ERP Internals/Modules/Service Management
Most businesses do repair and maintenance work on the products they sell. If the work is done under warranty, there is no charge to the customer. Service Management schedules on-site and depot service, defines product warranties, handles service contracts, and controls whether there are charges. Contrast this with Preventative Maintenance. Not every ERP package has a Service Management module although all the large ones do.
Service Management shares the Customer group of tables with Accounts Receivable. It has a Contract table which contains one record for each service contract with each customer. Associated with this Contract table is a Transaction table which contains one record for every service performed under that contract.
Service Management creates invoices in Order Entry/Invoicing.
