Make plugin work with WordPress Multisite

Hi,

We were really excited to install this plugin in our WordPress site and automate various parts related to invoices, delivery notes, shipping labels… but we haven’t thought thoroughly about our multisite situation. Our store is translated in 4 different languages and every different language is a different site, which this plugin interprets as a different store, thus creating a different invoice number for each “store”. Is there a way to harmonize and unify each “different store” so invoicing follows each other and doesn’t start a different number for each store. This is not allowed in our law and we could have problems.

Thank you in advance for your help!
