Worked example: 5 agents on 2 numbers. On Trengo Boost, you pay €299 a month billed annually for 10 users, even though you use 5, plus Meta message charges and any conversations above 6,000 a year. On Periskope Starter, 5 users plus 1 extra phone is 6 licenses: $150 a month on monthly billing or $90 on annual billing, with no message or conversation limits. Trengo becomes better value when you need close to 10 users and several channels; Periskope is lower cost for small WhatsApp-first teams.

Key differences between Trengo and Periskope

Trengo is an omnichannel customer service platform. WhatsApp is one channel next to email, live chat, social, SMS and voice, and it connects through the official WhatsApp Business API. Plans include a fixed number of users and conversations.

Periskope focuses only on WhatsApp. It links your existing numbers by QR code and brings every chat and group from every number into one inbox, with tickets, tasks, labels, custom properties and private notes.

Trengo suits support teams handling many channels. Periskope suits teams whose customers, partners or staff talk to them in WhatsApp groups and chats.

WhatsApp groups and the Business API

Groups on the official API are limited by Meta to numbers with an Official Business Account and 8 participants per group. Trengo’s pricing page does not list group management.

Trengo supports coexistence, so you can keep using the WhatsApp Business App on the same number, but its help centre says broadcast lists, group messages and some message types may not appear in the API inbox, and the app must be used at least once every 14 days.

Periskope syncs every group your number is part of and lets you assign, ticket and bulk-message groups like any other chat.

Integrations

Trengo lists CRM integrations with HubSpot, Salesforce, Pipedrive, Zoho CRM, MS Dynamics, ActiveCampaign and Copper, e-commerce integrations with Shopify, WooCommerce, Magento 2, Lightspeed and BigCommerce, and many hospitality tools such as Booking.com, Airbnb and Cloudbeds.

Periskope integrates natively with HubSpot, Zoho CRM, Freshdesk, Zoho Desk and Google Sheets, plus Zapier, REST APIs and webhooks.

AI features

Trengo’s HelpMate AI agent suggests and sends replies, and AI Journeys (in beta) automates multi-step flows. Conversations handled with AI carry a surcharge of €0.25 per conversation on yearly billing or €0.30 monthly.

Periskope’s AI agent answers from your FAQs and documents, calls your own APIs, creates tickets and escalates to people. Pro includes 5,000 AI credits per license per month, and the Periskope MCP server connects WhatsApp to Claude and ChatGPT.

When to choose Trengo instead

Choose Trengo if your team answers email, live chat, Instagram, Facebook and phone calls as well as WhatsApp, and wants one inbox for all of them.

Choose Trengo if you rely on its hospitality, travel or e-commerce integrations, such as Booking.com, Airbnb, Shopify or Lightspeed.

Choose Trengo if you need official API broadcasts and templates, or a dedicated success manager on Enterprise.

How to switch from Trengo to Periskope

2. Sign up for Periskope and scan the QR code from WhatsApp > Linked devices for each number.

3. Invite your team, set roles, and recreate labels, custom properties and assignment rules.

4. Connect HubSpot, Zoho CRM, Freshdesk, Google Sheets or Zapier.

5. Keep Trengo for email and other channels if you still need them, and move WhatsApp groups and chats to Periskope.
