Invoices and receipts for SaaS companies

SaaS companies bill recurring subscriptions, per-seat plans, one-off setup or onboarding and occasional overage charges. Each cycle and each one-off needs clean paperwork. Receipt Caker lets you build subscription invoices, setup invoices and payment receipts in your browser, with totals calculated automatically, then export a free PNG or a watermark-free PDF with your logo.

How do SaaS companies invoice customers?: Receipt Caker is a free browser tool SaaS companies use to bill customers. Add line items for the subscription, seats, setup or overage, each with quantity and unit price, and the subtotal, tax and total calculate automatically. Include the billing period, plan name and payment reference, preview it live, then export a free PNG or a watermark-free PDF with your logo to send to the customer.

Billing the subscription cycle

A SaaS subscription is billed per period, whether monthly or annual, often with a per-seat component. Each invoice should state the plan, the period it covers and the seat count so the customer can reconcile it against their account.

Receipt Caker lets you list the plan as a line item and seats as another, with the period clearly noted on the document, and the totals build automatically. Note that Receipt Caker produces the invoice for you to send; it does not run recurring billing or charge cards, so you create each period invoice and send it yourself.

One-off setup and onboarding

Many SaaS deals start with implementation work, data migration or onboarding that is billed once, separately from the subscription. Keeping these off the recurring invoice avoids confusion in the customer accounts team.

You can build a dedicated setup or onboarding invoice listing the one-off services, and the customer sees clearly that this is a start-of-contract charge rather than an ongoing cost. It keeps the recurring subscription invoice clean and predictable.

Overage and receipts

When usage exceeds a plan allowance, whether extra seats, storage or API volume, that overage needs billing. Itemizing it as its own line makes clear it is on top of the standard plan.

Add overage lines to the period invoice or issue a separate overage invoice, whichever suits your billing. When any invoice is paid, you can issue a payment receipt from Receipt Caker so the customer has a clean record for their books, closing out the transaction tidily.

Frequently asked questions

Does Receipt Caker handle recurring subscription billing?

No, and it is important to be clear about that. Receipt Caker is a document generator: it builds a professional, itemized invoice or receipt in your browser and lets you export it as a PNG or a watermark-free PDF. It does not run recurring billing, store card details, charge customers automatically or send anything on a schedule. For each billing period you create the subscription invoice yourself, listing the plan and seats with the period covered, and the subtotal, tax and total calculate automatically. Then you export it and send it to the customer through your own channels. Many small SaaS teams are happy to generate period invoices manually because it keeps the paperwork under their control and every document is private, rendered entirely on their own device. If you later automate billing, the tool still works well for one-off invoices and receipts.

How do I bill a one-off setup fee?

Setup, implementation and onboarding are usually one-off charges billed at the start of a contract, separate from the recurring subscription. In Receipt Caker you build a dedicated setup invoice listing each service, such as implementation, data migration or training, as its own line item with a description and price, and the totals calculate automatically. Keeping this off the subscription invoice makes it clear to the customer accounts team that the charge is a one-time start-of-contract cost rather than an ongoing fee, which avoids confusion when they reconcile future invoices. The tool does not link the setup invoice to your subscription billing, so you create it as a standalone document and send it yourself. Presenting setup work on its own clean, itemized invoice keeps your recurring subscription invoices predictable and makes the full cost structure of the deal transparent to the customer.

How do I show overage charges?

When a customer exceeds a plan allowance, such as extra seats, additional storage or API calls beyond the included volume, you bill the overage as its own line item. In Receipt Caker you can add overage lines directly to the period invoice, clearly labelled and priced so the customer sees the standard plan and the extra usage separately, or you can issue a dedicated overage invoice. Each line has a description, quantity and unit price, and the subtotal, tax and total recalculate automatically. Itemizing overage rather than folding it into the plan price keeps the invoice transparent and makes it easy for the customer to understand why a period cost more. The tool does not track usage or calculate overage for you, so you enter the figures from your own metering. This keeps you in full control of how additional usage is presented on each invoice.
