Common Mistakes When Bidding for Public Contracts in the Dominican Republic

Public procurement can provide significant business opportunities for companies that supply goods, services or public works in the Dominican Republic. But government tenders are not ordinary commercial sales processes. The supplier must demonstrate that its offer complies with requirements established in advance, submit the required information through the applicable system and meet the procedural deadlines.

The current framework is based on Law No. 47-25 on Public Procurement, which entered into force on January 28, 2026, together with Regulation No. 52-26. The Dirección General de Contrataciones Públicas (DGCP) is the central public procurement authority, while the Electronic Public Procurement System (SECP) is the principal electronic platform for managing procurement procedures. The transition to the new framework is being implemented progressively, so suppliers should always check the rules and documents applicable to the particular procedure they intend to enter.

Why Small Mistakes Can Matter in a Public Tender

In a private commercial negotiation, a buyer may decide to overlook a missing document or ask a supplier to correct an error informally. Public procurement works differently. Contracting institutions must apply the procedure and evaluation criteria established for the procurement, and suppliers are expected to submit proposals that comply with those requirements.

Law No. 47-25 provides that submitting a proposal means the bidder accepts the applicable bidding documents, amendments and rules governing the procedure. The law also distinguishes between the technical proposal, or Sobre A, and the economic proposal, or Sobre B. The technical submission contains qualification information and the technical proposal, while the economic submission contains the proposed price or cost and, when applicable, the bid guarantee and declaration that the offer is free from collusion.

This makes preparation particularly important. A company can have the right product, sufficient experience and an attractive price but still encounter problems if it fails to satisfy a mandatory requirement or submits information in the wrong form.

1. Not Reading the Entire Bidding Document

One of the most common mistakes is treating the procurement notice as if it contained everything a supplier needs to know. The notice is only the entry point. The complete bidding documents normally contain the technical specifications, eligibility requirements, evaluation methodology, forms, delivery conditions, contractual provisions, deadlines and other instructions that determine how the proposal will be evaluated.

A supplier should therefore read the entire procurement package before deciding whether to bid. Particular attention should be paid to requirements described as mandatory, documents that must be submitted, technical specifications and the criteria used to determine the winning offer.

The distinction between qualification requirements and evaluation criteria is especially important. A company may meet the general qualifications to participate but still fail to obtain the necessary evaluation score or fail to satisfy a mandatory technical condition.

A useful internal practice is to create a compliance matrix before preparing the proposal. Each requirement can be listed alongside the document, certificate, technical response or other evidence that will demonstrate compliance. This turns a long procurement document into a practical checklist without replacing the need to read the original documents carefully.

2. Submitting Incomplete Documentation

Missing documentation is one of the clearest avoidable risks. Suppliers should not assume that a document is unnecessary simply because the institution may already have information about the company.

Law No. 47-25 contains an important qualification: documents already available in the contracting institution’s files or accessible through the interoperability systems enabled by the governing authority should not automatically become grounds for disqualification merely because the supplier did not submit them in the technical proposal. Nevertheless, this does not mean that companies can ignore documentary requirements. The specific procurement documents and the information available through official systems remain decisive.

Businesses should verify the status of corporate, tax, technical, financial and other documents before submitting an offer. They should also check whether certificates have expired, whether legal representatives have the required authority and whether documents must follow a particular format.

The DGCP has previously identified suppliers with expired legal documentation as a recurring source of alerts in the procurement system. Under the current framework, suppliers should therefore maintain their registration and supporting information continuously rather than waiting until a tender appears.

3. Assuming Every Missing Document Can Be Fixed Later

Another dangerous assumption is that a supplier can submit an incomplete proposal and correct everything after the deadline. Public procurement rules can permit clarification or correction of certain deficiencies, but this does not create a general right to rewrite an offer after submission.

The distinction is between a formal or non-substantive deficiency and a deficiency that changes the substance of the proposal. A correction should not transform a proposal that failed to meet a substantive requirement into one that qualifies after the deadline.

