Consultant-specific invoice tips
Always include deliverables in the description
Don't just write "consulting services". Write "3 strategy workshops + written GTM playbook + 2 rounds of review". This prevents scope disputes.
Separate your time from expenses
Bill professional fees and reimbursable expenses (travel, tools) as separate line items. Clients appreciate the clarity and it's cleaner for their bookkeeping.
Retainer invoices should be sent on the 1st
Send monthly retainer invoices on the 1st of each month — before you do the work. Never work a full month and invoice at the end.
Include a "scope exclusions" note
"This invoice covers strategy advisory only. Implementation, recruitment, and ongoing execution are billed separately." Prevents "I thought this included X" conversations.
