Create Custom Invoice Design Using Canva or MS Office Template Merged

Reckon One existing invoice templates seem to meet legal requirements, however the design is quite basic. We have found through experience the design of our invoice can impact the speed of payment from customers.
We would like to see an integration that would allow us to use our existing invoice template from MS Word. An alternative might be an integration with your fellow Sydney Tech firm, Canva to give users the ability to create better designed invoices that get paid faster.
