Question : Billpay API

We working on a project where the use should be able to pay bills online and have the service send a paper check on their behalf... I know it's a little confusing to describe since this isn't the bank..

Do you know of any service that allow users to do that?

Answer : Billpay API

Sorry, I thought completion should be after registry:
SELECT [dateToLandRegistry]-[dateOfCompletion] AS Expr1, [completion matters].[completion ID], [completion matters].clientName, [completion matters].completedBy, [completion matters].dateOfCompletion, [completion matters].dateToLandRegistry
FROM [completion matters]
WHERE ((([dateToLandRegistry]-[dateOfCompletion])>30));
