Have you been unsuccessful in bidding on Nara Marketplace, even when offering the same amount? The reason is simple. It was because your proposal wasn't convincing.

Bidding in Nara Marketplace isn’t a simple price competition. Even with the same bid amount, some companies are selected while others are not.

The factor that differentiates is the quality of the proposal.
A proposal that meticulously analyzes the Request for Proposal (RFP) and is crafted with a persuasive flow in line with evaluation criteria can make similar content appear distinctive.

This article outlines how to effectively write a Nara Marketplace proposal in 7 steps, based on actual failed bid factors.
At the end, we also introduce practical tips on using AI to automatically complete proposals, so be sure to read through to the end.

  1. Writing a proposal without analyzing the RFP greatly increases the risk of failure

The key to successful bidding lies not only in the ‘method of bidding’ but also in how persuasively you document that method.

The most common factor for failure in Nara Marketplace proposals is the lack of analysis of the Request for Proposal (RFP).

The RFP contains detailed insights into the problems the client wants to solve, their crucial evaluation criteria, and detailed technical requirements and constraints.

However, many professionals skim through this document and start by copying and pasting from previous proposals.

Doing so results in a proposal that is entirely detached from the project’s purpose.



Three-step RFP analysis method for effective use in Nara Marketplace proposals

  1. Business Overview Analysis

    Using the background of the project, its objectives, duration, and budget, find the answer to ‘Why is this project necessary?’


  2. Proposal Writing Guide Analysis

    If you miss out on formal requirements such as participation eligibility, submission volume, schedule, and presentation requirements, you risk disqualification.


  3. Requirements Analysis

    For a proper proposal, read through technical specifications, performance, screen UI, as well as expectations, security requirements, and operating conditions.

  1. Reflect the Nara Marketplace proposal evaluation criteria in your structure

In bidding, the proposal score is mostly graded according to the evaluation sheet's itemized scoring criteria.
However, surprisingly many companies do not reflect this scoring, even after reading it.

For example, if the total score for technical competence is 90, and 70 of that is qualitative evaluation, what the judges focus on is the quality of the qualitative evaluation section.

Yet in practice, many spend 5 pages on a 10-point item and 1 page on a 30-point item.


Proposal structuring strategy based on Nara Marketplace evaluation criteria

  • Structure the table of contents starting with the items with higher scores and allocate content volume for each item in proportion to its score.

  • Differentiate key points by highlighting them visually or positioning them as advantages over competitors.

  • Since judges award scores in order of evaluation criteria, the structure flow should match that order.



  1. The core is 'differentiation strategy'

Why did we fail when our proposal seemed almost identical to those of other competitors?

The answer is a differentiation strategy. Clients want a company that understands their issues accurately and can articulate them in their own language.


Five differentiation strategies to increase bid success rate

1️⃣ Emphasize Business Understanding

  • Analyze and propose based on the client's background, objectives, and current situation.

  • Example: "The ultimate solution to this project's problem is assessed to be ○○."


2️⃣ Problem-Solution Centered Proposal

  • Offer solutions focused on the problem, not just general solutions.


3️⃣ Highlight Your Strengths

  • Show why only your company can deliver. Specify unique project experience, technical originality, and operational know-how.

  • Example: While others propose △△, we apply ◇◇-based methodologies.


4️⃣ Persuade with Quantitative Figures

  • These figures are not just reports of achievements, but evidence that the solution works in real settings. They support scoring well in proposal evaluation items like ‘Technical Feasibility’ and ‘Similar Project Performance’.

  • Example: After applying the system, we achieved over a 45% efficiency improvement. / We possess ○ records of successful similar project completion.


5️⃣ Performance-Centric Scenario Presentation

  • Clearly stating the 'post-award execution plan' in your bid proposal showcases your ability to actually carry out the project.

  • Visualizing expected results and effects post-implementation in tables or graphs allows judges to quickly grasp and trust the content.

  1. Just one formatting error can lead to disqualification

Instances of disqualification due to non-compliance with formatting requirements in Nara Marketplace bidding are not uncommon.

In the 2025 'Seoul A Public Agency Driver Dispatch Service' announcement, out of 58 participants, 24 were automatically disqualified for incomplete documents, reducing the final competition ratio to 34:1.

Such cases highlight the importance of ‘document completeness’ as a key strategy in bidding.


Nara Marketplace Bid Proposal Formatting Checklist (2025)

☑️ No more than 30 A4 pages, comply with margin and font regulations

☑️ Insert page numbers at the bottom center

☑️ Attach an abbreviation list separately when using abbreviations

☑️ Submit supporting documents in an ‘Appendix’ format

☑️ Pre-verify file names and formats when submitting electronic files

Ensure your proposal meets all these Nara Marketplace format criteria. Check this checklist before submission.

  1. 2025 Next-Generation Nara Marketplace System: Check the Changes

The Next-Generation Nara Marketplace was launched pilot-wise starting January 2025.
The separately operated e-Procurement System Service is being integrated into the Next-Generation Nara Marketplace.

The changes in the Next-Generation Nara Marketplace system are significant.
In the initial system phase, there were as many as 32,000 complaints, and even now, many practitioners face confusion due to certification errors, contract creation errors, and missing previous records.

Review the system changes before submitting your proposal.


Key Summary of Changes in the Next-Generation Nara Marketplace System

  1. Overhaul of joint certification system: The previous certification is being abolished, and pre-registration is required.

  2. Automation of contract drafting: The method of creation has changed, so familiarize yourself with the new UI.

  3. Errors in record transfer: It is stable to manually verify past bid history.



  1. Bid Success Rate Hinges on Data Analysis

Merely participating in all bids does not boost winning probabilities. Random participation only accumulates risk without increasing records. ‘Quality over quantity’—target only potential successful bids and prepare meticulously for a worthwhile attempt.

Analyze the bid results in announcements to understand Nara Marketplace competition rates and bid ratios.
