Days to get paid: the hidden signal to watch

2026-07-11 · By Lubin Danilo, founder of Lubin Investment

The cash conversion cycle measures how long it takes a company to turn a sale into cash actually sitting in its account. Some companies collect payment before they even deliver, others wait months after billing. This detail, often overlooked, says a lot about a company's negotiating power and how much cash it must tie up just to keep running.

Selling is not the same as getting paid

A company can book a sale in its accounts well before it receives the corresponding cash. In between, there is a lag: the time it takes the customer to pay the invoice. This lag has a name in my criteria: the cash conversion cycle (often called CCC, or DSO for the customer side, days sales outstanding). The shorter it is, the less a company must front out of its own pocket between the moment it sells and the moment it actually gets paid.

This is not a minor accounting detail. A company that must fund months of waiting before getting paid ties up cash that is not working anywhere else, and it takes a risk if a customer is late or never pays. A company that collects fast, or even before delivering, instead has free money to put to work in the meantime.

The most favorable extreme: getting paid before you pay

Winmark, the franchise I analyzed in a separate article, shows a negative cash conversion cycle: minus 73 days. In practice, it collects money (entry fees, royalties) before it even has to settle its own suppliers. This is what is called a float model, a term borrowed from insurers: the company holds other people's money to put to work before having to return it or spend it. Delta Air Lines, which I have already covered, shares something with this: it collects ticket money well before the plane flies, with a negative collection delay of 14 days.

The other extreme: waiting months to get paid

At the opposite end, some companies wait a long time. I already showed the example of Paychex, which handles payroll for small businesses: its customer collection delay reaches 71 days, over two months. That is not dramatic by itself if the company has a solid balance sheet, but it means it permanently funds the equivalent of several weeks of revenue while waiting to be paid. Even more extreme, KLA Corporation, which sells semiconductor manufacturing equipment to a small number of very large customers, shows a 275-day delay, almost nine months, due to complex sales cycles on expensive industrial equipment.

Why some sectors escape this criterion

For banks, this criterion simply becomes impossible to compute with my usual method. A bank does not sell a product on credit to a customer like an industrial company: its business is precisely to lend and borrow money, so the classic notion of "time before getting paid for a sale" does not apply the same way. That is why you will often see "not calculable" on this criterion for financial stocks in my screener: it is not a negative signal, just a criterion that does not apply to this type of business.

How I use this criterion

A short or negative collection delay is a real positive in my framework: it reflects strong negotiating power over customers, or a business model that collects upfront. A long delay is not disqualifying by itself, but I always look at it relative to the sector: a maker of complex industrial equipment will almost always have a longer delay than a subscription software company, and that is not abnormal. What matters is comparing a company to its direct peers, not to the whole market.

Key takeaways

The collection delay measures the time between a sale and cash actually available in the company's account
Winmark collects 73 days before paying its own bills (float model), Delta collects ticket money 14 days before the flight
Conversely, Paychex waits 71 days and KLA Corporation 275 days to get paid by their customers
For banks, this criterion is usually not calculable: their business (lending and borrowing) does not follow the same logic
A short delay is a real advantage, a long delay should be compared to peers in the same sector, not the whole market

FAQ

What is days sales outstanding (DSO)?

The number of days it takes a company to turn a billed sale into cash actually available in its account. The shorter it is, the less cash a company ties up while waiting to be paid.

What is a negative cash conversion cycle?

It means the company collects money from customers before it even pays its own suppliers. Winmark (minus 73 days) and Delta Air Lines (minus 14 days) are real examples in my screener.

Why is this criterion often not calculable for banks?

A bank lends and borrows money, it does not sell a product on credit like an industrial company. The classic notion of customer payment delay does not apply the same way to its business.

Does a long collection delay automatically disqualify a stock?

No. Some sectors (complex industrial equipment, giant contracts) structurally have a longer delay. I always compare a company to its direct peers rather than to the whole market.

About the author

Written by Lubin Danilo, founder of Lubin Investment. A self-taught individual investor, I find fundamental analysis fascinating, and it has delivered excellent results. For three years now, my performance has beaten the S&P 500. But analyzing every stock took too much time: sites with incomplete data, calculation methods and criteria never aligned with mine. And spotting the best stocks was just as time-consuming, even with my own well-defined checklist. So I put my software development background to work to build this software, base my investment strategy on its results, and share it with people who share the same passion as me. It judges a company's quality and its price separately, using criteria drawn from the financial literature (Warren Buffett, Michael Mauboussin, Aswath Damodaran).
