If you manage a portfolio of QuickBooks Desktop clients, you have probably already heard about Jet Convert. It is free. Xero promotes it. It has processed a large volume of conversions over more than a decade. So the natural question is: why would an accounting firm pay for a QuickBooks to Xero migration when a free option exists?
The honest answer is that not every file is the same. For a single-currency client with one or two fiscal years of history and a clean chart of accounts, Jet Convert handles the work well. For a manufacturing client running USD receivables on a Canadian books-of-account file with eleven years of transaction history, the same tool produces results that your team will spend days reconciling.
This article compares Jet Convert and WOW BookSwitch on the dimensions that matter when professional liability is on the line: pricing model, validation depth, multi-currency handling, historical data coverage, and the workflow fit for firms managing fifty to two hundred and fifty client files at once.
What Each Service Actually Is
Jet Convert
Jet Convert is Xero's official conversion partner. The service is subsidised by Xero, which means the standard tier carries no fee for the firm or the end client. It handles the current fiscal year plus one prior year in the free tier, with extended history available as a paid add-on. The conversion runs through automated processes with quality assurance steps before delivery.
WOW BookSwitch
WOW BookSwitch is a professional QuickBooks Desktop to Xero migration service operated by WOWzer Technologies Inc. The base package is $399 USD per conversion and covers the current fiscal year plus three prior years. Each additional year is $100 USD. Firms converting thirty or more files receive a 15% volume discount automatically. Turnaround is one to three business days. Every converted file goes through AI post-conversion validation followed by trained accountant review and correcting entries before delivery, and six months of WOW Backup and Restore is included.
The two services sit in different positions on the market map. Jet Convert is the free, high-volume option. WOW BookSwitch is the paid, validated option built for firms that cannot afford an undetected error.
Pricing: What You Actually Pay
Jet Convert is free for the standard tier. The cost on the invoice is zero. The cost is not zero on your team's time if the conversion contains errors that need to be found and fixed manually.
WOW BookSwitch is $399 USD per conversion, dropping to roughly $339 with the 15% volume discount at thirty or more files. A portfolio of one hundred files runs about $33,915 with the discount applied.
The comparison is not really about the sticker. It is about what the firm pays in staff hours after delivery. A converted file that requires twelve to seventeen hours of manual reconciliation, at a $200 per hour billing rate, has cost the firm $2,400 to $3,400 in opportunity cost regardless of what the conversion service charged.
Validation: The Real Differentiator
This is where the two services diverge most clearly.
Jet Convert runs automated conversion with quality assurance. There is no AI validation layer that compares the converted Xero output against the QuickBooks Desktop source across trial balance, balance sheet, and profit and loss. There is no trained accountant review applying correcting entries before delivery. If the converted file has a discrepancy, your firm finds it.
WOW BookSwitch's validation is the core of what the $399 buys. Every file is compared against the source across all three reports. Discrepancies flag automatically. A trained accountant, not a general support agent, reviews each flag and applies correcting entries before delivery. You receive a clean file and a written validation report you can file with the client record as your audit trail.
The 95% accuracy guarantee backs this up. If the converted file does not meet that threshold across the three reports, the fee is refunded in full.
Multi-Currency: Where Free Tools Fail
WOWzer's Q4 2025 direct testing confirmed what many firms have already encountered: free third-party conversion tools, including Jet Convert, do not handle multi-currency files reliably. The structural limitation is not a bug that will get patched. It is a function of how the tools were designed.
For a Canadian firm with clients running USD-denominated transactions, GBP supplier accounts, or EUR receivables, this matters. A Jet Convert conversion on a multi-currency file may produce a balance sheet that does not match the source, with FX variances that take days to trace.
WOW BookSwitch handles multi-currency conversions with full foreign exchange preservation across all years in scope. The AI validation runs year by year, period by period, on every currency. Correcting entries reconcile any variance before the file ships.
If your portfolio includes import/export clients or professional services firms with US-dollar invoicing, the multi-currency capability gap is the single most important factor in the choice.
Historical Data Coverage
Jet Convert's standard tier covers the current fiscal year plus one prior year. Extended history is available at additional cost, and the practical reliability of extended-history conversions through free tools degrades as the year count climbs.
WOW BookSwitch covers four years in the base package. Each additional year is $100. For a client with ten years of required history, that is $399 plus six additional years at $100 each, or $999 total, and the AI validation runs across every year, not just the most recent ones.
For Canadian firms, this matters more than it sounds. The CRA requires six years of records under Section 230 of the Income Tax Act, and the parallel GST/HST retention obligation runs alongside it. The QBD source file remains the system of record for retention purposes. Migrating to Xero does not change the archival obligation.
Workflow Fit for Firms Managing Portfolios
A managing partner with 187 client files on QuickBooks Desktop is not making a single conversion decision. They are making a portfolio decision. Batch processing capacity, dashboard visibility into in-flight conversions, predictable turnaround times, and the ability to phase delivery without taking on review bottlenecks all become operational concerns.
Jet Convert is built around individual conversions. There is no batch portal for firm-level submission, no phased portfolio delivery schedule, no dedicated firm contact.
