INTRO: Are you using Financial Force, Accounting Seed, Sage One or any other financial/accounting application for Salesforce? Have you ever needed to generate a custom check to mail out? Conga can help with that. We've seen that requirement many times and have even created a custom template for specific check stock.
THE NEED: Custom checks out of Salesforce.com
THE SOLUTION: Conga Composer with a custom word template.
Here is a standard Conga Composer window showing all your options to merge your "Check" template, save a copy to notes and attachments and update an activity (if you choose).
Here's your check output. It's as simple as creating a button, formatting a Word Template and MERGE!
