Alternative practice structure, or APS, is an arrangement in which an attest firm is closely aligned with a separate organization providing other professional services, with distinct ownership, operating agreements, and professional responsibilities.
What does an APS separate in an accounting transaction?
It separates defined business and professional-service entities. It does not make the client relationships, independence questions, or operating economics disappear.
The current AICPA Code of Professional Conduct addresses APS arrangements in its independence and organization interpretations. Its examples include separately conducted attest and nonattest operations. The Code reviewed for this page is updated through September 2026; apply the relevant provisions and effective dates rather than relying exclusively on an earlier transaction announcement.
A transaction can involve investment in a nonattest organization while an appropriately owned CPA firm continues regulated report services. The actual permitted ownership, control, and firm authorization require jurisdiction-specific review.
Use the valuation hub to connect the organization chart with price and cash flow. A consolidated revenue headline is insufficient if some fees belong to a professional entity the purchaser does not own in the same way as the acquired business.
Why must ownership and professional control be reviewed separately?
Economic participation, voting authority, employment reporting, and professional decisions can differ. Review all of them rather than assuming the shareholder percentage describes complete control.
Identify who owns each entity, elects managers, approves budgets, hires professionals, and makes engagement decisions. A management services agreement may influence staffing and resources even when another entity issues the attest reports. Counsel and professional leadership should evaluate whether the arrangement preserves required authority and responsibility.
The Illinois regulator’s public accounting page provides separate firm-licensing and managing-CPA resources. That illustrates why the entity and responsible professional need their own review. It does not establish that one Illinois process or ownership model works in every Midwest jurisdiction.
Read non-CPA ownership rules before assuming an investor can acquire every entity on the chart. Review permitted owners, financial interests, voting rights, participation conditions, and names under the applicable state rules. Document the conclusion for the actual buyer rather than for a hypothetical qualified purchaser.
How should the operating agreements be examined?
Examine the services, fees, responsibilities, renewal terms, and termination rights connecting the entities. Those agreements can determine both profitability and continuity.
List shared employees, office space, technology, administrative support, branding, and client-service workflows. Determine which entity pays each expense and which bills each engagement. A fee flowing between entities may transfer economic benefit while leaving professional responsibility elsewhere. The earnings bridge should show those flows clearly.
Ask what happens if the management agreement ends, the investor sells its interest, or a required professional leaves. Does the attest entity retain the staff and systems needed to complete engagements? Can the nonattest organization continue serving clients without the affiliated CPA firm? These dependency questions belong in operational diligence.
Check amendment powers and dispute remedies. An agreement adjustable unilaterally by one party can change the seller’s retained economics or the professional firm’s resources. Review foreseeable scenarios using the actual provisions rather than assuming commercial cooperation will always continue after ownership changes.
What does an illustrative entity cash bridge show?
It shows why intercompany fees must be reconciled before presenting combined earnings. The following numbers are illustrative assumptions, not an observed APS transaction or required arrangement.
Assume the professional entity earns $500,000 in external report-service revenue and pays $360,000 for shared personnel, systems, and support. The nonattest entity earns $1,300,000 in external client fees plus that $360,000 internal service fee, and incurs $1,280,000 of total operating costs. The professional entity has another $80,000 of direct costs.
| Component | Professional entity | Nonattest entity | Combined external economics |
|---|---|---|---|
| External revenue | $500,000 | $1,300,000 | $1,800,000 |
| Internal service fee revenue | $0 | $360,000 | Eliminated |
| Internal service fee expense | $360,000 | $0 | Eliminated |
| Other operating costs | $80,000 | $1,280,000 | $1,360,000 |
| Simplified earnings | $60,000 | $380,000 | $440,000 |
The combined calculation is $1,800,000 − $1,360,000 = $440,000. Adding both entities’ reported revenues without eliminating the internal fee gives $2,160,000 and overstates external revenue by $360,000. Adding their properly calculated profits does not create that revenue duplication, but the buyer must still define which economics it actually acquires.
If the purchaser acquires only the nonattest entity, its analysis must examine the service agreement supporting the $360,000 internal fee and all related costs. It cannot describe the $440,000 combined earnings as its wholly acquired return without explaining the professional entity’s ownership and obligations.
Why does independence require more than a separate entity name?
Relevant relationships can extend through employees, owners, affiliated organizations, and clients. The organizational split is a starting fact for analysis, not a blanket independence exception.
