The Decision

Choosing the right upselling software can dramatically impact your hotel's revenue and guest experience. Both Plusgrade and SiteMinder Guest Engagement aim to increase ancillary revenue through pre- and during-stay offers, but they diverge in focus, features, and market presence.

Plusgrade specializes in automated upgrade transactions, mostly focusing on room and suite upgrades, leveraging proprietary bid systems. SiteMinder, meanwhile, offers a broad suite of add-ons and personalized offers across multiple channels with extensive automation and guest engagement tools.

Plusgrade’s strength lies in its automation and proven revenue results in upscale markets, while SiteMinder’s versatility and extensive integrations support diverse hotel segments. Are you prioritizing automation or customization?
