Items and three sets of buyers
The item list is quick. What deserves care is the party list, because you are billing into Chandigarh, Punjab and Haryana in an ordinary week and each is a different tax treatment. Setting the correct state on every party at setup means the bill applies CGST and SGST or IGST correctly from then on without anyone thinking about it.
A planned city and its tricity catchment
Chandigarh's material trade serves the city itself along with Mohali and Panchkula, which means a supplier routinely bills across three different tax jurisdictions in an ordinary week. Construction here is organised and the buyers expect documents to match.
Three jurisdictions, one counter
A sale within Chandigarh, one into Punjab and one into Haryana are three different tax treatments, and getting them wrong is a filing problem rather than a rounding one. Setting the buyer's state on the party is all that is needed — the bill applies CGST and SGST or IGST automatically with the correct state code printed.
Organised buyers and clean paperwork
Contractors and institutional buyers here clear invoices on the fields they carry, and a bill missing an HSN code or a PO reference waits another cycle. Because the codes live on the item and the reference is a field on the bill, the paperwork is right without anyone remembering to make it right.
