Choosing an ERP is a decision a business lives with for years, so it rewards a clear process. The buying guide covers the overall framework. This article goes deeper on the part that decides the outcome: how to evaluate a system and the questions that reveal whether it fits.
Start with a requirements list, not a product
Before looking at any system, write down the functions that cause the most trouble today and the questions you cannot currently answer. Separate the must-haves from the nice-to-haves. This list keeps every conversation grounded in your business rather than in features you will never use, and it becomes the yardstick you measure each option against.
Questions about fit and size
-
Who is your typical customer, and how large are they? If the answer is far bigger than you, the system may carry complexity and cost you do not need.
-
Can we start with a few functions and add more later, without changing systems?
-
How does the system handle a business like ours as it grows?
Questions about the data and the modules
-
Do the modules share one database, so information is entered once and shared?
-
How does the system connect to the tools we plan to keep?
-
Is this one system, or several separate products under one brand?
Questions about security and data
You are trusting a provider with sensitive business data, so ask directly:
-
Where is our data hosted, and who can access it?
-
What protections and certifications are in place?
-
If we have data-protection obligations, how does the system support them, including where our data physically resides?
Questions about cost
Look past the headline price to the full cost over time: subscription, setup and configuration, data migration, training, and the cost of adding users or modules as you grow. A clear, modular price is easier to plan for than a single large quote.
Questions about implementation and support
Ask what a realistic rollout looks like for a business like yours, whether it can be phased, and what support you receive after go-live. A system that works out of the box, configured rather than rebuilt, is usually quicker and lower-risk.
How to run a demo that tells you something
A good demo is built around your scenario, not the vendor's script. Bring two or three real situations from your business and ask to see them handled end to end. Score each system against your requirements list in the same way, so you are comparing like with like rather than remembering the slickest presentation.
Check references before you commit
Ask to speak with a customer of a similar size and in a similar situation. A short conversation about how the rollout went, and what support has been like since, often tells you more than any feature list.
Key takeaways
-
Start from your own requirements, split into must-haves and nice-to-haves.
-
Ask about fit and size, one shared database, security and data residency, full cost, and a realistic phased rollout.
-
Run demos around your own scenarios and score every option the same way.
-
Speak to a reference customer of a similar size before you decide.
Frequently asked questions
How do I choose the right ERP for my business?
Start with a written requirements list, then evaluate each system on fit for your size, whether its modules share one database, its security and data handling, its full cost over time, and a realistic phased implementation. Run demos around your own scenarios and check a reference customer.
What questions should I ask an ERP vendor?
Ask who their typical customer is, whether you can start small and add modules, whether the modules share one database, where your data is hosted and how it is protected, the full cost including setup and growth, and what a phased rollout and ongoing support look like.
Should a growing business pick a modular ERP?
Usually yes. A modular system lets you begin with the functions that matter most and add the rest over time, which lowers both cost and risk compared with adopting everything at once.
Bring your own scenario. The best way to judge a system is to see it handle your real situations. Book a walkthrough of Dexter Plus and bring the processes that matter most to your business.
