B2B / trade designer programs?

Native Magento B2B (or Open Source + extensions) handles trade programs cleanly:

• Trade application — custom form captures business name, license number, resale-certificate upload, portfolio URL. Submission triggers an admin notification; manual approval flips the customer’s group to “Trade.”
• Tier pricing — customer-group price rules give Trade members 15-30% off retail (your call), with deeper tiers (e.g. 35% at Diamond) gated by annual purchase volume. Enforced at cart by Magento’s native pricing engine.
• Hidden trade catalog — segment-restricted categories let you stock items only Trade members see (e.g. wholesale-only fabrics, designer-only finishes).
• Net-30 invoicing — via Apruve / Resolve / TreviPay payment-method extensions. Customer checks out without a card; invoice sent post-shipment.
• Designer rebate program — track lifetime trade purchases via custom customer attribute. Issue quarterly rebate via store credit (Mageworx / Mirasvit credit extension) or check.
• Volume-tier discounts — cart-level rules (e.g. 10% off at $5k cart, 15% at $10k) layer on top of tier pricing.
• Line-sheet PDF export — trade members generate a branded PDF of selected products via a custom “export selection” action.

Adobe Commerce ships Companies + Quotes natively; Open Source needs Aheadworks B2B Suite or equivalent.
