Capture the requirement
Submit exact part numbers, manufacturers, quantities and references through a structured BOM.
BOM & RFQ
Prepare multi-line component requirements for structured matching, sourcing review and quotation through one procurement workspace.
Availability, pricing, MOQ, packaging and lead time are confirmed for the specific quotation and proposed supplier source.
Live input workspace
CSV files are parsed in this browser tab. XLS and XLSX files can be shared after our sourcing team replies.
Upload a CSV, paste part lines or add a requirement manually.

FROM BOM TO SOURCING DECISION
High line counts should not create hidden assumptions. The workflow keeps input quality, sourcing decisions and supplier confirmation visible.
Submit exact part numbers, manufacturers, quantities and references through a structured BOM.
Part fields are organized so missing quantities, suffixes and manufacturer details can be identified.
Exact inputs, items needing clarification and alternative paths are separated for review.
Hard-to-find lines move into Chip-seek's Shenzhen and partner sourcing channels.
Supplier, commercial, timing and requested quality details are reviewed before the offer is issued.
Submitted BOMs may be processed with Chip-seek's internal part and supplier-matching tools. The sourcing team reviews the results and replies by email before any quotation or order is confirmed.
The review state separates complete inputs from unresolved part details and deep-sourcing lines. It does not present unconfirmed stock, price or lead time.
| Requested line | Input check | Qty | Procurement path |
|---|---|---|---|
| LINE 01 Exact MPN, manufacturer and package supplied | Exact input | 2,500 | Candidate supplier paths reviewed before quotation |
| LINE 02 Part suffix or package detail is incomplete | Needs review | 800 | Hold supplier recommendation until details are clear |
| LINE 03 No standard catalog path identified | Sourcing path | 300 | Shenzhen supplier candidates reviewed and verified |
| LINE 04 Alternative part may require engineering review | Needs review | 1,200 | Separate exact and substitute supplier paths |
DATA THAT SUPPORTS A DECISION
A BOM is more than a list of part numbers. Quantity, timing, packaging and acceptance needs determine whether a supplier option is commercially usable.
Chip-seek fulfills requirements through warehouse-held inventory and reviewed sourcing channels. Availability for each requested line remains subject to final quotation confirmation.
Clear boundaries make the workflow more useful for procurement and engineering teams.
The live workspace parses CSV files with manufacturer part number, manufacturer and quantity columns. You can also paste lines or add them manually. XLS and XLSX files can be shared with the sourcing team after the initial reply.
The line is kept separate for clarification or deep sourcing. Potential alternatives are not presented as exact matches and may require engineering approval.
No. Availability from warehouse-held inventory or reviewed sourcing channels, together with quoted quantity, pricing, MOQ, packaging and lead time, is confirmed for the specific quotation. A submitted BOM does not reserve stock.
Yes. Add these requirements to the RFQ so the proposed source can be reviewed against the acceptance criteria that matter to your organization.
Prepared CSV and pasted lines stay in the current browser tab until you submit the form. Submitted details are included in the business inquiry so Chip-seek can review and follow up on the requested quotation.
