Is there a way to change the memo field on a modified .rpc file or invoice to another font?
You can set the default font in the Global Settings screen for the memo and not allow users to change it. For existing memos on the invoices, there is a way to override the font. Instead of using a memo field directly on the invoices, you can use a formula which will override the memo font that gets stored in the database. If you have Crystal Reports designer, you can open the report template (say Project Time & Expense(with memo).rpt) and take a look at the formula:
'@TE_Memo_RTF_ Override'
The report template is available in your BillQuick installation folder typically located at:
C:\Program Files (x86)\BillQuick20xx\Reports\Project\Project Time & Expense(with memo).rpt
