Modern tools like Google Analytics allow to carefully analyse the data from CRM and prepare handy dashboards for the executive team and stakeholders.

Stylus is one of the largest retailers of electronics, home appliances, and accessories in Ukraine.
In order to calculate the workload of the call centre managers and competently build logistics, the online retailer needed to prepare a forecast for the next month, i.e. the daily number of transactions and calls received by the call centre, taking into account which parts of the country majority of the orders are coming from.
Based on the forecasts, the retailer expected to correctly allocate resources, marketing budgets, and make decisions about hiring new employees.
We analysed the existing methods of data analysis and settled on three models for forecasting time series:
To predict the time series, we used dedicated Python scripts, machine learning, various forecasting models, and Power BI for visualization.
Using forecasting models based on machine learning instead of the intuitive calculation methods allows to increase accuracy in:
To forecast each metric in the most accurate way, we took a data set from the CRM system and Google Analytics account for the past 2 years.
After studying the data, we made test forecasts to predict the number of sessions and transactions for the next three months and two years. This allowed tracking all the abnormal periods that increase the error in forecasting.
Trend analysis showed that a significant increase in sales for the retailer started in November 2018.
Weekly and annual seasonality charts allowed us to identify the periods of growth and fall in the number of transactions and predict the frequency of orders by month with an error of 10-15%.
To solve the retailer’s tasks, we decided to achieve more accurate indicators, since the everyday data was needed.
To achieve more accuracy, we refined forecasting models and created a dictionary with all the holidays, as well as periods of increased demand (Black Friday, Christmas, etc). This helped to reveal one more pattern: promo campaigns launched close to the period of high demand impact the dramatic trend changes. At the same time, this fact had almost no impact on the weekly and annual seasonality.
To distribute the warehouse workload, calculate the number of daily shipments and forecast the delivery of orders, we worked out a data set from the CRM and predicted the total number of orders, dividing them by country parts. We also created a dictionary of locations by region.
For some locations, the data was insufficient, so we combined them into a separate sample “The other parts of the country”.
To make the perception easy, we uploaded all data on the predicted transactions, calls and orders to Power Bi and presented it to the Stylus team in the form of interactive dashboards.
Such high accuracy indicators were achieved thanks to:
