We have a client to whom I was selling a software solution. The client required 2 licences and issued two separate purchase orders for the same. The total development cost was more than the amount in a single PO, but the understanding was that the two POs will together cover our costs.
Each PO contained two items
1. The product with a 1 year warranty
2. An AMC for 3 years after the warranty
The product was delivered and paid for according to the first PO and the warranty expired in January 2014. We were supposed to have signed and AMC contract for the same and raise invoice for it which did not happen and we continued free support so far.
The second product was not accepted for delivery since the client requirement changed. So after 2 years of negotiations we decided to stop the free support and not to enter into an AMC according to the first PO
My questions are
1. Is it legal for me to refuse to enter into an AMC when I already delivered one item in the PO
2. Is there a legal recourse to make the client pay according to the first PO?
