Setting up lead distribution in Bitrix24
I am completely satisfied with the collaboration. The performer did not just "take a look at something," but deeply understood the problem.
He found the real reason for the incorrect distribution of leads — not in the Bitrix robots, as we initially thought, but in the telephony integration (Binotel/API) and the mapping of sources. He explained the logic in detail, showed specific cases regarding leads and users, including non-obvious points with dismissed employees.
A separate plus for the approach:
- provides adequate recommendations on what and how to fix
- thinks like an analyst, not just a technical performer
