ERP Review: How UK SMBs Should Evaluate Systems

An honest ERP review is one of the most valuable exercises a growing UK business can undertake. Whether you are questioning an ageing system or comparing a shortlist, a structured review tells you whether your finance software still fits the business, or is quietly holding it back.

Key PointA review is only as useful as the numbers behind it. Time the month-end, count the spreadsheets and list the workarounds before you score anything.

Why run an ERP review?

Most finance teams tolerate more friction than they realise. Manual re-keying, spreadsheets bridging gaps, reports that take days and month-ends that eat evenings all become normal over time.

An ERP review makes that friction visible and puts a cost against it. It also sets a baseline, so any change you make later is judged against real numbers rather than gut feel.

What to assess

Look across four areas, and give each one a score out of five for your current system:

• Functional fit: does the system handle core finance, VAT and reporting without workarounds?
• Usability: how much time does the team lose to clunky processes?
• Integration: does data flow cleanly between finance, sales and operations, or is it copied by hand?
• Cost of ownership: licences, support, hosting and the hidden cost of manual effort. Our Business Central cost guide shows how to put numbers on each line.

Check the support position of your current software too. Microsoft explains how product support ends in its lifecycle policy, and other vendors publish similar dates.

Score against real business needs

Resist the temptation to score on features alone. A long feature list means little if half of it goes unused.

Weight your criteria by what matters to your business, then score current and candidate systems the same way. For most UK SMBs the deciding factors are a fast month-end, reporting the leadership team trusts, and reliable VAT under HMRC's Making Tax Digital rules.

Pro TipScore your current system first, using the same weights you will use for the candidates. That stops a polished demo from quietly resetting the bar.

Watch for the warning signs

Certain symptoms surface in almost every review:

• unsupported or heavily customised legacy systems;
• growing reliance on spreadsheets to bridge gaps;
• difficulty consolidating several companies (see our multi-entity page);
• staff who fear the software rather than trust it.

Individually these are irritations. Together they signal a system that is now a brake on growth and a risk at audit time. Older, unpatched systems also carry a security cost, which the NCSC small organisations guide sets out clearly.

Watch OutIf a key process depends on one person and one spreadsheet, treat it as a risk, not a quirk, and write it into the review.

From review to decision

A good review ends with a clear recommendation and the evidence to back it. That might be to optimise what you have, or to move to a modern cloud platform such as Microsoft Dynamics 365 Business Central.

If you are weighing Business Central against Sage, our honest comparison for UK businesses covers the trade-offs. Microsoft's own Business Central documentation is the place to check any feature claim.

Either way, the review gives you a defensible business case rather than a hunch. That matters when you are asking the board to invest.

Making the review count

The value of an ERP review lies in acting on it. Turn the findings into a short, prioritised roadmap, give each item an owner and revisit it every quarter.

Done well, a review is not a one-off audit. It is the start of a habit of checking whether your systems still earn their place.
