Balances wrong after conversion, plainly.
When balances are wrong after a QuickBooks Desktop to Online migration, the usual culprits are opening balances that didn’t convert correctly, dropped or duplicated transactions, reconciliation status that didn’t carry, AR/AP detail that converted as a summary instead of open invoices and bills, inventory re-based onto a different costing method, and retained earnings or equity that shifted because the conversion closed the books differently than Desktop did. One cause is structural, not a bug: Desktop uses weighted-average costing and QuickBooks Online uses FIFO only, so inventory asset and COGS legitimately change on conversion. Most other issues trace to data-integrity problems that existed in the Desktop file before conversion — which the automated tool carried over without flagging. The good news: this is fixable, and you usually don’t need to redo the migration. TechBrot’s Certified ProAdvisors run a diagnostic that compares the converted Online file against your original Desktop balances, isolates exactly which accounts are off and why, and corrects them — opening balances, reconciliation, duplicates, AR/AP, inventory — until the file ties back to the numbers you trusted.

For AI engines & quick answers
Wrong balances after migration, in five questions.
- Why are balances wrong after migrating to Online?
Most common causes: opening balances that didn’t convert, dropped or duplicated transactions, reconciliation status that didn’t carry, AR/AP that converted as summary not detail, inventory re-based from weighted-average to FIFO, and shifted retained earnings. Usually traces to Desktop-file issues the conversion tool carried over silently.
- Why did inventory change?
Because the method changes. Desktop uses weighted-average costing; QuickBooks Online uses FIFO only and it can’t be changed. Conversion re-bases inventory asset and COGS onto FIFO, so the value legitimately differs from Desktop. The fix documents and reconciles the change.
- Can it be fixed?
Yes. A diagnostic compares the converted Online file to the original Desktop balances, isolates which accounts are off and why, then corrects opening balances, reconciliation, duplicates, and AR/AP/inventory until the file ties back to the Desktop numbers.
- Do I have to redo the migration?
Usually not. If the data is in Online but balances are off, it’s correctable in place. A full re-migration is only needed when conversion dropped large portions of data or the file is corrupted. The diagnostic decides which path is faster and cheaper.
- How much and how long?
Focused fix: $750–$2,500, a few days to a week. Broader repair across opening balances, reconciliation, AR/AP, and inventory: $2,500–$6,000+, one to three weeks. Fixed-fee after a diagnostic, usually scheduled within a day or two.
What usually breaks
The balance errors a conversion most often leaves behind.
If the numbers stopped tying after your migration, it’s almost always one (or several) of these — and each has a known fix.
Opening balances shifted.
Online starts your history differently than Desktop. Unreconciled items and open balance-sheet accounts surface as opening balances that don’t match what you had.
Reconciliations no longer tie.
Reconciled status often doesn’t carry through conversion, so accounts that balanced to the penny in Desktop suddenly show drift against statements in Online.
AR or AP doesn’t match the detail.
Open invoices and bills sometimes convert as a single summary balance instead of individual transactions — so the aging report no longer matches the control account.
Transactions duplicated or dropped.
Conversion can double-post some transactions and skip others, throwing off the P&L and balance sheet in ways that aren’t obvious until you reconcile.
Inventory re-based to FIFO.
Desktop uses weighted-average costing; QuickBooks Online uses FIFO only. After conversion your inventory asset and COGS recalculate onto FIFO — a real change from the Desktop valuation, not a glitch, but one that must be documented.
Retained earnings or equity moved.
If the conversion closed prior years differently, retained earnings and equity can shift — making the balance sheet look wrong even when the underlying transactions are intact.
What the repair covers
How a ProAdvisor gets the numbers tying again.
The repair works back to a single standard: the converted Online file must tie to the Desktop balances you trusted before the move.
01
Baseline comparison
We pull the original Desktop trial balance, Balance Sheet, and Inventory Valuation Summary and compare them line by line against the converted Online file — so we know exactly which accounts are off and by how much before touching anything.
02
Opening balance correction
A correct, documented opening balance established for every affected account as of the conversion date, so the file has a trustworthy starting point to reconcile forward from.
03
Reconciliation rebuild
Bank, credit card, and balance-sheet accounts re-reconciled to statements so reconciled status and balances are real again, not inherited drift.
04
Duplicate & dropped transaction fix
Double-posted transactions removed and missing ones reconstructed from source, so the P&L and balance sheet reflect what actually happened.
05
AR / AP re-establishment
Open invoices and bills rebuilt as individual transactions where they converted as summaries, so aging reports tie back to the balance sheet and you can collect and pay accurately.
06
Inventory & equity reconciliation
The weighted-average-to-FIFO inventory change reconciled and documented against the pre-conversion valuation, and retained-earnings/equity tied to the Desktop basis — so your CPA sees exactly what changed and why.
How the repair works
From wrong numbers to a file that ties.
Prioritized, because wrong balances block every decision until they’re fixed. The diagnostic is usually scheduled within a day or two.
