Custom web apps
Software built around how your business works: who signs in, what each person sees, and the steps an order, booking or application moves through.
Rizer is a software development company in Bangladesh that builds custom web apps, dashboards, admin panels, SaaS and internal tools, and connects them to payment, courier and third-party APIs. For Bangladeshi clients we have built an IELTS test platform with an 18-screen admin and 2 commerce platforms that run with no platform subscription. Rizer has 8+ years of delivery, 120+ projects and a 4.9 average rating from 50+ reviews.
A public site, a timed testing engine for all 4 IELTS skills, AI Speaking scoring, mobile-transfer payments and 3 role-based workspaces.
As a custom software development company in Bangladesh, we build 6 kinds of software. All of it runs in the browser on phones and desktops.
Software built around how your business works: who signs in, what each person sees, and the steps an order, booking or application moves through.
Admin screens that open on the decisions waiting for your staff. The IELTS Test BD admin lists writing reviews, payments awaiting approval and new registrations first.
Tools your team uses every day, or software you sell to other businesses by subscription, with a separate workspace and permissions for each role.
Screens are designed and prototyped before development. On the IELTS Test BD dashboard, each module shows Start, Resume or Result.
Mystic Shop BD connects bKash, SSLCommerz and manual Nagad payments, books Pathao and Steadfast parcels from the order, and sends server-side events to the Meta Conversions API.
IELTS Test BD transcribes Speaking answers recorded in the browser and returns a band estimate on 4 criteria. Malformed model output is rejected, and an admin can correct or finalise every band.
8 kinds of business software we build to order. The first 4 are documented in our case studies. The last 4 have no case study yet and are scoped on the free call.
Rizer does not publish a price list for custom software development in Bangladesh. The quote follows a free 15-minute call and rests on these 6 factors.
How many kinds of user sign in and what each may do. IELTS Test BD has 3 workspaces: student, teacher and admin.
The number of screens, forms and reports. The IELTS Test BD admin alone has 18 screens in 4 areas.
Each gateway, courier, SMS or email provider adds build and testing time. Mystic Shop BD connects 5 payment methods and 2 couriers.
Transcription, scoring and automatic emails need validation and a review step. On IELTS Test BD, an admin can correct any AI band.
Moving existing records from spreadsheets or old software into the new database adds work to the quote.
Mystic Shop BD pays $0 a month for platform hosting within Cloudflare's free allowances; domain, gateway, SMS and email costs are separate. Updates to owned code need a developer.
6 points to compare before you buy a subscription or commission a build. When your process is standard, ready-made software is the better choice, and we will say so on the call.
What each system does on the server and in the admin, with a link to the full case study.

The online mock test platform of British Language Club, an IELTS and visa processing centre in Rajshahi. Answer keys stay on the server and are used only for scoring. New tests and Speaking variations are added in a 4-step builder with no development work.
React and TypeScript on Cloudflare Pages, Supabase Postgres with row level security

A full commerce platform for a retailer selling across Bangladesh, from storefront and checkout to inventory, returns and analytics. Risk scoring, a phone and IP blocklist and a verification step check cash-on-delivery orders before a courier is booked.
Cloudflare Workers and D1, TypeScript and a React admin console

A custom storefront and order console for a Rajshahi phone store. The search engine was written for this catalogue, with typo tolerance, a 31-entry synonym table, and Bengali and English tokenization.
1 Cloudflare Worker, 0 runtime dependencies
These figures cover all Rizer work, for Bangladeshi and international clients.

We test every role and payment path on phones and desktops, then check speed once the system is live.

They should be checked on the server. On IELTS Test BD, promo codes are validated on the server and answer keys are never sent to the browser.
On IELTS Test BD, answers save to the server and to a local draft. On NextGen Mobile, rapid taps in the cart are queued so a double tap cannot produce a wrong total.
Ask whether you receive the source code and whether customer data sits in an account you control. Mystic Shop BD holds its full source code, database schema and deployment configuration.
Custom software has a higher first cost than a monthly subscription, and every later change is developer work. On NextGen Mobile, adding a handset is a request to Rizer.
