Corporate Q4 surge, multi-recipient orders, custom messages, and bulk PO uploads. How?

Corporate gifting is a different ecommerce shape entirely. One order, 400 recipients, 400 different addresses, 400 personalized messages, one PO number, one invoice. Native Magento doesn’t do this; Harry & David and Williams Sonoma built it custom. The pattern I ship:

• Multi-address cart, Magento has native multi-shipping on quote, but the UI is painful. I replace it with a CSV upload flow: corporate buyer downloads a template, fills in recipient name, address, gift message, optional SKU override, uploads back. Magento parses, validates, splits into N shipments under one quote.
• Gift-message field per line item, native Magento gift-message API at item level, surfaced in the CSV column. Printed on the packing slip, not the invoice.
• Net-30 invoicing + PO numbers, corporate buyers don’t pay by card. Routes through Apruve or TreviPay (underwrite the credit, pay you day 1) or via the Adobe Commerce B2B Companies module if you’re licensed.
• Q4 capacity planning, Q4 is 50-70% of annual revenue for most gourmet brands. Magento hosting must be pre-scaled for 8-12x base traffic Nov 15, Dec 22. Cron-warmed Hyvä cache, CDN-served images, pre-rendered category pages. I run a war-room playbook every Black Friday and every Dec 15-20 corporate-gifting wave.

The corporate-portal piece (login, saved address books, repeat-order templates) is worth $25k, $60k of custom build for any brand where corporate gifting is >30% of Q4.
