Square's API only allows Square to tokenize/store cards, which would make an integration to Billsby complicated. Nearly all major gateways offer multiple ways - including a direct API - for their customers who handle PCI themselves. Since we store card details in the Billsby Vault, any integration with Square would be incompatible with a number of our services and would make it harder for you to switch gateways in the future.

Unless this changes, we're unlikely to be able to deliver this integration.

Would love a square integration, especially something that plugged in well to their new sites feature from their purchase of weebly.
