How long does an ERP evaluation typically take?

This varies enormously by organisation size and how many stakeholders need to sign off — there's no universal number worth citing here. What matters more than speed is whether the evaluation actually tested the specific workflow your pain is centered on, not just watched a generic demo.

Should we build a custom system instead of buying ERP software?

That's a real, legitimate option for a narrow, well-understood process — but it means owning ongoing maintenance, security patching, and feature development yourself indefinitely. Most organisations find that cost compounds faster than expected once the process needs to change.

Is a free or open-source ERP a safe first step?

It can be, for organisations with in-house engineering capacity to self-host, patch, and extend it. The real cost to evaluate honestly is total cost of ownership over several years, not just license price — hosting, customization, and support all have to come from somewhere.

The ERP Buying Guide

Key takeaways

Start from your most acute, quantifiable operational pain — not a feature checklist copied from a competitor's site.
Data migration and integration scope are the two most commonly underestimated parts of an ERP decision.
A phased, module-by-module rollout reduces change-management risk more than a full-system cutover.
Ask every vendor for a real screenshot or live demo of the specific workflow you care about — not a slide deck.

Start from your real operational pain, not a feature list

The most common ERP evaluation mistake is starting from a generic feature checklist — every vendor will check most of the boxes on a generic list, which tells you nothing about fit. Start instead from the specific, quantifiable pain your organisation actually has: a month-end close that takes two weeks because nobody trusts the numbers until they're reconciled by hand, a stockout that happened because nobody had real-time visibility into on-hand inventory, a quotation that took a week to get approved because it lived in an email thread.

Write that pain down in concrete terms before you take a single vendor call. It becomes the filter every subsequent decision runs through — including which modules to implement first.

Which modules should you implement first?

Most organisations get the fastest real value by implementing the module that owns their most acute pain first, not by attempting a full-system rollout simultaneously. A distributor with stockout problems often starts with inventory and procurement; a services firm with margin visibility problems often starts with projects and accounting; a manufacturer drowning in spreadsheet BOMs often starts with manufacturing and stock together, since the two are structurally connected.

A phased rollout also reduces change-management risk in a way that's easy to underestimate going in: a team learning one new governed process at a time adapts faster than a team facing a full-system cutover on day one, and each phase's real usage data informs configuration decisions for the next phase.

Data migration and integration are the two most underestimated costs

Almost every ERP evaluation focuses heavily on feature comparison and under-invests in scoping data migration and integration — and these are consistently where real implementation timelines slip. Ask concretely: what happens to your existing customer, item, and supplier records? Who reconciles migrated data against the source system before go-live, and how? What existing tools (e-commerce, payment gateways, shipping carriers) need a real integration, not a manual export/import workaround?

See the ERP Implementation Checklist and ERP Migration Guide for the specific, sequenced questions to ask on this — it's dense enough to deserve its own dedicated treatment rather than a summary here.

Questions worth asking any vendor — including Vercentlabs

Ask for a real screenshot or live walkthrough of the specific workflow you care about, not a generic product tour. Ask what happens when two departments' data disagrees — is there a real audit trail, or does whoever edited last silently win? Ask how role-based access actually works: can access be scoped to a specific branch or time-bound to a contractor's engagement, or is it all-or-nothing? Ask what's explicitly not yet automated — a vendor that can name a real, current limitation is more trustworthy than one that claims full automation everywhere.
