AI Chat Sorted My Yearly Orders

I exported last year's 212 Stripe orders to a CSV. An AI chat grouped them by month and VAT rate for the bookkeeper.

Saved an evening: it counted two refunds as sales, so I checked totals by hand.

Cheers

For our own bookkeeper last year!

I took the names and addresses out of the export before it went anywhere near the chat.

Checking totals by hand is the bit I'm curious about. Against what, though? Stripe's own monthly figures, or just adding the CSV up yourself?

If the chat quietly counted two refunds as sales, it could have dropped an order under the wrong VAT rate just as quietly.

And a monthly sum would never show that.

I checked the whole year against the shop's own sales report and the bank (both to the euro). Then did one month by hand.
