NetSuite

True cloud based subscription ERP solution, have not had to hire any IT staff, robust business intelligence, highly configurable to meet business needs, always on the latest version at no additional cost, extensive partner network, easy to expand as business grows, multi-company, multi-currency, good CRM capabilities and very reasonable price for what you get (less than cost of one good IT person).

Not crazy about NetSuite support cost/value. They offer good support, but their costs are much higher than their partners. We shifted our support to their partner network for scripting and reporting needs after a few years. Also, their pricing can be a bit of a challenge, but is reasonable. They eventually want to get everyone to pay their retail subscription price, however, they deeply discount it initially as many companies can't take advantage of or use all that is available to them in their base ERP offering and the more functionality you commit to the deeper the discount, however, they reduce the discount each year to eventually get to retail. Kind of makes sense, because as you expand your use of their software they eventually want you to pay for the full use, but will start out with deep discounts.

Might be biased, since I'm a developer, but the ability to customize the software's functionality and create entirely new modules with a widely used programming language as javascript is really good and something we have taken advantage of, like a lot. Documentation has its flaws but is helpful most times. The learning curve is a bit steep, but nothing that can't be overcome.

I hate the reporting functionality, avoid it if I can. Might be that I don't really understand its uses. I'd rather do saved searches.
Some changes are made that are not included in release notes or in between releases that affect how our customizations work.
Also, too many unexpected error messages and error messages that misrepresent the actual problem. These force us to google for answers.

They sold it really well and their sales team was very enthusiastic and engaging.

It is absolutely a nightmare to implement. It is way too complicated to function well. You need to be a developer to be able to do even the most basic augmentations. You might as well just build your own system from the ground up and save yourself the expensive NetSuite bill. The cost is huge and you can't make adjustments to licenses without long contracts. Despite their claims they don't know anything about integrating with other systems like Shopify via connectors like Celigo or FarApp. The integration team will not help you avoid even common pitfalls. The user interface is, despite their claims, woefully not intuitive or easy to use for average computer savvy individuals. You cannot easily make or adjust print or email templates and their WYSIWYG editor is garbage. The shipping component of it is far less powerful and customizable than many other shipping softwares like ShipStation. Their manufacturing processes are not customizable enough and don't account for realistic manufacturing challenges. You will absolutely end up doing way more steps for not much gain, making it very inefficient to operate. Their "support" is very limited and after you are past your support phase, help is non-existent unless your entire system is down. They are not appropriate at all for small to medium size businesses (despite their claims) and should only be used if you have an entire IT team that could probably just code a custom system for you anyway. Absolutely would not recommend!
