Most businesses don’t wake up one day and decide their ERP is broken. A report that used to take five minutes now takes twenty, a workaround becomes “just how we do things,” and nobody remembers the last time someone actually looked under the hood. Below is a closer look at each of the ten signs, why they happen, and what they usually mean for the business behind the scenes. 

1. Reports take longer than they should

If your finance team is exporting to Excel to “fix” numbers before a meeting, NetSuite isn’t doing its job. Report lag is rarely about the platform itself, it’s almost always a symptom of saved searches that have grown unwieldy over time, dashboards built for a business that looked different two years ago, or underlying data volumes that have outpaced how the system was originally configured. The fix is often smaller than people expect, but it only gets found by someone actually looking. 

2. You’re maintaining shadow spreadsheets

Parallel spreadsheets usually mean the system isn’t trusted or isn’t configured to give people what they need. Once a spreadsheet becomes the “real” source of truth for a process, it tends to stay that way indefinitely, because nobody has the time to go back and rebuild trust in the system itself. The longer this continues, the more risk it introduces: spreadsheets don’t have the same audit trail, access controls, or version history that NetSuite does. 

3. Month-end keeps slipping

A clean close shouldn’t feel like a fire drill every single month. When a close routinely runs late, it’s usually because of manual reconciliation steps that should be automated, unresolved data discrepancies that get chased down after the fact instead of prevented, or approval workflows that create unnecessary bottlenecks. None of these are permanent conditions — they’re configuration issues that tend to get more entrenched the longer they go unaddressed. 

4. Nobody’s touched your workflows in years

Your business has changed. Has your NetSuite instance changed with it? Workflows built for a five-person finance team rarely still fit once that team has doubled, added new entities, or expanded into new markets. Left alone, workflows just become quietly inefficient, adding small amounts of friction to hundreds of transactions a month. 

5. Customisations nobody remembers building

Old scripts and custom fields pile up quietly until nobody’s sure what’s safe to remove or why it’s there in the first place. This is one of the most common findings in a health check: instances with dozens of custom fields that no process actually uses anymore, scripts built for a workflow that was since replaced, or SuiteApps installed years ago and never revisited. Beyond the clutter, unused customisations can also slow performance and complicate future upgrades. 

6. Support tickets keep circling the same issues

Recurring problems are usually a symptom of something structural, not a string of bad luck. If your team keeps opening tickets for the same category of issue like a sync that breaks, a report that errors out, an approval that stalls that’s a pattern worth investigating at the root.

7. New hires struggle to get up to speed

If onboarding someone into NetSuite takes weeks of “just ask around,” the system has drifted from best practice. A well-configured instance, with clear workflows and sensible naming conventions, should be reasonably intuitive for a new finance or operations hire. When onboarding depends entirely on tribal knowledge, that’s a strong signal the system has accumulated undocumented complexity. 

8. Integrations feel fragile

If a sync breaking causes genuine panic, your integration layer probably needs attention. Integrations that were built quickly to solve an immediate problem often lack proper error handling, logging, or fallback processes which is fine until the day something breaks during a busy period and nobody can tell what data is missing or duplicated. 

9. You’ve grown, but your ERP hasn’t

More entities, more transactions, more complexity and the same setup from three years ago. Growth is exactly the kind of change that should trigger a periodic review of ERP configuration, because what worked at one scale often creates friction at the next. Multi-entity consolidation, intercompany transactions, and higher transaction volumes all stress-test a configuration in ways the original setup was never designed for. 

10. You genuinely don’t know how healthy your instance is 

This is the biggest one. Most teams have never had someone independently review performance, data integrity, and configuration against best practice. It’s easy to normalise the day-to-day friction of a system you use constantly until someone with an outside perspective points out what’s actually fixable. Not knowing is, in itself, a risk. 

What a health check actually involves 

A proper NetSuite health check typically reviews system performance and page load times, data integrity across key modules, unused or conflicting customisations, integration stability, user access and permissions, and reporting accuracy. The output isn’t a vague list of concerns — it’s a prioritised set of findings, with a clear view of what’s quick to fix, what needs planning, and what’s actually working well and doesn’t need to be touched. 

Frequently Asked Questions 

How do I know if my NetSuite instance needs a health check? 

Common signs include slow reporting, reliance on shadow spreadsheets, month-end closes that keep slipping, outdated workflows, unexplained customisations, recurring support tickets, slow onboarding for new staff, and fragile integrations. 

What is a NetSuite health check? 

A NetSuite health check is an independent review of an instance’s performance, data integrity, and configuration against best practice, identifying what’s working, what’s costing time, and what’s fixable in the short and long term. 

Does a health check mean I need to rebuild my NetSuite instance? 

No. Most health checks result in targeted fixes rather than a full rebuild. The assessment identifies priority issues so businesses can address them incrementally. 

What causes ERP performance to decline over time? 

Performance typically declines as businesses grow without updating their configuration — accumulating unused customisations, outdated workflows, and integrations that were never revisited as transaction volume and complexity increased. 

Why do finance teams keep using spreadsheets alongside NetSuite? 

Parallel spreadsheets usually indicate the ERP isn’t fully trusted or isn’t configured to deliver the reporting a team needs, prompting staff to rebuild numbers manually outside the system. 

How much does a NetSuite health check cost? 

Foresee Solutions offers a free, no-obligation ERP Health Check to assess instance performance and identify improvement areas before any commitment is required.
