BILLING & INVOICING

Generate invoices from tracked work

Approved hours and expenses, out the door cleanly.

Octayne turns approved hours and expenses into clean invoices without the month-end scramble. Line items pull the right rate per person, expenses pass through correctly, and once an invoice is sent, it’s locked — no retroactive edits that break your audit trail. QuickBooks sync keeps the ledger in step.

GENERATE FROM ACTUALS

Invoices built on approved hours

Pull billable time entries by person and project into an invoice with a click. Expenses attach with the right passthrough markup, and adjustments are tracked separately for full transparency.

LETTER-LOCKED

Send once, audit forever

Once an invoice is issued, it’s letter-locked. Further edits create adjustments with a reason — so the invoice you sent is always the invoice of record.

RECEIVABLES & QUICKBOOKS

Cash flow visibility, ledger in sync

Invoice status — draft, sent, paid, overdue — is tracked in one place. QuickBooks integration keeps your ledger and AR aging aligned without double entry.

Send invoices that close cleanly
