A country marked as covered is a map entry, not an engagement. When your client's filing deadline sits in another jurisdiction, the only question that matters is which local entity will actually do the work.
In this article, we discuss international accounting network local firm verification before any referral. We cover member and non-member delivery and who signs the international engagement letter. We also set out the cross-border checks we recommend running first.
What Does Coverage by an International Accounting Network Actually Confirm?
A country listing confirms that a route into the jurisdiction exists; it does not confirm which firm will serve your client, under what status, or for which service.
Coverage pages answer one question: can the network reach that market. They do not identify the legal entity that will contract. They also do not confirm its status or its ability to perform your client's specific service. That gap matters most when a filing deadline, licence application or regulator submission is involved.
3E's public Worldwide Office page describes 3E as a brand used by a network of independent accounting and consulting firms, with each member firm a separate and independent legal entity. 3E's published membership criteria refer to professional and ethical standards, good regional standing, and membership of the relevant local professional accountancy institute. This description covers member firms; it should not be extended to other provider categories without checking the network's current policy.
Beyond membership, our professional judgement is simple: treat any country page as a starting point, not a confirmation. Before relying on coverage, obtain written confirmation of the local provider's name, legal entity, office, service scope and contracting role. We recommend this as a verification step. It does not mean every country listing has limited scope. Confirm the exact position with the network when needed.
How Do Member and Non-Member Delivery Routes Differ in Practice?
The key distinction is confirmed membership versus a provider whose status is not confirmed; the latter calls for additional matter-specific checks.
3E's public pages describe member firms. They state that each member firm is legally separate and independent. They also refer to professional and ethical standards, good regional standing, and membership of the relevant local professional accountancy institute. The public material reviewed does not establish formal categories or criteria for other providers.
For that reason, ask the network to confirm the local provider's status in writing. Ask it to name the legal entity, office, service scope and contracting role. If the provider is not confirmed as a member, carry out additional matter-specific checks before presenting it as suitable.
What changes in practice is the level of confirmation required before referral. It is not a presumed global signing structure. The local entity named in the engagement letter should sign for its agreed work. Any coordination by another firm should have a separately defined scope.
Coverage Claims Versus Written Confirmations
| What the listing shows | What it may confirm | What to confirm in writing |
|---|---|---|
| Country marked as covered | A route into the jurisdiction exists | The exact legal entity that will contract and invoice |
| Network brand on the page | The brand operates internationally | Whether the provider is a member firm or another category |
| Service named for the country | The service is generally available | Scope, exclusions, licences and who performs the work |
| Contact details listed | An office exists | Named engagement contact and current capacity |
Who Signs an International Accounting Engagement Letter?
The local firm performing the work issues and signs the engagement letter; the network brand does not contract for the local service.
In cross-border engagements, identify the signing firm clearly. The local entity named in the engagement letter should accept the scope and invoice for its own work. A network brand does not, by itself, identify the local service provider or contracting entity.
Where a referring firm adds coordination, consolidation or project management, that work should sit in a separate engagement letter or a clearly separated scope. Each firm then remains responsible only for the work it signed for. This is our recommended engagement structure, not a universal rule, and liability in any specific matter always depends on the documents actually signed.
Before signing, check that the letter names the exact legal entity, the office performing the work, the named engagement contact and any subcontractor involved. A letter that names only the network brand should be queried. For a deeper treatment of responsibility across borders, see our guide on who is accountable in multi-country accounting engagements.
What Belongs on a Cross-Border Referral Checklist?
A sound checklist confirms the contracting entity, licences, conflicts, capacity, scope, fees and data handling in writing, before the client is introduced.
A referral is only as strong as the checks behind it. The items below reflect the questions we work through before introducing any local provider to a client or referring partner. They are suggested due diligence rather than a fixed network-mandated form, and jurisdiction-specific requirements should always be confirmed with the relevant local regulator.
1. The Contracting Entity and Office
Ask which exact legal entity will contract and invoice, and which office will perform the work. Confirm registration and good standing independently rather than relying on letterhead.
2. Licences and Authorisations
Identify which requested services require a practising certificate, tax-agent status or a corporate-services licence in that jurisdiction, and who holds it. Requirements differ by country and by service, so verify against the regulator's current position.
3. Conflicts, Sanctions and Client Acceptance
Check that conflicts, sanctions and client-acceptance screening have been run against the client, its owners, directors and counterparties. Record any independence restrictions that apply.
4. Capacity and Comparable Experience
Ask whether the provider has performed the same service for a foreign-owned business in the same sector, and whether staff capacity exists now, including holiday coverage.
5. Scope, Documents and Dependencies
Record what is in scope, excluded, or dependent on another adviser. List the documents, translations, notarisation and signatures the client must supply, and who monitors deadlines.
6. Fees and Contracting Role
Separate professional fees, official charges and third-party costs, and confirm which can change. Agree what advance payment is required and who issues the engagement letter.
7. Data Handling and Subcontracting
Ask where client data will be stored and transferred, and whether any subcontractor will be used. Confirm who handles complaints and whether reporting in English is available.
