GoHighLevel's SMS and phone system gives auto repair and detailing shops a complete communication hub that handles missed calls, service reminders, and customer follow-ups automatically. Instead of losing potential customers to voicemail or forgetting to remind clients about their next oil change, you get two-way texting, missed call auto-replies, and automated service reminders all in one dashboard.
Most auto repair shops lose 60-70% of their phone leads because customers call, get voicemail, and never call back. They also struggle with repeat business because there's no systematic way to follow up after service or remind customers about upcoming maintenance. GoHighLevel's phone and SMS system solves both problems by capturing every missed call with an instant text message and automating your entire follow-up sequence.
What is GoHighLevel's SMS & Phone System for Auto Repair Shops
GoHighLevel's SMS and phone system is a complete communication platform that handles both inbound and outbound messaging from your auto repair shop. You get a dedicated phone number that can send and receive text messages, automatically reply to missed calls, make outbound calls with a power dialer, and record all conversations in your customer's profile.
The system works like having a virtual receptionist that never sleeps. When someone calls your shop and you're under the hood of a car, the system immediately sends them a text saying something like "hey this is Mike from Downtown Auto Repair. i saw you called but i'm with a customer right now. what can i help you with?" Most people will text back their question instead of hanging up and calling your competitor.
Everything happens inside your GoHighLevel dashboard. When a customer texts you back, it shows up in your Conversations tab just like a chat app. You can see their entire history, what services they've had done, and any notes from previous visits. The SMS messages automatically log to their contact record, so your whole team knows what's been discussed.
The phone system also includes outbound features like a power dialer for calling leads from your CRM, ringless voicemail drops for following up without interrupting customers, and call recording so you can review conversations later. Unlike separate tools like Twilio or SimpleTexting that charge per message, everything's included in your GoHighLevel subscription and connects directly to your customer database.
Why Auto Repair & Detailing Shops Need SMS Communication
Auto repair customers expect immediate communication, especially when their car is their lifeline to work and daily activities. Text messaging has a 98% open rate compared to 20% for email, and most people read texts within 3 minutes of receiving them.
Think about your typical customer interaction flow. Someone calls because their check engine light came on, you diagnose the problem, order parts, and complete the repair. Without a systematic communication process, that customer might call three times asking "is my car ready yet?" Each interruption pulls you away from billable work. With SMS, you can send automated updates: "parts arrived, starting work on your Honda now" and "your car is ready for pickup, total is $347."
Service reminders are where SMS really shines for auto repair shops. Most customers forget when their next oil change is due or when they need their inspection renewed. You can set up automated text campaigns that remind customers 30 days before their service interval: "hey Sarah, your Honda Accord is due for an oil change in 4 weeks. reply YES to schedule or call us at (555) 123-4567."
The seasonal opportunity is huge too. Before winter, you can text all your customers about winterization services. Before summer road trip season, send brake and tire check reminders. These proactive texts typically generate 15-20% response rates and help you stay top-of-mind when customers need service.
SMS also helps with the awkward payment conversations. Instead of calling to say "your transmission repair estimate is $2,800," you can text the estimate with photos of the damaged parts. Customers can process the information privately and respond when they're ready to discuss options.
Setting Up Your Phone Number and Missed Call Text-Back
The missed call text-back feature alone will capture more leads than any other single thing you can set up in GoHighLevel. When someone calls and you don't answer within 3-4 rings, the system automatically sends them a text message introducing yourself and asking how you can help.
Step 1: Purchase Your Phone Number
- Go to Settings > Phone Numbers in your GoHighLevel dashboard
- Click "Add New Number" and choose either local or toll-free
- Search for numbers in your area code if you want local, or pick any toll-free number
- Local numbers cost $2/month, toll-free are $5/month through LC Phone
- Complete the purchase and wait 2-3 minutes for activation
Step 2: Enable Missed Call Text-Back
- Navigate to Settings > Business Profile
- Scroll down to "Missed Call Text Back" section
- Toggle it ON and write your auto-reply message
- Keep it under 160 characters to avoid message splitting
- Always identify yourself: "hey this is [your name] from [shop name]. i saw you called but i'm with a customer. what can i help you with?"
