01The approach
Custom is what you choose when the platform has become the constraint.
What you get
Think calculators pulling live rates, or research gated against your CRM. Content matched to account tier belongs here too.
These are not plugin problems. Pretending otherwise is how a site ends up with six plugins doing one job badly. Custom also ends the wait for someone else’s roadmap.
The shape is consistent. Next.js on the front, TypeScript throughout, and a headless CMS behind it. Edge rendering keeps load times near one second across three continents.
What this means for you.

Every engagement opens with an assessment that maps each requirement to where it belongs.

03Process
Five stages, starting with an architecture plan you sign off.
Requirements before architecture. A capability review of what the site has to do, mapped against what WordPress or Webflow can reach. You get a written architecture recommendation and a scope you sign off before design starts.
States, not just screens. One recommended direction with the routes we rejected, then design covering what interactive sites actually hit: loading, empty, error, permission-denied and partial-data states. The states are where custom projects usually come apart.
Front end, CMS and logic. Next.js build in TypeScript, with headless CMS schemas and previews wired. Business logic is written with tests. The deployment pipeline gives every branch its own preview URL.
Ship behind a flag. Content migration, 301 mapping, load testing against your peak, staged rollout behind feature flags and analytics verified live. Seven days on call afterwards.
Then it is genuinely yours. An optional retainer for feature work, dependency upgrades and monitoring. Or a full handover to your engineers, with architecture notes and a walkthrough. Both are normal endings here.
Stage 02 · Design
04Included
Sanity or similar, with schemas and previews set up. Marketing edits as easily as in WordPress.
Calculators, configurators, gated flows and live data in typed code. Real loading, error and empty states.
Pages are rendered close to the visitor. That is what keeps load times near one second worldwide.
HubSpot, Salesforce or your own APIs. Wired with retries, timeouts and alerting.
Playwright coverage on the flows that carry revenue. Preview deployments run on every branch.
Conventional patterns, written notes and repository access from commit one. Your engineers can take it over.
05Results
Live client stores, each measured against a number that was agreed before the work started.
Sales
A smart batting tee and coaching app for baseball and softball hitters, from youth players to pros. The brief was Japanese retro-cyberpunk, all neon, scanlines and chromatic edges, on a store that still opens instantly on a phone.
+35% Order value
Conversion
Swing-mechanics and vision trainers built by players for players: strobe glasses, reaction lights, swing locks. A deliberately minimal storefront that puts the product demonstration first and gets out of its way.
+56% Organic traffic
Conversion, from 1.5%
Bamboo swaddles, sleep bags and everyday babywear for Indian parents, much of it bought for infants with eczema. Hundreds of products, tens of thousands of orders and years of ranking history moved off a slow WooCommerce build without losing any of it.
+30% Organic traffic
Organic traffic
Farm-to-market kratom and kava from a family-owned Southeast Asian farm, sold to a US audience that reads labels closely. Six years of SEO equity, hundreds of products and thousands of pages moved off WooCommerce with every ranking intact.
+45% Conversion
Direct revenue
Stress balls, journals and planners for people managing their own mental load. An established Amazon seller that wanted a direct channel of its own: catalogue ported across, multi-market listings configured, conversion designed for.
No.1 Channel, ahead of Amazon
Sales
Handwoven jamdani turned into contemporary womenswear by a Kolkata label that refuses to greenwash. The store already existed; what it lacked was a path from admiring the craft to buying it.

09FAQ
What to ask before committing to a custom build.
Still unsure?
Ask us anything before committing to a call. Most questions get a real answer within a few hours.
hello@syscodes.inWhen the site has to behave like software. Think calculators, gated content and live data. Custom website development also earns its place when the site must meet a rule no CMS can.
A Next.js website development project with a headless CMS runs eight to fourteen weeks. Web apps with logins and dashboards take twelve to twenty. A rebuild on a modern stack is six to ten.
Yes. A headless CMS website is as easy to edit as WordPress. Live previews are set up for every template. The difference is where the logic sits. It lives in tested code, not a plugin screen.
Upgrades, monitoring and a small amount of feature work. We hand over a plan in writing at launch. You can run it with your own team or keep us on a retainer.
Yes, and we keep that route open. Content lives in a headless CMS rather than in code. Moving it is an export, not a rebuild.
The number of distinct user roles, how much of the logic is genuinely new rather than standard create-read-update-delete, and what it has to integrate with. Anything touching payments, permissions or reporting carries testing that is easy to underestimate at quoting time.
Yes. We have delivered in 20+ countries across five continents, and we commit to four guaranteed overlap hours with US Eastern (18:30–22:30 IST), with a full overlap for the UK and Europe. The names are in the contract.
