About the Extension

Open Invoices & Dunning Management for Shopware 6 – free to start, plans on demand

This plugin gives shops that sell on account full control over their open invoices (receivables) and their dunning process – directly in the Shopware 6 Administration under Orders > Open invoices. Every order paid with an invoice payment method is tracked automatically as an open item until the payment status is set to “paid”. The free core is genuinely useful; optional plans (In-App Purchase) add dunning levels, automation, PDF letters and more – booked and cancelled directly in Shopware.

✅ Free – no plan required

Receivables dashboard with KPI cards: open amount, open invoices, overdue, in dunning
Traffic-light indicator per invoice (green: not yet due, yellow: 1–14 days, orange: 15–30 days, red: more than 30 days overdue)
Filters: search by order number, customer, company or e-mail, due-date range, amount range and dunning level
Payment reminder e-mail (once per invoice) using an editable Shopware e-mail template
“Mark as paid” – also sets the payment status of the order to paid
Automatic closing when the payment status changes to paid or the order is cancelled

? Optional plans (In-App Purchase)

Install for free and upgrade only when you need it. Plans are subscriptions you book directly in Shopware – current prices are shown in the In-App Purchase dialog in your Administration. Starter plan

CSV export of open invoices (respects the active filters)
Manual dunning levels: payment reminder, 1st and 2nd dunning notice
Bulk actions: send reminders, send the next dunning level or mark several invoices as paid at once

Business plan (everything in Starter, plus)

Automated dunning via a daily background task – payment reminder, 1st and 2nd dunning notice according to your day thresholds
PDF dunning letter as its own Shopware document type, attached to the e-mail and stored with the order
Automatic dunning fees per level, shown in the e-mail, on the letter and in the receivables list
Rule Builder conditions: “customer has open invoices”, “oldest open invoice overdue by X days”, “highest dunning level” – e.g. to hide the invoice payment method for customers with overdue invoices
Dunning history: every reminder, notice, letter and payment in one timeline

Pro plan (everything in Business, plus)

3rd (final) dunning notice with debt-collection announcement
Customer account view – logged-in customers see their own open invoices in the storefront (can be switched off per sales channel)
Daily e-mail to the shop owner listing invoices that have become overdue
Export of the dunning history as CSV or as PDF per invoice

Why this plugin?

Shops that offer payment by invoice quickly lose track of who still owes money. Checking due dates and writing reminders by hand costs hours every week. Start for free with a clear receivables overview and manual reminders – and switch on dunning levels, automation, PDF letters and fees exactly when your volume justifies it.

Fully editable

All e-mails (payment reminder, three dunning notices, owner notification) are regular Shopware e-mail templates in German and English under Settings > E-mail templates
Payment term, day thresholds per level, new payment deadline, fees and the payment methods treated as “invoice” are configurable – also per sales channel (the notification address applies shop-wide)
The dunning letter uses your company data and logo from the Shopware document settings
Access for administrators can be restricted via Users & permissions

System requirements:
Shopware 6.7. Automated dunning and the daily owner notification use the standard Shopware background worker (message queue & scheduled tasks), which is active by default on most managed hostings. All manual actions work without the worker.

Are existing orders imported?

Yes. Clicking "Synchronise orders" imports open orders from the last 365 days; the daily background task also keeps everything in sync automatically.

Yes. Clicking "Synchronise orders" imports open orders from the last 365 days; the daily background task also keeps everything in sync automatically.

Is the plugin free?

Yes. The core is free forever – receivables overview, traffic lights, filters, one payment reminder per invoice and mark as paid. Additional features are booked optionally via In-App Purchase.

Does this plugin add a "pay by invoice" payment method?

No. It manages receivables and dunning for orders that use an invoice payment method. You define which payment methods count as "invoice" in the configuration; if none is selected, Shopware's standard "Invoice" payment method is used.

Does dunning really run automatically?

Yes, with the Business plan. A daily scheduled task checks all open invoices and sends the level that is due – as long as automated dunning is enabled and the background worker is active. At most one letter per invoice is sent per day.

What about partial payments?

Partially paid invoices stay visible as open items but are never dunned automatically, because reminders and notices state the invoice amount. Please handle these cases manually.
