If you are the CIO of a bank, IT director of a payment institution, or CTO of a fintech in the Maghreb or Africa, you have probably discovered that off-the-shelf banking solutions don't handle your reality. Cash management, interbank payments, SWIFT reconciliation, Central Bank specifics — all of this requires custom.
This guide is written by engineers who have shipped banking systems in production — for banks in Algeria, the Maghreb and MENA.
Why banks need custom software
Packaged banking solutions (Temenos, Finastra, Sopra Banking) cost $500K to $5M in licensing — before implementation. For a regional Maghreb bank or a growing fintech, that is often 2-3 years of IT budget consumed on licensing alone.
Custom becomes the right choice when: your core banking is a 2000s legacy nobody can modify, when local regulation imposes formats that international solutions don't support natively, and when your competitive advantage relies on processes you cannot force into a standard package.
The 5 modules of a banking cash management system
Module 1: Real-time treasury position. Consolidated view across all accounts, currencies, correspondent banks. Real-time via SWIFT MT940/MT942 and local clearing system APIs.
Module 2: Cash forecasting. ML model trained on local data beats Excel forecasts by 30-50% in accuracy.
Module 3: Automatic reconciliation. AI matching system auto-reconciles 92-97% of transactions. Rest escalated for manual review with pre-filled context.
Module 4: Interbank payment management. Initiation, validation, tracking via national clearing systems. Dual validation, full audit trail, AML compliance.
Module 5: Regulatory reporting. Auto-generates Central Bank reports. What 3 people do in 5 days, the system generates in 5 minutes.
Technical architecture — what holds in banking production
Database: PostgreSQL with synchronous replication. Financial data requires ACID transactions, immutable audit trail, and point-in-time recovery.
Messaging: Apache Kafka for transaction events. Every transaction is an immutable event. Enables replay, audit, and async integration.
API: gRPC between internal services, REST for interfaces. Banking systems process thousands of transactions per second — gRPC offers 5-10x performance over REST.
Security: end-to-end encryption, HSM for keys, zero-trust. Cryptographic keys live in FIPS 140-2 certified HSM, never in application memory.
«A banking cash management system is not a web app with a database. It is a distributed architecture with requirements 90% of developers have never encountered.»
Compliance — what the Central Bank requires
Algeria: Bank of Algeria mandates monthly reporting on FX positions, treasury situation, interbank commitments.
Morocco: Bank Al-Maghrib requires Basel III compliance, COREP/FINREP reporting, SIMT integration.
Tunisia: Central Bank of Tunisia mandates daily FX declarations and monthly prudential reporting via SIBTEL.
For fintechs: quarterly activity reports including transaction volumes, fraud rates, KYC/AML indicators.
Real cost and timeline
Complete cash management (5 modules): 15-50M DZD. Timeline: 6-12 months.
Regulatory reporting module alone: 3-8M DZD. Timeline: 2-4 months. Often first delivered for immediate ROI.
SWIFT integration: 2-5M DZD additional. Requires SWIFT certification.
Compared to Temenos/Finastra: custom costs 5-10x less in licensing (no license, code is yours) and 2-3x less in implementation.

Why us — and not a Temenos integrator
We are not a packaged solution reseller. We are an engineering workshop that builds banking systems from scratch. Code is yours from day 1. No annual license. No vendor lock-in.
We deliver from Algiers with local presence, dinar invoicing, and direct knowledge of Maghreb regulatory requirements. We speak French, Arabic and English — the three languages of Maghreb and MENA banking.
