NetSuite Data Migration Done Right. The First Time.
EPIQ Infotech's structured migration methodology moves your records from any legacy system into NetSuite — clean, verified, and audit-ready — without disrupting your business operations.
The Risk Nobody Talks About
Most NetSuite Projects Don't Fail at Software Selection. They Fail at Data Migration.
Corrupted Historical Records
Misaligned field mapping creates phantom balances, duplicate vendors, and invoice mismatches your team then spend months manually fixing.
Go-Live Delays That Cascade
One skipped validation round can push your launch back by weeks. When operations are frozen mid-migration, the financial cost compounds daily.
Lost Business Continuity
Sales orders stuck in limbo. Vendor payments queued with wrong reference numbers. Poor migrations create customer-facing failures.
The 'Do-It-Twice' Tax
Companies that cut corners almost always pay twice — once for the original project, and again for specialists to fix what broke.
Audit & Compliance Exposure
Missing records and broken audit trails create genuine compliance risk, especially in regulated industries or pre-audit situations.
Wrong Partner, Compounded Risk
Many firms offer NetSuite implementation but treat data migration as secondary — handled by junior resources with generic tools.

Why EPIQ Infotech
A NetSuite Data Migration Partner Who Treats Your Data Like Their Own Business Depends on It.
EPIQ Infotech has delivered more than 100+ NetSuite migrations across manufacturing, distribution, professional services, retail, and SaaS. Every project runs through our structured Migration Framework — built from real-world lessons across a decade of NetSuite engagements.
Dedicated Migration Team
Your migration doesn't get handed to a generalist. EPIQ assigns a dedicated migration lead with specific NetSuite Suitescript and CSV Import expertise.
Pre-Migration Data Audit
We audit your source data before writing a single import template — surfacing duplicates, missing fields, and relational dependencies early.
Field Mapping as a Design Exercise
We map every field with business logic in mind — not just column names. You get data that works in context, not just data that landed in the right table.
Three-Phase Validation
Sandbox migration, hands-on guidance for reconciling against your source totals, and full UAT with your finance team before any go-live cutover..
Phased Migration
Your team continues operating in your existing system while we migrate and verify data in parallel — reducing downtime risk to near zero.
30-Day Post-Go-Live Support
Your migration consultant stays available for priority issue resolution, reconciliation queries, and corrective loads for a full month after launch.
Our Methodology
The EPIQ Migration Framework: Six Phases That Leave Nothing to Chance
Every successful NetSuite migration follows a defined sequence — and every shortcut within that sequence has a known consequence. Here's exactly how EPIQ Infotech runs a migration from first conversation to verified go-live.
Discovery & Source System Assessment
We map your current system's structure, identify which records carry active business value, determine what historical depth you need to retain, and surface any known data quality issues before the project timeline is set. This phase produces a Migration Scope Document.
Data Extraction & Cleansing at the Source
EPIQ provides guidance and support in preparing your source data — helping identify duplicates, standardize formats, and highlight referential integrity gaps, while your team owns the decisions on how records are resolved before transformation begins. Cleaning inside NetSuite after the fact is a backwards approach that risks embedding errors into live operations.
Field Mapping & Data Transformation
Every field in your source system needs a verified destination in NetSuite with the correct data type, format, and relationship to other records. We build detailed field mapping documents shared with your team for review and apply transformation logic for fields that don't translate directly.
Sandbox Migration & Reconciliation
Before anything touches your production environment, we run a full migration into the NetSuite sandbox. Automated reconciliation scripts compare record counts, financial totals, and relationship integrity against your source system. Finance team review follows. Discrepancies resolved here — not post-launch.
Production Migration & Go-Live Cutover
With sandbox validation complete, we execute the production migration during a planned maintenance window. For phased migrations, this happens in controlled waves — master data first, then open transactions, then historical records. Our team monitors in real time throughout the cutover window.
Post-Go-Live Support & Continuous Reconciliation
Migration doesn't end at go-live. EPIQ's 30-day post-launch support window covers edge cases, report anomalies, custom field adjustments, corrective data loads, and reconciliation support as your team settles into the new system. Your consultant remains on priority access.

