K Wish List vs Fish Wishlist & Quote Request: Comparison

Introduction

Choosing the right wishlist app is deceptively important. A lightweight wishlist can increase saves, social shares, and eventual conversions, while a wishlist built for B2B needs can transform browsing into draft orders and quotes. Merchants often choose between focused, single-purpose apps and broader, multi-tool platforms — each approach carries trade-offs that affect retention, average order value, and long-term growth.

Short answer: K Wish List‑Advanced Wishlist is an excellent fit for merchants who want a simple, fast-to-launch wishlist with essential customization and social sharing. Fish Wishlist & Quote Request is better suited for stores that need omnichannel wishlist behavior with B2B features, POS support, and quote/draft-order workflows. For merchants who want to reduce app sprawl and invest in retention across loyalty, reviews, referrals, and wishlists, Growave presents better value for money as an all-in-one platform.

This article provides a feature-by-feature, data-driven comparison of K Wish List‑Advanced Wishlist (Kaktus) and Fish Wishlist & Quote Request (Native App Co). The goal is to help merchants understand strengths, weaknesses, and right-fit use cases, then explore how a consolidated retention stack can reduce complexity and improve lifetime value.

K Wish List‑Advanced Wishlist vs. Fish Wishlist & Quote Request: At a Glance

Deep Comparison

Core Features and Wishlist Behavior

K Wish List‑Advanced Wishlist — What it delivers

K Wish List focuses on the core buyer behavior of saving and sharing. Its main features include:

• Multiple display options: floating button, header/nav icon, popup, and embedded wishlist page.
• Customizable labels, icons, and colors to match store branding.
• Social sharing for wishlists and notifications to encourage sharing for gifts and events.
• Customer wishlist pages so logged-in shoppers can return to saved items.
• Basic tracking of wishlist usage to surface popular products.

These features make K Wish List functionally complete for stores that want shoppers to save items and come back later. The app’s 4.7 rating across 81 reviews signals broad satisfaction among merchants using the app for this type of behavior.

Benefits for merchants:

• Low friction setup and UX for customers who are comparison-shopping or creating gift lists.
• Visible social sharing options that can drive referral traffic during holidays.
• Free plan availability lets merchants test wishlist impact before committing.

Limitations:

• No built-in B2B quoting, draft orders, or advanced POS workflows.
• Feature set is focused on saves/shares; advanced analytics and cross-channel automation are limited.

Fish Wishlist & Quote Request — What it delivers

Fish Wishlist positions itself as a wishlist plus commerce workflows tool. Core features include:

• Fast setup and checkout/account widgets to capture saves across touchpoints.
• B2B support: request-a-quote, draft order creation, and B2B pricing for trade customers.
• Shopify POS integration so wishlists and purchase histories can be accessed in-store.
• Social proof widgets and sharable wishlist links.
• Multi-language and multi-currency support.

Fish’s 5.0 rating (from 7 reviews) suggests very positive experiences from a small sample. The core advantage is combining wishlist saves with business processes like quotes and draft orders, which matter to wholesale and high-touch merchants.

Benefits for merchants:

• Enables sales teams to turn wishlist selections into draft orders and formal quotes.
• Omnichannel support (POS + online) for stores with hybrid retail models.
• Strong fit for merchants that need wishlist functionality to feed complex sales cycles.

Limitations:

• Higher price tiers for advanced features can be significant for small stores.
• Smaller number of reviews means less broad user feedback to reference.
• White-glove installation available, but that can increase time and cost to go-live.

Customization, UX, and Branding

K Wish List emphasizes a lightweight, brandable UX. Options include customizing the look of the floating button, labels, and colors so the wishlist matches site design. For merchants prioritizing visual consistency and minimal design changes, K Wish List does well because it keeps required theme edits small and delivers common wishlist display patterns.

Fish offers more structural customizations tied to workflows — e.g., checkout upsell widgets, account page extensions, and wishlist list links. When stores require wishlist items to feed quote forms or POS screens, Fish’s UX leans toward operational flexibility rather than sole visual polish.

Practical differences:

• If the primary goal is a clean, visually integrated save-for-later experience, K Wish List will achieve that quickly.
• If wishlist entries must be actionable in sales workflows (quotes, draft orders, POS), Fish provides the hooks to make that interaction seamless.

