As answered by people managing MileStage and Opalstack.
MileStage's answer
I'm a UI/UX designer who got burned too many times by late payments and scope creep. I wanted a tool that enforced boundaries for me so I didn't have to be the bad guy with clients. Couldn't find one that was simple enough, so I built it myself using AI tools despite having no coding background.
MileStage's answer
Stage-based payment enforcement. Unlike invoicing tools where you bill after the work is done, MileStage locks each project stage until the previous one is paid. The system enforces payment boundaries automatically - no awkward conversations, no scope creep. Plus zero transaction fees since payments go directly to your Stripe account.
MileStage's answer
Freelancers who work in milestones - designers, developers, content creators, photographers, consultants. Anyone who delivers work in phases and has dealt with clients delaying payments or quietly expanding scope. Especially appeals to solo freelancers who want something dead simple without the complexity of all-in-one platforms.
MileStage's answer
React and TypeScript for the frontend, Supabase for database and authentication, Stripe Connect for payments, Vercel for hosting, and Resend for email notifications.
MileStage's answer
We're early stage and focused on individual freelancers rather than big names. Currently onboarding beta users and gathering feedback to refine the product before scaling up.
MileStage's answer
Most freelance tools try to do everything - contracts, invoicing, scheduling, CRM, time tracking. They're powerful but overwhelming, and most freelancers end up using 20% of the features while paying for 100%. MileStage does one thing well: stage-based payment tracking with automatic enforcement. Client can't move forward until they pay. No manual chasing, no awkward follow-ups.
The other big difference is cost. Some platforms take 2-3% of every transaction. MileStage charges a flat monthly fee with zero transaction fees - payments go straight to your Stripe account. If you're billing $5k+ per month, that savings adds up fast. If you want an all-in-one business suite, MileStage isn't for you. But if you just want to stop doing free work and get paid on time without managing another complicated tool, that's exactly what it's built for.
