In the past few years, we have covered plenty of themes and plugins for financial institutions, banks, and investment firms. HYIPLab for WordPress is also worth a look. It is an advanced plugin that lets you turn your website into an investment business. It gives you control over interest type, return period, and other aspects of your business.
This plugin supports over 25 payment gateways. It is responsive and has a reporting system with graphics and charts to help you make sense of your data. You will be able to track total investments, interests, and other data points in the back-end. HYIPLab also has a bunch of custom widgets and supports a multi-layer referral program.
