The Financial Detective Keeping New York Moving

When I tell people I write for a construction consultancy firm, they immediately conjure up images of grit and steel: massive cranes punctuating the skyline, architects rolling out blueprints, and engineers in hard hats directing the show.
But ask anyone who has been in this business for more than a week, and their mind goes somewhere else entirely. They think about the lifeblood of the project. They think about cash.

And I don’t mean that in a greedy way.
I mean it in a logistical, terrifying way. In major capital construction, cash flow is gravity. If the money stops moving, the cranes stop moving. Suddenly, you aren’t thinking about steel beams; you are thinking about thousands of invoices flowing in like a tidal wave and the shadow of an audit always hovering overhead.
For a massive capital construction project, Engineering Financial Specialists are just as critical as the structural engineers. If the engineer fails, a column might collapse. If the financial specialist fails, the entire project loses its budget, its vendors, and its momentum.
At Toll International LLC, we pride ourselves on our world-class technical team. And today I want to highlight one of these brilliant minds: Nikky, a Principal Contract Support Specialist for our Invoice Management team. She sits at the intersection of massive budgets and microscopic details on some of our most critical Port Authority of New York and New Jersey (PANYNJ) projects.
I caught up with Nikky to talk about the "detective work" behind the construction sites we walk past every day.
Digital work, physical results
Construction finance can feel strangely removed from the jobsite. Your day is a sequence of cost codes, contract lines, SAP screens, spreadsheet trackers, and approval queues. It is black-and-white data.
And yet, those numbers represent real objects with real weight: steel deliveries, traffic control, electrical gear, concrete testing, safety equipment, equipment rentals, and the labor that installs it all.
I asked Nikky what it feels like to contribute to a bridge, tunnel, or airport improvement from behind a screen.
"It’s an unspoken feeling," Nikky told me. "When I get a chance to travel, whether it's through the airports, going over the bridges, or through the tunnels, it all becomes vivid."
For Nikky, a bridge suddenly becomes more than a way to get across a river. It is a timeline of completed tasks. "I know the work that goes into the project," she explains. "I see the different stages until completion. Knowing that the invoices I process on a day-to-day basis generated the payments that contributed to this work meeting deadlines... it brings it to life."
This is the hidden satisfaction of the role. When you and I drive through a tunnel, we see concrete and lights, and we might guess that engineering was involved. When a specialist like Nikky drives through, she sees the intricate navigation of complex procurement, the vendor relationships kept alive by timely payments, and the repair work that ensures safety.
Sounds a little bit like the Matrix… she sees the numbers behind the world.
Where the Numbers Pile Up
It is easy to underestimate the sheer scale of "paperwork" involved in public infrastructure. Working with the Port Authority of New York and New Jersey isn't like balancing a checkbook.
The task brings on some hefty volume.
I asked Nikky to give us a sense of the volume she handles.
"There is a lot of work being done through The Port Authority," she notes eagerly. "On a weekly basis, my unit alone can process over 150 invoices."
Let’s pause on that number. 150 invoices a week.
If you work in a standard corporate office, processing an invoice might mean glancing at a PDF and hitting "approve." In Nikky’s world, an invoice is a forensic investigation.
Every single one of those 150 documents represents a vendor waiting to be paid, a contract clause that must be adhered to, and a specific budget code that must be accurate.
"All invoices are audited and high priority," Nikky says. This is the meat of the matter, the source of the pressure if you will. In this environment, you cannot simply "push paper." You have to possess a detective’s eye for detail.
A typical invoice review can include verifying items like:
Vendor and contract alignment Confirming the invoice is billed to the correct vendor record and the correct contract, including the right contract line, task, or work package.
Coding that ties to the budget Ensuring the cost is charged to the correct project identifiers, cost codes, and budget buckets so the program’s reporting stays accurate. One wrong code can distort forecasts, contingency tracking, and monthly cost reports.
Scope and rate validation Checking that the billed work matches the contract terms: agreed unit rates, labor categories, markups, and reimbursable rules. Small inconsistencies add up quickly at scale.
Time period and backup documentation Verifying service dates, delivery tickets, timesheets, inspection reports, or other support that demonstrates the work was performed and accepted.
Status of approvals and change control Confirming that anything billed outside the original scope is supported by an approved change mechanism, not just an email thread.
Payment terms and timing Tracking net terms and making sure invoices move through the workflow fast enough to avoid avoidable late payments, while still maintaining compliance.
This is also where judgment matters. Construction billing is messy because construction itself is messy. Work can be staged, partial, reworked, remeasured, or delayed by factors that have nothing to do with the vendor’s performance.
Nikky’s job is to apply consistent rules inside inconsistent reality.
In Nikky’s hands rests the outcome of the entire pipeline. "They have to be processed in a timely manner so payments can go out to the vendor before their net terms," she explains. This is where the job becomes deeply human.
Nikky processes numbers, but she understands what they really are; they are livelihoods. If Nikky’s team slows down, a small-business vendor won't get paid on time. Keeping that flow moving requires a level of focus that goes unnoticed by the outside world.
The Guardian of the Hub
Why do it? Why take on the stress of audits, the avalanche of paperwork, and the pressure of "net terms"?
For Nikky, it comes down to civic pride. We aren't just building an office block; we are maintaining the arteries of one of the most important economic centers on Earth.
"The most satisfying feeling I get is knowing that we have the budget to have new construction, repairs, and maintenance done around the metropolitan area," Nikky says.
She views her role as essential to the ecosystem of New York and New Jersey. "This is one of the biggest tourist and economic hubs in the world. We are providing access to transportation—bridges, tunnels, airports, and ports. Our department's work is essential to processing payments to those vendors that support our efforts."
The Unsung Heroism of "Back Office"
In the construction industry, we often reserve our applause for the ribbon-cutting ceremonies. We take photos of the architects and the politicians. But perhaps we should save a little applause for the moment a complex invoice batch is cleared at 4:00 PM on a Friday.
Nikky’s experience reminds us that "building" is about more than welding steel. It’s about stewardship. It’s about the integrity of the financial process that allows the steel to be bought in time in the first place.
At Toll International, we know that if you want to see the skyline change, you need people who can handle a crane. But if you want the project to actually finish, you need people like Nikky handling the numbers.