Scope of Migration
Every Data Category Your Business Relies On — Migrated with Precision
A complete migration covers the full ecosystem of records that your operations depend on. Each category has its own complexity, sequencing requirements, and validation needs.
Customer & Contact Records
Full profiles including billing/shipping addresses, payment terms, credit limits, tax settings, and contact relationships — deduplicated and cross-referenced.
Vendor & Supplier Data
Vendor master records, purchase categories, payment terms, banking details, and associated contact history linked to correct subsidiary entities.
Inventory & Item Catalog
Product records include SKUs, pricing matrices, unit of measure, bin locations, serialized/lot-tracked items, and multi-location inventory balances.
Chart of Accounts & GL Balances
Account structure migration with opening balance verification, subsidiary mapping, department classification, and period-close balance validation.
Open Transactions
Open invoices, purchase orders, sales orders, credit memos, and payments in progress — migrated with correct aging, applied status, and linked document relationships.
Historical Transactional Data
Configurable historical depth — typically 2–3 years — covering closed invoices, completed POs, fulfillments, and receipts for reporting continuity and audit trail integrity.
Employee & HR Records
Employee profiles, department assignments, compensation data, expense reports, and timesheets for companies using NetSuite's HR and payroll modules.
Custom Fields & Business Data
Data captured in custom fields, notes, or non-standard entities in your legacy system gets mapped to custom record types or custom fields in your NetSuite instance.
Industry Experience
Migration Playbooks Built for Your Industry — Not a Generic Template
The way a wholesale distributor structures inventory data is fundamentally different from how a professional services firm tracks project billing. EPIQ maintains industry-specific migration playbooks that account for the data structures, compliance requirements, and operational workflows unique to each vertical.
Manufacturing
BOM, work orders, lot tracking, routing, production costing, and multi-site inventory.
Wholesale Distribution
Multi-location inventory, EDI data, 3PL records, and vendor managed inventory structures.
Retail & eCommerce
Product catalogs, order history, returns, gift card balances, and marketplace integration data.
Professional Services
Projects, billing rates, time entries, resource allocations, and milestone-based revenue records.
Life Sciences
Lot traceability, regulatory compliance records, GxP-relevant data structures, and clinical supply tracking.
SaaS & Technology
Subscription billing, ARR, deferred revenue, multi-year contract terms, and metered usage data.
Food & Beverage
Recipe management, batch costing, shelf-life tracking, and lot-controlled ingredient records.
Financial Services
Multi-entity consolidation, intercompany transactions, GAAP alignment, and regulatory reporting data.
Your industry isn't listed? Let's talk anyway. EPIQ has migrated data from nearly 30 different source systems across 15+ industries. The playbook might already exist.
How We Compare
Not All Migration Approaches Are Equal. Here's What the Difference Actually Looks Like.
Companies typically have three options when approaching NetSuite data migration: tackle it internally, hire a general NetSuite Support Services partner who bundles migration into implementation, or work with a specialist. The table below reflects what each approach actually delivers in practice.

Common Questions
Questions We Get Before Every NetSuite Data Migration Project
If you're evaluating NetSuite data migration options, these are the questions that come up in nearly every first conversation. Answered honestly below.
Q: How long does a NetSuite data migration typically take?
Timeline depends on your source system, data volume, and historical depth required. A QuickBooks Online migration for a 50-person company with 3 years of clean data can complete in 4–6 weeks. A multi-entity Sage 300 migration with 8+ years of transactional history and complex inventory can run 3–5 months with phased execution. The pre-migration audit we run at the start of every engagement gives you a realistic timeline before you commit to anything.
Q: How much historical data should we migrate into NetSuite?
The practical standard is 2–3 years of transactional history, which covers most operational reporting needs and keeps your NetSuite instance performant. However, this is a business decision. If your industry requires longer audit trials, if you're mid-fiscal year, or if you have open multi-year contracts, we may recommend migrating additional periods. We walk you through the trade-offs during the discovery phase.
Q: Can you migrate from QuickBooks to NetSuite?
Yes — QuickBooks (Desktop and Online) to NetSuite is one of our most frequently executed migration paths. The main challenges are structural differences in how QuickBooks handles the chart of accounts vs. NetSuite's subsidiary-aware GL, and the way QuickBooks stores customer/vendor relationships without relational rigor. Our QuickBooks migration playbook addresses both directly, including conversion of QB classes and locations into NetSuite's department, class, and location segmentation model.
Q: Will we need to shut down operations during the migration?
For most migrations, no. The data preparation, cleansing, field mapping, and sandbox migration phases all happen without touching your live systems. The only period where you need a maintenance window is the final production cutover — typically planned for a weekend. The cutover window itself is usually 24–48 hours depending on volume. For larger migrations, a phased approach allows your team to continue operating in the legacy system until final cutover.
Q: What if our source data is messy or incomplete?
This is the norm, not the exception. After 12+ years of NetSuite migrations, we've rarely encountered a source system with pristine data. The pre-migration audit specifically surfaces quality issues — duplicates, missing required fields, broken parent-child relationships, inconsistent formatting. We categorize each issue by severity and impact: some we resolve automatically, some require your team to make business decisions, and some may be candidates to simply not migrate. You'll know exactly what you have before any transformation work starts.
Q: Do you handle multi-entity or multi-subsidiary migrations?
Yes. Multi-entity migrations — consolidating data from multiple legal entities into a single NetSuite OneWorld instance — are among the more complex projects we handle. Each entity's chart of accounts, currency setup, tax configurations, and intercompany transaction history needs to be migrated and reconciled individually before the consolidated view is established. We've completed multi-entity migrations across 2–6 subsidiaries in a single project scope.
Q: How do you price a migration project?
Migration pricing is based on scope — number of record types, estimated record volume, source system complexity, and how much data cleansing is required. We provide fixed-fee project quotes after the initial discovery session. Fixed scope, fixed price, and defined deliverables mean no surprises mid-project and no hourly risk shifting onto your budget.
