The verdict in three sentences
For a network of 4 coworking spaces in Lisbon, a custom booking platform at 40,000 to 70,000 EUR pays off once you pass roughly 400 active members. Below that, a SaaS like Nexudus at 3 to 6 EUR per member per month remains the sensible choice, provided it handles MB WAY, Portuguese invoicing and your access control. The real stake is recovering the 15% of lost revenue on meeting rooms, not the software licence.
Where the 15% of meeting room revenue goes
In many Lisbon networks (Avenidas Novas, Cais do Sodré, Parque das Nações, Alcântara), meeting rooms are still booked over WhatsApp, a shared Google Calendar or at the front desk. The result: double bookings, slots blocked and then abandoned, and external clients who give up because they cannot pay online. Across 4 sites with 14 rooms billed at 15 to 40 EUR per hour, the gap between actual occupancy (55% on average) and the 70% target represents meaningful monthly revenue.
| Source of loss | Estimated share of lost revenue | Platform fix |
|---|---|---|
| No-shows without penalty | 35% | Prepayment by card or MB WAY, free cancellation until 4 h before |
| Double bookings and conflicts | 15% | Single real-time calendar across sites |
| External clients without an account | 25% | Guest booking with online payment |
| Slots blocked by members and not used | 15% | Automatic release if no QR check-in within 15 min |
| No dynamic pricing | 10% | Off-peak rates, credit packs |
2026 order of magnitude: across 14 rooms, moving from 55% to 70% occupancy over 10 business hours a day and 22 days a month, at 22 EUR per hour on average, adds about 10,200 EUR of monthly revenue.
Custom build or coworking SaaS: the numbers
Specialist tools (Nexudus, Cobot, OfficeRnD, Optix) usually charge 3 to 6 EUR per member per month, with paid add-ons for rooms, access and billing. Their limits in Portugal: MB WAY is rarely native, certified invoicing under AT rules (ATCUD, QR code on invoices) often needs a third-party connector, and access control depends on certified readers.
| Criterion | Market coworking SaaS | Custom platform |
|---|---|---|
| Upfront cost | 0 to 3,000 EUR (setup) | 40,000 to 70,000 EUR |
| Recurring cost for 500 members | 1,500 to 3,000 EUR/month | 600 to 1,200 EUR/month (hosting + maintenance) |
| Local payments (MB WAY, Multibanco) | Third-party gateway or missing | Native integration |
| QR access control | Imposed partner readers | Dynamic QR on your existing gates |
| Certified invoicing (AT, VAT 23%) | Connector or manual export | Automatic invoices |
| Time to go live | 2 to 6 weeks | 3 months |
| Code and data ownership | No | Yes |
Over 3 years for 500 members, SaaS costs about 54,000 to 108,000 EUR, versus 62,000 to 113,000 EUR for custom (project + operations). Custom wins when you add the revenue recovered on rooms and the freedom to build your own pricing rules; the break-even sits around 400 members.
The functional scope of a 3-month MVP
| Module | Content | Share of budget |
|---|---|---|
| Multi-site catalogue | Rooms, offices, desks, capacity, equipment, photos | 10% |
| Booking engine | Slots, rules per plan, monthly credits, waiting list | 25% |
| Payment and invoicing | Cards, MB WAY, certified invoices, credit notes | 20% |
| Access control | Dynamic QR refreshed every 30 s, entry log | 15% |
| Member web and mobile space (PWA) | Bookings, invoices, guests, notifications | 15% |
| Back office and analytics | Occupancy per room, revenue per site, no-shows | 15% |
Typical schedule: 3 weeks of scoping and mock-ups, 7 weeks of development in sprints, 2 weeks of acceptance testing and site-by-site rollout.

Inês, COO of a 4-site coworking network in Lisbon, manages 520 members and 14 rooms. Her current SaaS costs 5 EUR per member, about 2,600 EUR per month, plus 250 EUR of payment and invoicing connectors. She commissions a custom platform for 58,000 EUR with 900 EUR per month of operations. Recurring saving: 1,950 EUR per month. By lifting room occupancy from 55% to 66% by month six (target 70%), she gains about 7,500 EUR of monthly revenue. The project pays back in under 7 months after go-live.
FAQ
How much does a custom coworking booking platform cost in Lisbon?
Budget 40,000 to 70,000 EUR for a multi-site MVP with local payments and QR access control. Operations (hosting, maintenance, minor changes) then cost 600 to 1,200 EUR per month.
Should we just stay on Nexudus?
Under about 400 members, usually yes: the licence is cheaper than a build. Above that, or if you need custom pricing and native MB WAY, the 3-year total cost favours custom.
Can we keep our current gates and badges?
In about 80% of cases, yes: the platform generates a dynamic QR read by a compatible reader added to the gate, for 200 to 600 EUR per access point.
What meeting room occupancy should we target?
A well-equipped network reaches 65 to 75% over business hours. Above 80%, raise prices or open rooms, or members will complain about missing slots.
How long does migration from an existing SaaS take?
Moving members, contracts and credits takes 1 to 2 weeks within the 3-month project, with a site-by-site switch to avoid any downtime.
