Nationwide field desk: WHAT to buy — your shop buys anywhere in the US.

Structured info on the topic in front of you. Candidate parts with a supplier-agnostic draft cart — copy PO/CSV/JSON and buy on any US HVAC wholesaler, plumbing supply, electrical distributor, industrial MRO, OEM portal, marketplace, or local house. No exclusive vendor lock-in. No auto-buy.

DRAFT mode US nationwide any supplier No auto-buy Human approve Cite — don’t invent

Open desk System health

Cite — don’t invent Templates never invent OEM part numbers or torque specs as fact.

Human approve Draft carts only. Your shop places the order on any US supplier account you already use.

No auto-buy Payments and supplier APIs stay gated. Approve remains inert.

Refuse engine Blocks auto-buy, license stamps, life-safety bypass, and secret requests.

Mobile + PWA shell — large taps, sticky Run, offline static cache only.

Still gated (owner)

Stripe / live payments
Supplier OAuth / order APIs / auto-buy (optional later — default forever is agnostic export)