Suppliers should therefore prepare their proposals on the assumption that every important requirement must be satisfied before submission. If the procurement documents provide a specific opportunity for clarification or correction, that mechanism should be treated as a limited procedural safeguard rather than as an extension of the bidding period.

4. Misunderstanding the Technical Specifications

Technical non-compliance can be more damaging than an uncompetitive price. A supplier may offer a product that appears similar to what the government needs but differs in a technical characteristic that the procurement documents expressly require.

Companies should compare their proposed goods, services or works line by line with the technical specifications. Dimensions, capacities, materials, performance standards, certifications, delivery conditions and other measurable characteristics should be verified rather than assumed.

When a specification is unclear, the appropriate response is to use the clarification mechanism provided by the procurement procedure. A supplier should not simply interpret an ambiguous requirement in the way most favorable to its own product and hope the evaluator will reach the same conclusion.

The same principle applies to services and works. A company should demonstrate how its proposed methodology, personnel, equipment and experience correspond to the stated requirements instead of relying on general claims about its capabilities.

5. Failing to Check the Evaluation Criteria

Some companies spend most of their preparation time on the product and price while paying insufficient attention to how the proposals will actually be evaluated. This can result in a technically good offer that does not perform well under the published methodology.

The procurement documents should make clear what the contracting institution will evaluate and how the criteria will be applied. Depending on the procedure, the assessment can involve technical compliance, qualifications, experience, price, quality, life-cycle costs or other factors established in advance.

The supplier should build its proposal around those criteria. If experience is evaluated, the relevant experience should be documented clearly. If a technical methodology receives points, that methodology should address the criteria directly. If price has significant weight, the economic proposal should be prepared with a precise understanding of what costs must be included.

There is little value in producing an impressive proposal that spends pages discussing issues that have no relevance to the published evaluation methodology.

6. Making Errors in the Economic Offer

Economic offers deserve a separate quality-control process. A mistake in a unit price, quantity, total, tax treatment or calculation can affect the competitiveness or validity of a proposal depending on the applicable rules.

Under Law No. 47-25, the economic offer contains the proposed price or cost and, when applicable, the guarantee of seriousness of the offer and a declaration that the offer is free of collusion. Suppliers should verify that the economic submission contains every element required by the procurement documents.

Before submission, the company should reconcile the economic proposal with the technical proposal. Quantities, units of measurement, delivery schedules and product descriptions should match. The final price should also reflect the supplier’s actual cost of fulfilling the contract, including logistics, personnel, financing, guarantees and other obligations where applicable.

A low price is not necessarily a successful strategy if the supplier has underestimated the cost of performance. Public contracts create real delivery and performance obligations, so the commercial team should confirm the assumptions behind the price before the proposal is submitted.

7. Using the Wrong Price or Cost Basis

Another economic mistake is failing to understand exactly what the contracting institution is asking the supplier to price. Some procurements involve multiple items, stages or services, while others may require consideration of costs over the life cycle of the good, service or work.

The supplier should determine whether the requested figure is a unit price, total price, periodic amount, project price or another specified measure. If the bidding documents establish a particular pricing form, that form should be followed precisely.

When life-cycle costs are relevant, the supplier should not evaluate the opportunity solely by looking at the initial purchase price. The applicable methodology may take into account costs associated with operation, maintenance or other elements over the relevant period.

8. Forgetting the Bid Guarantee When It Applies

Some procedures require a guarantee of the seriousness of the offer. Where it applies, the supplier should verify the required amount, validity period, form and issuing conditions before submitting the economic proposal.

This is an area where a last-minute approach can create unnecessary risk. A company should not wait until the final hours before the deadline to request a guarantee if the financial institution or other issuer needs time to prepare it.

The safest approach is to identify the guarantee requirement as soon as the tender is selected for internal review and confirm that the proposed instrument meets the exact conditions of the procurement documents.

9. Missing a Deadline

A technically excellent proposal can be useless if it is submitted after the applicable deadline. Public procurement calendars are procedural requirements, not informal targets.

