Comparison Table
SamCart
SMBCheckout and funnel platform optimized for selling digital products.
Session-driven upsells and downsells shown after initial checkout, using one conversion flow model.
SamCart’s core workflow connects page publishing to commerce events like checkout completion so downstream steps like order bumps and upsells can be conditionally shown. The funnel builder includes templates for common funnel steps and produces mobile-responsive layouts for checkout and subsequent funnel pages. A/B variant testing applies to page variants so marketers can measure which page version performs better for a specific funnel step.
A tradeoff is that deep custom funnel logic can require working within SamCart’s specific upsell and downsell flow model rather than building fully bespoke branching for every step. SamCart fits teams that want a controlled set of funnel mechanics with fast iteration through page variants and conversion tracking pixels.
- +Checkout flow includes upsells, downsells, and order bumps in one session
- +A/B variant testing supports rapid iteration on specific funnel steps
- +Checkout and thank-you pages share a consistent editor workflow
- +Conversion tracking pixel can be wired at the funnel or page level
- –Fully custom branching across every funnel step needs design around built-in flow rules
- –Some advanced integrations depend on external automation endpoints like webhooks
- –Complex offer catalog logic can be harder than in commerce-first stacks
- –Session-based funnel logic can limit cross-funnel state beyond the configured flow

Best for: Fits when marketers need session-based upsell flows with quick A/B testing on funnel pages.
Builderall
SMBDigital marketing platform with funnel builder, email, and site tools.
Built-in funnel step editing with A and B page variants tied to conversion reporting.
Builderall covers the core funnel workflow with an editor for landing and sales steps, plus tools for running page variants and measuring performance by step. Funnel projects can include common components such as lead capture, thank-you routing, and upsell and down-sell style flows, using a single funnel builder canvas. Marketing operations are handled through in-platform automation and messaging integrations, which reduces the need for separate middleware in straightforward sequences.
A key tradeoff is that advanced integration control depends more on Builderall’s connector and trigger surface than on a fully open API-first approach. Teams also need governance discipline when many funnel variants and automation branches are edited in parallel. Builderall fits situations where marketers want to iterate on funnel steps quickly and keep the automation logic close to the pages that generate the events.
- +Funnel workflow stays in one editor for pages and step routing
- +A and B page variants support conversion-focused iteration
- +Automation and messaging are available inside the same workspace
- +Reporting ties results back to funnel steps and variants
- –Deep integration control can be limited without broader API surface
- –Complex funnels require stricter change management across variants

Less tool sprawl
Build landing, thank-you, and upsell-style steps within one funnel project.
Best for: Fits when marketers need funnel publishing plus event-triggered automation in one tool.
Kartra
SMBAll-in-one funnel, email, and checkout platform for digital businesses.
Built-in membership access gating connects user purchase status to content eligibility.
Kartra’s differentiator is that funnel steps and revenue steps share the same configuration surface, which reduces cross-tool mapping for common flows like lead-to-checkout and post-purchase upsell. The editor supports template-driven page creation and multi-step funnels, while the automation layer can trigger actions based on form submissions, purchases, and membership status. Built-in components for checkout, order bumps, and membership access gate typical conversion paths without requiring separate checkout or auth tooling.
A tradeoff appears in extensibility and governance, because Kartra’s automation tends to stay within its native modules rather than exposing a deep third-party automation API surface for every event. Kartra fits teams that manage most of the funnel inside one system and need tight alignment between opt-in pages, checkout steps, and follow-up sequences.
- +Native checkout and post-purchase offer steps reduce integration glue
- +Membership access gating supports gated content without extra auth stacks
- +Automation can react to lifecycle events across capture, purchase, and access
- +Reporting links funnel step activity to downstream conversion outcomes
- –Automation outside native modules can require workaround routing
- –Large funnels can create configuration sprawl across many interdependent steps
- –Complex multi-system workflows may need additional external automation components
- –Advanced governance for cross-team access and change tracking feels limited

Use the comparison table and detailed reviews above to validate the fit against your own requirements before committing to a tool.