Map financial interests, employment roles, service relationships, and client overlaps. A platform’s other investments can require additional review where they intersect with attest engagements. Determine which standards and regulators apply, including rules outside the AICPA Code when relevant. Keep the independence assessment with the actual engagement and entity information.
Read attest versus non-attest services for service classification. A company receiving both accounting support and an audit presents different questions from a tax-only client. Label those combinations and review them before relying on consolidated cross-selling assumptions.
Track rule changes and effective dates. The reviewed Code includes recent firm-merger guidance and provisions with later effective dates. Have professional advisors identify what applies at closing and during the future engagement period. An old description of how another platform operated does not establish the purchaser’s compliance today.
How does an APS affect the seller’s retained role and equity?
It can place employment, rollover investment, and professional ownership in different entities. The seller should understand each position’s rights and liabilities independently.
Identify which entity employs the seller, which issues any retained equity, and which entity the seller must professionally manage or own. Cash at closing, contingent price, wages, distributions, and future equity value should have separate schedules. A buyer should not imply that professional ownership carries the same liquidity or governance as platform investment equity.
Examine transfer restrictions, mandatory repurchase provisions, valuation methods, capital calls, and departure terms. A seller planning retirement needs to know what happens to required professional ownership when they stop practicing. A seller remaining for several years needs a clear duty, compensation, and succession plan.
The rollover equity definition helps separate reinvested purchase consideration from operating compensation. The seller’s tax and legal advisors should review both the rollover mechanics and any retained professional interest before comparing the offer with an outright practice sale.
What do buyers and lenders need to underwrite?
They need the acquired entity’s actual cash rights, service dependencies, permitted authority, and continuing costs. A platform-level presentation does not answer every entity-level financing question.
Review cash collection, bank accounts, distributions, management fees, and debt obligations. Determine whether one entity guarantees another’s debt and whether restrictions limit cash movement. Earnings may exist in the combined model while remaining unavailable to service debt at the borrowing entity.
The NASBA announcement of the ninth UAA edition describes the Uniform Accountancy Act as a model adopted by individual jurisdictions. This reinforces checking enacted state requirements rather than treating a model provision as operative law everywhere. Track the states where offices, professionals, and clients create relevant obligations.
Lenders should review the actual organization chart and agreements early. Their financing requirements may affect guarantees, borrower identity, collateral, and permitted consideration. Resolve those issues before assuming a term sheet finances the entire proposed arrangement. Buyers should keep the professional feasibility and cash model aligned throughout negotiations.
Which diligence sequence makes the APS understandable?
Create one entity-by-entity record linking ownership, authority, client engagements, and economics. The point is to make the arrangement reviewable before documents become binding.
- Draw the ownership and governance chart, including retained seller interests.
- List each entity’s clients, services, licenses, employees, and professional responsibilities.
- Review management and shared-service agreements, fees, and termination consequences.
- Complete applicable independence and state-law analysis with qualified advisors.
- Reconcile external revenue, intercompany amounts, borrower cash, and seller proceeds.
Review the agreements and professional obligations with the transaction attorney and responsible CPA. Entity boundaries should explain the operating model and acquired cash rights.
A few common questions
What else should you know?
Does an APS allow a non-CPA to own the audit firm?
Do not infer ownership permission from the structure’s name. The actual attest entity must satisfy applicable state ownership and professional requirements, alongside relevant ethics standards. Investors may participate through a separate nonattest business, but the specific arrangement needs review of ownership, authority, services agreements, and independence before closing.
Can an APS have one public brand?
Branding may be shared subject to applicable rules, but clients and reviewers still need to understand which entity provides each engagement. Confirm naming, holding-out, contractual, and professional requirements. A common logo does not merge the entities’ ownership, licenses, reporting duties, or financial obligations into a single legal business.
Should the buyer value combined revenue from both entities?
Only after identifying the transaction perimeter and eliminating intercompany amounts. Combined external economics may help analyze the operating system, while the buyer acquires different rights in each entity. Show the actual acquired cash flows, continuing service agreements, professional costs, and retained interests instead of treating every consolidated dollar as wholly purchased revenue.
What if the seller retires from the professional entity later?
The agreements should address professional succession, ownership transfer, required qualifications, service continuity, and any repurchase of retained interests. Those mechanics can differ from departure from platform employment or rollover equity. Review the retirement scenario with professional and legal advisors before accepting an ongoing role that the seller may not sustain.
