OSOI – One Source of Information for Teams
Connect site and office. Communicate, manage tasks, write notes, share documents, track time, and stay updated—all in one place.
Why teams work better with OSOI:
• Every project, every job site, all in your pocket – See what’s done, what’s not, and what’s urgent across all your jobs.
• It’s simple – If your team knows how to use WhatsApp, they’ll know how to use OSOI. No complex training needed.
• It’s not just another chat app – It’s built for getting work done. Chat like always, but now tasks, timesheets, and updates stay organized.
• Quick check-in on everyone – See who’s on-site, who’s off-site, and what they’re working on. Save yourself hours of phone calls.
• Can’t be deleted. Can’t get lost – Every message, task, and document stays in OSOI. No more missing info, ever.
• Find everything fast – No more digging through emails, WhatsApp, or five different apps. Finish jobs faster.
• Invite clients and contractors with one click and share updates in seconds – No more back-and-forth calls or emails.
• No signal? No problem – Works offline and syncs automatically later.
• Every working hour recorded, every day – No chasing the team for timesheets. Invoice your customers faster.

Introducing Activity Hub: Finally, an answer to “What have we actually done?”
Everything that has happened across your projects and your company now lives on one page. Who did what, where, and when, all in one place, in the order it happened. No asking around, no chasing people for updates, no piecing the week together from memory before a meeting. Open it and you know.
One time card for the whole day: Recording a day used to mean entering your attendance in one place and your project hours in another. Now it’s one card: start, breaks, end, and the work you did, all entered together, in one go.
Work types: Give every recorded hour a type that matches how your company actually works: Office, Business Trip, Workshop, or anything you define yourself. Your hours arrive already sorted, ready for whatever you need them for.
Minimum breaks: Choose your country’s statutory break rules for Germany, Austria, or Switzerland, or set up your own. Every day is checked against them, and OSOI either warns you or requires the missing break before the day can be saved. Nobody has to remember the rules anymore. OSOI takes care of it.
Overtime surcharges: Set the rules once: when overtime starts and what weekends and public holidays are worth. From then on, every day shows the hours that carry a surcharge, broken down by rate, in your tables and exports. Your bookkeeper is going to thank you for this one.
Expenses: Daily allowances, mileage, hotels, parking, and other expenses can now be recorded on the day they belong to, whether your people are on site, at a customer, or out in the field. Set up your expense types once with their amounts, mark which ones should be charged on to the customer, and rule-based expenses are automatically suggested as soon as the day qualifies.
Performance improvements: OSOI is quicker than ever.
And we’re already working on what’s next.
