1. Executive Summary

Project Overview: Bilko is a cloud SaaS accounting platform for Balkan SMBs — the first modern, cloud-native tool purpose-built for Serbian, Bosnian, and Croatian small businesses with full local tax compliance, native language support, and affordable pricing. Phase 1 targets Serbia (300K+ active SMBs) where e-invoicing via SEF has been mandatory since 2023.{{EXECUTIVE_SUMMARY_PARAGRAPH}}

Business Problem: 348,000+ Balkan SMBs have no affordable, modern, cloud-native accounting tool with full local regulatory compliance — they are forced to choose between over-engineered ERP software (Pantheon, Minimax at €150+/month), global tools with no Balkan compliance (QuickBooks/Xero), or manual spreadsheets that violate SEF e-invoicing law.{{PROBLEM_SUMMARY_1_SENTENCE}}

Proposed Solution: Bilko — a Fiken-inspired SaaS at €8-25/month with SEF e-invoicing, PDV auto-calculation, double-entry bookkeeping, bank reconciliation, and financial reports in Serbian/Bosnian/Croatian.{{SOLUTION_SUMMARY_1_SENTENCE}}

Expected Outcomes:

• 100 paying organizations within 90 days of Serbia launch{{OUTCOME_1}}
• €500 MRR by end of Month 3 post-launch{{OUTCOME_2}}
• 80% activation rate (users create their first invoice within 7 days)
• Full SEF compliance for all invoices submitted through Bilko{{OUTCOME_3}}

Investment: €11,000–17,000{{BUDGET_RANGE}} EURNOK | Timeline: ~10 weeks to Serbia launch{{DURATION}} | Priority: High — CEO GO decision 2026-02-20{{HIGH/MEDIUM/LOW}}

3. Current State Analysis (AS-IS)

3.1 Current Process Overview

A typical Serbian SMB owner currently manages accounting through one of three workflows:

1. Pantheon/Minimax desktop software — installed locally, managed by an accountant, significant monthly cost (€100-200+), complex interface
2. Manual spreadsheet + paper invoices — technically illegal post-2023 SEF mandate; exposes business to fines
3. Outsourced accountant only — accountant submits SEF invoices manually; owner has no real-time visibility into finances

None of these provide: (a) real-time cloud access, (b) affordable self-service, or (c) simple enough UX for non-accountants.{{CURRENT_PROCESS_DESCRIPTION}}

3.2 AS-IS Process Flow

4. Future State Vision (TO-BE)

4.1 Future State Description

With Bilko, a Serbian SMB owner opens their browser, creates a compliant e-invoice in under 5 minutes (including line items, PDV, multi-currency), and submits it directly to SEF without touching the government portal. Expenses are categorized automatically. Bank statements are imported via CSV and matched to transactions. At month end, the PDV report is generated in one click and exported in the format required by Poreska Uprava. The owner has real-time P&L, cash flow, and balance sheet visibility from any device.{{TO_BE_STATE_DESCRIPTION}}

4.2 TO-BE Process Flow

5. Market Analysis & Competitive Landscape

5.1 Market Context

The Balkan region has 348,000+ active SMBs across Serbia (300K+), Croatia (140K+), and Bosnia-Herzegovina (~80K VAT-registered). The 2023 Serbian SEF mandate and January 2026 Croatian eRačun mandate create regulatory forcing functions that are driving digital adoption at a pace not seen since SEPA in Western Europe. The €50-150M TAM is currently served by legacy ERP vendors (Pantheon, Minimax) who have not modernized their UX or pricing to match the SMB segment.{{MARKET_CONTEXT_PARAGRAPH}}
