Detailed Explanation
Weekly Billing Invoice Guide
Weekly invoicing is common for ongoing contracts, agency work, and embedded consulting roles. It provides frequent payment cycles and keeps both parties aligned on time and costs.
When Weekly Billing Makes Sense
- Long-term contracts with predictable weekly hours
- Agency subcontracting where the agency bills weekly
- High hourly rates where monthly totals are substantial
- Cash flow management -- more frequent payments mean steadier income
