Service businesses sell time and expertise, which makes billing more nuanced than selling a product. Here is how successful freelancers and agencies keep invoicing simple and profitable.
Choose the right billing model
Each model suits a different type of project.
- Hourly: best for open-ended or support work.
- Fixed fee: best for well-scoped deliverables.
- Retainer: best for ongoing, predictable work.
💡
Pro Tip
Request a 30-50% deposit before starting. It filters out unserious clients and funds your work upfront.
Bill from tracked time
Log hours against projects and convert them into invoice line items so nothing goes unbilled.
Use milestones for big projects
Split large projects into deposits and milestone invoices to protect your cash flow.