Suppliers should record every important date when they decide to participate. This includes the deadline for questions, technical meetings where applicable, submission of proposals, publication of amendments, correction periods and any other date established by the procurement documents.

Companies should also avoid planning to submit at the last possible minute. Electronic systems can create practical problems, and resolving an account, document or upload issue immediately before a deadline can be difficult.

A better practice is to establish an internal submission deadline earlier than the official one. This gives the company time to conduct a final review and address technical problems without depending on an extension that may never be granted.

10. Failing to Monitor Amendments and Clarifications

Reading the original bidding documents is not enough. A procurement can generate questions, answers, clarifications and amendments that become part of the information bidders must consider.

Law No. 47-25 recognizes mechanisms for observations, clarifications and amendments during the pre-contractual stage. For suppliers, this means that the procurement should be monitored throughout the period between publication and submission rather than treated as a static document.

An amendment can affect a technical requirement, deadline, form, quantity or other important element. A company that prepares its proposal using an outdated version can therefore create an avoidable compliance problem.

The person responsible for the bid should have a defined process for checking the SECP and incorporating any official changes into the working proposal.

11. Preparing the Bid Without a Final Compliance Review

Companies often divide a tender between commercial, technical, legal and financial teams. This can improve the proposal, but it can also create inconsistencies if nobody performs a final review of the complete submission.

The final review should verify that the proposal tells one consistent story. The company name, legal information, product descriptions, quantities, experience records, technical specifications and prices should agree throughout the submission.

A final reviewer should also compare the completed proposal against the original procurement checklist rather than merely proofreading the text. The question should be: Have we demonstrated compliance with every applicable requirement?

12. Treating Company Registration as an Afterthought

Businesses should resolve their supplier-registration status before they begin preparing a serious bid. For Dominican companies, this includes maintaining the relevant information associated with the Registro de Proveedores del Estado (RPE) and ensuring that the company’s registered activities correspond appropriately to the goods or services it intends to offer.

Foreign companies can participate under the mechanisms established for international suppliers. The DGCP states that foreign individuals and legal entities can receive provisional registration in the SECP for participation and must complete the applicable definitive registration requirements if they are awarded a contract.

Foreign suppliers should also consider document formalities early. Corporate documents issued abroad may require translation, apostille or legalization depending on the document and applicable requirements. Waiting until the end of a procurement can make an otherwise manageable requirement unnecessarily difficult.

13. Ignoring Conflicts of Interest and Integrity Requirements

Public procurement is not only a competition over price and technical quality. Integrity requirements are fundamental to the system. Suppliers should ensure that their participation is independent, that submitted information is authentic and that employees or representatives understand the restrictions applicable to the procedure.

Law No. 47-25 requires an offer-free-of-collusion declaration as part of the economic proposal when applicable under the procedure. The declaration is intended to confirm that the offer is genuine, made in good faith and free of collusive conduct.

Companies should therefore avoid informal arrangements with competitors concerning prices, market allocation, bid rotation or other conduct that could undermine competition. They should also take particular care when preparing information about ownership, relationships or representatives where the procurement documents require disclosure.

14. Submitting Inaccurate or Altered Documents

Document authenticity should never be treated as a minor administrative matter. A supplier should verify every certificate, experience record, financial document and other piece of evidence before submitting it.

The DGCP has publicly reported procurement investigations involving altered or apparently false documentation, as well as cases in which suppliers faced proceedings after allegedly presenting false documents. Such conduct can go far beyond losing an individual tender and can expose a supplier to administrative consequences.

The safest policy is simple: if a document cannot be verified, the company should not submit it as evidence. If an experience certificate or other record contains an error, the supplier should resolve the issue with the issuing entity rather than modifying the document itself.

15. Assuming the Lowest Price Will Always Win

Price is important, but the assumption that the lowest price automatically wins can lead companies to prepare the wrong type of proposal. The applicable evaluation methodology determines how the institution selects the successful offer.

