We are considering bringing over our store to Shopify from 3dcart. Our current plan costs us $200 a month. The Shopify Plan is $300 + 0.5% of outside payment sources. We have better rates with our payment host than shopify offers at 2.4%.
The problem is the 0.5% upcharge for using other payment hosts will cost us thousands. I am unsure if moving to Shopify will lead to more growth over 3dcart.
