One stock ledger
Storefront, POS, buylist, and marketplace listings all draw from the same inventory record. When a card sells in one place, the available quantity is reduced everywhere else instead of waiting for staff to remember a manual update.
Cardtrader

Operations
How Cardtrader fits into one inventory source
Marketplace sync is only useful if staff can trust the numbers at the counter. Storefront Pro treats each channel as an output of the same stock ledger, not as a separate spreadsheet to reconcile later.
Channel-specific rules
Your own storefront can hold margin while marketplace listings compete more aggressively. Pricing rules can reflect fees, shipping expectations, condition, language, and how quickly you want a particular catalogue to move.
Order reconciliation
Orders from external channels are pulled into the same fulfilment queue as online and in-store sales. Staff pick, pack, refund, and report from one place instead of switching between seller portals.
Exception handling
API limits, rejected listings, missing SKUs, and price-rule conflicts are visible in the admin dashboard. The integration is designed to make failures obvious, because silent sync failures are how oversells happen.
Limitations
What it doesn't do
We'd rather tell you the limits before you apply than have you discover them after acceptance.
