept cash unless state law says so.
A one-off invoice works when you need a single PDF for a simple sale, a fixed project fee, or a small client request. It is enough when the amounts are already known, tax treatment is clear, and no future report needs to tie time, cost, rate, and invoice status together.
A managed workflow fits better when billable time, expenses, and rate rules drive the invoice. Everhour separates internal cost rates from client-facing billable rates, supports default per-person rates and per-project overrides, preserves dated rate changes, and prices billable work by project, member, or task. That structure reduces re-keying and keeps invoice amounts tied to the work record.

A reliable invoice has a unique invoice number, issue date, due date, seller and buyer details, line-item descriptions, quantities, rates, subtotal, tax line when applicable, total amount due, payment terms, and remit-to instructions. The numbering pattern should stay consistent so you can match invoices to payments, deposits, and accounting records without manual reconstruction.
No prescribed federal private-sector invoice form applies to ordinary United States businesses. IRS guidance treats invoices as supporting documents that help show gross receipts and business transactions. Federal contracts are different. FAR rules define proper invoice fields for federal procurement, including contractor details, invoice number, contract reference, line items, payment terms, and required TIN or EFT data when agency procedures require them.
Sales tax belongs on the invoice only when the seller has the applicable collection obligation and the sale is taxable under the relevant state and local rules. The United States has no single national sales-tax rate and no VAT or GST invoice regime. Service taxability also varies by state and service type, so the tax line must match the buyer location and sale category.
A reused or inconsistent invoice number creates the most avoidable recordkeeping trouble. Duplicate numbers make payment matching harder, especially when a client pays late, partially pays, or asks for a revised copy. Use a sequential pattern, keep voided invoices in the record, and issue a corrected invoice or credit note according to your accounting process instead of silently overwriting the original.
A PDF is acceptable for ordinary private-sector invoicing when the client accepts it and your records clearly show income and expenses. Federal procurement has its own procedures, and agencies moved appropriate procurements toward electronic invoicing by the end of fiscal year 2018. Private businesses should follow the contract, client portal, or accounting process agreed with the buyer.
Everhour separates internal cost rates from client-facing billable rates, with default per-person rates and per-project overrides. Rate changes can apply from a chosen date, so older reports keep their original calculations while current invoices use the correct project, member, or task rate.
Everhour Billing & Invoicing lets users select uninvoiced billable time and expenses, preview the breakdown, and generate an invoice without rebuilding timesheets manually. Invoiced time is marked as invoiced, which prevents the same work from appearing again in a later invoice.
Track rates, time, and billable expenses before the invoice is due. Everhour connects project work to client billing so invoice amounts stay tied to approved records.
