Overview

Bookkeeping, Accounting & F&A Outsourcing handles the recurring back-office of finance — transaction recording, accounts payable and receivable, monthly close, reconciliations, and increasingly the full outsourced finance function (controller- and CFO-as-a-service). Clients skew to small and mid-sized businesses that lack an in-house finance team.

It is the fastest-growing corner of accounting, propelled by cloud accounting software, automation of data entry, and tech-enabled providers that pair offshore delivery with a software layer. The economics are attractive: monthly retainers, low switching friction once embedded in a client's systems, and high recurring revenue.