Sharing, Social Proof, and Virality

Both apps provide social sharing for wishlists, but the strategic intent differs.

K Wish List:

• Focuses on social sharing for gift occasions and peer-to-peer discovery.
• Social sharing tends to generate direct referral traffic to product pages.

Fish:

• Adds social proof widgets and sharable wishlist links that can be used in marketing or sales outreach.
• Enables use of wishlist behavior in signaled social proof (e.g., “X customers saved this item”).

For merchants that heavily rely on gifting, seasonal campaigns, or influencer amplification, K Wish List’s straightforward sharing is effective and cost-efficient. For merchants looking to convert wishlist interactions into social proof visible site-wide, or to drive sales teams with social signals, Fish’s social proof features are more flexible.

Integrations and Ecosystem

K Wish List lists Checkout as a working surface and focuses on basic wishlist features. Its simplicity reduces integration complexity but limits advanced automation.

Fish integrates with a broader set of Shopify surfaces and external tools:

• Shopify POS, Customer Accounts, Shopify Flow, Checkout Extensibility, Klaviyo, and Draft Orders are specifically supported.
• The Klaviyo and Flow integrations enable automation paths based on wishlist behavior — for example, triggering targeted emails or flows when a wishlist item becomes low in stock or when a customer abandons a wishlist.

Why integrations matter:

• Merchants that rely on automated lifecycle marketing need wishlist events pushed into email and automation platforms. Fish’s Klaviyo and Flow hooks are valuable for this type of automation.
• Stores that prefer a simple wishlist and minimal automation can avoid complex integration needs and use K Wish List to reduce engineering overhead.

B2B, POS, and Enterprise Considerations

Fish’s differentiator is clear: B2B features and POS support. Specific functionalities include:

• Request a Quote and draft order creation directly from wishlist items.
• Auto-invoicing and quantity pickers for trade pricing workflows.
• POS access so in-store staff can reference wishlists and purchase histories.

K Wish List does not offer these enterprise/B2B workflows. Its architecture is optimized for consumer-focused behavior, not sales operations.

Who benefits most from Fish:

• Wholesale or trade brands that need formal quote workflows.
• Brands that have both online and in-person sales channels and want wishlist continuity across POS and web.
• Stores that want direct draft-order creation from wishlists to streamline B2B sales.

For pure DTC brands without B2B sales cycles, Fish’s advanced feature set may be unnecessary and more costly than the benefits delivered.

Pricing & Value for Money

Both apps offer free plans and paid tiers, but their pricing philosophies differ.

K Wish List pricing summary:

• Free plan with core wishlist functionality (float button, header icon, add-to-wishlist, notifications, social sharing, popups, customer wishlists).
• Growth: $6.70/month with same feature list (may include higher limits or support priority).
• Growth 2: $19.99/month with similar feature pack.

K Wish List’s pricing is accessible and positions the app as a budget-friendly way to add wishlist functionality. For merchants needing basic saves and social sharing, the free plan is a low-risk test.

Fish pricing summary:

• Starter Wishlist: Free (two-minute setup, up to 100 customers, Shopify Flow triggers, Klaviyo integration).
• Lightning: $40/month (unlimited wishlists, migration support, checkout upsell, account extension).
• Trade: $90/month (B2B features: request a quote, draft orders, auto invoicing, quantity picker).

Value assessment:

• K Wish List is better value for money for stores that only require saving and sharing with minimal operational needs.
• Fish is better value for merchants that convert wishlist interactions into revenue via quote workflows, POS, and B2B processes, but at a higher monthly price.
• Consider the total cost of ownership: Fish’s advanced features can replace other tools (B2B invoicing, draft order management), whereas K Wish List may require additional apps for automation or analytics.

Implementation, Setup Time, and Developer Overhead

K Wish List is marketed as "set up in minutes" with no coding required. Its focus on a few display options and lightweight customization reduces the need for development resources. Merchants on tight timelines or operating without developer bandwidth will appreciate the minimal lift.

Fish also advertises fast setup and offers white-glove installation for merchants who prefer hands-on help. However, because Fish supports POS, quotes, and draft orders, integration may require more configuration (for example, permissions for draft order creation, POS app registration, and Flow automation).

