Order routing

Route every order to the right place

Let Charlie pick the best location for each order. Prioritize by available stock, customer proximity, or operational capacity to reduce your shipping costs and delivery times.

Used when you ship from multiple locations and want to automate picking the most cost-effective fulfillment point for each order.

Inventory management

Protect your strategic stock

Reserve safety stock by product, collection, or location. Avoid stockouts during demand spikes without manually blocking your inventory.

Used when you're launching a marketing campaign and want to guarantee in-store stock while continuing to sell online.

Ship from Store

Turn your stores into fulfillment hubs

Empower your retail teams to ship online orders without chaos. Set max daily capacity per store, balance workload across locations, and give your staff a seamless POS experience designed for in-store fulfillment.

Used when you want to leverage your store network to ship faster and cut delivery costs, without overwhelming your retail teams during peak hours.

"Charlie allowed us to roll out a new order routing strategy right before BFCM, with a level of speed and reliability we simply couldn’t have achieved otherwise."
