Fixed fees, hours and expenses
Consulting invoicing software
Consulting invoicing software for independent consultants and small firms. A fixed-fee milestone, the hours logged on an engagement and the flight you rebill all reach one invoice on net 30 terms, and corporate clients pay by ACH.
A short tour of the screens this page describes. It is filmed with our demo pest control company, and every trade runs on the same screens.

Example with sample data
Milestones from the proposal
Send the proposal as an estimate the sponsor signs, with a deposit if you want one up front. Each milestone is then billed separately on the engagement.
Estimates and e-signaturesHours on top of the fee
Work outside the fixed fee is logged as billable time. Invoice the engagement and those hours show up as lines, ready to trim before the bill goes out.
Time trackingTravel and expenses rebilled
Flights, hotels and research subscriptions go on the engagement as expenses, so the rebill line matches what you paid and nothing is missed at month end.
Job expensesNet terms and reminders
Set net 30 as your default, and an open invoice gets reminders at 3, 7 and 14 days after it falls due. Accounts payable gets a copy as a billing contact.
