I was planning on having my online store website through Shopify - does that make Shopify my default POS? Or are other POS’s compatible with a Shopify online store? Next, I was planning on using Wave’s free accounting. If Wave connects to my business bank account (for free I’m assuming) & I roll with Shopify POS - are there any other considerations I’m leaving out to be covered in general/organized for tax time?

Thanks in advance!
