Our Story

Accounting Services Unlimited was founded in New Orleans with one mission: to give small business owners their time back. What started as a locally owned firm serving the Greater New Orleans area has grown to serve businesses across Louisiana and as far as San Diego, California — all built on the same foundation of accuracy, accountability, and genuine partnership with our clients.

As a locally owned and staffed business, we understand the challenges and rewards of operating a small business. Our entire accounting firm is geared toward removing the burden of accounting and bookkeeping so you can focus on the core activities in your business.

We Go Where You Do

ASU started in New Orleans, but your business doesn't have to be local to work with us. We serve clients remotely across the United States through QuickBooks Online, secure document sharing, and video consultations.

If you're a Louisiana business owner who has relocated, a California client with Louisiana ties, or a small business owner anywhere in the country who needs experienced accounting support — ASU can help. No office visit required.
