Duve Upselling and Oaky by Plusgrade both aim to increase hotel revenue through upselling but diverge significantly in scope and operational approach. Duve integrates upselling within a broad guest experience platform that includes guest messaging, digital check-in, and third-party marketplace offers. Oaky focuses tightly on automated, segmented upselling campaigns with strong dynamic pricing and gamification features for staff motivation.
Duve suits hotels looking for an all-in-one revenue and guest engagement ecosystem that reduces front desk workload while personalizing communication across multiple channels including WhatsApp and SMS. Oaky fits properties prioritizing streamlined upselling, especially pre-arrival and front desk offers, with data-driven segmentation and automation to maximize ancillary sales.
Both solve the problem of monetizing unsold inventory and enhancing guest spend, but Duve embeds upselling into a wider digital guest journey, whereas Oaky sharpens the upsell process with targeted, automated offers and staff engagement tools.
If you run a hotel that requires a comprehensive guest engagement platform beyond upselling—such as integrated guest messaging, mobile check-in, and a branded guest app—Duve is the better fit. This is supported by Duve’s 31 unique features including WhatsApp integration, mobile checkout, and detailed offer analytics, which are praised by hotel groups like Fattal and Sofitel for improving operational efficiency and guest satisfaction.
If your property’s focus is maximizing upsell revenue through automated, personalized, and segmented offers delivered pre-arrival and at check-in, Oaky is preferable. Oaky’s strong segment ratings for luxury hotels (4.9/5 across 280 reviews) and branded hotels (4.8/5 across 216 reviews), combined with its gamification of front desk upselling and dynamic pricing, point to its suitability for properties that want to empower staff and execute targeted upselling campaigns efficiently.
Data for extended stay and vacation rentals is limited for Oaky, suggesting Duve’s broader feature set and integration capabilities may better serve these segments. Conversely, Oaky’s lack of recent reviews (zero in the last six months versus Duve’s 130) weakens confidence in its current product and support status.
Both products receive high marks for ease of use: Duve scores 4.7/5 and Oaky 4.8/5 on Hotel Tech Report. Reviewers describe Duve’s interface as intuitive and aesthetically pleasing, albeit with a learning curve tied to the platform’s breadth. Oaky users highlight a user-friendly design that facilitates rapid adoption of upselling campaigns without extensive training.
Onboarding ratings are similarly close (4.6/5 Duve, 4.7/5 Oaky), with Duve’s comprehensive training praised but some users noting initial setup complexity due to numerous integrations. Oaky’s onboarding is straightforward but some report a learning curve to master its advanced upselling features.
Hotel staff adoption is supported by Duve’s integrated guest messaging and communication hub that reduces manual workload, helping teams transition more easily. Oaky motivates front desk teams through gamification, driving engagement in upselling efforts.
Edge: Even.
Duve offers 31 unique hotel-relevant features beyond the 12 shared with Oaky, transforming upselling into a multi-channel guest engagement platform. These include WhatsApp integration, SMS messaging, automated replies, mobile check-in/checkout, digital acceptance and payment capture, guest surveys, local recommendations, and an open API for custom integrations. Operationally, this enables front desks and guest services teams to automate communications, accept payments remotely, and tailor upsells by guest profile and loyalty status, enhancing personalization and staff efficiency.
Oaky lacks unique features beyond the shared core upselling capabilities. It focuses on automation, segmentation, and dynamic pricing within its existing feature set, but does not offer additional communication channels or guest apps.
The 31 exclusive features in Duve materially change workflows: for example, automated opt-in and consent collection reduces compliance risks; staff fulfillment visibility and inventory controls improve upsell management; and multi-lingual automatic translations facilitate service in international markets.
Edge: Duve Upselling by Duve.
Oaky leads in customer support and onboarding with ratings of 4.9/5 and 4.7/5 compared to Duve’s 4.6/5 and 4.6/5. Reviewers consistently praise Oaky’s responsiveness and the expertise of its support team, highlighting quick resolution and helpfulness in implementation. Testimonials mention key team members going “above and beyond” and a partnership approach to success.
Duve’s support is described as professional and efficient by many, with account managers like "Gal" singled out for exceptional service. However, 4 of 17 negative Duve reviews mention difficulty reaching support or delayed responses, which could impact hotels during critical setup or issue resolution phases.
Edge: Oaky by Plusgrade.
Duve supports 72 verified integrations, 33% more than Oaky’s 54. Both share 26 common integrations including major PMS providers like Oracle Hospitality, protel, SiteMinder, and Stayntouch.
Duve uniquely integrates with Priority Software, eviivo, WebRezPro, Guesty, SALTO Systems, and others that particularly benefit hotels with diverse PMS needs, vacation rentals, and advanced access control systems. Oaky’s unique partners include ManCloud, Bookboost, hotelkit, and Bookassist, which are more focused on digital marketing and distribution.
Hotels requiring broad PMS compatibility, especially with niche or vacation rental systems, will find Duve’s integration breadth advantageous. Oaky’s partners support its upselling and marketing focus but do not match Duve’s overall ecosystem coverage.
Edge: Duve Upselling by Duve.
Overall ratings are close: Duve 4.6/5 across 449 reviews and Oaky 4.8/5 across 528 reviews. However, Oaky has zero reviews in the last six months compared to Duve’s 130, indicating a 100% drop in recent review activity that may reflect changes not captured in its all-time rating.
