Types of procedure: open, restricted, quotation, direct award, expression of interest
What each procedure means, who can respond, what it asks of you, and the thresholds that trigger it in your country.
Guinea edition: the rules shown are this country's.Change country
The procedure is how the buyer puts firms in competition. It tells you whether you can respond, what you hand in and how much time you have. The exact name changes from one country and funder to another, but the mechanisms are the same. The notice or tender file always says which one applies.
Open tender
What it is. The buyer publishes a notice, and any firm meeting the conditions can respond. This is the rule for contracts above a certain amount and the case most of this guide describes.
National or international. A national tender mainly targets firms in the country and is published there. An international tender is published more widely and assumes foreign competition. This does not shut you out: a local firm can respond if it meets the criteria, but they are often higher and the file may be in English. Conversely, a national notice can remain open to foreign firms, especially when a funder pays for it.
What you hand in. The administrative documents, the technical bid, the financial bid and the bid security if one is requested.
The trap. Thinking "open" means "within anyone's reach". The file may demand a turnover, references or equipment beyond you. Read the criteria before you start.
For a small firm. Look at the lots first, the parts of the contract the buyer puts out to competition separately. Each lot is evaluated on its own, and you can often respond to just one, with more modest requirements. If you respond to several, the file may require your capacity to cover their total. Otherwise, see Joint ventures and subcontracting.
Restricted tender and prequalification
What it is. Only firms invited by the buyer can submit a bid. "Restricted" covers two situations: either the buyer first published a prequalification notice and selected the qualified candidates, or it directly invites firms it knows, where the rules allow this.
Who can respond. At prequalification, any interested firm. After that, only those selected.
What you hand in. First a qualification file with no price: legal status, turnover, similar contracts, resources. Then, if you are selected, a full bid.
The trap. Taking prequalification lightly. If you are not on the list, you will not even see what follows. Another trap: what you declared at prequalification must still be true when you bid, and the file may ask you to confirm it.
For a small firm. Respond to prequalification notices in your sector, even if the contract looks out of reach: it is a way of becoming known. Where the procedure runs with no public notice, only your reputation with the buyer can get you invited.
Quotation and request for prices
What it is. For small amounts, the buyer asks a few suppliers for prices and chooses, most often, the cheapest compliant one. Depending on the country it is called a cotation, demande de cotation, demande de prix or demande de renseignements et de prix.
Who can respond. The firms consulted and, when a notice is published, all those meeting the conditions.
What you hand in. A light file: a signed quote, the technical sheet of the product or service and a few administrative documents. Delivery terms count as much as the price.
The trap. Time limits are short, sometimes a few days. Without up-to-date certificates you are out before you even price. A request forgotten in an inbox is as good as a refusal.
For a small firm. This is often the best way in: small amounts, few formalities and your first references. But you only receive a request if the buyer knows you. Register on supplier lists where they exist, introduce your business to the purchasing departments of buyers in your region, and keep a standard quote with current prices so you can answer fast. At international agencies the equivalent is the RFQ: see the United Nations page.
Direct award
What it is. The buyer deals directly with one firm, with little or no competition. It is called gré à gré, entente directe or marché négocié depending on the country. It is the exception, kept for defined cases: real emergency, exclusive right, a service only one supplier can provide. It most often needs an authorisation.
Who can respond. Nobody: there is nothing to respond to. You cannot apply for a direct award.
What you hand in. If the buyer approaches you, a bid and supporting documents, followed by a negotiation.
The trap. The go-between who offers to "arrange" a direct award for a commission. That is corruption: you risk debarment from public contracts and prosecution, with no guarantee of a result.
For a small firm. There are honest ways of being considered. Make your rare capacities known, such as an exclusive dealership, an approval or a presence in a hard-to-reach region. Keep a clear company page. Do small consultations well, because a buyer calls back suppliers who delivered. And a direct award given to another firm can open subcontracting for you.
Expression of interest (AMI)
What it is. The buyer publishes an expression of interest notice (avis à manifestation d'intérêt, or AMI) to identify candidates before launching its consultation. You are not bidding yet: you are showing your references to get onto a list. This is the normal route for consultants, though a buyer may also use it for works or supplies.
Who can respond. Any firm, consultancy or consultant within the scope of the notice, alone or in association if the notice allows it.
What you hand in. A letter, a company presentation and above all similar assignments described and proved: client, subject, period, amount, your role. No price, and generally no methodology yet. The notice says whether CVs are requested.
