A careful cost-plus quotation proceeds in four steps:
1. Ascertain the genuine first-contract price.
2. Add only expenditures recognized as countable costs.
3. Distinguish the actual purchase price from the accumulated cost.
4. Disclose the agreed profit and final payable amount.
Example: first price Rs 8,000, allowable processing Rs 1,000, profit Rs 900, sale price Rs 9,900. The amount described as the original purchase price must remain accurate.
