Tâches.ma: Zero-Trust Escrow Payments & Field Ops Automation in Dirhams
Why Standard Cloud Stacks and Legacy Tools Failed
Hiring Moroccan contractors (developers, plumbers, electricians) relied on informal WhatsApp groups where clients feared upfront fraud and workers feared non-payment. International platforms (Upwork, Fiverr) charge 20% fees and pay in foreign currencies with heavy wire transfer fees back to Moroccan bank accounts.
Custom Low-Latency Architecture & In-Country Execution
Vext engineered Tâches.ma with an immutable escrow ledger in Moroccan Dirhams (MAD). Project funds are held securely upon agreement, milestone proofs are verified, and emergency repair calls are automatically dispatched via a WhatsApp/voice finite state machine.
| Metric | Legacy / External Stack | Vext Sovereign System | Measured Gain |
|---|---|---|---|
| Payment Dispute Rate | 34% (Informal WhatsApp deals) | 0.4% (Escrow Milestone Ledger) | 98.8% Dispute Drop |
| Emergency Dispatch Latency | 4 hours (Manual phone search) | 4 minutes (Automated Loop) | 98.3% Faster Dispatch |
| Platform Commission Fees | 20% Upwork cut + 4% FX | Transparent low local MAD fee | -75% Fee Savings |
Key Engineering Deliverables
- Immutable escrow financial ledger with multi-party milestone release
- PostgreSQL Row-Level Security (RLS) guaranteeing strict account data isolation
- Conversational WhatsApp bot triaging urgent plumbing/electrical callouts
- Direct integration with Moroccan domestic bank transfer APIs
Measured Production Impact
- 14,000+ emergency field interventions dispatched with zero lost tickets
- Over 8.5 Million MAD protected in zero-loss escrow transactions
- 100% local compliance with Bank Al-Maghrib payment transparency guidelines
Architectural Context & Deployment Narrative
In Morocco, the informal service economy is held back by a fundamental trust deficit: clients worry that paying deposits upfront leads to unfinished work, while technicians worry that completing difficult jobs ends in delayed payment or refusal. Vext designed Tâches.ma to create institutional trust out of software. By introducing an escrow ledger in Dirhams (MAD), funds are locked before work begins and released upon client sign-off. When an urgent home repair strikes, an automated WhatsApp bot triages the problem, calculates transparent pricing, and dispatches the nearest certified technician in minutes.
