Additive Manufacturing Service Bureau Quoting calculator
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.
