Tallmont QuickBooks to NetSuite Migration Services
For: Businesses leaving QuickBooks — single file or twenty — that want the move done once, correctly, with numbers that reconcile.
Moving to NetSuite is easy. Moving correctly is the job.
Anyone can export QuickBooks lists and import them into NetSuite — there are tools for it. What the tools can’t do is the accounting: decide the subsidiary structure, redesign a chart of accounts that stopped fitting the business years ago, untangle the intercompany balances that never matched, and prove — with reconciled trial balances — that the new system starts from the truth.
That’s the difference between a data migration and an accounting migration. We do the second kind.
What our migration includes
Structure designed before anything moves. Entity hierarchy, unified chart of accounts, segments and dimensions — the decisions that determine every report you’ll ever run. We design them with you first, so NetSuite reflects the business you have now, not the QuickBooks file you’re escaping. (Full detail on our implementation approach →)
Data cleanup as part of the move. Miscoded history, unreconciled accounts, duplicate customers and vendors, stale open items — fixed before cutover, not imported as-is. A migration is the cheapest moment you’ll ever have to clean your books.
Reconciled cutover — the non-negotiable. Trial balances compared entity by entity, QuickBooks vs NetSuite, before and after. You sign off on the tie-out. Your comparatives to prior periods survive the move.
Multi-file consolidation. Multiple QuickBooks files become one NetSuite instance with real subsidiaries, intercompany automation, and push-button consolidation — the exact engagement in our 20-entity migration case study.
Your team, self-sufficient. Training, role-based dashboards, and hands-on support through the first several month-end closes. We leave when the new normal is boring — or stay on as your monthly accounting team.
When to migrate (and when not to)
NetSuite earns its cost when QuickBooks starts costing more than it charges: spreadsheet consolidations, entities that don’t reconcile, inventory or project accounting held together with add-ons, lenders asking for statements you can’t produce quickly. We wrote the full self-diagnosis here: 7 signs it’s time to switch.
And sometimes the honest answer is don’t migrate yet — a QuickBooks cleanup buys another year or two at a fraction of the cost. The free books review tells you which side of that line you’re on; we’ll give it to you straight either way.

How long does a QuickBooks to NetSuite migration take?
A single-entity migration typically runs 8–12 weeks end to end. Multi-entity consolidations — merging several QuickBooks files into one NetSuite instance — run 3–5 months depending on entity count and how much cleanup the data needs first. We give you a fixed scope after the free review.
How much historical data should we bring into NetSuite?
Our default: opening balances plus open transactions (unpaid invoices/bills), with 1–2 years of monthly trial-balance history for comparatives. Migrating every historical transaction is usually cost without benefit — QuickBooks stays available read-only as the archive. We'll advise based on your audit and reporting needs.
Can you merge multiple QuickBooks files into one NetSuite account?
Yes — it's our specialty. We've consolidated 20+ separate QBO files into a single NetSuite instance with a unified chart of accounts, subsidiary structure mirroring the legal entities, and intercompany balances verified at cutover.
Will our numbers match after the migration?
That's the defining test. We reconcile trial balances entity by entity — QuickBooks vs NetSuite — both before and after cutover, and you sign off on the comparison. No go-live until they tie.
What does a migration cost?
Fixed-fee, scoped after the free books review — driven by entity count, data quality, and how much structural redesign the chart of accounts needs. You'll know the number before we start; there is no hourly meter.
