Questions consultants ask us

Should consultants bill hourly or by project?

Hourly protects you on open-ended scopes; fixed-fee maximizes margin on well-defined ones. Most US consultants use both — Influx Theory supports either per invoice.

How do I invoice for expenses I incurred for the client?

Add them as separate line items tagged as 'reimbursement at cost.' This keeps them out of your gross revenue for tax purposes when you pass them through.

What payment terms are standard for consulting in the US?

Net-30 with mid-engagement billing milestones is most common. For new clients, a 50% deposit upfront protects you against scope creep.
