12 Common ERP Implementation Mistakes (and How to Avoid Them)
The ERP implementation mistakes we see most often — from recreating the old system to skipping data rehearsals — with practical ways to avoid each.

Overview
An ERP audit gives you an independent, evidence-based view. We examine configuration, data, custom code, integrations, security and how the system is governed, and we deliver findings ranked by business impact with practical recommendations.
01The problem
Inventory valuation, receivables or margins that finance cannot trust.
Users maintain parallel spreadsheets because they do not believe the system.
Months after go-live, the same issues keep recurring.
No independent way to assess whether the current partner's work is sound.
02Our approach
We review the system from several angles at once: configuration against business processes, data quality through profiling, custom code through review, integrations through logs and error history, and security through roles and access. We interview key users to understand where trust has broken down.
Findings are written plainly and ranked by impact: what is costing money or risk now, what will cause problems as you grow, and what is cosmetic. Each finding comes with a recommendation and a rough effort estimate.
03Capabilities
Costing, accounting, warehouse, approval and workflow settings checked against how the business operates.
Duplicates, missing values, inconsistent units and orphaned records quantified.
Custom modules assessed for quality, security, performance and upgrade risk.
Error rates, retry behaviour, data ownership and monitoring examined.
Roles, segregation of duties, inactive users and credential handling.
Change control, documentation, support model and ownership.
04Technical considerations
Audits are performed with read-only access to a copy of production where possible.
Sub-ledgers compared to the general ledger to locate valuation and posting issues.
Automated scanning of custom code combined with manual review of critical paths.
Error and job logs analysed for recurring failures and their frequency.
05Process
Agree areas, access and stakeholders.
Reviews, profiling, interviews and testing.
Prioritised findings with recommendations and effort estimates.
Findings presented to leadership with a recommended action plan.
06Outcomes
A precise list of what is wrong and why, backed by evidence.
Effort directed to the issues that matter most.
An objective assessment you can share with partners and leadership.

Who you need on an ERP implementation team: sponsor, project lead, key users, data owner, consultants and developers, with realistic time commitments.
Why ERP adoption fails and how to fix it: role-based training, key users, floor-level sessions, quick reference guides, and measuring adoption after go-live.
FAQ
Typically two to four weeks, depending on system size, number of integrations and access to stakeholders.
We report what we find, factually and fairly. The aim is to fix problems, not assign blame.
Read-only access to a copy of production is usually enough. We will specify what is needed during scoping.
