One way to track the rise of tech — check the expense reports

Tech disruption is increasingly showing up on expense reports.

For the first time, Lyft has become one of the Top 10 most frequently expensed U.S. business costs this quarter, according to new data from online travel and expense software company Certify. At No. 6, Lyft joins Uber and Amazon, which have been climbing the ranks since first appearing in the Top 10 three years ago. Both Uber and Amazon’s numbers include their food delivery businesses.

Lyft makes now up 3 percent of all U.S. business expenses, while Uber represents 11 percent and Amazon 4 percent. That’s up from next to nothing a few years ago.

This growth in usage reflects changing corporate travel trends, and has enabled tech companies to take an increasingly large bite out of the world’s $1.4 trillion business travel industry.

Naturally, the ascent of these tech companies has pushed other companies out.

Uber has grown to 73 percent of all ride-hail expenses (Uber Eats is not included here), while Lyft is 20 percent and taxis represent 7 percent (this market share doesn’t include other rides-share players, so the true percentage would be a bit smaller). Just four years ago, taxi rides made up 74 percent — about the same as Uber now — of all ride-hailing receipts. The average Uber or Lyft expense is around $25.

Other related industries, like rental cars, have also felt competition from ride-hailing apps.

Amazon’s rise on expense reports hasn’t pushed out its biggest competitor, Walmart, which has managed to maintain its place for the most part on the Top 10. The average Amazon expense, however is $110, nearly double the $56 spent at Walmart. And what are people buying from Amazon? Everything from business supplies to cloud computing to food delivery.

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple of big issues with relying on ads and subscriptions to keep the lights on:

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. And we can’t do that if we have a paywall.

So even though advertising is still our biggest source of revenue, we also seek grants and reader support. (And no matter how our work is funded, we have strict guidelines on editorial independence.)

If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today? Any amount helps.
