Sage 100 to QuickBooks Conversion Services Compared

Short answer: Nobody converts Sage 100 to QuickBooks for free, because Intuit does not support the path at all. Intuit's conversion tool names Sage100 among the products it does not work with, and Dataswitcher, the partner Intuit pays for QuickBooks Online migrations, covers only Sage 50 US edition and Xero. That leaves three realistic options: hire a specialist conversion shop, do it yourself from spreadsheet exports, or split the job. Of the shops selling this service, only Numerawise publishes a price.

This is a buying guide, not a tutorial. Below is what each vendor actually commits to in writing, what they charge where they say so, how long they take, and where the published claims stop and the guesswork starts. Every figure here was read on the vendor's own page in August 2026 rather than lifted from a search result summary, because comparison articles in this niche repeat prices the vendors never published.

Why is there no free Sage 100 conversion?

Because Intuit built its funded migration path around the systems it competes with for small business customers, not mid market ERP. Intuit's help article on converting from Sage 50 to QuickBooks Desktop states that the conversion tool does not work with Peachtree, Sage 50 versions 2014 or older, Sage100, Sage 300, or the Sage industry specific products, and tells those users they can still move their data with Excel. Sage 100 is excluded by name.

The QuickBooks Online side is the same story with a different tool. Dataswitcher, which Intuit funds to move the last two fiscal years of data at no charge, supports Sage 50 US edition and Xero in the United States. Sage 100 is not on the list. So a Sage 50 shop gets two years moved for free and a Sage 100 shop next door gets nothing, which feels arbitrary until you notice it tracks which importers Dataswitcher has actually built.

What does Numerawise charge for a Sage 100 conversion?

Numerawise publishes a fixed price range of $2,000 to $6,000 on its dedicated Sage 100 page, and says it returns a fixed price quote within one business day of reviewing your setup. Its general conversion page frames the same work differently, putting mid market files with inventory or payroll history in a $2,000 to $5,000 band, against $500 for a small single entity file and $5,000 to $15,000 for NetSuite, Sage Intacct and multi entity conversions.

Its published scope covers the chart of accounts with segmented account mapping, customers and vendors with open AR and AP, inventory items with quantities and valuation, payroll year to date figures, and historical transactions with the scope agreed before work starts. It states a ten point validation reconciling all balances to the source system and thirty days of post go live support at no extra charge. It also states plainly that custom reports built in Crystal Reports do not transfer.

What do Dancing Numbers and MMC Convert charge?

Neither publishes a price for Sage 100. Dancing Numbers sells the conversion and routes you to a quote request, with general timeline claims of 24 to 72 hours for automated conversions and three to seven days for manual work, averaging 72 hours. None of that is specific to Sage 100, and Sage 100 is not an automated conversion for anyone, so treat those figures as marketing for the easy cases rather than a commitment on yours.

MMC Convert also quotes on request, but it does describe its process concretely: you complete a migration order form, MMC gives an ETA, and completion is expected within three to five working days, ending with a quality analysis report and a comparative trial balance matching each ledger between the source system and QuickBooks Online. Post migration support runs seven days at no extra cost. That trial balance deliverable is the right thing to ask every vendor for, whoever you pick.

What should I check before handing over my file?

Ask how the vendor takes possession of your data. At least one provider in this market asks for login credentials on the order form rather than a file upload, and handing an ERP login to a third party is a different decision from sending an export, particularly if your Sage 100 file contains payroll records. If your business is under any kind of audit or compliance obligation, that difference is worth raising internally before you sign.

Then ask three scoping questions in writing. How many years of transaction history are included at the quoted price. What happens to inventory if the file is on LIFO or standard cost. And what the remediation is if the trial balance does not tie out at the end. Vendors who answer those crisply are the ones who have done Sage 100 before rather than treating it as a generic Sage job.

Is it cheaper to do a Sage 100 conversion myself?

