Trade-pro account verification (electrician, plumber, contractor license) + tax-exempt + Net-30, how does it work?

Three pieces wired together:

• License verification: customer uploads a state-issued license PDF at signup. For automated checks, integrate state license lookup APIs, California (CSLB), Texas (TDLR), Florida (DBPR), New York (DOS) have public APIs; smaller states require manual review. Verification turnaround: 5 minutes (automated) to 3 business days (manual).
• Tax-exempt cert: customer uploads resale certificate (state-specific form). Admin reviews and stores the cert PDF. On approval, Magento customer-group flips to “Pro”, which has tax-removed at checkout via TaxJar / Avalara rules. Annual re-verification sweep so expired certs don’t leak tax-free purchases.
• Net-30: route invoicing through Apruve, Resolve, or TreviPay. They underwrite the credit (you get paid day 1, they collect from the customer day 30), fee ~2.5-3.5% per transaction. Cheaper than carrying receivables yourself + zero bad-debt risk.

Pro group flip unlocks: trade pricing tier (typically 10-25% off retail), Net-30 checkout option, tax-removed, bulk pricing tier visibility, and access to hidden contractor-only catalogs (e.g. industrial-grade Hilti, Snap-on dealer-only SKUs).

Cuts pro-acquisition friction roughly in half vs. mailing a paper W-9 + waiting a week. Adobe Commerce B2B Companies module handles this natively; Open Source needs ~$1,500, $3,000 of extension + custom work.
