What's included
What TWT Invoice covers
Everything TWT Invoice includes, grouped the way you will find it again after you sign in.
Dashboard
Sales
Quotations
Quotation, order confirmation and delivery note in one chain — each turns into the next with one click, each on its own number circle.
Invoices
Draft to finalized, line items with per-line VAT and UN/ECE units, signature capture, QR code, duplicate and bulk actions.
E-Invoice
Meet the legal requirements for e-invoicing in Germany with a single click: generate, convert, extract and validate ZUGFeRD and XRechnung against EN 16931.
Customers
Buyer master data including VAT ID, flowing straight into the e-invoice as BT-48.
Payment Terms
Agree your terms once and choose them on every document. Several discount levels — 3 % within 7 days, 2 % within 14, net 30 — with the deadlines and the amount to pay worked out for you.
Reminders
Up to three reminder stages with their own deadlines and fees. Default interest under § 288 BGB — nine points over the base rate against a business, five against a private person, day-exact and calculated separately across each interest period. Plus the 40-euro flat charge where it is due.
Documents
Documents by email
Your own address for supplier invoices. Hand it out, or forward your existing mailbox to it — what arrives is read, checked and approved like a document you uploaded. With a sender list, format and size limits, and a log that names the refused messages too, so no supplier is left sending into nothing.
Design
Templates
Template library — duplicate, publish, set a default, mark a company-neutral standard.
Invoice → Template
Upload an existing invoice PDF and get back an editable layout, plus detected customer, logo and company.
Designer
Drag-and-drop PDF editor with tables, totals, QR code, barcode, signature, data fields and undo/redo — without any programming knowledge.
Email templates
The covering note your invoice arrives with — in your words, not ours. A designer with formatting, colors, tables and placeholder chips, for eleven kinds of mail in German and English, with a signature and attachment rules. One template can serve several document types at once, individual customers can have their own, and each person can set a personal default. The preview shows what will be sent, the test mail sends it to you first, the history keeps every earlier state, and a misspelled placeholder is refused at save rather than printed at your customer. The send log records what actually went out — including what did not arrive.
Administration
Companies
Full legal profile: register data, tax numbers, banking, branding and § 19 UStG small-business mode.
User Management
Invitations, access levels, per-user permission overrides and ownership transfer.
Import data
Switch without retyping: customers, suppliers, the catalogue and your open items from a CSV file, as sevdesk, Lexware Office, Papierkram and Excel export them. Semicolons, umlauts and German numbers are recognised and the columns map themselves — with a dry run first and all-or-nothing on the way in.
Numbering
Four independent number circles — invoices, quotations, order confirmations, delivery notes — each with prefix, format, padding and a yearly or monthly reset, with a live preview.
Two-factor requirement
Whether a second factor stays voluntary, is required of everyone, or only of the access levels that can move money. Setting one up stays on each person’s own profile, and that page stays reachable so nobody is locked away from the requirement they have to meet.
Billing
Plan and single-module subscriptions paid by card — the payment itself switches the module on.
Audit Logs
21 action types across 21 entity types, filterable and CSV-exportable, surviving deletion.
E-Invoicing
Three formats generated, five understood
Generate ZUGFeRD EN 16931 (Comfort), XRechnung 3.0 or pure XRechnung XML — or convert an existing PDF. Upload an XRechnung XML or a ZUGFeRD/Factur-X PDF and get a report covering XSD schema, EN 16931 business rules, the German CIUS, PDF/A-3 conformance and XML embedding.
- Plain-language errors instead of raw validator output
- Extract XML from existing ZUGFeRD / Factur-X PDFs
- ERP export as JSON or 34-column CSV
PDF Designer
Design the document, bind the data
A full drag-and-drop layout editor — text, tables, totals, QR codes, barcodes, logos and signatures — without any programming knowledge. Bind any invoice field as a token that resolves live in the preview.
- Undo/redo, layers, align, snap and rulers
- Import and export template JSON
- Checks against EN 16931 core or the stricter German CIUS
Access Control
A real ACL, not role labels
61 permission keys organised as a module → component → action tree. Create custom roles, then layer per-user grants and denials on top — deny always wins, for every role including the owner.
- One key gates the API, the menu and the route
- Modules you cannot reach never ship their JavaScript
- Changes apply on the user's very next navigation