How to Choose the Right funnel building software
SamCart leads the roundup with session-driven upsells and downsells inside its checkout flow, while Builderall and ClickFunnels focus on funnel-step editing with A and B page variants tied to measurable conversion outcomes. Kartra adds membership access gating that connects purchase status to content eligibility, and GoHighLevel ties funnel events to CRM lead routing and outbound messaging. The remaining tools cover page-first experimentation, webhook-driven eventing, or WordPress-centric funnel step workflows.
Funnel building software for publishing, routing, and testing conversion funnels across funnel steps
Builderall and ClickFunnels push funnel iteration further by tying A and B page variants to conversion reporting and step-level routing inside the funnel workflow. Some tools also extend beyond publishing by mapping page and funnel events into external automations through webhooks and API support, which changes how data moves from funnel steps into CRMs and messaging systems.
Evaluation points for funnel publishing, routing, and testing across steps
Funnel building software has to move data across funnel steps so conversion tracking stays consistent from the first opt-in or landing page to checkout and post-purchase offers. The tools in this roundup differ most by how they connect page variants, step routing, and event reporting.
The next set of features also determines whether teams can iterate fast inside the publishing workflow or whether they must add external automation glue. That is the practical difference between page-centric A/B testing and workflow-centric funnel automation.
Session-driven upsells, downsells, and order bumps inside checkout
SamCart shows session-driven upsells and downsells after the initial checkout using one conversion flow model. This design also brings order bumps into the same session so offer testing stays tied to checkout behavior.
Funnel step editing with A and B variants wired to conversion reporting
Builderall combines funnel step editing with A and B page variants that report against conversion outcomes. ClickFunnels also supports page variant A/B testing at the funnel canvas level with step-scoped tracking.
Funnel-level routing that preserves step-scoped tracking across checkout and post-purchase
ClickFunnels routes leads through checkout and post-purchase sequences while keeping step-scoped tracking aligned to funnel steps. Convertri links steps into a single workflow so step dependencies stay consistent during edits.
Membership access gating tied to purchase status for gated content
Kartra includes built-in membership access gating that connects user purchase status to content eligibility without extra auth stacks. This reduces integration glue when funnels must deliver gated content after checkout.
CRM-native routing and outbound messaging triggered from funnel events
GoHighLevel ties funnel publishing to CRM automation so page triggers update contacts and initiate outbound messaging in one workflow builder. This approach shifts most funnel execution control into CRM-first routing rather than external orchestration.
Experiment management inside the publishing workflow for ordered page variants
Unbounce uses a built-in experiment workflow so page variants and testing states stay organized during iterative funnel changes. Leadpages also provides A/B variant testing in the page workflow, but funnel orchestration remains more page-centric than workflow-centric.
Decision framework for selecting funnel building software by workflow control and automation surface
Selection starts with where the funnel logic should live. Some tools center logic inside checkout sessions or funnel canvases, while others center logic inside CRM workflows or external event routing.
The second decision is how teams want data to flow out of the funnel. Tools differ on whether they keep event mapping and automation inside the same admin workflow or require careful webhook and integration configuration.
Choose the workflow model that matches the funnel logic ownership
If the main optimization is offer switching after the initial checkout, SamCart’s session-driven upsells and downsells keep the offer flow tied to one conversion model. If the funnel needs step-to-step routing with a navigable funnel canvas, ClickFunnels manages funnel steps and routes leads through checkout and post-purchase sequences.
Pick the testing scope that matches iteration speed goals
For teams that want A and B page variants tied to conversion reporting inside the same funnel workflow editor, Builderall supports funnel step editing with variant routing and reporting. If controlled experimentation management matters during iterative publishing, Unbounce organizes experiment variants and testing states inside the publishing flow.
Map the automation boundary for CRM sync and messaging
If funnel events must update deals and contacts and also trigger outbound messaging inside one admin workflow, GoHighLevel connects funnel steps to CRM records and workflow automation. If the funnel needs to publish page events into external systems, Groove.cm emphasizes webhook-driven eventing that maps funnel step activity into external workflows.
Decide whether membership gating is a native workflow requirement
If post-checkout content eligibility must follow purchase status without extra authorization layers, Kartra’s membership access gating directly connects purchase status to gated content. If membership is not central, tools that focus more on step routing such as ClickFunnels or Convertri can keep configuration scope narrower.
Set governance expectations for complex funnel change management
For larger funnel setups where configuration sprawl becomes a risk, ClickFunnels can become harder to adjust when advanced customization becomes template-bound. Builderall warns that deep integration control can be limited without broader API surface, and complex funnels can require stricter change management across variants.
