How do I measure aftermarket revenue per customer?

Sum all workshop revenue, product sales (tires, battery, accessories) and service contract MRR per active customer over 12 months and divide by active customer count. Industry average sits at EUR 1,100-1,600/year. Top dealers hit EUR 2,200-3,000. CARRUSLiNK pulls the number automatically in a live dashboard.

What's the most important lever?

Service contract attach. From 8% to 40%+ delivers an MRR lift of EUR 400-540/year per new customer, and locks them to your workshop. Default pricing on the sales contract + in-flow digital signature is the single most important feature.

How long until I see results?

Service reminder flow shows results in 3-6 months. Service contract attach lift takes 6-12 months (only new car sales). Tire hotel and trade-in flow show results in 12-18 months. Expect a full 25-40% lift 12-18 months after all 5 flows are running.

Should salespeople and mechanics get a bonus on aftermarket?

Yes, it drives behavior. Salespeople get a bonus per service contract sold (typically EUR 30-70). Mechanics get a bonus per upsell on visit (typically 5-10% of upsell revenue). Both pay for themselves 10-20x.

What's the CARRUSLiNK ROI here?

A dealer with 1,000 active customers lifting aftermarket from EUR 1,200 to EUR 1,800 per customer/year earns EUR 540k extra annually. CARRUSLiNK costs EUR 1,000/mo = EUR 12k/year. ROI: ~45x. Conservatively 5-10x year 1, 20-40x from year 2.

Can I do this without a unified system?

In theory yes, in practice nearly impossible. The 5 flows require shared customer cards, shared consent log and shared automation engine. Excel + 3 separate tools breaks the data and gives customers 4 different messages. A unified platform is required.

Aftermarket revenue per customer, how to lift it 25-40%

Most dealers earn EUR 1,100-1,600 per customer per year after the car sale. Top dealers earn EUR 2,200-3,000. The difference isn't the customer, it's how systematically you sell service, tires, battery and trade-in. Here's how to lift it.

Short answer (TL;DR)

Aftermarket revenue per customer is measured as total workshop and product revenue per active customer over 12 months. Industry average: EUR 1,100-1,600. Top dealers: EUR 2,200-3,000. The gap is driven by 5 things: service contract attach, automated reminders, tire hotel, battery/wear flow and trade-in flow. CARRUSLiNK delivers all 5 in one platform.

Why aftermarket revenue is low

No one tracks revenue per customer, only aggregate KPIs
Service bookings are reactive (customer calls) instead of proactive (we send SMS)
Tires sold as one-off, not as a hotel agreement with recurring visits
Battery and wear parts only spotted when the car won't start
Trade-in only discussed after the customer has gone to a competitor
Salespeople and mechanics have no incentive to sell service contracts

The 5 levers that work

1. Service contract on every car sale

Default on the sales contract, not an afterthought. Attach rate from 8% to 40%+ delivers ~EUR 1,050/year per new customer (EUR 92/mo). 5x lift in service contract MRR.

2. Automated service reminders

SMS 4 weeks before each interval, based on km or date. 40-60% conversion. Fewer customers lost to the local independent = EUR 400-700/year extra per customer.

3. Tire hotel + seasonal flow

Offer tire hotel with every new tire purchase (free for 5 years). 2x annual swaps at EUR 110-160 = EUR 220-320/year per hotel customer. Plus recurring contact.

4. Battery and wear flow

Trigger SMS when car is 3+ years (battery) or 50,000+ km (brake pads, wipers). 20-30% conversion. ~EUR 70-200/year extra per customer.

5. Trade-in flow

Reach out 90 days before the natural switch moment. 8-12% buy a new car from you. Each trade-in triggers a new service contract, tire hotel and typically a tire purchase.

What the 5 levers move combined

25-40% lift in 12 months

Dealers implementing all 5 flows typically lift aftermarket revenue per customer from EUR 1,200 to EUR 1,800, a 50% lift without more customers.

MRR from service contracts

Stable monthly payments deliver better cash flow and higher business value (5-7x ARR vs 1-2x car sales).

Workshop utilization up 20-30%

Proactive flows fill low season and spread load. Mechanics work more evenly, less overtime, fewer rush jobs.

Higher retention

Customers with 4+ touchpoints per year have 70%+ retention after 3 years. Customers with 0-1 touchpoint: 35-45%.

Better next-car conversion

When the customer has a service contract + tire hotel with you, conversion on the next car is 55-65% vs 25-30% without.

Higher business value

Dealers with 40%+ service contract attach trade at 5-7x ARR. Car sales only without recurring: 1-2x. For a mid-size dealer = EUR 1-3M difference at sale.
