"Recommended" is our own pick, and we are not a neutral party: MerchantFlow is our product. Every competitor cell is drawn from that vendor's published pricing page and Shopify App Store listing on the dates below. Blended P&L means one profit number across every channel: it is not a split of organic against paid revenue, and no row here claims a per-campaign net profit figure for any tool.

Why merchants switch
What MerchantFlow does that Lebesgue doesn't
The full P&L, not just marketing performance
Lebesgue lists COGS and profit tracking and custom cost tracking alongside its advertising analytics. MerchantFlow is built around the P&L itself: expenses with CAPEX amortisation, bank balance and burn rate, and a profit number you can trace line by line. We found no CAPEX amortisation or bank balance tracking documented for Lebesgue.
Business Valuation and Product Viability
Know what your store is worth today and simulate a product before you commit inventory. Both are on the MerchantFlow Plus plan. We found neither documented on Lebesgue's site or App Store listing.
Revenue-based funding tracking
Track Wayflyer, Clearco and Shopify Capital repayments inside your P&L (Plus plan). We found no equivalent documented for Lebesgue.
Margin by Region
See net profit, net margin and CAC per country with a cost waterfall. Lebesgue lists revenue by location, but we found no per-country net P&L documented.
Flow AI with three personas
Both products have an AI layer. Lebesgue's Henri AI is capped at 10 questions a month on the $79 plan and unlimited on the $149 plan. MerchantFlow's Flow AI (Pro and above) answers as a CMO, Executive or Finance persona, grounded in your P&L.
Agency portal
MerchantFlow offers a portfolio view across client stores on a separate Agency plan. We found no agency portal documented for Lebesgue.

What their merchants say
Public reviews and testimonials about Lebesgue
Where a public source page is available, we link it so you can inspect the context yourself.
Great app, we use it for profit tracking, also it lets us know how long stock will last approximately.
Solid Attribution App for significantly less money than the comp set.
The description on the shopify app store is misleading. It mentions that in the free plan you have access to COGS: that is FALSE You can enter the cost of products only in the paid plan

What MerchantFlow customers say
Reviews from merchants who run their store on MerchantFlow.
MerchantFlow has become one of the most valuable tools in my business. As a tradie building Mech Tools from the ground up, understanding true profitability is critical. MerchantFlow gives me clear, accurate data that helps me make better business decisions.

I've tried quite a few of these profit tracker apps (even tried making one myself), but honestly, none of them offer what MerchantFlow does and the ones that come close cost 10x the monthly price. My favorite feature by far is the integration with my 3PL, so the data I'm seeing is the actual data not a guess.
Netherlands · 21 days using the app
I've been using MerchantFlow for the last six months in order to better understand my brand's profitability. The tool has without a doubt been super insightful and allowed me to make changes within the business that have nearly doubled our brand's monthly profit. This is the best profit analysis and optimisation tool going around for any ecommerce brand owner right now.
Australia · 6 months using the app
Its super important for me to know my numbers down the the exact percentage and I can trust Merchant Flow to get it right. I've used other softwares in the past but none of them have half of the features this does and always end up not being correct. Highly recommend using it if you're running an ecommerce store.

The honest take
Where Lebesgue still beats us
We think comparison pages should be honest. Here's where Lebesgue is genuinely a better fit than MerchantFlow.
- A genuine free plan with store performance, ad audits and email support, and 4.9 stars across 132 App Store reviews.
- Automated Meta, Google and TikTok ad audits, plus competitor ad intelligence and benchmarks (MerchantFlow does not offer these today).
- A first-party attribution pixel with server-side tracking and Meta CAPI through its Le Pixel plans (MerchantFlow does not have a pixel).
- Pinterest and Microsoft (Bing) ad cost tracking, Klaviyo performance, and predicted LTV (MerchantFlow does not support Pinterest, Bing or predicted LTV today).
- Product and inventory intelligence, including stock-cover estimates, and AI visibility tracking for ChatGPT and AI search on the $149 plan.
- Hands-on onboarding: reviewers repeatedly praise audits and walkthroughs from the Lebesgue team.
- Hosted OAuth MCP connector for Claude, so parity with us on transport and auth.
Questions merchants ask

What are the best Lebesgue alternatives in 2026?
The closest alternatives to Lebesgue for Shopify profit tracking are MerchantFlow, Triple Whale, Lifetimely and Kleio. All of them install from the Shopify App Store. MerchantFlow is our own product, so treat this as our recommendation rather than a neutral verdict: it starts at $49/mo flat with no per-order overage fees, reports one blended profit number across Meta, Google, TikTok and Snapchat, breaks net profit down per country, and supports WooCommerce as well as Shopify. The comparison table on this page puts all five side by side on entry price, blended P&L, per-region P&L and setup, with each vendor's pricing source and the date we last checked it.
How much does Lebesgue cost?
Per Lebesgue's pricing page (checked 4 October 2026): a Free plan, Ultimate at $79/mo, Ultimate AI at $149/mo, and Le Pixel: Attribution at $749/mo, which includes all Ultimate AI features. Le Pixel: Enrichment (server-side tracking and Meta CAPI) is listed at $149/mo and requires Lebesgue Advanced or Ultimate Analytics. The Shopify App Store listing shows annual prices of $711, $1,341 and $6,741 and a 14-day free trial on paid plans.

Is Lebesgue a profit tracker?
Lebesgue lists store performance, COGS and profit tracking and custom cost tracking, but its centre of gravity is marketing: ad audits, LTV, competitor intelligence and Henri AI. MerchantFlow is built around the full P&L, with CAPEX amortisation, bank balance, Margin by Region and, on the Plus plan, valuation and funding tracking. One reviewer reports that entering product costs needs a paid plan, so check the current plan details before relying on the free tier for COGS.
Does Lebesgue have an MCP server or mobile app?
Lebesgue documents a read-only MCP connector for Claude (api.lebesgue.io/mcp, OAuth). We found no native mobile app. MerchantFlow has a hosted OAuth MCP server with 66 read-only tools on every plan, and iOS and Android apps. The app does not send push notifications yet.
Does Lebesgue support WooCommerce?
Lebesgue lists a WooCommerce extension on woocommerce.com and its site says it supports other platforms such as WooCommerce. MerchantFlow supports both Shopify and WooCommerce, though some features such as subscription detection and draft-order B2B detection are Shopify-only.
Can I run MerchantFlow alongside Lebesgue?
Yes. Many merchants pair a marketing analytics tool with a P&L tool. Lebesgue has a free plan and MerchantFlow has a 14-day trial, so you can compare the numbers side by side before deciding.
