HubSpot Service Hub Alternatives: Keep the CRM (2026)
Last Updated
Published On
For a SaaS team outgrowing HubSpot Service Hub, the alternative usually isn't a new CRM but a new help desk: keep HubSpot as the CRM, replace Service Hub, and pick a tool that carries the CRM's account context into support. Plain is the agentic infrastructure for customer work. For B2B customer support teams, it's a help desk built around Slack, email and the accounts in your CRM: it syncs HubSpot companies and contacts onto every thread as accounts and account fields that can set the tier, the SLA and the routing, writes tickets and notes back to the HubSpot company, and treats Slack as a customer channel. Plain publishes this page for teams already on HubSpot CRM, and every HubSpot fact here comes from HubSpot's own pages as of November 2026.
What do B2B SaaS teams move to when they outgrow Service Hub?
The question is usually not whether to leave HubSpot, but whether Service Hub should stay the help desk: HubSpot can stay as the CRM while support moves to a tool that reads from it. 50 of 472 startups we spoke with that were replacing a tool were moving off HubSpot (June 2025 – October 2026).
Wanting every customer conversation in the same tool as your CRM is a reasonable instinct, and HubSpot is a good CRM; we use it as ours. It’s a weaker support tool, because support no longer happens mostly over email. It happens in Slack and every other channel your customers use. Service Hub is cheap to start because it's attached to the CRM, but as the team grows, seats and AI are billed at CRM prices, so price it at the team size you expect in a year, not the one you have today.
Whatever you move to has to handle the channels your customers already use. If that includes Slack, the help desk you pick has to treat Slack as a customer channel and put the HubSpot account on a Slack thread as readily as on an email.
According to Framer's case study, a 16-person global team runs enterprise support for 500,000+ monthly active users across Slack, Microsoft Teams and email, all on Plain. Plain's MCP server is now central to how Framer operates. Their team wired it into an AI-driven QA pipeline that reviews how tickets get handled, and a daily briefing that pulls from Plain, HubSpot, Gmail, and calendar into a single morning to-do list. If you want the wider field, including Zendesk, Intercom, Freshdesk and others, see Plain's round-up of customer support software.
What do you give up on the CRM side by leaving Service Hub?
You keep the CRM records. What changes is where the conversation lives and what HubSpot can report on automatically. Based on HubSpot's pages and Plain's docs as of November 2026, you give up:
Tickets as native HubSpot records by default. The conversation lives in Plain. HubSpot holds what a Plain workflow writes to it, through two actions, "Create ticket on company" and "Create note on company", with variables such as the thread link. A HubSpot report built on tickets sees only what you write back.
HubSpot's automatic cross-hub connection. According to HubSpot, records link up on their own once you run more than one hub. Support data that lives in Plain sits outside that connection.
HubSpot's customer agent and Service Hub's credits. Service Hub Professional comes with 3,000 HubSpot Credits a month, which HubSpot's customer agent draws on. Leave Service Hub and you leave both.
Phone and SMS. HubSpot's help desk page lists phone, SMS and WhatsApp among its channels. Plain's plans don't list phone or SMS as channels.
Real-time two-way sync. After the first run, Plain checks HubSpot about once an hour, and account fields flow one way, into Plain. Updates to existing people, contact removals, and company deletes and merges don't sync.
What you keep: the company and contact records, their properties on every thread, and a write-back path into HubSpot. For data that has to be live, such as plan status or usage from your own backend, Plain's customer cards read your systems directly, with a cache you set as short as 15 seconds, and nothing is copied into Plain.
How does Plain keep HubSpot account context on every support thread?
A list-scoped sync turns HubSpot companies into Plain accounts and their properties into account fields that show on every thread. A single-select account field can set the tier, and the tier carries SLAs and routing. Setup is three steps:
Build a list in HubSpot with only the companies you support, for example active customers. Plain watches that list for changes.
Connect in Plain. Go to Settings → Integrations → HubSpot → Connect, then Set up sync: pick the list and choose which company properties to bring across as account fields.
