Why TWT Business
Your team records its time per project and activity, and open hours become an invoice without anyone retyping them.
E-invoices arrive checked, go to the right person for approval and warn you when a supplier names a new bank account.
Photograph a receipt, and it is read on our own servers, ready to check and export.
Features
With TWT Business you run your projects, record hours, write invoices and e-invoices, check supplier invoices, keep your catalogue and turn paper into documents. All features clearly organised in one place.
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.
SalesInvoices
Draft to finalized, line items with per-line VAT and UN/ECE units, signature capture, QR code, duplicate and bulk actions.
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.
SalesPayment 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.
SalesReminders
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.
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.
ProjectsTime tracking
Record hours with the timer while you work, or by hand afterwards. The rate comes automatically from the activity or the project 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.
ProjectsProjects
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.
ProductsCatalog
Products and services in one item master with unit, price, VAT rate, SKU and sector.
ProductsStock
The quantity on hand per article with a minimum level and a storage location; what is below its level stands at the top.
ProductsStock movements
Every change as an entry with date, quantity and reason: goods received, sold from the invoice, returned, corrected, counted.
ProductsInventory count
Count, see the system quantity and the difference, complete — the stock is set to what was counted.
DocumentsScan
Five-step wizard: capture, adjust, process, review, export — a photographed receipt becomes a compliant e-invoice.
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.
DesignTemplates
Template library — duplicate, publish, set a default, mark a company-neutral standard.
DesignEmail 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.
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.
AdministrationNumbering
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.
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.

Requirements
TWT Business supports you with the requirements for invoices and receipts in Germany.
Since 2025 every business in Germany must be able to receive e-invoices. XRechnung and ZUGFeRD arrive in your inbox, checked against EN 16931.
From 2027 businesses with more than €800,000 turnover must send e-invoices, from 2028 every business. TWT Business writes XRechnung and ZUGFeRD today.
An issued invoice is numbered without gaps and locked, as the GoBD require. A correction is a cancellation invoice with reference to the original, never a deletion.
Invoices and receipts must be kept for eight years since 2025 (§ 14b UStG, § 147 AO). In TWT Business an issued invoice stays as it was issued, and a supplier invoice keeps the original file it arrived as.
TWT Business provides functions for proper invoices and records. The tax obligations of your business remain yours; when in doubt, ask your tax adviser.

TWT Business runs in your browser on every computer and tablet, and as a native app on Android.

The hours in detail, the receipt in the scanner, the supplier invoices and the rights of every single person.
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.

Photograph or upload an invoice. The receipt edge is detected automatically, layout and fields are read, units are inferred from a German keyword dictionary, and gross/net totals are reconciled against the printed total — then exported as ZUGFeRD or XRechnung.

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.
