PARTS sits at the center of your business. Marketplaces orbit around it — inventory and orders flow in, your decisions flow out.
Each storefront is a spoke on the wheel. Connect two, four, or as many as your plan allows — PARTS keeps them all pointed at the same truth.

Most sync tools either overwrite blindly or drown you in warnings. PARTS does neither — it queues the disagreement and asks you to decide.
A marketplace says 5, PARTS says 3? That's a conflict. It lands on the Review page with both values side by side, instead of one silently winning.
Keep yours, take the marketplace's, or dismiss — every resolution is recorded with who decided and when. Full audit trail, zero mystery edits.
When an order lands, PARTS holds the stock immediately. If a buyer wants more than you have, the shortage is flagged — not silently oversold.
Every plan syncs automatically. Here's exactly what each plan gives you:
The sync engine is channel-first. BrickLink and Brick Owl connect right from the Marketplaces page — connect your accounts and review the imported inventory before enabling stock publishing, with more coming all the time.
Go to Marketplaces, pick your platform, paste your API credentials, and sync. Your listings appear in PARTS — the whole connection takes about two minutes per marketplace.
