Responding to the market: preparing the bid dossier
Verified 01 April 2026 - Entreprendre Public Service / Directorate of Legal and Administrative Information (Prime Minister)
The response to a public procurement contract shall include an application and an offer. The offer offered by the company includes a technical offer and a financial offer. It is sometimes accompanied by other documents (intervention planning, product catalog). In some cases, the candidate may present different solutions from those proposed by the buyer: we speak of “variants”.
The offer is the candidate's response to the need expressed by the public purchaser in the consultation documents.
It shall contain the following documents:
- Technical offer or technical memory : it details the technical response provided by the candidate to the buyer's needs
- Financial offer : it corresponds to the candidate's price offer
- Other documents necessary for the examination of tenders : the public purchaser may ask the applicant company to produce other documents such as samples, models or prototypes, intervention schedules, product catalog, etc. The absence of delivery of one of these documents when requested by the purchaser renders irregular supply
- Deed of Commitment: it is the essential document of the public procurement. It makes it possible to know precisely the reciprocal commitments of the successful candidate and the buyer. It can only be completed at the time of the award of the contract by the successful candidate. For more information, refer to the fact sheet sign the act of commitment in case of award of the contract
FYI
A company may choose to partner with other companies, as part of a Temporary company Grouping (GME) to respond to a larger market. It may also entrust the performance of part of the contract to other companies in the outsourcing.
Information and documents to be produced in the offer
What is a technical offer?
This is a technical brief or a methodological note that precisely responds to the specifications in the consultation documents.
The specifications set out the technical provisions necessary for the performance of the services of each contract. It provides information on the buyer's needs, delivery times, warranty conditions, maintenance, after-sales service. The applicant company must therefore respond to each point the specifications, specifying all the powers and means used.
The technical brief enables the public purchaser to assess the human, technical and logistical means available to the applicant company to perform the service.
FYI
In practice, supply for markets below €60,000 HT usually consists of the transmission of a simple quote.
What does the technical offer contain?
The applicant company has a great deal of freedom to draft its technical memorandum. It has to be built as a business case. The applicant company must indicate that it fulfills all the criteria and that it hasassets.
She must first make a general presentation to demonstrate its expertise: activity, know-how, organization, human and material resources.
She must then detail its methodology to explain how the market will be realized, controlled, delivered. This may include the following:
- Quality of the product manufacturing process (e.g. quality control procedure, skill level of the workforce)
- Technical product quality (e.g. product durability)
- Services associated with the product (e.g. quality of after-sales service, possibility of emergency response, including weekend and holidays, cybersecurity)
Public purchasers may take into account the environmental characteristics of the tender where they have a direct link with the subject matter of the contract. The applicant company can thus present a carbon balance relating to the service requested in the contract (for example, the analysis of greenhouse gas emissions linked to the production of the product requested by the buyer). It may mention the existence of a reprocessing circuit for the waste produced in the context of the contract. It may also indicate that it has certifications or labels recognized environmental. These are for example: Ecolabel, such as type 1 ecolabel, NF environment certification, organic farming label, Oeko-Tex certificate for textile products.
The applicant company may also highlight the social implications of its offer where the purchaser has provided for social criteria. These include:
- Measures to integrate groups in difficulty which may be carried out in the context of the performance of the contract.
- Training and apprenticeship efforts in the context of the contract (collaboration with a job center or a local employment agency, hiring of apprentices, vocational training actions)
- Respect for human rights in the performance of the contract (fair remuneration of producers, location of suppliers and subcontractors)
The buyer may also require capacity levels (e.g. in terms of the number of employees or professional qualifications).
Information may also be requested, such as the turnover declaration, the appropriate bank declaration or balance sheets for example.
Is there a form to respond to the public procurement?
There is no standard response framework or form to present the technical brief.
In certain cases, the public purchaser shall lay down rules for the submission of that technical brief and impose one or more of the following:
- Limiting the number of pages of the technical brief
- Proposal of a standard framework for the technical brief to be completed by the candidates
- Tabular presentation
- Prohibition of use of annexes
FYI
Where the public purchaser lays down rules for the submission of the technical brief, it must indicate them in the consultation regulation.
The technical offer must be adapted to each contract: each of the points requested in the regulation of the consultation must be answered precisely. The applicant company has an interest in customize her offer to show that she understood the buyer's need.
This offer must also be presented in a readable and clear. The layout is very important. You have to insert a summary, headings, pages between pages. Styles and fonts should also be harmonized.
The financial offer must be based on the documents provided in the consultation documents . The candidate company must fill out one of the two following documents:
- Unit Price Sheet (BPU) : it is usually structured by categories (e.g. structural, secondary, electrical, plumbing, etc.) and each category is then broken down into several sub-categories corresponding to specific elements. For each item, the BPU indicates the unit price, unit of measure, and estimated quantity. It is used in so-called “unit price” markets. This is the case, for example, with works contracts, where the buyer does not know in advance the quantities to be implemented.
- Breakdown of global and flat-rate prices (FMGF) : it is a document breaking down the elements of the flat-rate price of the service to be provided, with the quantities and elements to be quantified by the companies. In this case, the contract holder undertakes to perform a service for the proposed package, regardless of the quantities delivered or executed. The flat-rate price is not adapted to services or works whose realization presents significant technical hazards.
Please note
Care must be taken when setting the price because the buyer must reject abnormally low offers (OAB).
Market price
The Consultation Regulation (CR)of the public contract may allow the submission of ‘variants’. These are alternatives to the basic solution described in the specification.
The applicant company shall take the initiative to offer an alternative to the public purchaser's basic offer. It deals with certain technical, administrative or financial issues.
These variants make it possible to bring out innovative solutions or to use means unknown to the public purchaser.
FYI
The buyer may require the presentation of variants. It shall indicate this in the contract notice, in the invitation to confirm interest or in the consultation documents.
In contracts with an adapted procedure (Mapa), variants are permitted unless otherwise specified in the consultation documents.
In the formalized procedures, the situation depends on the public purchaser:
- When the contract is awarded by a contracting authorityHowever, variants are in principle prohibited. THEcontract notice or consultation documents may, however, authorize them.
- When the contract is passed through a procuring entityAlternatives are in principle permitted but may be prohibited by the contract notice.
Example :
Examples of technical variants:
- Materials different from those required in the basic solution
- Longevity of products or structures
- Environmental characteristics (optimization of waste management)
- Better maintenance, maintenance or warranty conditions
Presentation of variants
The period of validity of the offer is the period during which the candidate is obliged to maintain his offer. When this deadline is exceeded, the candidate is released from his commitment.
The regulations do not impose a period of validity for tenders. But the buyer can decide on such a deadline within the contract notices or consultation documents . It shall then apply to all applicants and to the purchaser, in application of the principle of equal treatment.
However, the public purchaser may, before the expiry of the period of validity of the tenders, request all candidates to extend that time limit. It must then obtain the agreement of all the candidates. If this is not the case, the proceedings are declared without further action.
FYI
In practice, the period of validity of the offer is set between 90 and 120 days.
