zoho books Document workflow

zoho books Document workflow

Hi,

We are looking into documents to optimize our workflow. When we receive an invoice, auto-scan / upload it to zoho books documents, we would like to have a feature where you can assign some sort of workflow for that invoice:

with the workflow it must be possible to assign tasks to the invoice e.g.
approve the invoice;
create a bill
match it to a project
etc
etc

Sure, some task are possible but I can't seem to find a general approve function. Is that not yet available / perhaps on a roadmap?
