DashboardDashboard
What needs doing today and the figures behind it, cut to your package: invoices, supplier invoices awaiting approval, hours and projects, or the books. Plus a guided first-run checklist.
SalesE-Invoice
E-invoices to the German standard: generate, convert, read and validate ZUGFeRD and XRechnung against EN 16931.
SalesCustomers
Buyer master data including VAT ID, flowing straight into the e-invoice as BT-48.
PurchasingIncoming 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.
PurchasingSuppliers
Your creditors with their account mapping and every bank account they have ever invoiced from — what makes the changed-IBAN warning possible.
AccountingCash book
Cash recorded the way cash behaves: written forward, never edited, and never below zero. With cash counts and the cash report, and with bookkeeping one-click posting into the journal.
DocumentsDocuments 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.
Cash registerCash register
The electronic till: sales with a receipt and QR code, cancellations as counter-transactions, a daily closing with the cash count and a DSFinV-K export. The certified cloud TSE is included.
AdministrationCompanies
Full legal profile: register data, tax numbers, banking, branding and § 19 UStG small-business mode.
AdministrationUser Management
Invitations, access levels, per-user permission overrides and ownership transfer.
AdministrationTax advisor
Who, besides your own people, may reach your data. A practice asks, you decide, and you can withdraw the access at any time — your own users are untouched.
AdministrationImport 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.
AdministrationTwo-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.
AdministrationBilling
Plan and single-module subscriptions paid by card — the payment itself switches the module on.
AdministrationTWT invoices
Every invoice from TWT in one place, across all modules, with the payment status per module and each invoice as a PDF.
AdministrationCancellation
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.
AdministrationAudit Logs
21 action types across 21 entity types, filterable and CSV-exportable, surviving deletion.
AdministrationSupport
Help from inside the product: ask a question, attach a screenshot, read the answer in the same thread. Each person sees only their own requests.
AdministrationNotifications
Where the product writes to: e-mail, Telegram or WhatsApp — one set for the company, and one of their own for each person. With a test message, so a wrong number is caught at once instead of staying silent.

Discover TWT One →For businesses
TWT Kasse provides extensive user and permission settings for businesses that need detailed control over their cash register processes, and receives your suppliers' e-invoices as well.
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.

More than 130 permission keys, organised as a module → component → action tree. Every member starts with the rights of their role; on top of it you grant or withhold single rights for exactly that person, and a withheld right always wins.
