Off-the-shelf software rarely fits the way your business actually works. Serina Systems designs and builds custom software around your processes, so your team stops fighting spreadsheets, paperwork and tools that were never made for you.
We start by understanding how your business runs today, then build a secure web-based system with the exact features, user roles and reports you need. It works on any device, connects to M-Pesa and the tools you already use, and grows as your business does.
What We Build
If a task in your business is slow, repeated or done on paper, it can usually be turned into a system. These are the kinds of custom software we build most often.
One system for your staff, customers, tasks and records, replacing scattered files and spreadsheets.
Track stock in and out, set low-stock alerts and see what is selling across shops or stores.
Fast point-of-sale, invoicing and receipts that record every sale and every payment.
Online booking with reminders for clinics, salons, hotels, venues and service businesses.
Student records, fees, results and parent communication in one organised place.
Give customers a secure login to see orders, documents and updates, and keep every lead in one list.
Connect your system to M-Pesa Daraja, Paystack, email, SMS and the other tools you already use.
New features, security updates, bug fixes and performance tuning after your system goes live.
Software made for your business removes the daily friction. Your team works faster, your records stay accurate and you can see how the business is doing without chasing anyone for a report.
The system follows how you work, so your team does not have to change habits to suit the software.
Automate repeated tasks and replace manual entry to save hours every week.
Live reports and dashboards show sales, stock and performance at a glance.
It is your system. We hand over hosting access and the source code to you, unless we agree otherwise.
We pick proven tools for each project so your software is fast, secure and easy to maintain.
No hidden extras. These essentials come standard with every software project we deliver.
A clear six-step roadmap takes your system from first conversation to a live, working product.
We sit down with you and your team to learn how the business runs today, where time is lost and what the system must achieve.
We map the screens, user roles and data, then share a clickable prototype so you can see and approve the system before we build it.
We build the system in short stages, so you see real progress and can steer it as it takes shape.
We test every feature with realistic data on different devices, fix bugs and check security and speed before anyone relies on it.
We move your data across, set up hosting, go live and train your team so everyone is confident from day one.
After launch we stay close, fixing issues quickly, keeping the system secure and adding features as your business grows.
The cost depends on the number of features, user roles, integrations and reports you need. After a free consultation we send a clear, fixed quote so you know the full cost before we start.
A focused system can take around four to eight weeks, while larger systems with several modules and integrations take longer. Your proposal includes a clear schedule, and you see progress along the way.
Ready-made software is a good choice when your needs are standard. Custom software makes sense when your process is different, you are paying for features you never use, or you need your tools to work together. We will tell you honestly if an existing product would serve you better.
Yes. We integrate M-Pesa Daraja and Paystack so customers can pay online and every payment is recorded in your system automatically. Payment provider accounts and transaction fees are set up and paid directly by you.
You do. We set up hosting on your behalf and hand over full control, including the source code, unless we agree otherwise in your proposal. Your business data stays yours.
We stay with you. We fix issues, keep the system secure and updated, and add new features whenever you are ready.
