Use this page to prepare a short, specific reminder for an unpaid invoice. The practical goal is simple: identify the invoice, state the amount due, restate the due date or overdue status, and give the buyer a direct payment path. A reminder works best when it removes friction instead of sounding like a new negotiation.
For ordinary United States businesses, invoice content is mainly a recordkeeping and contract matter rather than a single federal invoice-format requirement. Invoices still matter because they support business transactions and gross receipts records. A payment reminder should therefore point back to the original invoice number, issue date, due date, customer name, total due, payment terms, and remit-to details.
A strong reminder starts with the invoice facts, then adds the action requested. Include the original invoice number, the amount due, the services or goods billed, the due date, and the accepted payment methods under your policy or contract. United States coins and currency are legal tender, but no federal statute requires private businesses to accept cash for goods or services unless state law says otherwise.
Keep sales tax language tied to the invoice, not the reminder. The United States does not use a national VAT or GST invoice regime. State and local sales and use tax rules control whether tax applies, with rates based on the applicable state and local jurisdiction. Service taxability also varies by state and service type, so do not add a flat national tax line during follow-up.
The first reminder can stay neutral: the invoice is due, payment has not posted, and the customer can use the listed payment method. After the due date passes, the message should name the number of days overdue and reference any late fee, interest, or service pause only if the contract or policy allows it. Specificity beats pressure.
Federal contract invoices need a different level of precision. FAR rules define a proper invoice with contractor details, invoice date and number, contract or order references, line items, terms, payee details, contacts, and TIN or EFT banking data when agency procedures require them. For most federal contract invoice payments, the due date is generally 30 days after receipt of a proper invoice or 30 days after government acceptance, whichever is later.
A one-off reminder is enough when the invoice is isolated, the amount is easy to verify, and the customer only needs a nudge. It is also enough for a small batch of invoices if your records clearly show which invoices are unpaid, partially paid, or already closed. The reminder should match the invoice, not rebuild the invoice from memory.
A managed workflow becomes necessary when tracked billable time, project rates, discounts, taxes, and expenses feed the invoice. Everhour supports project, member, and custom task rates, with dated rate changes that preserve older calculations. That rate history helps keep the reminder amount aligned with the invoice that was actually issued.

Send a reminder shortly before the due date for high-value invoices and shortly after the due date for overdue invoices. The message should include the invoice number, amount due, due date, payment terms, and payment method. For federal contract work, check the proper-invoice and acceptance timeline because FAR rules generally use a 30-day payment timing standard for most payments.
A payment reminder should include the customer name, invoice number, issue date, due date, total due, short description of goods or services, payment method, and remit-to details. Add the original invoice as an attachment or link when possible. Do not change the sales tax treatment in the reminder unless the original invoice was corrected.
A reminder should include late fees only when your contract, accepted terms, or applicable policy supports them. State the fee separately from the original invoice balance so the customer can see the difference between the unpaid invoice amount and any added charge. If no late fee applies, ask for payment of the invoice balance only.
A payment reminder is a request to pay an unpaid or overdue invoice. A receipt confirms payment received. An invoice requests payment for goods or services, while a quote or estimate is a pre-work price document. Keep those documents separate so your records show the correct stage of the transaction.
United States invoices do not use a national VAT or GST registration number. Sellers that make taxable sales may need state-level sales-tax registration, such as a seller's permit where required. A payment reminder should repeat the invoice's tax details instead of adding a VAT-style field that does not apply to ordinary United States invoices.
Everhour separates internal cost rates from client-facing billable rates and supports default per-person rates with per-project overrides. Dated rate changes preserve older calculations, so teams can confirm that an unpaid invoice reflects the project, member, or task rate that applied when the work was billed.
Everhour turns tracked billable time and expenses into invoices, marks invoiced time so it is not reused, and keeps invoice status visible after export to QuickBooks Online, Xero, or FreshBooks. That status gives teams a cleaner view of billed, uninvoiced, and outstanding work.
Track approved billable time, apply the correct rates, and keep invoice follow-up tied to project records. Everhour gives teams rate-aware billing visibility before reminders go out.
