  NetSuite Reimplementation Methodology: What LST Consultancy’s Approach Includes

  If your NetSuite system fails to deliver the expected results, a complete reimplementation may be the answer. However, most organizations overlook a critical factor: the approach you take during reimplementation is just as important as the decision to reimplement. The distinction between a successful reimplementation and an expensive failure typically depends on the methodology your implementation partner employs.

  At LST Consultancy, we helped 50+ companies successfully Reimplement NetSuite and transform their ERP systems. In this guide, we’re sharing the details of what a structured reimplementation methodology looks like – and how it enables your business to continue operations unabated (while propelling) with more advanced systems.

  Why Methodology Matters in NetSuite Reimplementation

  A structured methodology is not merely a choice – it is necessary. Organizations that collaborate with implementation partners who adhere to systematic processes will encounter:

  • Reliable timelines: You can plan to go-live and what it will be like

  • Fewer surprises: Problems reveal themselves in a controlled testing environment, not during mission-critical operations

  • Speed of adoption: Efficient change management gets the teams on board for the new system

  • Cost savings: If you fail to plan well, the risk of cost overruns from unstated requirements that can lead to scope creep and rework is high.

  Without structure, you have projects that waver, slip timelines, and break the bank, precisely what it looked like in those failed implementations to avoid.
  

  The 5 Core Phases of Our Reimplementation Approach

  Phase 1: Discovery & Assessment

  NetSuite Reimplementation success begins with knowing where you are today.

  We evaluate your existing NetSuite system in detail. What we look at is what they are using, what’s being customized, your data quality problem today, and where your team has pain.

  What happens during discovery:

  • Business Process Review: Map key processes and workflows for inefficiencies (order to cash, procure-to-pay, and financial close have the most critical impact)

  • Stakeholder Interviews: Ask users in finance, operations, sales, and IT what’s bothering them

  • System Audit: Review configuration, customization, and data to identify technical debt.

  • Gap Analysis: Comparison of business requirements vs what NetSuite has to offer

  • Risk Identification: Identify potential obstacles early for efficient decision-making.

  • Performance & Health Check: Review system speed, script performance, and integrations to identify bottlenecks that affect reliability and scalability.

  You will know where problems came from and what success looks like by the time you complete discovery.

  Phase 2: Planning and Design

  Let’s now sketch the very different path to your re-implementation.

  List timelines, roles, success metrics, and your future-state system architecture. This phase helps determine what must be constructed, what can be configured, and which legacy processes should be decommissioned.

  Key deliverables:

  • Project Charter: Scope, schedule, costs, and the organisational structure.

  • Process Design Document: What the processes will look like in the new system

  • Technical Architecture: Solution design, integrations, data flows, and a customized approach.

  • Change Management Plan: The approach of training and communication for adoption.

  • Data Migration Plan: How old data migrates from on-premises to NetSuite

  A little planning now can save weeks of delay later.

  Phase 3: Configuration & Build

  This is where your reimplemented system will be built.

  Our team sets up NetSuite based on design requirements, prioritizing the use of standard features and functionalities first. We set up your chart of accounts, security rules, financial structure, and automation using SuiteFlow. We resort to custom code only when the standard solution is inadequate for solving a business problem.

  This emphasis on configuration and modularity ensures that your system is maintainable and upgradable — no technical debt, which drove reimplementation.

  Activities during build:

  • Design a chart of accounts and financial structures

  • Configure core processes and workflows

  • Integrate the build system with your other tools

  • Custom scripts shall be coded only for high-value business processes

  • Prepare production environment

  During this phase, we maintain a sandbox so you can track progress, test functionality, and submit feedback before anything touches production.

  Phase 4: Testing & Data Migration

  Testing occurs throughout development but becomes more organized and methodical currently.

  We conduct multiple testing types: unit testing (does this work when you configure that?), integration testing (are systems communicating properly?), and user acceptance testing (does this fix your business problem?). We also do a lot of data migration work, cleaning up legacy data as it is migrated to NetSuite.

  We deliver end-to-end NetSuite testing and data migration to ensure reliable performance, seamless integrations, and clean legacy data transfer. Read More
