Monetizing Support and Maintenance Contracts

Many IT agencies and web development firms offer ongoing Managed Service Agreements. A typical contract provides an included monthly allotment of support hours (e.g., 20 hours/month on the Gold Plan) with additional support billed at an overage rate of $120/hour.

Automating Overage Calculations

Manually reconciling monthly ticket hours against contract caps is labor-intensive and prone to missed overage billing. Advanced billing software automatically meters ticket hours and generates supplemental overage invoices the moment the cap is exceeded.

Automate your SLA contracts with Relaso's Agency & Retainer Invoicing Suite.
