So the problem has two ends: finding a crew whose papers are in order, and paying it.
Suggested solution
Build an online marketplace where contractors hire building crews with checked papers, then handle their documents and pay.
- Contractor. Today: Finds crews in Facebook groups or via brokers. With the suggested solution: Gets a crew with checked papers.
- Nobody. Today: Checks the crew's papers. With the suggested solution: Checks the papers before the hire.
- The office or an outside accountant. Today: Pays the crew on general payroll software. With the suggested solution: Runs the crew's pay in the same system.
- Who does this is not known. Today: Who handles A1 papers for workers posted abroad is not known. With the suggested solution: Keeps each worker's A1 papers.
Not known: who handles A1 papers for workers posted abroad.

Sells leads to tradesmen and choice to households: a homeowner posts a job and picks on reviews. Running since 2009, it lists 33,937 registered tradesmen and firms, but the buyer is the household rather than a general contractor who needs a crew with its papers in order, and no money or document ever moves through it.

Sells the same consumer service — a household posts a job, tradesmen bid — out of Slovakia. Its Czech presence could not be verified in this pass: wilio.cz does not resolve and wilio.com is a parked domain-sales page, leaving the Slovak site as the only live one, and either way this is consumer matching rather than contractor-to-crew.

Sells construction documentation — site diary, defects, inspections, handover — from Vienna since 2013, in Czech, and states more than 200,000 users in over 75 countries. Subcontractors appear inside it once they are already on the project: it does not source them, check their documents or pay them.

Sells the payroll and HR program many Czech construction firms already run on — and sells the same program to every other industry. Nothing in it knows a site crew from an office clerk: no posted-worker A1 paperwork, no subcontractor documents, no per-site labour costing. The vendor is Seyfor, a. s., trading since 2013, with 2 public buyers on record in the state contracts register.

Sells general payroll and personnel software to businesses of every size and to the accountants who process wages for others — the second horizontal product Czech builders fall back on, and construction-blind by design. STORMWARE s.r.o. has traded since 1996, but the PAMICA pages carry no tally of who runs it and nothing else about its position could be verified.

Sells construction leads: it advertises 1,000+ checked building opportunities a month and more than 1,000 buyers posting in the previous month, and the operator, AAA poptávka, s.r.o., has traded since August 2018. The check is on the opportunity, not on the tradesman — nobody's documents are verified and no money moves through it — and the same class of portal (ePoptávka, Poptávky.cz, TrhPoptávek) sells the same thing.

Sells the crew itself: a licensed staffing agency, trading since July 2017, that recruits Ukrainian workers, employs them, runs their wages, insurance and documents, and swaps them out if the client is unhappy. That is the incumbent answer to "find a crew whose papers are in order", sold as a service with a margin on every hour — the contractor engages no subcontractor and buys no software — and it is one of hundreds of holders of this licence, naming none of the firms it staffs.

- Established: ÚRS CZ (KROS) (another site)urs.czÚRS — the KROS estimating program (another site)The most widespread Czech cost-estimating program sends a contractor's enquiries to subcontractors and compares their bids against the budget, with an AI assistant; it checks no worker's papers and pays nobody.
Sells KROS, the cost-estimating program it calls the most widespread in Czechia, used by thousands of people daily in construction and design firms and at public offices. Its OFERTA module sends enquiries to subcontractors and evaluates their bids, and a bid comparison app with an AI assistant checks them against the control budget. It prices the subcontracted work; it does not find crews, check workers' papers or pay anybody. ÚRS CZ a.s. has traded since November 1992.
- No source on file
Sells euroCALC, cost-estimating software for general contractors and building firms, with subcontractor enquiries, a side-by-side price mirror of their bids and AI functions. Like the program above it prices the subcontracted work and stops there: no crew sourcing, no document checks, no pay. Callida, s.r.o. has traded since April 1996; nothing on file shows who runs it.
- Early: cifro (another site)No source on file
Sells an AI junior estimator that prices a bill of quantities from the firm's own price lists and compares subcontractor bids. Before an enquiry goes out it shows what the business register and the VAT register say about the subcontractor firm, which is the nearest Czech product to a document check, but it checks the firm, not its workers. No company of that brand name was found on the business register, and no launch year is published.
- Early: RozpočetPRO (another site)No source on file
Sells online AI estimating by monthly subscription: it builds a bill of quantities from project documents, prices it from a market price database and lets a building firm compare prices from different subcontractors. It neither finds crews nor checks or pays them, and it publishes no launch year.

Makes it easier
- Contractors hire crews themselves.
- Matching a subcontractor firm needs no staffing-agency licence.
- The marketplace is ordinary software.
Makes it harder
- Established Czech firms already sell contractors their site diary, payroll and leads.
- Licensed staffing agencies already lease out crews with papers in order.

About this section
- What this shows
- What stands between you and the first sale: who buys, what permission selling needs, what it must plug into, and whether it needs outside money.
- Why it matters to a builder
- It tells you whether a small team can start selling soon, or needs a licence, a certification or funding first.
- How to read the score
- More points mean easier to enter: 3/3 is easy, 0/3 very hard. It is not added to the Opportunity total, and local competition does not count here: that is Market gap.
