AutoEstimate is built for independent repair shops and mobile mechanics. Check the car in, add the work, and send your customer a professional PDF estimate — then turn the same job into an invoice when the work is done. No account, no desktop software.
The first launch takes two short steps. There's no account to create — everything you enter stays on your iPhone and in your private iCloud.


Your location also sets the currency, the registration numbers your documents need, and any local requirements — you can change all of it later under Settings → My Shop.
Tap the + button on the Jobs tab. A new job takes two steps — the work itself is added afterwards, because the car is often checked in before you know what it needs.
Step 1 — CustomerStart typing the customer's name. Returning customers show up as suggestions — tap one to pull in their phone and email. For a new customer, just fill in the name and phone (email is optional) and tap the arrow.
Step 2 — VehicleA returning customer's vehicles are listed at the top — tap one to reuse it. Otherwise pick the Year, Make, and Model (choose Other… if the model isn't listed), and add the mileage, VIN, license plate, and color if you have them. Tap the checkmark to create the job.


The job opens straight on its Work Items tab, ready for services. Changed your mind halfway? Tap ✕ and Discard — a discarded job isn't counted against your free jobs.
On the vehicle step, tap the camera button next to the VIN field and point your iPhone at:
AutoEstimate checks the VIN's check digit before accepting it. If a printed VIN can't be verified, it stays highlighted on screen — tap it to use it anyway. Use the flashlight button in a dark bay.
As soon as a full 17-character VIN is in — scanned or typed — the year, make, and model fill in automatically.
Note: Decoding a VIN into year, make, and model looks it up in the NHTSA vehicle database, so it needs an internet connection. Without one, the VIN is still saved — just pick the year, make, and model yourself.
The Jobs tab is your home screen. Each card shows the customer, vehicle, services, total, and where the work stands — a job's status is about the work itself, separate from its estimates and invoices:
A red Overdue badge joins them when the job's invoice is past its due date and still unpaid.
Search by customer name, vehicle, or service, or tap the filter button (top left) to narrow the list by status and date range.
Swipe right on a job to mark its estimate as sent (handed over in person) or its invoice as paid. Swipe left to duplicate a job for a repeat visit, or delete it.

Inside a job, the header shows the total with tax, split into labor, parts, and tax, the vehicle (tap the VIN to copy it), and the customer with Call, Text, and Email buttons. Below it are two tabs: Work Items and Documents.
On Work Items, tap + to add services:


Catalog services come in with labor filled in but no parts price — parts vary too much from car to car. A service still waiting for a parts price is flagged so you don't send it out by mistake. Tap Reorder to change the order services print in, or swipe left on one to remove it.
Job status. A job moves from Draft to In Progress by itself once you create its first estimate or invoice. From then on it's yours to set: tap ⋯ → Job Status and pick Paused (waiting on parts or on the customer), Completed, or Cancelled — any status, any time.
Estimates and invoices keep their own status on the Documents tab — Draft, Sent, Paid, or Overdue.

Tap any service to open it.

Custom lines have a Type, so the extras print the way customers expect:
The Documents tab lists every estimate and invoice created for the job, newest first, with its number, amount, and status.
To quote the work, tap + → New Estimate:



The PDF opens right away, with your logo and shop details, the customer and vehicle, labor and parts for each service, and the totals. Tap the Share button to send it by Messages, Mail, WhatsApp, or AirDrop — it always goes out as an attached PDF, never as a public link. Once it's sent, the estimate is marked Sent. Handed a printed copy over the counter instead? Swipe right on the job and tap Mark Sent.
Estimates are frozen: once created, an estimate never changes, even if you edit the job or your shop settings later. If the work changes, create another estimate — it's numbered as a revision (-R1, -R2…). The customer approves it however you normally work, by phone, text, or in person.
When the work is done, go to the job's Documents tab and tap + → New Invoice:



An invoice that's been sent, isn't paid, and is past its due date is marked Overdue — on the Documents tab and with a red badge on the job card. When the customer pays, swipe right on the job in the Jobs list and tap Mark Paid. Enter the payment date and method (cash, check, card, bank transfer, or other). From then on the invoice previews and shares with a PAID stamp — handy as a receipt.
Numbers are never reused: invoices are numbered in sequence across your whole shop. Only an invoice that hasn't been sent yet can be deleted (swipe left on the Documents tab); a sent or paid invoice stays as your record.
Every customer you enter on a job is saved to the Clients tab automatically — no separate data entry. You can also tap + to add one by hand, search by name, phone, or vehicle, and change the sort order from the menu at the top left.


Open a client to see what they've spent with you, call, text, or email them, and browse their vehicle history and past jobs — look up what you did last time before the car is even on the lift. Use the menu to start a New Job for them with their details already filled in.
The Catalog tab starts with My Services — services of your own — followed by every built-in service by category with its typical price range.
Tap any service to open it in the same form you use to edit a service on a job: name, type, labor (flat or hours × rate), parts (one amount or itemized), and tax. Save it, and from then on it comes into every job exactly that way. Catalog services with your own price are marked with a dot; ↺ puts one back to the catalog's price.
Tap + to add a service of your own — a pre-purchase inspection, a mobile call-out fee, anything you do often. My Services come first in Add Services → From Catalog, and you can add the same one to a job as many times as you need.


You can also save from a job: turn on Save as my default price when editing a catalog service, or Save to my catalog on the Custom tab.
Settings → My Shop holds everything printed in the header of your documents:
Settings → Document Defaults controls how documents are priced and printed:


Local rules built in: in Ontario, estimates carry the required statement that the final bill can't exceed the estimate by more than 10%, and ask for a completion date. In California, invoices can list replaced parts the shop kept (such as cores). Settings only change documents you create from then on — ones you already sent stay as they were.
Go to Settings → Export Invoices and pick a period — this or last quarter, this or last year, all time, or a custom range.
You get a CSV file with one row per invoice, with labor, parts, and each tax in its own column. Leave Include PDFs on to get every invoice PDF too, all in a single .zip. Unsent invoices are left out unless you turn on Include unsent invoices.
Tap Export and send the file by Mail, save it to Files, or AirDrop it to your computer.

AutoEstimate saves everything on your iPhone and backs it up to your private iCloud, so your jobs follow you to a new phone. The iCloud status is shown at the top of Settings. NVKLabs never sees your data.
Deleted jobs and clients aren't gone right away — they wait in Settings → Recently Deleted for 30 days, and you can restore them from there. Deleting a client doesn't touch their jobs.
AutoEstimate is free to start. The only limit on the free plan is 3 jobs in total — after that, you'll be asked to upgrade before creating a 4th. Settings shows how many free jobs you have left.
Everything else — VIN scanning, estimates and invoices, the service catalog, PDF styles, and invoice export — is included on the free plan from day one. Pro removes the job limit, with weekly, monthly, or annual billing. Manage or cancel your subscription anytime from Settings → Manage Subscription.
