Ducotrax is an Inventory and warehouse management applicaiton that is integrated with Quickbooks Online. We've recently also created an integration for Shopify (Products and Orders) are pushed seamlessly into Ducotrax, and Orders are also pushed into QuickBooks for accounting - imagine not having to re-enter data for an order - EVER - fulfillment (pick-pack-ship) and accounting are updated automatically with the information created by the customer. Just think, no more data entry errors.
We are in need of some early adopters/evaluators so that we can finalize the functionality and polish the integration. We have a free 30 day trial, and if you contact us and are willing to be an early adopter we will sweeten the deal to make it worth your wild. Feedback and input are appreciated!
