How to choose between two software vendors fairly
A straight method for comparing two software vendors on the work you actually do, the costs neither quote mentions, and when to stop evaluating and decide.
Both demos went well and that is the problem
You have sat through two presentations. Both products did everything asked of them. Both salespeople were likeable and both quotes are within range of each other. You now have no basis for a decision and the natural response is to ask for more demos, which produces more of the same confidence and no more information.
Demos are rehearsed on clean data by someone who uses the product daily. They are designed to show capability rather than friction. The decision you are actually making is which product your least enthusiastic employee will use correctly on a busy Tuesday with messy data. Nothing in a demo tests that and almost nothing in a feature list predicts it.
The costs neither quote includes
Implementation is excluded from the licence price almost everywhere. So is data migration from your current system, which is usually the largest line in the real total and is often quoted only after you have committed. Training is separate. Integration with your accounting system is separate and sometimes requires a higher tier. Support beyond email may be a paid add-on. GST at 18% applies on service fees in India and software billed in US dollars moves with the exchange rate.
Then there is the cost of your own time. A proper evaluation of two products takes a few days spread over a fortnight and someone senior has to spend it. Price the renewal too. Ask what the increase was last year for existing customers rather than what the list price is today, because year one pricing on a new contract tells you very little about year three.
When to run an evaluation and when to just pick one
Run a structured evaluation when the system will hold data you cannot easily move, when more than a handful of people will use it daily, or when the annual cost is material against your overheads. Those three conditions make a wrong choice expensive and slow to reverse.
Do not run one for a small monthly tool that one person will use and that stores nothing irreplaceable. A week of deliberation costs more than a year of the wrong subscription and you can switch in an afternoon. Do not run one if you have already decided and are collecting justification, because it wastes everyone's time and produces a document nobody believes. And do not run an evaluation to settle an internal argument about whether the business needs this software at all. That is a different question and vendor selection will not answer it.
How to compare them honestly
Write down what you need before you see anything further. Five must-have requirements expressed as tasks rather than features. Not reporting module but produce the monthly stock reconciliation our accountant accepts. Anything beyond five is a wish and will dilute the scoring. Agree the list with the people who will use the system rather than with the people who will sign for it.
Then run the same test on both. Take your own data, imperfect as it is, and perform your three most frequent real tasks in a trial account. Time them. Have the actual user do it rather than you. Ask both vendors the same written questions and compare the written answers, since verbal assurances evaporate at implementation. Find one reference customer yourself rather than accepting the one offered. And before signing, export your data out of the trial and look at what you get.
How to judge the decision afterwards
The metric that matters is adoption at ninety days. What proportion of the intended users are in the system weekly and is the old spreadsheet still running alongside it. A parallel spreadsheet is the clearest possible signal that the chosen product does not fit the work.
The metric that flatters is feature coverage. A scorecard showing one vendor matching forty-one requirements against thirty-eight feels decisive and measures almost nothing, because most of those features will never be switched on. Weight the three tasks your team repeats hundreds of times a month far above everything else and let the rest be tie-breakers.
The common mistake
Letting the vendor set the evaluation criteria. It happens quietly. A salesperson sends a helpful comparison grid, you adopt its categories, and the grid was built around where that product is strong. Every subsequent conversation then runs on their terms. By the time you notice, the losing vendor is being judged on capabilities nobody in your business will ever use.
The expensive version is choosing on price and discovering the migration cost afterwards. A lower annual licence with a migration that doubles once your real record count is known is not the cheaper option, and by then you have announced the decision internally and will defend it rather than revisit it. Scope migration against a sample of your real data before the contract.
Settle the exit before the entry
Ask both vendors in writing how you get your data out, in what format, how long it takes and what it costs. Ask what happens to your data if you stop paying and for how long it is retained. A vendor who answers plainly is telling you something useful about how they expect to keep your business. A vendor who treats the question as unusual has answered it too.
