Ad Attribution Beyond CPL: Why Your Ads Manager Says 1,310 Leads and Your Bank Account Disagrees

How joining Meta and Google ad spend to Razorpay orders and firing server-side CAPI events trains ad algorithms to find buyers instead of form-fillers.

1-min readPublished Updated By the Supersei team

Every founder has lived this meeting: the performance marketing agency reports a record-low ₹180 Cost Per Lead (CPL) and 1,300 leads for the month, yet collected revenue is flat. When you optimize Meta and Google campaigns purely for form submissions, the ad platform's algorithm finds people who love filling forms — not people who pay invoices.

How closed-loop revenue attribution works

  1. Store click IDs on arrival: Capture fbclid, gclid, UTM campaign, ad set and form ID on the lead record the second they enquire or chat on your site.
  2. Collect inside the CRM: When the buyer pays a Razorpay or Stripe payment link (including partial instalments), the gateway webhook marks the order Paid and flips the deal to Won.
  3. Feed real buyers back via CAPI: Supersei automatically fires the verified purchase value back to Meta Conversions API (CAPI) and Google Enhanced Conversions, training the ad algorithm on collected rupees rather than raw form fills.
