Coretraks User Guide

Coretraks puts a wrecking yard's cars and parts online so buyers can find them and ask for a quote on WhatsApp. It is a catalog, not an online store.

Here is the whole idea in one sentence: a buyer finds your part on Google, looks at the car it came off, and taps a button that opens WhatsApp with a message already written. You answer on WhatsApp like you always do, and Coretraks keeps a list of everyone who asked about what.

There is no online checkout, no shipping, and no customer accounts. That's by design.

Which part of this guide do you need?

• Buying a part or a car? Read For buyers. It's short.
• Working at a yard? Start with For yard staff, then jump to the task in front of you.

For buyers

How the site works

Each yard has its own web address (for example amautosales.coretraks.com). The home page shows what's in that yard right now:

• Donor cars: wrecked cars the yard takes parts from.
• Parts: the higher-value parts pulled from those cars.
• Cars for sale: whole running cars. When the yard has some, the header shows a Cars for sale link.

Every page has the yard's name at the top (tap it to go home) and a Give us a call link with the yard's phone number. On a phone, tap the number to call.

Find a part

1. Use the filters at the top of the catalog: year, make, model, part category, and maximum mileage. Categories are grouped by system (Powertrain, Brakes, Electrical, and so on).
2. Your choices show as small chips. Tap a chip to remove it.
3. Open a part to see its photos, the car it came off, and its price (or Contact for price). When the yard has added them, you also see a condition grade (Excellent, Good, Fair, or For repair) and notes.

Don't see your part? Open the car it would come from. Its parts are grouped by system, so open just the one you need. Not every part is listed, so use the Ask about parts box at the bottom of the car's page to ask about anything else on that car.

Tap any photo to see it full screen. Use the arrows (or arrow keys) to step through, and ✕ (or Escape) to close.

Cars for sale

A car's page shows its photos, price, VIN, stock number, mileage, title brand, dealership, lot address, and whether it's available. The description may be in English followed by Spanish. Prices don't include tax, title, license, or registration fees.

If a car has sold, its old link says so and points you to the cars available today.

Ask for a quote

1. On a part or a donor car, tap Get a Quote on WhatsApp. On a car for sale, tap Message us on WhatsApp.
2. WhatsApp opens (on your phone or WhatsApp Web) with a message already written. It names the part or car, the last six characters of the car's VIN, and a link to the page, so the yard knows exactly which one you mean.
3. Send it. Someone at the yard replies on WhatsApp with price and availability.

Good to know:

• No account needed. No sign-up or login.
• No WhatsApp? Tap No WhatsApp? Send us a question under the quote button and send the yard your question with a short form instead.
• Nothing is reserved or charged. A quote is a conversation, not an order.
• Local only. Pick up at the yard or arrange local delivery. No shipping.

Share what you find

Your filters are part of the page address, so you can send someone a link to "2014 Honda Civic headlights" and they'll see the same results. Car and part links pasted into WhatsApp or a text show the yard's name and a photo of the actual car or part.

For yard staff

You run Coretraks from your phone. The staff app is built for the yard: big buttons, one thing per screen, and usable with one hand (and maybe gloves on). You only ever see your own yard's cars, parts, and inquiries.

Your day at a glance

Most of the work is one loop:

1. Log a wrecked car when it arrives: scan the VIN and take photos.
2. Publish it so buyers can see it.
3. Get its parts ready: prices, photos, and condition.
4. Post them elsewhere, like Facebook Marketplace, to reach more buyers.
5. Answer inquiries in the Inbox.
6. Mark sold and take down your outside posts.

Cars for sale follow the same idea (see Cars for sale).

The bar at the bottom of the app takes you everywhere:

• Intake: log a new car.
• Cars: your donor cars.
• For Sale: your cars for sale.
• My Yard: your yard's details.
• Listings: every part listing.
• Inbox: buyer inquiries. The badge counts new ones.

Words used in this guide

• Donor car: a wrecked car you take parts from.
• Listing: one part from a donor car, with its own public page.
• Car for sale: a whole running car you sell. Kept separate from donor cars.
• Inquiry: a buyer's request for a quote. Coretraks saves one every time a buyer taps a quote button.

