Whether it’s a week in Paris or a month in Lisbon, The Flex makes short stays feel like home.
But as operations scaled across four cities (and counting), so did the complexity of check-ins,
guest comms, ID verification, and upsells. The team needed a unified way to manage
everything — without adding headcount.
That’s where Charge Automation came in. Today, it powers The Flex’s automated check-in
experience across all markets, from remote document signing to seamless payment flows. It’s
become an invisible but essential part of delivering a high-touch guest experience at scale —
and a key enabler of The Flex’s short term apartment rentals model.
Scaling Guest Onboarding — Without Scaling Overhead
As The Flex expanded to Paris, Lisbon, Algiers, and soon Milan, Casablanca, and Cairo, guest
management quickly became a critical pain point.
“We couldn’t manually guide every guest through ID checks, document signing, or upsells,”
says Michael Buggy, Co-Founder of The Flex. “Charge Automation made it possible to scale
our check-in process without scaling our headcount.”
Charge Automation now handles the entire guest flow, from pre-arrival to post-stay, including:
- Digital check-in (ID verification, custom questions)
- Automated document signing
- Upsells and add-ons (e.g., early check-in, parking, cleaning)
- Guest messaging and reminders

Trust and Compliance at Scale
For an international operator, local compliance is no small task. From check-in forms in Paris to
guest identity requirements in Algiers, Charge Automation has enabled The Flex to meet
varying legal standards — without over-engineering their process.
“ChargeAutomation doesn’t just tick boxes — it builds confidence,” says Raouf Yousfi, CEO of The Flex
and Forbes 30 Under 30 honouree. “Guests feel taken care of, owners see our professionalism,
and our team has one less thing to worry about.”
Monetising the Guest Journey
With Charge Automation’s upsell tools, The Flex has also opened new revenue streams:
- Guests opting for early check-in or late check-out
- Add-ons like mid-stay cleaning or extra linen sets are now offered pre-arrival
- Payment flows are smooth, secure, and automatic
“It’s the kind of monetisation that actually adds value,” says Buggy. “Guests appreciate the
flexibility, and we maximise every stay.”

Results That Speak
Since integrating Charge Automation, The Flex has seen:
- Increased guest completion rates for pre-arrival forms
- Massive time savings in check-in support tasks
- Increased add-on revenue from upsells
- Fewer manual errors and follow-ups
For a team growing by 10–20 apartments per month, this automation is mission-critical.
Advice to Growing Operators
Yousfi offers this to other property managers scaling up:
“As you grow, the guest experience either improves or suffers — there’s no neutral. Charge
Automation gives you structure without sacrificing personality. That’s rare in this industry.”
