Right information leads to right invoicing and seamless business operations. Let’s begin the article today with a real-life scenario.
Imagine you have launched a small business. You found a billing template online and made the invoice for the payment. A few months later, your customers inform you they cannot claim ITC (Input Tax Credit) because your bill is missing mandatory GST details.
