I help small businesses with financial insights, structure and handling - the day to day stuff and the big picture stuff.

What's in it for you?

Know your finances and project margins, estimate better when scoping, get a better overview and optimize your business.

Budgets, forecasting, expenses, bookkeeping, payments, processes, invoicing, reporting

- I got this!

Focus on the team and the clients. Let me handle your finances, so you can focus on doing what you love.

Yes please!

How does it work?

I work from my office at Nørre Allé in the middle of Aarhus, when I'm not visiting clients for meetings. Whether you prefer onsite or online meetings, and how often we do a check in, is up to you. And in between, you can catch me on Slack, email or phone. We will of course have a conversation about our expectations to ensure a smooth and succesful collaboration.

Prices:

Bookkeeping: DKK 500,- /hour excl. VAT
Financial/business controlling: DKK 950,- /hour excl. VAT

If you need me to take care of all things finance for a fixed monthly fee, that's an option as well - let's talk!

What do the clients say?

"Lonnie is Ground Control – and an indispensable part of our team.

Although she is an external advisor, she feels like a permanent part of our organization. She handles everything in finance – from accounting and invoicing to banking and payments – with a precision and structure that ensures that we always have a full financial overview. Her insight enables us to make strategic decisions based on a strong financial foundation. But Lonnie's role doesn't stop there. She is an active part of our team planning each week and helps ensure that our projects run smoothly – not only for us as a company, but also for our employees and clients. Her solution-oriented approach and ability to create an overview make her an invaluable resource that creates calm, structure and efficiency in a busy everyday life. And most importantly - Lonnie is a pleasure to work with. She combines sharp professionalism with a positive and committed approach, which makes her a crucial part of our daily work."

Sophie Haack, founder, USE Agency

I’ve had the pleasure of working with Lonnie from Ground Control, and I can confidently say that her expertise has been invaluable to both Dunhammer and me.

Lonnie has my back across a wide range of financial tasks, including financial management, accounting, invoicing, budgeting, planning, and coordination with my accountant and bank. Everything you could dream of when, like me, you have a declared life goal of working with Excel sheets as little as possible.

Her meticulous attention to detail and structured approach have given me a clear financial overview, enabling me to make well-informed strategic decisions — and, more importantly, sleep better at night knowing that everything is under control.

Beyond her financial expertise and sharp, practical mindset, she brings a valued pragmatic and solution-oriented approach. Her ability to create clarity has made her an indispensable wing-woman, bringing calm, structure, and efficiency to a busy workday — where sometimes, all you need is a reassuring "We'll figure it out."

Working with Lonnie is always a pleasure; she combines sharp professionalism with a positive and engaged attitude, making her an essential part of my work and our operations.

Daniel Kowal, founder, Dunhammer
