How do I ask them to approve more work?

A text, an email and a phone script from the numbers on your ticket, plus the authorization record for the repair order. Free, no sign-up, and nothing you type leaves this page.

This page needs JavaScript to work out the numbers and write the drafts. The record's fields and the guidance below still read fine without it.

The ticket
The amount the customer already said yes to, before you found anything else. Every figure here is measured against it, including the percentage the drafts quote.
Pick the row that matches what the tech is looking at. It changes the wording, never the price. Nothing in this list is a diagnosis.
Two lines at most, describing what the tech can see with the parts off. This is the only text the drafts quote, and it never leaves your browser.57 of 180Write what the tech can see, not what it means.
Can they drive it?Your answer decides whether the drafts may say anything about safety. Pick Not safe to drive and they will. Pick anything else and they cannot.
What it adds
The parts and labor you want a yes on, written the way you would write it on the ticket. This is the line that goes into the authorization record. It is not what the tech saw; that is the box above.35 of 120
Parts only, at your selling price. Cores, freight and shop supplies belong here too if you charge for them.
Added labor hours, in tenths of an hour. Multiplied by the shop rate you set under Advanced.
Answer needed withinHours from now. The drafts show it as a clock time, rounded up to the next quarter hour.
Your posted labor rate. It touches the added hours only, never the job the customer already approved.
These figures areA label, not a calculation. We never work out sales tax: whether labor is taxable is a state question, and a wrong total is the number that gets argued about at pickup.

The bar is your own arithmetic: what they approved, what you are adding, and the new ceiling. Nothing in it comes from us.

Text draft

Six drafts appear here: text, email, phone, voicemail, follow-up and decline.

Concatenated SMS capacity depends on the sender's header. This build uses 152 GSM-7 septets or 66 Unicode UTF-16 units per segment, and proves line 1 stays within the 160-septet single-message limit.

One call to a language model that never sees a name, a number, or a word you typed. It rewrites the linking sentences only. If it comes back wrong we keep the template wording and never ask twice.

Authorization record for the repair orderFill it in while you are still on the phone, then attach it to the repair order. Several states require most of these fields when the approval is not in writing.

Fill this in while you're on the call. Your state may also require the same details on the invoice.

Insurer supplements, extended-warranty administrators and fleet approval workflows run their own process; this page is not it. This page writes wording and a record template. It is not legal advice, and state rules on repair authorization differ, so check your own.

How the drafts are built

You typed four numbers and a line about what the tech can see. Five steps stand between that and a message you can send.

Five steps in order: your numbers, fixed clauses, one rewrite, checks, your drafts, with a padlock over the rewrite step marked no customer text sent.

Your numbers

The money goes first, in whole cents, off the four numbers you typed: parts, labor hours times your shop rate, the added total, and the new maximum authorized amount. The percentage measures that added total against what the customer already approved. We round it to a whole number so the message reads like a sentence rather than a spreadsheet. Don't use that rounded figure to test your state's exact limit.

Fixed clauses

We assemble the wording from a fixed library of clauses rather than writing it from scratch. The line carrying the money, the line naming the work you want approved, the question that asks for a yes or a no, the deadline and what happens when it passes are all fixed strings. Your answers pick which ones. Nothing writes them.

One rewrite

The one button on the page sends nine linking sentences to a language model to be rewritten in the tone you picked. It doesn't send your customer's name, your shop's name, your callback number, the vehicle, the repair order, any dollar figure, or either of the things you typed: what the tech found, or the work you want approved. Those stay in your browser and get dropped into the reply afterwards. The model gets placeholders and a rule that it may not write a digit.

Checks

We read the reply back before it reaches your screen: no digits, no invented placeholders, every placeholder still where it was. If it comes back wrong, or doesn't come back at all, we throw it away and you keep the version already in front of you. We don't quietly ask again. One press is one request.

Your drafts

The drafts, the numbers and the authorization record are identical either way. That's why the drafts can't name a part you didn't name, quote a price you didn't enter, or say the work is already done.

The plain version is already the finished message

A complete, sendable message is on screen from your first keystroke, before anything is sent anywhere. Press the button and the linking sentences read better. That is the only thing it changes, and it is why a provider having a bad afternoon costs you nothing but a little polish.

The authorization record is the other half of the job, and it comes off the same answers. Nothing in it waits on the rewrite, so the sheet you print after a failed press is the same sheet you would have printed after a good one.

Questions shops ask

Shops search for an auto repair authorization form. Car owners search for whether a mechanic can charge more than the estimate. Same moment, two sides of the counter.

