ISO and bizSAFE Referral Partners, Singapore
Keep your client relationship.
Bring in the right expertise.
If a tender, customer audit or training need takes your client beyond your core service, ZES can assess the fit for ISO, bizSAFE, grant or training work. Choose a referral route or have us deliver the agreed technical scope behind your relationship.
Send your business, the clients you serve, the service needed and any deadline. We reply within one working day. After a short call, you receive a clear next step and the referral or subcontracting route that fits.
Since 2014, with Lead Auditor experience

From start to finish.The consultant you meet is the consultant who stays with your project.
When a client need sits outside your core service
Add specialist delivery without losing the relationship.
This is for firms that already advise, supply or train Singapore businesses and need a dependable specialist for certification, safety or grant-related work. It also gives procurement and L&D teams one point of contact when they are assessing external support.
A tender needs ISO or bizSAFE
Your SME client needs ISO 9001, 14001, 45001 or bizSAFE Level 3 and above for a tender, a main contractor or a customer audit.
A procurement team needs a capable delivery partner
You are shortlisting a consultancy for a defined certification, safety, grant or process project and need to understand who will do the work.
An L&D team needs practical external training
You need ISO awareness or related capability support that fits the work your people actually do, with a clear scope and project contact.
Your firm wants to widen its offer
Corporate secretaries, accountants, IT vendors, agencies, HR and training providers, and consultants can refer a suitable need without building an in-house ISO or bizSAFE team.
Start with the facts. Send the business activity, headcount, sites, tender or customer requirement, deadline and the way you want to work together. For a referral, include the client contact when they are ready to be introduced. For subcontracting, include the scope you want ZES to cover.
Two ways to work with ZES
A referral route or delivery behind your relationship.
We start with the client need, not a standard package. First we check the fit, service scope and timing. Then we agree whether ZES works directly with the client as a referral or provides the agreed technical scope while you remain the client-facing partner.
- 01Send the need
Tell us what the client needs, why it is needed, the deadline, business activity and how you want ZES involved.
- 02Check the fit
We review the client profile, likely service scope, timing and whether a referral or subcontracting route is suitable.
- 03Agree the route
We set out who speaks to the client, what work ZES covers, what information is needed and the referral terms where applicable.
- 04Scope the project
After the client discussion, we confirm the project scope, responsibilities, documents or training required, timeline and quote.
- 05Keep you informed
For a referral, we update you as the engagement progresses. For subcontracting, we work to the agreed reporting and client-contact arrangement.
A clear basis for working together
The client need, scope and route are clear before work begins.
A partnership should be easy to explain to your client and easy to run. The exact documents depend on the service and model, but the first discussion gives both sides a practical record of the project in front of you.
- Fit check covering the client, requirement, timeline and delivery route
- Service recommendation for ISO, bizSAFE, grant, training or agreed digital work
- Clear referral terms for an eligible client introduction
- Written project scope, quote and timeline after the client discussion
- Named project contact and agreed client-contact arrangement
- List of documents, site information or staff input needed to begin
- Referral progress updates or subcontracting reporting, as agreed
- Confidentiality arrangements, including an NDA on request
| What we check | What you send | What we confirm | Next step |
|---|---|---|---|
| Client requirement | Tender, customer request or training need | Relevant service and likely scope | Short fit call |
| Timing | Deadline, expiry date or project start | Whether the timing is workable | Project timeline |
| Working model | Referral or subcontracting preference | Client-contact and delivery arrangement | Terms and quote |
Referral terms and project scope
Clear terms before you introduce a client.
fee
For an eligible referral, you earn a referral fee on every closed client. For subcontracting, the commercial arrangement follows the agreed technical scope and client-contact model. We confirm the route before either side commits to the project.
The first discussion confirms
- Whether the client and requirement are a fit for ZES
- The referral or subcontracting model that suits the relationship
- Who owns the client communication and project coordination
- The scope, quote and timeline to be confirmed with the client
- The referral terms that apply to an eligible closed client
Referral fees and subcontracting terms depend on the service, client need and agreed role. Ask us before making a commitment to your client.