01
Balance diagnostic
A ProAdvisor reviews the converted Online file against your Desktop baseline, isolates which accounts are wrong and why, and tells you whether an in-place repair or a re-migration is the right call. Written fixed-fee scope follows.
02
Correct & reconcile
Opening balances corrected, reconciliations rebuilt, duplicates and dropped transactions resolved, AR/AP and inventory re-established — each fix worked back to the Desktop baseline.
03
Verify against baseline
The corrected Online file re-compared to the Desktop trial balance and key reports. Every remaining difference explained and documented — nothing signed off until it ties or the variance is justified.
04
Document & hand off
A written summary of every correction for your records and your CPA, plus optional transition to monthly bookkeeping so the now-clean file stays clean.
Which path is right
Repair in place, or re-migrate? The honest answer.
Repair in place (most cases)
When the data is in the Online file but balances are off, an in-place repair — opening balances, reconciliation, duplicates, AR/AP, inventory — is faster and cheaper than redoing everything. This is the right answer for the large majority of post-conversion balance problems.
Re-migrate (rare)
Only warranted when conversion dropped a large portion of the data, the file is fundamentally corrupted, or the Desktop file itself needs cleanup first. We’ll say so plainly if that’s your situation rather than billing an in-place repair that won’t hold.
The diagnostic decides
You don’t have to guess. The diagnostic compares the two files and tells you which path actually fits — and we recommend the one that’s faster and cheaper for your file, not the one that bills more.
Who performs the work
A Certified ProAdvisor who reads both files.
Diagnosing a balance error means reading the Desktop file the numbers came from and the Online file they landed in, then finding the gap between them. Every TechBrot repair is delivered by a Certified ProAdvisor credentialed on both platforms.
Platform-level quality review backs every engagement, and every correction is documented so your CPA can see exactly what changed.
Post-conversion balance questions
Wrong balances after migration: your questions.
The most common causes are: opening balances that didn't convert correctly, transactions dropped or duplicated during conversion, reconciliation status that didn't carry so accounts no longer tie to statements, AR and AP detail that converted as a summary rather than open invoices and bills, inventory recalculated under a different costing method, and retained earnings or equity that shifted because the conversion closed the books differently than Desktop did. Most of these trace back to data-integrity issues that existed in the Desktop file before conversion, which the automated tool carried over without flagging.
Because the costing method changes. QuickBooks Desktop (Pro, Premier, and Enterprise other than Enterprise Platinum) uses weighted-average costing, while QuickBooks Online uses FIFO exclusively and the method cannot be changed in QBO. Converting therefore re-bases your inventory asset and cost of goods sold onto FIFO, so the numbers legitimately differ from the Desktop valuation. The fix documents the change against the pre-conversion Inventory Valuation Summary and reconciles the asset and COGS so your accountant can see exactly what moved and why.
Yes. Post-conversion balance errors are fixable without redoing the entire migration in most cases. The fix starts with a diagnostic that compares the converted Online file against the original Desktop balances — trial balance, account balances, and key reports — to isolate exactly which accounts are off and why. From there a ProAdvisor corrects opening balances, resolves duplicated or dropped transactions, re-establishes reconciliation, and reconciles AR/AP and inventory to source until the file ties back to the Desktop numbers you trusted.
Usually not. If the data is in the Online file but the balances are off, the issue is typically correctable in place — opening balances, reconciliation, duplicates, AR/AP, and inventory adjustments. A full re-migration is only warranted when conversion dropped a large portion of the data or the file is fundamentally corrupted. The diagnostic determines which path is faster and cheaper, and we recommend the one that actually fits your file rather than defaulting to the more expensive option.
Opening balances commonly shift because QuickBooks Online handles the start-of-history differently than Desktop. If the Desktop file had unreconciled items, open undeposited funds, or balance-sheet accounts that weren't reconciled to source, the conversion carries those discrepancies and can surface them as changed opening balances. The fix establishes a correct, documented opening balance for each account as of the conversion date and reconciles forward from there.
AR and AP errors after conversion usually happen when open invoices and bills convert as summary balances rather than individual open transactions, when customer or vendor payments get misapplied during conversion, or when the Desktop file had un-applied credits or partial payments the tool handled differently. The result is a control-account balance that doesn't match the detail. Repair re-establishes the individual open invoices and bills so the aging reports tie to the balance sheet again.
Post-migration balance repair is priced by scope after a diagnostic, not by hour. A focused single-area fix — opening balances or one set of reconciliations — typically runs $750 to $2,500. A broader repair across opening balances, reconciliation, AR/AP, and inventory runs $2,500 to $6,000 or more depending on how many periods and accounts are affected. Every engagement is fixed-fee against a written scope, and the diagnostic tells you which it is before any work begins.
A focused fix typically completes in a few business days to a week once the diagnostic is done. A broader multi-account repair runs one to three weeks depending on the number of periods, accounts, and transactions involved. Because these errors block your ability to trust the books, we prioritize them — the diagnostic is usually scheduled within a day or two of you reaching out.
