The problems we solve

What construction teams struggle with today.

Instalment billing is slow and wrong

The challenge today

Quantity surveyors merge quantities from many spreadsheets and work out retention, advances and deductions by hand; the owner sends it back.

How it's designed to work

Each instalment is built from signed-off quantities, with the deduction order shown for checking before the invoice is issued.

Billing

Retention money gets lost over time

The challenge today

Nobody chases retention held by the owner once the warranty ends, and subcontractor retention is paid back even with defects still open.

How it's designed to work

A retention register for receivable and payable, with due dates, a monthly list of items due, and no release to a subcontractor with open defects.

Retention — prototype screen, sample data
Retention

Profit or loss is unknown until the job closes

The challenge today

Material, labor, plant and subcontractor costs arrive late, with no commitments and no estimate at completion.

How it's designed to work

Tracks budget, commitments, actual cost and estimate at completion per project and work location, with forecast gross profit each month.

Cost — prototype screen, sample data
Cost

Extra work done but not paid

The challenge today

Work follows site instructions without paperwork, and its cost mixes with contract work.

How it's designed to work

A clear status for each variation, cost of work done before approval always kept apart, and the value still at risk visible per project.

Claim — prototype screen, sample data
Claim

Subcontractors overpaid

The challenge today

Retention, advances and back-charges are not fully deducted, and payment goes out before the work is accepted.

How it's designed to work

Pays only after a three-way match with accepted work, deducts retention, advances and back-charges, and allows payment holds.

Sub pay — prototype screen, sample data
Sub pay

Public-sector work has its own rules

The challenge today

K-factor is worked out in spreadsheets, and bid and contract guarantees do not show the remaining limit.

How it's designed to work

A tender register with e-GP number, Factor F tables, K-factor per instalment with the indices used, and remaining guarantee limit per bank (Enterprise).

What makes it different

Designed around how construction really runs.

Revenue follows accepted work, not goods delivered

Designed so billing follows signed-off quantity per BOQ line, with the claimed-versus-accepted variance visible on every instalment.

Every instalment has its own deduction chain

Designed to calculate retention, advances, K-factor, damages and deductions in order and show them before the document is issued.

Retention and advances run both ways

Designed to cover the owner side and the subcontractor side, with due dates, caps and release conditions.

The BOQ is the heart

Designed with a BOQ tree you can paste from a spreadsheet, unit-rate analysis from material, labor, plant and subcontract, and a total that must equal the contract value.

Cost per project and work location

Designed to show budget, commitments, actual cost and estimate at completion per zone, floor and cost category.

Closing a project has real conditions

Designed so open costs must be handled, retention and guarantees need release dates, and gross profit needs a second approver before a project closes.
