How your invoice reaches us
Lexware Office
keeps invoices and payments
connected directlyDunningHero
sends reminders and dunning letters
Nothing is sent until you switch sending on
Connected directly
Connect once, and the invoices arrive by themselves.
DunningHero connects directly to Lexware Office. No export, no list to upload, nothing typed twice.
Sign-in
Sign in once with your Lexware Office account (OAuth) or add an API key.
What comes across
Customers, open and overdue invoices, payments and the original invoice PDF.
Always current
Where Lexware Office reports changes by webhook, an invoice reaches us seconds later — otherwise the regular sync picks it up.
Partial payments, credit notes, cancellations and invoices on payment terms that are not dunned are recognised and handled correctly.
The difference
What Lexware Office does and what comes after.
From a menu item to a schedule.

Dunning means: open the invoice, choose “Mahnen”, send — one invoice at a time.
With DunningHero
Overdue invoices are reminded and dunned on your schedule, without anyone opening a document.

The Lexware Office help centre describes no automatic sending of dunning letters. Remembering the next level is up to you.
With DunningHero
Six payment reminders and three dunning levels, each with its own deadline and wording. A payment ends the chain.

It goes out by email, or you print it yourself. As far as we found, postal sending only comes through partner apps, and there is no text messaging.
With DunningHero
Email, a short text message alongside, and the letter we print, envelope and post — as an Einwurf-Einschreiben from a level you choose.

Features
What runs by itself from then on.
Up to nine levels
Six payment reminders and three dunning letters, each with its own deadline, wording and tone.
No login needed
The run follows your schedule. You hear from us because something went out — not so that it can.
Payment stops the chain
Once the amount is settled in your accounting system, the next sync ends the escalation.
Text and letter, not just email
As add-ons: a short text message alongside the level and, when needed, a letter we print and post — for customers who overlook email.
Dunning fees and interest
A €5.00 fee per dunning level by default, freely adjustable, never on a payment reminder. Default interest from the day of default — at the consumer rate or, via a setting, the business rate.
Pause instead of switching off
Pause a single invoice or a whole customer — one click, with the reason kept in the audit trail.
Pricing
Priced by overdue invoices in flight.
Not per seat, not per revenue. Annual billing is 15% cheaper.
