About Lochside Accounting
QuickBooks ProAdvisor in Houston, Texas. Serving clients across the country.
A Little About the Owner
Lochside Accounting was founded by Thomas Grant MacDonald, a professional QuickBooks bookkeeper and CFO for multiple startups. Thomas holds a B.A. from the University of Texas at Austin and a Master’s Degree from the University of Pennsylvania.
Thomas has been knee-deep in bookkeeping for years, helping over 1,000 business owners get their finances in order. He’s the kind of guy who loves untangling messy records and turning them into something clear and manageable.
A self-proclaimed nerd for systems and software, he’s always hunting for better ways to make businesses run smoother, and he never says no to learning something new.
As a USAF veteran, Thomas developed a knack for staying calm and organized, even when things get intense. He’s a certified QuickBooks ProAdvisor, bringing top-notch skills to the table.
Since January 2025, he’s been a certified QuickBooks ProAdvisor. He’s also a 50% owner and CFO of a startup, so he knows how to plan money for growing businesses.
All of that shapes how Lochside Accounting serves its clients. Whether you’re a small business owner juggling everything, a builder managing projects, or a property investor growing your portfolio, Lochside is here to make your financial life easier.
Our team brings real-world know-how, technical expertise, and a friendly approach to every job. We’re not just about numbers—we’re about building systems that work for you, saving you time, and reducing stress so you can focus on growing your business.
Based in Houston, Texas, Lochside works virtually with clients all over the U.S. We believe there’s always something to be thankful for, even on tough days. To us, a good laugh is just as important as a balanced ledger. If you’re looking for practical help with a bit of personality, Lochside is your team.
Why We Do What We Do
Lochside LLC was created to make managing money easier for busy business owners.
Our clients are often out working—running projects, building homes, or managing properties—with no time for bookkeeping.
Payroll usually gets handled.
But it’s those quarterly payments, messy reconciliations, and forgotten 1099s that slip through the cracks.
Hiring more admin staff can help, but it also adds overhead and more people to manage.
