If you're comparing CT Corporation and CSC, you've already concluded that your current compliance infrastructure isn't scaling with your portfolio. Both are legacy enterprise providers built around managed-service models: your team submits requests, their team executes, you receive confirmations and invoices. That can work at low entity counts. Past 50 entities with a lean legal or operations team, I'd expect that coordination overhead to compound with every filing cycle.

This comparison focuses on the workflows PE firms stress most: annual report filing at scale, multi-entity payment segregation, and coverage gaps created by billing disputes or account transitions.

Why platform selection matters more at portfolio scale

CT Corporation and CSC both require a service team to execute filings on your behalf, which works until entity count makes manual coordination the bottleneck. The 2023 ACC LEM report found that 27% of organizations have no process to monitor annual compliance obligations and 30% have no compliance calendar.

For PE firms adding portfolio companies through acquisitions, those gaps compound with every deal: PitchBook's Q3 2025 breakdown puts add-ons at 74.1% of US buyout transactions, with 3,300 add-ons closed year to date, and each add-on generally arrives with its own entities to foreign-qualify and track.

ILPA Principles 3.0 states that the cost of satisfying regulatory requirements at the firm level should be borne by the GP out of the management fee. In practice, that's often not what happens: ILPA's 2020 Fund Terms Survey found that 70% of respondents observed regulatory filing and compliance costs excluded from the management fee and allocated to the partnership over the prior 12 months, a real gap between the stated principle and market practice.

How CT Corporation, CSC, and Discern compare

The table below shows where the platforms diverge, based on what each provider publishes on its own product, pricing, and trust pages as of publication; "not documented publicly" means unpublished, not missing.

The core difference is the automation model. CT Corporation's hCue platform is the system of record for entity data, and its annual report managed service (ARMS) files separately. CSC works the same way; neither removes humans from the filing loop.

Discern files automatically: the platform pre-fills forms, calculates due dates from entity-specific data, and submits without manual initiation. For a lean team past 100 entities, that difference decides how much of the week compliance takes.

Pricing transparency and total cost of ownership

CT Corporation and CSC do not publish pricing; all figures require direct vendor engagement. Discern's pricing is public: $350 per state per year for the base subscription, which includes registered agent service, annual report filing, and Delaware franchise tax automation. Entity formations are $99 plus state fees, foreign registrations are $99 plus state fees, PLLCs and PCs are $249 plus state fees, and change of agent filings are free.

Choosing the right platform for your portfolio structure

The right choice depends on portfolio size, operating model, and the degree of automation you need.

50 to 100 entities, defined domestic structure, cost transparency priority: Discern's model warrants serious evaluation. Reference-check performance claims at 200+ entity scale before committing.

PE firms across portfolio sizes: address per-entity billing segregation explicitly in your evaluation process, for clean allocation, audit trails, and fund and entity payment segregation. A SOC 2 report can only be issued by a licensed CPA firm performing an attestation under AICPA standards, so ask each vendor for the auditor-issued report, its audit period, and its scope, rather than accepting a self-declared alignment statement.

Exit readiness is the highest-stakes consideration

Entity management problems become most expensive when they surface during diligence rather than during routine administration. Good standing lapses discovered during acquisition due diligence can affect contract enforceability and delay closing, which is why diligence counsel routinely requires current good-standing certificates before signing.

Bain & Company's Global Private Equity Report 2026 counts roughly 32,000 unsold portfolio companies worth $3.8 trillion, with average holding periods at exit now drifting toward seven years. The longer a company sits in a portfolio, the more entity-level issues, whether lapsed registrations, unresolved foreign qualifications, or thin audit trails, tend to accumulate and surface at the worst possible moment: during exit diligence, where they can reduce purchase prices, expand indemnification escrows, or extend earn-out provisions.

Reduce entity compliance overhead across your portfolio with Discern

PE firms need one system for registered agent coverage, annual report filings, foreign registrations, and Delaware franchise tax across every portfolio entity, without administrative overhead scaling alongside entity count. Discern bundles those into a single $350 per state per year subscription, with no separate platform fees and no separate service charges for annual report filing.

For firms managing 100+ entities across multiple states, Discern's autofilings run in perpetuity without manual input, and customers with 200+ state registrations complete annual filings in 5 to 10 minutes. Entity payments support separate bank accounts and cards per entity for fund and portfolio company segregation, and Discern audits entities before onboarding to remediate historical compliance issues.

Frequently asked questions

These answers recap the comparison points PE teams raise most often when evaluating the two legacy providers.

How do CT Corporation and CSC actually differ from each other?

Less than you might expect. CT Corporation splits entity data (hCue) from filing execution (ARMS), while CSC's service team files with advance notice; both run managed-service models that keep humans in the filing loop.

What should a PE firm verify before signing with any provider?

Documented per-entity billing segregation, customer references at your actual entity count, and the vendor's auditor-issued SOC 2 report rather than a self-declared alignment claim.

Why does per-entity billing segregation matter for a PE firm?

It puts each filing cost on the portfolio entity that incurred it and leaves a per-entity audit trail instead of one pooled invoice to unpick later. Discern also supports a separate bank account and card per entity, which keeps fund-level spending apart from portfolio company spending.

How long does onboarding to Discern take for a portfolio with 100+ entities?

Discern audits entities before onboarding to identify and remediate historical compliance gaps first, so good standing is established before the switch rather than discovered afterward. Exact timing depends on portfolio complexity and the condition of existing entity data; ask for a reference customer at your entity count.