Depending on the procedure, the evaluation can incorporate technical qualifications, quality, life-cycle costs and other criteria in addition to price. Suppliers should therefore understand the weighting and methodology before deciding how to position their proposal.

Where price is heavily weighted, the company must remain commercially competitive. Where quality or technical criteria have greater importance, simply reducing the price may not compensate for a weak technical proposal.

16. Failing to Verify Whether the Company Can Actually Perform the Contract

A tender should not be approached as an opportunity to win first and solve the operational details later. Before submitting an offer, management should confirm that the company has the capacity to meet the contractual obligations if selected.

This may include production capacity, inventory, personnel, specialized equipment, financing, insurance, transportation, import arrangements and the ability to meet the required delivery schedule. For public works and complex services, the assessment may also involve project management capacity and the availability of qualified personnel.

An aggressive bid that cannot be delivered can create a much greater problem than losing the tender. Suppliers should therefore calculate the operational requirements before finalizing the economic proposal.

17. Starting Performance Before the Contract Is Properly Formalized

An award notification should not automatically be treated as permission to begin performing the contract. The supplier should confirm that the required formalization, guarantees and other conditions have been completed.

Law No. 47-25 establishes rules for formalizing contracts following an award. The exact steps can differ according to the procedure and type of procurement, but the general principle is important: suppliers should know when the legal relationship has moved from award to formal contractual execution.

Starting work prematurely can create uncertainty about payment, responsibility, acceptance and other contractual matters. The supplier should therefore obtain and review the applicable formal documentation before committing substantial resources.

A Practical Pre-Submission Checklist

Before submitting a public procurement proposal, a company can use the following checklist as a final internal control. It should supplement, not replace, the official requirements of the particular procurement.

• Eligibility: Confirm that the company and proposed personnel satisfy the applicable qualification requirements.
• Registration: Verify the company’s RPE and SECP status and the accuracy of the information available to the contracting institution.
• Documents: Confirm that required legal, technical, financial and qualification documents are available and valid.
• Technical proposal: Check every requirement against the proposed goods, services or works.
• Evaluation: Confirm that the proposal addresses every published evaluation criterion.
• Economic proposal: Recalculate prices, quantities, totals and other financial information.
• Guarantee: Confirm whether a bid guarantee is required and whether the proposed instrument complies with the procurement documents.
• Integrity: Verify the required declaration concerning the authenticity and non-collusive nature of the offer.
• Amendments: Check the latest official version of the procurement documents and incorporate every applicable addendum or clarification.
• Deadline: Confirm the exact submission date and time in the applicable procurement system.
• Final review: Have a person who was not responsible for preparing the proposal conduct an independent compliance check.

How to Build a Better Internal Bidding Process

The most effective way to prevent procurement mistakes is to avoid relying on one person to remember every requirement. Companies that participate regularly can create a standardized bid-management process with defined responsibilities for legal, technical, financial and commercial review.

The process can begin with a bid/no-bid decision. Before investing substantial time, the company should determine whether it is eligible, has the necessary capacity, can meet the timetable and can price the contract sustainably.

If the company decides to proceed, it should create a requirements matrix, assign each requirement to a responsible person and establish an internal deadline before the official submission date. The final stage should be an independent compliance review that checks the completed proposal against the official procurement documents.

This approach is particularly useful for foreign companies and businesses participating in larger tenders, where documentation may come from several jurisdictions or departments. A structured process reduces the possibility that an important requirement will remain buried in a long technical document until it is too late.

What Suppliers Should Do When a Requirement Is Unclear

The safest response to an unclear requirement is not to guess. Suppliers should use the clarification mechanisms established in the procurement procedure and rely on official answers or amendments published by the contracting institution.

This is important because an interpretation that seems commercially reasonable may not match the contracting institution’s intended requirement. If the question affects the supplier’s technical design, pricing or eligibility, obtaining clarification before submitting the offer can prevent a much more serious problem later.

Suppliers should also preserve records of the questions they submit and the official answers received. These records can form part of the company’s internal bid file and help ensure that the final proposal reflects the latest information available to participants.
