5 questions to ask before buying Customer support & helpdesk software
How Customer support & helpdesk software is priced
Per agent per month by tier; AI resolutions and channels may be charged separately. SaaS Fit's advice is free for you: our fee comes from the vendor, and you never pay more than the vendor's own price.
Customer support & helpdesk software in the US: common questions
Do we need a HIPAA-compliant helpdesk?
Only if you handle protected health information; then you need a vendor that signs a Business Associate Agreement.
Do we need a helpdesk or is Gmail enough?
Once multiple people answer customers or you promise response times, a helpdesk pays for itself.
Can AI chatbots really reduce tickets?
Yes for repetitive questions, if your knowledge base is good. Complex issues still need people.