Sometimes, and the dividing line is fairly clear. A single entity file, two or three years of history, no inventory or simple FIFO inventory, and payroll already handled by an outside provider is genuinely a do it yourself job. You export from Sage 100, rebuild the chart of accounts, load lists, enter opening balances at a closed period end, and bring transaction history in as converted files.

Multi entity structures, LIFO or standard cost inventory, in house payroll history, or a heavily customized ERP push it the other way fast. In those cases the $2,000 to $6,000 is buying a validation process and someone who has hit the same walls before, and the real comparison is not fee against zero, it is fee against your controller's month.

What does the do it yourself route actually involve?

Sage 100 exports through two mechanisms. Business Insights Explorer handles ad hoc views: open a view, choose File then Export Options, and pick from Microsoft Excel, Access, Word, a Microsoft Query Definition file, XML, comma or tab delimited text, or HTML. Be aware the Query Definition option exports no data at all, only the DSN and the SQL behind the view. For bulk work, Visual Integrator defines reusable export jobs that push any Sage 100 table to an ODBC database or an ASCII delimited file, with schedulable runs.

Getting the data out is the easy half. The destination is where it binds. QuickBooks Online accepts a CSV of three columns of date, description and amount, or four columns of date, description, credit and debit, English only, at 350 KB and 1,000 transactions per upload. QuickBooks Desktop cannot import a bank CSV in any version at all. Converting your exports to .qbo files sidesteps both problems and gives you Bank Feeds review instead of a raw paste. The Sage 100 to QuickBooks conversion guide walks the full sequence, and the converter at the top of this page handles the file itself.

What costs do not appear in any quote?

Three, and they are the ones that blow up budgets. The first is the parallel period, when you are paying for Sage 100 and QuickBooks at the same time while you prove the new file. Sage 100 subscriptions are priced per named user per month and billed annually according to ERP advisory sites, so a two month overlap on a ten user file is real money. Do not shorten the overlap to save it.

The second is reporting. Crystal Reports customizations do not transfer, so whatever management reporting the business reads each month has to be rebuilt on the other side. Budget time for that specifically, and scope it to the reports the business genuinely reads each month rather than recreating the full Crystal Reports library. The third is the restatement if your inventory sits on LIFO or standard cost, since QuickBooks Desktop values inventory at weighted average and QuickBooks Online uses FIFO on Plus and Advanced only. That one has tax consequences and belongs with your CPA, not your bookkeeper.

How do I know the conversion actually worked?

The test is a trial balance comparison as of the cutover date, run in both systems, matched line for line. Every reputable vendor offers some version of this, whether they call it a ten point validation or a comparative trial balance report. If you are doing the work yourself, do the same thing, and do it before you enter a single transaction that only exists in the new file.

When it does not tie, three patterns explain most breaks. A difference that divides evenly by nine is transposed digits. A difference exactly twice the value of a transaction is a sign flip, which happens constantly on credit card accounts because the sign convention reverses. A difference matching one transaction exactly is a row that either failed to convert or got accepted twice. Running automated account reconciliation across the first few closed periods catches the third category early, while both systems are still open and the answer is cheap to find.

Which route should I pick?

Start by pricing the work honestly against your own capacity. If your file has inventory on anything other than FIFO, in house payroll history, or more than one entity, get quotes from at least two shops and insist on the trial balance deliverable in the contract. Numerawise is the one that will give you a number without a call, which makes it the useful anchor even if you end up elsewhere.

If your file is a single entity with clean books, doing it yourself is a reasonable month of work and you keep the knowledge in house, which matters more than it sounds when someone asks in March why an account looks the way it does. Either way the transaction history moves the same way, through converted files rather than an Intuit tool, because Intuit does not offer one for Sage 100. For the destination mechanics see CSV to QuickBooks Online, and if you are weighing other systems the Sage Intacct to QuickBooks migration guide and the NetSuite to QuickBooks migration guide cover the two other ERPs Intuit leaves out.
