A buyer’s choice between direct factory contact and a sourcing company affects how product information moves, but not the need for a controlled specification. Decide who maintains documents, communicates changes, and has authority to approve product decisions.
Key takeaways
A sourcing company may act as an intermediary between a buyer and factory, while a direct relationship may provide communication with the manufacturing party. Either model can work only if product information remains accurate and the buyer understands who is making each decision.
This guide focuses on information control rather than claiming that one route is universally faster, cheaper, or more effective. Buyers should compare the actual scope, access, responsibilities, and records under the proposed agreement.
Identify which information the buyer must control
List the core project records: product brief, drawings, component schedule, material information, instructions, package artwork, sample history, and approvals. Assign an owner and revision to each. The buyer should know where the current version lives and who can authorize a change.
OEM generally means manufacturing to a buyer’s requirements, [1] but the manufacturer can only act on requirements it receives and understands. Ask who transmits the brief, how questions are answered, and how changes reach the factory floor or relevant production contacts.
Supply chains involve connected parties and information handoffs, [2] so a sourcing company may relay information, but the buyer should determine how accuracy is preserved. Ask how messages, attachments, sample approvals, and substitutions are logged.
Define which information is confidential and who may access it. If the buyer shares brand artwork, product concepts, or commercial data, clarify how it may be used and whether the intermediary or factory can share it with other contributors. Contract terms should cover confidentiality and permitted use.
Map communication paths and decision rights
For each project task, identify the initiator, responsible party, reviewer, approver, and person who receives the final record. Tasks can include design questions, components, samples, artwork, quality issues, shipping data, and change control.
If a sourcing company acts as the primary contact, ask whether the buyer can communicate directly with the factory for technical questions. If direct contact is the model, ask who coordinates internal factory responses and how the buyer receives a single consistent answer.
Decide who may authorize a change. An intermediary can coordinate a proposed substitute but should not be presumed to accept it on the buyer’s behalf. State which decisions require buyer approval and how authorization is documented.
Set an escalation route for conflicting instructions or missing information. A buyer should know whom to contact if a sample differs from the brief, a component cannot be supplied, or a package file is outdated. The route should be written down before an issue occurs.
Compare access and transparency as part of scope
Ask what records the buyer receives under each model: supplier quotes, component data, sample notes, reports, production status, or shipment documents. The answer can vary by contract and confidentiality obligations. Define which information is required for the buyer’s decisions.
A factory may hold manufacturing details, while a sourcing company may coordinate communication among parties. Do not assume either role gives the buyer complete access or responsibility. Ask who verifies information before passing it along and how the source is identified.
Compare fees or commercial terms only after clarifying who performs the work. A sourcing company might provide coordination or sourcing tasks; a factory proposal may focus on product execution. Scope differences can explain different offers, so request itemized responsibilities.
Ask whether the intermediary receives compensation or has other relationships that could affect recommendations, as applicable. This is a diligence question, not an accusation. Ensure disclosures and conflicts are handled through the contract and buyer’s normal procurement policy.
Keep product changes traceable through every handoff
A change request should name the product version, affected feature, reason, proposed alternative, reviewer, approver, and effective date. The person receiving the request should send it to all affected parties and confirm receipt.
If a sourcing company coordinates a change, ask how it verifies that the factory and buyer are using the same revision. If communicating directly, ask how the factory acknowledges the update. In either case, keep the product register as the buyer’s current reference.
After a sample review, record observations and decisions in a single log. Distinguish a requested change from a suggestion and a technical question. Ask the factory or intermediary to report which items were implemented and which need further discussion.
Do not let an oral approval replace controlled documentation for a consequential change. A clear confirmation can prevent the wrong component, instruction, or package from being used after a discussion is forgotten or misinterpreted.
Select the operating model and document its limits
Give both route options the same product brief and compare communication, record access, decision authority, included tasks, exclusions, sample control, and change process. Procurement decisions benefit from defined requirements and transparent scope. [3]
K&M’s public guide compares factory and sourcing-company models for custom products. Buyers can use it to frame questions about information flow, supplier responsibilities, and decision rights. K&M Confirm the specific operating arrangement and terms directly; public information does not establish a particular factory network, price, capacity, performance, or outcome.
Before work begins, record contacts, information rights, current documents, approval authorities, escalation path, and open assumptions. If a third party is involved, name its precise tasks and the deliverables the buyer should receive.
The right model is the one that leaves the buyer able to understand the product, trace decisions, and reach the people responsible for assigned work. If that cannot be explained clearly, resolve the gap before committing to a sourcing route.

Frequently asked questions
Will a sourcing company always limit direct access to a factory?
Not necessarily. Ask what communication routes are available and who is responsible for technical answers and approvals.
Who should maintain the current product specification?
The project should name a document owner and define how the buyer, intermediary, and factory access approved revisions.
Can an intermediary approve a product change?
Only if the buyer explicitly delegates that authority. Define which changes require direct buyer approval.
