hello
I wonder if there is the possibility of incorporating invoice vm several websites and at the same time that the numbering of invoices are correlated between them,

explain:

if we sites
A: invoice number 1
B: invoice number two
C: invoice number 3

and the posterior

to the site A: The next bill would be 4

and so on simultaneously

so that the turnover of the company does not see duplicate

Is there something similar?

Is there any solution?

I appreciate any help.

Thanks
