Construction Change Order & Variation Software
Scope changes. Your margin shouldn't.
Raise the variation, see its price and its cost side by side, and route it through approval, all the way to the client, before anyone builds it. Approved changes land on the budget and flow into the next valuation automatically. On the record, in the numbers, in the payment.

Trusted by construction companies of every size, worldwide




























Every scope change priced and signed before it is built
Construction change order software puts every variation on the record before the work is done by pricing, approving and tracking each scope change in one system. Archdesk shows the price and the cost side by side, routes the change through approval to the client, then flows it into the budget and the next valuation automatically.

Margin impact visible before sign-off
Every variation shows its price and its cost side by side, whether it increases or reduces the scope of works, so you know what the change does to the margin before anyone agrees to it.
A clear instruction, not a verbal agreement
Approval workflows end with the client, whose sign-off is captured online before work starts. There is a paper trail nobody can argue with.
Approved changes reach the valuation on their own
Once signed, the variation adjusts the budget and flows into payment certification automatically, tracked from instruction to final payment.
The same disputes stop repeating
Variation analytics surface trends, root causes and claims exposure across the portfolio, so pricing sharpens with every project.
The work you deliver matches the work you bill
From instruction to final account, every variation is on the record, in the numbers and in the payment. Scope changes, and the margin holds.

Frequently Asked Questions: Change Orders & Variations
What does construction change order software do?
It puts every scope change on the record before the work is done. Archdesk prices each variation with its price and its cost side by side, routes it through approval all the way to the client, then flows the approved change into the budget and the next valuation automatically.
How does Archdesk handle variations that reduce the scope of works?
Variations are raised against the scope of works whether they add work or remove it. The cost impact is calculated at creation with supporting documentation attached, so a scope reduction is recorded and priced the same way as extra work.
When does the client approve a change order?
Before anyone builds it. Approval workflows route the variation through the right reviewers and end with the client, whose sign-off is captured online. Work starts on a recorded instruction rather than a verbal agreement on site, so there is a paper trail nobody can argue with.
What happens to a variation after it is approved?
The budget adjusts on approval and the variation flows into payment certification and the next valuation automatically. Each change is tracked financially from pricing to final payment, and approved variations are carried into the final account.
Can you see what variations do to margins across projects?
Yes. Variation analytics surface trends, root causes and claims exposure across the whole portfolio, so recurring disputes show up in the data and pricing sharpens with every project.
