Mr. Hayk213
We have ready made libraries that can be used as a base for inventory and order tracking and management, stock tracking etc.
Also there is a full blown PICK-PACK-SHIP module ready that can be used on a tablet or an IPAD to scan bar code as well as tracking numbers.
Have integrated many shipping carrier's like UPS, USPS, FEDEX, royal mail, Yodel etc in the past.
We have also done integration for sales channels like amazon, ebay , walmart, shopify, Big commerce etc to name a few.
It would be good if we can connect and I can demo you a couple of software's that I have done for my clients. It will help the both of us understand what the needs are and then we can draft a solution proposal for you with cost and timeline estimates in sync to your business needs.
Awaiting your reply,
Regards_RR.
