Headline prices lie. Half these tools dangle a low sticker and recover it through a usage meter or a feature paywall the moment you do real volume. We reranked purely on the number that matters — the effective cost after the upsell — and named the one genuinely free option worth using and the two bait-and-switch pricing models to avoid.
On a value list, the decisive criterion is total cost after the upsell, not the sticker. We put effective cost at 35% and predictable, non-metered pricing at 20%, because a tool that starts at $10 and meters every ticket can finish dearer than one that charges a flat $14 — and a budget only holds if the bill is knowable in advance.

Zoho Desk
Cheapest serious option
It wins the value list outright: a genuinely free plan for up to three agents with real ticketing, then the lowest paid tiers of any serious platform — Standard $14, Professional $23, Enterprise $40 per agent. The pricing is flat per seat with no usage meter, so what you sign up for is what you pay. The pull is toward the wider Zoho suite, and integrations feel most fluid inside it, but on pure cost-after-the-upsell nothing here beats it.
A free tier for up to two users and a $7/seat Starter make HubSpot the cheapest honest entry point, and if you already run HubSpot CRM the tickets sit on the same contact record for free. The catch is the cliff: the jump from Starter to Professional is $90/seat, one of the steepest in the category, so the cheap tiers are cheap precisely until you need routing, SLAs or automation. Excellent value at the bottom, expensive the moment you climb.
Growth at $19/agent is a fair cheap tier, but Freshdesk lands here because its 'free' is the bait: the old open-ended ten-agent free plan is gone, replaced by a one-to-two-agent, time-limited program, and the features most teams need — automations, SLA, round-robin, CSAT — sit behind Pro at $55. Read it as a $19 tool, not a free one, and know the real jump comes when you outgrow Growth.
Help Scout is the nicest tool to use at this price and its flat $25 Standard seat is honest, predictable per-seat pricing. It ranks below the cheapest three on pure cost: the free plan caps at 100 contacts a month — fine for a trial, not a real queue — and AI Answers meters at $0.75 per resolution on top. If you value a clean, email-style inbox over squeezing the last dollar, it earns the premium; if the budget is the whole point, it is a step up in spend.
The $10 Starter looks like the cheapest thing here until you read how it bills: per ticket, with overages around $0.36–$0.40 each once you pass the cap, and AI Agent interactions at $0.90–$1.00 that also count as tickets. For an e-commerce store that is the point — it is a strong Shopify support tool — but as a budget pick it is a classic bait-and-switch: the low sticker recovers itself the first busy month. Great tool, wrong list for a fixed budget.
Intercom is a superb product and the wrong one to shop for on price. Essential looks like $29/seat, then Fin AI resolutions bill at $0.99 each, so the cost tracks your volume in a way that is impossible to budget against. There is no meaningful free tier and the whole model assumes you will pay for outcomes. If your criterion is 'cheapest', this is precisely the trap: brilliant capability, the least predictable bill on the list.
If cheapest is the brief, Zoho Desk wins on the only honest measure — cost after the upsell: a real free plan for three agents, the lowest paid tiers here, and flat per-seat pricing with no meter to surprise you. HubSpot's free-and-$7-Starter is the next best value if you already run its CRM, provided you never need the $90 Professional tier. Read Freshdesk as a $19 tool, not a free one. And steer clear of Gorgias and Intercom if the budget is fixed: their metered models can start cheapest and finish most expensive.
Questions we get
What is the genuinely cheapest serious help desk?
Zoho Desk. It is the only tool here with a free plan that is free forever — up to three agents with real ticketing — and its paid tiers are the lowest of any serious platform: Standard at $14, Professional at $23 and Enterprise at $40 per agent per month on annual billing (verified July 2026). The pricing is flat per seat with no usage meter, so the bill you sign up for is the bill you pay. If cost is the deciding factor and you want capability that survives past a trial, this is the pick.
Is Freshdesk still free?
Not the way it used to be. The old open-ended free plan for up to ten agents is gone; the current Free program covers only one to two agents and for a limited window rather than forever. Worse for a budget buyer, the features most teams consider essential — automations, SLA management, round-robin routing, CSAT — are gated behind the Pro plan at $55/agent/month. The honest cheap tier is Growth at $19; treat the 'free' as a trial, not a plan.
What's the bait-and-switch to watch for on cheap help desks?
Usage meters hiding behind a low headline price. Gorgias starts at $10/month but bills per ticket, with overages around $0.36–$0.40 each and AI Agent interactions at $0.90–$1.00 apiece. Intercom's Essential looks like $29/seat until you add $0.99 per Fin AI resolution. Even Help Scout meters AI Answers at $0.75 per resolution on top of the seat. A metered tool can start cheapest and finish most expensive; for a predictable budget, weight flat per-seat pricing over the lowest entry price.
What's the cheapest free option that's actually usable?
Zoho Desk's free plan for up to three agents is the most usable free tier here — real ticketing with no time limit. HubSpot Service Hub's free tier is a close second, covering up to two users with a shared inbox and basic ticketing, and it is the better choice if you already run HubSpot CRM. Help Scout's free plan works too but caps you at 100 contacts a month, which a real support queue blows through fast. Match the free tier's limit to your actual volume before you rely on it.
