Frequently Asked Questions
MicrocosmWorks implemented a milestone-based escrow system where client funds are held in a Stripe Connect custodial account and released only when the client confirms deliverable completion or after a 72-hour auto-approval window. Disputes trigger a mediation workflow with evidence submission from both parties before any funds move.
MicrocosmWorks built a geospatial matching engine using PostGIS that calculates worker proximity, skill relevance, and availability in real time. Workers receive push notifications for nearby jobs ranked by a composite score of distance, pay rate, and historical completion success, with matches surfaced within seconds of job posting.
MicrocosmWorks integrated identity verification through Stripe Identity for document checks, combined with phone verification and behavioral analysis. The platform tracks completion rates, dispute frequency, and review patterns to detect and flag suspicious accounts before they can harm legitimate users.
MicrocosmWorks integrated automated 1099-NEC generation using the Stripe Connect tax reporting API, which tracks earnings by state and generates the required forms at year-end. Workers can download their tax summaries at any time, and the platform provides jurisdiction-specific withholding guidance.
MicrocosmWorks builds gig marketplace platforms at rates of $20-$45/hr, with a full-featured MVP including escrow payments, geospatial matching, chat, and reviews typically requiring 700-1000 development hours. The Stripe Connect integration alone usually accounts for 100-150 hours due to compliance and regulatory requirements.
