E-Commerce Website Development & Checkout Optimization
Turn casual website traffic into revenue-generating sales. Topee Solutions engineers ultra-fast custom HTML and Next.js e-commerce storefronts, high-converting mobile shopping carts, integrated payment gateways (Stripe, PayPal, GCash, Maya, PayMongo), automated inventory management, and abandoned cart recovery engines.
The Four Pillars of Our E-Commerce Engineering
We build fast, secure, friction-free online shopping experiences designed to maximize your average order value (AOV) and conversion rate.
Sub-Second Mobile Cart & Page Speed
A 1-second delay in page load drops online sales conversions by 7%. We build custom HTML5 and Next.js e-commerce storefronts that render product catalogs instantly across all mobile devices.
- Instant product image lazy-loading & WebP compression
- Sub-300ms mobile slide-out shopping cart response
- Zero layout shifting (CLS) during checkout load
- Global CDN edge distribution for international shoppers
Multi-Currency & Local Payment Gateways
Accept payments seamlessly from anywhere in the world. We integrate Stripe, PayPal, Apple Pay, Google Pay, along with local Philippines payment gateways including GCash, Maya, and PayMongo.
- Stripe & PayPal credit card processing integration
- GCash, Maya & PayMongo local wallet integration
- Automated multi-currency price calculations
- PCI-DSS compliant encrypted checkout tokens
Automated Product & Inventory Control
Effortlessly manage product variants, stock inventory levels, SKUs, sales discounts, and order fulfillment. Sync inventory automatically to prevent overselling across multiple sales channels.
- Unlimited product catalog & variant matrix (size/color)
- Real-time automated inventory stock tracking
- Batch CSV product upload & inventory import
- Automated low-stock email alerts for admin
Conversion Rate & Abandoned Cart Recovery
Recover lost revenue from shoppers who leave before completing checkout. We implement automated email sequences, 1-click upsells, customer reviews, and urgency countdown badges.
- Automated 3-step abandoned cart email recovery
- Post-purchase 1-click upsell product triggers
- Customer review stars & verified buyer badges
- Dynamic discount coupon code checkout field
Frictionless Single-Page Mobile Checkout & API Webhooks
Eliminating checkout friction while keeping inventory stock synchronized across all sales channels in real time.
1-Click Express Digital Wallet Checkout
We integrate Apple Pay, Google Pay, and GCash direct checkout buttons directly on product pages, allowing returning shoppers to purchase in 1 tap without typing lengthy billing details on mobile screens. This reduces cart drop-off rates significantly.
Automated Real-Time Webhook Synchronization
Whenever a customer places an order, automated API webhooks instantly notify your warehouse management system, update stock levels across external sales channels, and send SMS shipping tracking links to buyers automatically.
