Every feature, including the Mei AI assistant, is in every plan. - AI that answers from your data: Ask Mei for a report, a draft invoice or a tax pack. It reads only what you are allowed to see. - Running within 24 hours: We set it up with you on our cloud, or install it on your own server. Either way your business runs on it within a day. - You own your data: Export it any time. You are never locked out of your own data. - Try it before you talk to us: A private demo with sample data, ready in seconds. ## Modules Use all of them or only the ones you need; they share one set of people, clients and permissions. - People & HR: From joining day to the last working day, in one place. (Employee records, Confidential documents, Attendance, Shifts & holidays, Leave management) - Projects & Tasks: Know who is doing what, and how long it really takes.

Ask a question the way you would ask a colleague and get the answer, with the figures behind it. - Reports on demand: Monthly attendance, profit and loss, receivables, tax summary, project status, timesheet hours. Download any answer as CSV or print it as a PDF. - Acts only with your OK: Mei can propose a new client or a draft invoice. You see a card, edit anything, and confirm. Nothing is created until you do, and invoices stay drafts. - A tax pack with only what is needed: One ZIP for the period: the tax reports as CSV plus the invoice PDFs and expense receipts those reports are made of. Nothing extra. - You choose who gets it: Give Mei to everyone, or only to chosen people, teams and departments. Anyone else is told to contact their administrator. - See who used it and how much: Questions, people and tokens for any period, by person and by model, so there are no surprises on the provider's bill. - It sees only what you can see: Mei reads your data as you, through the same permissions as the app. If your role cannot open finance, neither can Mei for you. - Your own AI account: Connect your own key from OpenAI, Claude, Gemini or OpenRouter. AI usage is billed to you by the provider, at their price, with no mark-up. - Nothing changes by surprise: Every change goes through a confirmation you can edit, and is made as you, with the same checks as doing it by hand. ## Pricing One flat price by company size, never per user.
