Send a part number or a short description. A free first conversation checks fit, availability and any procurement requirements. You then receive a proposed scope, deliverables, fee and dates before deciding on paid work.
Buying through a company? Check eligibility first.
Jerry currently provides this service as an individual under the AmpSheen name. Before detailed project work, check that your company can engage an individual service provider. State any company-only contracting or specific tax-invoice requirement at first contact.
Items to confirm before any paid appointment
- Contracting and receiving-party names, and whether they match your vendor records.
- An approved payment method, currency and any payment-processing requirements.
- The invoice or receipt format your finance team requires, and the onboarding documents that can actually be provided. Do not pay until these are confirmed in writing.

What these review fees cover
Supplier counts are contact limits, not a promise of qualified candidates or allocation. Technical reviews assess documents and propose validation; they do not include physical testing, certification or a guarantee of drop-in compatibility.
For components already selected
Order coordination
One supplier, one purchase order and one shipment: agreed order terms, progress follow-up and shipping-document coordination.
Fixed US$200 is the starting choice for the one-supplier, one-order, one-shipment scope shown here. A higher goods value alone does not change an agreed fixed fee.
When can a percentage fee apply?
Alternative by written agreement: 3% of component value, minimum US$200 per order. Consider this for an ongoing order-linked assignment whose coordination scope changes with the order. The quote names the included work, value basis and any cap; both parties choose before work starts.
Before approving an increase in order value, review the coordination fee too. If the work is unchanged, agree whether to retain a fixed fee or apply a cap. A percentage is never added to the same work already covered by a fixed fee. Sourcing and technical reviews have their own scope.

Discuss supportAdditional work agreed before it begins
Ongoing purchasing support
Up to 15 hours each month for agreed supplier communication, document follow-up and purchasing coordination.
Hours, availability and renewal terms
Monthly terms define unused hours, availability and any overage before renewal.
US$750per month
Discuss supportPayment, credit, expenses and changes
Payment by stage
The US$200 first review is paid before work starts. Larger projects normally use 50% on appointment and 50% on agreed delivery. Monthly support is paid at the start of the agreed month. Your proposal confirms the dates and revision allowance.
Credit for work already completed
When a first review expands into the same sourcing project, overlapping work is credited. A US$200 review that fits within the US$500 scope leaves US$300 to pay. The same work is never billed twice.
Third-party costs are separate
Samples, laboratory testing, certification, freight, duties and agreed travel are outside these fees. Expenses need your approval in advance. Any applicable tax on the service is identified in the written quote.
Clear completion and change terms
Delivery means completing the agreed work and explaining the findings, including exclusions or an absence of suitable candidates. Unanswered requests are recorded. A pause or cancellation is settled against completed stages; extra parts, follow-ups or shipment stages require an agreed change.
What should the service improve?
- Price: compare total purchasing and validation cost.
- Continuity: assess a second source and its qualification gaps.
- Technical risk: identify evidence that could stop a purchase.
- Team time: agree the communication and follow-up work to hand over.
Illustration only: a US$900 fee spread over 20,000 parts requires US$0.045 per part in first-year savings just to recover that fee. Samples, validation and other added costs increase the hurdle. This is not a quote or a predicted saving.
If you only need a small spot quote for an approved part, direct supplier contact may be more economical. Use the free first conversation to decide whether a paid review has a worthwhile question to answer.
Deliverables when evidence is missing or delayed
What an unanswered enquiry must still show
The handover records why each supplier was selected, contact channel and date, follow-up or escalation, responses and evidence references, unresolved questions, and the reason for stopping. It also recommends whether a further route is worth the added cost. The contact limit bounds the scope; sending the stated number of messages alone is not the completion criterion.
Agree two dates before paying
The proposal states the initial review delivery date and the cut-off for supplier evidence separately. Work starts after the required inputs, scope and agreed starting payment are complete. It lists missing inputs, follow-up limits and how delays are reported. A supplier delay does not silently move the initial review date; a change needs agreement. Ask for current availability in the free first conversation.
Supplier payments and independence
You pay suppliers directly.
AmpSheen charges you separately for the agreed work. These services are client-paid, without undisclosed supplier commissions. Any proposed supplier-linked payment needs separate written disclosure and your agreement before acceptance.
