In strategic partnership with HSB & Partners, a Franco-Senegalese accounting firm operating in Paris and Ngaparou, we engineered a full digital transformation powered by generative AI and agentic workflows. The platform connects HSB’s accounting software to autonomous AI agents that generate validated entries, manage document pipelines, and deliver real-time financial analysis—giving both accountants and clients unprecedented transparency.

HSB needed to reduce manual accounting workload, eliminate document-chasing friction, and provide real-time client visibility—without compromising professional standards, auditability, or multi-software compatibility.

Diakitech led architecture, full-stack development, AI agent orchestration, data/analytics, integration middleware, and compliance-driven security.

✓ Automated Accounting Entries with validation ✓ Intelligent Document Management: reminders, processing, follow-ups ✓ Smart Document Workflows: OCR extraction, classification, sync ✓ Real-Time Processing Dashboard with anomaly detection ✓ Financial Analysis & Reporting: trends, cash-flow, custom insights ✓ Client Transparency Portal: live status & processing metrics ✓ HSB Virtual Office: centralized AI supervision + team productivity ✓ Automated Reminders for deadlines and filings ✓ Multi-Software Integration: Sage, Cegid, QuadraExpert, ACD connectors ✓ Compliance & Security aligned with GDPR and French/OHADA standards

➝ Frontend: Next.js 14 (App Router) + TypeScript, Tailwind CSS, Framer Motion ➝ Backend: Supabase (PostgreSQL + Auth + Storage + Realtime), Node.js services ➝ AI/ML Stack: Python services, LangChain, Claude Sonnet 4 + GPT-4 agents ➝ Document Processing: OCR, PyPDF2, ML models for French accounting ➝ Accounting Integration: REST APIs + webhooks for Sage, Cegid, QuadraExpert ➝ State Management: TanStack Query, Zustand, React Hook Form + Zod validation ➝ Real-Time Sync: Supabase Realtime, WebSockets, bidirectional data flow ➝ Financial Analytics: Python (Pandas, NumPy), forecasting models, visualization ➝ Component Library: shadcn/ui, Radix primitives, WCAG 2.1 AA compliance ➝ Security: RLS, JWT auth, AES-256 encryption, rate limiting

HSB now operates at the forefront of AI-powered expertise comptable. Autonomous agents handle repetitive document and entry workflows while accountants keep full oversight through real-time dashboards. Clients gain continuous visibility into processing status and insights, enabling a more proactive advisory model across both Paris and Senegal operations.

We built an intelligent middleware that cleanly separates AI orchestration from accounting-software integration. This keeps HSB in control, preserves compliance, and allows automation to scale safely—modernizing the firm’s operating model without disrupting trusted tools.
