# Upload a purchase invoice or receipt

> Uploads one PDF, UBL, PNG or JPG file to Inkopen for SnelStart to read. Input schema, a tools/call example and an example result.

Source: https://cotlet.dev/docs/mcp/snelstart/upload_purchase_document

Docs sections: [Get started](https://cotlet.dev/docs.md) · [REST API](https://cotlet.dev/docs/api.md) · [MCP](https://cotlet.dev/docs/mcp.md) · [SDKs & CLI](https://cotlet.dev/docs/sdks.md) · [Integrations](https://cotlet.dev/docs/integrations.md)

Uploads one PDF, UBL, PNG or JPG file to Inkopen for SnelStart to read.

SnelStart MCP tools: https://cotlet.dev/docs/mcp/snelstart.md

MCP tool: `snelstart_write → upload_purchase_document`

Access: write.

Does what dragging a file into Inkopen does. SnelStart reads the file and lists it as a purchase with status Te controleren, with the date, amount and supplier it recognised. Recognition is not 100 percent accurate, and the purchase stays on Vraagposten until a cost account is set. The upload reaches no one and books nothing final, so it does not ask for confirmation.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `file_name` | string | yes | File name with extension: pdf, xml (UBL), png, jpg or jpeg. |
| `file_base64` | string | yes | File contents, base64 encoded. |

1. Read the fields and their allowed values: GET https://cotlet.dev/api/v1/access-requests
2. Ask the user for each value: email, apps, what you will do with them. If they leave the password to you, generate a strong one and show it to them.
3. Show the user what you will send, then POST it as JSON to https://cotlet.dev/api/v1/access-requests.
