# Connect Paige to SAP Business One

Two working paths from Paige into SAP Business One: the Data Transfer Workbench to load a batch of A/P invoices from Paige's CSV, or an integration with the Service Layer that creates each A/P invoice and attaches the PDF. Which to pick, what lands in SAP B1, and the step-by-step guides.

**Paige reads the invoice — vendor, invoice number, dates, total, even handwritten ones — and SAP Business One gets the A/P invoice, with the PDF attached, without anyone keying it in.**

SAP Business One (SAP B1, "SAP" at most small and mid-size companies that run it) loads data two ways from outside: the **Data Transfer Workbench** (DTW) for files, and the **Service Layer** API for integrations. Paige's export feeds either.

## What lands in SAP Business One

|  | Data Transfer Workbench | Service Layer integration |
| --- | --- | --- |
| An **A/P invoice** per invoice | Created when you run the import, in batches | Created minutes after Paige finishes the invoice |
| Vendor, dates, vendor reference, service line account and amount | From Paige's CSV via DTW's Documents and Document_Lines templates | From Paige's fields |
| The **PDF attached** | No — attach by hand on the invoice's Attachments tab | Yes — uploaded to Attachments2 and linked on the invoice |
| Who does it | An SAP B1 administrator or key user | A developer |
