It integrates with major ERPs and e-commerce platforms (Magento, WooCommerce, BigCommerce) and is used to automate accounts receivable and payable for mid-market and enterprise finance teams.

PayStand publishes 1 API on the APIs.io network. Tagged areas include Company, Payments, B2B Payments, Accounts Receivable, and Accounts Payable.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
