What are the alternatives to Megaplan?

Question

CRM

I use only two modules in Megaplan - Tasks and Finance. They are perfect for my tasks, but I don’t need the rest of the modules, and paying more than 5 thousand for 2 of 8 modules is too expensive. In Tasks, I register an order, and in Finance, I track all income and expenses for each order. Orders can stretch over months or years, so Finance makes it easy to track the bottom line on each order as it closes. Maybe you know some alternatives to this bundle?