Get set up (once)

1. Go to your yard's site and open the sign-in page (/admin/login). Sign in with your staff login.
2. Add the app to your phone's home screen so it's one tap away in the yard.
3. Set your yard's city. Open My Yard, tap Edit, type the city as City, ST (for example, Alvarado, TX), and tap Save Changes.

Buyers often search with a town name, like "used Tahoe engine Alvarado". With a city set, your page titles read like "Used 2017 Chevrolet Tahoe Engine assembly in Alvarado, TX", which helps local Google searches. Leave it blank to keep titles as they are.

Donor cars and parts

Log a car (intake)

Tap Intake. The form is split into numbered steps, and the line under the title counts how many you've finished. Each finished step gets a tick and folds into a one-line summary. Tap it (or its Change link) to open it again.

1. Scan the VIN. Point the camera at the barcode on the driver's door jamb, or at the stamped plate on the windshield or dash. Coretraks fills in the year, make, model, and trim, and works out which parts fit. If you already took a photo of the VIN sticker or plate, tap Pick a photo in the scanner, and check the VIN when Coretraks asks you to.
2. Check the details and fix anything the VIN got wrong.
3. Pick the yard the car is in.
4. Add notes about the car if you like. This step is optional and doesn't count toward the total.
5. Add photos of the whole car. These are required: buyers look at them first, and parts without their own photos show them. Tap Add Photos to take a photo or pick one from your library. The Shot list under the button names the shots to take (corners, engine bay, interior, odometer, damage) plus a few tips. Ticking shots off is optional and isn't saved.
6. Check the parts. Parts that don't fit this car start unchecked. For example, a transfer case is checked only on 4WD or AWD, a turbocharger only when the VIN says there is one, and there's no engine, turbocharger, or catalytic converter on an electric car. If the VIN doesn't say how the car is driven, the transfer case stays checked and shows Check fitment, so look before you save. Uncheck anything the car doesn't have. Coretraks never changes your choices later.

Save the car when you're done. It waits in intake, hidden from buyers, until you publish it.

Add many cars at once

Starting out with a full yard? Tap Paste a list of VINs at the top of Intake. Paste up to 50 VINs (one per line, or separated by commas or spaces), pick the yard, and tap Start. Each car is saved with the parts that fit it, using the same rules as normal intake.

The results show how each VIN went:

• Created: the car was added. Tap its name to open it.
• Already added: that VIN is already in the system, so it was skipped.
• Could not decode: the lookup returned nothing. Check the VIN, or add the car through normal intake.
• Not a VIN: not a valid 17-character VIN, so it was skipped.
• Not saved: it decoded but saving failed. Try that VIN again.

One bad VIN never stops the rest. These cars have no photos yet, so none are published. Open each one, add photos, check the details, and publish it.

Publish a car

Buyers can't see a new car until you publish it. Get the details right first: the car's web address is built from its year, make, and model, so changing them later breaks links that buyers and Google already have.

On the car's page, the Before you publish list shows what's ready (a tick) and what isn't yet (a dot):

• Photos: ready once the car has at least one. Buyers skip cars without photos.
• Parts reviewed: how many parts the car lists for buyers. It's a reminder to uncheck anything the car doesn't have under Parts to list, and never counts as not ready.

Tap Publish to Public Catalog when you're happy. It always works, even if a row isn't ready. Once published, buyers can also ask about parts you didn't list, from the car's page.

Manage a car's photos

Open the car's page and scroll to Photos.

• Make thumbnail sets the lead photo buyers see first. The current one is labeled Thumbnail.
• ✕ deletes a photo after you confirm. If it was the thumbnail, the next photo takes its place.
• Add Photos adds more after the existing ones. The Shot list is there too.

Cars for sale work the same way.

Get parts ready to sell

Every part checked on a car gets its own listing page automatically. A new listing shows Contact for price and the car's photo. To fill it in, tap Listings, find the part, and tap Edit. There you can set:

• Price and Title.
• Part photos. Optional, but they help it sell. The Shot list names three shots: the whole part on a plain background, its part number or label, and any damage. Saving without uploading keeps the current photo.
• Condition, so buyers know what they're getting:
  • Excellent: works and looks close to new.
  • Good: works, with normal wear for its age.
  • Fair: works, with visible wear or cosmetic damage.
  • For repair: needs repair or hasn't been tested. Sold as is.
  • Not graded: hides the condition from buyers.
• Condition notes, a short line like "Tested, runs".

