Orangis did not have annual maintenance contracts for any of our web maintenance projects. Our postpaid billing system was designed to help small businesses. However, the uncertainty of the final bill worried many of our customers as per our latest survey conducted to a sample number of clients. So we have come up with Annual Maintenance Contracts for web maintenance so that you pay in advance for the 12 months web maintenance. Your AMC is calculated based on the last 5 years of billing data.ANNUAL-MAINTENANCE-CONTRACTS
