A working capital loan gives an Ardmore, OK service company a lump sum to cover payroll and running costs, paid back in fixed installments over a set number of months; a line of credit instead lets it draw only while an operator invoice is open. Windpoint Business Funding sends the request to funding partners, and each partner decides whether it looks at oilfield service work.
Why operator invoices can take weeks, how a working capital loan and a credit line compare for crew payroll in Ardmore, OK, and what customer concentration means to a funding partner, with invented figures computed.
Why operator invoices can take weeks to pay
The work is done in days; the money follows on the operator's schedule. A field ticket has to be signed at the site, the invoice has to match the purchase order, and the operator's payables team can route it past several desks before it is paid on the terms in the master service agreement. A ticket disputed over hours or materials goes back to the start of that line.
- The job ends and the operator's site representative signs the field ticket.
- The office invoices against the purchase order, with the ticket attached.
- The operator's payables system checks the invoice, and it can wait there for coding or a manager's sign-off.
- Payment is released on the terms in the master service agreement, which can run 30, 45 or 60 days or longer.
The part a service company controls is its own paperwork. An invoice sent on the day the ticket is signed, carrying the purchase order number and every attachment the operator's system expects, starts the payment clock sooner. A simple log of submission dates later shows which delays sat with the operator and which sat in the company's own office.
Payroll does not wait for any of those steps. In 2023 the 52 Carter County, OK establishments under NAICS 213112, support activities for oil and gas operations, paid $31.6 million in annual payroll to 472 people on the March pay period roster (County Business Patterns), which works out, by our arithmetic, to roughly $67,000 a year for each person on those payrolls. The oilfield services industry page breaks those figures down further.
Working capital loan vs credit line for crew payroll
Illustration only, invented figures: a crew with a $18,400 biweekly payroll finishes a job billed on 45-day terms. Whether 3 or 4 paydays land inside those 45 days depends on the calendar, so the crew in this example fronts $55,200 to $73,600 in wages before the operator's check comes in.
| Measure | Working capital loan | Line of credit |
|---|---|---|
| Amount | $60,000 received once | $18,400 drawn on each of 3 paydays |
| Invented annual rate | 16% | 13% |
| How it is paid | 12 payments of $5,443.85 | Balance paid off on day 45, when the invoice pays |
| Interest in this example | $5,326.20 | $609.47 |
In this example the line costs $4,716.73 less in interest than the 12-month working capital loan, because the money is out for weeks rather than a year. The loan still fits a company whose gap never closes, such as one adding a second crew, because its payment is fixed and planned. A line of credit fits the gap that opens and closes with each invoice.
Fuel, parts and per diem before the check arrives
Wages are only part of what goes out before an operator pays. Running costs land on their own calendar, and the table shows how many of them come due before the operator pays.
| Cost | When it is paid | Before or after the operator pays |
|---|---|---|
| Crew wages | Every other week | Before |
| Fuel for pickups and pumps | At the pump or on the fuel card statement | Before |
| Parts and rebuilds | On the supplier's terms | Before, unless the supplier waits |
| Per diem and lodging for a distant job | During the job | Before |
| Insurance and equipment notes | Monthly | Either |
Not every outfit carries a crew. Nonemployer Statistics for 2024 counted 74 businesses with no paid employees under NAICS 21311, support activities for mining, in Carter County, OK. For an owner working alone, fuel and parts are the whole cost line ahead of the invoice, and a small line of credit can carry them.
Customer concentration and how funders view it
When one operator pays most of a company's bills, that operator's payables calendar is the company's cash calendar. A funding partner can ask how billing splits across customers, how long each relationship has run and what the master service agreement says about terms.
| Customer | Billed in 12 months |
|---|---|
| Operator A | $412,000 |
| Operator B | $138,000 |
| Operator C | $96,000 |
| Operator D | $54,000 |
| Total | $700,000 |
In this example Operator A accounts for 58.9% of $700,000 in billing. A partner looking at that file can set a smaller amount, ask for the aging report by customer, or ask how long Operator A has paid on its terms. A company can show that history in its own statements, and show what the other three customers add. Other posts for service companies and shops in Ardmore, OK are on the Windpoint blog.
