Top Custom Software Development Companies in Bangladesh (2026)
Published by Kaz Software. Last reviewed November 12, 2026.
Custom software means code written for your business instead of a package you configure. If you are choosing who should build it, this guide shortlists 11 companies from our Top 25 Software Companies in Bangladesh (2026 Guide) whose own websites describe custom or bespoke development, and says what each one is best suited for. Cost is a different question; for that, read Custom Software Development Cost in Bangladesh 2026 Guide.
Disclosure: Kaz Software publishes this guide and lists itself first, where its work fits. The order follows the Top 25 and reflects editorial judgment, not an audited ranking. Facts marked "self-reported" come from each company's own website, fetched on November 12, 2026, and were not independently verified.

What to ask before you sign
Who will write the code? Ask to meet the actual engineers, how senior they are and how long they have stayed.
Who owns the source code and the repository? Insist that it lives in your own account from day one.
How is scope changed? Ask how the company handles a new requirement in week six.
Which certifications are current? Look up CMMI appraisals in the CMMI Institute's registry and ask for ISO certificate numbers.
Can you run a paid pilot of two to four weeks with one defined deliverable before committing?

Frequently asked questions
What is custom software development?
It is software written for one organisation's specific processes, instead of a ready-made package. It usually costs more up front and fits your workflow more closely.
Which Bangladeshi companies build custom software?
Among the Top 25, Kaz Software, BJIT, SELISE, Brain Station 23, Enosis, Dream71, Nascenia, Technext, Vivasoft, Mediusware and Bdtask all describe custom development on their own sites.
Is a BASIS top-10 exporter a better choice?
Not automatically. BASIS lists top exporters by export earnings, not by fit for your project. Match the company's specialty to your work and check references.
How do I check a company's claims?
Treat self-reported figures as a starting point. Verify certifications at the source, read Clutch or GoodFirms reviews and call two references.
