Hi @adamgarnett sorry for the slow reply, missed this one before the weekend. This will depend which method of applying store credits you are using. If it’s before tax and shipping the system uses a “dynamic” coupon, so technically if you export orders, the coupon should show up and you can run a filter on that in excel or google sheets that way to perform your analysis.
If it’s applied after, this treats it more like a payment and we store meta data on the order itself to handle this called ‘acfw_store_credits_order_paid’ and you could potentially pull this out while exporting orders to find the ones with store credit used.
A third option would be to export data from the store credits table {db_prefix}_acfw_store_credits.
As for analyzing the data, if you’re able to export orders over a period you can import this into Excel or Google Sheets. Another alternative would be to check a system like Metorik who I believe can query any order meta data and coupon data (best to check in with their support though to see how this would be possible for your site… just tell them Josh at Advanced Coupons sent you over).
I hope this gives you some options to follow up!
