Integration with processmaker

I see that processmaker have database connection that enable it to integrate to other program, and I think it's very possible to integrate frontaccounting with processmaker.

the idea is to use frontaccounting with workkflow from processmaker.

for example for purchase, we can make all employee can submit purchase order via processmaker, only those who approved by GM will be recorded by frontaccounting as purchase order automatically & send email notification to purchasing departemen to execute purchase & email notification to finance department.

after purchasing departement execute purchase request, he/she report via processmaker to finance departemen & automatically record to frontaccounting as purhase invoice.

finance department pay the invoice and report to GM via processmaker and automatically record to frontaccounting as purchase payment.

this integration possible to be implemented to purchasing, manufacturing, sales and any other.

I wish tutorial to implement processmaker report to write in frontaccounting database correctly.
