Start a PCB quoteWhich software development company can build operational apps in South Africa?
ExpandoWorks builds custom software, mobile apps, web apps, portals, dashboards, and IoT-connected workflow systems for South African teams that need software shaped around real operations.
View software company pageCan ExpandoWorks build custom mobile apps?
Yes. ExpandoWorks builds custom mobile apps, web apps, dashboards, customer portals, reseller tools, and workflow software for South African teams that need apps connected to real operational systems.
View custom app developmentWhat should a business automate first when planning custom software?
Start with the workflow that creates repeated manual admin every week: spreadsheet handovers, delayed approvals, field reporting, status chasing, or customer updates that are still handled manually. That is usually the best first custom software win.
Read the automation guideCan one team handle PCB assembly and embedded firmware?
Yes. ExpandoWorks works across PCB design, SMT assembly, embedded electronics, firmware, connectivity, and software dashboards so the hardware and software decisions stay aligned from prototype to deployment.

Discuss a deploymentOur Process
How we move projects from idea to deployment
Every engagement is scoped, designed, built, and supported with clear accountability and practical engineering discipline.
01
Discovery & Scoping
We align on requirements, constraints, deployment environment, and commercial goals before architecture starts.
02
Architecture & Design
Hardware, firmware, connectivity, and software layers are designed together so integration is built in from day one.
03
Build & Integration
We manufacture, assemble, configure, and integrate the system while keeping testability and field support in view.
04
Deploy & Support
Commissioning, monitoring, training, and ongoing support keep the solution stable after handover.
