After the sale

CDX is built so win → pay → ship → done runs with almost no staff. SpotPro dealers reuse Shippo keys and inventory. Public sellers (when opened) get the same buyer experience with clearer self-serve fulfillment blanks filled in below.

Goal: exceed generic auction sites on post-sale clarity — buyer always knows who ships, how to track, and how to open a claim; seller buys postage in one flow.

Happy path (automated where possible)

Lot closes (timer, Buy Now, or accepted offer) → invoice created; buyer notified.
Buyer pays seller (dealer rails / report offline) → fraud gates may require phone/ID.
Seller confirms offline pay if needed; card success auto-marks paid.
Ship — Buy Shippo label or enter tracking → buyer gets track link.
Delivered (tracking poll) → complete / feedback.

Shippo labels (SpotPro sellers today)

Setup

SpotPro Software → Config → API Integrations → Shippo live key (shippo_live_…). Same key as Store Orders. Seller key always wins (no platform margin).

On a CDX invoice

Seller console → Payments → Get rates → pick service → Buy label. Label PDF + tracking saved; status → shipped.

Print

Default 4×6 PDF for thermal printers (configurable in SpotPro Software). Open Print label on the invoice card. Batch: check invoices → Batch labels / Packing slips.

Platform Shippo + postage wallet (testable; not public ungate)

If the seller has no Shippo key, rates/buy can use the platform key (~/.config/cdx-platform-shippo.php) with a configurable margin and a per-seller postage wallet. Test mode allows wallet top-up (and negative balance) so you can exercise the path without a card. Does not open the seller allowlist.

Console: Payments → Fulfillment tools → wallet balance / Test wallet +$
Packing slip: per-invoice link or batch checkboxes → PDF (Dompdf)
Batch labels: only invoices that already have a purchased label_url

Tracking

Carrier deep links always (USPS/UPS/FedEx/DHL heuristics).
Shippo track status when seller has a key (cron + refresh).
Buyer sees tracking on account payments / win details.
Manual tracking still supported for carriers bought outside Shippo.

Claims (anti-fraud aware)

Structured claims: not received / wrong item. Tracking evidence required. No auto-reship. Seller responds in console; evidence windows enforce waiting after ship / after delivered.
