Requirement Breakdown
We organize reference images, sizes, materials, colors, packaging, and use cases into requirements suppliers can understand.
From product idea to reviewable sample
Product Development & Sampling
When a product is still an idea, reference image, or rough requirement, Greetbuy helps communicate specifications, materials, samples, and revisions with Chinese suppliers.
How We Move Product Development Forward
Built for customers with a clear product direction who need supplier communication, sample follow-up, photo feedback, and later purchasing support in China.
Supplier Matching and Communication
We look for suppliers that may support development or sampling and discuss feasibility, cost, timeline, and MOQ.
Sample Purchasing and Follow-up
We help order samples, follow production or delivery progress, and provide basic photos after samples arrive.
Revision and Purchasing Connection
We continue supplier communication based on your revision notes and connect approved samples to formal purchasing and fulfillment.
What an Actionable Sampling Brief Should Include
Suppliers need clear, verifiable information to assess feasibility, quote accurately, and make samples. Together, these items form the basis for sampling and acceptance.
Product Use and Target Users
Describe use cases, target users, core functions, and the problem to solve so the supplier understands the design direction.
Specifications and Acceptance Criteria
Define dimensions, materials, structure, performance, tolerances, and basic test methods to align the meaning of an acceptable result.
Appearance and Packaging Files
Provide colors, finishes, logos, labels, packaging format, and references, marking what must remain fixed and what may change.
Cost, Quantity, and Compliance Boundaries
State the target cost, sample budget, expected quantity, target market, and required certifications or safety standards.
Timeline from First Sample to Approved Sample
After the first sample is completed, each round addresses only recorded and approved issues, preserving versions and decisions until the sample and specifications can guide purchasing.
First Sample Inspection
Compare appearance, dimensions, structure, and basic functions with the sampling brief, then organize photos, videos, and measurements.
Difference and Issue Log
Separate nonconformities, items awaiting confirmation, and acceptable differences so verbal feedback is not lost or mixed.
Customer Feedback Approval
The customer confirms what to keep, revise, or accept, creating an itemized revision list the supplier can execute.
Revised Sample Review
Review the changed items and related effects when the revised sample arrives, then start another round only if needed.
Approved Sample and Specification Lock
The approved sample, specifications, materials, colors, and packaging become the reference for bulk purchasing and later inspection.
Sample rounds, costs, and timelines depend on product complexity and revision scope. Bulk purchasing does not begin without customer approval.
Product Development Process
Submit Idea and References
Send reference images, target function, materials, size, budget, estimated quantity, and target market.
Check Suppliers and Feasibility
We discuss whether suppliers support sampling, customization scope, sample cost, MOQ, and estimated lead time.
Sample Production and Warehouse Feedback
After samples are made, they can be sent to our warehouse for basic check, photos, and your confirmation.
Revise or Move to Purchase
If revisions are needed, we organize feedback. If approved, we move into purchasing, inspection, storage, and shipping.
Important Notes
Development results depend on supplier capability, completeness of requirements, sample budget, and revision rounds. One-time sample success cannot be guaranteed.
We assist communication and follow-up, but do not replace industrial design, structural design, certification testing, or intellectual property legal review.
For patents, trademarks, certifications, special materials, or safety standards, professional confirmation is recommended before development.
Best Fit
Customers with product ideas or reference images but limited China supplier communication experience.
Teams that want to sample in small batches before formal purchasing.
Projects needing sample follow-up, photos, revision notes, and fulfillment support.
Turn a Product Idea into a Practical Sampling Plan
Send reference images, specifications, and target quantity. We will help judge the next step based on supplier feedback.
