Group Booking App

GroupTravel solves the #1 pain in large-group holidays — one person fronting thousands and chasing repayments — by requiring 100% payment commitment before any booking is made. Think Doodle + Splitwise + escrow, but purpose-built for villas & group accommodations.

The app addresses the uneven financial burden and awkward “pay me back” dance in group settings. It removes this burden from any single individual by requiring unanimous payment commitment upfront. This ensures the booking only proceeds once everyone has formally pledged. The commitment mechanism builds accountability — people are far more likely to follow through when they’ve already authorized payment, compared to verbal promises that often lead to ghosting.

Key Features

App Flow

1. Create Group → Set rules & constraints
2. Propose Accommodations
3. Time-bound Vote → Winner selected
4. Pledge Stage (pre-auth / hold) → 100% threshold?
   • Yes → Auto-charge & Book & Pay (or provide booking link)
   • No → Time expires → Proposal cancelled / reset

The app flow consists of five key stages: Create, Propose, Vote, Pledge, Book & Pay. Each stage has a distinct purpose and mechanic.

Create stage

Users create a group by inviting friends and family (via shareable link or email). The group can be named and includes a built-in chat. The group admin sets key constraints: destination region (country or continent), budget range, and travel dates (specific or flexible). Nice-to-have: Ability to deep-link or export the group to an existing WhatsApp group so members can continue chatting there instead of in the app.

Propose stage

Any member can propose a place (villa, large house, hotel, etc.) that fits the group’s constraints.

Vote stage

Everyone votes for their favourite option within a time-bound window (e.g. 48–72 hours). Members can vote or pass. The option with the most votes advances. In case of a tie:

• First re-vote between tied options
• If still tied, the winner is decided by the admin’s pre-set tiebreaker rule (e.g. cheapest, cheapest average flights, shortest flight time, or admin’s choice)

Pledge stage

Once a place wins, every member must pledge their share by providing payment details and authorizing a hold (pre-authorization) on their card — no money is taken at this point. Members can pledge for themselves or multiple people (e.g. you and your partner). A countdown timer enforces a decision window (e.g. 48–72 hours).

• If 100% of required spots are pledged → the app automatically charges all participants and proceeds to book the accommodation (via integrated API or by providing the admin with a confirmed booking link).
• If the time window expires or someone withdraws their pledge → all pre-authorizations are released and no charges occur. This is the final opportunity to back out before any money is taken. After full commitment and charging, cancellations follow the group’s refund rules.

Admin privileges

The group admin can:

• Cancel the trip before full pledge
• Set a minimum commitment threshold (e.g. 80% of spots) — if not reached, the trip returns to the proposal stage
• Kick individual members from the group
• Pause or extend voting/pledge windows if needed

Flights

The app does not book flights (too many variables: checked bags, seat selection, different departure cities, etc.). Instead, it displays real-time aggregated flight options and prices for the chosen departure and return dates (via APIs like Skyscanner or Google Flights). Once accommodation is locked, individuals book their own flights. Future potential: Suggest optimal dates based on the cheapest average round-trip flight prices.

Why

Why group booking via the app is often better than everyone booking separately?

While individual bookings can sometimes be simpler or cheaper (especially for small groups or flexible travellers), large-group travel frequently creates situations where trying to book separately becomes impractical, significantly more expensive, or delivers a much poorer shared experience. The app is purpose-built for the scenarios where staying together provides clear advantages.

Key reasons group booking usually wins for larger groups (8+ people):

• Fixed pricing and minimum occupancy requirements
  Many villas, chalets, large houses, and group accommodations are priced as a single unit (e.g. €4,000–€10,000 per week), not per person or per bedroom. If only 5–7 people try to book individually or in smaller sub-groups, the property will either reject the booking or charge nearly the full rate anyway — dramatically increasing the cost per person.

• Group discounts and exclusive availability
  Villa owners, boutique hotels, and private rentals often offer meaningful discounts (10–30%) or special perks (free chef night, welcome package, late check-out, private boat) only when the entire property is booked by one group. These benefits disappear completely when the group splits.

• Shared amenities become uneconomical or unavailable when fragmented
  The true value of a large group property often lies in facilities that only make sense when shared:

  • Private pool, hot tub, games room, home cinema
  • On-site chef, private yoga sessions, boat rental, or driver
  • Expansive communal dining, living, and outdoor spaces designed for 10–16 people

• Social and logistical cohesion suffers when scattered
  Groups usually want to spend the holiday together. Booking different places creates constant friction: misaligned times, split meals/activities, endless coordination, and some members feeling left out of the main experience.

• Fragmented booking increases chaos, cost volatility, and decision fatigue
  Different cancellation policies, price changes, repeated “who’s paying what” talks, and inconsistent deals make planning painful. The app’s unified process secures one price and reduces switching between apps.

