I am a freelance trainer. I provided a training to staffs of PSU through one of their vendors. The vendor has issued me a PO.
It has been more than 45 days, but the vendor has not paid me any amount as of now. they are not replying to my email and on phone they simply say that they have not received the money from the PSU. They say that will pay me once they receive from them. (I have the call recordings with me)
They have received my invoice and have acknowledged the correctness of the same in the email. I have given them the certificate of successful delivery of the training issues by the Manager from the PSU.
The time line for payment is not mentioned in the PO. And I did not notice this.
On the PO they have mentioned: 100% against delivery
What are my options now ? And also what are the precautions I must take in future.
Shall be grateful to you for your advice.
