Reservation Management

The online reservation system that runs itself.

Not a calendar widget. A complete reservation management system — for properties, vehicles, rooms, tables and spaces. Every confirmed reservation auto-invoices, holds the deposit, logs a CRM activity, and manages check-in and check-out automatically.

The problem

Your reservation lives in one system. Everything else lives somewhere else.

A guest makes a reservation on your website — someone retypes it into the accounting tool for the invoice. Someone else logs it in the CRM. A third person sets a reminder for check-in. A fourth chases the deposit. When they check out, it starts again.

Most reservation software handles the calendar and ignores the other eight steps. Reservation365 handles them all from the moment the reservation is confirmed.

How it works

One confirmed reservation. Six things happen automatically.

The moment a reservation is confirmed, Reservation365 writes the result into every part of your business — accounting, CRM, operations — without anyone touching a keyboard.

Reservation #RSV-7214 confirmed Villa Rosa · Müller family · Jun 24 – Jul 1 · €1,820 + €400 deposit

Invoice raised

Posted to Accounting immediately. Status tracks from draft → sent → paid as payment is collected.

Deposit held

Refundable deposit is captured and tracked. Released or forfeited at check-out according to your configured rules — no manual step.

CRM activity logged

The guest record is updated and follow-up tasks are assigned to the right team member automatically.

Calendar blocked

Resource availability updates in real time across every channel — admin, portal, widget and API. No double-bookings possible.

Confirmations sent

Guest confirmation email, pre-arrival instructions and check-in reminder go out on the schedule you configure.

Check-in & check-out

Actual timestamps are captured and used for accurate time-based billing and deposit settlement at the end of the stay.

When a cancellation happens, the cancellation policy runs in code — not in a customer-service apology. Forfeit rules, grace periods and partial refunds are configured once and enforced automatically every time.

Universal reservation engine

One reservation model. Five resource types.

A villa, a meeting room, a rental car, a restaurant table and a mooring berth are the same record type — with different resources and pricing rules attached. No vertical add-ons. No separate systems.

Properties & accommodation

Villas, apartments, holiday rentals and serviced rooms — with nightly rates, per-person pricing, minimum stays and refundable damage deposits.

Vehicles & fleet

Rental cars, boats, motorhomes and specialist vehicles — with availability by unit, daily rates, extras, handover checklists and deposit handling.

Rooms & spaces

Hotel rooms, meeting rooms, event halls, training rooms and coworking desks — with capacity rules, setup buffers and equipment dependencies.

Tables & dining

Restaurant and café tables — with party-size validation, session lengths, no-show enforcement and configurable cancellation policies.

Equipment & assets

Ski lockers, storage units, mooring berths, sports facilities — any reservable asset, with the same lifecycle and billing engine.

Custom resource types

The resource model is open. Define your own type with its own availability rules, pricing and deposit behaviour — no code needed.

Availability & channels

Real-time availability across every channel

Availability is computed from a single source of truth. When a reservation is confirmed on any channel, every other channel sees it blocked immediately. Double-bookings don't happen because they can't.

  • Multi-channel sync admin, guest portal, embeddable widget and API all read from one engine in real time
  • Flexible pricing nightly, weekly, seasonal, per-person, extras and promotions — configured in one place, applied everywhere
  • Minimum stay & advance limits enforce minimum nights, booking windows and blackout periods without manual intervention
  • Automatic alternatives when a resource is unavailable, the system suggests the next available slot or a similar resource

Actual check-in and check-out timestamps drive accurate billing for time-based rates. Deposit release rules, grace periods and partial refunds are configured once per resource type and enforced automatically on every reservation.

Built for every reservation business

If you take reservations, Reservation365 runs it.

The same reservation engine handles nights, days, hours and slots — for properties, restaurants, fleets and spaces. One system, every industry.

Hospitality & holiday rentals

Hotels, guesthouses, villas and vacation rentals — with nightly pricing, seasonal rates, cleaning fees and guest check-in automation.

Restaurants & dining

Table reservation management with party-size controls, deposit requirements on larger parties and automatic no-show handling.

Vehicle & equipment rental

Car hire, boat rental and specialist equipment — with per-day pricing, handover checklists, deposit capture and fleet availability tracking.

Event & meeting spaces

Conference centres, event halls, coworking spaces and private-hire venues — with setup times, catering add-ons and capacity rules.

Sports & recreation

Tennis courts, golf tees, marina berths, spa treatments — with capacity limits, member priority and cancellation policies.

Property & real estate

Short-term rentals, viewing appointments and lease reservations — with automated confirmation workflows and integrated invoicing.

Rental marketplaces

Two-sided platforms with host and guest flows, platform fee calculation, direct payouts and two-sided post-stay reviews.

Any reservation business

If you reserve a resource over time — nights, days or hours — the Reservation365 engine handles it. The model is open and fully configurable.

The business case

What manual reservation admin actually costs

Conservative figures for a 20-property rental operation. Before counting revenue recovered from no-shows and faster deposit handling.

€6–18k
Replace the reservation tool

At €25–75 per property per month for a typical reservation SaaS subscription, per year.

€10k
Eliminate manual invoicing

300 reservations a month at 5 minutes each to raise and send invoices — 300 hours/year at €35/hour.

€7k
Recover no-show revenue

Automatic cancellation enforcement and deposit forfeiture recovers revenue that previously slipped through with a manual apology.

€23–35krecovered in year one

Hard-dollar savings for a mid-sized reservation business — plus eliminated double-bookings, 24/7 guest self-service, and a CRM that stays current without anyone maintaining it.
