Omnichannel chatbots for mid-market sales conversions (2026)

The best omnichannel chatbot for a mid-sized sales team is the one that keeps a customer's history when they switch channels and doesn't charge you more for growing. Zendesk, Freshchat, Trengo, Gorgias and Cue all connect several channels to one inbox, but they differ sharply on pricing model, how AI is billed, and how well they suit sales conversations rather than support alone.

Key takeaways

• Zendesk covers the most ground, but a properly configured mid-market team usually lands between $165 and $265 per agent a month once AI and add-ons stack up.

• Freshchat connects WhatsApp, Instagram, Messenger, SMS, and email from one inbox starting at $19 a seat, though the bot still struggles once a question gets complicated.

• Trengo bills by conversation volume, so a marketing push that actually works can quietly inflate the bill.

• Gorgias is the deepest ecommerce fit, with a Shopping Assistant AI mode built specifically to convert browsers, but it's shaped around Shopify and bills AI resolutions on top of its ticket plans.

• Cue keeps unlimited seats on every plan from £249 a month and is built around WhatsApp, with phone, email, web chat and Messenger in the same inbox, for teams whose sales conversations already happen there.

A shopper browses your site on their phone during lunch, adds two items to a cart, then closes the tab. That evening they message your WhatsApp number asking if the item's still in stock. If your systems don't recognise it's the same person, someone starts that conversation from zero. The sale goes from a near-certainty to a coin flip.

Omnichannel isn't a buzzword for this problem. It's the fix. Connect the channels, carry the history, and a mid-sized team converts more of the traffic it's already paying for. Here's how five platforms actually do that job, and where each one falls short.

What should you judge an omnichannel chatbot on for conversion, not just support?

Every platform below, including Cue, gets measured against the same five things.

• Channel breadth: does it properly connect WhatsApp, web chat, social, email and calls, or bolt one channel awkwardly onto the others.

• Conversion features: cart recovery, proactive outreach, and product recommendations, not just answering "where's my order."

• History that follows the customer: a conversation that starts on WhatsApp should carry into web chat with the same history, not force the shopper to start over.

• Pricing that actually fits mid-market: real published numbers, not a headline rate that only small teams or enterprise accounts actually pay.

• CRM and journey integration: whether a completed sale or qualified lead lands in the CRM automatically, or someone updates a spreadsheet by hand.

Sales teams that get this right see it in the numbers. Research cited in Salesforce's guide to omnichannel commerce found that companies with a strong omnichannel strategy retain 89% of their customers. That number doesn't show up if the WhatsApp conversation and the web chat conversation don't know about each other.

How does Zendesk handle omnichannel for a mid-market team?

Zendesk bundles messaging, live chat, and a shared inbox across email, social, and web into its Suite plans, with basic AI agents included even at the entry Suite Team tier ($55/agent a month). Most mid-market teams actually land on Suite Professional at $115 a month. That's where skills-based routing and IVR show up, and running more than a couple of queues without them gets messy fast.

AI resolutions bill separately, somewhere between $1 and $2 each for mid-market deals, and Zendesk doesn't publish the exact rate. Add the Copilot add-on at $50/agent, and a realistically configured mid-market team lands closer to $165 to $265 per agent a month.

What it costs once it's configured

The sticker price is the easy part. Resolution overages have been auto-charged and uncapped since January 2026, so a good month for your AI agent directly raises the invoice. For a mid-sized team watching every line item, that unpredictability is the real cost behind "starting at $55."

What does Freshchat offer a growing team?

Freshchat covers the omnichannel list: web, WhatsApp, Instagram, Messenger, SMS, LINE, Google Business Messages, and email, all landing in one inbox, plus a free plan for up to 10 agents. Paid tiers are simpler than Zendesk's: Growth at $19/agent a month and Freddy AI at $49 per 100 sessions, Pro runs $49, Enterprise $79.

Where Freddy AI still trips up

Freddy AI Agent handles straightforward questions (order status, pricing, shipping) reasonably well. Anything more complicated still needs a human to step in. If WhatsApp is your main sales channel, ask Freshworks how WhatsApp message charges are billed, as they aren't shown on the pricing page. Freshchat is a stronger fit for a support-led team than one actively trying to convert.

Is Trengo built for conversion, or just support?

Support, mostly. Trengo's shared inbox pulls WhatsApp, email, live chat, and social into one place, and the collaboration features (tagging, auto-close, shared customer profiles) work well for a team of 10 to 20 fielding a high volume of inbound questions. Boost is €299 a month billed annually (€349 monthly) for 10 users and 500 conversations a month, and Pro is €499 billed annually (€599 monthly) for 20 users and 1,500 conversations (checked October 2026).

The pricing model that gets risky at scale

Conversations beyond your plan's allowance cost €15 to €18 per 100. Trengo isn't built primarily for outbound campaigns or proactive conversion pushes. It's a support-first inbox that happens to include WhatsApp. Run a successful WhatsApp marketing campaign and the extra inbound replies show up as overage charges, not just extra sales.

How does Gorgias drive ecommerce conversions?

