Keep the calculation and the accepted proposal together.

A fictional quote

An estimate contains 4 units at 125 each and an optional service at 80, giving 580 before any applicable tax or adjustment. If the rate later changes, decide whether an already sent quote retains its original price, expires or must be revised.

That is a business rule. The system should not silently recalculate an accepted document using today's rate.

Make calculation order explicit.

List inputs, units, effective rates and adjustment order. Agree whether rounding happens per line or on the total. Have the responsible adviser supply tax and accounting rules for the actual business.

Define exceptional pricing.

State who can override a rate, approve a discount or add work outside the standard options. Store a reason and decision with the quote rather than relying on a separate email.

Identify sent and accepted versions.

Give each revision a clear identity. Mark superseded proposals and decide what an old acceptance link should show. The acceptance record should identify the proposal, version and relevant time.

Test the handoff.

An accepted proposal may create a project or another record. Repeat the acceptance event in a controlled test and verify it does not create duplicate work. Check what staff see if the destination is unavailable.

Prepare a first review.

• A fictional ordinary estimate with known expected totals.
• An optional item, boundary quantity and manual adjustment.
• A rate-change example and a revised proposal.
• The approval owner and accepted-work destination.
• A fallback process and the person maintaining the rules.
