Always invoice for your time
Track hours carefully. If billing hourly, use quantity = hours and price = hourly rate. This creates an automatic total.
Add a consulting reference number
For large clients with purchase order systems, add the PO number in your Notes field to speed up payment processing.
Specify deliverables in line items
"Strategic growth plan — 12-page document" is better than just "Consulting." Specificity reduces invoice disputes.
Use Net 30 for corporate clients
Large businesses often have 30-day payment cycles. Set your due date accordingly and follow up on day 31 if unpaid.
Frequently Asked Questions
How do consultants typically invoice?
Most consultants invoice either hourly (quantity = hours, price = rate) or on a project/retainer basis (fixed fee per line item). Both work well with our invoice generator.
Should I invoice before or after the consulting engagement?
For project work: invoice 50% upfront, 50% on completion. For ongoing retainers: invoice monthly, in advance. For hourly work: invoice at end of month or end of project.
How do I handle expenses on a consulting invoice?
Add a separate line item for expenses (travel, accommodation, software). Label it clearly — e.g., 'Expenses — travel to client site: train + hotel.'
