# Parafin

> Sync Parafin capital activity into your customers' books.

If your platform offers business financing through [Parafin](https://www.parafin.com/), Layer can import that activity directly. Advances, repayments, and fees post to each customer's books, and outstanding balances are carried as liabilities on their balance sheet.

## Setup

Grant Layer access to your Parafin data and map each Layer business to its Parafin recipient. Your Layer contact will help you establish the connection.

Layer records proceeds when capital is deployed and tracks repayments as they occur, including repayments collected as a share of sales. When the customer's [bank data](/guides/importing-bank-data) is connected, the cash movement reconciles against their account activity, keeping balances and financing costs accurate in their [reports](/guides/reporting).

This integration is enabled per platform. Reach out to your Layer contact to turn it on.

## Importing directly instead

To push financing activity to Layer yourself, use the [Loans API](/api-reference/loan/loan) to record loans, proceeds, and payments. The [loan data guide](/guides/importing-loan-data) covers Layer's loan model, including [merchant cash advances](/guides/loans/merchant-cash-advances) and other financing structures.
