Four Services That Could Help Prime Contractors Verify Wages

Wages will start moving separately from construction payments

From January 1, 2027, a wage-segregated payment system (임금구분지급제) will apply to certain contracted construction and shipbuilding projects in Korea. Under a 2024 amendment to the Labor Standards Act, prime contractors must pay the wage portion of contract payments separately each month and verify that subcontracted workers actually received their wages.

Subcontractors cannot use money received for wages for other construction costs or operating expenses. If a prime contractor finds unpaid wages, it must report this to the Ministry of Employment and Labor (고용노동부), Korea’s labor ministry. This means companies need to manage not only how money is split and paid, but also the evidence collected after payment.

Under standards proposed by the Ministry of Employment and Labor in August 2026, the system covers certain contract projects lasting more than 30 days. In construction, it is connected to the scope of the client direct-payment system, but the exact monetary threshold for private projects must be checked against the final lower-level regulations.

In shipbuilding, the system is expected to be phased in based on the original order value of an individual vessel. Under the ministry’s announcement, it will cover vessels worth KRW 50 billion or more in 2027, KRW 24 billion or more in 2028, and KRW 12 billion or more in 2029.

Prime contractors can verify payment using documents such as wage statements and social insurance payment records. The proposed rules also include a plan to treat payments made through an electronic payment system as fulfilling the obligation. That means a new service may be more realistic if it first helps companies produce accurate materials for government or project-owner systems, rather than trying to replace those systems.

The new buyer may be the prime contractor’s finance or labor team

Korea’s 2027 wage-segregated payment system could make finance and labor staff at prime contractors potential buyers. A small service that reconciles subcontractor attendance, payroll, and bank-transfer records in one place may become easier to sell. Because the law places verification responsibility on the prime contractor, solving its monthly closing problem first may be more viable than trying to persuade subcontractors alone.

Consider a window-installation subcontractor with 18 employees. Each day, the site foreman writes down who showed up and how many days they worked in a paper attendance log. An office worker then copies those details into an Excel payroll sheet and separately stores wage statements and bank-transfer records.

When the prime contractor asks for payment-verification documents, staff must find the same person’s name and amount again across the attendance log, payroll sheet, wage statement, and transfer record. If a foreign worker’s Korean and English names differ, or if a work date has been corrected, they need to confirm which record is right through calls and messages.

Once the system begins, this will no longer be work done only when a problem appears. It will become a monthly closing task. The workflow needs to calculate the wage cost to claim from the month’s workdays and agreed wages, then attach each worker’s transfer record after payment and create a submission package for the following month.

The person spending money on this is not only the subcontractor’s owner. A prime-contractor manager overseeing several subcontractors at one site will want to see, at a glance, which companies have completed submission, which have mismatched amounts, and which are missing payment evidence. They will also need to explain their work performance through whether verification was completed on time and unpaid wages were not missed.

That could change the sales model. You could test two routes: the prime contractor pays per site and gives subcontractors free data-entry screens, or subcontractors required to submit materials in the prime contractor’s format buy a submission tool only in the months they need it.

Not every judgment can be automated. Disputes over actual work dates, changes to daily wages, the legitimacy of advances and deductions, and checks for people with identical names still need human handling. The service should focus on flagging suspicious items and recording who changed what, and when.

In the United States, project owners and prime contractors adopted systems

The U.S. Department of Energy provides LCPtracker for wage reporting in federally supported infrastructure projects. Recipient organizations and contractors can enter weekly payroll data or upload existing payroll files, then review error flags for wages, overtime, apprentices, and fringe benefits.

Because the Department of Energy provides the tool centrally, individual subcontractors do not pay separate fees. The department says it can connect data from more than 20 payroll programs. This shows a route where, instead of seeking every small subcontractor as a customer, a company sells to one organization responsible for managing the obligation.

There is also an example of a private prime contractor adopting a construction-payment system. U.S. company ARCO Construction used Oracle Textura Payment Management to handle subcontractor billing, document checks, and electronic payments in one place. Its structure charged subcontractors fees based on contract value.

In Oracle’s own announcement, ARCO’s payment-processing time fell from 65 days to 45 days, while overtime fell to one-fifth of its previous level. These are company-published figures and need separate verification, but they clearly show that a prime contractor may buy because it wants to reduce payment delays and month-end verification work, not simply because of a legal explanation.

Four things to build now

1. A wage-evidence package builder for subcontractors

This service matches attendance logs, payroll sheets, wage statements, and transfer records by worker to create files for submission to a prime contractor. It is for specialist construction subcontractors with five to 30 employees that use both paper attendance logs and Excel payroll sheets.

As monthly verification repeats, they will need a tool to find missing items and match identical names. The first screen should place each month’s worker list alongside workdays, expected payment, actual payment, and whether evidence has been attached.

2. A missing-submission and mismatch dashboard for prime contractors

This service shows how far each subcontractor has progressed through wage-cost claims, payment, and evidence submission. It is for finance and labor staff at private construction prime contractors that manage several specialist trade contractors at one site.

Since verification and unpaid-wage reporting obligations fall on the prime contractor, finding missing subcontractors before the deadline becomes the reason to buy. The first screen should prominently show three statuses for each company alongside its submission deadline: not submitted, amount mismatch, and verification complete.

3. A mobile payment-confirmation screen for workers

This service lets workers check their workdays and payment amount, then immediately flag incorrect names, accounts, or amounts. It is mainly for day laborers who move between sites and foreign workers whose records may contain both Korean and English names.

Even if the prime contractor’s and subcontractor’s ledgers match, the actual payment information may differ. Workers need a way to confirm the information before and after payment. The first screen should show the site name, workdays, expected payment date, and payment amount, with only two buttons: confirm and request correction.

4. A contract-by-contract eligibility and preparation schedule guide

This service takes contract information and shows the likelihood that the system applies, along with the monthly tasks to prepare in sequence. It is for contract managers at prime contractors reviewing private construction contracts from 2027 onward, and owners of specialist construction companies that have won new work.

The final monetary threshold and submission method for construction projects may vary under lower-level regulations. Companies need a tool that helps them avoid missing the latest rules from the point of contract signing. The first screen should have five fields—industry, client type, contract date, construction period, and contract value—plus the likely applicability and the next review date.

Ask one prime-contractor manager today

Call one finance or labor manager you know at a construction prime contractor. Ask how many types of files they opened to verify subcontractor wages over the past month, and what reason caused them to return submissions most often. You do not need to obtain actual documents; spending 20 minutes hearing only the file names and workflow order is enough.

If people are manually comparing three or more types of material, or if name or amount mismatches led them to ask the same company for corrections more than once, this is worth building first. In that case, the first product should not be a large system that replaces all payroll. It should begin as a small submission tool that gathers existing files and flags only the mismatches.

Why this matters where you are

This is a Korean regulatory change: the verification duty, payment rules, and phased shipbuilding thresholds are specific to Korea. In your market, check who carries responsibility for verifying contractor or subcontractor wage payments, what evidence they must collect, and whether a government or project-owner system already exists. If the same records are still reconciled manually each month, a narrow tool that prepares submissions and flags discrepancies may be more useful than a full payroll replacement.