Not sure where to start? The Needs details tab in Listings shows parts still missing a price, their own photo, or a condition, with the most valuable kinds of parts first. Each row says what's missing. Work down from the top.

Hide a part the car doesn't have. On the car's page, uncheck it under Parts to list. Its page comes down, but its photos, price, and inquiries are kept. Check it again to bring it back. Hidden parts show Hidden in Listings.

Catalytic converters are on hold for legal review. They start unchecked on every new car and show On hold for legal review. Even if you check one, buyers can't see it anywhere until the hold is lifted, and it doesn't count in Parts reviewed. Converter listings you already had are kept, and come back on their own when the hold ends.

The Edit screen also has Check comparables, Draft with AI, and Copy for Marketplace. See Selling tools.

Mark a part sold

In Listings, tap Mark Sold on the part. Its page stays up with a Sold badge, so old links keep working, but it drops out of the normal catalog view. The takedown checklist opens next (see After a sale).

Delete a donor car

From the car's page you can delete it for good: its public page, every part listing, and all its photos. The app asks you to confirm first, and it can't be undone. Use it for a car logged by mistake or one that has left the yard.

Cars for sale

These are whole running cars your dealership sells. They're kept separate from donor cars, and every dealership has them with nothing to turn on.

Add a car for sale

1. Tap Intake, then Selling a whole car? Add a car for sale.
2. Scan or type the VIN and tap Decode. Check the year, make, model, trim, and transmission, and fix anything wrong. If the VIN won't decode, tap Enter the details by hand (your VIN is kept). A car for sale always needs a real VIN. If you already took a photo of the VIN sticker or plate, tap Pick a photo in the scanner, and check the VIN when Coretraks asks you to.
3. Fill in the sale details. Your dealership and its lot address are set for you. Any of these can wait until later.
   • Stock number fills in with your next number: 1001 for your first car, then one past the highest number you've used. You can change it, and Use next number puts the next free one back. Each number can be used once.
   • Mileage (the exact odometer reading) and price.
   • Title brand: Clean, Rebuilt, or Salvage.
   • Location: On the lot, At auction, or In transit.
4. Description (optional). Write English first, then Spanish, in the one box.
5. Photos. Tap Add Photos. The 12-shot Shot list is under it.
6. Tap Save as draft. The car's page opens.

Put it up for sale

A car shows on your public site only when all of these are true:

• its status is For sale,
• it's On the lot, and
• its VIN, stock number, price, mileage, and title brand are filled in.

On a draft or pending car, the Before it goes up for sale list checks the VIN, stock number, dealership, price, mileage, title brand, and location. Each row has a tick or a dot and says what to fix. For sale stays off until every row is ready. A car at auction or in transit can't be for sale, so change it to On the lot when it arrives.

Statuses

Tap one of the four status buttons on the car's page:

• Draft: you're still getting it ready.
• For sale: ready to sell.
• Pending: a deal is in progress. Hidden from buyers.
• Sold: records the date it sold and opens the takedown checklist (see After a sale). Its public page comes down right away, and its old link says it has sold. (Sold parts are different: their pages stay up.)

You can always move a car back, for example from Pending to For sale when a deal falls through. Moving a sold car back clears its sold date and buyer channel.

Find and change your cars

Tap For Sale to see your cars, newest first, with stock number, price, mileage, status, and location (when it isn't on the lot). Filter by Status and Location. Add a car for sale is at the top.

On a car's page:

• Edit any detail and tap Save changes.
• While a car is for sale, an edit that would leave it incomplete (say, clearing the price) isn't saved. Move it to Draft, make the change, then put it back up for sale.
• Photos work like a donor car's (see Manage a car's photos), with the car-for-sale Shot list.
• Delete car for sale removes the car and all its photos for good. The app asks you to confirm first.

The page also has Check comparables, Draft with AI, and Copy for Marketplace. See Selling tools.

Selling tools

These help you price, describe, and advertise what you have. Each one works on parts, donor cars, and cars for sale unless it says otherwise.

