Automated 3PL & parcel invoice audit engine for e-commerce brands.
TARE (Tare Audit & Reconciliation Engine) is a turnkey B2B logistics SaaS engineered to audit 3PL warehouse invoices and parcel shipping ledgers (FedEx, UPS, DHL). It automatically flags dimensional weight (DIM) divisor variances, SLA transit delay refunds, Pick & Pack fee creep, and duplicate tracking numbers. I built the entire core engine, automated test suite, and web app, but lack the bandwidth to run outbound sales and marketing. Looking for a fast sale to hand over the full codebase and project. Key Features & Stack: Built with modern Node.js 22 + TypeScript (Native, Zero External Dependencies). 31 Automated Tests (npm test) validating dispute formulas, holiday SLAs, and carrier rate reconciliation (100% passing). Zero-Credential Architecture: CSV ledgers are evaluated securely in transient memory without requiring client FedEx/UPS portal passwords. Turnkey Frontend: Institutional fintech theme, responsive mobile navigation, interactive ROI margin calculators, and automated dispute packet generation. Full Auth & Billing: OTP email verification, password reset lifecycle, and mock Stripe/Crypto subscription workflows. Minimal Operating Cost: Hosted live on Render ($7/month server cost, 95%+ gross margins). Live Demo URL: https://tare-k37o.onrender.com What is included in the sale: 1. Complete GitHub source code repository (full commercial IP ownership). 2. All 31 automated test suites and validation scripts. 3. Production Render deployment setup. 4. Sample invoice datasets and dispute claim templates. 5. 14 days of handover and codebase walk-through support. Asking Price: $900 OBO (Open to reasonable offers for a quick 24-48h close). Payment accepted via Crypto (USDT) or direct card transfer.
Next step: <p>1. Outbound Sales: Launch targeted cold email or LinkedIn outreach to Shopify brands spending $20k+/mo on FedEx/UPS shipping.</p><p>2. Agency Add-On: E-commerce or 3PL agencies can use TARE as a white-label value-add service for their existing clients.</p><p>3. Turnkey Monetization: Simply plug in your Stripe account or crypto wallet to collect recurring $39/mo and $79/mo subscriptions.</p>
