You have three quotes sitting in your inbox. One is R40,000. One is R250,000. One is R900,000. They are all for the "same" project.
This is not unusual. It is the reality of buying custom software in South Africa. And it happens because "the same project" means something completely different to each developer who quoted it.
I have been building custom software in South Africa for 14 years. I have seen projects range from R15,000 to well over a million rand. Here is an honest breakdown of what things actually cost and why.
Why Quotes Vary So Much
When you ask three developers to quote on "a booking system" or "a customer portal," each one imagines a different thing.
Developer A hears "booking system" and quotes a form connected to a calendar. Two weeks of work. R40,000.
Developer B hears "booking system" and quotes a multi-location booking platform with staff management, payment integration, automated reminders, and a customer-facing portal. Eight weeks. R250,000.
Developer C is an agency. They hear "booking system" and quote discovery workshops, UX research, wireframes, design sprints, development, QA, deployment, and a six-month support contract. R900,000.
None of them are wrong. They are quoting different things because the scope was not defined.
The most important thing you can do before asking for quotes is define what you actually need. Not how it should look. What it should do. What data goes in. What comes out. Who uses it. What happens when something goes wrong.
A clear scope document cuts quote variance by 70% or more.
What Drives Cost
Four factors determine what custom software costs.
1. Complexity
A simple CRUD application (create, read, update, delete records) is straightforward. Think: a task tracker, a simple CRM, a product catalogue with admin.
A complex application has business logic, conditional workflows, multi-user permissions, real-time data, reporting, and integrations with external systems. Think: a POS system processing thousands of transactions daily, a medical practice management system with billing and clinical records, or a multi-branch operations platform.
Simple applications cost less because they have fewer moving parts. Complex applications cost more because every edge case, every rule, and every integration point takes time to build correctly.
2. Integrations
Does your software need to talk to other systems? Payment gateways (PayFast, Yoco, Peach). Accounting software (Xero, Sage). Email systems. SMS providers. ERPs. Logistics APIs.
Each integration is a separate piece of work. The difficulty varies wildly. Integrating with a well-documented API like Stripe takes a day. Integrating with a legacy ERP that uses flat-file exports takes a week or more.
Budget R5,000 to R30,000 per integration, depending on the API quality and data complexity.
3. Number of Users and Scale
Software for a team of 5 people is different from software for 350 employees across 7 branches. Scale affects architecture, hosting costs, security requirements, and performance work.
A system processing 50 transactions per day can run on simple infrastructure. A system processing 5,000+ transactions daily needs careful database design, caching, monitoring, and redundancy.
4. Platform
A web application is one platform. Add a mobile app and you have two platforms. Each platform roughly doubles the front-end development effort. The backend can often be shared, but the mobile app itself (or the responsive web version) requires its own design and development.
Realistic Cost Ranges (2026)
These are ranges based on working with an experienced solo developer or small team in South Africa. Agency pricing is typically 2x to 4x higher for comparable work.
WordPress / WooCommerce Site
- Simple business site (5-10 pages, contact form, basic SEO): R15,000 to R40,000
- WooCommerce store (product catalogue, checkout, payment gateway): R40,000 to R100,000
- Complex WooCommerce (custom plugins, integrations, multi-vendor): R100,000 to R250,000+
Shopify Store
- Theme setup and configuration: R15,000 to R40,000
- Custom theme development: R40,000 to R100,000
- Custom Shopify app: R30,000 to R150,000+
- Shopify Plus with checkout extensions: R100,000 to R300,000+
Custom Web Application
- Simple (single-purpose tool, 1-3 user types, basic features): R50,000 to R150,000
- Medium (multiple modules, user roles, reporting, 1-2 integrations): R150,000 to R400,000
- Complex (multi-module platform, many integrations, high transaction volume): R400,000 to R1,200,000+
API / Integration Work
- Single API integration (connect two systems): R10,000 to R40,000
- Multi-system integration (middleware connecting 3+ systems): R50,000 to R200,000
- Custom API server (build an API for your system): R30,000 to R120,000
Mobile Application
- Simple companion app (for an existing web system): R60,000 to R150,000
- Full mobile application (React Native or native): R150,000 to R500,000+
These ranges are wide because the details matter enormously. "A custom web application" can mean a simple internal tool or a full enterprise platform. The more precisely you define what you need, the more precisely it can be quoted.
Solo Developer vs Agency vs Offshore
Solo Developer (like me)
- Hourly rate range: R500 to R1,200/hour
- What you get: Direct communication with the person writing the code. No project manager layer. Fast decisions. The person who scoped it is the person who builds it.
- Tradeoff: One person's capacity. If the project is genuinely large (6+ months full-time), a solo developer may not have the bandwidth.
Agency
- Hourly rate range: R1,200 to R3,000/hour (blended rate across roles)
- What you get: A team. Designers, project managers, developers, QA. Formal process. More capacity for large projects.
- Tradeoff: Higher cost. Communication goes through layers. The person who sold you the project may not be the person who builds it. Agency overhead (offices, managers, sales staff) is built into your rate.
Offshore (India, Eastern Europe, Philippines)
- Hourly rate range: R200 to R600/hour
- What you get: Lower rates. Larger available talent pool.
- Tradeoff: Time zone differences. Communication challenges. Quality varies enormously. Cheap is not always affordable when you factor in rework, miscommunication, and support after delivery. Many SA businesses have come to me to rescue projects that were started offshore and abandoned.
The right choice depends on your project, your budget, and your tolerance for communication complexity. There is no universally correct answer.
How to Evaluate a Quote
When you receive a quote, look for these things.
Does it include a scope document? A quote without a scope document is a guess. The scope should describe what will be built, what will not be built, what technologies will be used, and what assumptions were made.
Does it specify what happens after delivery? Who fixes bugs? How long is the warranty period? What does ongoing support cost? A developer who does not mention post-launch support is planning to disappear after the last payment.
Does it include a timeline? "It will take a few months" is not a timeline. Week-by-week or milestone-based timelines show the developer has actually thought through the work.
Does it distinguish between must-haves and nice-to-haves? A good developer will help you prioritize features and suggest a phased approach: build the core first, then add features based on real usage. A developer who says "yes" to every feature in one big quote is either overcharging or underestimating.
Can the developer show you similar work? Not a portfolio of pretty screenshots. Working software they have built that does something similar to what you need. Ask about the scale, the challenges, and whether the client is still using it.
A Real Example
I built a custom point-of-sale system for a recycling company. Seven branches. 350 employees. 5,000+ transactions processed daily. The system handles pricing by weight, multi-branch inventory, cash management, supplier payments, and reporting across the entire operation.
This was not a simple project. It replaced manual and spreadsheet-based processes. It handles real money, real inventory, and real operations every day.
The Short Version
Custom software in South Africa costs between R15,000 for a simple website and R1,200,000+ for a complex multi-module platform. The exact price depends on complexity, integrations, scale, and who builds it.
The biggest factor in getting an accurate quote is defining what you actually need before you ask for one. The biggest factor in getting good value is choosing a developer who has built something similar before.
