The Payment Card Industry Data Security Standard (PCI DSS) is a set of requirements created to ensure that all companies that process, store, or transit payment information are securely maintained.
If you accept payments online, you are REQUIRED to be PCI Compliant. Honestly, it can be a pain ensuring that your server and your business are compliant, and it’s a huge benefit to a business to not have to deal with it.
Level 1 (of 4) is the highest compliance level, for merchant providers that process over $6 million / year in VISA transactions.
It’s a tie. Both Shopify and Lemonstand are both Level 1 compliant and take care of everything regarding PCI Compliance for your business.
