Accounting CS vs QuickBooks Online for CPA Firms: Pricing, Bank Data and Client Write-Up

For a CPA firm that keeps books for dozens of small clients, Accounting CS is usually the better home for write-up clients: one Thomson Reuters system holds every client file, the trial balance, payroll and the financial statements, and it is priced to the firm by quote rather than per client company. QuickBooks Online wins for clients who run their business in the software every day, but each company carries its own $38 to $340 monthly subscription. Neither one reads a PDF bank statement, and moving a client from Accounting CS to QuickBooks Online is harder than moving one the other way.

Accounting CS vs QuickBooks Online at a glance

The two products answer different questions. Accounting CS asks how a firm should produce accurate books and statements for many clients. QuickBooks Online asks how a business owner should run their own finances, and then lets the accountant in. Most of the differences below follow from that.

How much does Accounting CS cost compared with QuickBooks Online?

Thomson Reuters does not publish a price for Accounting CS. The product page offers a contact sales form and a phone number, and hosting providers that resell CS Professional Suite describe the quote as depending on the modules and user count a firm licenses. So the only honest comparison is structural: Accounting CS is a firm cost that does not grow with every new write-up client, and QuickBooks Online is a per-company cost that does.

QuickBooks Online list prices after Intuit's August 1, 2026 increase are $38 a month for Simple Start, $85 for Essentials, $140 for Plus and $340 for Advanced, per company. On the accountant side, Intuit is replacing QuickBooks Online Accountant with Intuit Accountant Suite through the second half of 2026: the Core plan is free, Accelerate is $149 a month from July 1, 2026, and the Books Close add-on is $8 per client per month for up to 50 clients or $6 per client beyond that.

The middle row is why so many firms end up running both. Clients who already pay for QuickBooks cost the firm nothing to access. Clients who never want to log in to anything are the ones where a per-company subscription becomes the firm's overhead, and that is the group Accounting CS is built around.

Where client bank data comes from in each

Bank activity is most of the data entry in write-up, so the import paths matter more than any feature list. Both products have a feed, both accept files, and both stop at a PDF.

One detail catches firms new to Accounting CS. Lines imported on the Bank Statement Import tab take the posting period end date, because that tab exists to match statement lines against transactions already in the books. When the books are empty and the client sent PDFs, the transactions have to be created, which means Spreadsheet Import, which keeps each row's own date and can mark the rows cleared for the reconciliation. The step by step mapping, including the Transaction Type column the wizard requires, is on our Accounting CS bank statement converter page. For QuickBooks clients the same PDF becomes a CSV or QBO file, covered on the QuickBooks bank statement converter page.

Can Accounting CS import from QuickBooks Online?

Yes. From File > Import > QuickBooks Online you sign in to the client's company, choose the data types and a date range, and map the items. Thomson Reuters lists transactions, the chart of accounts, vendors and bank accounts as importable, and says Intuit does not currently offer a way to bring over payroll information or classes. Every QuickBooks item has to be mapped to an Accounting CS item before the import runs, and the mapping is saved for later imports.

That makes Accounting CS a reasonable place to consolidate a client who has outgrown doing their own books in QuickBooks and now wants the firm to take over. Payroll history is the piece to plan for separately.

Can you move a client from Accounting CS to QuickBooks Online?

Not through an export. Accounting CS sends client data to QuickBooks Desktop Pro, Premier and Enterprise only, and Thomson Reuters states that QuickBooks Online is not supported as a destination. There is a second restriction that surprises people: only transactions entered or modified in Accounting CS can be exported, so rows that arrived through a spreadsheet import cannot go out that way at all.

In practice a client leaving for QuickBooks Online starts with opening balances and a fresh bank history, which is where the original statements matter again. If the firm kept the converted statement files in the workpapers, the bank history can be rebuilt in QuickBooks from those files instead of from the PDFs. It is a small habit that turns a painful offboarding into an afternoon.

Which clients belong in which system

There is also a reporting angle. Accounting CS produces the financial statements itself, which is a large part of why firms pay for it. A firm that keeps some clients in QuickBooks and still wants presentation-ready reports for a lender or a board can turn the bookkeeping export into GAAP-style financial statements without rebuilding them by hand in Excel.

The bank statement step is the same in both

Whichever ledger a client lands in, the slowest part of write-up is still the stack of PDF statements from accounts that will not connect or from months the feed cannot reach. Converting them is one workflow with two outputs: an .XLSX workbook for Accounting CS Spreadsheet Import, or a CSV (and a QBO file on the Plus plan) for QuickBooks Online. BankXLSX Starter is $49 a month, or $24 a month billed yearly, and Plus is $149 a month, or $74 billed yearly, with bulk upload of up to 50 files. Both include unlimited users, and a new account gets a one-time 15 page demo with no credit card.

Firms that also have tax clients in Drake will find the same decision laid out in Drake Accounting vs QuickBooks for tax preparers, and the audit and tax file workflow for larger practices is on bank statement CSV for CPAs. For a January rush where every client sends twelve months at once, batch bank statement conversion handles the whole year in one pass.
