From quote to paid order — in a single system.
Quotes become orders, orders become invoices, invoices become dunning notices. Tracked hours flow straight in. No tool bridge, no CSV import - a fit for trades & crafts, agencies, firms, and service providers.
- Quotes → orders → invoices → dunning notices
- Recurring invoices, fully automated
- GoBD-compliant with a gapless audit log
- DATEV export and interfaces connected
Four statuses, one continuous workflow
A quote becomes an order with one click. The order holds line items, hours, and materials. The finished order turns into the invoice — automatically, with your logo, IBAN, and tax number. Dunning levels run on deadlines you set freely.
- Quote with version history (the customer sees the approved version while you keep working internally)
- Order with line items, materials, and hours from work items
- Invoice with logo, IBAN, and VAT ID — as PDF and ZUGFeRD XML
- Dunning levels 1-4 with automatic escalation, configurable per customer
Recurring invoices without a single click
Service and maintenance contracts with monthly or annual flat rates: set them up once, and Stella creates and sends the invoice on the schedule you chose. An audit log shows what was created and when.
- Monthly, quarterly, semi-annually, annually, or on your own pattern
- Automatic dispatch by email using a saved PDF template
- The end of the contract term stops the recurrence automatically
- Audit log: which run created which invoice
GoBD-compliant with a gapless audit trail
Every step in the document flow is signed immutably with a user ID and timestamp. Reversals never replace the original — they offset it. Every access to a record stays traceable in the audit log.
- Cancellation via a reversal document (never by deletion), in the same number range
- Audit log with an immutable hash chain
- 10-year retention with file hash verification
- BWA and DATEV export in standard format
Open items and incoming payments at a glance
The open-items list per customer shows due dates at a glance. You post incoming payments manually or via bank import — with automatic matching to the invoice. Dunning levels run on their own.
- Open-items list per customer with due date and dunning level
- Incoming payment manually or via bank import (common CSV formats)
- Automatic matching by IBAN and payment reference
- Dunning levels within statutory limits
