The system has been very easy for us, as we are an online travel agency (OTA).
We have used it in many ways; from booking flights/hotels etc., through our OTA website itself! It's great having all this information at one place - makes life easier when you're working with clients who want everything organised before they go ahead & book their holiday or hotel stay!! I would definitely recommend using innatraack if looking into any sort off data management software solutions i think its really good value compared other options out there like zoho CRM.
