Best free customer service and help desk software for small business 2026
Six free customer service and help desk tools that are actually usable, not crippled trials. Compared by agent limits, channels, automation, and when you will outgrow each.
Direct answer
What is the best free customer service software for small business?
For most small teams the strongest permanent free tier is Zoho Desk Free — 3 agents on email ticketing with no time limit. If you need a live chat widget, HubSpot Service Hub Free adds chat and a shared inbox for up to 2 users. Freshdesk runs a 6-month free program for 2 agents, and osTicket is free forever if you can self-host. Every option below is a genuinely usable free plan, not a time-limited trial.
