Customer chats all in one?

Hi CRM reddit, I have a small travel business and we run our advertising through facebook and whatsapp. The majority of our clients contact us back through Facebook Messenger and Whatsapp, I would like to know if you guys can recommend a service that integrates both of them in one. We need this service to be provided via the internet, mainly due to the fact that we reply to them via the Clippings Add-On from Mozilla Firefox for fast and precise responses. Just a quick breakdown of what’s needed: -Online/www-based CRM for chats -Integration for Facebook Messenger and Whatsapp -Can use online to apply Clippings Add-On from Mozilla Firefox -Hopefully not expensive as we run a small budget but we are willing to explore options available

Thanks for taking the time to read this post and providing your recommendations ahead of time.
