Features
Everything to invoice and do your own administration — explained in plain language.
Tidy invoices in your own branding
Create a professional invoice with your own logo and colours in a few clicks. Everything the law requires is on there automatically — you don't have to think about it.
Get paid faster
Every invoice carries a QR code: your client scans it with their banking app and the exact amount is ready to send. Or let clients pay online with iDEAL — even direct debit is possible.
Reminders happen automatically
Invoice overdue? We automatically send a friendly reminder, followed by a formal demand if needed — neatly within the legal rules. You don't have to chase anyone.
VAT returns without the stress
Every quarter you see exactly which amounts to fill in at the tax office. No maths, no doubt: copy them over and you're done.
Receipt? Snap a photo, done
Take a photo of your receipt or forward the invoice to your administration's email address. The details are read and filled in automatically — you only give it a quick check.
Always know where you stand
How much have you earned this year? Who still owes you money? You see it at a glance — no Excel and no bookkeeping jargon.
Quotes clients sign online
Send a quote and let your client approve it online, no printing or scanning. Approved? One click turns it into an invoice.
Recurring invoices run themselves
Billing the same amount every month, say for a subscription or maintenance contract? Set it up once and the invoice goes out by itself from then on.
Tracking mileage pays off
Driving your private car to clients? Log your trips: the mileage allowance is processed into your books automatically, and billing it to your client takes one click.
Import bank statements
Download your statements from your bank and import them. Payments are matched to the right invoices automatically, so you instantly see what's still outstanding.
Big purchases handled properly
Bought a laptop or machine? The tax office doesn't let you claim purchases like that as costs in one go. We spread the cost over the years automatically — nothing for you to worry about.
Ready for e-invoicing
More and more clients and the government ask for e-invoices. Katsjing creates one automatically with every invoice — you won't notice a thing, but you're ready.
Switch in an afternoon
Coming from Moneybird or e-Boekhouden? Bring over your clients, invoices and figures in a few clicks. Cancelling your old package is the hardest part.
Collaborate if you want to
Working with a colleague, or with an accountant after all? Invite them into your administration and decide yourself what they can see and do.
Also in Dutch
Dutch client? Send your invoice or quote in Dutch. The app itself works fully in both English and Dutch.
