What our clients say

★★★★★

“We have an ecommerce store - Art and Crafts Press. When an app we had installed (that was meant to simplify our lives) instead took a whirl through our Quickbooks accounts and all of the records were messed up,, we were thankfully referred by our lawyer to Fiona Nguyen at Balannx. Fiona and her crew were able (on a very, very tight deadline) to not only unscramble our Quickbooks financials, recreating a years worth of transactions, but also install an appropriate app that did simplify our lives, and even consult us on how to use it. We were able to file tax return on time within a tight deadline. And they far exceeded our expectations, and all this with a smile. We look forward to working with them again.”

“Ok my dear colleague and now friend Fiona Nguyen tagged me on this over a week ago, but I wanted To wait to share when I had the time and clarity to really speak her brilliance. If I had to name the top 5 most influential people to my business growth Fiona would be undeniably within the top three. First of all not many people would say this about their accountant, bookkeeping team or CFO, but I can squarely and wholeheartedly say she has changed the trajectory of my business. As someone who grew up in feast and famine I always thought that simply making more money was the answer. The truth is I had to do more than that. In 2017 I made $200k MORE than I had accounted for… that sounds great but WHERE was It? In 2022 one of my highest grossing years and with Fiona handling my taxes and bookkeeping not only did I pay 50% less tax than I had the previous year when I made less money with a different accountant! Most importantly, I know my numbers. i know what the business can afford, what to put away for taxes, how much I can invest in growing my business. At a glance with the systems she’s helped me implement I can see how close I am to goals, or if there are any leaks in my business that need to be tended to before they become a problem. What she’s done is not just help, she’s teaching me every month how to be a better CEO. If you are feeling shame about your money, past bad money decisions, or just want 2024 to really kick butt I’d highly recommend getting her on your money team. Love you to the moon and back Fiona! xoxo Brandi Jordan - founder the Cradle ”

“Fiona changed my life! I call her my Angel. She came in when my husband suddenly passed away, and helped me figure out his completely messed up business. I paid off his business debts $35Mil in 3.5 years while building cash flow and business You cannot imagine the pressure and stress that I was under that time. Yet, Fiona brought her incredible financial and accounting knowledge, and a strong mindset, intelligence, and business strategies to help me solve the challenges during the tough time. I am forever grateful for what she helped me. ”

“she'll never ask for this post and is incredibly humble but I have to shout out the most amazing CPA, accountant, Bookkeeper and CFO there is: Fiona, Fiona Nguyen Before I go on, understand that I'm not and cannot be an affiliate. FIona and I can't be that for one another because of our professional licenses and ethics boards. This is simply a legit shout out because rarely do you encounter someone so committed to your mission and vision at your own pace Like Fiona. The last two years I've seen massive growth in my business while simultaneously encountering some of the most intense challenges I could have imagined (life threatening medical issues and our home/car/possessions/community burning and all that accompanies both those things). And the last 6 months have brought big decisions including shifts and pivots that don't always make sense, from closing down some of our most profitable programs prematurely, ending contracts early, and having serious conversations about expenses and money and all the things. And now, we're preparing for our more public announcements and pivots and the pieces are falling into place. All the while, Fiona and her devoted and brilliant team are supporting all our data from 2023, and making me feel worthy all along the way no matter what we're earning or not. So if you're looking for a financial partner for your business, taxes done swiftly, and correctly, bookkeeping and strategy projections and a true friend in your journey, Fiona is your person. She probably has a waitlist by now but you'll be smart to join that list. Your future self will thank you! Photo of me and Fiona from this September ! Thank you, Fiona! Thank you for all you do, how you help, and your friendship too!”

Secure Onboarding

We connect to your accounting and payment tools (QuickBooks/Xero, Stripe, Gusto) safely and quickly.

Cleanup & Handoff

We reconcile the past, fix the errors, and hand off a set of clean books so you can start fresh.

When Clean Books Matter Most

Banks don’t lend on messy financials
Buyers don’t trust reconstructed reports
Due diligence punishes gaps and inconsistencies
Our cleanup work is designed to produce financials that stand up to scrutiny not just look tidy inside accounting software.

Cleanup for Founders & Owners 

For SaaS Founders:

MRR/ARR doesn't tie to cash.

Deferred revenue isn't tracked.

For Innovative Entrepreneurs:

Months behind on bank reconciliations.

Month-end close takes weeks, not days.

Cash vs. Accrual confusion.

P&L reports you don't trust.

For Services & Agencies:

Unbilled time and WIP is messy.

Owner expenses are mixed with business.

Contractor 1099s are incomplete.

Frequently Asked Questions

What is included in a cleanup?
We fix past errors, categorize uncoded transactions, reconcile bank/credit card accounts, and ensure your books are complete and tax-ready.
How much does it cost?
Cleanup is priced based on the volume of transactions and the number of months/years that need fixing. We provide a custom quote after our initial evaluation—no hidden hourly fees.
What software do you work with?
We primarily work with QuickBooks Online and Xero, along with tools like Bill.com, Gusto, and Stripe.
What happens after the cleanup?
Once your books are clean, you can transition into our ongoing Bookkeeping, Tax, or Fractional CFO services to keep them that way.

Your books don't have to be a source of stress. We’ll simplify the process and give you back your time.
