How to Send Service Reminders and Bring Customers Back to Your Garage in Portugal

Think about the last time you repaired a car and the customer walked away happy. What happened next? At most garages, the honest answer is: nothing. The customer left and there was no structured way of following up. Six months or a year later, when their IPO (Portugal's mandatory periodic vehicle inspection) was about to expire, they may well have searched online for a garage — and possibly found one of your competitors. Service reminders solve this problem. They turn a one-off customer into a repeat customer, and cost almost nothing to send.

Why Retaining Customers Is More Profitable Than Winning New Ones

Marketing research consistently shows that winning a new customer costs five to seven times more than keeping an existing one. For independent garages with limited marketing budgets, that's a critical fact. Your existing customers already trust you. They've handed you their car keys once before — they'll do it again if you stay on their radar. A well-timed service reminder is one of the most cost-effective ways to make sure they call you first instead of searching for someone new.

The Three Most Valuable Types of Reminder

Not all reminders carry the same weight. Some services are legally required and create a genuine sense of urgency. Others are recommended and give you a chance to demonstrate your expertise. Understanding which reminders generate the most bookings helps you prioritise.

• IPO reminders: The most powerful reminder you can send. The IPO (Inspeção Periódica Obrigatória — Portugal's mandatory periodic vehicle inspection) is a legal requirement, and almost every vehicle owner wants to be warned when it's approaching. Send a reminder four to six weeks before the expiry date to give the customer time to book.
• Annual service reminders: Remind customers roughly 11 months after their last service that they're due again. Many drivers lose track of when they were last serviced, and a well-timed reminder positions you as the expert looking after their car.
• Seasonal checks: Air conditioning checks in spring, battery checks in October, and brake inspections are good hooks for a targeted reminder campaign. They create urgency without being intrusive.

Setting Up Service Reminders with Car Spot

The Car Spot Contacts Dashboard is where your customer records live. After every job, log the customer's name, contact details, registration plate and the date the work was carried out. With this information, Car Spot can flag upcoming reminder opportunities so you know exactly which customers have an IPO or service coming due, and can reach out to them at the right moment.

What to Say: Writing Reminders That Get a Response

The best service reminders are short, clear and helpful in tone. Customers don't want a sales message — they want to feel that you're looking after their car. A message like: Hello Mr Silva, just a heads-up that your Renault Clio's (XX-00-XX) IPO is due next month. We can book you in — call us on 21 XXX XXXX or reply to this message. is friendly, specific and easy to act on.

• Use the customer's name — it makes the message immediately more personal.
• Include the vehicle's registration plate so they know exactly which car you mean.
• State the specific service in question and when it's due — be precise.
• Give a clear, easy call to action: a phone number, a link, or a reply option.
• Keep it brief — five sentences or fewer is ideal for an SMS or email reminder.

SMS vs Email: What Works Best for Garage Reminders?

Both have a place in a well-run reminder strategy. Text messages have open rates above 90% and are typically read within minutes of arriving — making them ideal for time-sensitive reminders. Email works better for longer communications, such as a seasonal newsletter or a detailed maintenance schedule recommendation. For pure booking-conversion reminders, SMS tends to win.
