Dear experts.
Q#
scenario,
ABC company is providing manpower services or labour to XYZ company.

XYZ company will pay full amount to ABC company If a labour serves in XYZ company for 6 months. XYZ will pay against Bill as a consultation fees plus GST.

ABC company will file the return as per the service bills made.

If a labour left his job before 6 months XYZ co is deducting the amount in next bill as service incomplete or service returns but ABC has already filed GST and paid tax.

My question is.
