Seven out of ten carts die at checkout — 70.19% on average, 85.65% on mobile — and most of it is engineering, not marketing. We build custom stores, eCommerce apps, marketplaces, and B2B platforms with checkout treated as the product: transparent costs, guest flows, sub-second loads, every payment method. 1,200+ apps shipped, contracted through our Delaware entity.

Most stores chase more visitors while their checkout quietly bleeds the ones they already have. The numbers are precise — and the losses are recoverable.

REVENUE LEAK 01
48% abandon over surprise costs, 24% over forced account creation, and the average checkout asks 14.88 form fields. These aren’t marketing problems — they’re engineering decisions made (or skipped) during the build.
REVENUE LEAK 02
Mobile abandonment runs 17 points higher than desktop, and 57% of shoppers quit slow checkouts. A responsive template isn’t a mobile strategy — sub-second loads and thumb-first flows are.
REVENUE LEAK 03
Stores outgrow templates mid-growth: B2B pricing logic the platform can’t model, marketplace mechanics, transaction fees eating margin at volume. Replatforming under pressure costs double what planned architecture does.
From storefronts to checkout, catalog, and marketplace platforms — every build gets its conversion-critical flows scoped and fixed-priced upfront.
Conversion-engineered storefronts on Next.js and React — sub-second loads, SEO-first architecture, rich product pages, and checkouts built against the abandonment data.
Native-quality shopping apps in Flutter and React Native — where 85.65% abandonment becomes your competitive opening: one-tap wallet checkout, push-driven recovery, and offline browsing. Mobile apps
Amazon-style platforms — vendor onboarding and dashboards, commission engines, split payments, review systems, and admin tooling. True marketplace app development from a team that has shipped multi-sided platforms.
Wholesale portals with account-specific pricing, quote-to-order workflows, approval chains, credit terms, and bulk ordering — the logic that breaks template platforms, built properly.
Custom Shopify themes, private apps, and checkout extensions — because honest advice sometimes means the platform is right for you, built by people who know exactly where its walls are.
API-first storefronts decoupled from the backend — the architecture behind documented 42% average conversion lifts and 80% of adopters reporting revenue growth. One backend, every channel, no template ceiling.
Move platforms without losing data or rankings — full catalog, customer, and order migration, URL mapping with 301s, conversion upgrades shipped with the move, and parallel-run cutover while your store keeps selling.
Behavior-based product recommendations, semantic search that understands intent, dynamic pricing, AI product descriptions, and support chatbots — proven patterns from our 3 live AI products.
Inventory synced across channels, orders orchestrated to fulfillment, and shipping rates live at checkout — NetSuite, SAP, Odoo, QuickBooks, and carrier APIs unified.
From checkout-data discovery to phased sprints and rollout — a fixed-price process built around the truth that conversion, not code, is the goal.
We walk your actual funnel — browse to cart to checkout to fulfillment — and enumerate every system that must connect: payment gateways, ERP, inventory, shipping carriers. Honest build-vs-buy analysis included.
A written scope document: features, integration points, and a fixed-price proposal within 24 hours.
We design an API-first integration layer with per-system adapters — payment gateways, ERP connectors, inventory and shipping feeds — so each new channel is an adapter, not a rebuild.
An architecture document, data flow diagrams, and API contracts — in writing, before any development starts.
Prototypes validated against the abandonment data — one-tap checkout, thumb-first mobile flows, guest checkout by default, and exception-first order dashboards that surface problems, not noise.
Clickable prototypes signed off by the people who’ll actually shop and manage the store daily.
Two-week sprints with demos; integrations phased by revenue priority so checkout and catalog improvements ship while long-tail connections continue.
A staging build every sprint, direct engineer access, and weekly written progress reports.
Load testing at your peak-traffic volumes, payment-gateway validation, mobile checkout trials on real devices, and cart-recovery pilots before full rollout.
A test report and validated performance data your team can trust before go-live.
Parallel-run cutover — the old store keeps selling until the new one proves itself — then continuous optimization from real conversion data on a flexible retainer.
A live production store with monitoring dashboards, rollback plan, and your code, your accounts, zero lock-in.
Build a scalable eCommerce platform with the right tech stack—from Next.js, React, and Node.js to payments, inventory, and AI for a store that converts.
US-market eCommerce builds run $50K–$500K+, and checkout optimization is usually sold separately as CRO after launch. Our fixed prices below build it in from sprint one, contracted through our Delaware entity.
Conversion-first architecture, honest platform advice, mobile commerce expertise, and full code ownership — the substance behind every eCommerce build we ship.
We engineer against the abandonment data — transparent costs, guest flows, ~7-field checkouts, wallet payments — instead of launching a leaky funnel and selling you CRO to fix it later.
Platform, headless, or custom — decided by your catalog complexity, pricing logic, and volume economics, in writing. We build on Shopify happily and know exactly where its walls are.
US builds run $50K–$500K+. Our Delaware-contracted, Ahmedabad-engineered model delivers conversion-grade scope at a fraction — fixed price, fixed timeline.
1,200+ shipped apps mean your mobile experience is native-grade — one-tap wallets, push-driven recovery, thumb-first flows — exactly where abandonment is worst and opportunity biggest.
Three live AI products of our own mean semantic search, behavioral recommendations, and dynamic pricing arrive production-tested — with per-feature cost dashboards, not runaway API bills.
Repos with history, your cloud and payment accounts, and complete documentation — a clean asset whether you scale with us, hire in-house, or raise on the numbers.
From DTC brands and B2B wholesalers to marketplaces and subscription businesses — we build storefronts, checkout flows, and commerce platforms shaped around each segment’s buyer behavior.

From checkout conversion to headless replatforms — here’s what commerce teams say after choosing our eCommerce development company.
We needed audio/video calls for patient consultations, live streaming for health seminars, and an Instagram-style photo/video feed for our medical community. Primocys delivered every feature, production-ready and on schedule. Their deep understanding of healthcare workflows stood out — they didn’t just build features, they built the right experience. Patient engagement and retention have grown significantly since launch.
Primocys developed my mobile application from scratch, handling everything from initial design to final deployment. They managed the entire project, demonstrating great flexibility by incorporating all my feedback and retakes. Beyond development, they successfully guided me through the App Store and Google Play submission process and are currently managing the app’s ongoing maintenance.
Our B2B and B2C platform helps Nigerian manufacturers sell at wholesale prices and suppliers offer competitive retail pricing, with a strong focus on Made in Africa products and easy local and international distribution. The app has received excellent user reviews for its design and unique features. Communication with the Primocys team was smooth in an agile setup, even beyond office hours when needed. Their mobile app development expertise is excellent—highly professional and reliable.
We hired Primocys to develop a highly complex and specialized mobile application, and they delivered outstanding results.

Their technical skills, timely delivery, availability, and the personal attention Arpan Sagar brings to each project truly stand out. The team stays focused and committed from start to finish—an excellent experience overall.
The dating app was delivered successfully and approved by both Apple App Store and Google Play. Our users are highly impressed with the design, UI, and overall functionality. The project was well planned with clear milestones, and all modules were delivered on time. The team is talented, patient, and flexible, accommodating multiple scope revisions as requirements evolved.
