## Attribution and Conversion Tracking

Topsort supports two attribution layers:

* **Channel-native attribution:** Google, Meta, Snapchat, and TikTok apply their own attribution models.
* **Topsort in-house attribution:** Uses marketplace event data for cross-channel comparability and powers attribution-based reporting in the Topsort UI.

### Why In-House Attribution Matters

* Enables apples-to-apples performance comparison across onsite and offsite channels (including TikTok alongside Google, Meta, and Snapchat).
* Supports configurable attribution windows (for example, 7-day or 30-day windows).
* Standardizes purchase-based metrics for reporting in Topsort.

### Event Sharing

Topsort supports sharing events with offsite platforms via offline conversions API, eliminating need for marketplace to implement tracking pixel, saving implementation time and effort.

## Billing Model

Offsite billing is marketplace-controlled and consolidated:

* Vendors spend against channel-specific wallet capacity (for example, Google wallet, Meta wallet, Snapchat wallet, TikTok wallet).
* Marketplace is billed directly by the channel for media spend.
* Marketplace bills vendors according to its commercial terms.

### Payment Modes

* **Prepay:** vendor funds wallet credits before spending.
* **Postpay:** marketplace sets vendor spending capacity limits; charges are settled later.
