The Scenario
You are a catering manager. Next week you have 25 client inquiries sitting in a Google Sheet, each one a potential event booking. Each row has a different combination of line items: menu selections identified by Square catalog item IDs, quantities, a discount code, and an applicable tax rate.
You need a price quote for each combination — subtotal, discount applied, tax, and grand total — before you follow up with any client. But you do not want to create 25 actual Square orders just to get a number. Square's order calculation endpoint runs the pricing logic without creating a live order.
The manual version:
- For each row, read the line items, quantities, discount, and tax
- Open Square's API docs to look up the calculation endpoint format
- Write a one-off API call or use the developer console
- Read the response, find the subtotal, discount, tax, and grand total
- Type those four numbers into the sheet
- Twenty-five times. Two hours later you have price quotes, no clients called.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Google Sheet that reads each row of line items, calls Square's order calculation endpoint, and writes the price breakdown back into the sheet — without creating any live orders.
Open the SheetXAI sidebar and type:
For each row in this sheet (columns: item ID in column A, quantity in column B, discount code in column C, tax rate in column D), call Square's order calculation endpoint and write the calculated subtotal, discount amount, tax amount, and grand total into columns E through H. Do not create any live orders.
SheetXAI reads each row, formats the order calculation request with the line items, discount, and tax from the columns, calls the endpoint, and writes the four pricing fields back. Twenty-five rows, twenty-five price breakdowns, no Square orders created.
What You Get
A sheet with 25 rows of price quotes:
- Column E: subtotal — pre-discount, pre-tax line item total
- Column F: discount amount — the discount applied from the code in column C
- Column G: tax amount — calculated at the rate in column D
- Column H: grand total — what the client would actually pay
No live orders. Square's calculation endpoint is read-only for pricing. The quotes are accurate to what Square would charge if the order were placed — same pricing rules, same discount logic, same tax calculation.
You now have 25 price quotes ready for follow-up, formatted in the sheet alongside the client details.
What If the Data Is Not Quite Ready
Catering inquiry sheets are rarely formatted for a clean API call. SheetXAI handles the variations in the same prompt.
When some rows have multiple line items per cell
The line item column has values like "ITEM001 x2, ITEM002 x1" instead of separate rows per item.
Before calling the calculation endpoint, parse the line items in column A — each entry is a comma-separated list of item IDs and quantities. For each row, call Square's order calculation endpoint with all line items from that cell and write the subtotal, discount, tax, and grand total into columns E through H.
When discount codes are missing for some rows
Some inquiry rows have no discount code. You want the calculation to run without a discount rather than erroring on a blank cell.
For each row, call Square's order calculation endpoint using the item ID in column A and quantity in column B. If column C has a discount code, apply it. If column C is blank, run the calculation without a discount. Write subtotal, discount amount, tax, and grand total into columns E through H.
When you want to compare prices with and without the discount
Your sales team wants to see the full price and the discounted price side by side.
For each row in this sheet, run Square's order calculation endpoint twice: once with the discount code in column C applied, and once without. Write the full price subtotal and grand total into columns E and F. Write the discounted subtotal and grand total into columns G and H. Write the savings amount (column F minus column H) into column I.
When you need to calculate prices, rank quotes by margin, and flag high-discount rows in one shot
You want the price breakdowns but also a margin analysis so you know which bookings to prioritize and which are giving away too much.
For each row, call Square's order calculation endpoint with the line items, quantity, discount, and tax from columns A through D. Write subtotal, discount amount, tax, and grand total into columns E through H. Then in column I, calculate the discount as a percentage of the subtotal. Write "Review" into column J for any row where the discount is more than 20% of the subtotal. Sort the sheet by column I descending so the highest-discount quotes are at the top.
The pattern: the calculation step and the margin analysis both happen in the same prompt. You go into the follow-up calls knowing which bookings need a conversation about pricing.
