Freelancers and agency owners on r/freelance describe a specific financial blind spot: milestone-based contracts where the client has received deliverable value but the invoice hasn't been sent yet — a form of uncollected earned income that distorts their real cash position. MilestoneDebt Log tracks the gap between 'work delivered' and 'invoice sent,' giving freelancers a live 'money you've earned but haven't asked for yet' number that motivates timely invoicing. This is the complement to InvoiceAging Alerter (which tracks post-invoice delays) — covering the pre-invoice gap.
