Script and Customization Refactoring
Rewriting SuiteScript that has become slow, duplicated or fragile, including scripts hitting governance limits or running in the wrong execution context.
NetSuite optimization services
Remediation work on a NetSuite account that has grown messy: slow pages, scripts fighting each other, workflows nobody remembers approving and reports that no longer reconcile.

Fixing the instance you already paid for
NetSuite accounts get slower and stranger over time, and it is rarely the platform. It is years of accumulated customization: scripts added by different people for different reasons, saved searches returning far more data than anyone needs, workflows layered over each other, and custom fields nobody can now explain.
Optimization is the remediation work that untangles that. We trace what is actually causing the slowness or the wrong numbers, then refactor scripts, rework saved searches, retire workflows that no longer serve a purpose and clean up the data structures underneath.
If you are not yet sure what is wrong, start with a NetSuite health check instead. That is the diagnostic: it tells you what the problems are and what fixing them involves. Optimization is the work that follows. Booking the diagnostic first usually costs less than commissioning remediation blind.

We start by reproducing the problem and tracing its cause rather than working from a symptom list, then agree a prioritized remediation scope with you. Work is built and tested in a sandbox against your real processes before it reaches production, and we tell you which items are genuine fixes and which are improvements you could reasonably defer.
What we optimize
From configuration to customization, every area is assessed against your actual operational needs.
Rewriting SuiteScript that has become slow, duplicated or fragile, including scripts hitting governance limits or running in the wrong execution context.
Reworking saved searches that pull more data than needed, return inconsistent results, or have quietly become the reason a dashboard takes a long time to load.
Reviewing SuiteFlow workflows to find overlaps, redundant approval steps and automations that fire when they should not, then consolidating them.
Addressing the record volume, duplicates and unused custom fields that accumulate over years of use and affect both performance and reporting accuracy.
Untangling role structures that have grown by exception, where permissions were added case by case until nobody can say what a given role can actually see or do.
Reshaping dashboards and forms around what each team actually needs day to day, which is often the difference between NetSuite being used properly and being worked around.
Our delivery approach
Technical quality is only part of a successful NetSuite engagement. The business requirement, release process and future responsibility also matter.
Clarify the process, users and expected outcome before selecting an approach.
Use standard NetSuite configuration when it meets the requirement properly.
Validate functionality, roles, exceptions and relevant downstream impact.
Document the change and agree who owns it after go-live.

Account-specific recommendations require an understanding of the actual business requirement and NetSuite environment.
A health check is the diagnostic. It reviews your instance and tells you what is wrong, how serious each issue is and what remediation would involve. Optimization is doing that remediation work. If you already know what needs fixing, go straight to optimization. If you only know that something is wrong, the health check is the cheaper starting point.
Usually accumulated customization rather than data volume alone. Common causes are scripts that run on every record save when they only need to run on specific conditions, saved searches returning very large result sets to a dashboard, workflows layered on top of each other over several years, and scripts approaching NetSuite's governance limits. Each was reasonable when added. The combined effect is what you feel.
Refactoring carries real risk, which is why the work is done in a sandbox first and tested against your actual processes before anything reaches production. Where a customization is load-bearing but badly built, we will say so and agree the approach with you rather than rewriting it unilaterally.
There is no universal interval. The practical triggers are a significant business change such as a new entity, module or acquisition, a noticeable drop in system responsiveness, or reports starting to disagree with each other. Reviewing after any of those is more useful than reviewing on a fixed calendar.
