Common Mistakes to Avoid
Escalating minor disagreements into confrontations
Consequence: Contractor becomes adversarial, work quality declines, and the relationship is damaged beyond repair
Correction: Address issues calmly by referencing the contract and SOW; focus on solutions rather than blame; document agreements in writing
Not having a termination clause in the contract
Consequence: No clear process for ending the relationship if the contractor underperforms, leading to protracted disputes
Correction: Include a termination-for-cause clause with specific triggers, notice requirements, and payment settlement procedures
