How Accounting Firms Are Saving 1 Hour Per Client This Tax Season

Tax season is a numbers game — and not just the kind your clients pay you to run. There's another set of numbers every CPA firm quietly manages: the hours lost to manual data work that has nothing to do with actual tax expertise.

For firms that use QuickBooks Online to manage client books and Thomson Reuters UltraTax CS to prepare returns, there's a gap in the middle. A gap that, for most firms, gets filled with manual re-entry — opening QBO, exporting a trial balance, opening UltraTax CS, and typing those numbers in by hand.

The average cost of that gap? Approximately one hour per client.

This post explains why that hour keeps disappearing, what it's costing your firm at scale, and how accounting teams are eliminating it entirely.

Why the Manual Workflow Exists

QuickBooks Online and UltraTax CS are both best-in-class tools in their respective categories. But they belong to competing ecosystems — Intuit and Thomson Reuters — and there is no native integration between them.

That means every time you close a client's books in QuickBooks Online, you face the same choice every other QBO-using CPA faces: manually re-enter the trial balance into UltraTax CS, export to a spreadsheet and manipulate the data into the right format, or find a workaround that still requires time and attention to maintain.

Most firms have lived with this for years. It's not efficient, but it's familiar. And familiarity makes it easy to underestimate the cumulative cost.

What 1 Hour Per Client Actually Costs

One hour per client sounds manageable — until you do the math across your full book of business.

A firm with 30 active clients loses roughly 30 hours per tax season to trial balance re-entry alone. At $75–$150 per billable hour, that's $2,250–$4,500 in staff time spent on data transfer instead of tax work. For firms with 50 or 100 clients, the numbers scale accordingly.

And these are conservative estimates. They don't account for the time spent catching and correcting errors introduced during manual entry — a transposed digit, a miscategorized account, a line accidentally left blank. Each of those creates a downstream review cycle that adds more time per return and raises the risk of a filing mistake.

The true cost of the manual workflow isn't just the hour. It's the error rate that comes with it, and the review burden that error rate creates.

How AccountantSync Closes the Gap

AccountantSync is a direct integration between QuickBooks Online and UltraTax CS. Instead of manually re-keying trial balance data between the two systems, AccountantSync connects to your QBO account, pulls the trial balance, lets you map accounts to the correct UltraTax CS fields, and generates an import-ready file for UltraTax CS.

The workflow looks like this:

  1. Connect your QBO file — AccountantSync connects to your QuickBooks Online account via the QBO API. No exports, no CSV manipulation, no copy-paste.
  2. Map your accounts — The first time you set up a client, you map their QBO chart of accounts to the appropriate UltraTax CS input fields. AccountantSync saves that mapping — you only do it once per client, then it carries forward every year.
  3. Generate the import file — When you're ready to prepare the return, AccountantSync produces an import file formatted for UltraTax CS in seconds.
  4. Import to UltraTax CS — Load the file into UltraTax CS and the trial balance data populates automatically. No re-keying required.

What previously took an hour now takes minutes. The initial account mapping is a one-time setup cost that pays for itself the first time you run a return — and every return after that.

What This Looks Like at the Firm Level

For a solo CPA managing 25 clients, eliminating roughly 1 hour per client means reclaiming 25 hours over the course of tax season. That's time that can go into higher-value advisory conversations, additional client capacity, or simply finishing the season without burning out your team.

For a small firm with two or three staff members, the math compounds. Every hour of staff time saved on mechanical data entry is an hour that can go into return review, client communication, or onboarding new clients — the activities that actually grow the practice.

The firms seeing the most benefit are those where QuickBooks Online is the dominant bookkeeping tool across their client base. If 20 of your 30 clients are on QBO, AccountantSync immediately addresses that entire segment of your workflow.

One important note: AccountantSync currently supports QuickBooks Online and UltraTax CS. Support for QuickBooks Desktop and other platforms is coming soon.

Getting Started Is Free

AccountantSync includes a free tier that covers 2 clients — enough to test the full workflow with real client data before committing to a paid plan.

Setup for a new client takes less than 15 minutes. Connect your QuickBooks Online account, map the chart of accounts to UltraTax CS fields, and run your first import. If it doesn't save you meaningful time on that first return, you'll know immediately — and you haven't paid anything.

For firms ready to extend the workflow across their full client base, paid plans are available at accountantsync.com/pricing.
