Invoices and payments
A single invoice a month, paid by the direct debit you authorise just once.
How it works
- At the end of the month you get a single invoice with the orders delivered that month.
- The same invoice includes your paid changes: the first change on each item is free, every further one costs €5.00.
- If an order is cancelled after work has started, the same invoice has the line “Orders cancelled after work started”: what it costs is explained in Cancelling an order.
- It's paid by SEPA direct debit: you authorise it once and then there's nothing else to do.
- An order delivered after the month closes goes into the following month's invoice.
- If you request a change after delivery, the order goes back: it goes into the invoice of the month it's Delivered again.
- VAT is calculated according to your country and your billing details.
Setting up payments
Open My account, Payments tab. You do it once, in two steps: first your billing details, then direct debit.
- 1
How we invoice you
The details we issue your invoices with, and where we send them.
- 2
How you pay
SEPA direct debit with your IBAN. Once signed, the status updates by itself.
Without billing details and direct debit you can't send an order. If they're missing when you confirm, we ask for them right there and the filled-in order isn't lost.
Your invoices
In Invoices the “Next Orders invoice” box tells you how much you've built up this month and when the invoice is due. Below it is the history: for each invoice the date, amount, status and the PDF to download.
Where needed, next to the PDF you'll also find the XML file to import into your management software. The invoice is in Italian or English.

How does invoicing work?
You receive a single invoice per month: it includes the orders delivered during the month, any paid changes, any orders cancelled after work started and any monthly plans (Dentra Viewer PRO, Oralsnap plans). The amount is collected automatically via the SEPA direct debit you authorised once; if direct debit is not active, the invoice is settled by bank transfer within 30 days.
What payment methods are accepted?
SEPA direct debit from your business account: you sign the mandate once and from then on the end-of-month invoice is paid automatically, with no bank transfers. We don't accept credit cards, PayPal or cash on delivery. If direct debit is not active, you pay by bank transfer to the IBAN shown on the invoice.
When do you ask for my IBAN?
Only when you send your first order or activate a paid plan. If your bank hasn't activated the mandate yet, you can still order.
In which countries can I sign the SEPA direct debit?
Throughout the European Union and in Iceland, Liechtenstein, Norway, the United Kingdom, Switzerland, Monaco, San Marino, Andorra and Vatican City.
Who issues the invoice and how does VAT work?
Invoices are issued by Hundredjack OÜ, an Estonian company. In the European Union, if you have a VAT number, the invoice carries no VAT (reverse charge) and you account for VAT under your country's rules. In Estonia, Estonian VAT applies. In the United Kingdom and Switzerland the invoice is outside the scope of EU VAT.
Do I get a file for my accounting software?
Yes, for Italian clients we attach the XML integration file (TD17) to the invoice, ready to import into your accounting software as required for purchases from an EU supplier.
What language is the invoice in?
In Italian if you use Dentra in Italian, in English for all other languages.
I'm in the United Kingdom and don't have a VAT number: can I use Dentra?
Yes. In the United Kingdom your company number (Companies House) or your GDC number is enough: you only add a VAT number if you have one.
Do I need to provide an SDI code and PEC address?
No. To invoice you we only need your company name, VAT number and address.
Where can I find my invoices?
In your account, under Invoices: you can download the PDF of each invoice and, if you are in Italy, the XML integration file too.
