The Scenario
You run the billing operation for a 30-person creative agency. Every month, 50 client retainers need to be invoiced in Xero. The billing data — client contact ID, service description, amount, account code — lives in an Excel workbook your ops team maintains. Someone enters it fresh each month. Xero, however, is empty until you create each invoice by hand.
Last month it took you four hours. You made seven errors. Three clients got the wrong account code.
The bad version:
- You open Xero's invoice screen and start entering the first row: contact, description, amount, account code, due date — save, next
- Around invoice 15 you realize you misread a row from the Excel table and entered the wrong amount — you go back to fix it and lose your place
- You finish all 50 invoices at 6 PM, discover two clients share almost identical names and you invoiced the wrong entity for one of them, and have to void the invoice and start over
Fifty is exactly the number that makes manual entry feel unreasonable and automation feel urgent.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads the billing table and creates every Xero invoice in one operation — no UI clicking, no row-by-row entry.
Open your billing workbook and try this prompt:
Create a Xero invoice for each row in the Billing worksheet starting at row 2 — column A is contact ID, column B is line item description, column C is unit amount, column D is account code — set due date to 30 days from today and status to AUTHORISED
What You Get
- One Xero invoice per row, with the contact, description, amount, account code, and due date from your workbook
- Any row where the contact ID does not match a Xero record surfaces in a Status column — so you know which ones need attention
- Errors are reported with reasons, not silently skipped
- Successfully created invoices get their Xero invoice number written back into a result column
What If the Data Is Not Quite Ready
The worksheet uses contact names, not contact IDs
For rows 2 through 51 in the Billing worksheet, look up each contact name in column A against Xero contacts, resolve to the contact ID, then create a Xero ACCREC invoice using the resolved ID, description from column B, amount from column C, and account code from column D
Some clients have multiple line items — one client, several service rows
Create Xero invoices grouped by client name in column A — combine all rows with the same client into one invoice, with each row becoming a separate line item using description from column B, amount from column C, and account code from column D
You want invoices in DRAFT status before authorising
Create Xero invoices for rows 2 through 51 in the Billing worksheet using contact ID from column A, description from column B, amount from column C, account code from column D — set each invoice to DRAFT so I can review before sending
Validate completeness, flag problem rows, then create all clean rows
Check the Billing worksheet for rows where column A, B, C, or D is blank — write "Missing data" in column E for those rows — then for all rows where all four columns are populated, create a Xero ACCREC invoice and write the resulting invoice number into column E
One prompt handles the validation, the creation, and the writeback.