Inspect the handover for your stage
These examples explain how the work is documented. Your proposal ties the selected service to the part numbers, sources, questions and delivery date for your project.
01
Check a proposed supply route
You have a part number or a seller’s quote.
US$200: one specified part, up to 2 supplier contacts. US$500: 1–3 related parts, up to 5 contacts. The proposal identifies which route checks fit that allowance.
Discuss this task- You receive
- A route record, document checklist, commercial comparison basis and unresolved questions.
Inputs, work, completion and exclusions
- Starting material
- One part number, intended quantity and the quote or source you want assessed.
- Work included
- One seller/route; trading identity and any claimed authorisation; requested lot documents; quote terms; one clarification round with the seller.
- Completed when
- The agreed checks and follow-ups are recorded, including unavailable documents or unanswered requests, and the report is explained in one client clarification round.
- Separate scope
- Physical authenticity testing, factory audits, legal opinions and a guaranteed supply allocation.
02
Compare candidate components
You have an incumbent part and want a second source.
From US$900: one defined application and up to 3 candidates. Includes a proposed validation plan; sample purchases, test execution and continuing coordination are separate.
Discuss this task- You receive
- A comparison matrix, exclusion reasons, a source index and a go / hold / stop recommendation for the next stage.
Inputs, work, completion and exclusions
- Starting material
- One incumbent or a defined requirement, application conditions and the parameters that cannot change.
- Work included
- Up to three candidates for one function; nominal and condition-specific differences; document gaps; one proposed sample plan.
- Completed when
- Each candidate has a reasoned disposition and each material unknown has a next action. One clarification round is included in the example scope.
- Separate scope
- A guarantee of drop-in compatibility, redesign, purchased samples and laboratory or certification fees.
03
Build a brief and coordinate evaluation
You know the application, or have a candidate ready to evaluate.
Requirement analysis may sit within the US$900+ review. Ongoing sample coordination can use US$750/month, up to 15 hours, or a separately scoped fixed assignment. US$200 order coordination covers an already-selected part, not technical evaluation.
Discuss this task- You receive
- A supplier-ready brief, sample/lot register, evaluation schedule and an issue log with owners and next actions.
Inputs, work, completion and exclusions
- Starting material
- Use conditions, the circuit owner’s acceptance criteria and the questions that samples must answer.
- Work included
- One component family and one agreed sample round; organise the requirement sheet, supplier questions, sample identifiers and testing responsibilities.
- Completed when
- The agreed coordination tasks and received results are documented; delays, missing results and outstanding decisions are handed over explicitly.
- Separate scope
- Running an independent laboratory, signing a product certification or approving your design for production.
From first note to a usable handover
- 01
Describe the task
A part number or a short description is enough for first contact. The initial reply target is two working days: Monday–Friday, UTC+8, excluding mainland China statutory public holidays. Weekends are excluded even when designated as make-up working days. This is a general-enquiry target, not an emergency procurement commitment.
- 02
Agree the stage
Jerry confirms fit and availability, asks the essential questions and sends the proposed scope, fee, schedule and completion criteria. No paid work starts without agreement.
- 03
Work from a shared record
The project uses a dated source list, question log and decision record. Agree the update rhythm and flag a blocked item instead of silently extending the work.
- 04
Review and hand over
Receive the agreed files and open issues. Clarify the report, then decide whether to stop, collect more evidence or commission the next stage.
Responsibilities, availability and specialist work
What I take responsibility for
Within the agreed scope: record where information came from; distinguish supplier statements from independent results; show material differences and missing evidence; keep the issue history; and correct a substantiated error in my deliverable. The proposal sets any wider revision allowance. Supplier approval, design acceptance and the purchase remain yours; those decisions should be supported by a record you can inspect.
Working directly with Jerry
Jerry is the service contact and project lead. Before accepting work, the proposal confirms availability, communication hours and the update schedule. Planned absences and a handover date are discussed in advance. Project notes and deliverables can be handed over in ordinary files; no substitute is given access to your information without agreement.
Where the work is strongest
Materials-informed component comparison, MLCC/passive-component requirements, reliability-document review and communication with Chinese manufacturers. Inductors and power-device sourcing can include supplier and test coordination; specialist circuit design, safety approval and laboratory execution need the appropriate engineers or providers agreed for that project.
