NextPax vs Rentals United vs Smoobu

• Follow the setup guide to link your Airbnb account. Your property-management software or Supply API controls where the data comes from.

• Airbnb receives listing details on its own or when you request an update. Prices and open dates update when a change is recorded. Rentals United receives Airbnb bookings. Change or cancel bookings in Airbnb. Your settings control which details update.

• Link your Airbnb account and match its listings to Smoobu properties. Smoobu sends prices and open dates. It receives bookings and cancellations.

• Follow the partner setup steps and meet Vrbo’s listing and payment rules. The Americas FAQ explains how bookings are handled.

• Vrbo collects listing changes once in 24 hours. Prices, open dates and available units update on their own; Vrbo also collects them daily. New bookings are sent through the connection. Changes and cancellations go both ways under Vrbo’s rules.

Details: Vrbo iCal

• Vrbo, FeWo-direkt and Abritel use two iCal calendar links. Set prices and stay rules on Vrbo. Imports usually take 10–20 minutes. Vrbo may take up to 24 hours to collect updates.

• Follow the Booking.com setup guide. Match its price plans, stay rules and listing details.

• Booking.com sends bookings and changes to Rentals United. You can also change or cancel there, with some limits. Both single-unit and multi-unit properties can connect.

• Connect each Booking.com property and match its rooms and price plans. Use Smoobu to send prices and open dates.

• NextPax lists sites beyond Airbnb, Vrbo and Booking.com. Check each site’s rules. Links to global travel-agent systems (GDS) cost extra.

• Rentals United lists other booking sites too. Check each site’s connection guide for what it can share.

• Other booking sites use direct connections or iCal calendar links. What you can share depends on the connection. iCal shares open and booked dates only.

• Supported property software shares bookings, open dates, prices and listing details both ways. White Label Supply API connects your own system. These links share more than calendar dates.

• One service sends updates, or the other checks for them. The direction and method depend on the booking site and data.

• Direct links work both ways. Each iCal calendar link works one way, so set up both import and export. Add existing outside bookings during setup. Set up the first price update too.

• Set multiple price plans and policies, plus price increases for each site. Booking.com policy overrides are listed too. Extra charges must use fields that the booking site supports.

• Airbnb prices, open dates and available units update when a change is recorded. Vrbo receives updates and also collects them daily. Check how each site matches listing details and amenities.

• Smoobu sends prices and open dates through direct connections. Some settings stay on the booking site. The Vrbo iCal link does not send prices.

• The property-software and Supply API links share bookings. Rules for changes depend on each booking site.

• Vrbo booking changes go both ways. Changes made in Rentals United for Booking.com have limits. Follow the separate steps to transfer a booking to Vrbo.

• Bookings and cancellations from connected sites appear in one calendar. You must add or import bookings from other sources.

Details: White Label API

• The Supply API price table says updates happen in real time. This covers dates, prices, listings, messages, reviews, offers and bookings. Actual speed is not confirmed.

• Airbnb prices, open dates and available units update when a change is recorded. Vrbo collects listing details once per 24 hours. Its prices, open dates and available units update on their own, with daily collection too. Do not assume every update is instant.

Details: Supported PMS; White Label API

• Pro, Scale and Enterprise list Unified Inbox. Check which message types each booking site supports.

• Paid plans list guest messaging in one place. A calendar-only link does not confirm that you can send messages through that site.

Details: Supported PMS; White Label API

• The plans list guest messaging. We could not confirm which events send messages or each booking site’s sending limits.

Details: White Label API

• White Label API connects your own system. Supported PMS is a separate option. Check whether your plan includes Promotions API.

Plan: Enterprise

• Enterprise lists a direct API connection for your software. We could not confirm direct API access for Pro or Scale.

• Developers can use an API key and receive automatic updates called webhooks. Ask support to allow API keys during a trial. The HMAC guide explains how to sign requests. Only the from/to booking-date filters currently work.

• Both plans target 50+ units or rooms. The $350 monthly minimum covers the first 50. Ask whether smaller accounts qualify. We could not confirm a firm minimum or maximum account size.

• Pro targets 10–50 listings, Scale 50–200 and Enterprise 200+. These ranges describe intended users. We could not confirm hard property limits.

• Ask for a price above 20 properties. We could not confirm a maximum number of properties per account.

• The USD $350 monthly minimum includes the first 50 units/rooms. Extra units are advertised at $4 monthly or a $3.60 monthly equivalent on yearly billing. It is unclear if the minimum also gets the yearly discount.

• Pro starts at $330 per account, not per property. Your bill may be higher. Screen & Protect, Website Builder, Elevate and Google Redirects cost extra.

• Flex charges 0.9% on connected-site and Booking Engine bookings. Users who can make changes cost €15/month, with no yearly discount. Read-only access is free. Check the billing currency; displayed conversions may differ. Smoobu’s guides disagree on website booking fees. The Flex guide says 0.9%, so check your agreement.

• Plans list one-to-one setup help and chat, email and phone support. Some plan details mention priority support. Check what your agreement includes.

• Pro lists a setup offer. Scale lists a setup expert, account manager and priority support. Enterprise adds technical and planning help. Ask who qualifies and get a quote for the full cost.
