Recently implemented one of US client - We have a talented pool of technical professionals that having experience in Business central, 1. This includes all standard accounting and reporting as well as Purchasing, Sales (and all other standard Nav modules). 2. We will go through the setups with the user and enter in the usual parameters in order to get an operational company going. This includes number series, payment types, batches, users, etc. Minimal security settings are included. 3. We assume that Chart of Accounts, Customer, Vendors, and Items are readily available and mapped according to Microsoft Dynamics NAV standard. 4. We assume legacy GL data is readily available. We can set the system not to require balancing by document no. but the date is mandatory. 5. We assume the open AR/AP transactions are in an excel format and map to existing fields in the sales and purchase Journals.
