Store-to-web subscriber migration is a specific operational discipline — not a feature of any existing tool. The alternatives buyers usually weigh against a dedicated migration platform fall into four categories. This page covers each honestly: what it costs, where it breaks, and when it’s the right path instead.

Compared to building it yourself

The honest path: identify the work, scope the engineering investment, and decide whether it fits your roadmap. What “build it yourself” actually requires:
  • Cohort labelling — selecting which subscribers receive migration offers and when, against tenure / plan / geo / engagement criteria
  • Identity bridge — matching subscribers between app accounts and web checkout without breaking entitlement
  • Migration email flow — wave-conditional sends from your domain, with the messaging variants needed for different cohorts
  • Branded checkout on your subdomain — Stripe Checkout configured for subscription billing with the correct trial / pricing / coupon logic per cohort
  • Entitlement sync — writing web subscription state back to your entitlement system (RevenueCat, Adapty, or custom) without breaking the app’s runtime check
  • Wave-level gating — measurement infrastructure to compare migrated vs. matched store-billing holdout, with the discipline to pause if outcomes degrade
  • Subscriber-facing CX — help center articles, ticket capture, macros for the common migration questions
  • Operational rhythm — sequencing waves, handling exceptions, managing cohort-level retries
That’s a 3-6 month engineering project for a competent team, plus ongoing operational load. The math: at 1MARRwith221M ARR with 22% blended app-store fees, every month of delay costs ~18K in store fees that Recurr would have eliminated. When build-it-yourself is the right path: in-house engineering is genuinely available, the project is treated as a strategic priority (not a side initiative), and you’re comfortable with the operational ownership going forward. When it’s not: the project keeps slipping because it’s not the team’s top priority, or the operational complexity exceeds what you’d want to maintain in-house.

Compared to in-app paywall tooling

In-app paywall tools (the category that includes the major vendors here) optimise the in-app subscription experience — paywall variants, free-trial flows, A/B testing of in-app conversion. They sit between your app and Apple/Google in-app billing. What they do well:
  • A/B test paywall designs in-app
  • Funnel tracking through the in-app subscription flow
  • Trial-conversion optimization
  • Cross-platform paywall consistency
What they don’t address:
  • Moving existing subscribers OFF in-app billing onto direct web billing
  • The cohort orchestration, identity bridge, and operational rhythm of migration
  • Entitlement sync between web subscriptions and the app
In-app paywall tooling and Recurr are complementary, not competitive. The paywall vendor optimises in-app conversion at the top of the funnel; Recurr migrates the existing subscriber base off in-app rails afterward. Many migration customers continue using their paywall tooling for new-sub acquisition while running migration through Recurr for existing subs. When in-app paywall tooling alone is enough: the business is acquiring net-new subscribers and there’s no existing book worth migrating off store fees. Pre-migration apps under $1M ARR usually fit this profile.

Compared to a general subscription billing platform

General subscription platforms (the category that handles SaaS subscription billing — recurring invoicing, dunning, plan management) provide the rails for web subscriptions but don’t include the migration mechanic itself. What they do well:
  • Recurring subscription billing on web
  • Customer billing portal
  • Dunning / payment recovery
  • Revenue recognition reporting
What they don’t address:
  • Cohort labelling against tenure / plan / engagement / geo
  • Wave-by-wave migration with matched holdouts
  • Subscriber-facing migration email flow
  • Identity bridge between app accounts and web checkout
  • Entitlement sync to the app’s RevenueCat / Adapty / custom backend
  • Migration-specific CX (help center articles, ticket macros, exception handling)
General subscription platforms can be the underlying rail for web subscriptions post-migration — Stripe Connect, for example, is exactly that. Recurr runs on Stripe, not against it. The web subscriptions Recurr migrates settle to your Stripe Connect account directly. When a general subscription platform alone is enough: you’re starting from zero, building new web subscriptions from scratch, and there’s no existing app-store base to migrate. The migration mechanic isn’t needed because there’s nothing to migrate.

Compared to a generic vendor stack

The “cobble it together” path: pick a paywall vendor, an entitlement vendor, an email vendor, a billing portal vendor, a CDP, a help-center vendor, and integrate them yourself. What this looks like:
  • 6-8 vendor relationships to manage
  • N integration touchpoints between vendors
  • Data continuity between motions (e.g., exit-survey data from Cancel deflections feeding Winbacks) requires custom integration work
  • Each vendor optimises for their slice; nobody owns the migration outcome
When the vendor-stack path is the right call: you have a strong internal RevOps or growth-engineering function that can run multi-vendor integration projects with discipline. Otherwise the integration tax exceeds the migration savings.

When NOT Recurr

The honest cases where another path is right:
  • **Sub-1MARRappsApplesSmallBusinessProgramratesat151M ARR apps** — Apple's Small Business Program rates at 15% all in-app billing; the migration ROI is weaker. Recurr's wedge target is 1M+ ARR where the 30% / 15% blended fee makes migration economically obvious.
  • Apps with heavy organic store-install dependency — apps that rely on Apple’s App of the Day, search rank, or ad-credit relationship have residual store-policy exposure that doesn’t apply to paid-acquisition-heavy apps. Recurr’s ICP skews paid-acquisition.
  • Apps with no reachable subscriber base — anonymous-auth apps without email or another owned channel can’t run migration outreach. Reachability is the first ICP filter.
  • Pre-product apps — Recurr is for apps with an existing app-store subscriber base. If you haven’t shipped the app yet, you’re acquiring new subscribers; migration isn’t the right framing.

What Recurr does that other paths don’t

Three things define a dedicated migration platform:
  1. Cohort orchestration as a discipline — wave-by-wave with matched store-billing holdouts, gates on retention, the operational rhythm to pause and adjust per wave
  2. First-party data continuity across motions — exit-survey data captured at Cancel deflection feeds Winback personalisation; same platform, no integration tax between motions
  3. Founder-led delivery during the early phase — Design Partner Program perks tied to scarcity; the engagement isn’t “configure the dashboard yourself”
The economic case: at the Recurr ICP (subscription mobile apps, $1M+ ARR, reachable base), every month of delay costs more in unrecovered store fees than a migration project costs end-to-end. Run the audit → How it works → Pricing →
