Service for Propagate

1. RISKS Designer must understand the risk of productize a prototype. Seeed will help to make sure a smooth process but risks like BOM defect, Manufacture loss, communication gaps or any other unexpected issue might lower the yield remarkably. Seeed will cover the manufacture cost for defect units, but couldn’t take the responsibility of material or any incurred loss.
2. TERMS Sample – A validated working sample shipped to SEEED
BOM – The bill of material needs precise part name, product ID in major distributor, and verified stock
PCB File – Gerber file or Eagle file, with requirements
Test Plan – Step by step straightforward guide to validate manufactured products
NPI – New product integration
ROI – return of investment

5. Eagle design rules file and Eagle libraries we are using.
Bill of Material is the key factor for a successful PROPAGATE case, we will do our best to communicate and help. But please beware the risk of fake, lead time, out of stock, model confusion and etc. The preferred way is using popular components, prepare alternatives and plan ahead.

In anyway, please estimate the BOM cost for a quotation session, we will reply with a precise quotation in Invoice session before your payment. 7. ASSEMBLY NOTES
We prefer to help test and follow up any quality issue on the first sight. Please provide a simple and effective test plan of step by step instruction. We will make sure manufactured products will pass the test plan with expected results. A test report will be provided upon test finish.
Sample Test Plan -Kevin
Default repair on defect units, recovered units will be counted as accept quantity, defect units reserved for 2 months, could be shipping back to designer or discard. NPI Target 90% pertentage, carry out defect analysis if yield lower than 90%, try recover defect units if yield higher than 90%. Repeated production will target 95% yield.
Initial Balance = Deposit - accepted product quantity * Unit cost
- Deposit: After quotation is confirmed, our project manager will send out an invoice. A deposit is needed to initiate new product introduction (NPI). Designer also needs to send an email with following info to to confirm payment:

- Accepted product quantity: Designer will decide target quantity, Seeed start manufacture with target quantity and notify yield on batch ends. Due to manufacture loss, accepted product quantity might be less than target. Designer should understand the manufacture risk especially for NPI units. For defect units, Seeed will keep sample and corresponding evidence for review; try to fix, but not taking the responsibility of BOM cost. Seeed will cover corresponding cost of mass defect (over 20%) caused by soldering and PCB.
- Unit cost will base on target quantity, even if the accepted product quantity does not meet corresponding price break.  


Current Balance = Sales Qty * Unit Price * (1- handling fee) + Previous Balance + 10% of Designer Purchase compensation
- Sales qty will be calculated each month via bazaar system. Every sales order is archived for review. - Unit Price will be decided by customer.
- Handling fee includes Paypal/TT/Credit card cost, storage, order handling, logistic, post-sales support, web-store (Bazaar) catalog listing, and shipping loss.
- Designer purchase: Designer could allocate inventory by placing orders in Bazaar. For drop-shipping, just fill in the shipping info and Seeed will handle the rest. Designer could also purchase other product or services for future work. To compensate the process, 10% of all purchases will be returned to designer’s next month balance.
- Balance could be withdrawn once each month to instructed bank account or Bazaar account credit.
Seeed Studio will cover shipping loss.
Wholesale order
Designer with their own distributor network could use bazaar as a logistics center. We integrate this in Designer purchase for easier handling and leave maximal flexibility to Designers. The purchase of their own product will be circled back to themselves deducting handling fees. The 10% compensation is supposed to counteract handling fee impact to wholesale pricing.
For each revision, Seeed view it as an individual projects. Each Designer will have a grand balance of all owned projects. After initial deposit is made, future projects could use positive balance.
