How to Submit an Invoice on Behalf of a Supplier

If a supplier is unable or unwilling to upload their invoice directly, you can upload the invoice on their behalf so that maintenance costs are still tracked accurately in OpenWrench.

Written by Stacey Breyer

Step 1: Confirm the Supplier is Assigned to the Work Order

Before uploading an invoice, make sure the correct supplier is assigned to the work order.

This ensures the invoice is properly tied to the supplier and the service performed.


Step 2: Navigate to the Invoices Tab

Open the work order and click the Invoices tab.


Step 3: Upload the Invoice

Click “Upload Invoice” and attach the invoice file provided by the supplier.

OpenWrench’s AI Invoice Processing will automatically extract and classify the charges from the invoice.

Step 4: Confirm Payment Status (Important)

When uploading the invoice, you will be asked to indicate whether the invoice has already been paid.

If “No” is selected

  • The invoice will move to Pending Status

  • The customer will review and approve or dispute the invoice

If “Yes” is selected

  • The invoice will skip Pending Status

  • It will move directly to Paid Status

AI Invoice Upload & Classification

Submit Invoices in Seconds with AI

OpenWrench’s AI Invoice Upload & Classification automatically reads your invoice and categorizes each line item into Labor, Parts, Tax, and Other — eliminating manual entry and making maintenance spend tracking more accurate.

Follow the steps below to submit an invoice using AI.


Step 1: Navigate to the Invoices Tab

Inside the work order, click the Invoices tab.

This is where invoices are uploaded and reviewed before submission.


Step 2: Upload the Invoice

Click “Click to Upload” and attach the invoice file.

Supported formats typically include:

  • PDF

  • Image files

  • Scanned invoices


Step 3: AI Reads and Classifies the Invoice

Once uploaded, OpenWrench AI automatically reviews the invoice and extracts the information.

The system will classify each line item into categories such as:

  • Labor

  • Parts

  • Tax

  • Other Charges

This eliminates the need to manually enter each charge.


Step 4: Review the Extracted Information

After the AI processes the invoice, you will have the opportunity to review all fields and charges.

If OpenWrench detects anything that may need attention, it will display a red alert notification.

Review and adjust any fields if necessary.


Step 5: Create the Invoice

Once all information looks correct:

Click “Create Invoice”

This will generate the invoice within the work order.
