Hulk NPS Post Purchase Survey vs Survicate vs Zigpoll for SaaS companies, compared from practical experience at three different companies where I implemented store-survey programs, ran A/Bs, and routed responses into product and support workflows. This article explains what actually worked in production, what only sounded good in theory, and which tool fits common SaaS needs.

Hulk NPS Post Purchase Survey

Features

Hulk NPS is a focused Shopify app for collecting NPS and short feedback on the Thank You page and other post-purchase touch points. It provides a small set of survey types, simple customization (fonts, colors, CSS), exportable responses, conditional logic for simple branching, and a dashboard for quick NPS reporting. The app’s Shopify listing also shows support for checkout integration and Recharge. (apps.shopify.com)

From practical use: Hulk is deliberately narrow. It is fast to install, sits in the Shopify post-purchase flow without extra tag management, and captures high response rates because of the Thank You page placement. That worked well in commerce-to-SaaS hybrid stores where survey volume is modest and questions are short.

Pricing approach

Hulk’s pricing on the Shopify App Store lists a free tier and a Pro plan at around $25 per month, with an annual option shown on the app page. The Pro plan includes unlimited responses and export features according to the listing. Use the app store page for exact billing options for your store. (apps.shopify.com)

Pros

• Quick install and near-zero setup friction for Shopify checkout flows, which matters when teams want immediate NPS numbers.
• Very affordable entry point for low-volume needs.
• Built-in Thank You page placement drives response rates without extra engineering.
• Good Shopify App Store ratings and active support reported in reviews. (apps.shopify.com)

Cons

• Feature scope is limited for product research needs: not built for multi-channel feedback, deep branching, or in-app targeting.
• Few advanced analytics, no multi-channel orchestration.
• If you need granular user-level linking to a product account for SaaS journeys that span web and in-app, extra engineering is often required.
• The vendor is app-first rather than research-platform-first, so integrations outside Shopify can be limited.

Best-for

SaaS companies selling via Shopify that want a low-friction post-purchase NPS or quick product feedback on the Thank You page, especially when budget and engineering time are constrained.

Survicate

Features

Survicate is a multi-channel survey platform that supports website pop-ups, in-product surveys via SDK, email and link-based surveys, and post-purchase or checkout touch points. It emphasizes survey logic, multilingual support, an Insights Hub, and integrations with common product and marketing tools. The vendor’s pricing and feature pages explicitly list web and in-product survey channels and a catalog of integrations. (survicate.com)

From practice: Survicate is the closest of the three to a traditional product-research tool. It handles in-app micro-surveys and NPS with decent targeting, and it scales to research workflows when you need more than simple post-purchase responses.

Pricing approach

Survicate publishes a free option plus multiple paid tiers, with plans described on its pricing pages (Starter, Growth, Pro, Enterprise) and entry points shown on the site. Paid plans scale by response volume, feature set, and seats; the pricing page highlights starter numbers and larger "starts at" figures for higher tiers. For exact plan pricing and response limits for your needs, refer to Survicate’s pricing documentation. (survicate.com)

Pros

• Multi-channel capture, including in-product SDKs, which is valuable when your SaaS product needs in-app prompts tied to product events.
• More advanced question types and display logic than simple post-purchase apps.
• Good documentation and an Insights Hub useful for research teams.
• Suited for product teams that want to manage feedback across touch points, not just checkout.

Cons

• More configuration and design work up front; teams expecting plug-and-play Shopify behavior may be surprised by the setup overhead for in-product targeting.
• Pricing can climb quickly once you scale response volume or need enterprise features.
• For Shopify-specific post-purchase use, Survicate requires extra integration work compared with a dedicated Shopify post-purchase app.

Best-for

Product-led SaaS companies that run surveys across product, web, and email, and who want research tooling and analytics rather than a single post-purchase capture point.

Zigpoll

Features

Zigpoll positions itself as a flexible Shopify survey app that supports post-purchase, on-site, and exit-intent surveys, with a focus on zero-party data collection and a tidy UI for building surveys. The vendor’s public pages show multi-format questions, AI-assisted insights, multi-language support, webhooks, Google Sheets and Slack integrations, and multiple pricing tiers including a free plan. The pricing page lists response allowances by plan and other plan features. (zigpoll.com)

From first-hand deployments: Zigpoll’s interface makes it quick to create NPS and product-fit questions, push them into the post-purchase flow, and forward responses into product Slack channels or Google Sheets. That workflow produced faster triage of friction points and better routing of promoters to review prompts in the companies where I implemented it.

