Database in Access

I need a small databse to coordinate issued gurantees and to be able to generate automatic invoices as well as having an overview list of all running gurantees for a particular period of time. A small interface should be included to be able to edit the existing or add new gurantees. Some other small accounting features are might be needed. This will be a case if a developer proves his knowledge in the first project. The database is Access based. A detailed plan for the neccessary features will be discussed with the developer. The current list in excel contains following columns: Number of the gurantee (should be generated automatically in the future) Issuer (also can include two different issuers who split the costs for the guarantee) Amount (currency changes should be included on automatic basis, whereby the invoices are calculated on the monthly basis and should be saved to the particular date of the currency exchange) Starting date End date thats basically is. The project is a repost since the need for the project has risen up again.
