Engagement management

How we work

A clear process from first conversation to ongoing support.

Each engagement follows a defined path, with secure information handling and CPA review built into the work.

Consultation

Start with a focused conversation about the decisions, obligations, and outcomes that matter.

Understand Your Needs

Review the organization, individuals involved, current records, timing, and engagement requirements.

Engagement & Planning

Define scope, responsibilities, deliverables, and a practical work plan before professional work begins.

Secure Information Exchange

Use supported private document folders and organized information requests for engagement materials.

Preparation & Analysis

Complete the agreed tax, accounting, assurance, or advisory procedures using disciplined workflows.

CPA Review

Professional judgment and conclusions remain under CPA control; technology supports rather than replaces review.

Delivery & Ongoing Support

Deliver agreed work, explain important findings, and continue support according to the engagement scope.

Discuss Your Business

Existing clients

Secure Client Portal

Supported engagements use private client document folders for secure document exchange, information requests, engagement communication, deliverables, notifications, and engagement-related information.

Your private client folder

Access is provisioned individually after an engagement begins. The public website does not accept sensitive tax documents or provide access to separate firm systems.

Why choose us

Why Choose S&S CPA INC

Four commitments that define how every engagement at this firm is run — from a first entity election to a multi-state exit.

CPA-Led Expertise

Direct access to experienced professionals. The CPA who reviews your work is the CPA who takes your call.

Strategic Planning

We anticipate challenges before they become problems — and structure decisions years ahead of the filing.

Confidential Advisory

Your financial information receives the highest level of care, in private client folders under professional standards.

Long-Term Partnership

We grow alongside our clients, from first entity election through succession and exit.

Executive advisory approach

A disciplined method, applied to every client relationship.

Boutique attention with the process discipline of a national firm — so nothing depends on anyone remembering to follow up.

Understand the whole picture

Entities, ownership, compensation, investments, and objectives reviewed together — not one return at a time.

Quantify the opportunity

Every recommendation carries an estimated dollar impact, its supporting authority, and its deadline.

Execute with precision

Elections filed, entries booked, and coordination handled with your attorney and wealth advisor.

Review on a cadence

Quarterly check-ins so the plan responds to your year as it actually unfolds.

Leadership

Senior professionals on every engagement.

You work directly with the people who sign your returns — not a rotating team. That is how a firm of our size delivers big-four discipline with owner-level attention.

Direct answers

What people ask before hiring a CPA.

What does S&S CPA INC do?

S&S CPA INC is a licensed CPA firm in Downey, California providing tax preparation, strategic tax planning, bookkeeping and accounting, outsourced CFO services, and IRS representation. Every engagement is led personally by Selim Hanna, CPA, who is licensed in California, Colorado, and Tennessee and serves clients in all 50 states.

How much does a CPA cost in Downey, California?

Most S&S CPA INC engagements are quoted as a flat fee after a free 30-minute consultation, so the price is known before work begins. The fee depends on entity type, transaction volume, and complexity rather than on hourly increments.

When should a business hire a CPA instead of a bookkeeper?

A bookkeeper records transactions; a CPA is licensed to take and defend tax positions. The switch usually makes sense once a business elects S corporation status, operates in more than one state, carries inventory or job costs, holds real estate, or receives a notice from the IRS or a state tax authority.

Can S&S CPA INC represent me in an IRS audit?

Yes. As a licensed CPA firm, S&S CPA INC has full representation rights before the IRS and state tax authorities — audits, appeals, penalty abatement, installment agreements, and offers in compromise — whether or not the firm prepared the original return.

Do I have to be in Southern California to work with S&S CPA INC?

No. Clients across all 50 states work with the firm remotely through a secure client document exchange, video meetings, and electronic signature. In-person meetings at the Downey office on Paramount Boulevard are available by appointment.

How do I get started?

Book a free 30-minute consultation at calendly.com/selim-cpa-sscpaorg/free-cpa-consultation or call 562-375-1211. You will speak with Selim Hanna, CPA, not a sales representative.

Can the S&S CPA Assistant answer tax questions?

The S&S CPA Assistant can provide general informational help about tax, accounting, audit, and business finance concepts. It is an AI assistant, does not replace a CPA, and should not receive sensitive personal or financial information. Questions requiring professional judgment should be reviewed by S&S CPA INC.
