How BOQ flows to Sales Order & Invoice
1
BOQ entered in Velantra
Each item: unique Item Code, Unit, Qty, Rate. This is the contract schedule of quantities agreed with the client.
2
Push BOQ to ERPNext Sales Order
Each BOQ line becomes an SO line item. Rate and Qty carried across. SO Total = Contract Value. GST type confirmed as Works Contract.
3
Pour Cards reference BOQ item codes
Rate auto-filled from BOQ master. No manual rate entry at pour creation or billing.
4
RA Bill aggregates certified M-Book quantities
RA Bill pulls M-Book quantities per BOQ item, applies contracted rate, calculates billing amount for the cycle. PM approves.
5
Sales Invoice raised — SO line partially closed
Velantra creates a standard ERPNext Sales Invoice from the approved RA Bill. Each invoice line references the SO line item, progressively reducing the outstanding balance. GST (Works Contract 12%/18%) applied. SO billing status auto-updates.

Billing Traceability — BOQ item → M-Book → RA Bill → Sales Invoice
Revision rules: Each upload creates a new revision. Already-billed quantities are locked at the rate active at billing time. Rate changes only apply to future M-Books. Item codes are immutable — add a new item instead of changing codes.