Implementation differences to expect:

• K Wish List: minimal theme edits, rapid launch, quick toggles for button styles and position.
• Fish: potentially more steps for business workflows (setting trade pricing, draft order templates), and coordination across POS and web.

Data & Analytics

K Wish List includes basic wishlist usage tracking so merchants can identify popular items. This tracking is useful for merchandising decisions and identifying product interest.

Fish’s integration with Flow and Klaviyo offers richer automation opportunities. When wishlist events are sent into automation platforms, merchants can create revenue-driving flows (reminders, price-drop alerts, or quote follow-ups) and collect more granular analytics tied to customer profiles.

Merchants who need deeper event tracking for lifecycle marketing will find Fish’s integrations more compelling. Stores with lighter analytics needs will find K Wish List’s built-in metrics sufficient.

Support, Community Feedback, and Reliability

Use the public review signals as one input among many:

• K Wish List: 81 reviews with an average rating of 4.7. The larger sample size gives greater confidence in consistent behavior and merchant satisfaction.
• Fish: 7 reviews with an average rating of 5.0. Very high rating but a small sample size, which means less long-term evidence.

Support offerings:

• K Wish List lists “knowledgeable support” and positions itself as easy to manage.
• Fish advertises white-glove installation and seems to offer services for more hands-on onboarding, which can matter for complex B2B implementations.

Operational reliability considerations:

• Larger review counts reduce the variance in expected experience. K Wish List benefits from many merchant voices.
• Fish’s small but high-rated sample suggests strong experiences among early adopters, particularly for merchants who needed the exact features Fish offers.

Migration & Switching Costs

If migrating from a previous wishlist or consolidating lists, both apps advertise migration assistance (Fish explicitly mentions free migration from other apps on some plans). Migration considerations include exporting saved items and ensuring customer IDs or session data map correctly.

• Fish: explicit migration support is helpful when replacing other wishlist apps that feed into B2B or POS workflows.
• K Wish List: simpler wishlist data formats may be easier to import/export for fundamental save lists but may lack structures for draft orders or B2B line items.

Security, Compliance, and Data Ownership

Wishlist apps store product selections tied to customers or sessions. Both apps operate within Shopify’s ecosystem and leverage checkout and account contexts. Merchants should evaluate:

• How wishlist data is stored and whether it is tied to Shopify customer records (preferred).
• Export capabilities for lost data or switching vendors.
• Compliance with data retention policies and local privacy laws.

Fish’s added handling of quotes and draft orders increases the sensitivity of stored data (e.g., company pricing, invoices). Merchants with B2B obligations should verify how invoice and quote data are treated.

Performance & Page Speed Impact

Lightweight apps that minimize client-side scripts and server calls are important for page speed. K Wish List’s single-purpose approach tends to be lighter by design. Fish, with more widgets and hooks, may introduce more JavaScript on product and account pages — a trade-off for increased functionality.

Merchants should:

• Test page speed (Core Web Vitals) after installing either app.
• Prefer asynchronous loading where possible and avoid rendering quota-heavy widgets above-the-fold unless necessary.

Who Should Choose Which App

Use-case based guidance — avoid declaring a single winner; position them by merchant needs.

K Wish List‑Advanced Wishlist is the right fit if:

• The merchant needs a quick, low-cost wishlist to increase product saves and social sharing.
• Gift-focused or seasonal sales dominate, and the priority is visual integration and minimal setup.
• The merchant wants to test wishlist impact without committing to a larger monthly spend.

Fish Wishlist & Quote Request is the right fit if:

• The store runs B2B or wholesale operations and requires request-a-quote, draft orders, and invoice automation.
• The business has omnichannel needs, including Shopify POS integration and multi-currency support.
• The team wants wishlist events to feed automation platforms and sales workflows directly.

The Alternative: Solving App Fatigue with an All-in-One Platform

Single-purpose apps make sense when a store only needs that single capability. However, most growing brands care about a set of retention outcomes: repeat purchases, higher lifetime value, stronger advocacy, and more authentic social proof. Adding separate apps for wishlist, loyalty, reviews, and referrals quickly creates tool sprawl — more to manage, more friction between systems, and a higher total cost.

This phenomenon is often called app fatigue: the operational burden and integration complexity that arises from maintaining many single-function tools. App fatigue can lead to duplicated data, inconsistent customer experiences, and slower execution of cross-channel campaigns.

