Uncompromising Data Security & Compliance
We safeguard your client data with the same diligence you do. From strict access controls to international security certifications, our infrastructure is built to protect your liability and maintain total compliance.
Display official security logos/badges (SOC 2, ISO 27001) prominently in a sticky side card or directly beneath the main hero section instead of burying them in accordions.
- Tax firms legally require client consent before sharing tax return data offshore under Section 7216. Add a dedicated callout box or downloadable “IRC §7216 Compliance & Consent Template Kit for CPA Partners” to eliminate legal friction immediately.
Independently audited controls for data security, availability, and confidentiality.
Adherence to IRS Publication 4557 (Safeguarding Taxpayer Data), GLBA, and CCPA standards.
AES-256 encryption in transit and at rest, zero local data storage on end-user machines, and multi-factor authentication across all environments.
Flexible Engagement Models Built Around Your Firm’s Workload
No two firms operate on the exact same cycle. Choose a primary structure below, or combine models to cover year-round baselines alongside seasonal spikes.
- Dedicated FTE (Full-Time Equivalent): A named, full-time preparer dedicated exclusively to your firm’s files. Best for: Steady, year-round volume and long-term capacity expansion.
- Pay-Per-Return / Per-Transaction: Variable pricing per 1040, 1120-S, or monthly reconciliation. Best for: Managing tax season overflow without adding fixed overhead.
- Block Hours: A pre-purchased pool of flexible hours drawn down as work arrives. Best for: Unpredictable backlogs, client cleanup, and special projects.
- Fixed Monthly Scope: A predictable, recurring flat fee for standard deliverables. Best for: Client Advisory Services (CAS) and ongoing monthly accounting.
Risk-Free Onboarding: Pricing is tailored to return complexity, volume commitments, and turnaround speed. Most partners start with a low-friction paid pilot before selecting their long-term mix.

Frequently Asked Questions
CPA outsourcing services mean assigning accounting, bookkeeping, tax preparation, or reporting work to an external team that operates as an extension of your firm — easing workload pressure so you can focus on advisory and client relationships.
It depends on the model and complexity. Dedicated FTE arrangements bill monthly; per-return pricing suits seasonal work. Straightforward bookkeeping costs less than multi-state returns, and higher volume improves your effective rate.
Yes. Under IRC §7216, a US preparer must obtain written client consent before disclosing return information to a preparer outside the United States. We build that workflow into onboarding.
We work in the platforms US firms rely on — including UltraTax CS, Lacerte, Drake, ProConnect, ProSeries, and CCH Axcess and adapt to your existing setup.
Our offshore delivery is built on SOC 2 and ISO 27001 controls, restricted access, encrypted file sharing, and signed NDAs. Ask any provider for their security documentation before you sign.
There's no hard floor. Most firms begin with a pilot, a batch of returns or one month's close — before committing.
Yes. Delivery runs from our offshore centers with US-hours coverage for review calls and escalations. That's why the economics work. Your firm still signs the return, owns the client relationship, and makes every judgment call.
