How to add an invoice

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.

Written by Stacey Breyer

Step 1: Confirm the Work Order is Complete

Before submitting an invoice, confirm that the work order has been completed.

From the Overview tab of the work order:

  • Check in to the job

  • Check out of the job

  • Mark the work order Complete

Also confirm the invoice amount is within the NTE (Not-To-Exceed) amount.


Step 2: Navigate to the Invoices Tab

Inside the work order, click the Invoices tab.

This is where invoices are uploaded and reviewed before submission.


Step 3: Upload the Invoice

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

Supported formats typically include:

  • PDF

  • Image files

  • Scanned invoices


Step 4: 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 5: 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 6: Create the Invoice

Once all information looks correct:

Click “Create Invoice”

This will generate the invoice within the work order.


Step 7: Publish the Invoice (Important Final Step)

After creating the invoice, it will remain in Draft Status.

To submit it for approval:

Click “Publish Invoice”

Once published, the invoice will move to Pending Status and be sent to the customer for approval.


Final Result

Your invoice is now submitted and awaiting approval.

Benefits of AI Invoice Upload:

  • No manual charge entry

  • Faster invoice submission

  • Accurate expense categorization

  • Better maintenance spend tracking
