Best way to Give a Client Credit?
What would be a good way to give a client Credit for something they bought. Example:
I have a DB for Contacts / Clients.
I have DB for invoices.
what i would LIke to create is in Contacts i enter in manually BUT do not want just anyone to do this, and be able to then have the "Credit" show when creating an invoice and the option to click "Use Credit" for use on the next purchase. does this make sense? then if they do click it, then the Credit gets removed from the Contacts DB and amount is deducted from the Invoice.
