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

Gate Validation Summary (2026-02-20)

Validation performed by: John (AI Director) Full report: docs/VALIDATION-REPORT.md

Gate 4: Product Requirements — PASS

  • ✅ All features mapped to user stories
  • ✅ Acceptance criteria defined
  • ✅ Technical feasibility confirmed
  • ✅ 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)
  • ✅ Double-entry bookkeeping validated (Transaction.debitAccountId + creditAccountId)
  • ✅ Audit trail meets compliance needs (LoggedAction append-only)

Gate 6: UI/UX Design — PASS

  • ✅ All pages match wireframes (10 pages implemented)
  • ✅ Design system consistent (colors, typography, spacing verified)
  • ✅ Responsive design validated (mobile-first Tailwind)
  • ✅ Accessibility compliance (shadcn/ui Radix primitives)
  • ✅ User flows tested (invoice wizard, expense entry, reports)

Gate 7: Regulatory Compliance — PASS

  • ✅ Serbia — SEF e-invoicing, 20% PDV, Kontni Okvir Chart of Accounts
  • ✅ BiH — 17% PDV, IFRS/RS accounting, e-invoicing draft law monitored
  • ✅ Croatia — eRačun mandatory 2026, 25% VAT, RRiF Chart of Accounts
  • ✅ No LOW-confidence MVP blockers
  • ⚠️ 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

Date Gate Decision Rationale
2026-02-19 1 PASS TAM €50-150M validated, clear pain points identified
2026-02-19 2 PASS 3 competitors analyzed (Fiken, QuickBooks, local solutions), differentiation clear
2026-02-19 3 PASS Tech stack chosen — Next.js + Express + PostgreSQL (proven, scalable)
2026-02-20 4 PASS PRD complete — all features mapped to schema, acceptance criteria defined
2026-02-20 5 PASS Schema validated — 15 models cover all PRD features, double-entry enforced, NUMERIC(19,4) for money
2026-02-20 6 PASS Design validated — 10 pages implemented, design system consistent, responsive
2026-02-20 7 PASS Regulatory validated — All 3 countries researched, no blocking issues, 2 MEDIUM items not MVP blockers
2026-02-20 8 PASS CEO approval granted — Backend foundation implemented, 4/50 endpoints live, development started

Notes

  • Backend development started (2026-02-20) — Authentication system complete, 46 endpoints remaining
  • Frontend is prototype — Still using mock data. Backend connection pending full API implementation.
  • All 8 gates passed — Project approved and active as of 2026-02-20
  • Gate 8 deliverables:
    • /apps/api/src/ — 18 source files created (middleware, routes, utils, validators)
    • /packages/database/src/index.ts — Prisma exports added
    • JWT authentication with access + refresh tokens
    • Rate limiting (5 req/min auth, 100 req/min general)
    • Organization-scoped multi-tenancy middleware ready
    • Error handling with consistent API format

Production Infrastructure Gates

These gates are outside the 8-gate pipeline but block production readiness.

Gate Name Trigger Status Notes
HA-1 REGIONAL HA Upgrade Before first paying-tenant transactions row write PENDING See infrastructure/gcp/runbooks/bilko-db-ha-upgrade.md

HA UPGRADE GATE

REGIONAL HA must be applied (via online tier upgrade) before first paying-tenant transactions row write.

  • Trigger: First signed/paying beta tenant onboards (Stripe subscription created OR first transactions table INSERT for a real-money transaction)
  • Estimated cost impact: $45/mj (ZONAL db-custom-1-3840) → $90/mj (REGIONAL db-custom-1-3840 — standby replica added in second zone, same europe-north1 region)
  • Execution: gcloud sql instances patch bilko-db --availability-type=REGIONAL --project=tribal-sign-487920-k0 (online, zero downtime for dedicated-core tier per GCP docs)
  • Full runbook: infrastructure/gcp/runbooks/bilko-db-ha-upgrade.md
  • Approval required: CEO + FlowForge on-call confirmation

ZONAL is acceptable for pre-revenue testing. Financial data write without HA = risk accepted explicitly by CEO (Q4 approval 2026-05-13). Revision recorded in MC #100534.
