Not sure why anyone would compare inoERP with SAP. SAP is big.100 times bigger than inoERP. Used by many large MNCs. On the other hand, inoERP is a small open source application used by mostly small startups.
It's not that inoERP is bad, but it should not be compared to SAP.
The only thing in inoERP that is better than SAP is the accounting processes. Accounting in SAP is a complete Joke. And, as inoERP is more like Oracle, the accounting process is way better, robust, and flexible compared to SAP. Everywhere else, SAP is 100 or even 1000 times better.
I can only speak to the UK, but I have found FreeAgent to be an amazing tool for running a limited company in the UK.
I have managed to integrate all of my bank accounts, Barclays, wise, capital on tap and have payments only auto explain, that and their API enables me to feed in Stripe invoices automatically and have them marry up with payments. Making day to day accounting easy.
I log in once a week and everything is just there. Once a month I press submit payroll and I am basically done, no need to pay for an expensive payroll service.
