Tryb podstawowy — Poland's sub-threshold basic procedure
Tryb podstawowy is the procedure Polish contracting authorities use for contracts below the EU thresholds. It is not one procedure but three: art. 275 gives the buyer a choice between awarding without negotiation, reserving an option to negotiate, and negotiating as a matter of course. Which variant applies changes whether your first price is your final price, so it is the first thing to read in the notice.
What it is
For contracts at or above the EU thresholds, art. 129 of Prawo zamówień publicznych offers seven named procedures familiar from the EU directives. Below those thresholds — that is, from 170 000 zł upwards since 1 January 2026 — Polish buyers use tryb podstawowy, the basic procedure, under art. 275.
Art. 276 ust. 1 provides that the buyer commences the procedure by publishing a contract notice in the Biuletyn Zamówień Publicznych. Art. 276 ust. 2 lets it additionally notify known contractors active in the relevant field directly, after the Bulletin publication.
The three variants
Art. 275 states that in the basic procedure, in response to a contract notice, all interested contractors may submit offers, and the buyer then:
1. selects the most advantageous offer without conducting negotiations — pkt 1;
2. may conduct negotiations to improve the content of offers, and after they conclude invites contractors to submit additional offers — pkt 2;
3. conducts negotiations to improve the content of offers, and after they conclude invites contractors to submit final offers — pkt 3.
The grammatical difference between może prowadzić in pkt 2 and prowadzi in pkt 3 is the whole distinction. In the second variant negotiations are an option the buyer reserves and may never exercise; in the third they are part of the design.
The documents differ too. Art. 280 requires free, full, direct and unrestricted access on the proceeding's website, from the day of Bulletin publication, to the SWZ in the pkt 1 and pkt 2 cases, and to an opis potrzeb i wymagań — a description of needs and requirements — in the pkt 3 case. So in the third variant there is no full specification at the outset; the detailed terms emerge through negotiation.
Art. 279 constrains those negotiations in the pkt 3 case: they may not lead to a change in the minimum requirements concerning the subject matter or its performance as set out in the description of needs and requirements, and they may concern the terms of the contract in order to increase its effectiveness.
Art. 288 lets the buyer limit how many contractors it invites to negotiations in the pkt 3 case, provided the number is sufficient to ensure competition and not fewer than three, and provided the criteria it will apply and the maximum number are stated in the notice and in the procurement documents.
Art. 293 closes both negotiated variants: in the pkt 2 case the buyer simultaneously informs all contractors whose offers were not rejected that negotiations have ended and invites additional offers; in the pkt 3 case it informs all such contractors who took part in negotiations and invites final offers.
Why there is no clean English term
Translations you will see include basic mode, basic procedure and basic tender. None of them is a term of art, and none maps onto an EU procedure, for a straightforward reason: the directives do not govern contracts below the EU thresholds, so there is no directive procedure for this to be a translation of.
It is also not a single procedure that can be equated with an open procedure or a competitive procedure with negotiation. It is one national procedure with three configurations, and the buyer picks the configuration when it launches. Art. 281 ust. 1 requires the specification to state, among its mandatory items, information about whether the buyer intends to select the most advantageous offer with or without negotiations. Treat that item as the single most informative line in the document.
The timetable
Art. 283 sets minimum periods for submitting offers: not less than 7 days from publication in the Bulletin for supplies and services, and not less than 14 days for works. Buyers routinely use the minimum.
Art. 284 governs questions. A request for clarification of the specification or of the description of needs and requirements obliges the buyer to answer only if it arrives at least 4 days before the submission deadline; the buyer must answer promptly and no later than 2 days before the deadline. If it misses that, it must extend the deadline by the time needed for all interested contractors to absorb the clarification.
Within a seven-day window, four days before the deadline is day three. Questions must be drafted almost immediately.
What to do about it
Read the notice and the specification for the variant before you do anything else.
Under pkt 1, the offer you file is the only offer you get. Price it as final; there is no second round.
Under pkt 2, negotiations may or may not happen, and if they do you will be asked for an additional offer. Do not assume there will be a chance to improve — the buyer is not obliged to take one.
Under pkt 3, expect negotiation. There is no full specification at the start, only the description of needs and requirements; the minimum requirements in it are fixed, but the terms of the contract are genuinely in play. Check whether the buyer has limited the number invited to negotiations, and on what criteria, because that shortlisting step decides whether you reach the table at all.
In all three, plan for a seven- or fourteen-day window and a four-day question deadline.
