What to Include on a Sole Proprietor Invoice

Common Billing Models for Sole Proprietors
Sole proprietors typically bill using one or more simple models depending on the type of work.
1) Hourly
Quantity = hours, rate = hourly rate. Best for ongoing or variable work.
2) Fixed project fee
One line item for a defined scope. Best when deliverables are clear.
3) Retainer
Monthly fee for a defined amount of work or access. Include a service period.
4) Expenses
Itemize reimbursable expenses separately (materials, mileage, tools, shipping).
Your invoice can combine models (e.g., fixed fee + hourly extras). The key is clear line items and a simple total.
