Neither ProfitMetrics nor Addingwell is Littledata, so here's where Littledata wins:
vs. ProfitMetrics: ProfitMetrics focuses on profit/POAS reporting rather than comprehensive data collection and audience enrichment. Littledata's identity resolution and automatic checkout tracking make it a stronger foundation for feeding clean, complete data to marketing platforms.
vs. Addingwell: Addingwell uses server-side Google Tag Manager, which still depends on browser-initiated tags — meaning it can miss events the browser doesn't see and limits customer data enrichment. Littledata pulls directly from Shopify's servers, capturing the full customer journey including server-side checkout events browsers can't see.
Littledata's key advantages over both:

ProfitMetrics vs Addingwell's customer reviews
| ProfitMetrics | Addingwell | Littledata | |
|---|---|---|---|
| Example product review | "I waited another two weeks. Nothing. Only replies when I followed up myself. After about a month and a half of waiting in their support queue, I’d had enough. I uninstalled the app and removed all their scripts… but even now, I still see their script showing up in my orders." | Setup took just a few seconds, and it works right away. All my pixels from GTM are now server-side and perfectly connected. So much money saved on ads. | "We were having difficulties with accurate and consistent revenue attribution...With Littledata implemented, we now get consistent and accurate revenue attribution." |
| Example support review | "Very complicated app, poor support – a frustrating experience... completely unprofessional, overly complicated, and really poor communication." | The support was very fast to answer our questions and super helpful. Just be careful to check that the events don't trigger twice. | "Customer support is absolutely amazing... you can never go wrong when an app does what it says and tacks on great service!" |

ProfitMetrics focuses on profit-based tracking — it sends margin/profit data to ad platforms, not just revenue. Its limited destinations reflect a specialized, profitability-first approach.
Addingwell is a pure server-side tagging solution (Google Tag Manager Server-Side), offering broader platform coverage. It prioritizes accurate event tracking across more ad channels.
Littledata has the widest destination coverage, including CRM/retention tools like Klaviyo, Attentive, and Segment — making it stronger for brands that want server-side data flowing into email, SMS, and data warehouse ecosystems, not just ad platforms.
Key distinction: ProfitMetrics = profit intelligence; Addingwell = ad platform accuracy; Littledata = full-funnel data routing including retention and analytics stacks.