Check comparables

Links that search other sites for similar items, to help you set a price. They open in a new tab and are a guide only.

• On a part's Edit screen: eBay sold listings, Facebook Marketplace, and Google, searching for the car's year, make, and model plus the part category.
• On a donor car's page: the same sites, searching for parts from that car.
• On a car for sale's page: Kelley Blue Book, Facebook Marketplace, Google (which adds your city once it's set in My Yard), and the CarGurus home page (search for the car yourself there).

Draft with AI

Builds a prompt you paste into any free AI chatbot to get a title and an English and Spanish description. Coretraks doesn't send anything to an AI service, and it costs nothing. The prompt uses only facts about the item, never notes, inquiries, customer details, or a car for sale's full VIN. You can edit it before copying.

1. Tap Copy AI prompt and paste it into the chatbot. If the chatbot takes images, attach the photos too.
2. Parts and cars for sale: paste the chatbot's English and Spanish description into Paste result and tap Save description. This replaces the description buyers see. On a part, the chatbot's title isn't saved for you; type it into Title if you want it.

On a donor car, the prompt is for social media posts and ends with a link to the car's page. Donor cars have no description, so there's nothing to save.

Copy for Marketplace

Parts and cars for sale only. Gives you the text for each Facebook Marketplace field, so you copy and paste instead of typing. The box only appears while the item is for sale on your site. Otherwise you see a short note explaining why.

1. Tap a field's Copy button and paste it into the matching Marketplace field. Parts have Title, Price, and Description. Cars for sale add Year, Make, Model, and Mileage.
2. Tap Get photos (for example Get 3 photos), then Share on a phone (to save them or send them straight to Facebook) or Download on a computer. A part without its own photos uses the car's.

The description is the one you saved with Draft with AI, or a simple English and Spanish one if you haven't. It ends with key facts (like your dealership and city) and a link to the item's page. That link tells you which inquiries came from Facebook. Prices are whole dollars, so give a part a price before you post it.

Track where you've posted

Every part, donor car, and car for sale has a Where it's posted panel on its staff page. List your outside posts here, so you know what to take down when the item sells.

1. Pick where you're posting: Facebook, CarGurus, eBay, OfferUp, Google, or Other.
2. Tap Copy link and paste that link into your post. It carries a tag (for example, ending in ?src=facebook), so inquiries from it are credited to that site. Other has no tag, so its inquiries count as Website.
3. Add the post's own link (optional) so you can open it later, and check the date posted (it starts as today).
4. Tap Add post.

When you take a post down, tap Mark removed. It stays in the list with the date it came down.

After a sale: the takedown checklist

Marking a part or a car for sale as sold opens this checklist.

1. Where did the buyer come from? Pick Facebook, CarGurus, eBay, OfferUp, Google, Website, or Other and tap Save. If the item had an inquiry, the latest one's channel is filled in for you, so change it if the buyer came another way.
2. Take down these posts. Each outside post still up is listed, with an Open post link when you saved one. Take it down on that site, then tap Removed.
3. Tap Done.

Anything sold that still has posts up shows Still posted in Listings or For Sale. Tap it to open the checklist again.

Inquiries

Work the Inbox

Every time a buyer taps a quote button, Coretraks saves an inquiry, so nothing slips through even if you miss the WhatsApp message. Check the Inbox daily.

Each inquiry shows the car or part, when it came in, and its channel: where the buyer came from, such as Facebook or eBay, based on the tagged link they opened (see Track where you've posted). Untagged inquiries count as Website. Inquiries about cars for sale are labeled (car for sale).

• Open an inquiry to see the listing it came from and the buyer's message.
• Set its status as you work it: New, Responded, Won, or Lost. The team can see at a glance what's handled.
• Filter by status, period, or channel to find what still needs a reply, or to see which sites bring in buyers. The filters work together.

Log an inquiry by hand

For a chat that didn't come through your site, like a Facebook Messenger message, use Log inquiry under the Where it's posted panel. Pick where they reached you, add a note if you like, and tap Log inquiry. It shows up in the Inbox marked as logged by hand, with your note under Notes.

Getting help

• Buyers: tap Get a Quote on WhatsApp to message the yard.
• Yard staff: if something in the app isn't working, contact your platform operator.
