Debt Recovery Case Management System

My client requires a database application to manage their growing debt recovery client base. The process consists of receiving a caseload of debts from multiple clients (typically hotel chains, leisure clubs etc.). The cases are debts owed to the client by one or more individuals (debtors). The debtors are contacted by my client and his team of five employees to attempt to arrange repayment of the debt. Ideally repayment should be in full and immediate, however; the debt is more usually cleared by way of a monthly/weekly instalment plan. These instalment plans need to be recorded against each debtor and payments allocated to the account on receipt. Missed payments should be flagged as ‘arrears’ on the account status. When a debt is paid in full, or otherwise settled, the case is closed. The case can also be closed for non-payment reasons, such as debtor absconded, no contact, deceased and more. At the end of each period (typically monthly) my client invoices (externally) his clients for any recovered money. This is done on a commission basis for any payments received with a minimum invoice amount. There is no fee for non-collection. Interest is charged on all outstanding debts calculated on a daily basis, payable by the debtor. We are looking for a Cloud Based solution, ideally based on the Microsoft Azure platform, with a web/internet client application. We can build the database in consultation with the developers if required. Please see atached file for rough spec.