Growave’s “More Growth, Less Stack” philosophy addresses app fatigue by consolidating loyalty, reviews, referrals, wishlist, and VIP tiers into one integrated platform. Instead of stitching together multiple vendors, merchants can build coherent retention programs that share customer identities and events.

Key advantages of consolidating into a single platform:

• Unified customer profiles that connect wishlist activity to loyalty status and review requests.
• Less engineering time spent on integration and more time executing campaigns that increase repeat purchase rates.
• Simplified billing and vendor management, which improves clarity on monthly recurring costs.

Growave highlights several integrated capabilities that matter for retention:

• Loyalty programs and VIP tiers that reward repeat behavior and increase customer lifetime value. Merchants can build loyalty and rewards that drive repeat purchases with customizable actions and rewards.
• Reviews and user-generated content tools to collect, moderate, and display social proof. Merchants can collect and showcase authentic reviews to build trust and influence conversion.
• A built-in wishlist that works as part of a larger set of retention touchpoints (rewards for wishlist adds, targeted review nudges for saved items).
• Growth-focused integrations that support enterprise requirements, including dedicated support and architecture for solutions for high-growth Plus brands.

Integrating wishlist behavior with loyalty and reviews produces concrete outcomes:

• When wishlist additions earn points or unlock discounts, customers are more likely to return and convert.
• Wishlist saves tied to loyalty tiers enable personalized communications and recovery strategies for high-intent shoppers.
• Centralized analytics show how wishlist activity correlates with lifetime value, making it easier to prioritize merchandising and product launch efforts.

Growave’s platform is positioned for merchants who want to:

• Replace multiple single-purpose apps with a single retention stack that reduces complexity.
• Gain access to cross-product workflows (for example, reward actions triggered by review submission or wishlist adds).
• Scale into enterprise contexts without replacing core retention systems as the business grows.

For merchants evaluating consolidation, compare the combined costs and operational overhead of multiple single-purpose apps against a single platform fee. Growave provides pricing tiers that accommodate early-stage stores through enterprise clients. Merchants can review plans and see how consolidation affects their tech stack on the pricing page or install directly from the app marketplace. Explore how consolidation impacts vendor count and recurring costs by checking the available plans and trial options on the Growave pricing page and the Shopify App Store listing.

Explore consolidated pricing and plan options to model the difference between a single platform and multiple single-purpose subscriptions. For merchants considering migration or wanting a walkthrough, book a personalized demo to see integrated workflows in action.

Repeated, contextual points about Growave’s relevant product modules:

• Loyalty and Rewards: Merchants can create programs that reward wishlist behavior, referrals, and repeat purchases to increase retention. Check features for creating loyalty and rewards that drive repeat purchases.
• Reviews & UGC: Collect, moderate, and publish reviews to improve conversion and SEO. The platform enables merchants to collect and showcase authentic reviews.
• Shopify Plus & Enterprise: For large merchants, Growave offers tailored support and implementation suitable for solutions for high-growth Plus brands.

Why these links matter in practice:

• Showing loyalty and review modules twice in the product narrative helps merchants visualize cross-product workflows, such as points for review submissions or wishlist-triggered flows.
• Demonstrating Shopify Plus readiness twice addresses the concerns of merchants who foresee scaling into enterprise-level complexity.

Growave also integrates with common marketing and support systems, which reduces the friction of building lifecycle campaigns. Consolidation reduces the likelihood of missed events, mismatched customer IDs, or duplicate triggers that can occur when wishlist events are handled by one vendor and loyalty by another.

Note on migration: moving from a wishlist-only solution to a consolidated platform typically involves exporting wishlist data and mapping customers. Growave’s onboarding and migration resources aim to reduce friction. Merchants should plan for a short period of overlap to ensure no wishlist events are lost during transition.

Migration Checklist (Practical Steps Without Jargon)

• Export wishlist data with customer identifiers from the existing app.
• Map wishlist entries to Shopify customer accounts where possible.
• Identify loyalty and rewards rules that will interact with wishlist events (e.g., reward for adding first wishlist item).
• Test key automations in a staging environment or during a low-traffic window.
• Communicate changes to customers if account UI or wishlist access will look different at first.

