Integrations for contract-to-cash and reconciliation

Lucius syncs operational data from billing, banking, and payroll systems so settlement, cash application, and reporting run from one ledger.

Stripe integration

Stripe is where revenue is captured and settled for most modern revenue businesses. To run contract-to-cash and reconciliation correctly, Lucius needs every Stripe event tied back to its invoice, contract, and settlement.

Mercury integration

Mercury is the operating bank for most modern startups. Reliable, real-time bank sync is the foundation of reconciliation and cash reporting.

Brex integration

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.

Justworks integration

Justworks is the payroll and PEO layer for many US startups. Lucius needs pay run data to keep salaries, payroll taxes, and benefits accurate by function and COA category — and to reconcile payroll outflows against bank settlement.

Stripe Billing integration

Stripe Billing handles subscription mechanics and payment collection. Lucius turns those billing events into maintained financial state — contracts, receivables, deferred revenue, and recognition — so subscription revenue is correct on the ledger, not just collected.

QuickBooks integration

Most growing companies start on QuickBooks. Lucius imports your QuickBooks data so you can migrate to a stateful system of record without losing history or rebuilding your books from scratch.

Xero integration

Companies on Xero that have outgrown month-end bookkeeping can migrate to Lucius without losing history. Lucius imports your Xero data and validates opening balances so the stateful ledger starts from a verified position.

Plaid integration

Plaid is how Lucius connects to most US banks. Reliable bank connectivity is the foundation of reconciliation and cash reporting — every deposit and debit needs to land in Lucius to be matched against invoices, bills, and settlement.

Gmail integration

Vendor bills and receipts arrive in email. Lucius parses invoices from Gmail so payables enter the system automatically — matched to vendors and the right accounts — instead of being manually keyed or lost in an inbox.

Stripe Revenue Recognition integration

Stripe Revenue Recognition reports revenue inside Stripe, but it lives apart from your ledger and contracts. Lucius derives recognition from contract terms and posts deferred and recognised revenue directly to the stateful ledger, so revenue, AR, and cash stay connected in one system of record rather than split across Stripe and accounting.
