Brightpearl

Brightpearl is an Online Accounting Software with built-in CRM functionality for relatively well performing retail/wholesales businesses and comes with a lot of features. Yet, stuffed with various functions, Brightpearl proved inflexible when it comes to editing data/ past transactions.
There are also gaps in the workflow, which do not serve for better user experience, and critical bugs
