Is there a limit to the amount of sales that the spreadsheet can handle?

For v1 there is a maximum of 6000 sales a month, across 1000 unique SKU’s a month (72,000 sales total), and 5000 unique SKU’s total.

For v2 the max sales are limited by Excel (1 million rows of sales data) and your computer. If you have over 100,000 sales a year, we highly recommend 64 bit Excel and lots of memory.
