# Transactful > Transactful is a Shopify app for credit-led B2B wholesale: buyers apply for a > wholesale account, merchants approve with a credit limit, and Shopify checkout > automatically blocks orders that would exceed the buyer's available credit. > UK and EU VAT numbers are validated at application (HMRC / VIES). Built > entirely on Shopify's native B2B platform — no theme code — and enforcement > works on every Shopify plan, including Basic and Grow (Plus not required). > Pricing starts at $49/month.
