How We Test and Verify Every Claim

Last updated: 24 July 2026 · Maintained by Luke Sandelands

Stack Architect exists because most Shopify automation advice is either vendor marketing or untested rehash. So every factual claim on this site follows one rule: if we can't source it or reproduce it, we don't publish it. This page documents exactly what that means.

Where Our Numbers Come From

In order of preference:

1. Vendor pricing pages and official documentation. Make.com's plan limits come from Make.com official pricing. Meta CAPI behaviour comes from Meta Conversions API documentation and Events Manager. Competitor prices (Elevar, Triple Whale, Klaviyo, Stape, Littledata) come from their own verified pricing indices, as detailed in our Shopify App Pricing Index.
2. Working configurations, built as published. Core solutions like CAPI Shield, Stocky Swap, and Live P&L Automation are written by building the setup step by step and publishing the exact steps that worked — not by summarising vendor docs.
3. Platform announcements with dates. Deadline claims (such as Shopify Stocky's shutdown, Meta's one-click CAPI updates, and Klaviyo billing changes) cite official announcements directly. Learn how to replace Klaviyo for free in our Free Klaviyo Replacement Guide.

We do not use: other blogs' figures, AI-generated statistics, or vendor claims we can't check against a pricing page or changelog.

How Often Figures Are Re-Verified

Every pricing and plan-limit figure is re-checked quarterly, and immediately whenever a vendor announces a pricing change. When Make.com updated its pricing structure, we updated every affected page across our Best Free Shopify Apps 2026 Directory. Comparison tables carry a "verified" date; if that date is more than a quarter old, tell us.

What Our "Tested" Badges Mean

A badge like "iOS tested" means the documented setup was confirmed working under that environment on the date shown — not tested once and assumed fine since. Check our benchmark methodology in the Shopify iOS Attribution Gap Benchmark.

How This Site Makes Money — And What That Buys

Stack Architect is funded two ways, both disclosed:

• Affiliate links. Some links to tools we recommend (marked rel="sponsored" in the page code) pay us a commission at no cost to you. This never changes a recommendation: our core recommendation on most pages is the free tier of a tool, which typically pays little or nothing.
• The Complete Kit ($29 one-time). Pre-built versions of the same automations the free guides teach. The free guides are complete on their own — the kit buys time, not access.

Corrections & Feedback

When we get something wrong, we fix the page, update its "last updated" date, and note material corrections in the text. If you spot an error — a stale price, a changed limit, a claim that didn't hold up in your setup — email support@stackarchitect.xyz or read more about our team and mission.
