About System Plus
The reverse costing analysis is conducted in several phases:
Reverse Costing Methodology
• The initialization of the analysis
Pictures of the elements to be studied.
Identification of the components.
• Description of the material in the “SYScost+” software
Creation of an “estimation project” of the studied board with SYScost+ software.
Construction of the Bill of Material (BOM).
• Assessing the material
Searching for the price of each reference among distributors and manufacturers.
Assessing the cost of the PCB and of the unaccounted references (unknown by distributors)
The BOM is valued with SYScost+ : price simulation according to the requested quantities.
• Assessing the assembling and test phases
Assembly and test lines are modeled with the SYScost+ software.
The assembly and tests costs are estimated.
• Production cost & selling price
Estimation of the production cost & selling price.
• Report
A report is edited.
SYS.cost+©, is a software tool developed by SYSTEM PLUS CONSULTING to calculate the cost of electronic boards. More information on the
software can be found at www.systemplus.fr.

PCBs Cost
The cost of the Printed Circuit Boards (PCB) has been estimated through our PCB costing model.
The cost varies according to the used technology as well as the size of the board and of the panels on which the boards will be laid-out.
Thailand manufacturing costs have been used for these calculations.

22. 1.INTRODUCTION
The present terms and conditions apply to the offers, sales and deliveries of services managed by System Plus
Consulting except in the case of a particular written agreement.
Buyer must note that placing an order means an agreement without any restriction with these terms and conditions.
2.PRICES
Prices of the purchased services are those which are in force on the date the order is placed. Prices are in Euros and
worked out without taxes. Consequently, the taxes and possible added costs agreed when the order is placed will be
charged on these initial prices.
System Plus Consulting may change its prices whenever the company thinks it necessary. However, the company
commits itself in invoicing at the prices in force on the date the order is placed.
3.REBATES and DISCOUNTS
The quoted prices already include the rebates and discounts that System Plus Consulting could have granted according
to the number of orders placed by the Buyer, or other specific conditions. No discount is granted in case of early
payment.
4.TERMS OF PAYMENT
System Plus Consulting delivered services are to be paid within 30 days end of month by bank transfer except in the
case of a particular written agreement.
If the payment does not reach System Plus Consulting on the deadline, the Buyer has to pay System Plus Consulting a
penalty for late payment the amount of which is three times the legal interest rate. The legal interest rate is the
current one on the delivery date. This penalty is worked out on the unpaid invoice amount, starting from the invoice
deadline. This penalty is sent without previous notice.
When payment terms are over 30 days end of month, the Buyer has to pay a deposit which amount is 10% of the
total invoice amount when placing his order.
5. OWNERSHIP
System Plus Consulting remains sole owner of the delivered services until total payment of the invoice.

cancel the order.
7.ENTRUSTED GOODS SHIPMENT
The transport costs and risks are fully born by the Buyer. Should the customer wish to ensure the goods against lost or
damage on the base of their real value, he must imperatively point it out to System Plus Consulting when the
shipment takes place. Without any specific requirement, insurance terms for the return of goods will be the carrier
current ones (reimbursement based on good weight instead of the real value).
8.FORCE MAJEURE
System Plus Consulting responsibility will not be involved in non execution or late delivery of one of its duties
described in the current terms and conditions if these are the result of a force majeure case. Therefore, the force
majeure includes all external event unpredictable and irresistible as defined by the article 1148 of the French Code
Civil?
9.CONFIDENTIALITY
As a rule, all information handed by customers to system Plus Consulting are considered as strictly confidential.
A non-disclosure agreement can be signed on demand.
10.RESPONSABILITY LIMITATION
The Buyer is responsible for the use and interpretations he makes of the reports delivered by System Plus Consulting.
Consequently, System Plus Consulting responsibility can in no case be called into question for any direct or indirect
damage, financial or otherwise, that may result from the use of the results of our analysis or results obtained using
one of our costing tools.
11.APPLICABLE LAW
Any dispute that may arise about the interpretation or execution of the current terms and conditions shall be resolved
applying the French law.
It the dispute cannot be settled out-of-court, the competent Court will be the Tribunal de Commerce de Nantes.
