A small B2B service business, an agency, a bookkeeping shop, a logistics operator, a boutique consultancy, usually lives out of one or two shared addresses: hello@, clients@, projects@, accounts@. The inbox is where prospects land, where current clients escalate, and where the next renewal is quietly won or lost. A plain Gmail label or Outlook folder stops scaling once two or three people need to see the same thread without stepping on each other.
We evaluated four of the shared-inbox platforms a 5-to-30-person B2B service team is most likely to pay for in 2026 (Hiver, Missive, Front, and Help Scout), using the current published plans and AI packaging on each vendor's own pricing page. The brief: a working team shares a single client-facing address, needs AI help drafting and triaging replies, and doesn't have a budget for enterprise onboarding fees. The criteria, the test method, and the per-tool marks are below.
How we tested
All four tools were evaluated between October 20 and October 23, 2026, by reading each vendor's current pricing, features, and documentation pages directly. We didn't run production inboxes inside each product; marks reflect what the published packaging promises, the real monthly bill for the target team, and widely reported product behavior from recent reviewer coverage. The target configuration is a 7-person B2B service team on one shared inbox, annual billing, with AI drafting turned on.
AI Reply Drafting & Triage Included on the Entry Tier
For each product, we opened the official pricing page and recorded which AI features (reply drafting, thread summarization, intent/sentiment tagging, auto-triage) are included at the cheapest paid plan without a separate meter or add-on seat charge. We did not count features marked 'coming soon' and did not count on-demand chatbots sold per resolution.
Shared-Inbox Fundamentals (Assignment, Collision, Notes)
We read each product's own feature documentation and compared shared-inbox fundamentals, ticket/conversation assignment, collision detection, internal comments on a thread, @-mentions, and private notes, against our required set for a client-facing B2B inbox, and marked any gap or any feature gated above the entry paid plan.
Channel Coverage on the Entry Paid Plan
We recorded, from each product's pricing page as of October 2026, which inbound channels (email, SMS, WhatsApp, Instagram, Messenger, live chat) are available on the cheapest paid plan, and whether multi-channel is gated to a higher tier or an add-on. Email-only on the entry tier scored lowest; three or more channels included scored highest.
Price Cliff Risk for a 5-to-15 Person Team
We modelled the monthly bill for the same 7-person team on each product's cheapest viable plan, then for the same team scaled to 11 and 15 seats, using each vendor's published annual rates. We flagged any seat cap or tier cliff that forces a whole-team upgrade (not just the new hire) and recorded the per-seat jump.
Real Monthly Cost for a 7-Seat Service Team (Annual Billing, AI On)
We calculated the full monthly cost for 7 seats, annual billing, with the AI drafting/agent features a service team would realistically turn on, including any per-seat AI add-on. Cheaper real totals scored higher; totals inflated by mandatory add-ons or metered AI the team would hit in normal operation scored lower.
We priced every tool on the same 7-seat service-firm setup: one shared client address, annual billing, AI drafting on. The full test battery and per-criterion marks are above; the notes below cover where the ranking turned.
Why Hiver leads for small B2B service teams
Hiver wins the dimension that decides this category for a small service firm: the real monthly bill once AI is actually turned on.
Growth includes the shared inbox and ticketing, AI Agents and AI Copilot, rule-based automations, pre-built analytics, basic integrations, and 24/7 support
, which means a 7-person team on annual billing pays $175 a month and the AI doesn’t add a line to the invoice. There’s no per-resolution meter and no $20-a-seat Copilot add-on. The product also sidesteps the biggest shared-inbox adoption problem for a Gmail-first team: Hiver in Gmail is a Chrome extension, not a new app, so onboarding is effectively just inviting the team.
The caveats are honest and narrow.
The Pro tier jumps to $55 a seat the moment a team needs SLAs, CSAT surveys, API access, or the customer portal
, which is a real $30-a-seat jump worth planning for. Seats come in bundles (2 to 5, then increments of 5) with a 2-seat minimum, and there’s no free forever plan on the current pricing page. For a small B2B service team that has stabilised somewhere between three and ten people, those are acceptable costs for the strongest AI-included value in the field. If your inbox work also starts upstream (personalising cold outreach, writing pre-call account research briefs, handling inbound chat), Hiver sits well next to those specialised tools without duplicating them.
