A practical guide to evaluating ERP software for businesses of any size. What to look for, what to avoid, and how to run a proper selection process.
Most businesses don't buy ERP software once. They buy the wrong software, suffer through it for two or three years, then go through a painful migration to the right system. The average cost of a failed ERP implementation — in lost productivity, data migration, and staff time — is significant for any business.
Getting the selection right the first time saves money, saves time, and saves your operations team a lot of headaches.
This is the most important question, and the one most businesses ask last. Your ERP needs to handle:
If your ERP can't handle these natively, you'll end up with a patchwork of add-ons, workarounds, and manual processes. Ask vendors specifically: "How does your system handle [your country's] tax rules?" If the answer involves a third-party integration or a manual export, that's a red flag.
Many vendors claim their system is "all-in-one" when in fact it's several separate products connected by an integration layer. The difference matters:
Truly integrated: One database. When you make a sale, your stock, your accounts, and your CRM all update simultaneously. No syncing, no API calls, no lag.
Connected systems: Separate databases that exchange data on a schedule. Your stock system sends data to your accounting system every hour. Your accounting system sends data to your reporting tool every night. Errors accumulate at every junction.
Ask vendors: "Is this one database or multiple systems connected by an API?" The answer tells you everything.
ERP pricing is notoriously opaque. Common tricks to watch for:
Ask for total cost of ownership over 3 years, including all modules you need, all users you expect to have, and any implementation or training costs.
ERP problems happen at the worst possible times — end-of-month close, peak trading, payroll day. When something goes wrong, you need someone who picks up the phone.
Ask: "What is your SLA for critical issues? Can I speak to a human?" Check reviews on independent platforms. Look for comments about support response times, not just product features.
Step 1 (Week 1): Define your requirements. List every process you need the system to handle. Group them into must-have, should-have, and nice-to-have.
Step 2 (Week 2): Shortlist 3 vendors. Score each against your requirements list. Eliminate any that can't handle your compliance needs natively.
Step 3 (Week 3): Run demos. Give each vendor the same scenario: walk me through a full sales cycle, a payroll run, and a tax return for [your country].
Step 4 (Week 4): Trial the winner. Insist on a free trial with your own data, not a pre-loaded demo environment.
Step 5: Check references. Ask for three customers in your industry. Call them.
