Use this page to prepare invoices for SaaS customers who pay for product access, services, add-ons, or usage. A SaaS invoice usually covers a billing period, such as one month or one year, and identifies the plan, customer, currency, subtotal, tax, total due, amount paid, amount remaining, and payment status.
The invoice should also separate recurring subscription charges from non-recurring items. A setup fee, implementation charge, off-cycle adjustment, or manual credit belongs on its own line so the customer can approve it without guessing whether it changed the base subscription price.
A practical SaaS invoice starts with seller and customer identity fields, invoice date and number, billing-period dates, line items, payment terms, and remittance instructions. Customer tax IDs belong on the invoice when the billing workflow requires them, but the United States does not use a national VAT or GST invoice regime.
Line items should name the product or service, quantity, unit price, period covered, discounts, tax, and total. For a customer on a $499 monthly plan with 3 admin seats and a $250 setup fee, separate lines make the recurring charge, seat charge, and one-time charge reviewable.
Usage-based SaaS billing depends on recorded usage events during the billing period. The invoice should show the metric the customer agreed to buy, such as seats, API calls, storage, or transactions, plus the dates covered by the usage count. Missing period dates create disputes because the customer cannot reconcile the charge to system activity.
United States sales and use tax is state and local, not federal VAT or GST. Taxability depends on the product or service, customer location, seller registration, nexus, and local rules. Service taxability varies by state and service type, so the tax line should reflect the actual billing setup rather than a generic national rate.
A one-off invoice works when you need a single bill for a small customer, a setup fee, or a manual subscription adjustment. It is enough when the charge is simple, the approval path is short, and you can keep the supporting record with the customer account.
A managed workflow matters when customer work, implementation, support, or custom development feeds the invoice. Everhour can separate billable and non-billable time by project, task, custom task rate, or member-rate exception, then report billable time, non-billable time, billable amount, and cost for cleaner SaaS billing review.

A SaaS invoice should include seller and customer details, invoice number, invoice date, billing-period dates, currency, line items, subtotal, tax totals, total due, amount paid, amount remaining, payment status, and payment instructions. Recurring subscription charges, usage charges, setup fees, credits, and discounts should appear as separate lines when they affect the customer's approval.
Yes. SaaS invoices should show the billing period because the customer is paying for access or usage over a defined time. Monthly and annual subscriptions need period dates, and usage-based lines need the dates covered by the recorded usage events. Clear period dates reduce disputes over upgrades, renewals, prorations, and off-cycle adjustments.
No United States VAT or GST registration number exists for invoices. The United States uses state and local sales and use tax instead of a national VAT or GST invoice regime. A SaaS seller that makes taxable sales may need state-level sales-tax registration, and the tax line depends on state and local rules.
Yes. A SaaS invoice can include a recurring subscription line and separate one-time invoice items, such as setup fees, implementation charges, off-cycle fees, or credits. Separate lines make the invoice easier to approve because the customer can see which charges repeat and which charges apply only once.
Missing detail causes payment delays. A customer reviewing a SaaS invoice needs the plan name, billing period, quantity, usage metric, tax line, total due, payment status, and due date. A vague line such as "software services" forces the buyer to ask for backup before approving payment.
Everhour lets admins set project billing status, mark specific tasks non-billable, use custom task rates, and set member-rate exceptions. Reports can show billable time, non-billable time, billable amount, and cost, so implementation or customer success work can be reviewed before it reaches an invoice.
Track approved customer work by project and task, separate billable from non-billable time, and use Everhour reports to keep SaaS invoicing tied to real delivery.
