What you keep
Keep the AI. MCP without Enterprise.
Cometly has an AI chat on Core and keeps its MCP for Enterprise. TrueROAS has chat, agent alerts and MCP on the Pro plan.
Example: asked which ads brought new customers last week, Trew AI checks 25 Shopify orders and answers Summer Sale #12 with 14 new customers ($1,960), UGC Hook v3 with 9 ($1,170) and Retargeting 7d with 2 ($240). Then an agent flags the ad set Broad Audience 3: Meta reports 6 sales, Shopify has 0, and it spent $420 this week.
- Trew AI chat on your data
- Agents that flag what needs action
- MCP for Claude, ChatGPT and Cursor (Pro)
Cometly lists MCP under Enterprise (pricing) and calls it public beta (MCP page, Oct 2026).
In their words
Cometly reviews well. It is built for SaaS now.
From a 2026 review and Cometly's own pages.
"Its just another tool with a bunch of complicated options, the pricing is also too high."
"Usage-based pricing. Built for B2B SaaS."
"We don't run a free trial because attribution requires CRM and ad-platform setup to be useful."
Cometly scores 3.8 on Trustpilot (93 reviews) and 4.8 on G2 (35 reviews), Oct 2026.

GermanyVery good app. I almost turned off an ad set that had a 4.5 ROAS because Meta tracked not all of the sales and had a Meta 1.5 ROAS.
League Outfitters
United StatesDefinitely worth the cost. Other attribution tools are at least 3X the cost, often with bloated features that you won't use. TrueROAS is the perfect balance for ecom brands.
Ziga Istenic
SloveniaA complete overview of all marketing channels we use, easy to implement and a great pricing structure. Honestly in my opinion the best analytics platform.
Jawliner USA
United StatesI have tested this tool for 2 months against another very expensive tracking tool, Hyros, and TrueROAS gives me the same 100% tracking.

How much does Cometly cost?
Cometly does not publish prices. Its two plans are priced on your monthly pageviews and quoted on a 30-minute call, billed monthly or yearly (yearly saves 20%), with no free trial. TrueROAS Pro is $299 a month for a store doing $100k a month, free under $10k a month, and every plan starts with a 14-day free trial.
Is Cometly built for Shopify stores?
Cometly now describes itself as "AI Marketing Attribution For B2B SaaS Companies", and its app is not available on the Shopify App Store. Shopify stores connect by pasting its pixel into the theme and setting up a Shopify webhook. TrueROAS is built for Shopify and WooCommerce stores and installs from the Shopify App Store.
Do I need onboarding?
For Cometly, yes: every customer starts with a 60-day onboarding program with a specialist. TrueROAS takes 3 minutes to set up, and your recent orders load in on day one.
Does TrueROAS have AI and MCP like Cometly?
Yes. Trew AI chat answers questions about your data, agents flag what needs your attention, and MCP comes with the Pro plan for Claude, ChatGPT or Cursor. Cometly's Agent chat is on its Core plan, and its MCP is an Enterprise feature in public beta.
Does TrueROAS send sales back to Meta and Google?
Yes. Real sales go to Meta and Google, so their bidding learns from real orders. It is included on Pro for one store, and an add-on ($49/mo) on Basic. If you also need LinkedIn, Reddit or Snapchat, Cometly sends to more ad platforms.
How soon will I see which ads work?
Cometly only tracks from the day its pixel is installed, and its help center says data takes 4 to 10 days to mature. TrueROAS loads your recent orders on day one.
Can I run both side by side?
Yes. TrueROAS reads the UTMs you already use, so nothing changes in your ads while you compare. If you then leave Cometly: its self-serve plans can be cancelled in billing settings and stay active until the period ends, with no refunds. Contract plans are cancelled through your Cometly rep.
