The Problem

Common challenges we solve

We've delivered api integration projects across dozens of Bangladesh enterprises. Here's what we hear most often.

Staff re-enter data across 3–5 disconnected systems

The same customer, the same order, the same payment — entered separately in sales, inventory, and accounting. Every manual entry is a chance for error.

Monthly reconciliation takes days

When systems don't talk to each other, finance staff spend the first week of every month matching records across platforms manually.

No real-time visibility across operations

Sales closed yesterday, but inventory won't reflect it until someone enters it manually. Decisions are always based on stale data.

Payment confirmation is manual and slow

bKash, Nagad, and bank payments arrive but aren't automatically matched to invoices — creating customer complaints and accounting gaps.

FAQ

API Integration — Common questions

Can you integrate systems that don't have APIs?+

Yes. For legacy systems without APIs, BSD builds integration layers using database connectors, file-based ETL, or screen scraping where necessary.

How do you handle integration failures?+

Every integration includes retry logic, dead-letter queues, and automatic alerts. Failed transactions are logged and can be replayed — no data is lost.

Can you integrate with bKash and Nagad for automatic payment matching?+

Yes. BSD integrates with bKash, Nagad, and SSLCommerz APIs to automatically match incoming payments against invoices and update your accounting system.

How long does a typical integration project take?+

Single-system integrations (e.g., payment gateway) take 2–4 weeks. Multi-system enterprise integration projects typically run 6–12 weeks depending on complexity.
