Two customer types, one godown
Dairy cooperatives and oil and gas contractors both buy on formal terms with purchase processes, while the district builds on agricultural money. That mix means referenced invoices for one half and quick cash bills for the other, out of one stock and one ledger.
Industrial contractors and documents
An oil and gas contractor is paid against an audited process, and an invoice missing a PO reference or an HSN code waits another cycle. Those fields come off the item and party records rather than being typed each time.
Agricultural credit alongside
The farm half of the customer list settles after the crop, clustering payment in a few weeks. Ageing rather than a total tells you where you stand before the season, and a limit per party keeps any account within reach.
