Two worlds of procurement. One ecosystem.
OpenNexus brings together an ecosystem where buyers and suppliers meet on equal terms. Each side has tools designed around the way they work.
For the buyer
openBuy
Conduct procedures transparently and without paper.
A platform for offices, municipalities, hospitals, and universities. Everything you need to prepare, announce, resolve, and archive a procedure—in one place, in accordance with the PZP.
All purchasing in one place
Requests for quotations, tenders, documents, and correspondence with suppliers in one environment, instead of in five tools.
Your procedures remain yours
You conduct procedures according to the PZP and your own regulations, and the platform follows what already works for you. You do not have to rewrite or change the rules.
TED in Polish
On openBuy, you publish EU notices without logging into eNotices2. You fill out the form in the language of the act.
People, not just helpdesk
We help you get started, support you throughout procurement procedures, and respond when you need a quick answer. We also offer your suppliers technical support and guidance on using the platform.
Documents are made automatically
Procurement records, calculations, and reports are generated from the data already entered in the procedure.
Signatures checked immediately
Electronic signature verification and validation take place in the system.
For the supplier
openSales
Tenders where you have a real chance.
A platform for companies starting in tenders. Less searching, fewer spreadsheets, more successful bids, thanks to an AI search engine that understands what you do.
No fees and no subscription. You create an account and use it.
All tenders in one place
National, EU, co-funded, outside the act, and private, collected together and updated daily.
A profile instead of fifty pages
Each procedure has a summary of the requirements, deadlines, and amounts drawn from its documentation. You can decide whether to bid before opening the first tender specification (SWZ) file.
AI search engine
You set what you do, and the system daily scans the market and filters out irrelevant notices. A short list remains instead of hundreds of items to click through.
Change in the procedure? You know first
You monitor selected tenders, and modifications and answers to questions arrive in your email. The full history of changes remains in the system, so you see what and when it changed.
From decision to submitted bid
A link to the right platform, a checklist of required documents, and a bid security guarantee in one place. You know where to submit your bid and what to include.
You know how it went and why
Procedure results, competitor prices, and your own bidding history in one profile. For the next tender, you enter with numbers, not with a hunch.
One ecosystem
Public procurement, where both sides benefit
Buyers need smooth procedures and strong bids. Suppliers need clear requirements and a fair chance to win. These needs complement each other. That is why we support both sides.
