CRM in a spreadsheet, invoices with the accountant? Customers, projects, time and invoices live in one system, reachable via API, webhooks, MCP and n8n.
In short
cashwerk is the business platform for software teams, SaaS companies and IT service providers: CRM with pipeline, client projects, time tracking and GoBD-compliant invoices in one data model instead of five tools. Everything your team does in the UI is also reachable via the REST API, by webhook, from your AI client via MCP or from n8n. EU hosting, GDPR, GoBD – and 1 user free forever.
Customers, projects, time and invoices live in one system, reachable via API, webhooks, MCP and n8n.
The REST API lives under /api/v1. Keys and OAuth2 clients belong to the workspace, scopes limit every access, and the docs come from the OpenAPI specification.
You’ll find the documentation at /docs/api. There are no SDKs or sandbox workspaces yet – the API is deliberately lean and typed.
Learn moreEnter one URL, sign in via OAuth. Claude, ChatGPT, Cursor and VS Code query customers, deals, projects and invoices and create what you need.
MCP server and n8n node are generated from the same OpenAPI specification as the REST API. Change an endpoint and all three change.
Learn moreInvoices come from the project, tracked hours or line items. Subscriptions become recurring invoices, milestones an invoice chain, and everything ends up in Lexware or sevDesk.
The typical time sinks in your industry, and what gets taken off your plate.
The CRM is a spreadsheet nobody maintains – and the pipeline lives in Slack threads
Put deals on a board with stage, value and owner. Every change can fire a webhook.
Invoices are created in the accountant’s tool, subscriptions are re-issued by hand
Create invoices from a project or line items. Subscriptions run as recurring invoices, e-invoicing from the Starter plan.
Five tools, five logins and a Zapier construct that breaks at night
Replace the Zapier construct with one data model behind the REST API, webhooks and the n8n node.
The team wants to query business data in its AI client, not dig through exports
Query your business data right in your AI client. Claude, ChatGPT, Cursor or VS Code work with your permissions.
The usual construct of single tools – and what of it collapses into cashwerk.
One system, one login, one data model. 1 user free forever, then from 14 € per user and month on the Starter plan.
Try it with your own data.
From the deal to the booked invoice – one system, with an endpoint at every step.
Contacts, companies and deals on a board with stages, value and probability.
The won deal becomes a client project with a kanban board and a team.
A timer per task, flagged billable, with an hourly rate per service.
From time or line items: GoBD-compliant, as an e-invoice, as a recurring invoice for subscriptions.
Invoices go to Lexware or sevDesk; your accountant gets clean documents.
Every step is an endpoint, a webhook event or a tool for your AI client.
Less admin, more time for your clients.
API keys per workspace, docs via Swagger, rate limits per plan. Included in every plan.
Outbound events from a catalogue that is checked against the code. From Starter.
Any MCP-capable client connects via OAuth, listed in the Claude connector directory.
The n8n node on npm is generated from the same specification as the API.
GoBD-compliant as PDF/A, e-invoices as XRechnung or ZUGFeRD, subscriptions as recurring invoices.
Role presets; the same permissions apply in the app, via API and over MCP.
Pipeline, project cockpit and dashboard – the same data your API returns.
Trusted by leading companies
Not yet. There is the documented REST API with API keys and OAuth2, webhooks, the MCP server and the n8n node on npm – all generated from the same OpenAPI specification. A public developer portal with guides, sandbox workspaces and SDKs are on the list but are not part of the product today. For testing, use a free workspace.
Nothing extra. API keys are available in every plan; the number of requests per minute depends on your plan: 10 on the free plan, 100 on Starter, 1000 on Business. Webhooks are available from the Starter plan, your own OAuth2 clients on the Enterprise plan.
Enter the MCP server URL in your client and sign in via OAuth. The client then works with exactly your user’s permissions – reading without confirmation, creating and changing only with approval. You can revoke the connection at any time in the settings.
Yes. A recurring invoice defines rhythm, line items and recipient once and generates the invoices automatically – booked and sent from your own mailbox if you like. For long projects there are progress invoices as a chain up to the final invoice.
Through the hand-off to Lexware or sevDesk on the Business plan, where invoices and customers arrive structured. The DATEV posting batch exports from the Starter plan. Every invoice is also stored as PDF/A in Drive and can be exported as CSV.
No. Every area works on its own; a team can start with CRM, projects and time tracking and add invoicing later. All areas are included in every plan – the differences are limits and extras such as e-invoicing or forms.
