Yes. There are multiple two way integrations that can be set up, for example to export invoice data with corresponding .pdf from GAT-Ship to ERP, or importing master data for customers and suppliers from ERP to GAT-Ship. Integrations are normally implemented as a separate sub-project with you, your ERP vendor and GAT-Ship, to make the best possible workflows. (From the technical side, such integrations will typically be implemented using our REST API (see https://api.gatship.com) or via .csv files.)