Validate integration reach when advanced logic depends on external endpoints
SamCart notes that fully custom branching across every funnel step needs design around built-in flow rules and some advanced integrations depend on external automation endpoints like webhooks. Convertri also flags that automation depth depends heavily on supported integrations versus custom API flows.
Who funnel building software fits best by execution pattern
Different teams optimize different bottlenecks. Some focus on offer optimization inside checkout sessions, while others focus on funnel routing logic, CRM automation, or gated delivery after purchase.
The right fit depends on whether funnel logic should remain inside the funnel builder or propagate into external systems and CRMs through event triggers.
Marketers optimizing upsells and downsells after checkout
SamCart fits teams that need session-driven upsells and downsells shown after initial checkout with A/B testing on funnel pages. This approach keeps offer testing tied to a single conversion flow model.
Teams standardizing on funnel step workflow editing with controlled variants
Builderall fits teams that want funnel publishing and event-triggered automation in one tool with A and B page variants tied to conversion reporting. ClickFunnels fits teams that want funnel canvas step management with step routing and built-in A/B testing at the page variant level.
Operators needing CRM-native funnel routing and outbound messaging
GoHighLevel fits marketers who want funnel triggers to create or update CRM records and initiate outbound messaging inside one workflow builder. This reduces the need for separate orchestration layers for lead routing.
Teams delivering gated content based on purchase eligibility
Kartra fits teams that require membership access gating that connects purchase status to content eligibility without extra auth stacks. This keeps gated delivery aligned to post-purchase steps.
WordPress teams that want step-based funnel workflows in a site-centric stack
CartFlows fits WordPress marketers who need step-based funnel workflows linking checkout, order bump, and post-purchase pages in one sequence. Its WordPress-centric setup limits fit for teams standardizing on non-WordPress stacks.
Common funnel building software pitfalls that break conversion measurement or iteration
Most failures come from mismatch between testing scope and funnel logic scope. A/B testing a page variant without maintaining step-level routing alignment can produce misleading conversion signals.
Other failures come from event mapping that teams under-configure, which causes webhook or CRM automation triggers to fire on the wrong funnel step or with incomplete context.
Treating page-only testing as sufficient when step routing changes the offer path
Leadpages supports A/B variant testing inside the page workflow, but it keeps funnel orchestration more page-centric than workflow-centric. Use workflow-centric routing tools like ClickFunnels when offer paths depend on step-to-step navigation.
Overbuilding custom branching across many funnel steps without respecting built-in flow rules
SamCart warns that fully custom branching across every funnel step needs design around built-in flow rules. Start with built-in offer structures and expand routing only where session-driven upsells and downsells require it.
Assuming native automation exists for all CRM workflows
Groove.cm relies on webhook and API support to wire page events into external automation, so integration depth depends on external systems. Choose GoHighLevel when CRM-native lead routing and messaging are required from funnel events inside one admin workflow.
Ignoring how variant changes increase configuration sprawl in large funnels
Kartra can create configuration sprawl across many interdependent steps in larger funnel builds. Convertri reduces step dependency wiring during edits by keeping step dependencies consistent in a single workflow.
Letting event naming drift across steps so webhooks misfire downstream
CartFlows notes that automation mapping can require careful event naming to avoid misfires across steps. Use consistent step naming conventions across checkout, order bump, and post-purchase steps before connecting webhooks.
How We Selected and Ranked These Tools
We evaluated SamCart, Builderall, Kartra, ClickFunnels, GoHighLevel, Leadpages, Unbounce, Groove.cm, Convertri, and CartFlows by scoring features for funnel step execution and testing, scoring ease for how directly teams can publish and iterate inside the funnel workflow, and scoring value for how much funnel functionality is delivered without pushing logic into separate tools. Features counted for 40% and split testing, checkout offer steps, and membership gating were weighted because they directly affect how conversion funnels change after publishing.
Ease and value each counted for 30% based on how the funnel canvas or workflow editor keeps routing and variant states organized during edits. SamCart led the ranking because session-driven upsells and downsells live inside its checkout flow with A/B variant testing on funnel pages while keeping the offer experience in one conversion flow model.
