B2B corporate gifting, bulk, Net-30, single-PO multi-recipient drop-ship. How?

Corporate gifting is the highest-margin chocolate revenue and the hardest channel to ship on Shopify. The Magento setup:

• Customer-group pricing, corporate tier: 15-30% off retail at 50+ boxes. Tiered: 50-199 boxes = 15% off, 200-999 = 20%, 1,000+ = 25%, 5,000+ = quoted. Native Magento.
• Single-PO bulk checkout, HR uploads a CSV of 200 employee names + addresses, one PO covers all 200 boxes, drop-ships individually with corporate-branded message cards. Built as a Magento extension on top of native multi-address checkout. Adobe Commerce B2B Companies handles this; Open Source needs Aheadworks B2B Suite or Amasty Company Accounts (~$1.5k one-time).
• Net-30 invoicing via Apruve, Resolve, or TreviPay, they underwrite the credit, pay you on day 1, customer pays them on day 30. ~2.5-3.5% of invoice. Standard corporate procurement expectation.
• Branded message-card overlay with corporate logo (PO-attached PDF or pre-loaded company-logo SKU).
• Recurring corporate orders, quarterly client gifting, annual employee appreciation. Magento subscriptions + reorder list.

Tony’s Chocolonely runs corporate B2B on this exact Magento pattern. See’s Candies has a separate corporate-gifting URL on the same backend. A single Fortune-500 client doing quarterly $50k orders pays for the entire B2B build inside 6 months.
