U'mista Cultural Centre review for Invoice Falcon

I used this app to pay for purchases made on an account with us through our Shopify POS store. It makes it simple and quick, and with the PO order functionality I have speed up getting paid. I reached out to the owner and I got an immediate response. He is adding a search and filter function to the invoice section soon (Dec 31, 2019), so that I can quickly find sent and printed invoices. Highly recommend!
