Feature Comparison Summary
Bokun pulls Viator, Google Things to Do, and 2,600-plus resellers into one dashboard for tour and activity operators. Availability syncs automatically, and the free plan plus 14-day trial keep the risk low. Overall, it's a recommendable pick for operators who'll budget for the per-booking fees.
Notify Me! turns sold-out pages into waitlists, pre-orders, and wishlists, then feeds demand signals into Klaviyo, Mailchimp, Omnisend, and PushOwl. Its 4.9/5 rating across 3,400-plus reviews shows real recovery power, but it's locked to Shopify and BigCommerce and SMS costs vary by country. Overall, it's a strong pick for stores losing sales to stockouts.
Bokun is booking management software for tour and activity providers. It's owned by Tripadvisor, the same company behind Viator. The platform lets operators take direct bookings on their own website, sync availability across sales channels, and connect to a marketplace of resellers and OTAs. It serves tour operators, attractions, activity companies, rental providers, destinations and DMOs, ground transport businesses, and resellers.
Notify Me! is a Shopify and BigCommerce app that turns out-of-stock moments into revenue. It replaces "Sold out" buttons with waitlist signups, preorder options, and wishlists, then feeds those signals into your email and marketing tools. It's built for e-commerce merchants who want to capture demand on products they can't currently ship—from small brands to the 35,000+ stores already using it.
