iSous is an invoice manager program for Mac OS X. With it you can merge invoices using Pages. You can also track those invoices and record payments.
To generate invoice you usually need a template. With iSous you don't need to know HTML to design you own. Simply use a word processor and voila !. Insert merge field in your document (see Preferences for the list of merge fields). It is not necessary to use Pages to track you invoice and payment. If you want you can only record an invoice without generating a Pages document.
