If you're attempting to set a higher GST rate for your items, but the system keeps defaulting to lower GST rate, here's how you can make sure it's set correctly and you can check below example :
Step 1: When you're entering a sales or purchase voucher in BUSY, the software might remember the last voucher you used and use that rate. To change it to 28%, select Local/Central-28% as the sales or purchase type. Then, press the F4 key, and the system will automatically apply the 28% GST rate to your bill.
Step 2: You can use the sales type as Local/Central Itemwise or Local/Central TaxIncl to ensure the correct GST rate is applied to your items.
