At a startup, the wrong support tool costs you twice: once in the subscription, and again when you migrate off it a year later. Most early-stage teams do not need the most capable product. They need one whose pricing unit matches how they grow, whose AI answers only what the docs support, and that does not lock their content in. This guide gives you the questions first, then the products whose pricing pages we read in September 2026. We sell one of them, so weigh our view of LayBuild accordingly.

Answer these before you look at vendors

  • Do you need a helpdesk, or a bot? If customers email you and you track issues as tickets with owners and deadlines, you need a helpdesk. If most questions come through your website or WhatsApp and are answered from docs, a bot plus a place to take over may be enough.
  • Which channels do customers actually use? Count last month's conversations by channel. Buying phone and Instagram support you will not use is common and expensive.
  • What is the pricing unit? Per seat, per resolution, per session, per credit, or flat. Write down how each one changes when your volume doubles.
  • How does the vendor define a resolution? Definitions vary a lot. Intercom counts a Fin outcome when the customer does not ask for more help after the answer; Help Scout counts one only if the customer does not escalate, search the knowledge base, ask more questions or say they need help. Same word, different bills.
  • Where does your knowledge live, and how does it get in? Help center articles, PDFs, a Notion workspace, a docs site? Check whether the tool syncs it, crawls it, or needs you to upload it by hand, and whether there are document limits.
  • What happens when the AI does not know? Ask for the exact behaviour: does it refuse, hand off, or guess? Then test it with ten questions your docs do not answer.
  • How does a human take over, and where does that land? A real-time alert in a dashboard, a ticket in your helpdesk, a webhook to your own system?
  • What does security review need? If a customer's procurement team will ask for SOC 2 or SSO, filter on that now. It is hard to add later.
  • Can you leave? Check whether you can export conversations and knowledge, and whether the product can be self-hosted if a customer demands it.

A quick way to compare cost

Suppose, as an illustration with made-up inputs, you get 1,000 conversations a month today and expect 4,000 in a year, and you think the AI could handle half. Under per-resolution pricing, your AI bill scales from about 500 to 2,000 billable resolutions. Under per-seat pricing, it scales with the number of people you hire. Under a flat plan with a cap, it stays fixed until you cross the cap. Run your own numbers through each vendor's unit before comparing headline prices.

Options we checked

All competitor details below come from each vendor's pricing page, checked September 2026. Prices change; click through.

Help Scout

Help Scout has a free plan for up to 5 users with one inbox and one Docs site. Paid plans are $25, $45 and $75 per user per month, with a monthly/annual toggle (16% off annual). Standard includes live chat, SMS, WhatsApp, Instagram and Messenger. AI Answers is an add-on at $0.75 per resolution, and the page mentions a 3-month trial of it. A good fit for an email-first team that wants a simple shared inbox and a help center.

Crisp

Crisp has a free plan with 2 seats and a chat widget, then flat per-workspace plans at $45, $95 and $295 a month with 4, 10 and 20+ seats. Paid plans include AI credits ($5, $25, $75), estimated by Crisp at around 90, 450 and 1,350 automated conversations. The omnichannel inbox (WhatsApp Business, Instagram, SMS and more) starts on Essentials. A good fit when you want one inbox across many messaging apps at a workspace price.

tawk.to

tawk.to gives away live chat, ticketing, a knowledge base and a contacts CRM. Branding removal is $29 a month, the AI Assist chatbot starts at $29 a month (with a free tier for low chat volume), and tawk.to hires out human chat agents at $1 per hour. The cheapest credible starting point if budget is the constraint.

Freshdesk

Freshdesk costs $19, $55 and $89 per agent per month billed annually. Freddy AI Agent includes the first 500 sessions, then $49 per 100 sessions. A ticketing helpdesk with AI priced by usage packs rather than resolutions.

Zendesk

Zendesk starts at US$19 per agent per month billed yearly for Support Team (email and ticketing), with Suite plans from US$55 adding messaging, live chat, telephony and AI agents. AI agents are billed per automated resolution, at a price you get from sales. The page also advertises a startup programme; read its terms on Zendesk's site. Choose it if you already know you will need a full helpdesk at scale.

Intercom

Intercom costs $29, $85 or $132 per seat per month billed annually, plus $0.99 per Fin outcome and pay-as-you-go messaging channels. Its Early Stage programme advertises up to 93% off and a year of Fin at no charge for eligible startups. Worth applying for if you qualify, but model what happens when the discount ends.

LayBuild

LayBuild is an AI agent for a web widget, WhatsApp and a REST API, priced flat in INR: Starter ₹1,499, Pro ₹3,999, Premium ₹9,999 per month (₹1,199, ₹3,199 and ₹7,999 billed annually), with 1,500, 8,000 and 20,000 conversations included and no per-resolution fee. Model token costs depend on the LLM provider configured. The bot answers only from your uploaded files, listed URLs and Q&A pairs. If retrieval finds nothing, or fewer than 25% of an answer's stemmed words appear in the sources, the customer gets a fixed "I do not have specific information about that" reply. That check is lexical, so it can block good paraphrases and miss wrong answers that reuse source words. You choose the LLM provider, and the source is open if you need to self-host.

What we do not have matters as much for a startup. No free plan or trial. No ticketing, no email, Slack, SMS or voice channel, and no Zendesk, HubSpot or Salesforce integration. No knowledge sync or crawling: you upload files or list URLs, up to 10 documents and 5 URLs on Starter. Retrieval is English-first. Learned answers are published automatically without human approval. Webhooks are logged but not retried. No SSO and no SOC 2, HIPAA, ISO 27001 or GDPR certification.

Matching the checklist to the options

If you need a helpdesk now, start with Help Scout or Freshdesk; Zendesk if you already expect a large team. If you mostly need a website chat with humans answering, tawk.to or Crisp's free plans cost nothing to try. If you want an AI agent grounded in documents, with a fixed monthly cost in INR and control over the model, LayBuild fits, and you can add a helpdesk alongside it when email volume justifies one.

Whatever you pick, test the "I don't know" path with real unanswerable questions before launch. It tells you more than any feature list.
