Justin now I'm in the same soup

OneFlow does the job, but the cost is too high, especially for wholesale B2B. I think I'm gonna to develop my own system, something like this:
- Background Online Based App with Online Backup + Offline Backup with mockups on the image server + API to connect with Shopify, Amazon, eBay etc
- UPLOADING product print image on the server - choose products on which image can be printed, centering the image on the product (positioning) - Every product image (PNG) has own code/barcode created automatically by APP software.
- Software automatically produce mockup images, we only have to add descriptions and other data needed for shop
- Every unprinted product in our base will have own barcode connected with storage house.
ORDER from the WEB:
- When I get an order I will see what it consist off: Raw Product (barcode), Image to print on it (barcode), customer data etc
- Work Order File will be processed through own system which will create in the first step a ping to Storage Manager.
STORAGE:
- Storage manager will go to storage with a scanner and tablet and he knows what product he needs to pick (sublimation products for sublimation station, printing products for DTG station). He will scan the code on the storage spot and the stock of the product will automatically decrease.
- In the next step, he will print out an internal work order code and will label chosen products with it. Internat code will have all data needed for Production and Pack & Ship Station.
PRODUCTION STATION:
Production worker will scan that code previously labeled by storage manage, and he will automatically receive printing file to his machine PC or RIP with the process description, then he starts the process. Production worker doesn't know anything about customers, how many products are in that specific order etc.
PACK & SHIP STATION:
Packaging worker again scans the code and he sees what products (if there is more) he needs to include, what box or shipping bag to choose etc. He prints out shipping label, sticks it on the box and viola - done
Well, good luck Robert
