What to include
What goes on a Consulting invoice?
⏱️
Hourly rate or project fee
For time-based work, list the number of hours and hourly rate separately. For deliverable-based work, list each deliverable at a fixed project fee. Mixed projects can have both.
📝
Deliverables and outputs
List every tangible output - reports, frameworks, presentations, strategies. Clients need to see what they received in exchange for the fee.
📋
Reference to your agreement
Include a note referencing the signed consulting agreement or SOW. This protects you legally and reminds the client that the work is governed by a contract.
💳
Payment terms and late fees
State your net payment terms (Net 14 or Net 30) and include your late payment fee (e.g., 1.5% per month). Most clients pay faster when late fees are visible.
Pro tips
Consulting invoicing tips that get you paid faster
Invoice weekly or bi-weekly for ongoing retainer work rather than monthly - it improves cash flow and keeps the client engaged.
Include a reference to your signed consulting agreement or SOW on every invoice to create a paper trail.
Separate "advisory time" (calls, meetings) from "deliverable work" (documents, reports) as different line items.
For project-based consulting, invoice 50% upfront before starting and 50% on delivery.
State your late payment fee on every invoice - it dramatically reduces slow payers.
FAQs
Common questions about consulting invoices
What should a consulting invoice include?
A consulting invoice should list hours worked and hourly rate (or fixed project fee), deliverables completed, reference to the signed agreement or SOW, payment terms, and any applicable late fees.
How do consultants typically bill clients?
Consultants bill by the hour, by the day (day rate), by the project, or on a monthly retainer. Retainers work best for ongoing advisory relationships. Fixed project fees work best when scope is clearly defined upfront.
What payment terms should consultants use?
Net 14 is most common for independent consultants. Large enterprises may require Net 30 or Net 45. Smaller clients and retainers often pay on receipt. Always state your preferred terms on the invoice.
How do I invoice for a consulting retainer?
Create a recurring monthly invoice for the retainer amount. Track hours used against the retainer and include a usage summary. Bill any hours above the retainer cap at your standard hourly rate as a separate line item.
