A professional invoice for consultants

Consulting invoices should read as cleanly as your work. List advisory hours, fixed-scope deliverables, or a monthly retainer as separate line items, apply your tax rate, and add payment terms so clients know exactly when payment is due. Plainvo keeps the layout crisp and the math automatic.

Everything happens in your browser — your client relationships and rates never touch a server. Save your business details once, reuse them on every invoice, and export a PDF that looks like it came from a firm twice your size.

Built for the way consultants bill
