I am a small business owner and I currently manage all accounting and inventory on Excel sheets. I would like to find an online service that is cost effective that will allow me to manage inventory in and out of my warehouse, as well as creating invoices, purchases and extracting PNL etc. For reference, the business is a engineering factory where we manufacture water/oil tankers, do maintenance for tanks, paint jobs for trucks etc. Currently, we dont need complex manufacturing management modules as our volume of work is quite small.

Its essential that the solution allows units of measure as I need this to track my inventory. It should also be scalable to support more modules and functionalities as the business grows (ie MRP). The only suitable thing I have found so far has been Odoo but it is expensive at about 195 USD/mo for all the initially needed functionalities and users (about 4-5 users). I have also checked Quickbooks Online and Xero and neither of these support Unit of Measure and seem to be quite inflexible so wont work from a scalability perspective...

Anyone know of solutions that are similar to Odoo, or good inventory management apps that work well with Xero or QBO to give me a full solution? Thanks in advance!
