paywise for sevdesk

sevdesk
The sevdesk integration hands open invoices from your sevdesk account straight to paywise for collection. sevdesk supplies unusually much: the payment term, recorded partial payments, and your reminders including dunning level and dunning fee.
paywise reads from sevdesk and never writes back. Nothing in your bookkeeping is changed, cancelled or marked as paid.

​
Before you start

  • A sevdesk account with API access.
  • A paywise account.
  • At least one completed, open invoice in sevdesk.
  • No active DATEV import may exist for your paywise company. Deactivate it under DATEV Einstellungen → Gefahrenzone → Integration deaktivieren before connecting sevdesk.

​
What paywise reads

The API token is used read-only.

​
Finding your sevdesk API token

Inside paywise this guide is available at any time via „Was ist das?“ (what is this?) on the sevdesk page.
1

Sign in to sevdesk

Sign in to your sevdesk account at my.sevdesk.de.
2

Open the API section

In the menu, go to Erweiterungen → API (Extensions → API).
3

Reveal the token

Click Einblenden (show) to display the API token.
4

Copy the token

Copy the key to your clipboard.
The API token covers your entire sevdesk account. Never share it by email or chat.

​
1. Connect sevdesk

1

Open the connection page

Go to app.paywise.de/connect/sevdesk/.
2

Paste the token

Paste the key into the API-Token field. The API Basis-URL is pre-filled with https://my.sevdesk.de/api/v1 and normally needs no change.
3

Accept the terms and test

Tick Ich akzeptiere die Nutzungsbedingungen (I accept the terms of use) and choose API-Token testen (test API token).paywise verifies the token directly with sevdesk. If the check succeeds, the connection is saved immediately.

​
2. Submit invoices for collection

1

Open the invoice picker

On the sevdesk page in paywise, choose Rechnungen einreichen.
2

Pick the invoices

paywise lists your open invoices live from sevdesk — with invoice number, customer, invoice date, due date, total and open amount.paywise derives the due date from the invoice date plus the payment term stored in sevdesk. Nothing needs to be configured in paywise for this.
3

Check the debtor data

Name and address come from the sevdesk contact, the invoice PDF is attached automatically. Review and correct anything missing.
4

Review the reminders

Reminders you created in sevdesk for the invoice are imported automatically — with reminder date, payment deadline and, where charged, the dunning fee of the respective dunning level. If you dunned outside sevdesk, add that by hand here.
5

Send the order

Confirm how collection should start, answer the legal questions, accept the terms and choose Auftrag absenden.

​
Invoices that cannot be submitted

  • Drafts and unfinished invoices. paywise reads only completed sevdesk invoices.
  • Incomplete recipient details. paywise imports the invoice as an editable draft. Complete the name and address in paywise before submitting the order.
  • Already submitted invoices are shown as Eingereicht.

​
Mahnservice: importing invoices continuously

This integration feeds more than the one-off collection handover — it can also supply the paywise Mahnservice, the pre-collection dunning service. paywise then fetches your open invoices regularly and sends payment reminders on your behalf, before a case becomes a collection matter. You set the Mahnservice up at app.paywise.de/mahnservice/.

​
Prerequisites

All of the following must be in place before the recurring sync starts:
  • An active sevdesk connection with a valid API token.
  • A Mahnservice subscription and the accepted Mahnservice terms.
  • A decided import scope — you determine once which invoices should be taken over.

​
What paywise checks before every reminder

1

Regular sync

paywise fetches your open invoices from sevdesk at fixed intervals. Newly opened invoices are picked up automatically.
2

Status check immediately before sending

Right before a reminder goes out, paywise queries the current invoice status in sevdesk once more. If the invoice has been paid or cancelled in the meantime, no reminder is sent.
3

When in doubt, nothing is sent

If the status cannot be established beyond doubt — because sevdesk is temporarily unreachable, for instance — paywise holds the reminder back. That is deliberate: a reminder sent late is better than one sent to somebody who has already paid.
Payments paywise finds in sevdesk during a sync end the dunning process automatically.

​
3. Disconnect

On the sevdesk page, choose Verbindung löschen (delete connection) and confirm with Löschen. paywise removes the stored token and stops reading invoices. Orders you already submitted are unaffected. paywise pauses running dunning processes that depend on this connection. You can resume them after reconnecting.
The token itself stays valid in sevdesk. To invalidate it completely, reset it in sevdesk under Erweiterungen → API as well.

​
Troubleshooting

Check that you copied the full token (no leading or trailing spaces) and that the API base URL is unchanged.
The token was reset or revoked in sevdesk. Fetch a current token under Erweiterungen → API and store it again.
paywise shows only completed, open invoices. Drafts do not appear. Check the invoice status in sevdesk.
paywise subtracts payments recorded in sevdesk from the gross amount. A payment not yet assigned to the invoice in sevdesk does not show up here. Assign it in sevdesk and reload the list.
Another import source conflicts with sevdesk. If the message names a DATEV import, deactivate it; disconnect any other integration named there. Then try again.
