Margin leak bingo

Things that can quietly nibble away at construction project margin:
+ Materials ordered but not properly allocated
+ Plant left on hire longer than expected
+ Subcontractor variations not tracked clearly
+ Labour costs arriving late
+ Retentions forgotten until someone asks
+ Purchase invoices coded to the wrong place
+ “Small extras” that stop being small
+ Reports that only show part of the picture

If you got a full house, please collect your prize: a strong cup of tea and a conversation about Pegasus CIS 5.

Pegasus CIS 5 brings together contract costing, purchasing, plant hire, subcontractors, labour, stock, sales and reporting to help construction businesses understand job performance more clearly.

Because margins rarely disappear in one dramatic moment.

They usually leave quietly, wearing a hi-vis jacket.

Actual costs, committed costs and the bit in between

One of the most dangerous gaps in construction finance is the gap between what has already been posted and what has already been committed.

Posted costs tell you what has happened.

Committed costs tell you what is coming.

If you only look at posted costs, a job can look healthier than it really is.

Pegasus CIS 5 supports committed costs from suppliers and subcontractors, purchase orders, purchase invoice register activity, plant hire, stock, labour and direct costs.

That means project and finance teams can get a more complete picture of the job, rather than waiting for every invoice to arrive before they know where they stand.

And in construction, waiting for every invoice before understanding the margin is a bit like checking the weather after you have poured the concrete.

Want better visibility of actual and committed costs? Let’s talk Pegasus CIS 5.

What makes job costing powerful?

Job costing becomes powerful when it gives you more than a list of costs.

It should help you understand:
~ Where the cost came from
~ Which job it belongs to
~ Which phase it relates to
~ Which cost heading it affects
~ How it compares to budget
~ What has been committed but not yet invoiced
~ What the likely outcome is

Pegasus CIS 5 allows jobs to be divided into job heads and phases, with budgets, revenue, costs to date, actual-to-budget variance and reporting. It also supports original and revised budgets, period-based budgets and revenue budgets for cashflow forecasting.

That gives construction teams a more structured way to manage job performance, rather than trying to reverse-engineer the truth at month-end.

Good job costing does not just report the past.

It helps you protect the future margin.

When did you last spot a margin issue early?

A question for construction finance and project teams:

When did you last spot a margin problem before it became a proper problem?

Not after month-end.
Not after the QS asked awkward questions.
Not after the project manager said, “That cannot be right.”
Before.

That is where good job costing earns its keep.

Pegasus CIS 5 helps construction businesses monitor job financial performance by recording direct costs as well as costs from labour, purchasing, plant hire, stock and subcontractors. It also supports actual-to-budget variance reporting, projected costs to complete and contract revenue reporting.

Because margin control should not depend on luck, instinct or the most up-to-date spreadsheet being open on the right person’s machine.

No hard sell. No jargon fog. Just a practical look at what better contract control can look like.

Signs your job costing process may need help

A few gentle warning signs:

You have a spreadsheet called “Final Final Latest Actual Final.xlsx”.

Nobody can explain column M.

Month-end reporting involves three people, two exports and one quiet panic.

The phrase “I thought that had been posted” is heard weekly.

Someone says “committed costs” and everyone looks at the purchasing person.

The retention report is somewhere. Probably.

If any of this feels painfully familiar, Pegasus CIS 5 might be worth a serious look.

It is designed to help construction businesses manage contract costing, purchasing, sales, subcontractors, labour, plant, stock and reporting from one integrated system. [CIS 5 brochure | PDF]

Because construction accounting is challenging enough without your spreadsheet developing a personality.

One system for contracts, costs and project visibility

Pegasus CIS 5 is not just a costing system.

It brings together many of the moving parts that construction businesses need to manage every day, including:
~ Contract costing
~ Contract purchasing
~ Plant hire
~ Contract sales
~ CIS subcontractors
~ Labour and timesheets
~ Stock control
~ Management reporting and dashboards
~ Document management
~ Integrated accounting

The Pegasus brochure describes CIS as a central solution for managing payments, receipts, retentions, cashflow and management reporting across contracts.

That joined-up approach is important because the cost of a job does not live in one tidy place.

It lives in purchase orders.
It lives in subcontractor applications.
It lives in timesheets.
It lives in plant hire.
It lives in stock issues.
It lives in sales applications, certificates and retentions.

Pegasus CIS 5 helps bring those moving parts together, giving your finance and project teams a clearer picture. Download the Pegasus CIS 5 brochure or speak to o-a-sys for a guided overview. https://zurl.co/spOxQ
