Demos

Working systems, not screenshots.

These are demos we built in-house, not client work. They run on mock data, there is nothing to sign up for, and nothing you do here is saved. Open one, switch roles, and try to break it. The rules are the point.

  • Venue and equipment booking

    For venues and hire businesses that rent out rooms and kit by the hour.

    Roles

    • Customer
    • Staff
    • Manager

    The rule

    A slot that’s already held can’t be booked a second time.

  • Wholesale orders and stock

    For distributors and wholesalers who sell from stock, on credit.

    Roles

    • Sales rep
    • Warehouse
    • Accounts

    The rule

    An order can’t take more stock than is actually there.

  • Clinic appointments

    For clinics and practices booking patients across several doctors.

    Roles

    • Receptionist
    • Doctor
    • Admin

    The rule

    Nobody gets booked outside a doctor’s hours, or on top of another patient.

Why these exist.

Most software gets sold with a screenshot and a list of features, which tells you nothing about whether the thing actually holds together. These are the same mechanics we build for clients: who is allowed to do what, what happens when two people act at once, and what the system refuses to do. Easier to show than to describe.
