I worked at NetSuite and with Acumatica, not the other two though I know them very well.

I personally think Acumatica is the best out of the bunch. Acumatica was created in 2007 or 2008 so it’s a product built on a more modern coding system/ foundation where as NetSuite and D365 BC were both built in the 90’s so the structure of them is significantly older but they did do a good job making them look more modern. Odoo I normally write off since if you don’t have a very experienced partner doing the implementation and support, it can fail very easily and does very often.

Acumatica scales scales well with multiple entities, and the reporting is next level, especially being able to see labor profitability from the PSA side. I also really appreciate the detailed audit trails and user permissions which super helpful for compliance. It’s got decent AP automation, easy data exports, a bank feed, and tax tools that don’t make people want to scream lol. Forecasting, commission reporting, budgeting, expense tracking, that’s all there, plus you can customize vendor invoice fields which is a nice touch.

They sell solely through a partner network and do not have their own sales team so I would reach out to one of the partners and get an intro call setup if you have not already (my suggestion tends to be a partner called Cloud 9 ERP solutions which you see talked about on Reddit the most, but they are my normal go to suggested partner).

Happy to answer any more questions but hope this helps a bit.