Gorgias is the one platform here actually built around conversion. Its Shopping Assistant AI mode engages pre-purchase visitors with product recommendations and discount codes, not just post-purchase support, and it's wired deep into Shopify: order data, refunds, and discounts all inside the same conversation. Pricing is ticket-based rather than per agent, with helpdesk plans scaling from 50 to 5,000 tickets a month; see Gorgias's pricing page for current plan prices.

The ecommerce-only ceiling

The AI Agent is billed per resolved conversation, on top of the ticket plan, so model both lines at your real volume. The bigger issue for a lot of mid-sized companies: Gorgias's real strength is Shopify specifically. Off that platform, or outside ecommerce entirely, the integration depth that justifies the price mostly disappears.

How does Cue combine omnichannel messaging with conversion?

Cue links WhatsApp, phone, Messenger, web chat and email into one inbox, with chatbot flows and Cue's AI Agents answering and qualifying conversations on WhatsApp, email, web chat and Messenger, and the history staying on one contact record when a shopper switches channels. Cue's pricing starts at £249 a month (Connect, at 1,500 monthly active contacts), with unlimited seats on every plan, a structural difference from Zendesk and Freshchat charging per agent as a team grows. The chatbot builder and AI Agents (with 500 AI resolutions a month) start on Automate at £499 a month.

Calls sit in the same place. An inbound call lands in the inbox, matched to the contact by phone number, routed by keypad menu to the right team, and answered by a person; agents can also call a customer back from a WhatsApp or web chat conversation. Recordings and transcripts stay on the contact record. See how calls work in Cue.

Brights Hardware, a South African hardware retailer, saw a 244% increase in WhatsApp-based sales after rolling out a Cue chatbot for branch lookup, promotions, and rewards signups. More on that below, with the caveat it deserves.

Where Cue isn't the right fit

Cue doesn't do deep Shopify-specific actions, issuing a discount code or processing a refund mid-conversation, the way Gorgias does natively. A Shopify-first store leaning hard on that kind of store automation will get more out of Gorgias's integration. And a team running structured email ticketing with SLAs across many queues will find more purpose-built tooling in Zendesk's Suite Professional tier.

What should an omnichannel setup actually do to convert, not just support?

• Carry history across channels: a shopper who starts on WhatsApp and finishes on web chat shouldn't have to re-explain themselves.

• Act during the browse, not just after: a proactive nudge or recommendation converts more than a reactive FAQ bot ever will.

• Log the conversion automatically: a completed sale or qualified lead should land in the CRM without a manual step.

• Reach the channel your customer already prefers: customers move between channels depending on what they need, so the platform needs to follow them there, not force one channel.

• Scale without punishing growth: seats or conversation volume shouldn't become the reason automation costs more than it saves.

How do the five platforms compare at a glance?

How should a mid-sized company choose between these five?

The wider question of choosing a connected service platform, and how to test whether channels really share history, is worth settling before you shortlist.

Start with where conversions actually happen for you. If you're deep in Shopify and conversion means turning a browser into a buyer mid-chat, Gorgias's native store actions are hard to match anywhere else. If your team runs structured email and ticket support with SLAs across several queues, Zendesk's Suite Professional tier has real depth, just budget honestly for the $165-plus real cost rather than the $55 headline.

If you're a lean European support team consolidating channels into one shared inbox with fairly predictable volume, Trengo does that job well. And if WhatsApp, Messenger, web chat or the phone already carry most of your real sales conversations, and you want to add agents without the bill climbing per seat, that's the gap Cue is built to close.

Disclosure

Disclosure: This runs on cuedesk.com, and Cue is one of the five platforms in it. Every platform was judged against the same five criteria, drawn from public pricing pages, product documentation, and our own product knowledge, and Cue's limits got the same treatment as everyone else's. Competitor figures reflect July 2026 (Trengo, Freshchat and Gorgias rechecked October 2026) and will drift, so confirm current pricing directly with each vendor before you commit a budget. Cue's pricing and features were checked in October 2026.

What conversion result has a Cue customer actually seen?

Brights Hardware, a South African hardware and building-materials retailer with nine branches, needed one tool that could handle branch lookups, promotions, live agent chat, and rewards card signups without sending customers bouncing between different numbers and apps. They rolled out a Cue chatbot on WhatsApp to handle all four in a single conversation.

The result, per Brights Hardware's Cue case study: a 244% increase in WhatsApp-based sales. Retail and hardware carry their own buying pattern, repeat purchases, loyalty-card driven, and South Africa has particularly high WhatsApp usage, so treat this as a real, attributable result rather than a number every industry should expect to match.

Next steps

1. Map which channel actually carries your highest-value conversations today, WhatsApp, phone, web chat, email, or social, before comparing platforms.

2. Check the table above against your team size and real monthly volume, not just the advertised starting price.

3. Model AI and overage costs at your actual volume for every platform on your shortlist, since most bill AI or volume separately from the base plan.

4. Trial your shortlist with a real cross-channel scenario: start a conversation on one channel and confirm it carries into the next.
