# Uploading Documents

> How to attach supporting documents to quotes

After submitting a quote, you can upload supporting documents to provide additional context and documentation for the financing request. These attachments help ensure all necessary information is available for processing.

## How to Upload

You can upload documents in two ways:

1. **From the confirmation screen** — Immediately after submitting a quote, use the upload section on the confirmation page
2. **From the quotes table** — Navigate to the quotes list, find your quote, and click the arrow (→) button on the right to access the quote details page where you can upload documents

## Document Types

When uploading, you can categorize your document by type. This helps organize attachments and ensures the right documents are available during processing:

| Type                           | When to Use                                                                                            | Examples                                                      |
| ------------------------------ | ------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------- |
| **Quote Copy**                 | Upload the original quote document that was presented to the customer                                  | Customer-facing quote PDF, signed quote document              |
| **NWF Installer Declarations** | Upload NWF (Nationaal Warmtefonds) installer declaration forms required for Dutch subsidy applications | Completed NWF declaration PDFs, installer certification forms |
| **Invoice**                    | Upload final invoices or billing documents                                                             | Final invoice after installation, payment receipts            |

<Info>
  Document type is optional but recommended. It makes it easier to find specific documents later and helps streamline the processing workflow.

## What Happens After Upload

Once uploaded, documents are securely stored and associated with the quote. The Prets team will review these documents as part of the financing process. You do not need to take any further action after uploading.
