Connect your ecommerce stores and marketplaces to Shiptheory and book shipments with GFS.
Shiptheory centralises your fulfilment workflow with automatic label creation, tracking, and manifest generation. If you use multiple carriers, Shiptheory keeps everything in one place while GFS manages carrier selection and delivery. Using Shiptheory with GFS removes manual work, speeds up dispatch, and gives you access to a wide network of domestic and international carriers through a single integration.

Connect your ecommerce stores and marketplaces to Shiptheory and ship internationally with confidence using GFS. Shiptheory automatically generates the customs documentation needed for every international order - commercial invoices, CN22s, and CN23s - removing the manual work and reducing the risk of delays at the border. Paired with GFS, you get access to a global carrier network with the compliance and paperwork handled automatically, so international orders move as smoothly as domestic ones.

Shiptheory and GFS work together to give retailers a smarter, more flexible shipping setup. With GFS providing access to a wide range of carriers and competitive rates, and Shiptheory automating labels and workflows, the combination means more delivery options at checkout, less manual work, and the carrier flexibility you need to grow across domestic and international markets.

Scaling your business means you need to choose the right carrier partners, give your customers more delivery options at checkout, reduce shipping costs through competitive rates, and build the flexibility to handle whatever peak season throws at you.
With Shiptheory and GFS, you can automatically select the required carrier and service based on a range of conditions, SKU, destination, weight and 1000's more.
