Big1.
One person's accounting firm.

Big1 is the operating system for running a complete CPA-grade accounting firm — registering businesses, keeping books, filing taxes, integrating or replacing every piece of legacy software — with minimal manpower. AI does the work. You provide the vision and the signature where the law requires one.

AI does the work. People provide vision, hands, and oversight. Big1 is the canonical example: one CPA can run what previously needed a 40-person back office, because the platform does the filing, the bookkeeping, the reconciliation, the reporting, the audit trail. The CPA provides the judgment, the regulator-facing signature, the client conversations.

What Big1 actually does

Form

Register a business in any state

Direct integration with Secretary-of-State portals across CA, NY, OH, PA, NV, DE, NC, TN (and growing). Registered-agent service in Delaware. Filings tracked end-to-end with audit-trail attached to every state action.

Run

Run the books natively

General ledger, A/R, A/P, payroll, tax provisioning, month-end close — all native to the platform. Every transaction is a contract-gated entry with quality-gate evaluation before posting. Methodology disclosure on every number.

Integrate

Connect to existing software

Already on QuickBooks, Xero, NetSuite, Sage, FreshBooks? Big1 ingests, mirrors, and either keeps running them under our orchestration or replaces them when you're ready. Run, deprecate, or both — your call.

The capability stack

State filing — 9+ states direct, growing

Big1 doesn't outsource filings to a registered-agent vendor. We integrate directly with each state's SoS portal so filings are first-party, traceable, and reactive to status changes.

Property and tax records research

Big1 runs property-records lookups across county assessors and tax authorities — needed for any real-estate accounting, sale-leaseback, or property-as-collateral transaction. Current direct coverage:

Court records research

Cott RecordHub and Texas Courts research integration. Used for due diligence, litigation lookup, lien search, and bankruptcy/credit checks during onboarding.

Connect to legacy accounting software

Big1's integration layer talks to:

The decision tree: keep running the legacy stack with Big1 as the orchestration layer · deprecate the legacy stack and run natively · both — phase out over a defined transition window. Your call.

Why this works with minimal manpower

The historical CPA firm scaled headcount linearly with client count. Big1's economics are flat — adding clients adds AI work, not human work. One credentialed CPA can run hundreds of clients because the AI handles the filings, the books, the reconciliations, the reports. The CPA's time goes to judgment, regulator interaction, and the rare cases that require human review.

What humans provide:

Vision

Strategic thesis

Which client to onboard. Which jurisdiction matters. When to escalate. What the firm stands for. The operator's judgment over time.

Hands

Signature surface

CPA license attestations. Regulator-facing signatures. In-person verification when required. Board governance.

Oversight

Audit and course-correction

Reviewing the methodology. Catching the AI when it's wrong. Adjusting the playbook. The audit that nothing else can do.

The economics in one line: Big1 turns the traditional 40-person accounting firm into a 1-2 person operation that serves the same or more clients with better methodology disclosure, complete audit trail, and continuous-improvement loops built in.

How an engagement starts

  1. Open the assistant (bottom-right) — describe your firm size, current software, jurisdictions, client mix.
  2. The agent scopes a transition path: register-fresh, migrate-from-existing, or hybrid.
  3. Rob reviews the engagement scope. Anything binding routes for direct review.
  4. Onboarding follows the engagement contract — typically 30 days from signature to first month-end close on the platform.
