As of November 12, 2026 · ProzessX Whether you have very little yet or already run everything: XOS closes digitalization gaps and system gaps. Where nothing is digital yet, XOS brings the software with it. Where programs run side by side, XOS is the layer where they come together. 37 modules, from quote to job costing, on one platform DACH Integrations for accounting, CRM and the workplace, including DATEV export and Lexware Office EU Your company data hosted in Europe, a dedicated database per customer €29.99 to start, per seat per month, chat with all models included ## Missing AI isn't the problem. The missing structure behind it is. Five issues we come across in almost every conversation, usually several at once. Next to each one: what XOS does about it. Problem 01: Shadow AI ### An approved AI that is better. Your staff has long been using AI, with private accounts, because the company doesn't provide one. Quotes, contracts and HR data end up there, and you never find out. Banning it doesn't help. A better tool does. - All common models in the company account - Access to your own company knowledge - Permissions and logging from day one Private accounts no longer needed Company account all models Company knowledge within reach Problem 02: Compliance and GDPR ### A check before every call. The data protection officer says no, and the whole initiative grinds to a halt. - EU processing is a switch per company, not fine print Message with attachment Personal data check Passed on to a model in the EU Problem 03: No centralization ### One place where it all comes together. The quote in the CRM, the receipt in accounting, the hours in the HR system, the project in the ticket system. The same data typed in three times, and the number you need is in none of them. - Existing systems are mirrored, not replaced - What lies in between finally has a home CRM mirrored Accounting mirrored HR mirrored XOS Platform one place Problem 04: Digitalization as a side project ### Up and running in days, not quarters. It's not a lack of will, but of time and expertise to carry out a digitalization project properly alongside day-to-day business. Set up, connect, work. - No implementation project and no consulting phase before the first benefit shows Set up Connect Work Problem 05: No time for the core business ### Recurring work runs on its own. Administration keeps growing, with reports, records and plans, while skilled workers are scarce. The work you started the company for comes last. - Sort the inbox - Generate reports - Reconcile data - At night without a prompt At night, without a prompt Inbox sorted Report is ready ## An assistant passes things along. A platform keeps hold of them. Pure AI assistants sit on top of programs you own. They read from them and write into them, but they have no place of their own. Anything that isn't in one of your systems doesn't come into being there either. Example: job costing ### The number you really need isn't in any single system. It comes from three. The contribution margin of an order needs the quoted price from the sales order, the material costs from the order items and the hours worked per order. XOS has a module for this: job costing is part of the system, not the result of a question. It's still there tomorrow, for everyone, with history. - Sales order quoted price - Order items material costs - Order hours hours worked Quoted price from the sales order Material costs from the order items Hours per order Contribution margin, for everyone, with history ## Included in every plan 01 ### Chat Chat with all models. 02 ### Communication Email, calendar and team chat. 03 ### Organization Tasks, projects, company files and tickets. 04 ### Knowledge and integration Knowledge base and connections. We run our own company on it. Every day. If something doesn't work, we notice before you do. XOS isn't software we build and sell to others. 1000+ In our own operations: over 1,000 AI sessions in our own organization, ongoing 100 % Built in-house: architecture and code are entirely in the hands of our team Direct Reachability: you talk to the founders, not to a ticket number ## Two areas where we're behind. We name them ourselves, because your purchasing team will ask anyway, and because an argument that collapses at the first follow-up question helps no one. 01 ### Security certifications The established providers are ISO 27001 certified. We're not yet, preparation is getting started. If a certificate is a requirement for you, for example due to group policy or audit obligations, we tell you before the project, not in the middle of it. 02 ### Integrations What counts for us is what German mid-sized companies need. Lexware Office is connected directly, and for DATEV, XOS generates the posting batch in DATEV format that your tax advisor imports. ## About the information on this page.
