The short answer
Islamic core banking software handles the system-of-record functions, accounts, ledgers, transaction processing, adapted for Islamic products. A Shariah compliance layer sits alongside it, handling governance documentation, contract review and audit trails. Most institutions eventually need both, but they are different purchases with different vendors.
"Islamic core banking software" usually refers to the foundational system-of-record: accounts, ledgers, transaction processing, and product configuration, adapted to reflect Islamic contractual structures rather than interest-based ones. It is a large, expensive, long-cycle purchase, often the central IT decision for a bank.
A Shariah compliance layer is a narrower, faster-moving category. It doesn't replace core banking, it sits alongside it, handling governance documentation, contract-level review, scholar workflows and audit trails. Institutions that already have a core banking system in place, Islamic or otherwise, are often looking for this layer specifically, rather than a full core banking replacement.
We cover how the two should work together, including integration through APIs and middleware rather than replacement, in choosing the best Islamic banking software for commercial banks.
Aylinor is built as this second category, a Shariah compliance intelligence layer designed to work alongside an institution's existing core banking system, not replace it.
