'Find best architecture for current laravel base ecommerce

we have a big eCommerce system with 6 different panels including (inventory, finance, seller, manage, call-center, front)
all of the code wrote in a monolith laravel application.
now we have so much complexity and spaghetti codes and we need to find the best alternative architecture for this application
is it a good solution to separate each panel logic into different applications and all of them connect to the same and unique database?
i should mention that we don't have enough developers and knowledge for moving into microservice architecture
