The 500-Conversations-a-Month Support Stack for a Bootstrapped SaaS

If you run a small SaaS and support is one of your three jobs, the customer support tools for a small SaaS team are not the ones a 40-agent contact centre buys. You need less software than the comparison pages suggest, and you need it wired together so that one person can take a long weekend without the queue collapsing.

This is a practical support stack for a startup with one to three people on support and roughly 500 conversations a month across chat, email and the occasional call. Each category names two or three real tools, says what they cost, and includes the pieces an AI agent like PepoChat does not replace. Prices are as of September 2026 from each vendor's pricing page; check their pricing page for current numbers before you commit.

What 500 support conversations a month actually looks like

Five hundred conversations a month is about 23 per working day. A conversation here means one customer thread from first message to resolution, whether it arrives in a chat widget, an email inbox or a booked call.

For a typical B2B SaaS at this size the mix is a large share of repeat questions (how do I invite a teammate, where is my invoice, do you integrate with X), a smaller share of account and billing changes, and a thin but expensive tail of real bugs and "is it down?" messages. The point of the stack below is to route each of those to the cheapest thing that can resolve it: the AI agent for repeat questions, the customer portal for billing changes, the status page for outages, and a human for the tail.

The number that matters is not conversations per month but human minutes per conversation. If the AI agent and self-service pages take the repeat questions, a solo founder handles the rest in two focused blocks a day. If they don't, 500 conversations is a full-time job.

Which customer support tools does a small SaaS actually need?

Eight categories, each with the free tier first, because at this size the free tier is usually enough for the first year.

Shared inbox and email

A shared inbox is a mailbox like support@yourdomain that several people can read, assign and reply from without forwarding emails to each other. It is the one tool you cannot skip, because email is where customers go when everything else fails, and where legal, billing and cancellation requests land.

Help Scout has a free plan with 5 users, 1 inbox and 1 Docs site, which is exactly the shape a three-person team needs. Its Standard plan is $25 per user per month billed monthly as of September 2026, with AI answers charged separately at $0.75 per resolution. Front starts at $25 per seat per month on annual billing with a 14-day trial, and suits teams whose "support" is really account management with lots of internal discussion. Missive's Starter plan is $14 per user per month for up to five users with a 30-day trial, and is the cheapest of the three that still feels like a team inbox rather than a Gmail label.

AI support agent with human handoff

An AI support agent is a chat widget that answers from your own documentation and hands the conversation to a person when it cannot. The handoff is the important half; a bot that never gives up is worse than no bot. The mechanics of a good escalation are covered in how human handoff should actually work.

PepoChat's free plan includes every feature and allows 500 AI replies per month and 10 knowledge sources. Be careful with that number, because a reply is not a conversation. A typical chat is two to four exchanges, so 500 replies covers somewhere between 125 and 250 conversations. If all 500 of your monthly conversations were in the widget, the free plan would cover a third to a half of them. When a free workspace hits the cap, new conversations are handed to the team inbox with a friendly message instead of failing, so the customer still gets an answer, just from a person. Pro removes the reply and source limits, supports up to five team members, and is month-to-month; the pricing page has the current figure.

The alternatives are the AI add-ons inside the inbox tools. Help Scout's AI Answers at $0.75 per resolution means 200 resolved chats a month costs $150, a useful comparison point between per-resolution and flat pricing. Whichever you choose, the setup is the same: point it at your docs and your marketing site, then review the first week of transcripts. The training guide walks through it; PepoChat's whole-website crawl counts as one source, which is why 10 sources goes further than it sounds.

Help centre and documentation

A help centre is the public, searchable set of articles that your customers and your AI agent both read. One good article resolves the same question for the AI, for search engines and for the customer who would rather not talk to anyone.

