Construction

The state of every crew in one place

Subcontractors report progress from a phone, upload protocols and certificates, flag clashes and submit interim invoices against approved quantities. You stop chasing emails and phone calls.

Does this sound like your subcontractors?

Progress reported by phone, if at all

The site manager calls the foreman, the foreman says "we finish tomorrow". The schedule depends on who remembers the call how.

Interim invoices without measured quantities

The subcontractor invoices the stage as nearly done, the site manager sees half. Two weeks of negotiation, and accounting does not know what to post.

Half the documents missing before handover

Test protocols, certificates, statements that sub-subcontractors have been paid. Gathered the week before handover, one email per company.

Eight parts that make up the portal

The portal shows the subcontractor their scope and shows you the state of every crew. We set the scope around what blocks handovers and settlements most today.

Subcontractor card

Contract, scope from the BoQ, schedule, retention, liability insurance, workers' qualifications and safety training. An expiring policy or medical check lights up on the list before the inspector asks.

Progress report from a phone

The foreman marks items done, adds a photo and a measured quantity. The site manager confirms or corrects. The crew's progress enters the site schedule the same day.

Partial handovers and protocols

Notice of readiness for inspection, a snag list with photos, a deadline to fix, a signature on a tablet. The works handover protocol is generated from the system.

Interim invoices against measured quantities

The subcontractor can invoice only approved quantities. The system calculates the retention and shows how much of the contract remains.

Clashes and reports

The crew reports a clash between disciplines, no work front or missing material, with a photo and a pin on the drawing. The report reaches the site manager and the crew it concerns.

Handover documents

A list of required documents per scope: test protocols, certificates, declarations of performance, statements of no arrears towards sub-subcontractors. The subcontractor sees what is missing and uploads it themselves.

Crew schedule and work fronts

Who follows whom and when. One crew's slippage immediately shows which next crew will have no work front.

Subcontractor rating

Punctuality, snags at handovers, document completeness, quantity disputes. At the next tender you choose from data rather than memory.

What AI does in the subcontractor portal

Three years ago features like these needed a data science team. Today language models read emails, documents and photos, and we build them into the system we make for you. Below is what makes sense in this solution. A person approves, AI prepares.

Report photos compared with the claim

AI looks at the photos in a progress report and compares them with the declared percentage and with earlier reports. A mismatch reaches the site manager as a question, not a decision.

Example report "3rd floor plastering, nearly done" with a photo showing two unplastered walls → flag "for site manager confirmation" with a comparison to yesterday's photo

Subcontractor invoices read and compared

The PDF of an interim invoice becomes data: items, amounts, period. The system sets it against the approved quantities and the contract and highlights the differences.

Example invoice for 184,000 PLN → approved quantities worth 162,000 PLN, retention not deducted, two flags before posting

Subcontractor questions without calling the site manager

An assistant in the portal answers questions about start dates, work fronts, the current revision and invoice status from system data.

Example "when do we start on the 4th floor and is there a new services revision?" → "work front ready from Thursday, E-04 revision B current since 12 March"

Document set checked before handover

AI reads uploaded certificates and protocols, recognizes what they cover and ticks off the required list. Missing ones trigger a reminder to the subcontractor.

Example 14 files from the plumbing contractor → 11 recognized and filed, pressure test protocol and valve declarations missing, reminder sent

Effects you see in the first month

  • Crew progress enters the schedule the same day, because the foreman reports from a phone and the site manager only confirms
  • An interim invoice reaches accounting with measured quantities and the retention calculated, so the percentage dispute ends on site
  • The handover document set builds up throughout the project, not in the week before
  • You pick a subcontractor for the next site from their record of handovers and deadlines
What it connects to

The portal feeds on data from your systems

Contracts and scopes from the project system or Excel, invoices to the ERP and KSeF, company register entries and the VAT whitelist checked automatically. Subcontractors log in from a phone with nothing to install.

From progress report to invoice

The first version answers the question you ask every day: where is each crew. Invoices, documents and ratings follow once subcontractors are already reporting.

01

Analysis and scope

We sit down with the site managers and the person who settles subcontractors. We write down how a report, an invoice and a document set arrive today, and what blocks handovers.
2 weeks
02

Reports and handovers for one site

A portal with login, subcontractor cards, progress reports from a phone, clash reports and partial handovers. We start with the subcontractors of one site.
6–8 weeks
03

Invoices, documents, ERP

Interim invoices against quantities with retention, the handover document list, handoff to the ERP and KSeF, subcontractor ratings.
4–6 weeks
04

Subcontractor onboarding

Invitations, a one-page guide, phone support for foremen during the first reports. Further sites join with their own subcontractors.

Does your company run on Excel, emails and a system from years ago? We will build the solution that puts it in order, with AI inside from the start.

You have the diagnosis, we build the solution. Web applications, B2B portals and automations for companies without a large IT department. Today a system can read emails and documents, suggest decisions and answer customers on its own, so we build that in from the first version, not as an add-on a year later.

We agree scope, price and dates upfront, show progress every week, and the code and data stay yours.

  • scope, price and dates upfront
  • progress every week
  • your code and data

Common questions

Will subcontractors actually use it?
If a report takes longer than a phone call, no. That is why the foreman has one screen: item, percentage, photo. The strongest argument is a contract clause saying interim invoices come in only through the portal. Then everyone reports.
What about a subcontractor with five people and one site?
They log in from a phone through a link sent by text message, with no password to remember and no app to install. Uploading a certificate means taking a photo of the sheet.
Does the portal replace our project management system?
It extends it. If you have a system, or we build one alongside the portal, subcontractor progress enters the site schedule. If the schedule lives in MS Project, we import the scopes from the file.
Who owns the code and the data?
You do. The code is in your repository, the data in your database on servers in Poland or the EU. A subcontractor sees only their own contract, scope and invoices.
What does maintenance cost?
Hosting and monitoring are a fixed monthly amount, with no fee per subcontractor, so you can invite all of them. Changes are billed by the queue you set.
