Key Questions & Direct Answers
How can a Sri Lankan business sell online internationally with Stripe?
A business can accept international card payments seamlessly by deploying a custom Next.js storefront integrated with Stripe Checkout or Stripe Elements, supporting multi-currency billing (USD, JPY, GBP, AUD) and automated receipt generation.
Knight Graphics architected this exact solution for Takumi Halal Mart in Chiba-ken, Japan, allowing customers across all Japanese prefectures to order authentic halal groceries with single-click card checkout and zero currency conversion errors.
How much does an e-commerce website cost to build in Sri Lanka?
Custom e-commerce web development starts from Rs. 180,000 (approx. $600 USD) for high-performance direct storefronts, scaling up to Rs. 450,000+ ($1,500+ USD) for multi-vendor, cross-border multi-currency platforms.
Every store includes mobile-optimized inventory catalogs, automated cart management, payment gateway integration, automated email/WhatsApp order confirmations, and search engine optimization.
What payment gateways are supported for Sri Lankan e-commerce stores?
We integrate Stripe (ideal for international USD/JPY/EUR payments), PayHere (supporting Sri Lankan Visa/Mastercard, FriMi, Genie, and eZ Cash), WebXPay, and direct bank transfer / Cash on Delivery (COD) workflows.
We configure payment routing to automatically present the best checkout option depending on whether the customer is browsing from Sri Lanka or abroad.

E-Commerce Solutions FAQs
Honest, detailed answers about deliverables, timelines, revisions, and ownership.
01Do you charge a monthly percentage fee on our sales?
No. Unlike proprietary platforms like Shopify that take transaction percentages, Knight Graphics builds custom-owned software. You only pay standard payment gateway processing fees (e.g. Stripe or PayHere).
02Can customers place orders and pay via Cash on Delivery or Bank Transfer?
Yes. We can configure automated bank transfer workflows with slip upload prompts and Cash on Delivery options alongside card payments.
03Will our online store be easy to manage on a phone?
Yes. Your administrative management portal is fully mobile responsive, allowing you to update prices, add new items, and track orders directly from your smartphone.
04How does the store handle out-of-stock items?
The catalog includes real-time inventory tracking that automatically disables the checkout button and flags products as 'Sold Out' when stock reaches zero.
