Common reasons platforms switch
The trigger is different for every firm. But the underlying pattern is the same — your provider’s roadmap no longer matches yours.
Your provider has changed focus
Providers get acquired, pivot to institutional markets, or shift to different asset classes. What worked when you signed up may no longer be their priority. If you’re not getting feature development, responsive support, or UK-specific expertise, that’s a signal.
You’re paying more as you grow
AUM-based pricing punishes success. If your provider charges a percentage of assets under management, your costs grow every year — even on historic investments that aren’t generating new activity.
You need more than an ISA wrapper
If you’ve bolted an ISA manager onto a platform you built yourself, you’re maintaining two systems. A single platform that handles ISA admin, onboarding, compliance, and a branded portal eliminates integration headaches.
You want your own brand
Your investors should interact with your brand — not your infrastructure provider’s. If your current ISA manager puts their name on communications, they're communicating with your customers, or the portal, you’re building their brand with your investors.
What changes when you switch
A flat monthly fee with transaction-based pricing means your costs reflect what you’re actually doing — not what you did three years ago.
Typical legacy provider
- AUM-based pricing — costs grow every year on historic investments
- Their brand on your investor communications
- ISA wrapper bolted onto a separate portal you maintain
- Feature roadmap driven by institutional clients, not UK platforms
- Limited UK-specific support as provider pivots globally
- Manual reconciliation between your systems and theirs

What you get with ShareIn
Everything you need to run a compliant investor-facing platform — under your brand, with flat-fee pricing.
HMRC-Registered ISA Manager
IFISA administration, subscription tracking, annual HMRC returns, void/repair, transfer-in/out handling.
White-Label Investor Portal
Your brand, your domain. Investors log in to see holdings, valuations, and documents.
Flat Fee Pricing
Monthly software fee plus transaction charges. Costs reflect activity, not the size of your historic book.

CASS Client Money

Loan Management
Interest accrual, tranche structures, waterfall distributions, borrower reporting.
Migration timeline
Typical 8–12 weeks from kickoff to go-live. No disruption to your investors.
Gap analysis
We review your current ISA setup — investor data, subscription history, wrapper types, HMRC reporting status. We identify any gaps and produce a migration plan with a clear timeline. No commitment required to get to this point.
Platform setup
We configure your ShareIn environment — branded portal, ISA wrapper settings, KYC flows, investor communications templates. If you’re adding capabilities (loan management, bond subscriptions, regulatory hosting), these are set up in parallel.
Data migration & ISA transfer
Investor records, ISA subscription histories, and holding data are migrated using our dedicated migration tooling. We handle the bulk ISA manager transfer with HMRC — your investors retain full ISA continuity without needing to withdraw and resubscribe. We reconcile every record.
Testing & investor comms
Parallel running to verify data accuracy. We draft investor communications (under your brand) explaining the transition. Your team reviews the portal, reporting, and ISA functionality before go-live.
Go-live & cutover
Investors are redirected to your new branded portal. Old provider decommissioned. We handle any remaining ISA transfers-in that are in flight. Post-migration support for 30 days to resolve any edge cases.
Purpose-built migration tooling
We’ve built dedicated tooling to migrate investor data, ISA subscriptions, and account histories from other providers. The tool handles data mapping, reconciliation, duplicate detection, and ISA transfer validation — reducing manual work and the risk of errors. It’s been used in production and we know where the edge cases are.
Common questions
No. ISA-to-ISA transfers preserve full continuity. Your investors don’t need to withdraw, resubscribe, or use any of their annual allowance. Their ISA history transfers intact.
Minimal. Depending on your current setup, investors may need to accept updated terms and verify their identity on the new portal. We design the process to require as few steps as possible.
Live investments transfer with the ISA. Interest payments, loan repayments, and maturity events continue as normal — just processed through ShareIn instead of your previous provider.
We charge a flat monthly software fee plus transaction-based fees. You pay for what you do, not what you hold. For platforms with large historic investment books, this is typically significantly cheaper than AUM-based billing.
Yes. Many firms use a migration as the opportunity to add features they didn’t have before — a branded investor portal, loan management, or bond subscription capability. It’s more efficient to do this alongside the migration than as a separate project.
We can provide ISA manager services as a standalone offering. But most firms find that once they’re migrating, adding the investor portal and compliance reporting makes sense — the marginal cost is low and the value is high.
