Finding Requests (RFPs)

Access the platform's public RFPs and filter the right opportunities for your company.

About 5 minutes
Understand the success fee

Participation is completely free — no subscription, deposit, or fund blocking required. At the top of any RFP page, click Fee Scale to see the current fee table.

The fee is paid only by the winner, after the buyer selects them. The invoice is sent by email.
Access All Requests

Click Company Profile in the top left corner, then select Requests. You will see all public RFPs on the platform. Filter by status to find opportunities relevant to your company:

Collecting offersOpen RFPs waiting for proposals. This is where you can participate and submit your offer.
Evaluating offersThe buyer is comparing received proposals. The submission window is closed.
CompletedThe RFP is closed and a winner has already been selected.
Read the RFP details and specification

Click any RFP to view its full details: description, delivery address, tags, deadline, bid type, offer visibility, currency, tax considerations, and whether alternative offers are allowed.

Click View specification to see each item listed with technical details. If there is no specification, the buyer expects a generic offer covering the full RFP scope.

Read everything before starting: Make sure your company meets 100% of the requirements. Starting an offer you can't complete affects your profile standing.
Chapter 04

Making an Offer

Fill in your proposal with prices, taxes, and supporting documents, then submit to the buyer.

About 10 minutes
Start offer preparation

On the RFP page, click Start offer preparation. A dialog will appear — confirm your name and email, fill in your phone number, read and check the User Agreement and commission terms, then click Participate.

Participation is free. The success fee is only charged to the winner after the RFP is concluded — never at the time of participation.
Open the "Bid" tab

After joining, you'll see the RFP page with tabs at the top: Request, Bid, Comparison, Final Results. Click the Bid tab to open your offer form.

  • 1. Availability — check the checkbox for items your company can supply
  • 2. Quantity — confirm or adjust the available quantity
  • 3. Unit price without tax — set the value per unit in the RFP currency
  • 4. Tax rate — select the correct rate (17%, 20%, 22%, 25%, 30%, etc.)
Auto-calculated: Tax value, cost without taxes, and total are filled in automatically. Use the Comments column for notes per item.

Accepted formats: PDF, DOC, DOCX, RTF. Maximum: 25 MB per file.

Answer the questionnaireIf available

If the buyer has created a questionnaire for this RFP, click View criteria and answer all the questions. These responses are important for the buyer's evaluation and can differentiate your offer.

Send your offer — and consider an alternative offer

Click Send offer to submit your main proposal. If the buyer allows it, you can also send a second alternative offer with variations in price, quantity, deadlines, or payment terms — it doesn't replace your main offer and gives the buyer more options to consider.
