# Manage Invoices, Credit Notes, and Finance in Avstarna

> Create and send invoices, issue credit notes, track financial mutations, and sync with e-Boekhouden accounting software — all from within Avstarna.

Avstarna's Finance & Invoicing module handles the full financial lifecycle of your orders — from generating a professional invoice to syncing transactions with your accounting software. Everything lives inside Avstarna, so your production data and financial records stay connected without manual exports or double-entry.

## Creating an Invoice

You create invoices directly from an order in Avstarna. Once an order is ready to bill:

<Steps>
  <Step title="Open the order">
    Navigate to the order you want to invoice in your order management section.
  </Step>

  <Step title="Create the invoice">
    Select **Create Invoice** from the order actions. Avstarna generates an invoice pre-filled with the order lines, customer details, and your configured payment terms.
  </Step>

  <Step title="Review and send">
    Review the invoice details, then click **Send** to deliver it to your customer by email. Avstarna handles email delivery — no separate email setup required.
  </Step>
</Steps>

<Tip>
  Configure your payment terms and VAT settings once in **Invoice Settings** and they will be applied automatically every time you generate a new invoice.
</Tip>

## Downloading Invoice PDFs

Every invoice, credit note, and packing slip in Avstarna has a dedicated PDF that you can download, print, or share directly from within the Finance section. PDFs are generated on demand and always reflect the current state of the document.

## Credit Notes

If you need to reverse or partially refund an invoice, issue a credit note directly in Avstarna.

<Steps>
  <Step title="Locate the original invoice">
    Find the invoice you need to credit in the Finance section under **Admin → Reports → Finance → Invoices**.
  </Step>

  <Step title="Create the credit note">
    Select **Create Credit Note** and specify the lines or amounts to credit.
  </Step>

  <Step title="Send to the customer">
    Send the credit note by email in the same way as an invoice. Your customer receives a clear document referencing the original invoice.
  </Step>
</Steps>

## Financial Mutations

The Mutations section under **Admin → Reports → Finance → Mutations** records the financial transactions synced between Avstarna and your accounting software. Use the mutations log to:

* Reconcile your Avstarna records against your accounting system
* Trace the history of a specific customer account
* Provide an auditor with a complete transaction trail

## Finance Settings

Before you start sending invoices, visit **Admin → Reports → Finance → Invoice Settings** to configure:

* **Terms of payment** — set your standard payment deadline (e.g. 14 days, 30 days)
* **VAT settings** — configure the VAT rates applicable to your products and services
* **Invoice and credit note number counters** — set the starting numbers for your invoice and credit note sequences

These settings are applied as defaults whenever you create a new invoice, saving you time and reducing the risk of errors.

## e-Boekhouden Integration

If you use e-Boekhouden for your Dutch accounting, Avstarna can sync your financial data directly, eliminating manual exports.

<Note>
  e-Boekhouden is a Dutch accounting software platform. This integration is primarily relevant for businesses operating in the Netherlands.
</Note>

The integration syncs the following data between Avstarna and e-Boekhouden:

* **Invoices** — new invoices created in Avstarna are pushed to e-Boekhouden automatically
* **Credit notes** — credit notes are synced to keep your accounting records accurate
* **Mutations** — financial transactions are reflected in your e-Boekhouden ledger
* **Relations** — supplier and customer contact records are kept in sync
* **Ledgers** — chart of accounts entries are reconciled between both systems

<Warning>
  Before enabling the e-Boekhouden sync, ensure your VAT settings and ledger codes in Avstarna match the configuration in your e-Boekhouden account. Mismatches can cause sync errors that require manual correction.
</Warning>
