Disclaimer
This case study reflects a representative scenario built on patterns observed in mid-market B2B distributors using D365 Business Central. Figures are for ROI estimation purposes; actual results vary based on the specific company profile.
Company Profile
Industry: B2B FMCG non-food distribution (hygiene, cleaning, HORECA supplies + retail).
Size: 180 employees (95 BC Essentials + 85 Team Members), €65M turnover, 4 regional warehouses, 28,000 active SKUs.
Customers: 320 B2B distributors (HORECA, independent retail, institutions) + direct sales on marketplaces (15% revenue).
ERP: D365 BC Essentials since 2021, local Gold partner, ~€620k initial implementation + AL customisations.
Pain points identified Q1 2025
1. Marketplace overselling: 11% during Q4 peak → marketplace chargebacks €58k/year + suspension risk.
2. Operational KAMs: 8 KAMs × 5h/day on status calls + phone orders = €281k/year inefficient cost. Distributor NPS 31, churn 19%.
3. Obsolete stock: 14% of inventory (€3.9M frozen) due to lack of AI forecasting; 8% stockouts on top-selling SKUs.
4. Fragmented EDI: 4 retailers (Carrefour, Metro, Selgros, Mega Image) with 4 different AppSource connectors, €62k/year maintenance, €28k/year penalties, 2 new retailers rejected (Auchan, Profi) due to lack of rapid EDI onboarding.
5. e-Invoicing rejections: 9.2% outbound invoices × 14k invoices/year = 1,288 invoices/year rework × €95 = €122k/year cost.
6. Statutory reporting (SAF-T): 32h/month manual reconciliation = €13.4k/year + penalty risks.
7. Couriers: Manual allocation for 5 couriers, 81% delivery SLA, high shipping costs.
The Solution — Azuvio Smart Layer over BC (zero BC core modifications)
Modular implementation in 5 months:
Month 1-2: OMS Marketplaces + EDIconnect (existing retailers + onboarding new ones like Auchan, Profi).
Month 2-3: Compliance Hub (semantic e-invoicing + SAF-T reconciler).
Month 3-4: B2B Portal for top 80 active distributors (later expanded to 320).
Month 4-5: AI Forecasting + Multi-Courier Orchestrator (14 couriers).
Total Investment: €285k setup + €260k/year recurring (all Smart Layer modules).