Help Scout's free plan includes one Docs site, so its free inbox brings the help centre with it. GitBook is free for one site with one user as of September 2026, with a $65 per site per month Premium tier on annual billing, and is the better choice if your docs are developer-facing. PepoChat also has a built-in Help Center; published articles are mirrored into the knowledge base automatically and removed when unpublished, which removes the "the bot is answering from an old article" problem.

Status page

A status page is a public page that says whether your service is up, with a subscribe button so customers hear about incidents from you rather than from a colleague. It is the cheapest way to stop the "is it just me?" wave after an outage, and the category most small teams skip until the first bad Tuesday.

Better Stack includes 10 monitors, one status page and 1,000 subscribers on its free tier, with checks as frequent as every 30 seconds. Instatus's free Starter plan gives 15 monitors, 200 subscribers and five team members, but a custom domain needs a paid plan. OpenStatus's free Hobby tier is one monitor and one status page with three components checked every 10 minutes, with paid plans from $30 a month, and it is open source if you would rather self-host. Pick the one whose alerts you will actually read.

Billing self-service

The single biggest reducer of support email in a subscription business is letting customers change their own billing. Stripe's customer portal is a hosted page where customers update payment methods and tax IDs, switch plans, cancel immediately or at period end, and download past invoices. It is enabled from the Stripe Dashboard with no code and is included with Stripe Billing, which as of September 2026 is priced pay-as-you-go at 0.7% of billing volume; a custom domain for the portal is $10 a month extra.

Put a "Manage billing" link in your app's settings and in every invoice email, and most card-update and invoice tickets disappear. For the ones that still arrive in chat, an AI agent can look up a plan or process a cancellation through a Stripe action; the Stripe subscriptions post explains how to do that without letting the bot near refunds. Paddle and Lemon Squeezy ship their own portals if you use a merchant of record; the principle is identical.

Scheduling

Some conversations are better as a 20-minute call: onboarding a new account, a churn-risk complaint, a prospect with an integration question. A scheduling link turns "when are you free?" into a self-service booking instead of five emails.

Cal.com is free for one user with unlimited event types, and its Teams plan is $12 per user per month on annual billing when you need round-robin between two or three people. Calendly's free plan allows a single event type, with Standard at $10 per seat per month. PepoChat can also book meetings directly from the chat through a PepoSmart calendar, with the agent checking real availability and the calendar handling timezones rather than the model; see how to let a chatbot book appointments.

Alerts in Slack or Discord

Nobody on a three-person team watches an inbox all day, so the things that matter should push into the chat tool you already have open. Slack's free plan gives 90 days of message history and up to 10 app integrations, enough for an alert channel; Pro is $8.75 per user per month billed monthly, or $7.25 on annual billing, as of September 2026. Discord suits developer-facing products whose customers are already there.

Wire three alerts and no more: a new escalated conversation from the AI agent, an email in the shared inbox that has waited longer than your target, and a status-page incident. PepoChat has prebuilt Slack and Discord actions for the first; Better Stack and Instatus both post incidents to Slack. Resist a "new conversation" alert for every chat; it trains the team to ignore the channel.

A simple feedback loop

A feedback loop is any structure that turns individual conversations into product decisions. At this size it is two things: a place customers can post and vote on requests, and a 30-minute weekly review of what support saw.

Canny is free for up to 25 tracked users (people who have left feedback), with Pro from $79 a month billed yearly. Tally is free for unlimited forms and submissions and works well for a "report a bug" form embedded in your app, with Pro at $24 a month for custom domains and no branding. A public GitHub Discussions board costs nothing for a developer product. PepoChat gives you a small loop for free too: visitors can leave a thumbs-up or thumbs-down at the end of a chat, and analytics show conversation volume, votes and auto-labelled topics in weekly buckets, which is exactly the input for the weekly review.

The support stack at three budgets

Figures are list prices from each vendor's pricing page as of September 2026, some billed monthly and some annually as noted above, so treat the totals as ballpark.

The free column is not a toy. It is a complete support operation with a queue, an AI first line, documentation, uptime reporting, self-service billing and booking. Its constraint is people, not software: it assumes one or two humans and a few hundred AI replies a month.

