Growing your Certified Public Accounting (CPA) practice involves much more than simply adding new customers. You will need sufficient resources (i.e., staff) to complete account reconciliations, end-of-year accounting processes, create documentation supporting your clients’ financial statements, and meet the demands associated with preparing taxes.
When you select the appropriate outsourced bookkeeping and accounting service provider, it will enable your organization to increase its ability to provide service to clients; at the same time, it allows the partners of the firm to focus on their relationship with clients and advising them. Nevertheless, different types of outsourced bookkeeping and accounting service providers have different ways of allocating personnel to tasks, reviewing completed work, and integrating with the systems currently being used by the firm.
This guide will compare OBG Outsourcing against 5 additional providers; comparing their white label support, ability to provide tax prep services, compatibility with your existing work flows, and the different delivery methods each provider offers.

What makes the model different?
An engagement can be organized in the form of a CAS pod. A CAS pod consists of an assigned accountant, a reviewer, a documented monthly-close procedure, backup capabilities, and agreed upon response times.
A business has a logical model for delivering services repeatedly. The model includes who will create the deliverables, who will review them, what documentation is needed with each delivery and how problems can be escalated.
CPA Firms are looking for white-label bookkeeping, recurring CAS capability, and cleanup support within their current work process.
Before you start, agree on who the clients will be, how many transactions they have, which software they can access, what your work product should look like, who is responsible for reviewing your work, and how much of their tax return you will prepare.
2. QX Accounting Services - Board Frim Support and Tax Capacity
QX Accounting Services offers bookkeeping services, year-end accounts, payroll processing services, tax preparation services and support with audits for accounting businesses. QX's offerings include different types of employee arrangements (such as flexible) and different ways to manage your engagements (i.e., Managed Engagement Models).
In addition to describing a two-step review process for its tax preparation services, the tax preparation firm's description of the review process provides an opportunity to discuss how other tax preparation firms may use different types of review processes when considering whether or not to outsource their tax preparation functions.
Fit for exploration: Practices that seek assistance with numerous accounting and tax tasks.
Before you start: Determine what types of reviews you provide; your seasonal capacity; any minimum commitment requirements you have; and the process for moving work through your practice management software.
3. Meru Accounting — White-Label Recurring Accounting
Meru Accounting provides a complete white-label solution to accounting services to CPA firms; including bookkeeping, reconciliation, reporting and compliance assistance.
The approach they have published focused on creating team structures that are dedicated; aligning work processes; working remotely together; and delivering the final product under the CPA firm's name. As such, this is an appropriate resource for those firms who are in the process of evaluating different providers for recurring bookkeeping services.
Firms looking for an accounting team that will work behind the scenes and aligns with their processes can find them at Fit To Explore.
Prior to Beginning: Ask for a sample of the work papers; find out what types of access the reviewer will have; verify the specific US tax preparation tasks to be performed by the client, as opposed to assuming that those are part of your bookkeeping services.
4. TOA Global — Dedicated Accounting Talent
TOA Global provides a solution to the accounting professional shortage faced by companies; providing solutions such as recruitment, employee support, training and professional development.
How much of the delivery management function does your practice retain? Firms with documented processes and manager(s) who are able to lead the team may find it beneficial to add dedicated staff.
The "fit to explore" practice of developing an offshore team as part of your company's current business operations is one way to create a long-term offshore team.
Before you begin: Verify that you have role-specific experience with bookkeeping and taxes, as well as confirm your work hours, the type of supervision provided to you, and who is responsible for reviewed quality.
5. Aone Outsourcing Solutions — Bookkeeping and Tax Preparation Support
Aone Outsourcing Solutions offers CPA firms and business owners the option of outsourcing their bookkeeping needs, along with the ability to outsource the preparation of their tax returns.
Its tax preparation services are designed to provide assistance with the preparation of both individual and business returns; work on federal and state levels; offer white-label support; and develop tax documents that can be reviewed by a certified public accountant (CPA).
Businesses are looking into the option of using a bookkeeping service, as well as finding ways to increase their capacity for tax season.
Prior to beginning: verify what types of returns are supported; determine whether the applicant has experience using tax preparation software; assess if the applicant is available during high volume times of year (e.g., tax season); establish turnaround time guarantees; and clarify how much of the work will be done by the preparer versus reviewed by another professional before filing.
6. indinero — Business-Facing Accounting, Tax, and CFO Services
indinero is a business that provides bookkeeping, accounting, tax, payroll, and cfo services.
Because that broader finance offering is relevant to the accounting services market, CPA firms must determine if the company's engagement model can be used by them to deliver services to clients using their brand. A service designed for businesses will not necessarily allow a firm to use it as a "white-label" provider of bookkeeping.
Fit to examine: Firms that require both accounting and finance services, as well as firms that are evaluating potential joint venture agreements.
Before Beginning: Make sure you can use white label products/services, have a relationship with the client, know where your boundaries are when communicating with them, and verify that the product/service is compatible with your business's existing processes.
How to Compare Outsourced Bookkeeping and Accounting Services
A provider's service list is only the starting point. For CPA firm outsourcing, the more useful question is: will this team make our work easier to review and deliver?
1. Define the white-label arrangement
Agree on who communicates with clients, whose branding appears on deliverables, and who handles missing documents. Put client relationship boundaries and confidentiality expectations into the engagement terms.
2. Examine workpaper quality
Ask for an anonymized sample close package. Look for reconciliations, supporting schedules, documented adjustments, unresolved questions, and evidence of review.
A completed task should leave a clear trail that your reviewer can follow.
3. Separate bookkeeping from tax preparation
Tax-ready books and prepared tax returns are different deliverables. Confirm whether the engagement includes trial balance preparation, tax workpapers, return preparation, review, or filing support.
Document each responsibility before tax season begins.
4. Check software and workflow fit
A provider may know QuickBooks or Xero without understanding your firm's naming conventions, close checklist, or approval process.
Accounting workflow standardization should cover document intake, task ownership, query tracking, review stages, and final delivery.
5. Evaluate communication and continuity
Identify your day-to-day contact and reviewer. Agree on response expectations, escalation routes, backup arrangements, and how workload changes will be handled.
6. Compare the full delivery cost
Assess onboarding, cleanup, software, review, revisions, and internal supervision alongside the quoted fee.
A useful comparison includes your team's time spent managing and correcting the work, not just the provider's invoice.
Start With a Defined Pilot
Before expanding an outsourcing engagement, test a small group of representative client files.
Set the scope and deadlines in advance, then assess:
Accuracy of reconciliations and supporting schedules
Completeness of the close package
Reviewer time and revision volume
Communication and query resolution
Delivery against agreed timelines
Use the results to refine the workflow and decide whether to increase capacity.
