Dear @Chrischurch1 ,
We are a Shopify partner and an application developer. As an organisation, we are specialised in integrating third party payment gateways/Payment processors into Shopify stores.
Unfortunately, each Shopify Merchant must find a suitable payment processor and signup directly if they wish to process EBT/SNAP payments. Once this step is completed, you will need to complete payment processor integration process through us or with any other application development agency.
