Is it possible to customise the invoice to show non-standard information?

Yes, invoice templates are 100% customisable. While there are 'standard' data rows that will be printed on the invoice, everything else is customisable. Some of the customisations include:

• Printing regulatory and compliance information;
• Printing static instructions, e.g., payment transfer details;
• Printing branding and organisational information;
• Printing custom columns based on data available to the system.
