# Fees and Invoices

> Fee structures for Iron transactions including transaction fees, banking fees, and network fees. Covers fee profiles and invoicing.

## Transaction Fees

Each transaction may include three fee types:

* **Transaction Fee** – Charged as a percentage of the transaction.
* **Banking Fee** – Charged for the banking rails (e.g., SEPA, ACH, Wire).
* **Network Fee** – Charged by the blockchain network.

## Fee Settlement Methods

For each fee, you can choose the amount that gets deducted on each transaction.

* The fee amount is taken immediately from each transaction amount.
* The fees are accumulated by Iron for you and invoiced monthly.

## Fee Profiles

You can define multiple fee profiles and assign them to customers. A fee profile represents a complete fee configuration that determines:

* Which fees apply.
* How much is charged.
* Who pays each fee (you vs. your customer).

Fee profiles allow you to:

* Offer different pricing tiers (e.g., premium vs. free customers).
* Provide discounted or subsidised fees to selected customer segments.
* Customise the end-customer fee experience without changing backend settlement logic.

### Autoramp-Level Configuration

Fee profiles are configured at the autoramp level, giving you fine-grained control over fees based on currency pairs and payment rails.

This enables you to:

* Apply different transaction or banking fees for the same customer across different autoramps.
* Offer lower fees on preferred currency pairs or payment methods.
* Maintain multiple pricing strategies for a single customer.

### Network Fee Subsidisation

You can choose to absorb blockchain network (gas) fees instead of passing them on to end customers.

* Network fees are not customisable but are calculated at the transaction level (fee = cost).
* Network fees can be configured to be invoiced monthly to you.
* End customers see zero gas fees at checkout when subsidised.
* Configuration is done at the autoramp and fee profile level.

## Invoicing

Iron maintains a clear distinction between:

* The fees charged by Iron to you.
* The fees charged by you to the customer.

Any difference between these two is automatically accounted for during invoice generation.

### How Monthly Invoicing Works

* Fees related to Iron, banking rails, and network accumulate based on the fee profile.
* Your markups and subsidies are tracked separately.
* Monthly invoices reflect:
  * Fees owed to Iron.
  * Transaction fees, network fees, and banking fees deducted.
  * The net amount owed between you and Iron.
