Matter billing and clean books for your firm
Bill by matter, run retainers as recurring invoices, and keep client statements and financial reports tidy — on a self-hosted ledger you fully control.

Built for how law firms actually run the books
Billing and tracking profitability per matter
Tag invoices and costs to a cost center and project per matter, then read the result in dimension reports.
Retainers billed manually every month
Run retainers as recurring invoices that generate themselves on schedule with recalculated taxes.
Clients asking where their balance stands
Hold each client as a customer with a derived statement of invoices minus payments.
Write-offs and fee adjustments after the fact
Issue credit notes against an invoice so the client balance and the ledger both stay correct.
