Stop overselling with accurate, real-time stock
Overselling happens when the number a customer sees isn't the number you have. Zync keeps Shopify and Zoho stock in lockstep so availability is always true.
Two-way sync · Zoho Books & Inventory · All 5 Zoho data centers · From $15/mo
Built for the Shopify & Zoho stack
Why overselling happens
Stale inventory is the root cause — and it compounds across locations.
- Manual updates lag behind real sales.
- Multiple locations blur true availability.
- Batch syncs leave windows of wrong stock.
- No source of truth means no one's number is right.
How Zync fixes it
Real-time, per-location sync closes the gap.
- Webhook-driven adjustments the moment stock changes.
- Per-location quantities mapped to Zoho warehouses.
- Choose Zoho as the source of truth for stock.
- Bulk reconcile to fix drift immediately.
From install to live sync
Connect Zoho
Verify your Zoho client, organization, API domain, and module — Books, Inventory, or both — via OAuth in the Shopify admin.
Map operations
Choose locations, warehouses, product rules, order rules, and customer behavior. No Zoho-side module to install.
Run queued sync
Move product, order, customer, and inventory work through retry-safe queues instead of fragile inline actions.
Monitor records
Use linked metafields and a per-record sync log to see what synced and what needs attention.