Enable the sync. The first run starts immediately. After that, Plain checks HubSpot for changes approximately once an hour.
Tier mapping creates one tier per option of a single-select account field and keeps assignments in sync as the value changes. If the property you segment on comes in as a single-select account field, the tier follows it, with response and resolution SLAs and routing by tier. The HubSpot integration and SLAs are on the Horizon and Frontier plans.
In HubSpot | In Plain after the move | How |
|---|---|---|
Company | Account | Hourly sync from a HubSpot list you choose |
Contact | Customer | New people sync; edits to existing people don't |
Company properties | Account fields on the account card in every thread | You pick which properties sync |
A single-select account field | Tier, with SLAs and routing | Tier mapping (SLAs on Horizon and Frontier) |
A new support conversation | Plain thread | Optional HubSpot ticket or note on the company via a workflow action |
Past Service Hub tickets | Threads with original timestamps | API import script |
CSAT ratings and custom ticket properties | Not imported | Rebuild if needed |
Company deletes and merges | Not synced | Clean up manually in Plain |
The same pattern works from your own data instead of HubSpot. Clerk built custom prioritization workflows across 4 pricing tiers with Plain's API, according to its case study: Clerk uses Plain's API to automatically map customers to the right tenant and tier, ensuring enterprise requests get prioritized — even when users belong to multiple apps with different plans. That is Clerk's own database and the API, not a HubSpot list. For the CRM and support data in one view, Sanity's case study describes its custom-built 360 dashboard. Built using Plain's open APIs, the dashboard pulls in support data alongside Salesforce, Linear, and other internal systems to give Sanity a unified intelligence layer across their stack.
How do Service Hub and Plain compare on price, seats, channels and AI?
The table lists prices from each vendor's own page as of November 2026. HubSpot's product page doesn't state a billing term; Plain's prices are billed annually. Sources are HubSpot's Service Hub page, its product and services catalog, and Plain pricing. HubSpot also sells a flexible seats-and-credits plan with different terms.
HubSpot Service Hub | Plain | |
|---|---|---|
Published price per seat | Starter from $20/month ($10 new-customer offer), Professional $100, Enterprise $150; billing term not stated | Foundation $45, Horizon $99 per user/month billed annually; Frontier custom |
Seats for people who reply | Service Seat for full Professional or Enterprise functionality; not available on Starter | Member seats: Foundation up to 5; Horizon minimum 3, up to 10; Frontier custom |
Seats for people who only read | View-Only Seat at no additional cost | Viewer seats, free and unlimited on every plan |
Free trial | 14 days | 7 days, no credit card |
Included AI credits per month | 500 / 3,000 / 5,000 HubSpot Credits | 1,000 / 2,500 / custom |
AI agent metering | HubSpot's customer agent, 50 credits per resolved text conversation | Customer Agent (formerly Ari), 100 credits per resolution |
Extra credits | $0.010 per credit, or $10 per 1,000-credit monthly pack; unused credits don't roll over | $10 per 1,000 credits; plan credits expire monthly, purchased top-ups roll over |
Channels named on the vendor's page | Email, live chat, phone, SMS, WhatsApp | Slack, email, in-app forms, live chat, Microsoft Teams (Horizon and up), Discord (Frontier) |
Slack | Native integration described as for team notifications | Slack channels as a customer channel: 25 on Foundation, unlimited on Horizon |
CRM | HubSpot Smart CRM built in | HubSpot, Salesforce and Attio sync on Horizon and Frontier |
A worked example: 5 people who reply plus 20 colleagues who only read. Service Hub Professional: 5 Service Seats × $100 = $500/month list, with the 20 readers on View-Only Seats at no additional cost. Plain Horizon, the plan with the HubSpot sync: 5 × $99 = $495/month billed annually, with the 20 readers on free viewer seats. Seat costs land close.
The differences are Slack as a customer channel, phone and SMS, and how AI is metered. HubSpot's customer agent uses 50 HubSpot Credits per resolved text conversation, from Professional's 3,000 a month. Plain's Customer Agent, its customer-facing AI agent, is on every plan and charged per resolution: 100 credits from the plan's monthly allowance, which is 2,500 on Horizon. Model either allowance on your own ticket counts, not on a headline.
