{% hint style="warning" %}
When configuring some payment gateways you must authorize the following IPs :\
`167.88.149.182`\
`18.211.189.236`\
`54.204.55.35`\
`52.35.240.234`\
`52.32.57.169`\

`52.58.96.97`\

{% endhint %}

### Transaction Fee

If you want to set a fee when customers pay using a particular gateway, enter the percentage in the **Transaction fee** section. This option is not available on all payment gateways. This fee will be added to the invoice that is paid via the payment gateway.&#x20;

As the fee will be added as a new invoice line, you can optionally choose to charge [tax rate](https://legacydocs.nexudus.com/platform/day-to-day/finance/taxes/about-tax-rates) as well as assigned a [financial account](https://legacydocs.nexudus.com/platform/settings/billing-and-accounting/accounts) to it.

{% hint style="info" %}
There are additional charges of $/£/€10/month + $/£/€0.04/per transaction for certain payment services options on Nexudus.
