Ecommerce & B2B Portals

Ecommerce & B2B Portal Development in Bangladesh

A consumer storefront and a B2B ordering portal are different products. B2B needs price tiers, credit limits, approval chains and reorder-from-history. We have built both, wired to bKash, Nagad and SSLCommerz, and to the courier APIs that actually deliver here.

Who this is for

You sell to businesses and take orders by phone, WhatsApp and PDF price list.

You have a storefront on a hosted platform and cannot get the reports or integrations you need.

You need corporate accounts with budgets, approvers and multi-location delivery.

How we build it

01 Catalogue and pricing model design — usually the hardest part of a B2B build

02 Checkout and payment flow, including failure and reconciliation paths

03 Order management and fulfilment screens for your operations team

04 Gateway sandbox testing, then live small-value transaction testing

05 Launch with monitoring on payment failures from hour one

Technology we use — and why

Not a logo wall. The reason behind each choice.

Django

Order state machines and inventory reservation logic belong in a framework with real transactions.

bKash / Nagad / SSLCommerz

We have integrated all three, including the reconciliation cases the docs do not cover.

Redis

Cart and session state, plus rate limiting on checkout.

Celery

Payment callbacks, settlement reconciliation and courier syncs run as retryable tasks.

Engagement models

We don't publish a price list. You get a band in the quote flow, and a real number after the call.

MODEL A

Fixed-scope project

Written scope, milestone plan, fixed price per milestone. Best when you know what you need built.

Paid per completed milestone

MODEL B · MOST COMMON

Monthly retainer

A committed number of senior engineering days per month. Best when scope will keep evolving.

Rolling monthly, 30 days' notice

MODEL C

Dedicated engineer

One or more engineers embedded in your team, in your standups, with architecture review from the founder.

Minimum three months

Questions people actually ask

Which payment gateways can you integrate?

bKash, Nagad, SSLCommerz and card acquiring for Bangladesh; Stripe for international. We handle the callback, timeout and reconciliation cases, not just the happy path.

Can you do B2B credit terms?

Yes — credit limits, ageing, and blocking orders that exceed the limit.

Do you build on Shopify or WooCommerce?

Only if that is genuinely the right answer, and we will tell you when it is. For tiered B2B pricing and approval chains it usually is not.

What about multi-location delivery for corporate orders?

Standard in our B2B builds: one order, many delivery addresses, one invoice.

Do you sign NDAs?

Yes, before the first call if you want.

Who owns the code?

You do, on final payment — repository, infrastructure and documentation.
