I have multiple sales using woocommerce that I would like to add to wave.
As there is no woocommerce integration with wave what is the best way to at sales from my website to wave?
As far as I know, @Will_Brett, you can't.
It's been a bit since I used woocommerce, but I think you can get your export your order in a CSV, no? If you can, you could start with that, turn it into a bank statement like the ones you upload to Wave and upload that. You'll have to force everything into 3 columns and it'll be a bit of work, but it'll do the trick.
You may find what you are looking for in this integration... https://zapier.com/apps/wave/integrations/woocommerce
There's a WordPress plugin for that: https://codecanyon.net/item/woocommerce-wave-connector/25870114
