Sample line items for consultants

The line items below are the shapes most consultants use. Copy them, adjust to your scope, fold them into the invoice format your accounting tool spits out.

Description	Qty	Rate
Strategy engagement - Q2 advisory retainer	1	$4,500 / month
Stakeholder interviews (8 × 45 min)	8	$0 - included in retainer
Final memo + recommendations deck	1	$0 - included
Extra board presentation (out of scope)	1	$1,800 flat

Recommended payment terms

Retainer: invoice on the 1st, Net 7. Project work: 50% deposit, balance Net 14 from delivery. Hourly: Net 14, weekly billing if the engagement is intense.

The gotcha most consultants miss

Consulting clients pay slowly when they can't tell what they got. Always attach a one-page deliverable summary to the invoice (or note in the line item description: 'Q2 retainer covered ... included memo dated ...'). Make the value scannable.

Typical rates for consultants in 2026

Independent management consultants charge $150–$500/hour depending on specialty. Retainer-style engagements at the executive-advisor level run $3,000–$10,000/month for a few hours of weekly time.
