Booking & scheduling systems
Let customers book a room, slot or service online — with availability, confirmations and reminders — instead of phoning back and forth. Ideal for guest houses, salons and service businesses.
Web & mobile apps
Custom web & mobile app development
A web application is custom software that runs in the browser or on a phone — a booking system, dashboard or client portal — built around how your business actually works. Avuno Technologies designs and develops web and mobile apps for South African businesses, from guest-house booking tools to job-tracking systems for the trades.
Key takeaways
- A web app does work — bookings, logins, dashboards — where a website mostly presents information.
- Avuno builds booking systems, admin dashboards, client portals, PWAs, internal tools and API integrations.
- Apps are mobile-first, secure and POPIA-aware, delivered in staged milestones you can test as they ship.
- Custom apps are quoted on scope, typically R12,000–R40,000+, starting with a free discovery call.
- Every build is priced in Rands and owned by you — your domain, your data, your asset.
What can Avuno build?
Avuno builds custom web and mobile applications that handle a real job inside your business — taking bookings, tracking work, giving clients a private login, or replacing a tangle of spreadsheets and WhatsApp messages. Below are the kinds of apps we build most often for South African small and medium businesses, each shaped to your workflow rather than forced into an off-the-shelf template.
Dashboards & admin panels
A single screen that shows what matters — jobs, leads, stock or revenue — and lets your team update it in seconds. Replace the spreadsheet everyone is afraid to break.
Client portals
Give customers a secure login to view quotes, invoices, project status or documents. Looks professional, cuts the back-and-forth, and keeps everything in one place.
PWAs & mobile apps
Progressive web apps install on a phone's home screen, work offline and send push notifications — a native-feeling app without app-store cost or delays.
Internal tools
Custom software for your team — quoting tools, job trackers, inventory or reporting — that fits exactly how you work and removes hours of manual admin each week.
Integrations & APIs
Connect your app to payment gateways, calendars, email and accounting tools through their APIs, so data flows automatically instead of being re-typed by hand.
How we build apps
Avuno builds apps the modern way: a clean, secure codebase, a mobile-first interface that works on the cheap Android phone your customer actually carries, and security built in from the first line rather than bolted on later. Data handling is POPIA-aware by default, traffic is served over Let's Encrypt SSL, and forms and logins are protected so your customers' information stays safe.
Crucially, we deliver in stages. Instead of disappearing for two months and returning with a finished-or-broken product, Avuno ships a working core first, then adds features in agreed milestones. You test each stage on real devices, give feedback, and often start using the app before the last feature lands. It keeps the project honest, the budget visible, and the result genuinely fit for how your business runs.
What does a web app cost?
Custom web apps are quoted on scope and typically run R12,000 to R40,000 or more, depending on how many features, user roles and integrations the app needs. A simple booking tool sits near the lower end; a multi-role portal with payments and a dashboard sits higher. There are no monthly licence traps — you pay a fixed, written once-off build price in Rands, with optional care plans and hosting from R300 per month to keep it running.
Every project starts with a free discovery call so we can scope it accurately before quoting. You'll get a clear written proposal — what's included, what it costs, and how it's staged — within one working day, with no obligation to proceed.
How long does it take?
A focused web app is staged over weeks rather than delivered in days. After the discovery call and proposal, Avuno builds the core first and adds features in milestones, so a straightforward booking system might be live in a few weeks while a larger portal runs longer. Because delivery is staged, you see progress continuously and can start using the working parts early instead of waiting for one big launch.
Web app vs. off-the-shelf software
Many businesses reach for a generic SaaS subscription and then bend their workflow to fit it. A custom app does the opposite — it fits your business. Here's how the two compare for a typical South African SMB.
| Factor | Off-the-shelf SaaS | Custom Avuno app |
|---|---|---|
| Fit to workflow | You adapt to the tool | Built around how you work |
| Cost shape | Monthly fees, per user, forever | Once-off build, low monthly hosting |
| Ownership | Locked to their platform | You own the app & data |
| Local payments | Often US-only gateways | PayFast, Yoco, EFT built in |
| Changes | Wait for the vendor | We build what you ask for |
Examples relevant to SA SMBs
The best way to picture a web app is through real local examples. A few Avuno builds, or builds we scope often:
- Guest-house booking system. A coastal B&B replaces phone-and-email bookings with an online calendar — guests see availability, book and pay a deposit via PayFast, and the owner gets an instant confirmation and a tidy dashboard of upcoming stays.
- Trade job-tracking tool. An electrician or plumber logs jobs, assigns them to the team, attaches photos and marks them complete from the phone on site — so quotes, jobs and invoices stop living in a notebook and WhatsApp.
- Client portal for a consultancy. Clients log in to see project status, approve quotes and download documents, cutting the endless "can you resend that?" emails and making a small firm feel established.
Frequently asked questions
What is the difference between a website and a web app?
A website mainly presents information — pages about your services, contact details and photos. A web app does work: it lets people log in, book a slot, manage data or run a process. Avuno builds both, and many projects start as a website with one or two app features bolted on, such as a booking form or a client login.
How much does a web app cost in South Africa?
Custom web apps from Avuno are quoted on scope and typically run R12,000 to R40,000 or more, depending on the number of features, user roles and integrations. A short discovery call lets us scope it accurately, and you always get a fixed written quote in Rands before any work begins.
Do you build mobile apps or just web apps?
Avuno builds progressive web apps (PWAs) that install on a phone's home screen and work like a native app — including offline support and push notifications — without the cost and friction of the app stores. For most South African small businesses a PWA delivers the mobile experience customers want at a fraction of native-app budgets.
How long does it take to build a web app?
A focused web app is usually staged over several weeks rather than days. Avuno delivers in stages — a working core first, then features added in agreed milestones — so you can see real progress, test as you go, and start using the app before every last feature is finished.
Can you integrate payments or other tools into my app?
Yes. Avuno integrates South African payment gateways such as PayFast and Yoco, plus email, calendars, accounting tools and other services through their APIs. If your business already relies on a tool, the app can usually connect to it so data flows automatically instead of being re-typed by hand.
