CREST SYSTEMSBuilt for the calls your team can't take.
CSflow is built first for trades and service businesses: HVAC, plumbing, electrical, and similar, where the phone is the pipeline and a missed call is a lost job. If your business misses calls, it applies to you too.
After hours
The 9 PM no-heat call gets answered, qualified, and booked for the morning instead of going to voicemail and then to a competitor.
While your team is on the job
Hands in a panel or under a sink, nobody has to choose between the customer in front of them and the one calling in.
When the line is already busy
The second caller gets a real conversation and a real appointment, not a busy signal or a hold queue.
What happens on every call
CSflow answers, tells the caller it is an AI and that the call is recorded, asks the questions your team needs answered, books qualified callers directly on your connected calendar, and texts the confirmation. Then it shows its work: every call comes back with the recording, the transcript, and everything it did, so you know exactly what happened without having been on it. The fastest way to judge it is to call the demo line yourself and watch the call stream live on this site.
