Cin7 Omni vs Sentry WMS

Cin7 Omni is inventory and order management software for businesses managing sales across multiple channels. It provides a real-time view of inventory across locations and supply chains, with barcode scanning, stock alerts, purchase orders and sales orders. Purchase orders can sync automatically with linked 3PLs, and 3PL integrations support automated order fulfillment. Native EDI connections support supply-chain and sales-channel workflows. Cin7 connects with Shopify, WooCommerce, Amazon, QuickBooks, Xero and other platforms, and its app ecosystem includes more than 700 partners. The Omni comparison lists eight users, with more available for purchase, and unlimited inventory locations. Customizable workflows support online, wholesale and retail markets; multi-entity support automates intercompany stock and price adjustments. It runs on web, iOS and Android. A free trial is offered, but there is no free plan. Standard starts at $349 per month, Pro at $599 per month and Advanced at $1,199 per month, excluding taxes. Custom solutions are available for complex operations or needs beyond standard configuration.

Sentry WMS is a free, self-hosted warehouse execution system for e-commerce businesses that already use a system of record or ERP. It handles receiving, storage, picking, packing, shipping, and counting, including multiple warehouses. Teams can batch orders for picking with serpentine walk-path optimization. Inventory tools include bin-level cycle counts with variance detection and admin approval, plus adjustments and transfers. Barcode lookup from the mobile app home screen can identify items, bins, purchase orders, or sales orders. An inbound API accepts updates for sales orders, items, customers, vendors, and purchase orders using source-specific YAML mappings and scoped WMS tokens. Its connector framework is intended for ERP and commerce platforms, but operators or developers must build the connectors; first-party ones are planned for v2.0.0. The documented deployment uses Docker Compose, a Flask API, PostgreSQL 16, a React admin panel, and a React Native Expo mobile app. The public project is under Apache-2.0 and documents encrypted connector credentials, a hash-chained audit log, and SSRF protections.
