Shopify's native B2B handles companies and price tiers. It doesn't enforce credit limits, give buyers a self-service invoice portal, or scale past 3 catalogs below Plus. Net Terms Tracker does all three. Approve a customer for Net 15, 30, or 60. Set their credit limit. The app enforces it at checkout, generates a branded PDF invoice, and gives the buyer a Finance Portal where they pay themselves. Works alongside native B2B or on its own. Any Shopify plan.
