# Invoices & Receipts

> Where to find your payment documents, what gets a receipt vs. an invoice, and how pay-as-you-go usage is invoiced.

Every payment on JoJ API produces a document. You can view and download all of them as PDFs from [Workspace → Billing](https://jojapi.com/workspace/billing) — each payment row has an **Invoice** or **Receipt** button.

## Receipts — wallet top-ups

Adding funds to your wallet is a **prepayment** into your balance, not a purchase — so a top-up produces a **receipt** (numbered `RCP-…`), deliberately not a tax invoice. The receipt is also attached to your top-up confirmation email.

The tax invoice is issued later, when you actually spend the balance.

## Invoices — subscription payments

Every subscription payment — the initial purchase and each renewal, whether charged to your card or paid from your wallet balance — produces an **invoice** with the API, the plan and the billing recurrence on it. Invoices are numbered sequentially per account.

A few older card payments were invoiced by our payment provider; those rows open the hosted invoice instead.

## Invoices — pay-as-you-go usage

Pay-as-you-go usage is paid from your wallet balance in real time, as you call the API. For your records, that spend is invoiced **per billing period**: shortly after each pay-as-you-go period ends, an invoice is issued covering exactly that period.

On the invoice you'll find:

* the **service period** the invoice covers,
* one line per **billable object** you consumed (Credits, AI tokens, …),
* a split **per pricing tier** when your usage crossed tier boundaries — each line shows the units, the exact unit price of that tier, and the amount, so every line verifies as units × unit price.

The amount was already deducted from your balance during the period, so the invoice arrives marked **Paid** — it never triggers a new charge. Periods with no billable usage produce no invoice.

## Your billing details

Set the details printed on your documents in **Billing → Billing details**: personal or company name, address, phone, and tax IDs — you can add several, across countries (VAT, GST, EIN, …). If you paid by card before, we prefill what your payment provider shared; you can edit everything.

Issued documents are **frozen**: editing your billing details later changes future documents only, never a past invoice.
