ManPower Sourcing Charges

Dear all,
Please consider this:
I am running a Man Power sourcing firm by which i have agreement through Online Email-ID which proves that a particular company is assigned us on their Man Power requirements at the rate of 8.33 % of total annual CTC which they will pay us on completion of 90 days from the date of Joining.
Now are all our candidates which we have placed have completed their 90 days and even more, Company is not seeming to pay our charges for which we have send them an Invoice.
Please let us know what is the procedure to get our payments.
Thanks and Regards

1) save/ start documenting all correspondences which lead to the recruitments.
2) start sending reminders on e- mail. Escalate the issue to all the Directors, not only HR.
3) hire a lawyer and proceed to legal notice if your payments do not come through. Will cost but if your case is valid and strong you will win along with costs and damages.
You could also try speaking to other friendly TPRs who are also dealing with the company. Sometimes it works.
No one wants to leave a good client. A good client is one who appreciates your efforts and pays up if not on time at least within a reasonable extension of that.
All others are just a drain on your resources and to be avoided.
Just my thoughts.
