Comparison

Miross vs Trengo

Trengo is a European omnichannel inbox built around WhatsApp: the official WhatsApp Business API with free service conversations, live chat, email and social channels, voice as an add-on, a help centre and an AI agent. Its plans are flat, with many users included (10 on Boost) and a conversation allowance, so it suits larger teams better than small ones. For marketplace sellers it offers less: as of 27 September 2026 it lists an Amazon integration for order details, and no Mirakl marketplace. Miross is the other way round: Amazon and 60 Mirakl marketplaces connect directly, with WhatsApp from Growth. If WhatsApp and web chat carry most of your conversations and your team is large, Trengo fits; if marketplaces do, Miross does.

Miross covers more than support. The same workspace keeps the orders from every channel in one order book, makes shipping labels by your rules with your own carrier contracts, issues invoices with EU VAT, sets a price per marketplace from your margin rules and runs returns from the portal to the refund. Mike, its assistant, answers from your own orders, costs and cases and prepares the work for you to confirm.

How these numbers are built
  • Prices exclude VAT. “Per month” is a twelfth of the yearly price where the vendor sells yearly plans, otherwise the monthly price.
  • Every conversation gets at least one reply in the month, so it counts once for Miross and as one ticket or conversation elsewhere.
  • Connectors that bill per customer message are priced at 2 customer messages per marketplace conversation.
  • Dollars and pounds are converted at the European Central Bank reference rate of 25 September 2026: 1 € = 1.1403 $ = 0.86045 £.
  • Charges from third parties, such as Meta or Twilio for WhatsApp, aren’t included on either side.
  • Miross is priced at its list prices.

What Miross does beyond the inbox

Support is one part of Miross. The same workspace runs the rest of a seller’s back office, and every part works from the same orders.

  • Orders

    Orders from Amazon, your marketplaces and your own shop in one order book: what ships today, what is on hold and what already left.

  • Shipping labels

    Labels made automatically by your rules, with your own carrier contracts or Sendcloud. Tracking goes back to the marketplace.

  • Invoices with EU VAT

    An invoice for each order with the VAT it calls for: one-stop shop, home VAT, intra-community or local registration. Your numbering series and your template.

  • Prices per marketplace

    A price for each marketplace and country, worked out from your costs and your margin rules.

  • Returns

    A returns portal for your customers, the label from your carrier, reception by scanning with a phone and the refund.

  • Catalogue and purchasing

    Products with their costs, suppliers and purchase orders in one catalogue.

  • Warehouse

    A location for every product and pick routes for the day’s orders.

  • Mike

    The assistant that works inside Miross: ask in plain words how the shop is doing and he answers from your own orders, costs and cases, drafts replies and prepares the work.

When to choose Trengo instead

  • WhatsApp is your main channel and you want the official WhatsApp Business API, with templates and broadcasts.
  • Your team is large: Boost includes 10 users and Pro 20.
  • You want phone calls in the same inbox, which Trengo sells as an add-on.

Switching from Trengo to Miross

  1. Request an invite; we set up the workspace with you.
  2. Connect Amazon through Miross’s relay address and each Mirakl marketplace with its API key.
  3. Connect your mailbox. Miross links WhatsApp by QR code, like WhatsApp Web: a number on the official WhatsApp Business API, as Trengo uses, may need to leave the API before you can link it that way, so decide which number Miross should use.
  4. Keep Trengo for voice if you rely on it, and move your website chat to Miross’s widget: one script tag on your site.
  5. Export the conversations you need, then cancel at the end of your billing period.

Miross vs Trengo

Questions sellers ask

What does Trengo cost compared with Miross?

For 2 agents and 500 conversations a month: Miross €40.83, Trengo €299. For 5 agents and 2,000: Miross €165.83, Trengo €524. Per month excluding VAT, billed yearly where offered; the examples above show how each figure is built.

Does Trengo connect Amazon and Mirakl marketplaces?

Trengo’s integrations page lists Amazon, for order details and buyer information in the inbox, and no Mirakl marketplace as of 27 September 2026. Miross receives Amazon messages through a relay address and connects 60 Mirakl marketplaces with an API key.

How does Trengo count conversations?

A conversation is any reply to a customer message within a 7-day window; later messages start a new one. Boost includes 6,000 a year billed yearly, or 500 a month billed monthly, and more cost €15 per 100 (yearly) or €18 per 100 (monthly). Miross counts a case once per calendar month when a message is sent in it.

Why does Trengo cost more for a small team?

Its entry plan is priced for ten users and a set volume, so a two-person team pays for capacity it doesn’t use. Miross Starter includes 3 users and 500 conversations.

Is Miross only a helpdesk?

No. Support is one part of it. The same workspace keeps the orders from every channel in one order book, makes shipping labels by your rules with your own carrier contracts, issues invoices with EU VAT, sets prices per marketplace from your margin rules, and runs returns, the catalogue, purchasing and the warehouse. This page compares the support part.

What does Mike, Miross’s assistant, do?

Mike works inside Miross. Ask him in plain words what has to ship today, how much you earned yesterday or which products lose money, and he answers from your own orders, costs and cases. He drafts replies in the customer’s language and prepares the work that follows; a person confirms before anything is sent to a customer.

Does Miross make shipping labels and invoices for marketplace orders?

Yes. Orders from Amazon, your marketplaces and your own shop land in one order book. Your rules choose the carrier, on your own contracts or through Sendcloud, and the label is made by itself, with tracking sent back to the marketplace. Invoices carry the VAT each sale calls for: one-stop shop, home VAT, intra-community or local registration. Shipping is on every plan and invoicing from Growth.
