What Are Outsourced Accounting Services?

Outsourced accounting services are the use of an external accounting team to manage defined finance and accounting responsibilities on an ongoing basis. Instead of hiring separate employees for every function, businesses can access dedicated professionals who follow established processes, systems, reporting requirements, and review procedures. The scope can range from transactional work to higher-level accounting support.

Outsourced Accounting Services We Provide

Aone Outsourcing provides flexible outsourced accounting services for U.S. businesses and CPA firms. Services can be engaged individually or combined into a broader accounting workflow based on transaction volume, accounting systems, reporting requirements and the level of internal review and approval retained by your team.

Bookkeeping Services

Keep financial records accurate and current with ongoing bookkeeping and reconciliation support. The service can be aligned with your existing chart of accounts, accounting procedures and reporting requirements, helping maintain organized records and identify discrepancies or unresolved items for review without changing your established accounting workflow.

Accounts Payable Services

Support recurring accounts payable activities through an organized workflow for invoices, vendor records, coding, documentation and payment preparation. Aone Outsourcing works within your established approval procedures, while your designated team retains responsibility for reviewing invoices, authorizing payments and releasing funds.

Accounts Receivable Services

Maintain organized receivable records with support for invoicing, payment application, customer account updates and account reconciliation. The workflow can be aligned with your existing accounting system and collection procedures, giving your internal team or CPA firm clearer records for customer follow-up and financial review.

Payroll Services

Add accounting support around your existing payroll process without replacing your payroll provider or changing established procedures. Support can cover payroll-related accounting entries, reconciliations and reporting, while payroll processing, employee decisions and required approvals remain with your designated provider or internal team.

Tax Return Services

Add accounting capacity to applicable U.S. tax preparation workflows through organized financial information and preparation-related support. Work is performed within the agreed engagement scope, while the designated tax professional or authorized party retains responsibility for tax positions, professional judgment, final review and filing decisions.

Sales-Tax Reconciliation Services

Support sales-tax reconciliation by organizing relevant accounting records and reconciliation information within your established systems and procedures. The service can help identify differences and maintain supporting records for review, while responsibility for tax positions, compliance decisions and required filings remains with the designated client or tax professional.

Who We Support

Aone Outsourcing provides outsourced accounting services for two core audiences: U.S. businesses that need additional accounting capacity and CPA firms that need dependable back-office delivery for their clients. Each engagement is structured around the audience's workflow, reporting requirements, systems and internal review responsibilities.

01

U.S. Businesses

Reduce the recurring accounting workload handled by owners, finance managers and internal accounting teams. We support agreed bookkeeping, AP, AR, reconciliations, close and reporting activities, including financial statements and management reports, according to your reporting schedule. Your team retains approval authority and financial decision-making.

02

Growing & Multi-Entity Businesses

Add accounting capacity as transaction volumes, entities or reporting requirements increase. We can support separate books, recurring reconciliations, month-end close and financial reporting across the agreed entities and workflows. Your designated team maintains oversight, reviews completed work and approves financial information before it is finalized.

03

CPA & Accounting Firms

We work as a back-office accounting extension of your CPA firm, using your approved software, workflows, documentation standards and deadlines. We complete the agreed accounting work for your team to review, while your firm retains the client relationship, professional judgment, review responsibility and professional sign-off.

Signs It’s Time to Outsource Your Accounting Needs

As transaction volumes, reporting requirements and business complexity increase, an accounting process that once worked may become difficult to maintain. These signs can indicate that your business or CPA firm needs additional accounting capacity, stronger processes or a more flexible delivery model.

01

Accounting Work Is Taking Too Much Internal Time

When owners, finance managers or CPA professionals spend significant time on recurring bookkeeping, reconciliations, AP, AR and reporting, less time remains for financial management and client-facing responsibilities. Additional accounting support can help separate routine production work from higher-value responsibilities.

02

Month-End Close Is Becoming Difficult to Manage

Growing transaction volumes, unresolved reconciliations and inconsistent documentation can make month-end close increasingly time-consuming. A defined accounting workflow can provide additional capacity for recurring close activities, reconciliations and reporting while keeping review and approval with your designated team.

03

You Are Hiring for Every New Accounting Requirement

Adding employees whenever accounting workloads increase can make team expansion slower and less flexible. An external accounting team can provide support for defined functions or broader workflows, allowing businesses and CPA firms to adjust accounting capacity according to their current requirements.

04

Accounting Errors or Unresolved Items Are Increasing

A growing number of unreconciled accounts, missing documentation or recurring corrections may indicate that existing accounting processes need additional capacity or structure. Dedicated accounting support can help maintain recurring procedures and identify exceptions for review before reporting is finalized.

05

Your Business Has Outgrown Basic Bookkeeping

As a business grows, its requirements may extend beyond transaction recording into month-end close, financial reporting, controller support, budgeting and forecasting. A broader accounting model can provide additional capabilities without requiring every function to be built internally.

06

Your CPA Firm Needs More Delivery Capacity

CPA firms may face increasing client workloads without wanting to expand their internal production team for every recurring accounting task. Offshore accounting support can extend delivery capacity while the firm retains client relationships, professional judgment, review responsibility and final sign-off.

Outsourced Accounting Support for CPA Firms

Aone Outsourcing is designed to fit into the accounting delivery model your CPA firm already uses. We work within your firm's supported accounting software, established procedures, client-specific deadlines and review processes, completing agreed back-office work so your professionals can focus on client service, review and higher-value responsibilities.

