Vacation Rental Owner Portal with Dynamic Pricing & Guest Messaging

Problem and target customer

Why this exists

Customer problem

Short-term rental hosts juggle calendar availability across platforms, manually adjust nightly rates, respond to repetitive guest questions, and coordinate cleaning crews through separate tools or spreadsheets—leading to double-bookings, underpriced nights, slow response times, and missed cleanings.

Who pays

Independent vacation rental hosts managing 2–20 properties who need operational control without enterprise PMS complexity.

Business model

Monthly SaaS subscription tiered by property count, with usage-based add-ons for LLM-generated guest messages and dynamic pricing recalculations.

Editorial note

This portal targets independent hosts managing a small portfolio of vacation rentals who are underserved by enterprise PMS platforms. The MVP narrows scope to one workflow: sync availability, adjust pricing, respond to guests, and dispatch cleanings.

Dynamic pricing stays rule-based rather than algorithmic to keep the MVP transparent and auditable. Hosts approve rate changes before they propagate, preventing unexpected underpricing during the pilot phase.

Guest messaging uses an LLM only for drafting replies from property context—not for autonomous sending. This reduces manual typing by an estimated 70% while keeping the host in control of every guest interaction.

Product goal

Who it serves and what it must change

Target user: Independent vacation rental host managing 2-20 short-term rental properties
Problem: Hosts manually sync calendars, adjust rates, respond to repetitive guest questions, and coordinate cleaning crews across disconnected tools
Measurable outcome: Reduce manual messaging time by 70% and pricing adjustment time by 50% within 30 days of active use

Core entity outline

Entities and business rules

Property

Represents a vacation rental listing with base rate and iCal source

Fields: id, host_id, name, base_nightly_rate, cleaning_fee, min_stay_nights, ical_feed_url, status
Relations: has many Bookings, has many PricingRules, has many CleaningTasks

Booking

A reservation synced from external calendar with check-in and check-out dates

Fields: id, property_id, external_id, guest_name, check_in, check_out, source, status
Relations: belongs to Property, has one CleaningTask

PricingRule

A host-configured rule that adjusts nightly rates based on conditions

Fields: id, property_id, rule_type, condition_value, adjustment_type, adjustment_value, status
Relations: belongs to Property

GuestMessage

An inbound guest inquiry and the drafted or sent response

Fields: id, property_id, guest_name, guest_email, body, draft_body, status, created_at
Relations: belongs to Property

CleaningTask

A cleaning job linked to a booking checkout with crew assignment

Fields: id, booking_id, property_id, assigned_crew, scheduled_date, access_code, status
Relations: belongs to Booking, belongs to Property

Business rules

Nightly rate cannot fall below 50% of base rate without explicit host approval
iCal sync conflicts must be flagged and require host resolution before accepting new availability
LLM-drafted replies must include property name and check-in details from booking data when available
Cleaning tasks auto-create only for confirmed bookings with a checkout date within 7 days
A property cannot be set to active without a valid iCal feed URL and base nightly rate

Architecture and data flow

Components, integrations, and controls

Dashboard Web App

Renders property dashboard, calendar, pricing config, inbox, and cleaning dispatch UI with auth

Pricing Engine Service

Computes nightly rates from base rate and approved pricing rules, flags outliers

LLM Drafting Service

Generates guest reply drafts from property context and conversation history via OpenAI

iCal Sync Worker

Polls external iCal feeds on schedule and updates booking availability in Postgres

Integrations

iCal feed import from Airbnb, VRBO, and Booking.com calendar URLs
OpenAI API for guest message draft generation
Supabase Postgres for all persistent data with row-level security per host
Make for scheduled iCal polling and webhook-triggered cleaning task creation

Data flow

iCal feed parsed by Make scenario → booking records upserted in Postgres
Host configures pricing rules in dashboard → stored in Postgres → pricing engine computes rates
Guest message webhook → stored in Postgres → LLM drafting service generates draft → host edits in UI
Booking status changes to checked_out → cleaning task auto-created → crew notified via Make

Failure handling

iCal feed unreachable → log error, retain last known availability, surface sync warning in dashboard
OpenAI API timeout → return empty draft with manual compose fallback in inbox
Pricing rule produces rate below floor → block application and flag for host review
Cleaning task assignment fails → retry once, then alert host via dashboard notification

Security

Row-level security on all tables scoped to host_id from Supabase auth
Property access codes stored encrypted at rest and only revealed to assigned crew
LLM API key stored as Railway environment variable, never exposed to frontend
iCal feed URLs validated and sanitized before import

Rate limits

iCal sync limited to one poll per property every 15 minutes
LLM drafting limited to 50 message drafts per host per day
Pricing recalculation limited to 10 runs per property per day

Deliverables and acceptance

Definition of done for the MVP

Deliverables

Multi-property dashboard with iCal calendar sync and conflict detection
Rule-based dynamic pricing engine with host approval workflow
Guest message inbox with LLM-drafted replies and manual edit before send
Cleaning task dispatch with crew assignment and completion tracking
Host authentication via Supabase with row-level security

Acceptance criteria

Given a property with a valid iCal feed, when sync runs, then booked nights appear on the calendar within 15 minutes of the external change
Given a base rate of $200 and a 20% weekend premium rule, when the engine runs for a Friday night, then the suggested rate is $240 and requires host approval before applying
Given an inbound guest message asking about check-in time, when the LLM drafting service runs, then the draft includes the property check-in time from booking data and the host can edit before sending
Given a confirmed booking with checkout in 3 days, when the booking status updates, then a cleaning task is auto-created with property access details and assigned crew
Given two hosts in the system, when host A queries properties, then only host A's properties are returned via row-level security

Recommended stack

Enough technology for the first version

Frontend

Lovable

Rapid build of property dashboard, calendar views, and messaging inbox with Supabase auth.

Database

Supabase Postgres

Stores properties, bookings, pricing rules, messages, and cleaning tasks with row-level security per host.

Automation glue

Make

Scheduled iCal polling, webhook triggers for new messages, and cleaning task notifications.

Backend hosting

Railway

Hosts the pricing engine and LLM message-drafting service as containerized workers.

LLM

OpenAI API

Generates context-aware guest reply drafts from property details and conversation history.

Why this is sufficient

Lovable handles the dashboard UI with built-in Supabase auth. Railway runs the pricing calculation and LLM drafting logic as separate services. Make bridges external iCal feeds and message webhooks without building custom polling infrastructure.
