Turn off the columns you don't need.
Billing a fixed-fee project shouldn't mean showing "Qty 1 × Unit price $5,000." Other invoicing tools force quantity and unit price onto every line whether they make sense or not. Invoice100 lets you switch off any column and rename the ones you keep.
Toggle quantity, unit, unit price and any other column on or off per invoice
Rename column headers to match how you actually bill: hours, days, sessions, milestones
Set default labels once, override them on any single invoice