From introduction to project scope
A fit check first, then a clear project route.
We reply within one working day with the next practical step. The project timeline then depends on the service, client readiness, sites, documents and any tender or customer deadline. We confirm a realistic timeline after the fit check and client discussion.
What helps us assess the fit
- The tender, customer audit request or training brief is available
- You can share the client's business activity, headcount, sites and deadline
- The client knows whether it wants a direct referral or a subcontracting arrangement
- A decision-maker can join the first scope discussion
What can delay a clear answer
- The requirement or deadline has not yet been confirmed by the customer or main contractor
- The client has several sites, business units or activities to assess
- The technical scope needs more information before it can be quoted
- The client-contact arrangement has not been agreed between the parties
*We reply within one working day. A project timeline is confirmed after we understand the client requirement, scope, documents available and the working model.
Before we bring ZES into the conversation
What makes a partner introduction useful to the client.
The best introductions start with a real requirement and enough context to give the client a straight answer. We check these points before recommending a service or confirming a subcontracting arrangement.
The requirement is specific
We identify whether the need comes from a tender, customer audit, certification goal, staff capability gap or process project. That tells us which service may fit.
The deadline is known
Tender dates, certificate expiry dates, audit dates and training dates affect what can be scoped and when the work can start.
The business context is available
Activity, headcount, sites, existing certificates and the client requirement help us assess the likely scope before anyone promises an outcome.
The client relationship is respected
We agree whether ZES is introduced directly, works behind your relationship or joins a procurement process, before discussing the project in detail.
The scope has an owner
The client needs someone who can provide documents, arrange site access or staff sessions, and confirm the facts in the project scope.
Confidential information stays protected
Partner and client information is used to assess and deliver the work. We can sign an NDA where required.

Partnership questions
The referral route, subcontracting and client fit.
Short answers for firms, procurement teams and L&D leads assessing ZES as a delivery partner. Send the requirement and deadline if you need an answer on a specific client opportunity.
Who can partner with ZES?
We work with corporate secretary firms, accountants and bookkeepers, IT vendors and systems integrators, marketing agencies, HR and training providers, consultants, procurement teams and other firms that serve Singapore businesses. The key question is whether the client need fits our ISO, bizSAFE, grant, training or agreed digital work.
What is the difference between a referral and subcontracting?
With a referral, you introduce an eligible client, ZES checks the fit and delivers the engagement directly. You stay focused on your core work and earn a referral fee on every closed client. With subcontracting, you remain the client-facing partner and ZES provides the agreed ISO, bizSAFE or grant technical scope behind your relationship.
Which services can I refer or subcontract?
ZES provides ISO 9001, 14001, 45001, 27001, 22000, 50001 and 41001 consultancy, bizSAFE Level 3 and above, grant application support, ISO awareness training, AI Implementation & Process Redesign, and agreed Shopify migration or store-build work.
Do you offer referral fees?
Yes. When you introduce an eligible client, we assess the fit, discuss the service and deliver the engagement. You earn a referral fee on every closed client. We explain the terms before the client is introduced or the project is committed.
Can ZES work under our name?
Yes. Under a subcontracting arrangement, you can lead the client relationship while ZES provides the agreed ISO, bizSAFE or grant technical scope. Before work begins, we agree the scope, client-contact arrangement, information needed and project reporting.
What should I send for a fit check?
Send your business name, the clients you serve, the client's industry and activity, headcount, sites, the service or requirement, deadline, existing certificates if relevant, and whether you prefer referral or subcontracting. A tender, customer request, audit notice or training brief helps us assess the fit faster.
How do you protect client confidentiality?
We treat partner and client information as confidential and use it to assess and deliver the work. We can sign an NDA where required. We also agree the client-contact arrangement before detailed project discussions begin.
Can a procurement team engage ZES directly?
Yes. Send the scope, supplier requirements, procurement timetable and decision process. We will confirm whether the work is a fit, what information is needed to quote and who will lead the project. An independent auditor or certification body audits and certifies ISO and bizSAFE work. ZES prepares the business for that process.