A weekly operating routine for a one-to-three person support team

Tools do not run support; routines do. This one fits around a founder's other work and keeps the stack healthy.

Daily, twice, 20 minutes each. Open the shared inbox and the AI agent's team inbox together. Reply to everything escalated or older than four hours. Snooze anything waiting on engineering to a specific day rather than leaving it open. Clear the alert channel to zero so tomorrow's alerts stand out.

Monday, 30 minutes: the review. Look at last week's conversation volume, thumbs-down votes and top auto-labelled topics. Any topic that appears three or more times becomes a help article, a product fix, or a suggested question in the widget. Read every transcript with a thumbs-down; there will not be many, and they are the most valuable ten minutes of the week.

Wednesday, 30 minutes: the knowledge base. Write or update the one or two articles the review produced, publish them, confirm they appear as knowledge sources, and ask the AI agent the original customer question to check it now answers correctly. URL sources are re-fetched weekly in PepoChat, but a new page has to be added once.

Friday, 15 minutes: the numbers. Note four figures in a spreadsheet: conversations, AI replies used, escalations, and median first human reply time. Four numbers show a trend, and the AI reply count tells you when the free cap is close.

Monthly, one hour: the stack. Check each tool's usage against its free-tier limit, prune alerts nobody acts on, and read the cancellation reasons Stripe collected in the portal. If a tool costs money and nobody opened it this month, cancel it.

What to upgrade first when volume doubles

Growth from 500 to 1,000 conversations a month rarely arrives evenly. One channel explodes, one tool hits a limit, and the founder notices when the Friday numbers jump. Upgrade in this order.

First, the AI agent's cap. Doubled conversations means doubled AI replies, and on a free plan the second half of the month spills into the team inbox. That is graceful, but it turns your cheapest channel into your most expensive one exactly when volume is highest. Moving to a flat plan is the only upgrade in this list that removes work instead of adding capacity. Measure what share of the new volume the agent actually takes in its first month rather than assuming a figure.

Second, a second human in the inbox. A co-founder taking a daily block or a part-time contractor; the shared inbox is what makes that possible without stepping on each other. Help Scout's free plan already allows 5 users, so the upgrade is a person, not a licence.

Third, the help centre. Not the tool, the content. Doubled volume means a longer tail of questions, and the Monday review will produce more articles than one Wednesday block can write. Spend a day on the top twenty and make each one a knowledge source.

Fourth, scheduling with round-robin. Once two people take calls, a Teams plan on Cal.com or Calendly ends the "who has this call?" confusion. This is also when PepoChat's meeting booking with round-robin host assignment pays off, because the agent can offer a frustrated customer a slot without either of you touching a calendar.

Last, everything else. Status page subscribers, Slack history and tracked users on the feedback board each hit a free limit eventually, but gently and one at a time. Wait for the limit, then pay for that one thing. Do not buy a full help desk suite yet; three people with a shared inbox and an AI agent are well inside what that handles.

What PepoChat does not replace in this stack

PepoChat is the AI support agent, the team inbox for chat, an optional help centre, and the meeting-booking and alert glue. It does not replace your email inbox, your status page, your billing portal or your feedback board, and the widget is web only, with no native Slack, WhatsApp or Messenger channel. It also has no published deflection statistics, so the share of your 500 conversations it absorbs is something you measure in your first month, not a number anyone can promise. The use cases page shows the common setups for SaaS teams.

What to do next

Set up the free column this week; it takes an afternoon and nothing in it needs a credit card. Start with the shared inbox and the status page because they protect you on a bad day, then install the chat widget and point the AI agent at your help centre. After one month, compare AI replies used against the 500-reply cap and escalations against your reply-time target, and let those two numbers decide whether the lean column is worth it. You can start a free PepoChat workspace in a few minutes, and every feature is on the free plan.
