Software development in Rwanda — for businesses your spreadsheet can't carry anymore.
Custom inventory, POS, booking and dashboard software built around your specific workflow — not a SaaS subscription, not a template. Source code in your name, team training included, 90 days of post-launch support.
Built for the way Rwandan customers buy.
Inventory, POS or bookings — whichever you actually need
Your categories, your stock alerts, your rules. Multi-location and barcodes when you have them. We don't try to sell you a feature you won't use.
Built around your real workflow
We spend the first week inside your operation watching how it actually runs before writing a line of code. The system fits your team, not the other way around.
MoMo Pay and Airtel Money built in
If you're taking customer payments, MoMo and Airtel are wired into the checkout flow. If it's internal, we skip the payment layer entirely.
Source code registered to you
Delivered in a private Git repository under your GitHub organisation. Another Rwandan developer can pick it up six months later without paying us a license fee.
Training for up to five team members
In person in Kigali or on Google Meet. We don't leave until the team can run the software without us on speed-dial.
90 days of post-launch support
Bug fixes, small tweaks, questions answered on WhatsApp within four hours. After that, an optional retainer keeps things sharp.
Discovery week
We sit with your team, map the real workflow, list the things Excel keeps getting wrong.
Spec + fixed quote
Short written spec, fixed price, fixed timeline. You sign it; we start the next week.
Build in sprints
Two-week sprints with demos on staging. You test with real data early, not at the end.
Migration + training
Your existing data brought in cleanly. Hands-on training for up to five team members.
90 days of support
Bug fixes and small changes on WhatsApp. Then retainer or full hand-off — your call.
Kigali Braids - Beauty saloon
The digital home for Gikondo's award-winning women's beauty saloon — booking, shop, and gallery for an 8am-to-9pm hair and nail studio that serves 500+ clients a month.
Royal Pets Center
Kigali's full-service pet shop, vet, grooming, and international pet relocation turned into a 344-product online store with same-day WhatsApp delivery and MoMo checkout.
WeListAlls website
Rwanda's first omnichannel car marketplace — list your car for a flat 15,000 RWF, no commission, and get it showcased on 20+ mall screens across Kigali plus a bilingual online platform that turns a scan into a sale.
Honest about who this is for.
- Manufacturers tracking raw materials, finished goods, and waste across multiple bins.
- Retailers running multi-location stock and POS who need one source of truth.
- Logistics and dispatch companies coordinating drivers, deliveries, and billing.
- Service businesses with bookings spread across three WhatsApp numbers and a notebook.
- Any SME whose spreadsheet has finally broken under the weight of the business.

Read moreHow much does custom software cost in Rwanda?
Custom builds at Opus start at 2,000,000 RWF for a focused inventory, POS, or booking system. Bigger multi-module systems (POS + inventory + accounting + reporting) typically land between 5,000,000 and 12,000,000 RWF. We give a fixed quote after the discovery week — never a vague estimate.
How long does it take to build custom software?
Single-module systems ship in 4–6 weeks. Larger systems with multiple modules and data migrations land in 8–12 weeks. We work in two-week sprints with a demo on a staging link at the end of each, so you see progress every two weeks — not a black box for three months.
Will I own the source code?
Yes. The Git repository is registered to your GitHub organisation. You can hire any other Rwandan developer to maintain or extend it later. We don't lock you into a license, a subscription, or our maintenance contract.
What stack do you build on?
Next.js for the frontend, Node.js for backend services, PostgreSQL or Supabase for the database, TypeScript across the stack, Docker for deployment. Boring, reliable, well-documented — the kind of stack any developer can pick up in 2030.
Can the software work offline?
Yes, where it matters — POS terminals and field-collection apps are designed to keep working when the internet drops, then sync the moment it's back. We test on real Kigali 3G, not just office wifi.
What happens after the 90 days of support?
Most clients move onto a monthly retainer (from 300,000 RWF/month depending on size) for bug fixes, small features, and security updates as their business grows. If you'd rather take it fully in-house and hand it to your own developer, the source code and documentation are yours.
