İhaleYapı

Corporate E-Procurement and Tender Platform

İhaleYapı lets businesses that buy regularly, construction and building firms first among them, run their tenders and quotation requests on one platform. Every company works in its own closed space, suppliers bid from their own portal, and the purchasing team reviews bids line by line with notes and target prices, reaching the best price through negotiation rounds.

We Understand the Problem, We Build the Solution

The Problem

  • Most purchasing teams still collect quotes by email, phone and Excel. Supplier prices arrive in different formats, comparing them line by line takes hours, and which revision was asked of which supplier gets lost in the correspondence.
  • Because negotiation is not recorded, transparency is weak: who offered what in which round, or which line got a target price, cannot be traced later. That raises both cost and audit and compliance risk.

İhaleYapı Solution

  • İhaleYapı digitises purchasing from start to finish. Your company sets up its own closed space on the platform, opens a tender or a request for quotation, builds the lines in minutes from catalogue products and services, and invites its suppliers. Suppliers enter unit prices and track their progress from their own portal.
  • Incoming bids are compared line by line on one screen. The purchasing team adds a note or a target price to each line and splits negotiation into rounds; every round, bid and decision stays on record. The result: lower cost, faster decisions and an auditable, transparent purchasing process.

Key Features

  • Multi-Tenant Closed Spaces

    Each company works in its own isolated environment; tenders, bids and supplier data are never shared with another company.

  • Tenders and Quotation Requests

    Open full tenders or quick requests for quotation; delivery date, lines and terms are defined in one flow.

  • Supplier Portal

    Invited suppliers bid from their own panel, update unit prices and follow their progress; the email back-and-forth ends.

  • Line-by-Line Evaluation

    Bids are compared line by line on one screen; each line can carry a note or a target price.

  • Negotiation in Rounds

    Negotiation is split into rounds; bids and feedback in every round stay on record, and the process is transparent end to end.

Frequently Asked Questions

Does İhaleYapı track public tenders?

No. İhaleYapı is an e-procurement platform built for your company's own purchasing tenders and quotation requests: you open the tender, you invite your suppliers and you evaluate the bids in the system.

Do suppliers need an account too?

Suppliers join their dedicated supplier portal by invitation. There they see only the tenders they are invited to, submit bids and follow their progress.

How is our data kept apart from other companies?

The platform is multi-tenant. Each company's data is isolated by tenant filters in authentication and the data layer; one company's tenders and bids cannot be viewed by another.
