Yes, if you decide to build end-to-end analytics by yourself. You will need to write technical specifications, agree on the data and metrics that will be displayed, and how they will be counted, think over the logic of integrations, etc.
You also need to be prepared for the fact that the analyst might not drive you the correct data the first time so that the system won't count it correctly. You will have to manually double-check whether all the data was driven correctly and whether the metrics were calculated correctly.
You won't have these issues with Ringostat end-to-end analytics. You connect everything on your own (we will give you a detailed setup manual, and our technical support specialists will promptly answer any of your questions). Moreover, the data is driven automatically.
You set up end-to-end analytics only once, and then the data is driven automatically. The only thing is that if you use advertising systems that Ringostat does not have any integration with (other than Google Ads, Facebook, Instagram, and Yandex.Direct), or if you have offline ads launched, you will have to upload the costs for these channels manually. But don't worry, it's easy and can be done in just a couple of clicks.