01

Work Within Your Firm's Systems & Workflows

Our accounting team works within the software, chart of accounts, documentation requirements and workflow procedures established for each engagement. This allows your firm to maintain its existing accounting environment while we complete the recurring work assigned to the offshore team.

02

Meet Client Deadlines & Review Procedures

Accounting activities are performed according to the deadlines, close calendars and reporting schedules established by your firm. Completed work follows the agreed review process, allowing your CPA professionals to examine accounting records, reports and supporting documentation before information is delivered or finalized.

03

Retain Client Relationships & Professional Sign-Off

Your CPA firm remains the primary client-facing professional. We provide the agreed back-office accounting support, while your firm retains the client relationship, professional judgment, review responsibility and professional sign-off required for the engagement.

04

Extend Your Firm's Accounting Capacity

Add dedicated offshore accounting capacity without requiring your firm to hire for every recurring accounting function internally. We can support defined workloads across your client portfolio, helping your team manage accounting production while maintaining the firm's existing client service, review and approval structure.

How Our Outsourced Accounting Process Works

Aone Outsourcing follows a five-step process that defines responsibilities, completes the agreed accounting work and keeps review and approval with your designated team.

Step 01

Scope

We define the accounting functions, systems, reporting requirements, deadlines and responsibilities included in the engagement. Your designated owner, finance lead or CPA firm representative confirms the scope and identifies who will review and approve completed work.

Step 02

Onboard

We establish the required workflows, documentation requirements, system access and reporting schedule. We introduce our assigned team to the agreed procedures, while your designated team provides the information, access, and instructions required for the transition.

Step 03

Complete the Work

The assigned team performs the agreed accounting activities within your established systems and workflows. Work is completed according to the defined procedures, deadlines and documentation requirements, with issues identified during processing recorded for follow-up.

Step 04

Review & Resolve Exceptions

Completed work and identified exceptions are reviewed according to the engagement's established review process. We address assigned corrections and unresolved items, while your designated finance team, owner or CPA professional provides the required accounting review, judgment and approval.

Step 05

Deliver Reports

Financial statements, schedules and other agreed reports are delivered according to the established reporting calendar. Your designated management team or CPA firm reviewer receives the completed information for final review, financial decisions and approval where required.

Why Choose Aone Outsourcing for Outsourced Accounting

We provide offshore accounting support and financial outsourcing solutions for U.S. businesses and CPA firms that need additional accounting capacity without building every function internally. Dedicated accounting professionals work within your existing systems, workflows and review procedures, while your team retains control over client relationships, professional judgment and final approvals.

01

Dedicated Accounting Capacity

We provide dedicated accounting professionals to support ongoing workloads across bookkeeping, AP, AR, reconciliations, month-end close, reporting and other agreed accounting functions. The team works as an extension of your finance function rather than handling only isolated accounting tasks.

02

Offshore Accounting Delivery

Our offshore delivery model gives businesses and CPA firms access to dedicated accounting capacity without requiring every accounting role to be established within the local team. Work is performed according to the agreed scope, procedures, documentation requirements and reporting schedules.

03

Works Within Your Existing Systems

We work within supported accounting platforms and your established accounting workflows wherever practical. The team follows your chart of accounts, documentation requirements, approval procedures and reporting processes rather than requiring unnecessary changes to your existing finance environment.

04

Scalable Support

Accounting support can be adjusted as transaction volumes, entities, client workloads or service requirements change. You can begin with specific functions such as bookkeeping, AP or reconciliations and expand the scope to include close, reporting, controller or CFO support as requirements evolve.

05

Client Retains Control

We provide the agreed accounting support while your business or CPA firm retains control over client relationships, professional judgment, review responsibility, approval authority and final sign-off. Work is prepared within the established engagement structure for review and approval by your designated team.

06

Structured Review & Quality Control

Accounting activities follow defined procedures and review checkpoints based on the agreed workflow. Human review helps identify discrepancies, incomplete documentation and unresolved items before work is passed to the designated client or CPA firm reviewer.

07

Technology-Enabled Accounting Workflows

We use supported accounting, financial and document platforms to perform assigned work within the client's existing technology environment. This allows accounting activities to remain connected to established systems, records and reporting processes where the required access and workflow can be supported.

How Aone Outsourcing Protects Your Financial Data

Aone Outsourcing handles financial records and accounting information according to the access, documentation and information-handling requirements established for each engagement. Security controls can vary by client system, so we apply only the access and security measures that the relevant platform and engagement support.

01

Controlled Access

Access to client systems and financial information is limited to the responsibilities assigned to the team for the engagement. Access requirements are established with the client and can be reviewed when responsibilities or team assignments change.

02

Client-Approved Permissions

System access and permissions are established according to the client's requirements and the capabilities of the relevant platform. We does not assume that a particular permission structure or access method is available across every accounting system.

03

Secure Information Handling

Financial records and supporting documents are handled through the systems or transfer methods agreed for the engagement. The applicable workflow determines how information is exchanged, stored and accessed during service delivery.

04

Access Changes & Removal

When responsibilities change or an engagement ends, access requirements are reviewed and applicable access is removed according to the client's procedures and the capabilities of the relevant systems.

05

Client Review & Approval Controls

We perform the agreed accounting work, while the client or CPA firm retains responsibility for required professional review, financial decisions, and final approval. Approval authority is not transferred to us unless specifically defined within the engagement.
