What the invoice doesn't show
Help Scout
Help Scout switched from per-seat to contact-based billing in 2024. A three-person team handling 500 customers/month saw projected costs jump from $66/mo to $266/mo — a 300%+ increase. The metric is 'famously tricky to forecast' and a viral moment can spike your bill overnight.
AI Answers costs $0.75 per resolution. At 1,000 AI resolutions/month, that's $750/mo on top of your base plan. For comparison, Gorgias charges ~$145/mo for 500 AI resolutions vs Help Scout's $375.
Add-ons inflate real cost by 30-40%: extra inboxes cost $10/mo each, extra Docs sites $20/mo each. Key integrations (Salesforce, Jira, HubSpot) require the Plus plan, nearly doubling per-contact cost.
The free tier removes data export and limits API access — creating GDPR concerns for European businesses and lock-in pressure to stay on paid plans even at low volume.
Zendesk
Zendesk's Advanced AI Copilot costs $50/agent/month and must be purchased for ALL agents — even if only a few use it. One G2 reviewer reported paying for 200 agents when only 10 actually used the AI features.
Since January 2026, Zendesk auto-bills overages on AI automated resolutions (ARs) with no pause or warning. Each resolution costs $1.50–$2.00. Baseline AR allocations per plan: Suite Team 5/agent/mo, Suite Pro 10/agent/mo, Suite Enterprise 15/agent/mo — with a hard cap of 10,000 ARs/year per account regardless of tier. A product bug or seasonal rush can exhaust your allocation and double your AI bill overnight.
A 10-person team on Suite Professional ($115/agent/mo) actually costs $55,800/year when you add Advanced AI, QA, and Workforce Management. Implementation fees run $6,000–$30,000, and renewal increases of 15–25% are common.
G2 and Trustpilot reviewers consistently report that Zendesk overpromised during sales and underdelivered on support. Users cite a steep learning curve and heavy reliance on dedicated admins.

eesel AI
$239–639/mo, no per-agent fees
