Invoices take minutes, not hours.
Fixed fees billed by progress, hourly work at each person's rate, monthly retainers, reimbursable expenses and purchases with markup, consultant bills passed through, and sales tax where it applies, all on one invoice. For a fixed-fee phase you type the percent complete this period and the amount is computed against the phase fee. The rest fills in from the timesheets and the bills you attached, and the total updates as you go.

Beautiful and simple.
Your client gets one tidy email: the invoice as a clean PDF, with the work log, the expense report with its receipts, and the consultant bills attached behind it, so nobody has to ask what a line means. When the client pays, the payment lands in their history, and QuickBooks gets the invoice and the payment without anyone re-typing them.

A project progress report, in one click.
Every invoice can carry a progress schedule, generated in a click: each fixed-fee phase with its contract fee, what was billed before, what this invoice bills, billed to date and what remains, and the same for hourly services against their budgets. Every row ties, so the client sees where the project stands, not just what this month costs.