How the shortlist works. The buyer scores the experience against the notice's criteria and keeps the best placed, in limited number. Only they receive the request for proposals, where the methodology, experts and price come in. This is described in Works, supplies, services, consulting.
The trap. Sending a general brochure. The reader is looking for assignments that resemble this one. Present the closest first and use the notice's words. Do not attach a price.
For a small firm. If your references fall short, associate with a firm that has the missing ones. Do it at the expression of interest stage, because changing the team afterwards is often restricted.
Two-stage tender
What it is. For a complex purchase the buyer cannot yet fully specify, it first asks for technical proposals with no price, discusses them with candidates and refines its need. It then asks for final bids with prices.
Who can respond. Firms admitted to the first stage, to which the notice generally invites them.
What you hand in. A technical proposal with no price, then a revised technical bid and a financial bid.
The trap. Confusing this with two envelopes. Two envelopes means a technical and a financial bid handed in on the same day and opened separately. Here, there are two submissions at different times. Another trap: stating a price at the first stage.
For a small firm. The procedure is long and costly, and rarely within your reach alone. Access comes rather through a partnership with a large bidder, as a specialist or subcontractor.
Framework agreement and call-off contract
What it is. The buyer selects one or several suppliers for a set period, with prices or terms fixed in advance, then orders as needed. Names vary: accord-cadre, marché à commandes, marché de clientèle, or long-term agreement at international bodies.
Who can respond. It depends on the starting procedure, most often a tender. If there are several holders, they are sometimes put back in competition for each order.
What you hand in. A standard bid, with unit prices that bind you for the whole period.
The trap. Reading the maximum amount as guaranteed turnover. The buyer can order far less, and the file sometimes sets a minimum, sometimes none. Also check whether your prices can be revised: a frozen price and a rising cost is paid for over the whole period.
For a small firm. Regular orders are valuable, but they require stock, cash and the ability to deliver quickly on each order. Work out what you can sustain at the highest volume.
In your country
Here are your country's procedures, under their local names, with the cases where each is used.
Open tender (national or international), with or without prequalification
This is the rule: any non-excluded firm may bid (art. 21 and 23). Above the award thresholds the contract must be awarded under the Code. For large, complex or technical works or equipment, prequalification may precede the tender (art. 24). A tender is valid only if the buyer receives at least 3 bids, of which 2 are admissible (art. 22).[2][1]
Minimum period: At least 30 calendar days from publication of the notice for a national tender, 45 days for an international tender (art. 55). In simple urgency authorised in advance by the finance minister, publicity may be shortened by 7 working days (art. 21). If fewer than 3 bids arrive, the buyer opens a new period of at least 15 calendar days and may then open even a single bid (art. 22 and 74).[2]
For you: Since May 2026, many contracts that would have gone to tender now go through a request for quotation. Open tenders now cover large contracts: if you target State contracts of several hundred million GNF, watch quotations as well.
Restricted tender
Only candidates the buyer consults submit a bid. The goods, works or services must, by their specialised nature, be available from a limited number of providers or, for certain goods, be locally produced or crafted. The buyer must seek authorisation from the finance minister after the control body's opinion. The list has at least 5 candidates (3 at minimum by exception), and the decision is published. Without authorisation the restricted tender is void (art. 28).[2]
Minimum period: Same period as an open tender (art. 28 referring to art. 55), from the sending of the invitation letter or the deadline for collecting the dossier.[2]
For you: The Code allows a non-invited candidate to express interest, based on the notice published at the start of the year on planned restricted tenders. Read that annual notice and write to the buyer.
Request for quotation
Below the award thresholds, the buyer may use formal requests for quotation sent by the PRMP to at least 3 qualified providers, with the specifications and performance terms (Code, art. 21). The 2026 order makes it compulsory for any spending of 50 million GNF or more. Below 50 million, purchases are made on comparative invoices.[2][1]
For you: This is small firms' way in. Providers are chosen by the buyer: keep a current file (commercial register, tax clearance, references) and introduce yourself to the procurement officers of the authorities you target. General procurement notices, which include requests for quotation (art. 20), give the calendar.
