What\'s included
What the catalog covers
The catalog is part of TWT Business. Everything that package includes, grouped the way you will find it again after you sign in.
Dashboard
Sales
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.
Purchasing
Incoming invoices
Receive, check and approve your suppliers’ invoices — a photograph, a PDF or an XRechnung, all in the same inbox. Being able to receive them has been obligatory since 2025; issuing them only from 2027.
Suppliers
Your creditors with their account mapping and every bank account they have ever invoiced from — what makes the changed-IBAN warning possible.
Projects
Time tracking
Record hours with the timer while you work, or by hand afterwards. The rate is resolved automatically from activity, project, customer, person or company — and then stays on the entry, so a later price rise does not re-price weeks already worked. Open hours become an invoice at the press of a button.
Projects
What is being worked on, with its customer, rate and budget. The analysis shows per project what has been earned, what has been billed and — the figure that matters — what has not. Internal projects with no customer belong here too: not every hour is sellable, but every hour wants to be seen.
Products
Catalog
Products and services in one item master with unit, price, VAT rate, SKU and sector.
Documents
Scan
Five-step wizard: capture, adjust, process, review, export — a photographed receipt becomes a compliant e-invoice.
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.
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.
Cancellation
Contract, end of term and cancellation in one place. Paid time stays usable to the end of the period, and the cancellation can be withdrawn until then.
Audit Logs
21 action types across 21 entity types, filterable and CSV-exportable, surviving deletion.
Time tracking and projects
Bill hours, not just items
Anyone selling their work by the hour usually keeps the hours in a spreadsheet — and that spreadsheet is then really where the invoice comes from. Here the two belong together: recorded time becomes an invoice line without anybody retyping anything.
- A timer for the work happening now, a typed entry for yesterday's
- The rate from activity, project, customer, person or company — and frozen after that
- Open hours into an invoice, grouped by project, activity or person — every hour exactly once
Incoming invoices
The obligation that already applies
Being able to receive e-invoices has been obligatory for every German business since January 2025 — issuing them only from 2027. It is also the side the market handles worst. Here every arriving invoice is read, checked and approved before anybody pays it.
- A photograph, a PDF and an XRechnung all reach the same inbox
- Checked against the official rule set, with a readable result
- A warning when a supplier suddenly names a different IBAN
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
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
What\'s included
It comes with TWT Business