Cost Comparison Exercise

Merchants often look only at monthly price and miss hidden costs: developer time, additional apps needed to replicate missing features, and customer experience fragmentation. A short exercise:

• Add up the monthly costs of a wishlist app + a reviews tool + a loyalty app + any required POS or quote tool.
• Compare against a single subscription to an integrated suite that includes these capabilities.
• Factor in savings from reduced integration time and streamlined support.

Many stores find that a unified solution delivers better value for money over a 12-month horizon, even if the monthly sticker price is higher, because consolidated tools deliver more cohesive, measurable retention lift.

Implementation Scenarios and Recommendations

Scenario: Small DTC brand focused on gift-buying and social-sharing

• Recommendation: K Wish List‑Advanced Wishlist provides the fastest route to enable saves and social sharing at low cost. Use built-in social sharing around holiday campaigns and A/B test CTA placement.

Scenario: Mid-market brand with B2B customers and in-store pickup

• Recommendation: Fish Wishlist & Quote Request fits high-touch sales cycles where quotes and draft orders matter. Leverage POS integration and B2B pricing.

Scenario: Growing brand prioritizing retention and LTV across channels

• Recommendation: Consider consolidating wishlist, loyalty, and reviews into a single retention platform to reduce app fatigue and unlock cross-product campaigns. Review consolidated plans and evaluate a trial to measure impact.

Real Metrics To Watch (Apply Regardless of the App)

When installing a wishlist app, track the following KPIs to measure success:

• Wishlist-add rate: % of product page visits resulting in a save.
• Save-to-convert lift: % of wishlist adds that later convert to purchases.
• Social share traffic: visitors from wishlist shares and their conversion rates.
• Average order value for customers with wishlist history vs. those without.
• LTV change for customers engaged via wishlist-based campaigns.

Choose the app that can supply the events or data required to calculate these metrics within the merchant’s analytics stack.

Support and Decision Checklist

Before selecting an app, evaluate:

• Does it integrate with core marketing systems (Klaviyo, Flow, etc.)?
• Are B2B workflows (quotes, draft orders, invoicing) required?
• What is the staff burden to implement and maintain the app?
• What are the migration and data export capabilities?
• Does the vendor’s support model (self-service vs. white-glove) match the merchant’s needs?

Conclusion

For merchants choosing between K Wish List‑Advanced Wishlist and Fish Wishlist & Quote Request, the decision comes down to function and scale. K Wish List is better for SMBs and DTC stores that need a quick, low-cost wishlist with strong social sharing and minimal setup. Fish Wishlist & Quote Request is better for merchants that require B2B workflows, POS integration, and the ability to convert wishlist activity into quotes and draft orders.

FAQ

Q: How do the two apps compare on price for small stores?

• A: K Wish List offers a generous free tier and low-cost paid plans ($6.70–$19.99/mo) that provide key wishlist features with minimal overhead. Fish provides a free starter tier but its core commercial plans (from $40/mo to $90/mo) unlock unlimited wishlists, checkout widgets, and B2B capabilities—so Fish’s price point is higher but includes more commerce workflows. Compare total monthly costs including any additional apps that would be required to replicate missing functionality.

Q: Which app is better for B2B and draft order workflows?

• A: Fish Wishlist & Quote Request is purpose-built for B2B workflows; it supports request-a-quote, draft order creation, auto invoicing, and trade-oriented features. K Wish List is geared toward consumer-focused save-and-share behavior and lacks direct quote/draft-order functionality.

Q: Which app has better integration support for automations (e.g., Klaviyo, Shopify Flow)?

• A: Fish lists explicit support for Shopify Flow, Klaviyo, and Draft Orders, enabling richer automation and lifecycle campaigns. K Wish List provides basic wishlist event tracking but fewer automation hooks. If rich automation is needed, Fish has the advantage.

Q: How does an all-in-one platform compare to specialized apps?

• A: An all-in-one platform reduces the number of vendors, centralizes customer data, and enables cross-product workflows (e.g., reward points for wishlist adds, review campaigns tied to loyalty tiers). While specialized apps can be lower cost in isolation, a consolidated platform often delivers better value for money when considering implementation time, integration maintenance, and the ability to run cohesive retention programs. To evaluate trade-offs, compare the combined cost of specialized solutions against consolidated plan pricing and test how cross-product campaigns affect retention metrics. For integrated retention features and consolidated pricing options, merchants can review the available plans and start trials on the pricing page.