Member Route Versus Non-Member Route in Practice
| Aspect | Member-firm route | Non-member or gap-filling route |
|---|---|---|
| Admission standing | Completed network admission with continuing obligations | Verified per matter, not under the full membership framework |
| Branding | May present itself as a network member | Must not be described to the client as a member |
| Engagement letter | Signed by the member's own local legal entity | Signed by the local provider, with its status stated to the client |
| Pre-referral checks | Membership-level due diligence already completed | Conflicts, licences, capacity and fees checked per matter |
| Escalation | Network-level escalation route available | Contractual remedies sit with the contracting provider |
Where Can You Independently Verify a Local Provider?
You can verify a local provider through the national business registry, the regulator or professional body, sanctions screening, and written confirmation from the network.
Verification should not depend solely on what the provider tells you. Public sources exist in most jurisdictions, and a provider that resists being checked in them is itself a warning sign.
1. The National Business Registry
Singapore's Accounting and Corporate Regulatory Authority (ACRA) operates the Bizfile portal. You can search for an entity and buy a Business Profile with registration details and information about position holders.
2. The Regulator or Professional Body
For regulated services, check the relevant authority's register of licence holders. A credible provider should be able to point you directly to its current listing.
3. Sanctions and AML Screening
Screen the entity and its principals against applicable sanctions lists. The FATF Recommendations provide an international framework for combating money laundering, terrorist financing and proliferation financing.
4. Written Confirmation From the Network
Ask the network to confirm the provider's status, the contracting firm and the service in writing. A reply that says only that the country is covered does not answer those questions.
Deadline Red Flags and Safer Responses
| Red flag | Safer response |
|---|---|
| The contracting entity is not named | Request the exact legal entity and verify it in the registry |
| No verifiable licence listing | Ask for the regulator's register entry and check it yourself |
| Scope, fees or timetable described only verbally | Require a written scope and fee estimate before introduction |
| Capacity unconfirmed during holiday periods | Confirm named staff and coverage in writing |
| Documents or approvals still outstanding | Do not promise the deadline; agree a revised timetable |
When Is a Route Unsuitable for a Hard Deadline?
A route is unsuitable when the provider, the authority's requirements, the documents, the capacity or the timetable cannot be confirmed before the deadline.
For time-sensitive matters, do not promise completion until these points are confirmed:
- the provider
- the authority's requirements
- the documents
- the capacity
- the timetable
Registries and regulators can delay matters regardless of how capable the provider is, so cautious phrasing is professional practice, not pessimism.
Red flags include reluctance to name the contracting entity, no verifiable licence listing, scope and fees described only verbally, and capacity that cannot be confirmed in writing. Where the engagement involves cross-border workforce or payroll support, providers experienced in global mobility services will flag host-country registration issues early, which is a useful signal of competence.
If the first route fails, clients may discuss these options with their advisers:
- another qualified local provider
- splitting the work between appropriately qualified providers, such as a local law practice for formation and a corporate services provider for tax and bookkeeping
- revising the client's timetable
They are not a fixed sequence. For planning context, our corporate setup benchmarks 2026 review typical incorporation timelines, costs and compliance across key jurisdictions.
Conclusion
Coverage is a starting point, never the engagement itself. Confirm the local provider's membership status and role before relying on a referral. Written confirmation of the provider's name, legal entity, status, scope and contracting role closes that gap.
We approach each cross-border referral with documented checks:
- registry and licence checks
- conflicts and sanctions screening
- capacity and deadline testing
- a signed engagement letter naming the performing entity
Where a member route is unavailable, we say so and work through the alternatives with you. We do not imply a guarantee the map cannot support.
As a member firm of the 3E Accounting International Network, we help clients and referring partners verify the local firm behind each engagement before commitments are made. If you are planning cross-border work, verify the local firm before commitments are made. We would be glad to assist.
Check the Local Firm Before You Commit
Tell us the country and the service you need. We will confirm the local provider, its status and the contracting arrangement in writing before anything is promised.
Frequently Asked Questions
Not necessarily. A country listing shows that a route into the jurisdiction exists; it does not confirm which entity will contract, its status, or its ability to perform the specific service. Always obtain written confirmation before relying on coverage.
The local firm performing the work normally issues and signs the engagement letter, and it carries responsibility for that work. If a referring firm provides coordination, that should sit in a separate engagement letter or clearly separated scope.
Ask for written confirmation of the provider's status, legal entity, scope and contracting role. 3E's public pages describe member firms, but the status and suitability of any other provider should not be inferred from a country listing. The local firm signs for its own work, while a provider not confirmed as a member should receive additional matter-specific checks.
You can purchase the entity's business profile through the BizFile+ portal operated by ACRA to confirm registration, status and officers, then check the relevant regulator's register for any licences the requested services require.
No. A prudent provider will not promise completion until the local provider, the authority's requirements, the documents, the capacity and the timetable are all confirmed. Registries and regulators can impose delays outside any provider's control.