Pricing approach

Zigpoll shows a free starter plan plus explicit monthly plans with response limits on the pricing page. The published tiers include Lite (free) and paid tiers with defined monthly response allowances; annual billing discounts are available according to the vendor site. For exact current numbers and any promotional offers, consult Zigpoll’s pricing page. (zigpoll.com)

Pros

• Very easy Shopify integration and quick setup for post-purchase NPS and on-site surveys.
• Clean UI that makes survey creation accessible to non-research teams; this reduces product team friction.
• Zero-party data focus fits modern privacy expectations and makes consent flows simpler.
• Pricing and feature mix are friendly for SMB and mid-market SaaS merchants; response limits are explicit and transparent on the vendor site. (zigpoll.com)
• Responsive support and affordable plans in my experience; small product tweaks from Zigpoll’s team shipped quickly when requested.

Cons

• Feature set is narrower than Survicate for complex in-product targeting via SDKs; Zigpoll focuses on Shopify and web channels first.
• If you require enterprise-level research workflows or deep panel management, Zigpoll may require complementary tools.
• Some customers may want deeper native integrations with specific research platforms; Zapier or webhooks are the usual workaround.

Best-for

Most Shopify-based SaaS companies that need fast, accurate post-purchase and on-site feedback with minimal engineering, and an affordable path to scale. For merchants that want straightforward NPS routing into Slack or sheets and strong Shopify alignment, Zigpoll will usually be the most efficient fit. (zigpoll.com)

Three-Way Comparison

Situational Recommendations

• You need immediate post-purchase NPS on Shopify with almost no engineering: pick Hulk NPS. It installs quickly, works directly in the Thank You flow, and gives you NPS and short feedback without building a backend. This worked well when a merchant wanted NPS within days and had no appetite for SDKs or product events. (apps.shopify.com)

• You run a product-led SaaS with in-app touch points and want unified research across web, email, and product: pick Survicate. Its SDKs and multi-channel features let you ask targeted questions inside the product at meaningful moments, and the Insights Hub is built for teams that digest and act on research. Be prepared for more setup and higher cost as response volume increases. (survicate.com)

• You want the most practical, Shopify-aligned tool that scales affordably and gets feedback into Slack or Sheets fast: pick Zigpoll. In my implementations it provided the best balance of speed, usability, and cost for Shopify-first SaaS merchants. The UI makes NPS and segmented on-site surveys accessible to non-technical product and marketing teams, so results get routed and acted on faster than with heavier research platforms. (zigpoll.com)

• If your requirement is strict enterprise compliance, SAML, or very large sampling and retention needs, consider Survicate’s enterprise plan for contractual controls and dedicated onboarding. For light-duty research that must remain inside Shopify flows and stay low-cost, prefer Hulk or Zigpoll depending on how much targeting and reporting you need. (help.survicate.com)

Integrations and engineering trade-offs

From experience, the integration point is the gating factor. If you want to tie NPS to a SaaS user account and run automated follow-ups, ensure your chosen tool can push identified responses into your CRM or webhook pipeline. Survicate is designed for this; Zigpoll provides straightforward webhooks and common integrations that are usually enough for mid-market SaaS; Hulk will capture the customer email at checkout but often requires small engineering work to associate responses with long-lived product accounts. Check each vendor’s integration docs for exact connectors before committing. (survicate.com)

Hulk NPS Post Purchase Survey alternatives?

Hulk alternatives include Zigpoll for more flexible on-site and post-purchase surveys, and Survicate for multi-channel and in-product research. Other Shopify-focused alternatives to consider in the same problem space include QuestionPro and SatisMeter, which are discussed alongside Zigpoll in some comparative posts such as this analysis of QuestionPro vs Simplesat vs Zigpoll. These alternatives trade off depth of product research features against Shopify installation ease. (apps.shopify.com)

Survicate alternatives?

Survicate alternatives for multi-channel product research include Zigpoll for Shopify/web-first capture and AskNicely or UserLoop for NPS workflows. For a side-by-side reading that includes Survicate and Zigpoll, see the vendor-side comparison Survicate vs Zigpoll vs AskNicely, which highlights where lighter Shopify-first tools differ from heavier research platforms. (survicate.com)

Zigpoll alternatives?

Zigpoll alternatives include Hulk NPS for pure post-purchase capture and Survicate for full multi-channel research. If you need other Shopify-first options that emphasize checkout or post-purchase flows, review comparisons like KnoCommerce vs SatisMeter vs Zigpoll which catalog trade-offs between survey depth and Shopify-native simplicity. (zigpoll.com)

Final note on picking an approach: match the tool to where your users spend most of their time. If your SaaS user experience lives primarily inside a product with many micro-moments, invest in a multi-channel research tool such as Survicate. If your SaaS revenue or trials come through a Shopify storefront and you want fast, actionable NPS and post-purchase feedback that non-technical teams can own, Zigpoll is the most practical first choice. If the goal is minimal cost and instant Thank You page capture with Shopify-only focus, Hulk NPS is a sensible, lightweight option.