Direct agreement (single-source)
Cases set by the 2012 law: exclusive right or patent held by one provider; defence and security secrecy; extreme urgency to replace a defaulting contractor; compelling urgency from unforeseeable events or force majeure. Prior authorisation by the finance minister after the control body's opinion, otherwise the contract is void. Competition among at least 3 candidates remains in principle mandatory. The yearly total of direct-agreement contracts of each authority must not exceed 10% of its contracts (Code, art. 38 and 39).[3][2]
For you: A direct agreement without authorisation is void: before signing, ask for the finance minister's authorisation reference. The contractor accepts price control during performance (art. 41).
Expression of interest and shortlist (intellectual services)
For studies, supervision and assistance: the buyer publishes an expression of interest notice, draws up a shortlist of 6 to 8 preselected candidates (at least two national consultants if they meet the criteria), then sends a request for proposals. The proposal sits in a single envelope containing the technical and financial offers, each sealed (art. 33).[2]
Minimum period: 15 days from publication of the notice for expressions of interest; proposals follow the periods of article 55 (art. 33.2).[2]
For you: With a shortlist of 6 to 8 names, the expression of interest file is the real selection. A Guinean firm has a good chance of getting in, since the Code requires at least two qualified national consultants.
Two-stage tender
For highly complex contracts or those awarded on performance criteria. Bidders first submit technical proposals without prices, then final priced offers on a revised dossier. A reasoned request, finance minister authorisation and the control body's opinion are required (art. 26 and 27).[2]
For you: You may withdraw before the final stage without losing your bid guarantee (art. 27).
Framework agreement
For repeat orders or purchases pooled by several authorities. Prior authorisation by the control body. If there are several holders, there are at least three, if the number of bids allows. The agreement is performed through purchase orders or follow-on contracts (art. 47).[2]
For you: Being selected does not guarantee orders: read the minimums and maximums in value or quantity.
The choice of procedure often depends on the estimated amount. The thresholds below set it when the national code applies. A funder or international body has its own.
| Buyer | Contract | Amount | Effect |
|---|---|---|---|
| State | Works | 2,000,000,000 GNF (single threshold, tax included) | From this amount the spending must be awarded under the Code (tender).[1] |
| Decentralised services (regions, prefectures) and communes | Works | 1,500,000,000 GNF | Tender threshold for these buyers' works.[1] |
| State | Supplies | 1,500,000,000 GNF | Tender threshold for supplies.[1] |
| State | Services | 1,500,000,000 GNF (ordinary services) | Ordinary services follow the supplies threshold.[1] |
| Decentralised services (regions, prefectures) and communes | Supplies | 1,000,000,000 GNF | Tender threshold for supplies.[1] |
| Decentralised services (regions, prefectures) and communes | Services | 1,000,000,000 GNF (ordinary services) | Ordinary services follow the supplies threshold.[1] |
| State, decentralised services and communes | Consulting | 1,000,000,000 GNF (intellectual services) | Single threshold for all three levels. Below it a request for quotation is possible.[1] |
| Public companies and administrative public establishments | All | Amount not restated in the 2026 order: refers to articles 18 and 28 of law L/2017/056/AN | The applicable threshold is the one in the law on financial governance of public companies and establishments.[1] |
| All buyers, below the thresholds above | All | 50,000,000 GNF or more | Request for quotation compulsory, sent to at least 3 qualified providers. Below 50 million: comparative invoices.[1][2] |
| Tenders: national publication (legal-notice newspapers) | All | Up to 20 billion GNF (works) and 15 billion GNF (supplies, ordinary services, intellectual services) | Notices for these contracts are published nationally. Regional-only publication is enough up to 2 billion GNF (works) and 1.5 billion GNF (others). It must not exclude foreign firms.[1] |
| Approval: sector ministers | All | Up to 2 billion GNF (works); 1.5 billion GNF (supplies, ordinary services, intellectual services) | Above this the finance minister approves. Governors and prefects: up to 1.5 billion (works) and 1 billion (others). Mayors: all contracts on own funds in their district.[1] |
| Approval, external financing | All | US$1,000,000 (sector ministers); US$500,000 (project and programme coordinators) | Approval ceilings for contracts financed by funders.[1] |
A buyer may not cut a need into small purchases to stay under a threshold and avoid a stricter procedure: this is called splitting (fractionnement). Do not confuse it with lots, which are legitimate and published in a single notice. If the splitting rule seems to be bypassed on a contract, see Challenge a decision.
What next
The procedure says how the buyer sets up the competition, and the type of contract says what you must prove: see Works, supplies, services, consulting.
