Paperwork is the worst part of working with independent contractors. PayWelly makes it the easiest. PayWelly turns a handshake into a real contract, a payment, and a filed 1099 — one clean flow for U.S. businesses and the independent contractors they work with. Agree on the work, sign in the app, and let PayWelly handle the payment and the year-end tax paperwork. FOR BUSINESSES - Create a per-engagement Independent Contractor Agreement in minutes — hourly or flat-rate by milestone - Break a flat-rate project into milestones, each with its own scope, due date, and amount - Save a card at signing and get charged only when you approve the finished work — no funds held - Approve, and your contractor is paid the same day - W-9 collected up front; Form 1099-NEC filed automatically once a contractor crosses $2,000 for the year - Manage every engagement, location, and team member from one place FOR CONTRACTORS - Every job starts with a clear, signed agreement — you know the scope and the pay before you begin - Get paid the same day the client approves — free by bank transfer, or 3% for a same-day debit-card transfer - Keep 100% of your rate — the business covers the platform fees - Track your year-to-date earnings toward the $2,000 1099-NEC threshold - Take on more than one client, on your own schedule - A signed, timestamped record of every agreement, right in the app HOW PAYMENT WORKS The business saves a card when the contract is signed and is charged only when the work is approved — and that's the moment the contractor gets paid. If the business doesn't respond, the engagement auto-confirms 24 hours after completion. PayWelly absorbs Stripe processing fees. PRICING YOU CAN SEE Businesses pay a $19.99 platform fee per contract plus 15% commission (flat-rate milestone contracts add $4.99 per milestone). Contractors pay nothing to get paid by bank transfer. Every fee is shown before anyone agrees. No subscription. BUILT ON TRUST - Identity verification for every contractor before their first payout - Payments processed by Stripe; card details are tokenized and never stored on our servers - A documented e-signature record for every contract - In-app dispute resolution for completion or payment concerns PRIVACY Location is used only at clock-in for on-site engagements — foreground only, never in the background. Full policy at paywelly.com/legal/privacy. Download PayWelly to send your first contract — or accept your next one.
