- calculate service costs based on different valuation elements,
- assign devices to the order
- determine whether the order was made, invoiced, paid,

- register customer’s devices (option can be enabled in Settings),
- add custom fields to describe devices,

In the app, you can define a list of your services and assign a default price to them. In the order, you can assign multiple services and use their default price or change it for the order. Of course, you don’t have to use prices and services in the order at all :)

The app allows you to back up the collected data so that it can easily be transferred to another device.

In Settings, you can customize app to the specifics of your business.

The app is able to work in dark mode.

The app will fulfill its role especially for people doing one-time or cyclical short-term orders, eg. in such professions as: electrician, physiotherapist, plumber, beautician, masseur, fitter, tile worker, tax counselor, legal counsel, service technician, locksmith, translator and many others.
Decide for yourself if it suits you.

After installing the app, full functionality is available at all times. The only restriction concerns the amount of data entered, i.e .:
- after entering the tenth order, you can enter one order for a given day in the order calendar,
- you can add another client if you have fewer than two,
- you can not restore data from a backup.

In order to fully use the app, you must purchase an annual subscription "Full version for a year” by going in the app to the Settings -> Purchases menu.

Payment will be charged to your Apple ID account at the confirmation of purchase. The subscription automatically renews unless it is canceled at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. You can manage and cancel your subscriptions by going to your App Store account settings after purchase.
