Converting Quicken Home & Business or Premier Data to QuickBooks Desktop
Quicken converts to QuickBooks Desktop only partially: categories, loans, and investments need careful handling before the books balance at cutover.
The built-in converter in QuickBooks Desktop moves a Quicken file across in one pass, but the pass is narrow. It was designed to carry banking history, not the full personal-plus-business picture that Quicken accumulates. This playbook covers the whole run: preparing the file, knowing what converts, remapping the chart, handling loans and investments, and proving the balance before you cut over.
Prepare the Quicken file before you convert
Work from a copy of the data file, never the live one. Conversion builds a new company file and is not meant to alter Quicken data, but a dated copy removes all risk.
Check version support early. The converter runs in QuickBooks Desktop for Windows only, and it accepts a narrow window of recent Quicken for Windows releases. If your file is several years old, upgrade it in Quicken first, then convert the upgraded copy. Data that starts in the Mac edition of Quicken must be moved to the Windows edition before any of this applies.
Pick a hard cutover date, ideally a month end. Reconcile every bank and credit card account in Quicken to that date, and accept or delete every pending downloaded transaction. Unreconciled items convert as ordinary transactions, and you lose the record of which ones you had already accepted.
What moves across, and what gets dropped?
The converter brings over the registers: checking, savings, and credit card accounts with their history. Categories become income and expense accounts, classes become classes, and payees become names. From Home & Business, customer and vendor lists come across, and open invoices and bills land in receivables and payables.
Investment accounts and their security-level history do not convert. Budgets, memorized reports, and online banking connections stay behind. A loan arrives as a plain liability account with a balance, because its amortization schedule does not survive the trip. None of this is a defect: the two programs model these things differently, and the converter translates only where a direct equivalent exists.
Map Quicken categories to a real chart of accounts
Expect a flat, noisy account list. Quicken categories were built for personal reporting, so a list assembled over years mixes genuine business expense with household spending.
Clean it in three passes. Merge duplicates and near-duplicates first, which the converter creates whenever a category was renamed over the years. Group what remains under parent accounts and apply your numbering. Then reclassify the categories that were never income or expense. Loan principal, transfers between your own accounts, and owner draws belong in liability and equity accounts, not on the profit and loss statement.
Decide the mapping on paper before you touch the converted file; we keep a two-column worksheet, Quicken category on the left, QuickBooks account on the right. If the target chart needs rebuilding rather than tidying, treat chart-of-accounts design as its own exercise and finish it before the worksheet, not after.
Loans and investment accounts need a separate plan
Loans arrive as balances without terms. Confirm the liability balance against the Quicken loan schedule, then rebuild the remaining amortization: term, rate, and payment amount. The built-in Loan Manager can hold those terms and write the payment split for you, but check its first payment against Quicken's amortization table before trusting the series.
Investments need manual entry. Create one account per brokerage or fund, dated at cutover, with a single opening balance taken from the statement. Decide up front that Desktop will track the account's value and not individual lots or securities, since there is no securities register. Keep cost-basis records wherever they live now; the converted file will not hold them.
Prove the trial balance before cutover
Assemble the source numbers first: a net worth report from Quicken, and an income and expense report by category, both dated at cutover. Run the balance sheet and profit and loss in the converted file for the same date, then compare line by line. Every difference should have a name: an investment account that did not convert, a category you remapped, a loan you restated.
Post one journal entry to true up the balance sheet, with the plug going to opening balance equity. Then move opening balance equity into retained earnings or owner's equity so the sheet reads cleanly.
Run the Verify utility, and treat a clean pass as necessary but not sufficient. Verify checks a set of structural rules and does not inspect transaction chains, so chaining damage can sit in a file that passes. A converted file is a rebuilt file, and it deserves the deeper check before you rely on it or merge anything into it. If totals refuse to tie, or Verify reports errors, treat that as QuickBooks Verify and Rebuild repair work rather than a bookkeeping problem.
The last proof is operational: reconcile the first bank statement after cutover and confirm a zero difference.
Rollback points and a clean outcome
Three points protect you. The untouched Quicken copy is the first: discard the new company file and start again at no cost. The second is a .QBB backup taken right after conversion, before any remapping; return to it if the chart cleanup goes sideways. The third is a .QBB taken before the opening-balance journal entry, the last unadjusted state of the file.
A clean outcome looks like this: the balance sheet ties to the Quicken net worth report to the dollar, every category sits where you put it, loan payments amortize correctly, investments reconcile to their statements, and the file verifies with no chaining faults behind the pass. At that point you can cut over and retire the Quicken file to read-only archive duty.
