Clients, offers, tasks, a timer and GoBD-compliant invoices in one interface. On your own you start free forever, with every area and no time limit.
In short
cashwerk is the business platform for freelancers and solo professionals: clients and contacts in the CRM, offers with an acceptance link, tasks on a board, time tracking with a timer and GoBD-compliant invoices built from exactly those hours. EU hosting and GDPR come with it. For 1 user cashwerk is free forever, including 2 GB of Drive and every area; e-invoicing, forms and dunning come with the Business plan.
Six steps from the first contact to the incoming payment, in one tool.
A contact or company with people, notes, appointments and every document.
Line items with your rate, acceptance or rejection through a public link, no login needed.
A board with columns from open to done, subtasks, comments and files per job.
Start, pause and stop on the desktop or the phone, with a category and a billable flag.
Tracked time becomes line items, numbered GoBD-compliant, as PDF/A and as an e-invoice if you need it.
Open items and partial payments in the list, reminders from the Starter plan, dunning levels on the Business plan.
The typical problems in your field – and how cashwerk solves them.
Four programmes for clients, tasks, hours and invoices, and each one wants maintaining
One system, one login: client, offer, task, hour and invoice hang together, with no export in between.
At the end of the month half the hours are missing
A timer on the desktop and the phone, later entry with breaks, and every hour hangs on a client and a task.
The invoice is built in Excel, and the business client asks for an e-invoice
An invoice from the tracked hours, GoBD-compliant with sequential numbers and PDF/A, as XRechnung or ZUGFeRD on the Business plan.
Payments come in late, and chasing them costs nerves
Open items and partial payments in the list, reminders from the Starter plan, dunning levels with fees and interest on the Business plan.
The functions that matter in your day-to-day.
Contacts and companies with history, appointments, tasks, offers and invoices.
Line items with your rate, acceptance through a public link, then the invoice in one click.
Columns named by you, subtasks, comments and files, included in every plan without a count limit.
Start, pause, stop, categories and a billable flag; hours turn into invoice line items.
GoBD-compliant with a number cycle, cancellation and credit note, output as PDF/A, tax rules configurable.
Time tracking, tasks, calendar, files and chat in the app, without a second login.
Offers are built from reusable services, show net, tax and total and go to the client as a PDF. Through a public link they accept or reject without an account, and the accepted offer becomes the invoice with all its line items.

Every job can be a project, with a budget, planned and tracked hours and a progress bar. The timer runs on the task, each hour carries a category and a billable flag, and it later becomes an invoice line item.
Incoming and partial payments hang on the invoice, and the list shows due date and status. If a payment does not arrive, dunning works with levels, fees and interest and shows the overdue total at a glance.
For your accountant, invoices and clients go to Lexware or sevDesk on the Business plan. The DATEV posting batch exports from Starter.

Trusted by leading companies







cashwerk bundles exactly that: contacts and companies in the CRM, offers with an acceptance link, tasks on a board, time tracking with a timer and GoBD-compliant invoices from the tracked hours. For 1 user that is free forever, including 2 GB of Drive, 2000 contacts and every area.
It includes CRM, offers, projects, tasks, time tracking, invoices, calendar, chat and Drive with 2 GB, plus 2000 contacts, 1 pipeline and 20 active deals. There are no AI credits here; those start on the Starter plan. A second user, e-invoicing, forms, dunning and the hand-off to Lexware or sevDesk need a paid plan.
Invoices run GoBD-compliant with sequential numbers, cancellations and credit notes and are output as PDF/A. XRechnung and ZUGFeRD, the formats for public buyers and many business clients, belong to the Business plan.
Yes. The timer runs on a task and a project, and every entry carries a category and a billable flag. When you write the invoice you take the hours over as line items, with the rate of the service in question. Hours that were already invoiced are locked, so nothing lands on a second invoice.
Yes. Tax rates and sales-tax regulations are configurable, among them the German small-business rule and the reverse charge. The rule belongs to the document.
You book another seat and everything stays where it is. Roles come as presets from viewer through editor to manager, plus possession scopes for access to your own or assigned records. You adjust the number of seats in the licence settings, and there is no data migration to do.