When Missive is the right call instead
Missive is the pick when the client inbox isn’t just email and when the team wants collaboration primitives (shared drafts, internal discussion attached to the email itself, team spaces) that feel designed for teams rather than retrofitted onto a help desk. More than 6,500 companies run on Missive, and the product’s AI assistant is positioned as a context-aware helper that pulls from connected tools via MCP before it writes, rather than a sidebar bolt-on. For a service team that genuinely talks to clients across SMS and WhatsApp (logistics ops, agencies serving mobile-first SMBs, bookkeepers chasing documents) that channel coverage plus the collaboration model is the differentiator. The trade-offs: AI usage sits in the assistant layer rather than being bundled unlimited at the entry tier, and the more powerful capabilities (rules, integrations, API) concentrate on the higher-paid plans.
When Front is still worth paying for
Front is the pick when the shared-inbox fundamentals have to be first-class (complex SLAs, rules, handoffs across channels) and the team has the budget. The product is genuinely stronger than Hiver on depth. What rules it out as the default small-team recommendation is the AI bill.
For 10 seats, Front costs $250 a month on Starter or $650 on Professional when billed annually, that’s $3,000 or $7,800 for the year
, and that’s before Copilot.
The moment you hire an eleventh person, or need email and chat, you don’t move up a little; the whole team jumps to Professional at $65 per seat, a 160% increase per head
. If you’re already on 10-plus seats and need the muscle, Front is fine; for a 5-to-9 person service firm that just wants AI drafting on a client inbox, Hiver pays for itself quickly.
What didn’t make the cut
Help Scout is a credible fourth pick, especially for an email-first team that wants a built-in Docs knowledge base and an AI agent (Scout) that can resolve a meaningful share of routine requests end to end, Help Scout reports Scout resolves 73% of the requests it receives on average. The reasons it doesn’t win the small-service-team verdict: the agent-facing AI drafting lives inside the Copilot product rather than being the always-on default on every tier, and the customer-facing Scout agent is a separate billing layer that scales with success, not seats. For a service firm that wants a knowledge base as a self-service deflection layer on top of the client inbox (the same job you might otherwise ask an AI website chat widget to do), Help Scout is still worth the shortlist.
A note on scope: this ranking is about the shared inbox itself. If your team is a local service business whose client inbox is really a flood of review and reputation work, a shared inbox is the wrong tool, and an AI Google review reply tool is the right one. We mark all four of these products Recommended at their current pricing for a 5-to-30 person B2B service team; the ranking is about which one earns the money first.
Questions Readers Ask
Which AI shared inbox do you recommend for a small B2B service team?
We recommend Hiver for most small B2B service teams of 3 to 10 that already use Gmail or Outlook. AI drafting and an AI agent are included from the $25-a-seat Growth plan with no separate meter or per-seat add-on, so the real monthly bill for a 7-person team on annual billing is $175 and doesn't grow if the AI drafts more replies. Missive is the pick when the client inbox has to cover SMS, WhatsApp, or social at the same per-seat budget.
Why isn't Front ranked first when it's the best-reviewed shared inbox?
On the fundamentals, Front is the strongest product in the category: assignment, SLAs, multi-channel, analytics, and rules are all first-class. What drops it below Hiver for the small-team buyer is the AI add-on math: Professional at $65 a seat plus Copilot at $20 a seat is $85 a seat, against the $105 Enterprise tier that bundles Copilot, Smart QA, and Smart CSAT. For a 7-person team on annual Professional with Copilot, the real monthly bill is $595 against $175 on Hiver Growth with AI already included.
Does any of these tools let us keep working inside Gmail?
Hiver runs as a Chrome extension that layers shared inbox, assignment, AI drafting, and ticketing on top of a Gmail account, with no new app to learn. Hiver Omni and Missive are standalone apps that connect to Gmail or Outlook; your team moves into their app instead of Gmail. Front and Help Scout are both standalone apps. If 'we don't want to leave Gmail' is a hard constraint, Hiver in Gmail is the only one of the four that fits cleanly.
What should we budget for a 7-person service team on annual billing with AI drafting on?
On Hiver Growth, 7 seats × $25 = $175/month with AI Agents and AI Copilot already included. On Front Professional with Copilot, 7 × ($65 + $20) = $595/month, plus $0.05 per conversation if you turn on Autopilot. Missive and Help Scout bill AI as a separate layer on top of the seat (metered credits or per-resolution for the customer-facing agent), so budget the seat cost first and then layer AI usage on top. Those are the numbers to put in the budget before you pick.
