What is Finance Stacks?

Finance Stacks helps businesses find the perfect combination of finance tools – tools that are not only great individually, but work seamlessly together. Because the best accounting software is of little use if it doesn't sync with your bank, your invoicing tool, and your cash flow planning.

We call these combinations "Stacks" – carefully curated sets of finance apps connected through native integrations, APIs, or standardized interfaces like DATEV. Each stack is optimized for a specific business type: freelancers, startups, agencies, e-commerce, and more.

A core focus of our work is the compatibility matrix. We continuously invest in documenting and rating how well different tools work together – what data flows, in which direction, and how reliable the connection is. This platform is continuously being developed to make the compatibility score more and more precise.

Our goal: Give everyone the information they need to make informed decisions when selecting their finance stack – without hours of research, without costly mistakes.

How It Works

• Stacks — Pre-configured combinations of finance tools for different business types. Each stack includes recommended apps, alternatives, and estimated costs.
• Apps — Individual software tools for banking, accounting, invoicing, expenses, payroll, and more. Filter by category to find what you need.
• Services — Professional service providers including tax advisors, legal services, and consultants.

Why We Built This

Marcus, the founder of Finance Stacks, repeatedly faced the same frustrating challenge: finding the right finance tools for his businesses. Every new venture meant hours of research, comparing dozens of apps, reading conflicting reviews, and often making expensive mistakes with tools that didn't fit.

After going through this process multiple times — for startups, agencies, and consulting businesses — he decided to build what he wished had existed: a curated, honest directory where founders can quickly find the right financial infrastructure for their specific situation.

Every stack and recommendation is based on real-world usage and practical experience running businesses.

Our Commitment to Neutrality

Finance Stacks is committed to being a neutral platform. We evaluate all apps using the same criteria, regardless of business relationships. No app receives preferential treatment — not even those we have connections to.

Our ratings come from real users and team members who actually use these tools. We clearly mark team reviews so you always know who is reviewing. We believe transparency builds trust, and trust is the foundation of useful recommendations.
