From blank to sent invoice in half a minute. Professional, fully legally compliant, and instantly payable via iDEAL or credit card.
Every time you need to copy a Word file or Excel sheet, adjust it manually, and hope the formatting holds. Slow and error-prone.
A valid invoice must meet specific legal requirements. Miss one field and the client can legally refuse to pay.
You send the invoice and wait. Following up feels awkward, but late payments hurt your cash flow.
Pick a client, add your line items, and send. Client details, VAT, and invoice number are filled in automatically.
All mandatory fields included automatically: KVK number, VAT amount, payment terms, and your full address details.
Every invoice includes an iDEAL payment link. Clients pay directly from the email — an average of 11 days faster.
Declair sends polite reminders when an invoice is overdue. You don't have to lift a finger.
Choose an existing client or quickly add a new one. KVK validation ensures everything is correct.
Products, services, or hours — save them as recurring items for even faster invoicing next time.
Send the invoice by email with an iDEAL payment link. Get notified the moment payment comes in.
“My VAT return now takes 5 minutes instead of a whole evening. All invoices are neatly stored in the system.”
“Invoices get paid an average of 2 weeks faster since I started adding an iDEAL payment link. That's a huge difference.”
“I hate admin work, but with Declair I barely notice it. Creating an invoice literally takes me a minute.”
