Active clients

Active clients are the clients who spent money on Upwork in the trailing twelve months, counted as of the end of each quarter and reported by Upwork Inc. as a key business metric alongside gross services volume.

Upwork Inc. defines an active client as a client that has had spend on the platform in the twelve months ending on the reporting date, and states the count in every quarterly earnings release and in the Key Financial and Operational Metrics table of its Form 10-Q and Form 10-K. It is a point-in-time figure, not a flow: a quarter's number is the size of the paying client base on the last day of that quarter. It is not a GAAP measure and is not audited, though it is reported in filings that are. Because the window is a year, a client who stops spending drops out of the count twelve months after their last payment, so the series moves slowly and a change in it reflects hiring decisions made well before.

Read with gross services volume it explains where volume comes from. GSV divided by active clients is GSV per active client, the average twelve-month spend; rising spend per client with a falling client count means the marketplace is concentrating on fewer, larger buyers, and the Pulse page shows which of the two is moving in any quarter.

The count includes every kind of client, from a single job to an Enterprise programme, and is not split by whether they hired freelancers or agencies. Upwork does not publish a count of active freelancers or agencies at all.
