For subcontractors and trade contractors

Many jobs at once. One list that shows which ones make money

As a subcontractor you run twenty projects in parallel on thin margins, and the money disappears in changes that never got invoiced. AIMZ gives you margin per job, control of self-performed work hour by hour, and changes followed all the way to invoice – without the project manager keeping spreadsheets in the evening.

The challenge

The margin is thin, and what eats it is not the job itself

A trade contractor with twenty jobs on the go has no time to run each of them as a project in its own right. So changes are notified verbally, invoiced too late or not at all – and the result on the job is only known once it is finished.

Changes that never got invoiced

The work is done and approved verbally on site, but the claim was never sent. The amount is lost, and nobody knows how much it adds up to.

Too many jobs, too little time

Twenty jobs on the go and one project manager on each. Tracking is done from memory, and the result comes as a surprise when the job is finished.

Counterclaims you cannot document

The general contractor deducts for delays or defects. Without documented notices and dates, the discussion becomes one word against another.

How AIMZ works

Built for many jobs and little administration

01

All jobs in one list, with margin per job

Contract sum, accrued cost, completion rate and forecast per job – updated by the invoices already in the ledger. You see which jobs are going well, which are slipping, and which need attention this week, without opening twenty spreadsheets.

Changes get invoiced, not forgotten

Every change is followed from notice to payment: notified, priced, approved by the general contractor, invoiced. What remains uninvoiced is a number you see every day – not something you discover at final settlement when the deadline for claiming has passed.

Costs land on the right job by themselves

AIMZ reads incoming invoices, recognises the supplier and suggests which job and line item they belong to. You approve or change the suggestion, and the forecast updates at the same time. It is tracking that keeps itself current without anyone maintaining it.

Self-performed work is where the margin is actually decided

For a trade contractor, the biggest cost is people, not purchases. AIMZ takes the hours from timesheets onto the right job and line item, prices them at the real hourly cost, and sets hours spent against quantity produced. Then you see actual unit cost against estimate – while the job is in progress.

Trades

Trades that track self-performed work in AIMZ

The units you measure production in are set per trade, so estimated and actual unit cost are comparable.

Electrical
Points, containment and switchboards as separate production line items.
Plumbing and HVAC
Metres of pipe and number of units against hours spent per zone.
Ventilation and cooling
Air handling units, ductwork and commissioning separated in the estimate.
Concrete and groundworks
Cubic and square metres with labour and plant in the same line item.
Carpentry and fit-out
Piecework and fixed pay priced at the real hourly cost.
Roofing and waterproofing
Square metres of roofing against hours, per section and construction phase.
Infrastructure and civil works
Roads, rail and energy facilities – metres of trench, cable and foundations against labour hours and plant hours.
AIMZ puts us in a strong strategic position to face the future. The days of financial tracking in Excel are over, and we need to get on this train now.

Questions we often get

We have lots of small jobs. Is AIMZ too heavy for that?

No. A job is set up with a contract sum and a few line items, and the rest comes from the invoices already in the accounting system. Small service jobs can be tracked with contract sum and accrued cost, without a full budget structure.

Can we see margin per job and not just per company?

Margin per job is the main view in AIMZ. You see contract sum, accrued cost, forecast and margin for every job, and can sort the portfolio by what is slipping first.

How does AIMZ help us get paid for changes?

Every change has a status from notified to invoiced, with the notice date documented. Approved changes that have not yet been invoiced are shown as a separate number, so they are not forgotten before the deadline passes.

We use Tripletex. Do we have to switch?

No. AIMZ fetches invoices and vouchers from Tripletex and other accounting systems, and lays the project finances on top of them. Bookkeeping continues where it is today.

How does AIMZ track self-performed work and hours?

Hours are fetched from timesheets and placed on the right job and line item, at the real hourly cost including on-costs and mark-up. Hours spent are set against quantity produced, so actual unit cost can be compared with the estimate while the job is in progress.

Does AIMZ separate self-performed work from bought-in and hired-in?

Yes. Your own hours, hired-in labour, materials and subcontractors sit as separate cost types on the line item. You see how much of the job you produce yourself, and which part of the margin comes from it.

Can project managers use it from the site?

Yes. Approving invoice suggestions, registering changes and looking up the numbers all work from a phone, so tracking happens between two sites and not in the evening.
