AI for preparing tender documents

AI-powered bidding documents help to organize the requirements of the tender, the information about the company, and the ideas for the proposal into a preliminary draft, which can then be reviewed by professionals.

“Delivery in one day” is part of the product’s positioning; it does not mean that every project can have a qualified bid document prepared within a single day.

Bid Proposal Database

The official website currently shows around 16,300 documents, including free materials, those that require separate payment, and VIP materials.

The number of databases and existing cases do not guarantee quality; it is necessary to verify the year, region, project, and applicable standards before making any references.

Library search methods

1. First, extract industry, service, and technology keywords from the project name.
2. Select the category for services, goods, projects, or learning materials.
3. Set material types such as free, paid, or VIP.
4. Compare based on the latest upload date, views, or download counts.
5. Open the document details page to view the number of pages, size, and a brief summary of the content.
6. Give priority to materials with project scopes and scoring requirements that are similar.
7. Only verifiable structures and methods are selected, without direct copying.
8. Rewrite the reference content as the actual implementation plan of our company.

Service-based solutions

• Property management, housekeeping, sanitation, cleaning, and landscaping.
• Security, catering, logistics, leasing, and maintenance.
• Consulting, assessment, training, testing, and operation.
• Labor dispatch, business outsourcing, and conference services.
• Agriculture, trusteeship, agency, cleaning, and accommodation.
• Advertising, printing, design, and software services.

Goods and project plans

Video classes and communities

Video classes are used to learn how to prepare tender documents, while the Bid Friends community serves as a platform for exchanging project experiences and addressing specific issues.

• Beginners can first learn about tables of contents, rating responses, and basic formatting.
• Business professionals should pay attention to quotes, qualifications, and supporting documents.
• Technicians can learn about implementation plans and risk control.
• Community answers should distinguish between personal experience and official regulations.
• Do not upload unredacted tender documents in public posts.
• Important conclusions should be based on the original project documents and the regulations set by the relevant authorities.

Prices of top-up packages

The pricing for the AI conversation top-up packages listed below was verified on August 31, 2026; the page displays both the current price and the original price.

The current price may be part of a promotion; the final amount, invoice, refund details, and time of payment will be indicated on the settlement page after logging in.

Comparison of single-costs

The single-cost figure is based on an average of the indicated number of times, and it does not indicate that a fixed number of words or a complete proposal can be generated per conversation.

VIP and usage rules

AI top-ups, VIP library access, and manual writing services are distinct products; purchasing one of them does not automatically entail all the services.

Reward tasks

The entry point for the task, the amount of rewards, and the rules of the campaign may change; therefore, short-term rewards should not be included in the long-term procurement budget.

Document purchase and membership boundaries

• Free documents can be viewed or downloaded according to the page rules.
• Paid documents may need to be purchased separately.
• For VIP documents, it is necessary to verify the membership period and download restrictions.
• Purchasing a document does not grant the right to resell it or distribute it publicly.
• It is necessary to distinguish between the author of the material, the person who uploads it, and the responsibilities of the platform.
• Before downloading, check the page version, number of pages, and file details.

Bid document review checklist

Risks of AI-generated content

• It is possible to fabricate company cases, personnel certificates, or technical specifications.
• It is possible to overlook the prohibitive clauses in the tender documents.
• Specifications from different regions and years may be used interchangeably.
• It’s possible to mistake historical plans for the current realities of a project.
• In long texts, there may be inconsistencies in data and terminology throughout.
• Homogenized expressions may reduce the specificity of the approach.
• Any false response may lead to the rejection of the bid or legal risks.

Confidentiality and data security

• Delete the ID number, phone number, and home address before uploading.
• Financial, quotation, and cost information should be handled in accordance with established permissions.

• Upon completion of the project, the intermediate files are archived or deleted in accordance with the established procedures.
• Classified, military, or sensitive projects should use approved environments.

Copyright and References

Historical bids and library content can help in understanding the structure, but they cannot be copied in their entirety, resold, or uploaded again without authorization.

• Confirm whether purchasing a document grants read-only rights or usage rights.
• Separate authorization is required for third-party charts, photos, and text.
• When citing standards and regulations, indicate their exact names and versions.
• Replace the template content with the actual employees and processes of your company.
• Retain records of legitimate sources, purchase history, and modification records.
• Conduct checks for duplication and infringement risks before releasing to the public.
