Integrations
Connect every system that touches your money
Lucius syncs billing, banking, payroll, and payments into one stateful ledger — so settlement, cash application, and reporting run from a single source of truth.
Banking & Cards
Bank connectivity, card spend, and continuous reconciliation
Mercury

Brex
By Lucius
Brex card activity is a significant share of operating spend for many startups. Tying card transactions to vendors and the correct accounts in real time keeps the ledger accurate.

Pay runs, taxes, and benefits by function
