Excellent LifeBusiness System
Це лише демо. Натискайте кнопки, щоб спробувати простий принцип роботи системи.
Повернули контроль
над щоденною роботою.
Після очищення робочого ПК Excellent Life втратили всі дані своєї старої, незручної російської 1С. Потрібен був новий початок — зі зрозумілим обліком і надійним зберіганням.
У жовтні 2026 року Kantsu Systems створили для косметологічної компанії систему під її робочі процеси: склад, продажі, клієнти та борги тепер пов’язані в одному місці.
Навели лад на складі
Допомогли з інвентаризацією. Додали облік у штуках і мілілітрах, щоб контролювати навіть продаж косметики на розлив.
Телефон став сканером
Камери телефонів працівників зчитують штрихкоди й додають товар до продажу. Компанія заощадила на закупівлі окремих сканерів.
Команда готова працювати
Провели навчання персоналу. Покупки клієнтів, часткові оплати й залишок боргу видно в системі. Продовжуємо її підтримувати.
Дані живуть у хмарі
База зберігається у хмарі та резервується щодня. Очищення чи заміна робочого ПК не видаляє бізнес-дані.

Alex Remodeling Knoxville
I developed a modern responsive website for a US remodeling company, including its service structure, interface, and clear customer journey to enquiry.
BUSINESS SYSTEM / USA
Northshore Operating System
For US construction company Northshore Homes, I reduced bureaucracy in everyday work. Requests, documents, and project management now come together in the company’s internal iPhone app.
- Time off from your phone
- Employees request time off directly in the app, with a clear path from request to approval.
- Invoices and OCR
- Document and receipt recognition reduces manual entry. Invoices move faster and are easier to check.
- Budgets, reports, and KPIs
- Reporting and metrics show how effectively budgets are being used across construction projects.
- AI that knows the company
- A dedicated corporate AI assistant works with Northshore’s rules and internal processes.
Staff handle everyday work from their phones, while management can see project progress and budget spending.
