# Keep sales invoices

Use this guide to keep the invoices you send to your clients next to your receipts. Mail to a second routed address is filed as a sales invoice instead of a receipt, read for the client and VAT details, and shown on **Receipts** under **Invoices**. Money coming in on an imported bank statement is then matched to it.

## Prerequisites

- Email set up and working; see [Set up email](/docs/how-to/set-up-email/). The same allowed senders (**Settings** > **Email** > **Email senders**) and SPF check apply to invoice mail.
- A second address on the same domain, for example `invoices@receipts.example.com`. It must differ from the receipt address and from **Forward a copy to**.
- Invoices as PDF or image attachments. An email without an attachment is not read as an invoice.

## Steps

1. **Route the invoice address to the Worker**

   In the Cloudflare dashboard, go to **Compute > Email Service > Email Routing > Routing Rules** and select **Create routing rule**. Enter the local part of the invoice address, choose **Send to a Worker** as the **Action**, pick your Nuits Receipts Worker as the **Destination**, and select **Save**.
2. **Set the invoice address in the app**

   Open **Settings > Email** and fill in **Invoice address**. Tick "I’ve added the Email Routing rule for this address", which shows once you change the address, and press **Save**.

   At deploy time the same value is the `INVOICES_ADDRESS` variable.
3. **Set your business names**

   Open **Settings > Business**, fill in **Your business names** as they appear on the invoices you send, comma separated (up to 20), and press **Save**.

   An invoice that names someone else as the seller is flagged **Did you send this invoice?** and offers **Move to receipts**. Leave the field empty to skip the check. At deploy time this is the `SELLER_NAMES` variable.
4. **Optional: set your payment terms**

   In **Settings > Business**, **Payment terms, days** (default 30) decides when an invoice without a printed due date counts as overdue.
5. **Copy the invoice address when you send an invoice**

   Add the invoice address as CC or BCC when you email an invoice to a client, from an address allowed in **Settings** > **Email** > **Email senders**.

You can also add invoices by hand: press **Add** and choose **Invoices you sent** under "What are these?". Pressed on the **Invoices** page, **Add** opens with it already chosen. Several files can be added at a time.

## Check it worked

1. **Receipts** shows **To do**, **All** and **Invoices** at the top, each with its count. Select **Invoices**.
2. The test invoice is listed there for its month with its client, amount, number and one status, such as "Due 18 Sep" or **Check**.
3. If it is flagged, open it and fix what it asks about. An email with no attachment is held with the flag **Where is the invoice?**
4. After you import a bank statement with the payment, the invoice shows **Paid** with the date. A payment is matched automatically when the amount fits and the bank reference carries the invoice's reference or number, or the payer is the client. Otherwise it is suggested on **Bank**.

An invoice paid somewhere else (for example a payment platform payout) can be marked paid by hand: open it, open **Paid another way?**, fill in **Paid on** and **How**, and press **Mark paid**. Every row on **Invoices** has a tick box. To mark several, tick them, select **Mark paid** in the bar and fill in **Paid on** and **How** once. The same bar has **Discard** and **Read again**.

## Change the invoice address later

Add a routing rule for the new address first, then change **Invoice address** in the app. Mail to the old address is still filed as an invoice for 30 days, so messages already on their way are not filed as receipts. Remove the old routing rule when you are done.
