For Papierkram users

Papierkram dunning, automated with fees, interest and a schedule.

In Papierkram you create and send every dunning letter yourself, and a dunning fee only gets in through a template tweak. DunningHero connects directly to Papierkram and duns on your schedule — with fees and default interest, by email, text message or post.

How your invoice reaches us

  1. Papierkram

    keeps invoices and payments

    connected directly
  2. DunningHero

    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 Papierkram. No export, no list to upload, nothing typed twice.

Sign-in

Your Papierkram subdomain and an API token — added once, done.

What comes across

Customers, open and overdue invoices and payments.

Always current

Where Papierkram 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 Papierkram does and what comes after.

Three levels by hand — or nine on a plan.

  1. 01

    Today in Papierkram

    You create each dunning letter on the invoice via “Mahnung erstellen” and send it yourself.

    With DunningHero

    Overdue invoices are reminded and dunned on your schedule — on the weekdays and at the time you choose.

  2. 02

    Today in Papierkram

    Three dunning levels; for a payment reminder you send the invoice again.

    With DunningHero

    Six payment reminders and three dunning levels with their own texts and deadlines; switch off the levels you don't need.

  3. 03

    Today in Papierkram

    There is no built-in dunning fee, only a workaround in the template.

    With DunningHero

    A fee per dunning level and default interest under § 288 BGB, calculated from the day of default and shown as its own line.

How it works

Connected in four steps.

  1. 1

    Connect Papierkram

    Sign in once or add a key — after that there is nothing left to transfer.

  2. 2

    Invoices arrive

    Open and overdue invoices, customers and payments appear in DunningHero and stay current.

  3. 3

    Set your levels

    Deadlines, texts, channels and fees per level — or take our templates. Free for 14 days.

  4. 4

    Switch sending on

    Nothing goes out before you allow it. Until then you only see what would happen.

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.

FAQ

Questions from Papierkram users.

See everything DunningHero does
How do I connect Papierkram?
With your Papierkram subdomain and an API token. From then on customers, open and overdue invoices and payments reach DunningHero by themselves.
Can the dunning letter go by post?
With the postal add-on: we print, envelope and stamp the letter and hand it to the post, as an Einwurf-Einschreiben from a level you choose. The tracking number then appears on the case.
Will a customer get two letters?
Only if you keep dunning by hand in Papierkram as well. Let dunning rest there once DunningHero takes over sending — then your customer gets exactly one letter per level.