WOW BookSwitch's platform supports concurrent batch processing with a firm-level migration dashboard. Files upload through a single interface. Turnaround stays at one to three business days even at volume. Firms running thirty or more files get a dedicated account contact and the option to phase delivery to match their internal review capacity.
For a firm migrating a hundred clients between now and the September 2027 QuickBooks Desktop 2024 end-of-support date, the operational difference compounds.
When Each Option Is the Right Call
Jet Convert is the right choice when the file is genuinely simple. Single currency. One to two years of history. A clean chart of accounts. No complex class tracking. The client is comfortable with a longer manual verification step on your end.
WOW BookSwitch is the right choice when professional liability is the deciding factor. Multi-currency exposure. Extended history requirements. Portfolio scale where staff time on reconciliation would dominate the project budget. Client relationships where an undetected error would be more expensive than the conversion fee on every file in the portfolio.
Most accounting firm portfolios contain both kinds of files. The decision is rarely Jet Convert or WOW BookSwitch for every client. It is more often Jet Convert for the simple files and WOW BookSwitch for the complex ones, with the actual split depending on the client mix.
What Does Not Transfer Through Either Service
A few items do not migrate through any QuickBooks Desktop to Xero conversion, professional or otherwise: bank feeds, payroll history, attachments, and memorised transactions. GIFI code mapping is coming soon to WOW BookSwitch but is not currently live. These items require post-migration setup in Xero regardless of which service performs the conversion. Being clear about this up front prevents the awkward conversation with the client three weeks after go-live.
A Practical Way to Decide
A firm reviewing the choice does not need to pick one service for the whole portfolio. The practical approach is to segment the client base into three tiers: simple single-currency files with limited history, standard files with moderate complexity, and complex files with multi-currency or extended history requirements. Each tier routes to the conversion path that fits.
The simple tier can move through Jet Convert. The standard and complex tiers are where the WOW BookSwitch validation layer pays for itself in staff time saved and professional liability protection earned.

Frequently Asked Questions
1. Can I transfer QuickBooks data to Xero?
Yes. A QuickBooks Desktop to Xero migration moves the chart of accounts, transactions, customers, vendors, and historical data into Xero. Bank feeds, payroll history, attachments, and memorised transactions do not transfer through any conversion service and need to be set up fresh in Xero after migration.
2. Why would my firm pay for WOW BookSwitch if Jet Convert is free?
The free price tag covers automated conversion without AI validation or trained accountant review. WOW BookSwitch's $399 USD per conversion includes both, plus correcting entries applied before delivery and a written validation report. For multi-currency files, files with extended history, or any file where an undetected error would be costly, the validation layer is what the fee buys.
3. How does the QuickBooks to Xero migration handle multi-currency transactions?
WOW BookSwitch handles multi-currency conversions with full foreign exchange preservation across all years in scope. WOWzer's Q4 2025 testing confirmed that free conversion tools, including Jet Convert, fail on multi-currency files. The structural limitation is not a bug. It reflects how those tools were designed.
4. What does the WOW BookSwitch 95% accuracy guarantee actually cover?
The converted Xero file is compared against the QuickBooks Desktop source across trial balance, balance sheet, and profit and loss. If the output does not match the source to a 95% accuracy threshold across those three reports, the conversion fee is refunded in full.
5. How long does a QuickBooks to Xero conversion take with WOW BookSwitch?
Most conversions complete within one to three business days, including the AI validation and accountant review steps. Turnaround stays consistent even for firms submitting files in batches of thirty or more.
6. Does Xero offer a desktop version like QuickBooks Desktop?
No. Xero is a cloud-native accounting platform with no desktop equivalent. The QuickBooks Desktop to Xero migration moves your file from local hosting to cloud-based access, which is part of why the migration is necessary as Intuit phases out QuickBooks Desktop support.
7. Can Xero import QuickBooks data without using a conversion service?
Xero provides a Conversion Toolbox that accepts CSV exports from QuickBooks Desktop. It handles simple single-currency files with limited history but typically requires twelve to seventeen hours of manual staff time per file to format, import, and reconcile. For portfolios of any meaningful size, the manual approach is not practical.
8. What happens to my QuickBooks Desktop file after the migration?
The QBD source file stays in your archive. For Canadian firms, the CRA six-year retention obligation under Section 230 of the Income Tax Act applies to the source records regardless of how much history migrates to Xero. The conversion does not replace the retention obligation.
9. Is the conversion data routed through Canadian infrastructure for Canadian firms?
Yes. WOW BookSwitch routes Canadian client conversions through AWS Canada infrastructure. US client conversions route through AWS US. Data does not cross jurisdictional boundaries during conversion.
10. What happens if we find a problem in the converted file after delivery?
WOW BookSwitch's accuracy guarantee covers the 95% threshold across trial balance, balance sheet, and profit and loss. If the converted file does not meet the threshold, the fee is refunded. The six months of WOW Backup and Restore included with every conversion also protects against errors that surface in the first post-migration reporting cycle, with daily backups of your Xero organisation from the go-live date.
