Key business metrics are the operating statistics Upwork Inc. reports beside its financial statements to describe the marketplace, chiefly gross services volume, active clients and GSV per active client, none of them GAAP or audited.
Upwork Inc. presents them in a table headed Key Financial and Operational Metrics in every earnings release and in the Management's Discussion and Analysis section of the Form 10-Q and 10-K, next to marketplace revenue and adjusted EBITDA. Gross services volume is the money clients paid through the platform in the period; active clients is the count of clients with spend in the trailing twelve months; GSV per active client divides the first by the second. Upwork defines each in the filing, explains why it believes the metric is useful to investors, and warns that its definitions may differ from other companies' and may change.
The metrics are the only public view of the marketplace's size. The audited income statement records Upwork's fees, a fraction of the money moving through the platform; the key business metrics record the whole flow and the paying client base behind it. They are, however, management statistics: no auditor opines on them, the definitions are Upwork's, and the recasting of the Marketplace and Enterprise split from the 2023 annual report shows that a series can be redrawn.
They are distinct from non-GAAP measures such as adjusted EBITDA, which are reworked accounting figures with a reconciliation. A key business metric has no GAAP counterpart to reconcile to, which is also why none of them appears in XBRL. Upwork reports no supply-side metric at all: the number of freelancers, agencies or completed contracts is not among them.
How Upwork Insights uses it
For Q3 2026 the three metrics were GSV of $914.1M, down 10.1% year on year, 717,000 active clients and $5.4K per active client. The Pulse page charts all three every quarter since the IPO, and the index supplies the supply-side counts Upwork does not: 28,921 agencies and 11,749 freelancers as of Oct 31, 2026.
