# AI Invoice Parser

> Utilize the **PDF.co** AI Invoice Parser to automatically detect invoice and structurally extract data with our advancedu AI. The AI Invoice parser automatically detects invoice layouts without the manual effort previously required to supply document parsing templates for reference.

<Warning>
  **Important**

  * **Only invoices will be parsed**. For all other documents, please use our existing [**Document Parser**](/integrations/make/document-parser).
  * To ensure accurate processing, each invoice must be clearly separated. **If an invoice contains multiple pages, we recommend splitting it** into individual PDFs using the [PDF Split ](/integrations/make/split-pdf)node in your workflow.
  * While AI Invoice Parser supports multi-page invoices, **the total page count for a single PDF must not exceed 100 pages**. Submitting large PDFs containing multiple invoices is not recommended.
</Warning>

| **customField**       | Comma-separated list of [custom field](/integrations/make/ai-invoice-parser#custom-fields) names to extract. Use `camelCase` for field names (e.g., `storeNumber`, `deliveryDate`).                             | No       |

| **Webhook URL**       | The callback URL or Webhook used to receive the output data.                                                                                                                                                    | No       |

### Integrating External File Sources

<Note>
  Streamline your **Make** workflows with external file sources like **Google Drive** and **Dropbox** using their unique actions. Discover efficient integration strategies in our guide: [File Source Integrations in Make](/integrations/make/input-file-sources).
</Note>

### Custom Fields

AI Invoice Parser with custom fields support automatically detects invoice layouts and extracts both standard schema data and user-specified custom fields without requiring manual templates.

The `customField` parameter allows you to specify additional fields to extract beyond the standard schema. Some examples include:

* `storeNumber` - Store or branch identifier
* `deliveryDate` - Expected delivery date
* `financialCharges` - Additional financial charges
* `lineTotal` - Total amount for line items
* `purchaseOrderRef` - Purchase order reference number
* `customerReference` - Customer reference number
* `departmentCode` - Department or cost center code

<Note>
  If a custom field returns an empty value, please [contact our support team](https://pdf.co/support/request?subject=ai-invoice-parser%20-%20custom%20fields) to help improve the extraction accuracy.
</Note>

### Line Item Structure

The `lineItemStructure` parameter lets you define a custom schema for line items. Each key is a field name you choose (in `camelCase`) and each value is the expected data type — either `"string"` or `"number"`.

When provided, every object inside the `lineItems` array will contain exactly the fields you specified. If a value cannot be extracted from the invoice, the field will still be present with an empty or default value instead of being omitted.

<Note>
  Use `camelCase` for field names (e.g., `unitPrice`, `totalPrice`). The field names you define will be used as-is in the response, giving you full control over the output keys.
