Software vendors are very good at demonstrations. They know their product intimately, they know which features impress and which ones to gloss over, and they have run this process hundreds of times. You have probably run it once or twice. The information asymmetry is significant, and most selection processes do not do enough to close it.
The result is that businesses end up buying systems that looked great in a conference room and turned out to be a poor fit for how they actually work. The implementation takes longer than expected, costs more than budgeted, and delivers less than was promised. The vendor moves on to the next deal. You are left managing the gap between what you bought and what you needed.
Here is how to run a selection process that changes that dynamic.
Start with the problem, not the product
The most common mistake in technology selection is starting with the market rather than the business. A leadership team hears that a competitor is using a particular platform, or reads that a certain category of software is transforming the industry, and kicks off a selection process before they have clearly defined what they are trying to solve.
Before you look at a single vendor, spend time getting precise about the problem. What is not working in the current system or process? What does good look like in twelve months? What are the constraints, budget, timeline, the capability of the team that will use and maintain the system?
The answers to these questions become your requirements. And the requirements are what the selection process should be testing against, not the feature set the vendor chooses to show you.
The questions that reveal real fit
A well-run demonstration follows the vendor's script. A well-run evaluation follows yours.
Build a set of scenarios based on how your business actually operates, including the edge cases, the exceptions and the workarounds that your team deals with every day. Ask the vendor to walk through those scenarios in the system, not their prepared slides. How the system handles the things that do not fit neatly is more revealing than how it handles the things that do.
A few questions that consistently surface useful information:
Show me how you handle [specific exception in your business]. Vendors prepare for the happy path. The way a system handles exceptions tells you a lot about whether it was designed for businesses like yours or for a more generic use case.
What does the implementation actually involve? Get specifics. How long does a typical implementation take for a business of your size? Who does the configuration work, the vendor or your team? What are the most common reasons implementations run over time or budget?
What does support look like after go-live? The sales team is attentive. Find out who you will be dealing with once the contract is signed and the implementation is complete.
Can we speak to three customers of similar size who have been live for at least twelve months? Not the references the vendor volunteers. Ask for the ones you want, and talk to them without the vendor in the room.
The reference check most people skip
The reference check is the most underused part of the selection process. Most businesses do it as a formality, asking broad questions and accepting broadly positive answers. Done properly, it is the most valuable source of information available.
Talk to people who have been through the implementation and are now running the system day to day. Ask them what they know now that they wish they had known before they signed. Ask what the hardest part of the implementation was and whether they would make the same decision again. Ask what they still find frustrating about the system. Ask whether the vendor's support has been responsive when something has gone wrong.
The answers you get from these conversations are qualitatively different from anything you will hear in a demonstration.
Red flags worth walking away from
A few things that should give you pause regardless of how good the demo looked.
Vague answers to specific questions. A vendor who cannot clearly explain how the system handles your specific requirements, or who redirects every detailed question back to a high-level capability, is either not confident in the answer or not willing to give it. Neither is a good sign.
An implementation timeline that seems too short. Underestimating implementation complexity is one of the most common ways technology projects go wrong. A vendor who is promising a very fast go-live for a complex system is either not being realistic or not asking you enough questions about your business to know what is actually involved.
Pressure to decide quickly. End-of-quarter pricing deals and expiring offers are sales tactics. A decision of this significance deserves the time it needs.
A contract that is hard to get out of. Long initial terms, automatic renewals, and punitive exit clauses shift risk from the vendor to you. Read the contract carefully, and if necessary have a lawyer look at it before you sign.
The question the whole industry would rather you did not ask
Here is something worth sitting with before you start any selection process.
Most businesses that buy a SaaS platform use a fraction of what they pay for. The vendor's feature count is a selling point. Your actual usage tells a different story. A handful of core workflows, a few reports, and a long list of capabilities that seemed important in the demo and have never been touched since. Meanwhile, the platform's assumptions about how work should be structured do not quite match how your business actually operates, so you spend time and money customising around the edges, or you change your processes to fit the software instead of the other way around.
This model is starting to look less inevitable than it once did.
AI has dramatically reduced the cost and time required to build software. A system that would have taken months to develop and a significant capital investment a few years ago can now be built in weeks, at a fraction of the cost, and built specifically for the way your business works rather than for a generic version of a business like yours. No unused features. No workarounds. No licence fees for capabilities you will never touch.
This is not relevant for every business or every system right now. The off-the-shelf platforms are mature, well-supported, and the right answer in many situations. But for businesses where the available platforms are a genuinely poor fit, where the customisation required is extensive, or where the ongoing licence cost is hard to justify against actual usage, a bespoke build is worth putting on the table as a real option rather than dismissing it as something only large enterprises can afford.
The honest question to ask at the start of any technology decision is not just "which platform should we buy?" It is "should we be buying a platform at all?"
The best technology decision is sometimes not to buy new software at all. Before committing to a replacement, it is worth asking honestly whether the problem is the system or the way it is being used. Underutilised systems that are poorly configured often look like systems that need to be replaced. Sometimes the better investment is getting more out of what you already have.
