Invoices: create, send and record payments
The Invoices module (part of Accounting) manages drafts, sending and payment status for your outgoing invoices — including reusable templates, a product catalog, and DE/AT-compliant settings.
- You're signed in and your organization has "Invoices" (part of the Accounting module) activated.
- For sending: either quota on the Project Manager sender, or your own tested SMTP server under Settings → Email.

Filter invoices and keep an eye on the numbers
The All, Draft, Sent, Paid and Overdue tabs filter the list and show a count each. Above them sit four tiles with totals for Open, Overdue, Paid (including change vs. last month) and Draft. The search field also filters by client/invoice number; the download button next to it exports the currently filtered list as CSV.

Create a new invoice
"New Invoice" opens a blank form, or a pre-filled one via a template. A newly created invoice is always a draft without a fixed invoice number (shown as "pending"); the number, based on the configured format, is only finalized once you send it.

Import line items from time tracking
While editing an invoice, "Import from time tracking" pulls billable time entries from a project in as invoice line items. Invoices containing such items can no longer be duplicated afterwards — this prevents accidentally billing the same hours twice.

Send the invoice
The Send button is disabled as long as no client email is set. For a draft the action reads "Send", for an already-sent invoice "Resend". If the service date is missing, a warning (§ 11 UStG, German/Austrian VAT law) appears right in the edit form before you send.

Record a payment or mark it paid instantly
In the list, the checkmark icon in a row's actions marks an invoice as paid immediately. In the detail view, "Mark as paid" instead opens a form for amount, payment date, reference and note — this also supports partial payments. Individual payments can be reversed there with a reason; the entry stays visible as a reversed payment.

Use templates for recurring clients
The template icon (document icon) in the toolbar opens saved invoice templates with client data, tax rate, due days and default line items. "New invoice" on a template copies everything into a fresh draft; the star marks a template as default.

Maintain the product catalog
The shopping-bag icon opens the product catalog: reusable line items with name, description, category, unit price, unit and tax rate that you can pull into an invoice instead of retyping them every time.

Settings: Company, Email and Standards
The gear icon opens invoice settings with three sub-tabs. "Company" manages the logo (with a visibility toggle for the PDF), supplier data (address, VAT ID, tax number, IBAN/BIC, account holder) and the PDF print template (Classic/Modern/Minimal). "Email" sets the delivery mode — Project Manager sender with a monthly limit, or your own SMTP server (with a connection test) — plus the subject/body of the sending email. "Standards" sets the tax rate, due days, currency, language, invoice number format (e.g. RE-{JJJJ}-{NNNN}) and default notes for new invoices.
The invoice number is only final after sending
A draft shows no real number, only "pending". The system only assigns the sequential number per the configured format on first send — after that, it's fixed.
Duplicating doesn't work with imported time entries
Once an invoice contains line items imported from time tracking, "Duplicate" is locked. This is meant to prevent the same time entries from accidentally being billed twice.
Sending without a client email isn't possible
If the invoice has no client email address, the Send/Resend button is disabled (a tooltip explains why). Add the email in the form first.
Your own SMTP delivery needs testing first
When switching to "Own SMTP server", make sure to use "Test connection" before sending invoices through it for real — otherwise you'll only discover bad credentials when an actual send fails. The Project Manager sender also has a monthly cap on invoice emails.