The timing settings matter. i recommend setting the delay to 30 seconds so if you're just finishing up with a customer, you have time to grab the call. But don't set it longer than 60 seconds because by then, the caller has already hung up and moved on.
Your auto-reply message tone should match your shop's personality. If you run a high-end detailing service, maybe something like "hi this is David from Precision Auto Detailing. i'm currently with a client but saw your call. how can i help you today?" For a neighborhood garage, keep it more casual: "hey it's Tony from Tony's Auto. saw you called - what's going on with your car?"
Pro tip: Test your missed call text-back by calling your shop number from your personal phone. Let it ring until voicemail, then see how long it takes to get the text. The message should arrive within 10-15 seconds of the call ending.
Configuring Two-Way SMS Conversations
Two-way SMS turns your phone number into a chat platform where customers can text you directly and you respond from your GoHighLevel dashboard. Every conversation automatically saves to the customer's contact record, creating a complete communication history.
The Conversations tab in GoHighLevel works like any messaging app. When a customer texts your business number, it appears as a new conversation thread. You can see their name (if they're already in your system), their phone number, and any previous interactions. Messages are delivered instantly, and you get desktop notifications so you don't miss anything important.
Setting Up Two-Way SMS:
- After purchasing your phone number, it's automatically SMS-enabled
- Go to Conversations > SMS to see all your text message threads
- Click any conversation to view the full message history
- Type your reply in the message box at the bottom
- Press Enter or click Send - the message delivers instantly
The real power comes from integration with your customer database. When an existing customer texts you, GoHighLevel automatically pulls up their profile, service history, and any open estimates. If someone texts "is my car ready?" you can instantly see they brought in a 2019 Subaru Outback for brake work on Tuesday.
You can also send proactive texts from the contact record. If you're running behind on a repair, go to the customer's profile, click the SMS tab, and send an update: "hey Mike, your transmission repair is taking a bit longer than expected. should be ready by 4pm instead of 2pm. sorry for the delay!"
For auto repair shops, common SMS conversations include appointment confirmations, pickup notifications, estimate approvals, and service reminders. The key is responding quickly. customers expect text replies within an hour, unlike email where they might wait a day. Set up mobile notifications on your phone so you can respond even when you're not at your desk.
Important: Always identify yourself in the first text of any new conversation. customers might not have your business number saved, so start with "hi this is [name] from [shop name]" before diving into your message.
Automating Service Reminders and Maintenance Alerts
Automated service reminders are the biggest revenue driver for auto repair shops using GoHighLevel's SMS system. Instead of hoping customers remember their oil change is due, you can set up workflows that automatically text them based on mileage, time intervals, or seasonal schedules.
The key is building reminder sequences that feel helpful, not pushy. Start with a soft reminder 30 days before service is due: "hey Sarah, your Honda Accord is coming up on its 5,000 mile oil change interval. want to schedule ahead of time?" Then a follow-up at 2 weeks if they haven't responded, and a final reminder when they're actually due.
Creating Service Reminder Workflows:
- Go to Automation > Workflows and click "Create Workflow"
- Choose "Date-Based" trigger for time intervals or "Custom Values" for mileage tracking
- Set your trigger conditions (30 days before next service date, for example)
- Add an SMS action with your reminder message
- Include a call-to-action: "reply YES to schedule" or your phone number
- Set up follow-up messages for non-responders
Mileage-based reminders work great for oil changes, but you need to track odometer readings in custom fields. When a customer comes in, always ask their current mileage and update their contact record. Then you can trigger reminders based on "current mileage + 5,000 miles" for regular oil changes.
