How a 7-Partner DA50 Group Automated Their Entire Admin

Seven partners sharing a Diamond DA50 in the Netherlands. Great airplane, great group — a lot of admin.
Every month, the same routine. Calculate everyone's hours. Create invoices. Send them out. Chase the late ones. Then manually enter everything into Yuki. Match payments. Handle VAT. Repeat.
For one airplane and seven people, this took hours every month. Not flying hours — spreadsheet hours.
They connected two things
The group connected their Stripe account for payments and their Yuki account for accounting. That's it.
Now the flow looks like this:
- Someone flies and logs their hours in Kai
- Landing fees are added automatically for airports where the group has an account — when ATC fees come in later, they're easily matched to the specific flight
- Kai calculates the total cost based on the group's rates
- An invoice is generated
- The member pays online via Stripe
- The invoice automatically syncs to Yuki
- VAT is handled — no manual entry
From flight to fully reconciled books, nobody has to touch anything.
The VAT detail that matters
Because invoices automatically flow into Yuki, the group can file their quarterly BTW return to the Belastingdienst directly from Yuki — without re-entering anything.
No manual VAT calculations. No recreating invoices in a different format. The data is already there, structured and ready to submit.
Setting it up
The Yuki integration takes about two minutes:
Settings → Accounting Integration → Yuki
Enter your API key and administration ID. Done.
Kai will sync invoices to your Yuki administration as they're created and paid. No CSV exports, no manual imports, no copy-pasting between systems.
The result
Monthly admin went from hours to basically nothing.
Invoices go out automatically. Payments come in through Stripe. Everything lands in Yuki without anyone lifting a finger. VAT is correct. The books are up to date.
The treasurer still reviews things — but reviewing is very different from doing it all by hand.
Not using Yuki?
Kai also integrates with other Dutch and European accounting platforms:
- Moneybird
- Exact Online
- e-Boekhouden
Same idea — connect your account, and invoices sync automatically. The specific features vary by platform, but the goal is the same: stop doing admin that software can handle.
This isn't just for aircraft
The same setup works for any shared asset — boats, cars, vacation properties. If your group creates invoices and needs them in an accounting system, this applies to you.
