Getting paid
Payment reminders
Automatic reminder emails to your client, timed around each invoice's due date — negative numbers are days before due, positive are days overdue. You're notified each time one goes out. Reminders that fall before an invoice was sent are skipped automatically.
VAT & OSS
If you sell digital services to consumers in other EU countries, or ship goods to them, and those sales exceed €10,000 in a calendar year, you may need to charge the customer's country's VAT. OSS is the simplest way to do that. Register at SKAT →
Bookkeeping
How to connect Billy (now Shine) →
Does your business have to keep its books digitally under the Danish Bookkeeping Act? Then keep every invoice and credit note in your bookkeeping system, as issued. PennaPay is not a bookkeeping system.
E-invoicing
Client messages
Where messages to your clients are delivered. Email is always on — it's the reliable fallback. Turn on Telegram to let clients who link their Telegram receive your messages there; you choose the channel per conversation in Messages.
Always on — the non-removable fallback.
Telegram
Clients who link Telegram get your messages there.

You're on the Pro plan. Unlimited invoices, all templates, priority support.

Passkeys
Sign in with Windows Hello, Touch ID, iCloud Keychain, Google Passkeys, or a hardware security key — no password needed. Password remains as a fallback.
Remove this passkey? You will no longer be able to sign in with it.
Two-factor authentication (2FA)
Add an extra layer of security. After enabling, you'll need your authenticator app (Google Authenticator, Authy, etc.) each time you log in.
Scan this QR code with your authenticator app, then enter the 6-digit code to confirm.

Your data
Data export
Download a copy of all your data (GDPR Art. 20 — right to portability).
The CSV opens in Excel and Google Sheets.
Delete account
Schedules your account and all data for deletion. You have a 30-day window to restore your account. After 30 days, all data — including your invoices, contacts and uploaded files — is permanently erased.
Under Danish Bogføringsloven § 12 you are required to retain your bookkeeping records for 5 years. As the data controller for your invoice data, you must download and store a copy before deletion — we do not retain a copy on your behalf.
AI & Privacy
Control which AI features can process your data. These settings apply to your account. Per-contact overrides are available inside each contact's workspace.
All AI features use Claude (Anthropic). Data sent to Claude is governed by Anthropic's Privacy Policy. PennaSystems does not use your data to train AI models.
