Services
What our software development company delivers
Each project gets a written scope, clickable designs before coding, and a handover with documentation.
Dashboards and admin panels
Admin screens to manage orders, users, content and payments, plus dashboards with the figures managers check daily. IELTS Test BD's 18-screen admin handles tests, candidates, scoring and manual mobile-payment approval.
SaaS and internal tools
Subscription products for outside customers or tools used only inside your company. We set up accounts, roles, billing records and audit logs, and plan the database so new features can be added later without a rebuild.
API and third-party integrations
Connections to payment gateways, courier services, SMS providers, accounting software and Google or Meta tools. NextGen Mobile's order tracking by phone number is an example of linking checkout data to a customer-facing lookup.
Proof
Builds that show admin panels and custom logic
IELTS Test BD shows an 18-screen admin, autosave through dropped connections and manual payment approval, the parts an internal tool for a Karwan Bazar office needs. Mystic Shop BD shows courier and local wallet integrations, and NextGen Mobile shows order tracking by phone number.

Questions
Questions for an IT company in Karwan Bazar
Is Rizer an IT company in Karwan Bazar with an office there?
No. We have no office in Karwan Bazar. We work remotely with businesses across Dhaka, with calls, shared designs and a staging version of the app you can test at any time.
What does web application development in Karwan Bazar, Dhaka usually involve?
It starts with a call about the task the app must handle, then a written scope, screen designs, development in stages and testing with your staff. At launch we deploy the app, hand over code and logins, and stay on for refinements.
What sets the cost of custom software for a Karwan Bazar business?
Cost follows the number of screens and user roles, the complexity of the business rules, the integrations needed, data migration from old systems and any reporting. We send a quote after the free 15-minute call, once the scope is clear.
Can you connect new software to the systems we already use?
Yes, if those systems offer an API or a data export. We have integrated payment gateways, couriers and tracking tools. Where no API exists, a scheduled spreadsheet import is often enough to keep both systems in step.
Who owns the code once the software is finished?
You do. We deliver the source code, database access and documentation at handover.
Will the app keep working on a weak connection?
We design for it where it matters. IELTS Test BD saves answers automatically, so a dropped connection does not lose a candidate's work. The same approach suits order entry or field reports from staff on mobile data.
