Change the series of a sales invoice in Unisolve



You may want to change series of sales invoice with starting of new financial year. At present your invoices are using 1CC or xSS as invoice series depending upon whether your data is having multiple principals or not. Another issue is that in case of distribution invoice it is not printing 1SS and uploading invoice in GSTR 1 with series as 1SS. In the version 16.2.39 release dated 15 May 2019, we have addressed these issues and added a new column in invoice table with GST Ref. No. It contains the same invoice no which is updated to GSTR 1 earlier. In future, you may want to change this series and we have provided the option in principal master for the same.
