# Billay

> Automate invoice and expense processing from capture to booking suggestion, review, approval, and accounting export.

**Billay is Layest's Invoice Agent.** It turns incoming invoices and receipts into structured accounting data, prepares booking suggestions, and gives your team a clear review step before anything is approved or exported.

Billay is designed for bookkeepers, accounting teams, tax advisors, and operations teams that want faster processing without giving up control.

## From invoice to approved booking

<Steps>
  <Step title="Receive the invoice">
    Start manually with uploaded files, use a dedicated email inbox, or connect a folder for recurring intake.
  </Step>

  <Step title="Extract the details">
    Billay reads the document and prepares structured invoice information, including the fields used in your accounting workflow.
  </Step>

  <Step title="Prepare the booking suggestion">
    The agent uses the managed invoice records and Chart of Accounts to support account assignment and booking preparation.
  </Step>

  <Step title="Review and approve">
    A reviewer checks the invoice, corrects any details, and approves or rejects the draft. The source remains linked to the run.
  </Step>

  <Step title="Export when ready">
    Approved, not-yet-exported invoices can be included in an accounting export. BMD exports are created as ZIP files and remain available in Layest Files.
  </Step>
</Steps>

## Your Setup page

Billay is ready to run quickly because Layest provides the core accounting collections.

* **Manual uploads** are included.
* **Invoice records** are stored in a Layest-managed Data Collection.
* **Chart of Accounts** is included and starts with Austrian standard accounts that your team can adapt.
* **Email intake** is recommended for a simple invoice address.
* **BMD export** is recommended when your accounting process uses BMD.
* **Schedules and connected folders** are optional ways to automate intake.
* **External destinations** are optional for approved files or results.

<Info>
  Recommended and optional setup never blocks a manual run. Billay can be ready while still showing useful decisions such as email intake or ERP export.
</Info>

## Reviewing invoices

A good review checks more than whether text was recognized. Confirm that:

* supplier or customer information is correct
* invoice number and dates match the document
* net, tax, and gross amounts are consistent
* currency and payment details are complete
* the suggested accounts fit your accounting policy
* the source PDF belongs to the structured record

If a draft needs more work, correct it directly or re-extract from the source. Rejecting a draft does not import the records and keeps the run available for follow-up.

## BMD export

Billay can create a BMD-compatible ZIP for approved bookings that have not yet been exported.

Before the first export:

1. review the managed general and subsidiary ledgers
2. confirm the account mapping used for Konto and Gegenkonto
3. choose manual export or add a reusable schedule
4. optionally add an external delivery destination
5. review the eligible and excluded invoice count before creating the archive

Previous export history remains visible, and generated ZIP files are saved in Layest Files.

<Note>
  Other ERP systems may appear as previews in the product. Only configure and document an export as active when the Setup page allows you to complete it.
