Repair Quote Generator

What this tool is for

Calculate labor, parts, tax, discount, deposit, and balance with cent-safe arithmetic. 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

Enter each labor and parts row with description, quantity, and unit amount. Select currency, tax basis, discount, deposit, validity, and assumptions before calculating.

• 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.

Quote date

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

Quote number

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

Currency

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

Labor rows

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

Parts rows

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

Tax (%)

provides a measured or counted input; confirm the allowed range and repeat the reading before relying on it.

Discount amount

provides a measured or counted input; confirm the allowed range and repeat the reading before relying on it.

Deposit

provides a measured or counted input; confirm the allowed range and repeat the reading before relying on it.

Estimated completion

provides a measured or counted input; confirm the allowed range and repeat the reading before relying on it.

Quote validity

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

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

Check every subtotal against shop policy, especially whether tax follows discount and which lines are taxable. The printed quote should name excluded work and an approval path.

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

Line amounts are converted to integer cents, then labor and parts subtotals, discount, tax, total, deposit, and balance are calculated in a fixed order to avoid binary rounding drift.

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

Labor “setup | 2.5 | 60” is $150; parts “strings | 2 | 12.50” is $25. With $5 discount, 10% tax, and $50 deposit, total is $187 and balance $137.

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

Tax, currency, deposit, and quote-enforcement rules vary by jurisdiction. The tool does not process payment, lock prices, manage inventory, or create a legal contract.

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.