Can a mechanic charge more than the estimate?

Ask before you go over it. Past that, the rules and who they cover differ by state and by transaction. For covered repairs California wants additional authorization before any charge above the estimate, and New York wants consent before charges exceed an estimate the customer asked for. Washington caps covered repair charges at 110 percent of the written estimate, retail sales tax excluded, unless authorization is obtained first. Florida's written-estimate allowance is 10 dollars or 10 percent, whichever is greater, capped at 50 dollars. In Ohio, when the customer requested an estimate, the trigger is unforeseen, necessary additional work costing ten percent or more of that estimate. Five states, five different tests, and the one you work under may be none of them.

Can a mechanic do work without permission?

Not the extra work, no. Wait for the yes. Go ahead without it and the shop is the one eating the charge, or arguing about it at the counter on pickup day. Asking is the cheap part, which is the whole reason this page exists: a minute instead of ten.

How much over an estimate is acceptable?

State rules set different limits, so there's no single number to give you here. The safe habit is the same at any amount: ask before you exceed it, and write down the answer. Read the two boundaries under their full predicates and they run opposite ways. Ohio's rule bites at an exact ten percent or more. Washington's cap still allows exactly 110 percent of the estimate. The percentage in your draft is rounded for the conversation, so it cannot test either boundary for you.

Does a verbal or text approval count?

In several states yes, as long as you write down the right things. California wants the date, the time, the name of the person authorizing, the phone number called if there was one, what the extra parts and labor are, and the total additional cost. Its regulator's own guidance even shows an additional authorization obtained by text. New York wants the date, the time, the manner of authorization and who gave it, noted on the invoice. Washington adds the name or ID number of the employee who took the authorization, and wants the additional parts and labor written down as well. Write down what you are doing, not just what it costs.

What is a repair authorization form?

It is the document the customer signs at drop-off, agreeing to a described job at an estimated price. This page is not that form. It handles what happens when that form runs out mid-job, and the record it produces attaches to the repair order you already have open.

What do I have to write down when a customer approves by phone?

Whatever your state requires. The record here gives you a broad set of fields to complete, plus two prompts that are easy to miss. One is who the person authorizing is to the vehicle: California lets a customer designate someone else in advance, and that person cannot be the shop, its employee or agent, or an insurer. The other is whether they want the replaced parts back. New York presumes a customer who authorizes by phone does, and does not let that right be waived over the phone.

Does this send the text for me?

No. You copy it into your own phone, your DMS or your texting platform. That's deliberate. Your own channel is the one you can get back into two years from now when somebody disputes the bill. Send it from the shop's number, not a personal phone that gets traded in.

Do you store anything I type?

We don't send or save anything you type in the tool. There's no tool account and no saved authorization record. A Rewrite press sends setting names and our own sentence templates through our server to the language model provider: no name, no number, no vehicle, and neither of the lines you typed. The request is sent to our server and on to the model only to draft the rewrite; those settings are not stored after the rewrite comes back.

What we cannot do for you

This page writes wording and a record template. It doesn't keep what you type, and it doesn't create an authorization for you. Nothing here timestamps anything or proves anything. Five things stay yours.

  1. Send it from a channel you can get back into later, which usually means the shop phone, the shop email or the texting platform. A personal handset gets traded in.
  2. Save the customer's reply as it arrived, word for word, never as a summary. California requires the emails and texts used to obtain an authorization to be kept as part of the same transaction record, for at least three years.
  3. Fill the record in while you are still on the call, and attach it to the repair order then, not at pickup. Copy the required details onto the invoice too, where your state's rule calls for that.
  4. Check that the person saying yes is entitled to say yes for that vehicle.
  5. Keep it as long as your state requires.

One more line and then we stop: this is not legal advice. State rules on estimates and added work differ. The rules summarized here for CA, NY, CT, WA, FL and OH were checked on September 9, 2026 against California Bus. and Prof. Code s. 9884.9 and 16 CCR ss. 3353, 3353.1 and 3354, with the Bureau of Automotive Repair's Write It Right, updated January 2026; New York 15 NYCRR s. 82.5; Connecticut Gen. Stat. ss. 14-65f and 14-65g; Washington RCW 46.71.025; Florida Stat. ss. 559.905 and 559.909; and Ohio Admin. Code 109:4-3-13(C)(2), effective March 21, 2026. Confirm with your state's consumer-affairs or repair-licensing body before you rely on them.
