Ask any sales manager how long an average offer takes at their dealership and you'll get a confident answer. Ask them to prove it and the room goes quiet. Most dealerships know their offers issued, their test drives, their closed deals. Almost none know how long a customer actually sits at the sales desk while colour, wheels and optional equipment get specified — and that duration is one of the strongest predictors of whether the deal survives. A 2026 automotive buying-friction study found that 64 percent of customers complete the purchase when the process takes under two hours. Past that threshold, patience and conversion both erode. Yet the desk phase, where most of those two hours are spent, is the least measured part of the entire funnel.
Your CRM starts recording when a lead is created — usually at or near the offer stage. Everything before that is invisible: the walk-in who browsed for eleven minutes and left, the couple who waited fourteen minutes for a salesperson and gave up, the customer who sat through a ninety-minute configuration session and never signed. Your showroom conversion rate, calculated honestly, is closed deals divided by total physical visitors — not divided by logged leads. When dealerships measure it properly for the first time, the number is usually far lower than the one they've been reporting internally, because the denominator was wrong for years.
That denominator matters more than it used to. McKinsey research found buyers now visit an average of 1.6 dealerships before purchase, down from about five a decade earlier. Every walk-in is close to a decision already. Losing one to a slow greeting or a bloated desk session isn't losing a browser — it's losing a buyer who had almost nowhere else planned to go.
The technical answer here is more mundane than most vendors admit: a desk presence sensor mounted under the sales desk on the customer side, registering when someone is actually seated opposite the salesperson. That gives you the true duration of the negotiation and configuration phase — the part where colours are debated, wheel options compared, financing walked through. Because this phase involves specifying so many variables, it can run long, and in most dealerships nobody has ever measured it.
Vemco Group, a Danish company founded in 2005, builds exactly this kind of measurement on a sensor-agnostic platform — Xovis, Milesight, Elsys, Hikvision, Axis and Irisys all plug in — which matters for dealer groups whose sites were fitted out at different times with different hardware. The platform processes more than 85 million counts per day across 2,000+ customers in 95+ countries, runs on AWS in EU-Frankfurt, and pushes data from line cross to dashboard in roughly 2 seconds. Counting accuracy is contractually guaranteed at a minimum of 96 percent, and typically lands at 98–99 percent where lighting, layout and visitor behaviour allow. That honesty about the range matters: a showroom with heavy glare on glass frontage or families clustering at the entrance behaves differently from a clean, well-lit floor.
One implementation detail that trips up almost every first-time dealership deployment: staff contamination. Salespeople cross the entrance line dozens of times a day — walking customers to cars, stepping out for handovers, moving between buildings. Without UWB staff tags excluding employee movements from the visitor count, your denominator inflates and your showroom conversion rate looks artificially weak. Practitioners who have run these rollouts will tell you the staff-exclusion setup is the single step most worth getting right on day one, because retroactively correcting contaminated baseline data is nearly impossible.
Combine desk presence duration with offers issued and total visitor counts, and the funnel stops being theoretical. You can see, stage by stage, where customers leave:
A useful exercise for a general manager: take last quarter's closed deals and divide by measured visitors rather than logged leads. Then compare Saturday's ratio to Tuesday's. High-traffic days almost always show a worse per-visitor conversion, because desk capacity and greeting coverage don't scale with footfall. That single comparison usually justifies the measurement investment on its own.
Data that arrives Monday morning describes a lost weekend. Data that arrives in seconds lets you act while the customer is still on the floor. Real-time alerts — via app, email, WhatsApp, SMS, webhook or MQTT — mean a duty manager gets pinged when visitor count rises while all desks sit occupied, or when a desk session crosses a duration threshold that historically correlates with abandonment. The intervention isn't complicated: send someone to greet, offer a coffee, split the configuration into a follow-up appointment before fatigue kills the deal. What's been missing is the trigger.
For dealer groups, the process angle is bigger still. Once desk duration and per-stage drop-off are measured consistently across sites, you can finally compare like with like: why does one site close in 70-minute sessions while another needs 110 for the same brand and stock? That difference is process, and process can be copied. The dealership that knows exactly how long its offer takes — and exactly where its deals die — stops arguing about opinions in the Monday meeting and starts fixing specific stages with specific owners.
