einvoice - a Go library to read, write and verify electronic invoices

Work in progress

This library will be used to read, write and verify electronic invoices (XML) which conform to the EN 16931 standard.

Installation

go get github.com/speedata/einvoice

Usage

invoice, err := einvoice.ParseXMLFile(filename)
if err != nil {
	...
}
// now invoice contains all the information from the XML file

writing an invoice:

func dothings() error {
	inv, err := einvoice.ParseXMLFile("...")
	if err != nil {
		return err
	}
    // or better, create all the necessary fields yourself


	return inv.Write(os.Stdout)
}

Limitation, current status

Coding just started, only the basic parts are implemented.

• Reading and writing of EN 16931 ZUGFeRD XML files is possible

• Some checks can be performed (BR-1 to BR-41)

• XML output for minimum and EN16931 ZUGFeRD profile

• No UBL based XML

These points will be addressed. Stay tuned for updates!
