The smallest group after proposals, and the one growing fastest: five tools whose AI runs the close for client accounting services teams. Double codes bank feeds with confidence-staged categorization, posts accruals and explains variances from $10 a connected client, and its Autoclose agents are an add-on; Xenett runs 50-plus AI checks on QuickBooks Online and Xero files for $7.50 a client; XBert runs 88-plus data-quality checks and plain-English practice queries from $29 per user plus $7 a client; Truewind and Meridian (Pilot's firm-facing platform) close the books end to end at quoted prices.
If what you need is the ledger doing more of the work itself, several tools in the Bookkeeping category — Digits, Kick, Botkeeper, Integra Balance AI — now run an agentic close too, and the Practice Management category has the task side of month-end (Client Hub, Financial Cents). This category is for the review-and-close layer that sits on top of whatever ledger the client uses.
