Linnworks - reintegration project

We are a shoe business selling on Amazon, eBay and Magento with over 14k sku's however, only Amazon and eBay is live on Linnworks and Linnworks is only being used for ordering processing and not it's full capabilities which is stock and inventory management. We require help in re-integrating this and potentially starting again.

We require the following:
- Help/advice on best set up
- Implementation
- Testing
- Launch

Are you able to help?

Thanks,
