About
Built by people who've done the integration work themselves.
Phrowler exists because most e-invoicing and ERP compliance deadlines get treated as paperwork — until someone has to actually wire SAP, Sage, Dynamics 365, and Oracle into a regulator's API. That's the work we specialize in.
The engineer behind Phrowler
Phrowler is led by Osama Ahmed Siddiqui, a systems integration engineer and full-stack AI developer with five-plus years across backend engineering, cloud infrastructure, and ERP systems spanning SAP ABAP & S/4HANA, ERPNext/Frappe, Sage (50, 200, Evolution & X3), Microsoft Dynamics 365, and Oracle Fusion.
That background includes shipping Nigeria FIRS and Pakistan FBR e-invoicing pipelines for 15+ Tier-1 clients, publishing four apps on the Frappe Marketplace, and building production AI systems — RAG/LLM applications, computer vision with YOLOv8, and n8n workflow automation — for clients running at real scale.
Phrowler brings that same hands-on approach to every engagement: no handoff between the people who scope the work and the people who build it.

How we work
Scope it honestly
We tell you upfront what's a two-week integration and what's a two-month one, before any contract is signed.
Build against production
Compliance and integration work fails in the details. We test against real ERP instances and real data, not sandboxes that don't match reality.
Hand over something maintainable
Documentation and a clean handoff are part of the deliverable, not an afterthought.