Seasonal reminders are easier to set up and often more profitable. Create workflows that trigger on specific dates: winter tire reminders in November, AC checkup texts in April, pre-summer road trip inspections in May. These catch customers when they're already thinking about their car's seasonal needs.
i covered this integration strategy in my guide to GHL automation for auto repair shops, but the reminder workflows become even more powerful when you combine them with your service history data. customers who had brake work done can get brake pad wear reminders, transmission service customers get fluid change alerts, and so on.
Pro tip: Include the customer's vehicle make and model in reminder texts. "your 2018 Honda Civic is due for its oil change" feels more personal and relevant than a generic "your vehicle needs service."
Power Dialer and Outbound Calling Features
GoHighLevel's power dialer lets you call through leads systematically without manually dialing each number. You can call from your computer using a headset, automatically log call outcomes, and immediately follow up with SMS or email based on the conversation result.
The power dialer is perfect for following up on estimates, checking in with customers who haven't been in for a while, or calling leads from your website contact form. You can load a list of contacts, hit start, and the system dials each number automatically. When someone answers, you're connected instantly. If there's no answer, you can leave a pre-recorded voicemail or mark it for SMS follow-up.
Setting Up the Power Dialer:
- Go to Marketing > Phone and click "Power Dialer"
- Create a new calling session and select your contact list
- Choose your caller ID (your business phone number)
- Set up disposition codes: answered, voicemail, busy, no answer, callback requested
- Upload or record voicemail drops for unanswered calls
- Click "Start Calling" and the system begins dialing
Call recording is built into the system, which is incredibly valuable for training and quality control. You can review calls to see what objections come up most often, how your team handles pricing discussions, and which approaches work best for different types of customers. All recordings are automatically saved to the contact's profile.
Ringless voicemail is another powerful feature. Instead of calling and hoping they answer, you can drop a voicemail directly into their inbox without their phone ringing. This works great for non-urgent follow-ups like "hey this is Mike from Downtown Auto, just wanted to check how your car's been running since we did the brake work last month."
The system tracks all call metrics: connection rates, talk time, disposition outcomes, and follow-up actions. You can see which calling sessions generate the most appointments and which scripts get the best response rates. This data helps you refine your approach over time.
For auto repair shops, outbound calling works best for estimate follow-ups, maintenance reminders for high-value customers, and reactivating customers who haven't been in for 6+ months. Don't use it for cold calling random people, but it's excellent for your existing customer database.
Integration with CRM and Customer Profiles
Every SMS message, phone call, and voicemail in GoHighLevel automatically logs to the customer's contact profile, creating a complete communication timeline. This integration means your entire team can see what's been discussed with each customer, eliminating the confusion that happens when multiple people handle the same account.
When a customer texts "is my car ready?" you don't have to search through paper work orders or ask around the shop. Their GoHighLevel profile shows exactly what service they're having done, who's working on it, and any previous conversations about timing or complications. You can respond immediately with accurate information.
The contact profile includes custom fields for vehicle information: make, model, year, VIN, mileage, service history, and preferred contact methods. When someone calls or texts, this information displays automatically so you can personalize the conversation. "hey Mike, calling about your 2017 Ford F-150" sounds much more professional than "uh, what vehicle did you bring in?"
Communication triggers based on customer data are where this gets really powerful. You can set up workflows that automatically text customers when their repair status changes in your shop management system, when parts arrive, or when their vehicle is ready for pickup. The key is connecting your existing processes to GoHighLevel's automation engine.
Notes and tags help organize customer information for better communication. Tag customers as "high-value," "fleet account," or "seasonal customer" and create different communication sequences for each group. Fleet customers might get detailed service reports via email, while individual customers prefer simple text updates.
Pro tip: Use GoHighLevel's activity timeline to prepare for customer conversations. Before calling someone back, spend 30 seconds reviewing their recent interactions, service history, and any open issues. This preparation makes every conversation more productive and professional.
The system also tracks communication preferences automatically. If a customer always responds to texts but never answers calls, their profile will show "prefers SMS" so your team knows the best way to reach them. This data builds over time and helps you communicate more effectively with each individual customer.