The awkward part for Plain: Foundation, at $45/user/month billed annually, has no CRM integration. A team that wants the HubSpot sync starts on Horizon, minimum 3 seats, from $297/month, even if only one or two people reply.
How do you move Service Hub ticket history into Plain?
With a short script built on Plain's API, following Plain's Service Hub import guide. It is not a one-click importer. What comes across:
Contacts become customers.
Tickets become threads, and you choose which pipeline stages land as Done and which stay Todo.
Ticket emails and notes come across, with notes arriving as internal comments.
Ticket properties you choose become labels.
Original timestamps stay on every thread and message.
A link back to the original HubSpot ticket sits on each thread.
Not imported: CSAT ratings and custom properties on tickets. Four decisions to make before you run the script:
Map stages to Todo, Snoozed and Done. Plain has three status groups rather than custom stages, so keep any stage you report on as a label.
Use the HubSpot ticket ID as each thread's external reference. That makes the import safe to re-run.
Handle companies without a domain. Plain sets a customer's account from the email domain; a HubSpot company with no domain needs a custom account with its customers attached.
Decide how ticket owners map to users already invited to Plain.
Importing history triggers no SLAs, auto-responses or workflows, so nothing goes out to customers and no SLA clocks start on old tickets. Import less than you think. According to Tinybird's case study, the switch from JIRA to Plain took just two days, and the team migrated only what was still active, keeping their setup lean. That was a move from JIRA, not Service Hub, and not a typical timeline, but the lean approach transfers. Plain's 7-day free trial, no credit card required, is the place to test the script against a sandbox list. If scoping the script is the blocker, write to help@plain.com.
When should you stay on Service Hub, or look past Plain?
If phone or SMS support is core to your motion, stay. Service Hub lists phone, SMS and WhatsApp as channels; Plain's plans don't list phone or SMS.
If marketing, sales and service reporting has to live in one HubSpot report, stay. HubSpot connects data across hubs automatically, and that connection is HubSpot's to offer, not something a synced help desk reproduces.
If your team is small and works email and chat on HubSpot's free or Starter tools, the seat price is hard to beat. As of November 2026, Starter lists from $20 per seat per month, with a new-customer offer at $10.
If your customers live in shared Slack channels and your engineers need the account context on the thread, Plain, with the HubSpot sync on Horizon. Engineers and account owners read on free viewer seats.
If you need the HubSpot sync with fewer than 3 people replying, be honest about the maths. Horizon's 3-seat minimum means paying for seats you may not use, from $297/month.
If you keep HubSpot as your CRM and want to see your own HubSpot accounts on live Slack and email threads, book a demo.
Frequently asked questions about HubSpot Service Hub alternatives
Can you keep HubSpot CRM and use a different help desk?
Yes. As of November 2026, HubSpot sells the Smart CRM and Service Hub as separate products, and full Service Hub Professional or Enterprise functionality needs a Service Seat. Plain syncs HubSpot companies and contacts into Plain as accounts and customers on the Horizon and Frontier plans.
Does Plain write data back to HubSpot?
Account fields are a one-way sync from HubSpot into Plain. For the other direction, Plain workflows have two HubSpot actions: create a ticket on the customer's company and create a note on it, with variables such as the thread link.
Which Plain plan includes the HubSpot integration?
Horizon and Frontier. Horizon is $99 per user per month billed annually with a 3-seat minimum, so from $297/month. Foundation, at $45 per user per month billed annually, does not include CRM integrations.
Can you import HubSpot Service Hub tickets into Plain?
Yes, with a short script on Plain's API. Tickets become threads with their original timestamps, notes become internal comments, the properties you choose become labels, and each thread links back to the HubSpot ticket. CSAT ratings and custom ticket properties are not imported, and the import triggers no SLAs, auto-responses or workflows.
Does Service Hub or Plain support customer conversations in Slack?
