We collaborated with A2 Consulting on the implementation of the Qlik Sense business intelligence system to analyze the sales of our IT products, as well as to understand the most relevant sources of marketing activity for lead generation. By choosing A2 Consulting, we got not only an integrator with extensive experience, but also a business consultant with a professional approach and recommendations on business optimization, analytics in various contexts with full consolidation of our data sources. We started the project with unstructured data and did not understand what we would get at the output, as a result of the project and the synergy of the work of the integrator's project team and our IT team, we received a working full-featured application for comprehensive sales data analytics with the ability to build visual reports, track connections between data and make forecasts. We plan to further develop the system and recommend the company as a reliable IT integrator.
