Winstwaker – automated bookkeeping with a real accountant attached
2 comments
Possibly not for Dutch tax administration but this concept has been done in many other countries. It's a great idea though especially if your market hasn't been tapped yet.
In Germany we have several accounting software solutions like that for 5-10+ years that integrate with bank accounts, paypal, etc. - automatically suggests booking accounts and exports it via a REST API to the software accountants use. Accountants have access to it. Is this basically the same as your solution?
I built Winstwaker, a bookkeeping service for Dutch businesses that pulls transactions directly from your bank and hands the clean data to a dedicated accountant.
Running a small business in the Netherlands means dealing with a lot of admin. Most owners either hire a bookkeeper they rarely hear from or suffer through accounting software they don't fully understand. I wanted something in between. We built direct API connections to ING, Rabobank, ABN AMRO, bunq, and several others.
Receipts, Mollie payouts, Stripe transactions, Shopify orders — it all flows in automatically. Your accountant sees the same live data and reaches out proactively instead of waiting for year-end panic. No manual exports, no chasing invoices, no surprise tax bills.
Would love feedback from anyone who has dealt with Dutch tax administration or built similar hybrid service products.
