## Short answer (TL;DR)

Industry average attach rate on service contracts sits at 5-10%, top dealerships hit 40-60%. The difference isn't sales talent; it's process. The 5 levers are: default pricing on the sales contract, monthly price over total, automatic follow-up for no-thanks, workshop as upsell channel and monthly measurement per salesperson.

## Why your attach rate is stuck at 10%

- Service contract mentioned last, as an add-on, customer mentally done with the deal
- Salesperson shows the total price (DKK 23,400) instead of monthly (DKK 650)
- No follow-up on the 90% who said no the first time
- Workshop never gets the cue 'here's a contract-less customer, propose one'
- No measurement per salesperson, so you don't know who converts 40% and who sits at 4%
- Standard pricing doesn't exist, salesperson gives 30-50% discount 'to close'

## The 5 levers that move attach rate 4-5x

### 1. Default pricing on the sales contract

Show the contract as default on every offer: 'Car: DKK 285,000 + 650/mo service contract (can be removed)'. The default effect alone moves conversion from 8% to 35-45%. It's the single biggest change.

### 2. Monthly price over total

DKK 23,400 sounds like a lot. DKK 650/mo sounds like streaming. Use the monthly price in offers, contracts and communication. The customer compares with Netflix, not with a big bill.

### 3. Automatic follow-up on no-thanks

Customer said no? Month 3: SMS 'same price still available'. Month 6: 'first service in 2 months, sign up now?'. 30-40% of no-thanks sign up within 12 months.

### 4. Workshop as upsell channel

Every time a contract-less customer books service, the system flags reception: 'offer service contract'. Workshops convert 15-25% of these, on a channel where you don't pay for the lead.

### 5. Monthly measurement per salesperson

Dashboard: attach rate per salesperson per month. When the sales manager sees that Anna hits 45% and Peter hits 5%, you can coach, adjust standards and focus effort. 5-10 percentage points per quarter is realistic.

## What a high attach rate gives you

- **4-5x MRR per sold car** — From 8% attach × DKK 650 = DKK 52 MRR/car to 40% × DKK 650 = DKK 260 MRR/car. On 30 cars/mo = DKK 7,800 extra MRR/mo, growing DKK 93,600/mo every 12 months.
- **Top dealer benchmark: 40-60%** — Top dealers in DK hit 40-60%. Not luck, process. You can hit the same level in 6-12 months.
- **Predictable growth** — When attach rate is stable at 40%+, you can budget MRR growth precisely based on cars sold. The pipeline becomes predictable.
- **Less dependence on sales talent** — When standards run automatically, you don't have an 'A-team / B-team' problem. Even your newest salesperson hits 30%+.
- **Re-activation of no-thanks works** — 30-40% of no-thanks sign up within 12 months, if you remember to ask. An automatic flow is the difference between 'forgotten' and 'recovered'.
- **Sales manager 1:1s become concrete** — Instead of 'sell more contracts' the sales manager can say 'your attach is 12%, the module runs as default, so what happens in the conversation?'. Concrete coaching instead of platitudes.

## Frequently asked questions

### What's a realistic attach rate on service contracts?

Industry average is 5-10%. With default pricing on the sales contract + automatic follow-up most reach 35-50% within 6-12 months. Top-tier dealers hit 50-65% when they also use workshop as upsell channel and measure per rep monthly.

### How fast can I move my attach rate?

Default pricing on the sales contract can be implemented in 2-4 weeks and typically gives a 20-30 percentage point lift in the first month. The other levers (follow-up, workshop, measurement) add 10-15 percentage points over 3-6 months.

### Do I need to train salespeople to move attach rate?

Training helps marginally, process helps 10x more. Default pricing and standard packages remove the biggest friction: that the salesperson has to 'remember and calculate'. When the process runs automatically, even the newest salesperson hits 30%+.

### What's the single biggest lever?

Default pricing on the sales contract. That alone typically moves attach rate from 8% to 35-45%. It's not an 'add-on' when the customer sees it as standard, it's part of the car.

### Why does monthly price work so much better than total?

Psychological anchoring. DKK 23,400 activates 'big bill' circuits in the brain and triggers resistance. DKK 650/mo activates 'streaming subscription' patterns and feels insignificant against the car price. Same product, 4-5x conversion.

### How do I measure attach rate accurately?

Attach rate = (contracts signed this month) / (cars sold this month). Measure per salesperson, per model, per period. CARRUSLiNK provides this in a live dashboard, no Excel export.
