Execute a local powershell script on a Remote Machine

Hi all,

I have a need to run a powershell script on a remote machine. But  the PS1 script has to be in local. I cannot copy the script on every customer machine to execute it. Rather is there a way that the script I have in my local machine can do all its functions on a remote machine and report back the results??. I have done enough googling and finally came here.. This may be a unrealistic stupid question. But I wanted to give a try asking the experts.
