4) Freelancer F works on this and delivery the result.
5) After Freelancer D delivery the result. System send the information of bank account of admin to Employer. Employer check and manually transfer $100 to that bank account.
You have to enable the credit system to use the cash payment.
This is the flow:
1) Enable the credit system.
2) Employer post 1 job => wait freelancer bid on his job.
3) Hire 1 freelancer who bid in his project. => he have to deposit credit to his balance via cash payment.
You can enable the cash payment option and show your bank account detail in this payment. If employer select this payment – they have to manually transfer the fund to your bank account(outside the system). After you got the fund in your bank account – you can approve this.
