Transform your e-commerce fulfillment with String, the comprehensive order management and shipping optimization platform that seamlessly integrates with ShipStation
Automatically compare rates across all your carriers to find the best shipping options for every order. Our advanced algorithms consider delivery time, cost, and service reliability to maximize margins while meeting customer expectations.
Our sophisticated packing algorithms automatically determine the optimal box size and configuration for each order, reducing shipping costs and minimizing dimensional weight charges.
Intelligently manage orders waiting for inventory with automated hold and release workflows. Orders are automatically tagged and held when inventory is unavailable, then released for fulfillment once stock arrives - eliminating manual tracking and reducing fulfillment delays.
Automatically split orders requiring multiple packages into separate shipments while maintaining complete tracking visibility. Perfect for large orders that exceed single-box limits or require special handling for different product types.
Seamlessly separate pre-order items from in-stock inventory, creating separate orders to ship available items immediately while holding pre-orders until release date. Keep customers happy with faster partial fulfillment.
Intelligently group single-SKU orders into optimized batches for efficient pick-and-pack operations. Reduce warehouse walking time and increase fulfillment speed by processing similar orders together.
Compare shipping rates across all your warehouse locations to fulfill from the optimal facility based on cost, delivery time, and inventory availability.
