Run your business from one window.

Sollo is the back office for people who run a business alone or with a small team. Pick the apps you need: clients, projects, time, invoices, calendar and mail. A companion sorts and drafts, and asks before anything leaves. Built in Switzerland.

What does Studio Weber need?

Only the apps you need.

Switch an app on when you need it. Each part knows the others: a thread belongs to a client, a timer starts from a thread, and a timesheet comes from the hours.

  • Clients

    Companies, known by their mail domain, and the people in them. Projects, with the threads and hours of each.

    Clients waiting on you, longest wait first: 4 days for Helvetia Labs' question on line 12.
  • Time

    Several timers at once, kept running while the window is closed. Timesheets per client and period, exported as CSV.

    A week of hours per project, from Monday to Wednesday.
  • Calendar

    Your week, with invitations from Mail. Use Sollo’s calendar, or connect a CalDAV server.

    A week view with a workshop and a lunch with Marco.
  • Mail

    Optional. Any account over IMAP and SMTP, Proton Mail through Bridge. Your mail stays on your computer.

    The mail sidebar with Today, Inbox, Sent, Drafts and Archive.
  • ProjectsComing

    Budgets and tasks per client, with the hours from Time and the threads from Mail.

  • InvoicesComing

    Invoices from approved hours and fixed items, with the Swiss QR-bill and VAT by date. Sent from Mail.

  • AccountingComing

    Bookkeeping from your invoices and receipts, with the VAT return prepared each quarter, for you or your fiduciary.

  • CRMComing

    Leads, quotes and deals, from the first mail to the signed offer, with the next step for each.

One companion across all of it.

The same panel in Mail, Clients, Calendar and Time. It sorts, drafts and answers. It does not send, move or delete anything on its own.

  • Sorted on arrival

    New mail is sorted: what needs a reply, what is urgent, what is only a notification. The reason is shown beside it.

  • Drafts you approve

    Replies arrive as drafts in your own style. Change them, or send them with one key.

  • Ask in plain words

    Ctrl J opens a field. Ask for the hours on a project this month, or for the last quote you sent a client.

The Sollo panel answering when the new tax deadline is, with Accounting, and proposing a reminder for you to approve.

Skill packs: Swiss accounting, HR, Sales and Marketing.

Nothing is sent without you.

  • Mail stays on your computer

    Mail, drafts, summaries and rules are stored encrypted on your computer. They never reach our servers.

  • What leaves your computer

    Sorting runs on a local model. Drafts and questions go to Claude, and the panel shows what was sent each time. Any account can be set to local only.

  • Business data in Switzerland

    Clients, projects, hours and invoices are kept on our servers in Switzerland, encrypted at rest. A copy stays on your computer, so you can work offline.

  • Made in Switzerland
