Customer Revision Cost Calculator

Customer revisions can consume engineering and quoting time before a purchase order is placed. This calculator prices revision effort so CAD cleanup, DFM loops, re-quotes, and customer-requested changes can be recovered or documented.

What this calculator does

  • Estimate cost for customer-driven CAD revisions, re-quotes, file repair, and quote updates.
  • a sales engineer needs to decide whether a customer revision should be charged or absorbed
  • Returns the quote impact of customer-driven revision work.

Formula used

  • Captured revision value = revision hours or line items × revision service rate × billable capture
  • Customer revision cost = captured revision value + re-quote/setup charge

Inputs explained

  • Revision hours or line items: undefined
  • Revision service rate: undefined
  • Billable revision capture: undefined
  • Re-quote/setup charge: undefined

How to use the result

  • Use it for CAD repair, DFM loops, tolerance changes, material changes, quantity revisions, and repeated quote updates.
  • It does not decide customer policy; sales strategy may absorb some revision cost for strategic accounts.

Common questions

  • Should internal estimator mistakes count? No. Use this for customer-driven or scope-driven revisions, not internal correction work.
  • Can I use this for CAD repair? Yes, if CAD repair is performed to make a customer file printable or quoteable.
  • What is billable revision capture? It is the portion of revision effort charged to the customer after courtesy discounts or account policy.
  • How does this help quoting? It makes revision effort visible before it erodes quote margin or estimator capacity.
