Your real customer acquisition cost is total sales and marketing spend divided by the number of new customers your store or backend actually confirmed - not the order count your ad platform claims. That distinction is the whole point, because platforms tend to overstate. In jujugrowth's own June 2026 test store, one platform claimed 50 orders, GA4 measured 18 purchases, and the Shopify store confirmed only 10 paying customers. If you calculate CAC against the claimed 50, your number looks far better than reality; jujugrowth keeps the store-confirmed number visible so platform claims can't grade themselves. jujugrowth connects read-only through each platform's official login to your store or app, your analytics, and your ad accounts, then puts ad-platform claims, analytics numbers, and store-confirmed outcomes side by side in your currency. That lets you divide real spend by real customers to get a CAC you can trust. Your break-even point for ad spend is where the gross profit you earn from a customer equals the cost you paid to acquire them: break-even revenue per customer = CAC ÷ gross margin. Above that, each customer is profitable; below it, you're bleeding spend. jujugrowth watches this daily and flags drift before your next billing cycle - for example, retargeting spend that quietly drifted from $14 to $23 per purchase over nine days in its own test store. It shows the dates, the math, and a suggested cap before any change, and account writes stay off by default until you approve.
Ad platforms count conversions using their own attribution, which often overstates results. In jujugrowth's own June 2026 test store, the platform claimed 50 orders while the store confirmed only 10 paying customers. jujugrowth places platform claims, GA4 numbers, and store-confirmed outcomes side by side so you divide spend by customers that actually paid, not by inflated claims.
jujugrowth connects read-only to your store or backend, your analytics, and your ad accounts through official logins. It compares what each ad platform claims with what your store or subscription backend actually confirmed, keeping the store-confirmed number visible. That gives you a spend-over-real-customers figure instead of one based on platform-reported orders.
Break-even is where gross profit from a customer equals your CAC, so break-even revenue per customer equals CAC divided by gross margin. jujugrowth watches your connected numbers daily and flags when spend drifts past what a purchase is worth - for instance retargeting that moved from $14 to $23 per purchase in its test store - and shows the dates and math before suggesting a cap.
No, not by default. jujugrowth connects read-only and account writes are off unless you turn autonomy on yourself after the read-only review. It recommends a suggested cap or fix, and you approve every change; each approved action has a set budget ceiling and is recorded in the audit log.
Yes. Broken tracking can hide real revenue and skew acquisition math. In jujugrowth's own daily watch it caught $69 of real revenue that GA4 reported as $0 and a signup-loop break where 606 sessions produced one signup. Surfacing these gaps keeps your CAC and break-even numbers grounded in real outcomes.