In short
Individual booking works for small or independent groups.
For larger groups who want to stay together in a villa or large rental — the core use case — separate booking usually leads to higher costs, fewer options, lost discounts, and a fragmented experience.
The app removes the biggest barrier (one person fronting everything) while unlocking the financial, logistical, and emotional benefits of group stays.

Challenges

1. Booking timelines and availability
   Travel deals and availability can disappear quickly. Waiting for 10+ people may cause the chosen property to become unavailable.
   Mitigation: Time-bound pledge windows (48–72 hours) + temporary holds/reservations where providers allow it (many APIs support this). If holds aren’t possible, show estimated prices with clear warnings and allow quick re-voting.

2. Payment logistics
   Need secure integration to handle individual pledges without charging until 100% is reached.
   Solution: Pre-authorize cards (no charge), then charge everyone simultaneously when the threshold is met. Automatic release of holds if the group doesn’t complete.

3. Group dynamics
   Need clear rules around commitments, withdrawals, and dropouts to prevent friction.
   Data privacy (GDPR/CCPA) and payment regulations must be strictly followed.

4. Better than WhatsApp + Splitwise + manual booking?
   WhatsApp groups often lead to ghosting, long delays, and escalating costs. The app counters this with time-bound voting/pledge windows and a mostly end-to-end experience (except flights), greatly reducing app-switching and decision paralysis.

Misc

Cancellation & Refund Policy (Provisional)

• Before 100% pledge: Anyone can withdraw their pledge. Pre-authorizations are released automatically — no penalty.
• After 100% pledge and charging:
  • Cancellations follow the accommodation provider’s policy (accessed via API or manual link).
  • The app does not offer refunds beyond what the provider allows.
  • If some users cancel post-charging: remaining members may face a higher per-person cost (if provider adjusts for lower occupancy) or the booking may be cancelled entirely.
  • Admin can poll the group to absorb increased costs or restart the proposal process.
• If booking fails after charging (e.g. provider error): The app assists with refunds via the provider / Stripe Connect but is not primarily liable (see Legal section).

This policy will be finalized after selecting the primary booking API and legal review.

Monetization Strategy

• Initial phase: No transaction fees during development and early testing.
• Planned model: Small transaction fee (1–2%) on successful bookings.
• Future options:
  • Freemium (basic groups free, premium for larger groups, advanced polls, AI suggestions, priority support)
  • Affiliate commissions from displayed flights and accommodations
  • Premium features (e.g. custom group branding, enhanced reminders)

Validation Plan

We will measure success using:

• Number of group holidays successfully booked through the app
• Percentage of created groups that reach 100% pledge
• Average time from group creation to full pledge
• Re-use rate: how many people/groups return to book another holiday
• User feedback: NPS and “would use again” responses from completed trips

Legal & Compliance Considerations

Operating a group travel booking app that handles payment commitments, pre-authorizations, and eventual charges involves several important legal and regulatory obligations.

1. Payment Services Compliance

• PCI DSS: No direct storage, processing or transmission of full card details. All card handling outsourced to a certified provider (e.g. Stripe).
• Strong Customer Authentication (SCA) / PSD2: Full support for 3D Secure 2.0 in EEA/UK markets.
• Other: GDPR/UK GDPR/CCPA, AML screening where required, consumer protection laws.

2. Merchant of Record (MoR)

Recommended model: Stripe Connect with the accommodation provider (villa owner/property manager) as the connected merchant of record.

• The app acts as a facilitator/platform.
• Reduces direct liability for failed bookings, tax obligations, and chargebacks.
• Users see charges from the actual provider (more transparent).

3. Liability if the Booking Fails After Everyone Has Paid

• The app is not the accommodation provider — it acts only as a facilitator.
• Primary liability rests with the property owner/provider.
• If the booking fails due to provider error: the app assists users in obtaining refunds via Stripe Connect or direct contact.
• The app is not financially liable beyond reasonable assistance unless gross negligence is proven.
• Users are encouraged to purchase travel insurance covering provider default.
  These limitations must be clearly stated in the Terms of Service and during payment.

4. Terms of Service – Binding Commitments

• Pledge / pre-authorization: Becomes binding once the group reaches 100%. Users agree their card will be charged the agreed amount.
• Before 100%: Withdrawal allowed — pre-auth released automatically.
• After charging: Cancellations subject to provider’s policy. App does not offer refunds beyond what provider allows.
• Price changes: If members drop out post-commitment, remaining participants may face higher per-person costs.
• Disclosure: Users must explicitly acknowledge understanding of binding commitments and cancellation rules (via checkbox/button).
• Dispute resolution: Governing law (country of incorporation) + preferred method (arbitration or courts).

Important: Final Terms of Service, Privacy Policy, and payment disclosures must be reviewed and customized by a qualified lawyer before launch.
