Platform overview
Everything Synplex does for your Shopify store
Synplex is a Shopify-native inventory platform. Every feature below connects directly to your store — no manual imports, no reconciliation, no switching tools.
One platform, every inventory workflow
Most Shopify merchants spread inventory work across Shopify itself, spreadsheets, and one or two external tools — none of which talk to each other. Synplex replaces that stack with a single system that runs on top of your Shopify data.
Every feature below reads from Shopify in real time. When you receive stock, place a purchase order, or move inventory between locations, everything stays in sync automatically.

The problem
Inventory management shouldn't require five tools
Most Shopify brands patch together their inventory workflow from Shopify's native features, spreadsheets, and standalone tools. The result is manual reconciliation, delayed decisions, and errors that compound over time.
01
No forward-looking signal
Shopify shows you what stock you have today. It can't tell you when you'll run out, what to order, or how much — leaving you reactive instead of planned.
02
Purchase orders live in email
Without a proper PO system, ordering is tracked across email threads and spreadsheets. Landed costs, shipment status, and payment terms are scattered everywhere.
03
Supplier data doesn't connect
Lead times, MOQs, and unit costs live in supplier price lists — separate from the inventory data you actually make decisions with.
All Synplex features
Every feature has a dedicated page with a full breakdown — what it does, worked examples, and how it connects to the rest of the platform.
