Tracked hours flow straight into a polished invoice — no copy-paste, no manual math.
A Net 30 invoice tells the buyer that payment is due 30 days after the invoice date, unless your contract defines the clock differently. The document still needs the ordinary invoice parts: seller and buyer details, invoice number, issue date, due date, line items, subtotal, tax line when applicable, total amount due, payment terms, and remit-to instructions.
The United States has no prescribed federal private-sector invoice form and no national VAT or GST invoice regime. For ordinary businesses, invoice content is mainly a recordkeeping and contract matter. IRS Publication 583 treats invoices as supporting documents that help show amounts and sources of gross receipts, so the invoice should be clear enough to match income, client records, and payment history.
The term should name both the rule and the date. Write "Net 30" and include a due date, such as "Due April 30, 2026" on an invoice issued March 31, 2026. A buyer should not need to count days, guess whether weekends matter, or search the contract to know the expected payment date.
Contract language controls special cases. Some clients define Net 30 from receipt of a proper invoice, approval of work, or acceptance of goods or services. Federal contract invoices are a national exception with specific rules: FAR 32.904 generally sets payment due as the later of 30 days after the billing office receives a proper invoice or 30 days after government acceptance, with shorter timelines for some food and construction payments.
A useful template keeps the approval path short. Add your business name and address, the customer's billing name and address, a sequential invoice number, issue date, due date, line-item descriptions, quantities, rates, extended prices, subtotal, tax line, discounts or credits, total due, payment instructions, and a contact for questions.
Line items should describe the purchase at the level the buyer approved. For services, a line can read "Website support, March 2026, 12 hours × $95 = $1,140." For products, include quantity, unit price, and delivery detail when relevant. Keep invoices distinct from receipts, estimates, and quotes. An invoice requests payment, a receipt proves payment received, and an estimate or quote presents pre-work pricing.
A single template is enough for one client, one invoice, and a clear payment term. It works well when you already know the line items, tax treatment, due date, and payment method. Save the finished invoice with the source records that support the charge, including approved scope, delivered work, expenses, and payment correspondence.
A managed workflow becomes necessary when billable time, project costs, approvals, and follow-up live in different places. Everhour reporting gives teams configurable views with columns, grouping, filters, date ranges, and exports, so invoicing records can connect back to billable time, costs, invoice status, and project profitability instead of living as isolated files.

Net 30 usually means payment is due 30 days after the invoice date, but the contract can define a different starting point. Some agreements start the period when the buyer receives a proper invoice, approves the work, or accepts goods or services. Put the exact due date on the invoice to remove ambiguity.
The issue date matters when the agreement says payment is due 30 days from invoice date. The receipt date matters when the contract says the clock starts after the buyer receives a proper invoice. Federal contract payment timing under FAR 32.904 generally uses the later of proper invoice receipt or government acceptance for most payments.
Include sales tax only when state and local rules require it for the sale. The United States has no national VAT or GST invoice regime and no single national sales tax rate. Sales tax depends on nexus, the buyer's location, the product or service, and state and local taxability rules.
A United States invoice does not need a VAT number because the United States does not use a national VAT or GST invoice regime. Sellers that make taxable sales may need state-level sales-tax registration, such as a seller's permit or sales-tax account, depending on the state and the sale.
Missing approval details delay payment. Buyers often need a purchase order, contract reference, correct billing entity, clear line-item description, tax treatment, payment instructions, and a reachable contact. A Net 30 label does not fix an invoice that the buyer cannot match to an approved order or delivered work.
Everhour Reporting lets teams build reports with 45+ columns, grouping, filters, date ranges, and exports. A team can review billable time, non-billable time, costs, invoice status, and project details before sending a Net 30 invoice or following up on unpaid work.
Everhour Billing & Invoicing converts tracked billable time and expenses into client invoices, using project or member rates while excluding non-billable work. Invoice data can be grouped by project, task, person, date, or another available breakdown before export to QuickBooks Online, Xero, or FreshBooks.
Use a template for one invoice, then keep recurring Net 30 billing tied to reports, exports, and invoice status. Everhour connects billing records to project work and profitability.
