The Scenario
Your billing manager is looking at a Google Sheet with 60 invoice IDs. They were all created last week for jobs that included a standard one-year extended warranty. The warranty line item — SKU EXT-WAR-1YR, $49 flat — needs to be added to every one of those invoices before statements go out Friday. The invoices exist in RepairShopr. The IDs are in column A. There are 60 of them.
The bad version:
- Open RepairShopr. Search for invoice 10482. Click Edit. Scroll to line items. Click Add Line Item. Search for the SKU. Set quantity to 1. Save.
- Go back to the spreadsheet. Mark row 1 as done. Open invoice 10483. Repeat.
- Hit invoice 10531 and realize you added the warranty to one invoice twice because you lost track of where you were in the list.
Sixty invoices at four minutes each is four hours of an afternoon that should have been spent on something else.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Google Sheet. It reads the invoice ID list, understands the task, and through its built-in RepairShopr integration it can add the line item to all 60 invoices in one operation — writing a confirmation back into the sheet as each update completes.
Add a line item with SKU 'EXT-WAR-1YR' and price $49 to every invoice ID listed in column A of this sheet
What You Get
- The extended warranty line item added to each invoice in column A
- "Updated" written into column B for each successful addition
- Any invoice that fails (e.g., the invoice is already closed) gets the error message in column B instead
- No invoice is processed twice — the operation is scoped to the exact rows in column A
What If the Data Is Not Quite Ready
Different invoices need different line items, not all the same SKU
For each invoice ID in this sheet, add the product from column B at the quantity in column C and unit price in column D as a new line item in RepairShopr, then write the result into column E
Some invoices in column A are already paid and shouldn't be edited
For each invoice ID in column A, check if the invoice status is paid before adding the EXT-WAR-1YR line item; if the invoice is paid, write "PAID - SKIP" in column B instead of adding the line item
The invoices belong to different customers and you want the customer name logged alongside the result
Add SKU EXT-WAR-1YR at $49 to each invoice ID in column A; write the customer name and result into columns B and C so you have a log of who was charged
Full line-item batch in one pass: check status, add item, log customer, flag errors
For each invoice ID in column A, check if the invoice is in an editable state; if yes, add EXT-WAR-1YR at quantity 1 and price $49, write the customer name into column B and "Added" into column C; if the invoice is paid or closed, write "SKIP" in column C; if the addition fails, write the error and mark column D "NEEDS MANUAL REVIEW"
The pattern: describe the guard conditions in the prompt so the batch operation completes cleanly without leaving you to manually audit which invoices were actually updated.
