SELECTIONS & VARIATIONSHow one choice changes the total
Suppose a tile supply allowance is ₹75 per sq ft and your selected tile is ₹95 on the same ex-tax basis, for an agreed 400 sq ft quantity.
- Original allowance credit
- − ₹30,000
- Selected tile supply
- + ₹38,000
- Net supply change
- ₹8,000
- Illustrative tax at 18%
- ₹1,440
- Illustrative change total
- ₹9,440
Teaching example only. Installation is assumed unchanged. Confirm the measured purchase quantity, wastage, freight, handling, any markup, tax treatment and time effect in the actual quotation. A material change also needs technical acceptance.
Approve the written net change and any revised date before ordering or changed work.
INVOICES & RECEIPTSA payment does not close an inspection
An invoice should identify the contractual milestone, measured or certified work and its supporting release records. Advance payments and other agreed payment types should be described separately.
Simple payment example: an invoice with ₹1,00,000 payable and a bank receipt of ₹60,000 has ₹40,000 still outstanding, assuming no deductions or credits. The receipt records what arrived; it does not change the certified work or its acceptance status.
For an actual invoice, reconcile tax, advance recovery, retention, applicable deductions and credits under the signed agreement. Label disputed amounts and resolve them through the agreed procedure.
Keep three records distinct: work accepted, amount payable and money received.
