Pipeline Gate Tracker

Bilko Pipeline — 8-Gate Tracker

Overview

This document tracks Bilko's progress through the 8-gate pipeline from concept to CEO approval.

Project: Bilko (Balkan Accounting SaaS) Project ID: bbd77cc0 Company: SnowIT Internal R&D Created: 2026-02-19

Gate Definitions

  1. Market Research — TAM/SAM/SOM analysis, customer pain points
  2. Competitive Analysis — Competitor landscape, differentiation strategy
  3. Tech Stack Decision — Frontend, backend, database, hosting choices
  4. Product Requirements — PRD with features, user stories, acceptance criteria
  5. Database Schema — Full schema design validated against PRD
  6. UI/UX Design — Wireframes, mockups, design system
  7. Regulatory Compliance — Legal research (Serbia, BiH, Croatia accounting laws)
  8. CEO Approval — Final go/no-go decision from Alem

  • ✅ Resource estimate (8-10 weeks MVP, €2K bootstrap)

Gate 5: Database Schema — PASS

  • ✅ All PRD features covered by schema (15 models)
  • ✅ No phantom features in schema not in PRD
  • ✅ Multi-currency support validated (Currency + ExchangeRate models)

  • ⚠️ 2 MEDIUM-confidence items (BiH e-invoicing pending, Serbia digital cert) — NOT blocking

Gate 8: CEO Approval — PASS

Approved by Alem on 2026-02-20

✅ CODE UNFROZEN — Backend development started

Deliverables:

  • ✅ Backend foundation implemented (Express + TypeScript)
  • ✅ Authentication system (JWT + bcrypt, 4 endpoints)
  • ✅ Middleware stack (helmet, cors, rate-limit, auth, validation, error-handler)
  • ✅ Database exports (@bilko/database package)
  • ✅ Project structure ready for remaining endpoints

Backend Status (2026-02-20):

  • ✅ 4/50 API endpoints complete (auth: register, login, refresh, logout)
  • ⏳ 46/50 endpoints pending (invoices, expenses, contacts, etc.)
  • ✅ All middleware and utilities implemented
  • ✅ Route aggregator ready for expansion

Next Steps:

  1. Implement remaining 46 API endpoints (invoices, expenses, contacts, accounts, transactions, reports, banking)
  2. Create Zod validators for all endpoints
  3. Add integration tests for auth flow
  4. Connect frontend to real backend (replace mock data)
  5. Beta testing with 5 SMBs + 3 accountants

Status: DEVELOPMENT IN PROGRESS

All 8 gates PASSED — Project approved and active

Decision Log
