For most Shopify stores, WhatFlow is the better WhatsApp app than Chatarmin. WhatFlow is an official Meta Cloud API app with every feature on every plan, a team inbox with no seat fees at any size and native Shopify Flow automation, and it starts free with public prices. Chatarmin is a capable European suite with AI agents and ticketing. It's the right call mainly when you want those modules bundled together.
If you've seen WhatFlow filed under "unofficial WhatsApp tools for small shops", that's wrong. WhatFlow WhatsApp Business API runs on the official Meta Cloud API and is enterprise-ready: inbox assignment and filters, no seat fees at any team size, Shopify Flow automation, COD confirmation, catalog sharing and Shopify admin extensions. It's also the easiest start for a small store. Our linked-device Chat Automation app is a separate, older entry-level product.

How do the costs compare?
Chatarmin quotes by package. Ask for the subscription, messaging, onboarding and each module in writing, and keep the euro figures as euros instead of converting in your head.
WhatFlow's pricing is public on our pricing page:
- Free: every feature, first 100 messages.
- Plus, $9.99/month: 5,000 messages, then $0.004 each.
- Growth, $29/month: 20,000 messages, then $0.0025 each.
- Scale, $49.99/month: 40,000 messages.
Say a German fashion brand sends 12,000 messages a month (order updates, cart reminders, a weekly drop broadcast) and has six people answering. On WhatFlow that's Growth at $29, with all six in the inbox at no extra cost. Meta's per-message fees apply on any WhatsApp API platform. Our cost audit checklist is a good way to line up the two quotes.
Which fits Shopify workflows better?
WhatFlow plugs into Shopify Flow, so WhatsApp becomes one step in workflows you already run. A fulfilment event sends a shipping template. A reply mentioning "return" gets routed to the right agent. A COD Confirm tap tags the order. All on every plan.

Templates map Shopify order and checkout fields, so messages read naturally in any currency:
Hallo Jonas, your order #9182 (€74,90) has shipped. Track it here: [Track parcel]
How does a campaign reply become a support case?
This is where a lot of setups get messy. A customer answers your promo with "my last order never arrived." In WhatFlow, that message lands in the team inbox, gets assigned to support, and the agent replies with the order open:
Sorry about that, Jonas. I can see order #9182 is with DHL. I've asked them to check, and I'll update you here by tomorrow afternoon.
The person handling it doesn't need a seat licence, and the customer's opt-out preferences stay intact. Our GDPR consent checklist covers the consent side for EU stores.
When Chatarmin might still make sense
Choose Chatarmin if you want AI agents, a ticketing module and an omnichannel inbox from one European vendor in a single package. WhatFlow has no built-in AI agent; instead WhatFlow's MCP connector lets you bring Claude, ChatGPT or Cursor to draft replies a person approves.
The bottom line
WhatFlow gives Shopify stores everything they need on WhatsApp, on the official Meta Cloud API, with public pricing, every feature on every plan and no seat fees at any team size. Chatarmin is a solid suite if you want its bundle. For most stores, start with WhatFlow free and grow your plan with your sending.
