You don’t need another accountant.

You need someone who gets the business—not just the books. 

That’s why LedgerLine exists. 

LedgerLine offers everything you’d expect from an industry-leading cloud accountant and financial expert—plus a few valuable extras you didn’t know you needed. 

From bookkeeping, payroll, and reconciliations to year-end reporting, tax planning, audits, and financial advice — we take the weight off your shoulders and make sure nothing falls through the cracks. 

We’re not just here to keep things compliant. We’re here to keep you confident — with systems that make sense, reporting you can rely on, and a team that’s easy to reach and even easier to trust. 

That’s why
Stefan Armstrong
started LedgerLine. 

To take what he’s learned, from turnarounds to cleanups to CFO-level strategy, and give leaders the kind of financial partnership that actually moves things forward. One built on clarity, responsiveness, and modern systems that make sense.

You didn’t build your business to get buried in the books. We take the financial weight off your shoulders — from payroll and bookkeeping to tax strategy, audits, and year-end prep—so you can make smart decisions with clarity, not guesswork. It’s the kind of proactive, responsive support every leader deserves.

Yes, we do the work. But more importantly, we make sure it works for you. Because when your finances are clean, your decisions are sharper. And when you stop chasing numbers, you finally get to lead.
