The Trengo alternative for AI that resolves, not just replies

Trengo vs Aftersales: what is the short answer?

Trengo is a Dutch omnichannel inbox built around WhatsApp, social and messaging, sold in team bundles: Boost is €299 a month for 10 users and Pro is €499 a month for 20 users on annual billing, each with a set number of conversations. Aftersales is an AI customer service platform priced per seat from $0, where the AI Agent costs $0.99 only when it resolves a conversation.

• Pick Trengo if WhatsApp campaigns, hospitality booking integrations or an AI voice agent are central, and you have 10 or more people on the inbox.
• Pick Aftersales if you want AI that takes guarded actions (Shopify orders, Stripe refunds, Salesforce), quality monitoring on every conversation, a free or small-team plan, or HIPAA support with a signed BAA (Enterprise).

Trengo's status: as of October 2026 Trengo still operates under its own name. Its about page says it was founded in Utrecht in 2017, raised a $36 million Series A in 2021 and works with 1,500+ customers. We found no acquisition, rename or shutdown.

Why do teams look for a Trengo alternative?

Most teams that look around are not unhappy with Trengo's inbox. They hit one of these limits.

• The entry price assumes a team. The smallest paid plan is €299 a month on annual billing (€349 monthly) for 10 users. A three-person team pays for seven users it does not use.
• Two meters run at once. You buy a conversation allowance (500 a month on Boost, 1,500 on Pro), then pay €15 per 100 extra conversations on annual billing, plus an AI surcharge of €0.25 per AI conversation (€0.30 monthly) deducted from a prepaid balance.
• AI actions sit on Pro. Trengo's plan table lists third-party AI actions as not supported on Boost and available via API on Pro and Enterprise.
• A conversation is a 7-day window. Trengo counts a new conversation when you reply outside a 7-day window, so long-running cases (warranty, B2B onboarding) can count more than once.
• Reporting and QA needs grow. Teams that want every conversation scored, not sampled, often add a separate QA tool.

What should you look for in a Trengo alternative?

• The channels your customers use. If most volume is WhatsApp, check the WhatsApp Business setup, templates and how message fees are passed on.
• How AI is billed. Per AI conversation, per resolution or bundled. Per resolution means you do not pay when the AI fails.
• What the AI can do, not just say. Look up an order, issue a refund, change a subscription, with limits you set.
• Handoff quality. When AI escalates, does the human see what it looked up and tried?
• Quality and insight. Can you see why volume spiked today, and score every conversation?
• Security paperwork. SOC 2 reports, SSO and SCIM, data residency, a BAA if you handle health data.
• Price at your real size. Model your seats, monthly conversations and AI share, not the headline plan.

When is Trengo still the better choice?

Trengo is the better pick in several cases, and we would tell you so on a call.

• WhatsApp is your main channel and you send campaigns. Trengo is an official WhatsApp Business partner, lists WhatsApp service conversations as free on its pricing page and sells broadcasting as an add-on.
• You run hotels, parks or holiday rentals. Trengo's integrations page lists Booking.com, Airbnb, Mews, Cloudbeds, Apaleo, VRBO and many regional booking platforms. Aftersales connects booking systems through its API or webhooks, so confirm specific connectors on a call.
• You want an AI that answers the phone. Trengo offers an AI Agent for voice. Aftersales supports phone for human agents, not an AI voice agent.
• You have a large team and moderate volume. Pro includes 20 users for €499 a month, which is hard to beat per head.
• AI coverage in many languages. Trengo says its AI works in 70+ languages; Aftersales covers 31.
• Sales and lead qualification. Trengo markets its AI Agent for qualifying leads, syncing a CRM and booking meetings. Aftersales is built for service.
• TikTok messaging. Trengo lists TikTok as a channel; Aftersales does not.

Is Aftersales cheaper than Trengo?

It depends on team size. Aftersales is usually cheaper for small teams; Trengo is usually cheaper at list price for teams of 10 or more with moderate volume. The examples below use list prices, annual billing and these assumptions.

What the totals leave out: Trengo's voice, broadcasting and channel message fees are extra, and its AI surcharge applies to AI conversations whether or not they end in a resolution. Aftersales charges only for resolved conversations, includes 20 free Lite seats on Growth, and needs no seat for Agent. If your AI share is low, the Aftersales bill falls; if it is high and you mostly answer questions rather than take actions, Trengo's surcharge model is cheaper.

What do Trengo teams get with Aftersales?

• Agent that acts within limits. Write a procedure in plain language (or import a macro) and Agent turns it into steps, each mapped to a connector with revocable permissions and spend limits. It escalates on sentiment, keywords, customer tier or legal language, and hands over with what it looked up and tried. Median resolution after 90 days is 71%; see the resolution rate guide.
• One Inbox for email, chat, WhatsApp, SMS, phone, social DMs and Slack Connect, with SLAs, views, side conversations in Slack and company metadata as filters.
• Insights that spot issues in real time and run Monitors on every conversation. Helio Energy raised quality scores by 14 points after Monitors replaced sampling.
• Copilot drafts replies that cite their sources, summarizes and translates in 31 languages.
• Ecommerce actions. Northwind Outdoors resolved 68% of post-purchase conversations in 30 days and cut cost per conversation by 41%. More on Aftersales for ecommerce.

How do you switch from Trengo to Aftersales?

1. List your channels and numbers. Note every email address, WhatsApp Business number, social account and phone number connected to Trengo, and who owns each with Meta or your telecom provider.
2. Export what you need. Pull contacts, labels and recent conversation history through Trengo's API documentation or ask Trengo support. Keep exports for your retention policy.
3. Move knowledge first. Bring help center articles and quick replies into Knowledge so Agent, Copilot and your help center use one source.
4. Rewrite your top flows as procedures. Take the 10 most common conversation types and describe each outcome, the data Agent needs and its limits.
5. Connect systems. Shopify, Stripe, Salesforce, Slack and Jira connect directly; booking, ERP or other tools connect through the Aftersales API or webhooks.
6. Plan the WhatsApp move. Agree a cutover date with both vendors so your WhatsApp Business number moves without a gap.
7. Run in parallel, then cut over. Start Agent on email and chat, review transcripts, then move WhatsApp and phone. On Growth and Scale the Aftersales team runs the migration with you; most teams finish in an afternoon.

Want AI without leaving your helpdesk? If you also run Zendesk, Salesforce Service Cloud or Freshdesk, Agent can run inside it with no seats and no migration, at $0.99 per resolution with a minimum monthly commitment.
