SaaS and web platforms, from idea to paying subscribers

Subscription platforms, marketplaces and member portals with logins, billing, dashboards and admin tools, built in stages so you can launch sooner.

Web App Development

What Rocket provides

Rocket Advertising builds web platforms for founders and established businesses: subscription software (SaaS), booking and marketplace platforms, member areas and multi-company portals.

We help you define a first version that customers will pay for, build it with secure accounts and PayFast billing, and then grow it from real usage.

Who it's for

Founders with a validated idea, and businesses turning an internal tool into a product they can sell to others.

Problems it solves

  • The idea is clear but the first version keeps growing.
  • Billing, accounts and permissions are harder than expected.
  • An existing platform is slow, insecure or hard to change.

What's included

  • Product scoping and a first-version plan.
  • UX design of the key screens.
  • Secure accounts, roles and multi-company support.
  • Subscription billing and invoices.
  • Admin dashboard and reporting.
  • Hosting, monitoring and backups.

Options

  • Subscription software for a niche industry.
  • Booking or marketplace platforms.
  • Member and training portals.
  • Mobile-friendly progressive web apps.

What you'll need to supply

  • Your product idea, customers and pricing model.
  • Examples of competitors or tools you admire.
  • A decision-maker for weekly demos.

How the process works

  1. A short call to understand how you work today and what must change.
  2. A written scope with what is included, what is not, timelines and price.
  3. Design and build in stages, with demos you can test as we go.
  4. Testing with your real data and your team, then training.
  5. Launch, a review after the first weeks, and ongoing support if you want it.

Data privacy and security

Business systems hold customer names, contact details, quotes and payments. We build with role-based logins, limited access, secure hosting, backups and audit logs, and we help you apply POPIA in practice. This is practical guidance, not legal advice.

Pricing

This is quoted after a short call, because every business works differently. Ready-made solutions are usually a once-off setup fee plus a monthly subscription; custom builds are a fixed-scope project quote. All prices exclude VAT.
