Quick Summary
QuickBooks conversion is one of the most consequential projects a growing business will undertake — and one of the most commonly underestimated. Moving from QuickBooks Desktop to QuickBooks Online, or from either platform to Intuit Enterprise Suite, isn't a file transfer. It's a data audit, a chart of accounts review, an integration reconfiguration, and a workflow redesign — all of which determine whether your books are clean and accurate on the other side, or whether you're six months into the new platform fixing errors that were baked in at go-live. Certum Solutions manages QuickBooks conversions from start to finish, with a fixed scope & a team that's been doing this since 2005.
The Bigger Picture
What "QuickBooks Conversion" Actually Means
QuickBooks conversion refers to the process of moving your company file, historical data, chart of accounts, vendor and customer records, and open balances from one QuickBooks platform to another — or from QuickBooks to a different accounting system entirely. It includes data migration, cleanup of legacy errors, chart of accounts restructuring, integration setup, and team training in the new environment.

What We Do
QuickBooks Conversion Paths We Handle
QuickBooks Desktop → Intuit Enterprise Suite (IES)
For businesses outgrowing Desktop's user limits, inventory constraints, or multi-entity limitations, IES is the natural next step — cloud-native, Intuit-familiar, and significantly more capable than either Desktop or QBO. Certum is a certified IES implementation partner and has completed this migration path more than any other in our practice.
QuickBooks Desktop → QuickBooks Online
The most common conversion we handle. Certum audits your Desktop file before migration begins, resolves data quality issues, restructures the chart of accounts for the QBO environment, migrates historical data with year-over-year reporting continuity, and configures the integrations your business needs before go-live. Most Desktop-to-Online conversions take 3–6 weeks depending on file complexity.
QuickBooks Desktop → Odoo ERP
For manufacturers, distributors, and businesses with operational complexity that QuickBooks can't model — multi-warehouse inventory, bill of materials, production orders, multi-department costing — Odoo ERP handles accounting and operations in a single platform. Certum is a certified Odoo Ready Partner and manages the full conversion including operational data migration, not just financial records.
QuickBooks Online → Intuit Enterprise Suite
For businesses that moved to QBO and have now hit its ceiling — typically around the time multi-entity reporting, advanced inventory, or user capacity become issues — IES provides the next tier of capability within the Intuit ecosystem without requiring a platform change to Odoo or another ERP.
QuickBooks Desktop → Zoho Books
For businesses consolidating into the Zoho ecosystem — CRM, inventory, accounting, and HR under a single platform — Certum migrates QuickBooks financial data into Zoho Books including chart of accounts mapping, vendor and customer record import, historical transaction migration, and first-month-end close verification.
QuickBooks Desktop → Xero
For businesses that prefer Xero's interface or are moving into an industry where Xero has stronger ecosystem support — construction in some markets, service businesses, e-commerce operations using Xero-native integrations — Certum handles the full conversion including historical data preservation, chart of accounts rebuild, and Xero integration configuration.
Other Accounting Software → QuickBooks
Certum also handles conversions from Sage, Peachtree, Dynamics GP, FreshBooks, Wave, and other legacy systems into QuickBooks Online, QuickBooks Enterprise, or IES. If you're moving from a platform not listed here, contact us — we've likely done it.
