can I use bit coin to pay my overseas customers I have a business where I have to pay customers on other countries , I want to have the ability to transfer my funds to a bank in another country with out having to pay the high bank fees for transferring funds
Absolutely! Bitcoin can be transferred peer to peer, to anyone over the net.

Now, you should note that:


Bitcoin is very volatile.
Bitcoin is very congested and slow these days, using litecoin or ethereum may be a better pick at the moment.


Also too, you will need to make sure your oversea customers will accept bitcoin payments. Some countries do not have a online exchange available to cash in bitcoins, so it is very important to tell your customers if bitcoin payments are ok.

tl;dr - yes, you can send bitcoin payments to anyone, in any country as long as they accept it. Then, your customer can optionally choose to cash it at a online exchange available to him for fiat cash.
