Winning More Cell Tower Work Can Make Your Cash Flow Worse

For a cell tower contractor, growth can create a strange problem.

You add another crew. Take on another site. Revenue goes up. The order book looks stronger than it did six months ago.

And you have less cash.

Tower work consumes cash before it produces it. It is part of a wider working capital problem facing cell tower and fiber contractors. Crews need to be paid. There is equipment, materials, travel and subcontractors. Then the work has to be completed, documented and approved before the invoice starts making its way through the customer’s payment process.

The amounts involved aren’t small. Industry analysis from Dgtl Infra puts the average cost of building a new U.S. cell tower at around $250,000, with a typical range of $200,000 to $300,000. Of that, it estimates $110,000 to $165,000 can sit in site construction alone, including foundations, tower erection and site access. Dgtl Infra

Not all of that expenditure sits with one contractor, of course. But it gives some scale to the projects these businesses are helping deliver.

The bigger the job, the bigger the gap

The difficulty is timing.

A tower contractor can be paying crews and suppliers while completed work is still going through closeout, approval and invoicing. Put several sites into a rollout at the same time and that working-capital requirement can build quickly.

And payment terms are part of the problem.

In a 2024 account published by Fierce Network, a long-time tower contractor described payment terms moving from net 30 historically to 45 days being considered favourable and 60 days becoming common. The contractor also pointed to another delay: final invoices cannot necessarily be submitted immediately when physical work finishes because closeout and approval still need to happen.

The issue hasn’t disappeared. In July 2025, Fierce Network reported on research commissioned by NATE, the Communications Infrastructure Contractors Association, which identified delayed payments and extended payment terms among the pressures facing tower contractors. Fierce Network

This is how a profitable contractor can find itself worrying about Friday’s payroll.

One large customer can complicate things further

Telecom contractors frequently build their businesses around a relatively small number of large customers.

That can make conventional financing harder. A lender looking at a contractor with most of its accounts receivable sitting with one customer may see concentration risk.

There is another way of looking at it.

If that customer is financially strong and the invoices represent completed, accepted work, those receivables can themselves become a source of working capital.

TowerCap is comfortable funding businesses with high customer concentration, including facilities where a single debtor accounts for the eligible receivables.

Turn the invoice into working capital

Invoice factoring allows a contractor to convert an eligible unpaid invoice into cash rather than waiting through the customer’s normal payment cycle.

That cash can go back into payroll, equipment, suppliers, subcontractors or the next site.

Importantly, the available funding can grow alongside the receivables. Winning more work therefore doesn’t necessarily mean repeatedly asking a bank to increase a fixed credit line.

TowerCap can advance up to 85% of eligible invoice value. Clients can choose which invoices they want to factor, without committing to a minimum factoring volume.

For qualifying businesses, TowerCap can also provide non-notification factoring. That can matter in telecom, where the contractor may not want its financing arrangements inserted into a long-standing customer relationship.

When growth outruns cash

There is nothing unusual about a cell tower contractor waiting to be paid.

The problem starts when the contractor’s ability to win and perform new work begins moving faster than its cash conversion cycle.

On a project where the underlying economics can run into hundreds of thousands of dollars, 45 or 60 days is a long time to carry the gap.

The question isn’t whether the contractor has enough work; it’s whether it has enough working capital to keep saying yes to it.
