5 questions to ask before buying GST & e-invoicing software
How GST & e-invoicing software is priced

GST & e-invoicing software in India: common questions
Is GST software different from accounting software?
Accounting software records transactions; GST software specialises in returns, reconciliation and e-invoicing at scale. Many companies use both.
What is GSTR-2B reconciliation?
Matching your purchase records with what suppliers reported, so you only claim input tax credit you are eligible for.
Do we need a GSP?
Large filers usually connect through a GST Suvidha Provider for automation; smaller businesses may file through the portal or their accounting tool.
