Construction Billing & Accounting System

Unity Construction Accounting

Your projects grow. Your accounting should grow with them.

Start with the accounting you need today. Add deeper construction financial controls as projects become larger, longer and more complex.

Different Projects. Different Needs.

Not every contractor needs everything.

The financial needs of a contractor depend heavily on the nature and duration of its projects. Unity lets the system grow with the business instead of forcing every contractor into the same setup.

Shorter / Straightforward Projects

Start with a strong accounting foundation.

For straightforward projects, standard accounting together with project tracking and purchasing may be sufficient.

Longer / More Complex Projects

Add construction-specific financial control.

As projects become longer and more complex, add control over contracts, budgets, retention and the timing of revenue recognition.

Scalable by Design

Start. Grow. Scale.

A subcontractor may begin with trading or shorter projects, then grow into larger contracts or main-contractor work.

Project Budget Control

Don’t discover the overspend after the purchase.

Set project budgets and bring purchasing into the control process. Unity can check Purchase Orders against the relevant project budget before the cost is committed.

Budget functions can also support adjustments, provisional and contingency sums, approval and project budget analysis.

Recognised Revenue & Project Profit
For Longer-Term Projects

Progress billing is not always the same as revenue.

For longer-term construction projects, the amount billed may not represent the revenue to be recognised for that period.

Unity’s add-on module can calculate percentage of completion and support monthly recognition of contract cost and revenue, providing clearer visibility of project profit and supporting financial and tax-estimation planning.

Retention Tracking

Know what is being held — and when it is released.

Retention can remain outstanding long after the original work is billed. Unity helps contractors keep the retention trail visible.

Track retention involving both customers and vendors, including amounts held and subsequently released.

Project Contract Control

See the contract beyond the original contract sum.

Track the project contract, subsequent variation orders, billing activity and the remaining contract position.

Contract Details

Project title, contract number, tender number, dates and contract sum.

Variation Orders

Record positive and negative variations as the contract changes.

Billing Activity

Review invoice billing and relevant adjustments against the project.

Contract Balance

Bring contract sum, variations and billing together to understand the remaining position.

Customer Statement by Project

See what each project owes you.

Focus on the transactions and outstanding position relevant to an individual project, rather than only viewing the customer as one combined account.
