Customer Approval Checklist

What this tool is for

Record customer preferences and reviewed decisions without presenting the result as a legal signature. Shop documents preserve who observed what, under which conditions, and with which permission. They are operational records rather than legal, payment, or customer-management systems.

Use it when you can describe the current state and need a defensible next check. It is not a shortcut around inspection: preserve the starting state, change one variable, and verify the result under the same conditions.

Before you begin

Review diagnosis, estimated cost, contact threshold, replacement preferences, old-parts return, cosmetic risk, custom settings, and notification method with the customer.

• Use a stable, tuned instrument unless the page specifically investigates tuning.
• Name the physical reference, unit, and test condition beside every important number.
• Keep the original measurements so any reversible change can be returned to baseline.

Input guide

Customer / owner

identifies the record so its result is not attached to the wrong instrument or work order.

Instrument

identifies the record so its result is not attached to the wrong instrument or work order.

Diagnosis reviewed

classifies an observed condition; choose “unknown” or “not tested” instead of guessing when available.

Estimated cost reviewed

classifies an observed condition; choose “unknown” or “not tested” instead of guessing when available.

Additional-work contact preference

classifies an observed condition; choose “unknown” or “not tested” instead of guessing when available.

Replacement parts preference

classifies an observed condition; choose “unknown” or “not tested” instead of guessing when available.

Return old parts

classifies an observed condition; choose “unknown” or “not tested” instead of guessing when available.

Cosmetic risk reviewed

classifies an observed condition; choose “unknown” or “not tested” instead of guessing when available.

Custom settings / data notes

captures the exact observation, list, or requirement that the result must preserve.

Completion notification

classifies an observed condition; choose “unknown” or “not tested” instead of guessing when available.

Approval date

anchors this record in time so climate, strings, and later work can be compared.

Notes

captures the exact observation, list, or requirement that the result must preserve.

Input labels describe evidence, not targets. A placeholder demonstrates format only; it is never a recommendation for a particular guitar.

How the result should be read

Use unresolved or declined items to constrain the work order. Confirm dates and instrument identity before printing, then retain according to shop policy.

Read priorities from top to bottom, but stop as soon as new evidence contradicts an earlier assumption. Save or print the result ticket with the entered conditions so another person can reproduce the decision.

Method and logic

The checklist captures a conversation and routes exceptions back to the quote. It deliberately avoids pretending that a browser checkbox is a legally sufficient signature.

The page keeps calculation and diagnostic claims deliberately bounded. Display rounding improves readability, while the underlying logic uses entered values; descriptive branches report relative tendencies and the evidence needed to confirm them.

Worked example

A customer approves a $180 setup and fret assessment but requests contact before any work exceeding $220 and wants replaced parts returned. Those limits belong on both approval and job sheet.

The example demonstrates reasoning, not a universal setup specification. Substitute real measurements and repeat the final test before accepting the next action.

Assumptions and limitations

Consent and electronic-signature requirements vary. This page provides operational prompts only; it does not verify identity, store an audit trail, or replace jurisdiction-specific terms.

Instrument design, service history, measurement error, and player technique can outweigh a calculator or checklist. Where manufacturer instructions exist for the exact hardware, use those instructions and record the revision consulted.

Safety and stop conditions

Stop for abnormal resistance, cracking, heat, odor, electrical sensation, moving wood or joints, a measurement that cannot be repeated, or any step that would remove material without a confirmed cause. Secure strings and stored mechanical energy before hardware work. Refer structural, fret-cutting, mains-powered, or uncertain repairs to a qualified technician.
