Construction management software

From tender to payment.In one system.

Tenders, contracts, performance certificates, invoices and payments — on the same data. Your subcontractors join for free, NAV invoices arrive on their own, and you see the margin before the quarter ends.

The trial needs a bank card: a 100 Ft check, refunded immediately.

Sound familiar?

Projects don't slip on site. They slip in the office.

The certificate is typed in Word, sent by e-mail, and someone always signs the older version.

Everyone remembers the extra work differently. Especially at invoicing.

The deduction was fair. Its paper trail is a phone call.

The accountant tells you the margin. A quarter later.

The subcontractor builds from February's drawing. Precisely, on time.

NAV invoices wait in a folder for someone to finally match them.

How it works

One chain. Five links. None of them breaks.

Every step works from the previous one — nothing is typed twice.

Tender

Request and compare quotes

Request quotes from subcontractors and see them side by side in one table.

Contract

The winner becomes a contract

From the winning quote to contract, signature and amendments — all tracked.

Certificate

The certificate comes from the contract

With deductions, advance recovery, approval and signature.

Invoice

Invoices don't get lost in a folder

Incoming invoices come from NAV and link to the certificate; outgoing ones are made from the signed certificate.

Payment

Payments, cash flow, margin

Bank transfer batches, cash flow forecast, and the project margin live.

What it means for you

Money. Time. Order.

Money

See where it leaks.

Margin by work type, extra work, deductions and penalties in one place. The question isn't how much you made, but on which line it vanished.

Time

Less typing. Same number of signatures.

Certificates, contracts and letters come from templates; invoices from the certificate. Signing stays your job.

Order

One truth for everyone.

The project manager, finance and the subcontractor see the same number. "But they told me" ends here.

The modules

What each one does

One row per module: what it does and what it costs. Most of them come with a short recording — no sound, plays by itself.

Tender

One call, every subcontractor

Pick partners by trade and county, send the request for quotes in one click. Quotes arrive in a single matrix with a price comparison.

Included in Ultra
Contract

Signed from an email link, no paper

The partner signs from their own machine; the signature is recorded with a timestamp and IP address. The contract activates by itself.

Budget register

The budget goes in, the margin shows

Import the budget from Excel. From then on every trade shows its contract price, committed amount and margin — you do not find out at month end that it ran out.

Included in Ultra
Stargate

Your subcontractor works in the system too

They join for free, see the quoted amount, and accept or dispute each of your contract terms. They see their own part and nothing else.

Free in every plan
Blueprint

The defect sits on the drawing, not in an email

Drop a pin on the drawing with a photo and an owner. The cost of the repair carries through as a deduction on the completion certificate.

Included in Ultra
Defect tickets and deductions in ATMOS
Defects

The defect does not get lost in a group chat

A defect ticket with a photo and an owner. The cost of the repair carries through as a deduction on the completion certificate — it becomes a line item, not an argument.

Handling incoming and outgoing invoices
Finance

In from the tax office, out from the certificate

Incoming invoices arrive from the tax office feed; outgoing ones are issued from the completion certificate. Billingo and Számlázz.hu connect too.

Included from Pro
Financial reports by company and project
Reports

Revenue, margin, receivables

By company, by project, by month. Not a monthly spreadsheet merge, but one page that shows where the business stands.

Included in Ultra
Partners

You know who was good to work with

Quality, deadlines, communication — you score each aspect when the job ends. At the next tender that score sits next to the partner name.

HR

Leave is not kept in your head

The employee requests, the manager approves, the allowance decreases on its own. The calendar shows who will be around next week.

Included from Pro
Permissions

Everyone sees only what they need

Rights are switched per module. The site manager does not look at finance, and finance does not touch the drawings.

What it doesn't do

So you can believe the rest.

  • It's not accounting software.
  • It's not an e-construction log.
  • It's not design software.
  • It won't call the late subcontractor for you.

But it will show you which one it is.

  • Tendering and bid comparison in one place
  • Partner scoring, traffic light, blacklist
  • What other contractors actually experienced with the same subcontractor
  • The data going end to end: tender → contract → completion certificate → invoice. Five systems, five logins, and you are the copy-paste.

Side by side. From public data.

Six construction software products measured the same way: how much of a Hungarian contractor's daily work they cover, and what a 30-person team pays. Every mark and price is backed by the vendor's own page, with a date.

What about the big ERP systems?

They do a lot — for general purposes. For a contractor the question is how much time and money it takes to reach completion certificates.

FAQ

Worth knowing before you start.

If the answer isn't here, reply to the trial welcome e-mail — a human reads it.

14 days. Then you decide.
