About this app

Do you run a business in the Netherlands and paperwork is eating up your evenings?

Owlix (an online accounting app for Polish ZZPs in the Netherlands) keeps your invoices, expenses, and mileage allowances in one place. And when the bill comes due, you send everything to your accountant with a single click.

No binders. No digging through your pockets for receipts.

- An invoice typed up in Word in the evening
- Receipts from six months ago in your toolbox
- A call from your accountant: "I'm still missing a few documents"
- Mileage calculated from memory

Sound familiar?

WHAT OWLIX DOES

INVOICES - Issue in seconds. You download the contractor's details from the National Accounting Office (KvK), and it automatically calculates and numbers the invoices. You add your own logo and send the PDF straight from your phone.

• Look like a company, not someone writing invoices in a notebook.

EXPENSES — Snap a photo of the receipt with your smartphone, and the app will read the data from the document. You just check and approve. The cost is added.

• No receipt gets lost on the way to settlement.

MILEAGE — Enter the route, and the app converts kilometers into the deduction amount.

• Records are kept on the fly, not the night before the due date.

ACCOUNTANT REPORT — One click and your accountant receives the complete package: sales invoices, expenses, and mileage allowance, all organized in one package.

• Your conversation with the office starts with a "thank you," not a list of missing items.

CUSTOMER DATABASE — Customer data is at your fingertips.

• New order? Create an invoice in just a few clicks, because everything is already entered.

COMPANY DASHBOARD — See your turnover, costs, profit, and balance in real time.

• Know how much you're actually getting in your pocket, without waiting until the end of the quarter.

FACTORING — Don't want to wait 30 days for a transfer from the client? You can submit your invoice for factoring and get paid sooner. The service is managed by a financial partner, and each submission is verified.

• The money for the work performed stays with you, not the client.

IN POLISH, THE LANGUAGE OF THE CONSTRUCTION SITE

No accounting jargon. Simple steps, tips for every field, and numerical examples. Owlix is ​​designed for people who work in the field.

HOW TO GET STARTED

1. Create an account — just an email.
2. Complete your company details (KvK, BTW) — once, in just a few minutes.
3. Issue your first invoice.

…and you're done!

YOUR ACCOUNTANT ALSO BENEFIT

If your accounting firm uses the Owlix dashboard, documents are delivered to it instantly—no emails or reminders. You grant permissions and can revoke them at any time. Accountants access the dashboard via a browser, not a mobile app.

Owlix organizes documents and forwards them to your accountant. We don't do your accounting or provide tax advice—accounting decisions are left to your firm.
