Can I have document layouts in the ERP other than those proposed?

No. Our models are made to respect international standards and this for 3 reasons:
- compatibility with window envelopes
- the obligation for certain ISO standardised companies to comply with standards
- the obligation to structure documents so that they can be readable by RFOs

You are free to change the colours, the logo, the texts of the conditions, etc: but the global layout
canvas must respect the above mentioned standards.
