CPGComing Soon
Marketplace Sync
Sync Shopify orders and inventory with wholesale marketplaces in real time. Two-way sync prevents overselling, automates order routing, and keeps stock levels accurate across every sales channel.
What is Marketplace Sync?
Marketplace Sync keeps your Shopify inventory and wholesale marketplace listings in perfect sync in real time, so a unit sold on Shopify immediately decrements across every marketplace — no more overselling, no more manual inventory updates, no more canceling orders because two channels thought they had the same unit. It routes incoming wholesale orders into your fulfillment workflow, matches SKUs automatically across channels, syncs tracking numbers back to each marketplace when orders ship, and gives you a single dashboard for orders from every sales channel. Built for CPG operator founders and small brands scaling wholesale alongside DTC, where manual inventory management starts breaking as soon as you're on more than two channels at once. Currently in development; request beta access to get notified when it launches.
Key Features
Who it's for
- CPG brands selling on Shopify plus one or more wholesale marketplaces (Faire, Abound, Bulletin)
- Operator founders who keep overselling because marketplaces don't know what Shopify sold
- Small brands scaling wholesale without a dedicated ops hire
- Teams spending hours each week on manual SKU matching and tracking number updates
Example workflows
Onboard a new wholesale marketplace
- 1Connect the new marketplace (Faire, Abound, Bulletin, etc.) via OAuth.
- 2Let Starch auto-match SKUs from the new marketplace to your Shopify catalog.
- 3Manually resolve any SKUs Starch couldn't match (usually different product IDs across channels).
- 4Set safety stock buffers per SKU to avoid overselling the new marketplace.
- 5Activate the sync; Starch begins flowing inventory updates immediately.
Catch and fix a sync drift
- 1Starch alerts you when a SKU's Shopify and marketplace inventory numbers don't match.
- 2Open the SKU and review the last 24 hours of activity across all connected channels.
- 3Identify the cause — usually a manual override on one channel or a timing mismatch.
- 4Trigger a forced resync to realign the numbers, then set a rule to prevent the same drift from recurring.

Frequently asked questions
When does Marketplace Sync launch?
Currently in development. Request beta access at starch.site and we will notify you when it is available. We are building this based on real operator founder feedback — if you have specific needs, tell us during the beta signup.
Which marketplaces does it support?
Shopify is the required hub, plus major wholesale marketplaces: Faire, Abound, Bulletin, RangeMe, and a few smaller ones. New marketplaces are added based on customer demand — if you're on one we don't support yet, let us know.
What is 'two-way sync'?
Inventory changes flow in both directions. A sale on Shopify reduces stock across every marketplace, and a sale on Faire reduces stock on Shopify and the other marketplaces simultaneously. Every channel sees the same number within seconds — not the next time someone clicks 'sync' on a spreadsheet.
How does it prevent overselling?
You can set safety stock buffers per SKU or per channel, so Marketplace Sync holds back a configurable amount from marketplace listings. For high-risk items, you can set stricter rules that kick in once inventory drops below a threshold. The goal is that no marketplace ever sees inventory you can't actually ship.
What about SKU mismatches between channels?
Marketplace Sync flags SKUs that don't map cleanly across channels (different product IDs, naming conventions) and lets you manually map them once. After that, sync is automatic and the mapping is remembered.
Does it handle fulfillment, or just inventory?
Inventory sync, order routing, and tracking number sync — not physical fulfillment. You still use your 3PL or in-house ops team to actually pick, pack, and ship. Marketplace Sync eliminates the manual coordination work around those physical steps.
Does it replace ShipStation or ShipBob's inventory features?
No, it complements them. ShipStation handles shipping labels and carrier integration. ShipBob handles warehousing. Marketplace Sync sits above both, ensuring your inventory numbers match across selling channels — which is a problem neither ShipStation nor ShipBob fully solves on their own.
