Saasu Integration: Invoice Number

While pushing invoice data into Saasu, you should go with either approach below:


#1: Let the Saasu decide the invoice number (recommended)

This is the recommended approach. You can do this by providing the <Auto Number> from the API. However, please make sure that you escape both < and >. For example:


<tasks xmlns:xsd="" xmlns:xsi="">
 <insertInvoice emailToContact="true">
  <invoice uid="0">
   <invoiceNumber>&lt;Auto Number&gt;</invoiceNumber>


#2: Let the source system decide the invoice number

The source system must keep track of the latest running number and the number must be unique.
