We have a web store selling hand embroidered garments. You may check www.vandastore.in. Currently woo commerce generates invoices and packing slips using third party plugin.
What I wish that if ur software can be integrated via some plugin which can generate invoices as per gst law and fetch its data to ur main software for further accounting process, it we'd be grt.
If you people develop this plugin, I m sure, u would get a score of clients like me who are doing small online business.