Segment-specific ratings favor Oaky in luxury hotels (4.9/5, 280 reviews vs Duve’s 4.7/5, 186 reviews) and branded hotels (4.8/5, 216 vs 4.8/5, 129). Duve leads marginally in vacation rentals and extended stay segments, which have insufficient Oaky reviews for conclusive comparison.
Hostels, city center hotels, resorts, and boutique hotels rate both products similarly between 4.7 and 4.8, with slightly higher review volumes for Oaky.
Given Oaky’s lack of recent review data, Duve’s current 4.6/5 rating from 130 recent reviews provides stronger evidence of up-to-date customer satisfaction.
Edge: Even.
Duve charges a base price of $900 with no freemium option, monthly flat fee, or per-room pricing. There are no implementation fees or trials.
Oaky’s base price is $300 with similar terms—no freemium, no monthly flat or per-room pricing, no implementation fee or trial.
Duve’s higher base price likely reflects its broader feature set and integration complexity, while Oaky’s lower entry point suits hotels seeking a focused upselling tool with less upfront investment.
Hotels that require a multi-channel guest communication platform integrating SMS, WhatsApp, email, and in-app messaging.
Properties that want a comprehensive guest app offering mobile check-in, checkout, local recommendations, and direct payment capture.
Hotel groups or vacation rental managers who value extensive PMS and third-party integrations for seamless data flow.
Teams aiming to reduce front desk workload through automation of check-in, upselling, and guest messaging tasks.
Luxury and boutique hotels needing customizable upsell campaigns tailored by guest profile, loyalty status, and in-house services.
Not ideal if:
You seek a lightweight, single-purpose upselling tool without the complexity of a full guest engagement platform.
Your hotel has limited IT resources to manage a broad integration setup and customization.
You require immediate, out-of-the-box upselling with minimal training and onboarding.
Hotels focused primarily on driving upsell revenue through pre-arrival and front desk offers with automation and segmentation.
Luxury and branded hotels that benefit from dynamic pricing and gamified front desk upselling for staff motivation.
Properties looking for a user-friendly platform with strong customer support and onboarding.
Hotels that want to quickly deploy upselling campaigns integrated with major PMS systems.
Not ideal if:
You require a comprehensive guest engagement platform including guest messaging, mobile check-in, and multi-channel communication.
Your hotel portfolio includes vacation rentals or extended stay properties with less representation in Oaky’s user base.
You need a platform with recent, verified customer feedback to assess current product quality.
Duve Upselling and Oaky by Plusgrade both boost hotel revenue through upselling but serve different operational priorities. Duve’s comprehensive platform integrates upselling into a wider guest engagement and communication ecosystem, supporting multi-channel messaging, digital check-in, and third-party marketplace offers. Oaky concentrates on automated, segmented upselling with dynamic pricing and gamification to optimize ancillary revenue and front desk performance.
Choose Duve if your property requires a versatile, all-in-one guest experience platform with broad PMS integrations, multi-channel communication, and personalized upsell offers. Duve’s 31 unique features and recent positive reviews demonstrate its strong operational impact at luxury hotels, vacation rentals, and large groups.
Choose Oaky if your hotel prioritizes streamlined upselling workflows with advanced automation, guest segmentation, and staff motivation tools. Oaky’s higher customer support ratings and strong segment scores at luxury and branded hotels confirm its effectiveness. However, note Oaky’s sharp drop in review activity in the past six months, which may affect confidence in current performance.
In summary, Duve offers operational depth and integration breadth for hotels seeking a unified guest experience solution that drives revenue across multiple touchpoints. Oaky delivers focused upselling excellence with dynamic pricing and gamification but has limited recent review validation. Your choice depends on whether you value a holistic guest engagement platform or a specialized upselling engine.

The HT Score is a composite ranking that considers 4 criteria groups and over a dozen variables to help hoteliers objectively compare hotel technology products. Duve has an HT Score of 98 and Oaky by Plusgrade has 87. Here is how the score is calculated.
| Criteria Group | Weight | What It Measures |
|---|---|---|
| Customer Ratings & Reviews |
|
How highly do users recommend this product? Ratings Score, Review Volume, Share of Voice, Review Depth, Review Recency, Success Stories ▾ The most heavily weighted factor. Analyzes average satisfaction ratings (likelihood to recommend, ease of use, support, ROI), total review count relative to category peers, review recency (at least 20 reviews in the trailing 6 months), and share of voice across unique hotel clients to detect selection bias. |
| Partner Ecosystem |
|
How highly do tech partners recommend this company? Partner Recommendations, Integration Quantity, Integration Quality ▾ Evaluates partner recommendations as expert votes of confidence, the number of verified integrations, and ecosystem quality — the average HT Scores of integration partners. Products with higher-quality integration ecosystems are more likely to deliver a connected tech stack. |
| Customer Centricity |
|
How customer-centric is this organization? Certified Support, Review Consistency, Profile Completeness ▾ Assesses whether the company has earned HTR Customer Support Certification, maintains consistent review collection over time (an indicator of feedback-driven culture), and keeps product profiles complete with capabilities, screenshots, pricing, and features. |
| Reach, Staying Power & Resources |
|
How extensive is this company's reach and resourcing? Geographic Reach, Staying Power, Company Resources, Trending Score ▾ Measures global presence (countries and regions served), years in business as a stability proxy, team headcount as a resource proxy, and a trending score based on trailing-twelve-month buyer inquiries, reviews, partner recommendations, and press activity. |
Customer ratings and reviews are by far the most important factor in the HT Score algorithm. HTR does not accept payment for higher rankings. All reviews are verified — only hotel industry practitioners with confirmed affiliations can submit ratings. View full HT Score methodology →
