Suit on Note Vs Suit on Account?

I am filing a suit against a contractor who failed to complete a work order/poorly completed the few items he did do. He has been paid in full already and did not complete the job. I served him with the demand letter and now need to file the actual suit against him, but I am unsure which box to check off on the Complaint. This is in Georgia. We had a contract, not signed by either party, full amount paid to him, work was not completed on 80% of the contract. Two items were completed but not to terms of the contract and not to industry standards.
