FAQ

Questions, answered.

How does Dunnfin connect to Younium?

Read-only OAuth. We pull invoices, contacts and payment terms — and write reminder activity back as notes on each invoice.

Can I customize reminder copy?

Yes. Templates per cadence, with merge fields for invoice number, due date, balance, and accrued interest. Localized per customer.

How are interest fees calculated?

You set an APR and compounding (daily, monthly, simple). Dunnfin applies it from the invoice due date and posts a line back to Younium when paid.

Will customers know it's Dunnfin?

No. Reminders send from your domain via your SMTP or Gmail/Outlook connection. Customers see your finance team, not us.

What if a customer disputes a reminder?

Pause reminders per customer or invoice with one click. The pause is logged and synced back to Younium for audit.

Is my Younium data secure?

SOC 2 Type II. EU-hosted (Frankfurt). Read-only scopes by default. Full audit log of every action exported on demand.

Stop chasing. Start collecting.

Connect Younium, set your cadence, and let Dunnfin run AR while you do the closing.
