The verdict in three sentences
For a chain of 6 gyms and 7,500 members in Tunis, an international SaaS costs 10,800 to 28,800 TND a year, while custom software requires 90,000 to 180,000 TND upfront. Custom makes sense when you need local payment methods, multi-site access control and automated follow-ups tuned to your members' behaviour, which is also the case for chains in Dubai or the UK with specific hardware or payment setups. The financial stake is not the software: it is bringing churn from 18% to 12%, or keeping 450 members every year.
Where members go
The founder of a chain with sites in Les Berges du Lac, La Marsa, Ennasr, El Menzah, El Manar and Ben Arous currently runs memberships in a local point-of-sale system and spreadsheets. Nobody notices a member hasn't come in for three weeks, renewals happen at the front desk and the turnstiles are connected to nothing.
| Churn reason (internal estimate) | Share of leavers | Software lever |
|---|---|---|
| Undetected drop in attendance | 35% | Alert after 10 days without a visit, coach text |
| Forgotten renewal or failed payment | 20% | Reminders D-7, D-1, D+3 and online payment |
| Moving house or neighbourhood | 15% | One-click transfer between gyms |
| Full group classes | 12% | Class booking and waiting list |
| Price seen as too high | 10% | Off-peak plans, membership freeze |
| Other | 8% | Automatic exit survey |
International SaaS or custom software
International club management platforms are complete but designed for Europe and North America: SEPA or card direct debit, English-first interfaces, turnstile connectors limited to certain brands. Custom software starts from your local reality.
| Criterion | International SaaS | Custom software |
|---|---|---|
| 2026 cost | 150 to 400 TND per gym per month | 90,000 to 180,000 TND + 1,500 to 3,500 TND monthly maintenance |
| 3-year cost (6 gyms) | 32,400 to 86,400 TND | 144,000 to 306,000 TND |
| Local payments (local debit card, mobile wallet, cash) | Partial, mostly international cards | Built in from the start |
| Access control (turnstiles, QR code) | Depends on compatible brands | Connected to your existing hardware |
| Member app in Arabic and French | Rarely in Arabic | Bilingual with RTL support |
| SMS and WhatsApp reminders | Paid add-ons, international SMS | Local carriers, local cost |
| Data ownership | Vendor | You, local hosting possible |
| Timeline | 2 to 4 weeks | 4 to 6 months |
Over 3 years, SaaS remains cheaper. Custom pays back only if it does better on retention, which requires reminders and a member app people actually use.

| Member app (iOS, Android) | Class booking, digital card, progress | 25,000 to 50,000 TND |
| Reminders and retention | SMS, WhatsApp, email flows based on attendance | 8,000 to 18,000 TND |
| Chain dashboard | Revenue, churn rate per gym | 10,000 to 22,000 TND |
Mini case study
Sami, founder of a 6-gym chain in Tunis, has 7,500 members paying an average 85 TND a month. At 18% churn he loses 1,350 members a year. Cutting that rate to 12% keeps 450, or 450 x 85 x 12 = 459,000 TND of annual revenue retained.

He invests 140,000 TND in custom software with a member app, plus 2,500 TND monthly maintenance. Even if only half the target is reached (225 members kept, 229,500 TND), the project pays back in under 9 months.
FAQ
Does an international SaaS work in Tunisia?
Yes for member management, at 150 to 400 TND per gym per month. The limits are local payment methods, Arabic language support and compatibility with some turnstiles.
Can we reuse our current turnstiles?
In most cases yes, if they accept relay or API control. Connecting them costs 1,500 to 3,000 TND per gym, versus 8,000 to 15,000 TND for a new turnstile.
How does software reduce churn?
By spotting members who stop coming (10 days without a visit) and triggering a personalised reminder. Chains that apply it gain 4 to 6 retention points a year.
How much do reminder texts cost?
With a Tunisian carrier, allow 0.04 to 0.08 TND per SMS. 20,000 reminders a year cost 800 to 1,600 TND.
Can member data stay in the country?
Yes, with local hosting compliant with Tunisia's 2004 data protection law and a filing with the national authority (INPDP). In the UK or the UAE, the same logic applies under UK GDPR or the UAE data protection law.
