The verdict in three sentences
A B2B booking portal for an equipment rental company runs between 22,000 and 48,000 EUR in 2026. It shows real-time availability by fleet and branch, automatically generates contract, deposit and payment, and eliminates both double bookings and an overloaded phone line. The economic stake: recovering fleet utilization and counter-staff time.
What the budget covers
The core is availability management: each machine has a calendar, a status (available, booked, in maintenance) and a branch. Add online booking, e-contract, deposit and payment capture.
| Module | 2026 range (EUR) | Timeline |
|---|---|---|
| Fleet catalog & availability | 6,000 - 12,000 | 4-6 weeks |
| Booking engine & calendar | 5,000 - 11,000 | 4-6 weeks |
| E-contract & signature | 3,000 - 7,000 | 2-4 weeks |
| Deposit & online payment | 4,000 - 9,000 | 3-5 weeks |
| Client area & history | 4,000 - 9,000 | 3-5 weeks |
| Total project | 22,000 - 48,000 | 4-6 months |
Custom portal vs standard rental software
Rental management software exists, often back-office oriented. A custom portal is justified when you want to open booking directly to your professional clients with your own experience.
| Criterion | Rental SaaS | Custom portal |
|---|---|---|
| Upfront cost | 3,000 - 10,000 EUR | 22,000 - 48,000 EUR |
| Online client booking | Often absent | Native |
| Real-time client availability | Rare | Yes |
| Your-brand experience | Limited | Total |
| Recurring cost | 200 - 800 EUR/mo | Hosting only |
| Timeline | 1-3 months | 4-6 months |

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Nadia, director of a construction equipment rental company in Miami with 3 branches, receives about 900 calls/month requesting availability, 60% of which could be handled online. Each call takes 6 minutes of a counter agent: 90 hours/month at a 32 EUR loaded cost, i.e. 2,880 EUR/month. Shifting 60% to the portal saves 1,730 EUR/month of counter time, plus ending double bookings estimated at 4/month (about 1,200 EUR lost revenue). On a 38,000 EUR project, payback is around 13 months.
FAQ
How does the portal avoid double bookings? Each machine has a single locked calendar: as soon as a slot is booked and paid, it becomes unavailable in real time across all channels. No more gap between counter and phone.
Can the deposit be handled automatically? Yes, via a card pre-authorization or a deposit captured then released on return. This module is 4,000 to 9,000 EUR depending on the payment provider.
Do our pro clients need an account? Recommended: a client area with history, contracts and invoices speeds up recurring bookings. It is also what sets you apart from a simple form.
How long to go live? 4 to 6 months for a full portal. A first version with catalog and booking request (no payment) can ship in 8 to 10 weeks for about 16,000 EUR.
What maintenance budget? 15 to 18% of build cost per year, i.e. 3,500 to 8,500 EUR, covering hosting, security updates and fleet changes.
