Quotes & invoices

From quote to e-invoice in one database.

vemix brings quotes and invoices together in one module. You cost quotes from the price catalogue or freely, and invoices get a complete number range and are finalised. E-invoices follow EN16931 (ZUGFeRD/Factur-X), and invoices are fed directly from projects and tracked time.

Capabilities

Quotes, invoices and e-invoicing (ZUGFeRD) straight from project and time.

Quotes

Quotes with groups and line items from the price catalogue or freely costed. Salutation and address come from the CRM; the status runs from draft through offered and accepted to billed.

Invoices

Complete invoice numbering under § 14 UStG (German VAT Act), finalisation under GoBD (German principles for proper electronic bookkeeping): once finalised, the document is immutable. Cancellation and correction documents and the payment status are built in.

E-invoicing (ZUGFeRD)

Generate an EN16931 e-invoice at the click of a button: the structured XML is embedded in a PDF/A-3 (Factur-X/ZUGFeRD). Reverse charge and the small-business scheme are mapped correctly.

Invoice from project

An invoice is built from the fixed line items of accepted quotes plus the not-yet-billed time entries up to a cut-off date. Used entries are marked as billed, so nothing is billed twice.

Price catalogue

A lean price catalogue with article number, unit, net price and tax rate. Line items can be pre-filled from an article or freely overridden at any time.

Layout & master data

Mandatory details such as address, VAT ID and tax number safeguard finalisation. Adjust the logo, accent colour, font and header/footer text with a live preview. The EN16931 XML stays untouched.

Integrated

From first contact to paid invoice.

Quotes and invoices draw on customers from the CRM and pull effort and flat rates from projects as well as tracked hours from time tracking.

FAQ

Frequently asked questions

Does vemix produce real e-invoices?
Yes. vemix creates e-invoices to the European EN16931 standard in ZUGFeRD/Factur-X format: a structured XML embedded in a PDF/A-3. This meets the requirements for electronic invoicing in B2B business.
How does the module connect to projects and time tracking?
An invoice from a project combines the fixed line items of accepted quotes with the not-yet-billed, billable time entries up to a cut-off date. Hourly rates are resolved via a fallback chain, and used entries and quotes are marked as billed.
Are the invoices audit-proof?
Yes. Invoice numbers are assigned without gaps (§ 14 UStG), and finalisation under GoBD makes the document immutable in content. Corrections run through dedicated cancellation or correction documents; every change is recorded in the history.
Are the small-business scheme and reverse charge supported?
Yes. The small-business VAT exemption and the reverse-charge mechanism are mapped with the right notes and correct tax categories in the e-invoice.
