Overview
Most ad platforms optimize for clicks and form fills, but they can't see what happens after a lead submits a form. They don't know which leads became paying customers, which deals closed, or how much revenue each campaign actually generated for your agency's clients.
Offline conversion tracking bridges that gap. OffConversion captures every lead with full attribution data, tracks it through your pipeline, and sends conversion data—including actual revenue values—back to your ad platforms when leads convert.
Every lead tracked from first click to closed deal
The Problem
The "Fake Leads" Dilemma
When a lead fills out a form, calls your office, or signs a contract, Google and Meta have no idea. They keep optimizing for cheap clicks instead of the leads that actually become customers. As an agency owner or media buyer, you're left making budget decisions based on cost-per-lead, when what actually matters to your client is cost-per-customer.
Identify exactly which conversions the ad platforms are missing
How OffConversion solves this
OffConversion captures click IDs (GCLID, FBC, MSCLKID, and more) from every form submission on your site, linking each lead to the exact ad that drove it. As leads move through your pipeline and get marked as qualified or won, OffConversion automatically sends that conversion data back to your ad platforms, with exact revenue values attached.
Supported ad platforms
OffConversion sends offline conversions to all major ad platforms via their official APIs. Each platform receives the click ID, conversion value, conversion time, and enhanced conversion data (hashed email and phone) for better matching accuracy.

Conversion event mapping
OffConversion supports multiple conversion events, not just one "conversion" action. You can map custom pipeline stages like "Demo Booked", "Proposal Sent", or "Deal Won", and map each stage to a different conversion action per ad platform.
For example, your "Qualified Lead" stage might map to a Google Ads conversion action called "Qualified Lead" and a Meta event called "Lead", while your "Won" stage maps to Google Ads "Purchase" and Meta "Purchase". Each mapping is fully independent and customizable.
Use cases
High-value B2B sales
Long sales cycles where deals close weeks after the click. Send actual deal values back so Smart Bidding optimizes for revenue, not just early-stage form fills.
Agency reporting
Show clients exactly which campaigns drive real business outcomes. Retain clients longer by reporting on cost-per-customer and real pipeline ROAS instead of just cost-per-lead.
Multi-location businesses
Track conversions across branches and accurately attribute them to the specific local campaigns and ad groups that drove each location's high-intent leads.
