Why DCT-OS — the power moves

A quick look at the shortcuts and flow that turn a desk full of dockets into live project cost — see why it's worth it.

What it does

Everything you need to track project cost. Nothing you don't.

No enterprise bloat, no per-seat licence, no two-week onboarding. Open it and start entering dockets.

A cost model that fits the job

Three clear axes — Work Orders for client scope, Cost Codes for your budget, Purchase Orders for committed spend. Every docket line lands in the right place.

Dockets that match the paper

One docket, many lines — exactly like the delivery slip in your hand. Pick plant and labour from your resource list and the detail fills itself in.

Rate review at invoice time

Site dockets carry quantities, not prices. When the invoice arrives, confirm the rates in one screen — and your rate library stays current for next time.

Budgets and burn at a glance

Every cost code shows budget, actual, variance and burn — live, as you enter. No spreadsheet gymnastics, no month-end surprises.

Your rates, your suppliers

Build a resource library with standard rates, and keep supplier names tidy and consistent. Import what you already have in Excel in one click.

Reports built for claims

Summarise spend by supplier, tag what you've claimed, and export clean CSV or Excel — ready for the invoice run or the monthly report.

How it works

From the ute to the budget in three steps

1

Enter the day's dockets

Date, supplier, and the lines off the slip — plant, labour, materials with quantities. Keyboard-driven, seconds per docket.

2

Confirm rates when invoiced

Open the supplier's summary, check the rates against the invoice, and accept. Costs update everywhere instantly.

3

Watch the budget, claim with confidence

Cost codes show live burn; reports group spend for the claim. Export and you're done.

Designed for the way site work actually happens

Most cost software assumes a back-office accountant with time to spare. DCT-OS assumes a busy engineer with a stack of dockets and a budget to protect.
