The verdict in three sentences
For a 40,000 m² logistics warehouse in Marseille where trucks wait an average of 2 h 10 before unloading, a dock appointment scheduling platform costs between 20,000 and 45,000 EUR excl. tax (about USD 22,000 to 49,000) and goes live in 10 weeks. Slots by dock and goods type, SMS call-forward to the driver and a WMS connector bring waiting time below 40 minutes. Detention fees billed back by carriers fall by nearly 90%, which pays for the project within months.
Why trucks wait
In a warehouse near the port of Marseille, as in most logistics hubs, waiting rarely comes from a lack of docks. It comes from arrivals bunched between 6 am and 10 am, carriers who do not know which dock awaits them, goods (chilled, oversized pallets, port containers) that require a specific dock and crew, and a gatehouse that runs everything by phone and paper log.
Standard transport terms include free waiting time (often 1 to 2 hours depending on agreements), beyond which the carrier bills detention. With an average wait of 2 h 10, the bill piles up, and drivers start refusing loads to the site.
| Platform feature | Effect on the ground | Share of budget (2026 order of magnitude) |
|---|---|---|
| Online slot booking | Carriers and suppliers pick a free slot | 20% |
| Rules by dock and goods type | Chilled, bulk, pallets, containers, computed duration | 20% |
| Kiosk or gatehouse check-in | Appointment check, plate, documents | 15% |
| SMS call-forward to driver | "Dock 12 free, please proceed" | 10% |
| WMS connector | Expected orders, receiving status | 20% |
| Dashboard and punctuality | Delays by carrier, no-show rate, saturation | 15% |
Waiting time and detention fees before and after
Assumption: 80 trucks a day, 250 working days, so 20,000 visits a year.
| Indicator | Before (no appointments) | After (platform) |
|---|---|---|
| Average wait before docking | 2 h 10 | 38 min |
| Visits exceeding free time | 18% | 3% |
| Average billed overrun | 1 h 15 | 30 min |
| Average detention rate | 40 EUR/h | 40 EUR/h |
| Annual detention fees | 180,000 EUR | 12,000 EUR |
| Dock utilisation | 58% | 74% |
| Calls to the gatehouse per day | 140 | 35 |
Better dock utilisation also lets you postpone building extra docks, an investment of 60,000 to 120,000 EUR per dock leveller.
Budget, timeline and integration
| Scope | Price excl. tax | Timeline | Content |
|---|---|---|---|
| Core: booking, slots, SMS | 20,000 to 26,000 EUR | 6 to 8 weeks | 1 site, simple rules |
| Standard: + goods rules, check-in, WMS | 28,000 to 36,000 EUR | 10 weeks | 1 site, 20 to 40 docks |
| Advanced: + multi-site, plate recognition, carrier API | 38,000 to 45,000 EUR | 12 to 14 weeks | Warehouse network |
| SMS (France) | 0.05 to 0.08 EUR/SMS | Ongoing | About 1,500 EUR/year |
| Maintenance and hosting | 350 to 800 EUR/month | Ongoing | All |
| Off-the-shelf solution (benchmark) | 400 to 1,500 EUR/month per site | 4 to 6 weeks | Standard processes |
Off-the-shelf solutions fit standard processes. Custom becomes relevant with a specific WMS, port flows (containers arriving at unpredictable times) or complex per-client rules. The WMS connector accounts for 5,000 to 10,000 EUR excl. tax depending on whether the WMS exposes an API or flat files.
Mini case study
Sophie, director of a 40,000 m² logistics warehouse in Marseille, receives 80 trucks a day and pays 180,000 EUR a year in detention fees. She picks the standard scope at 34,000 EUR excl. tax, plus 600 EUR a month for maintenance and 1,500 EUR of SMS.

- Detention fees avoided: 180,000 - 12,000 = 168,000 EUR/year
- Gatehouse time freed: 105 calls × 3 min × 250 days = 1,310 hours, or 39,000 EUR/year at 30 EUR/h
- Year 1 cost: 34,000 + 7,200 + 1,500 = 42,700 EUR
Payback: under 3 months. Even if only half of the fees were actually billed, the project would still pay back in under 6 months.
FAQ
Will carriers play along?
Yes, when slots are honoured: a carrier saving 1 h 30 per delivery has every reason to. Set a clear rule, for example 30 minutes of tolerance, and a priority lane for kept appointments. Adoption exceeds 80% after 2 months.
What about trucks without an appointment?
They are still accepted on buffer slots (10 to 15% of capacity) or at the end of the day. The platform measures their share to reduce it over time.
Do we need a kiosk at the gate?
No, a tablet at the gatehouse is enough (300 to 600 EUR). An outdoor kiosk costs 3,000 to 6,000 EUR and a plate recognition camera 2,500 to 5,000 EUR.
How do we handle port containers?
With flexible slots and an alert as soon as the container leaves the terminal, based on data from the freight forwarder. Budget 4,000 to 8,000 EUR for this integration.
Is driver data protected?
Only name, phone and plate are collected, kept for 12 months at most, with EU hosting compliant with GDPR.
