Intro
GreenGas specializes in the distribution of liquefied gas in cylinders.
Currently, it operates in 11 distribution branches (nine owned and two affiliated), and collaborates with several partners. It supplies over 3,000 institutional customers (B2B) and around 70,000 households (B2C).
To optimize the costs of recurring sales processes for B2B and B2C customers and provide the most innovative solutions in the industry, GreenGas has decided to collaborate with iteo voice solutions for the implementation of voice solutions.


Business needs & goals
GreenGas has a customer base that regularly orders gas within specific time intervals. Prior to the introduction of the voice bot, contact with such customers was handled by the contact center staff.
The consultants would gather information about the assortment and quantity of gas cylinders ordered. The repetitive and linear processes were perfectly suited for automation through a voice bot, which allows for cost optimization and enables employees to focus on tasks that require more complex interactions with customers.
Functionality
Challenges & solutions
The GreenGas assortment consists of several dozen types of cylinders and gas variants. GreenGas customers often use colloquial language when placing orders, not specifying the catalog name of the product but using customary names instead.
The team had to train the bot to effectively process customer orders given in various ways regarding the requested assortment. An additional challenge addressed in the bot’s scenario was handling situations where the customer was unable to provide the assortment/quantity at the time of contact (requiring verification). The handling logic for such cases required initiating contact with the customer again.
Innovation
Preparing the solution, we used the proprietary tool Vosito, which is an AI-powered tool supported by machine learning. Its purpose is to improve the recognition of the speaker’s intentions.
Results
Outgoing contacts conducted by the voice bot effectively gather orders from GreenGas customers who regularly purchase the company’s products.
The optimization of the sales process costs and the ability to reallocate freed resources to more complex processes positively impact customer satisfaction while maintaining a high level of sales comparable to contacts made by contact center employees.
