Developers, travel agencies, education providers and industrial firms can hire Rizer as a remote software company in Sylhet for custom web apps, dashboards, admin panels, SaaS products and API integrations. Screens are designed and approved before development. For IELTS Test BD we built a platform that scores all 4 IELTS skills and runs on an 18-screen admin.
Updated 20 October 2026
We matched 4 documented facts about Sylhet to the kind of system an organisation there could commission.
We agree the user roles, screens and data before writing code, and you approve the screen designs before development begins.
Browser-based software for bookings, quotations, inventory, service requests or online testing. It works on phones and desktops without an app store download, and it can be built in stages so your team starts using the first part early.
Screens where managers see live figures and staff update records, with each role limited to the data it needs. IELTS Test BD's admin runs to 18 screens, and staff use it to approve the mobile-payment proof that candidates upload.
Subscription software for outside customers, or tools used only by your own staff. We build sign-up, accounts, roles, permissions and reports, with UI and UX design that gives each task a clear screen of its own.
Your system can exchange data with payment gateways, courier services, accounting software and CRMs. Mystic Shop BD connects to local wallet payments and couriers, and NextGen Mobile normalises phone numbers entered in Bengali numerals to the +880 format.
These 3 systems handle requirements a Sylhet project would share: unstable mobile connections, manual mobile-payment checks, Bengali numeral input and +880 phone numbers.
How long a build takes comes down to its roles, screens and integrations. We give you a schedule with the quote, and you approve the screen designs before coding starts.
You describe the users, the tasks and the systems involved. We send a quote.
We agree the user roles, screens, data and third-party integrations.
UI and UX design and a clickable prototype before development.
The web app, dashboards, admin panels and API integrations.
Testing with real accounts, then deployment.
Changes after launch, based on how your team uses the system.

Look at systems the company has built that are still in use, and ask who designs, codes and supports them after launch. Ask how user roles and screens are agreed before coding. Rizer has 8+ years of delivery and 120+ projects, and each project on this page has a case study.
Yes. Besides custom software we design websites, build online stores and run SEO and ads. The same team covers all of it, so your system, website and campaigns share data without a handoff between firms. We work with businesses in Sylhet remotely.
Price follows scope: how many types of user the system serves, how many screens they need, how complex the rules are, and which outside services it connects to. We scope the project with you on the free 15-minute call, then send a quote.
Yes. Screens are designed for phones first and tested on mobile data. IELTS Test BD saves each answer as the candidate works, so a dropped connection loses nothing, and NextGen Mobile runs with 0 runtime dependencies, which keeps its pages light.
Yes. After we agree the user roles and data, we design the screens and share the screen designs. Your team reviews them and asks for changes, and development begins once the flow is approved. Changes at this stage are quicker to make than changes to finished code.
Yes. We work with Sylhet organisations through video calls, shared documents and a test version of the system where you try each feature before it goes live. Rizer has no premises in Sylhet, and design, development and support all run online.
On a free 15-minute call, list the people who will use the system, the tasks it should take over and the tools already in place. We follow up with a quote by email.
