I think at Refrens it must give users a feature like a error should be shown if a product or item is put in the invoice and by mistake if wrong GST tax rate is put for a HSN code of actual different Tax rate then it should verify and show error for manual entry mistake and should notify and to change it to correct GST % Tax Rate?

Don’t you think this as game changing and very useful tool for all your clients?Because I don’t think any one till now provides such service?
