The Scenario
You're the procurement officer. It's three days before the payment run, and you have 60 open purchase orders in Zoho Books and 45 supplier invoices received this month. Someone on the finance team flagged that two vendors might have billed more than their POs authorised. You need to match every invoice against its PO and surface any line where the bill is more than 5% over.
The bad version:
- Export the PO list from Zoho Books as a CSV, open it in Excel.
- Export the bills list separately, open that too.
- Write a VLOOKUP to match bill amounts to PO amounts by PO number.
- Discover that 8 of the 45 bills reference PO numbers with a different format than what Zoho Books exported, fix those manually.
- Add a formula to flag rows where the bill exceeds the PO by more than 5%.
The payment run doesn't wait for your VLOOKUP to work. And if a vendor overbilling slips through, the finance team finds out after the wire has already gone.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It fetches both the PO data and the bill data from Zoho Books and runs the matching logic in one step.
Pull all open Zoho Books POs into my Excel sheet with vendor name and PO amount, then flag rows where a bill exists whose amount is more than 5% higher than the PO amount
What You Get
- Columns populated: PO Number, Vendor Name, PO Date, PO Amount, Bill Amount.
- OVER-BILLED flag written for any row where bill exceeds PO by more than 5%.
- Unmatched POs (no bill found) noted as NO BILL.
- Row count and flagged count returned in a summary message.
What If the Data Is Not Quite Ready
Some bills reference PO numbers with a different prefix format
Pull all Zoho Books open POs and match to their bills, normalising PO number format by stripping any leading PO- or ZB- prefix before matching; flag OVER-BILLED where bill exceeds PO by more than 5%
You need line-item-level visibility on the overbilled rows
For any Zoho Books PO where the total bill exceeds the PO amount by more than 5%, list each line item from both the PO and the bill side by side so the discrepancy is visible at the item level
Some vendors have multiple bills against a single PO
Pull all Zoho Books open POs; for each PO sum all associated bill amounts; flag OVER-BILLED where the total billed amount exceeds the PO total by more than 5%
Full pre-payment-run check in one shot
Fetch all Zoho Books open POs, match all associated bills, sum bill amounts per PO, flag OVER-BILLED where sum exceeds PO by more than 5% and NO BILL where nothing found, sort with OVER-BILLED rows at the top, and write vendor name alongside each flag
The pattern: ask for the normalisation, the aggregation, and the flagging in a single prompt.
