Case Study
Banking in SnelStart Bookkeeping
SnelStart, trusted by thousands of accountants and businesses, now offers SnelStart Bankieren—a fully integrated banking solution powered by Flow.
Seamless Banking Integrated into Accounting
SnelStart has been helping small businesses and accountants manage their finances for decades. With over 5,100 accountants and hundreds of thousands of business users, they know the daily struggles of financial admin. Flow partnered with Adyen to help SnelStart launch SnelStart Bankieren—a fully integrated banking experience that eliminates friction, automates financial workflows, and puts businesses in control of their cash flow. No more switching between apps. No more manual transaction matching. Just a business bank account built right into accounting, where it belongs.
The Problem
Disconnected Financial Services
Businesses rely on multiple financial tools—a bank for transactions, accounting software for bookkeeping, payment links for invoices, a POS system for sales, and sometimes a lending product. While essential, these services don’t work together, creating unnecessary complexity.
Setting up and maintaining them is a hassle—each service requires separate onboarding, verification, and manual integrations.
They don’t share data or intelligence, meaning businesses waste time linking systems, reconciling transactions, and doing double work.
Costs are higher—banks and service providers charge extra simply to connect, treating small businesses as individual clients rather than integrated financial operations.
Instead of streamlining operations, financial tools create more admin, more costs, and more inefficiencies.
The Solution
Everything in One Place
With SnelStart Bankieren, banking and accounting finally work together. Instead of juggling separate tools, businesses get a fully integrated financial system where transactions, payments, and bookkeeping are seamlessly connected. This eliminates manual admin, reduces costs, and makes managing money effortless.
Banking Integrated Directly into Accounting
A bank account that lives inside your accounting software means no more manual imports or transaction matching. Payments, expenses, and cash flow updates happen in real-time, directly in SnelStart.
Mobile Banking from SnelStart
Manage your finances anytime, anywhere. SnelStart Bankieren brings banking and payment actions from accounting to mobile, so businesses can stay in control on the go.
Money Automation That Saves Time
