Desktop inventory-management programs can cost thousands of dollars. New online platforms let you manage orders and inventory from any Web browser for a low monthly fee. Here are two options to suit different needs.

Best for Online and Offline Stores
Stitch Labs

This service lets you manage orders, contacts, inventory, and packing slips on a colorful online dashboard. A good choice for businesses with both online and offline stores, it works with several major e-commerce platforms, including Shopify and PayPal, as well as Sail by VeriFone, a mobile payment system for iPhones, iPads, and Android devices. When you make a sale, Stitch automatically updates inventory levels in real time.
Cost: Free for one sales channel (an online store, for instance), then $25 a month for unlimited channels

Best for Streamlined Shipping
Ordoro

Exclusively for online stores, Ordoro works with several e-commerce platforms, including eBay and Shopify. The service lets you manage inventory and orders using an online dashboard. You can sync it with your FedEx, UPS, and USPS accounts and print shipping labels customized with your logo. It also supports drop shipping from a wholesaler or manufacturer. Unlike Stitch, Ordoro can track one item with multiple components.
Cost: Starting at $19 a month for one store with up to 500 products
