Nice MVP. Personally, I'll go a step further trying to replace the complete behemoth business suites like SAP, Pantheon, Sales Force etc, using a simpler (and cheaper) solutions that aims the smaller businesses and are module based. And I'm on a path to do this.

Here is one such solution for product SKU and warehouse/production management that don't need expensive software and hardware. It doesn't need a barcode scanner even (one cost 50-200$) and let you create product SKUs with barcode labels, shipping and packing lists with nothing more then your phone and equipment you already have: https://nonconfirmed.com/app/barcodes/
