Intuit , PayPal and Square already know how much money millions of small businesses are bringing in each day. Now these tech firms are stepping up efforts to mine that data to get into the lending business.

In the latest move, Intuit Inc., the maker of TurboTax, is expected to announce Thursday that it is teaming up with online lender OnDeck Capital Inc. to create a $100 million fund to provide loans to users of its QuickBooks accounting software.

“The bottom line is that small businesses need financing,” said Intuit executive vice president Dan Wernikoff. “They are not getting it at the same levels that large businesses are.”

Small business lending remains well below prerecession levels. Banks held $599 billion in small loans to businesses at the end of the second quarter, according to the Federal Deposit Insurance Corp., down nearly 16% from a peak of $711 billion in 2008. By contrast, loans to larger companies increased 35% during that time.

Intuit isn’t the only one seeking to fill the gap. Payments companies PayPal Inc. and Square Inc. are using transaction data to provide financing to their small business customers. United Parcel Service Inc. this summer launched a partnership with online lender Kabbage Inc.
