Squarespace Website Development Services

Custom Squarespace builds that do more than look good.

Most Squarespace sites underperform not because of the platform, but because of how they were set up. We build Squarespace websites that load fast, convert visitors, and actually fit how your business runs, including the integrations, custom code, and structural decisions that templates alone cannot handle.

Squarespace Website Development for Your Business

A boutique fitness studio came to us after spending three months trying to get their Squarespace site to match their brand. The template kept fighting them. Their booking widget sat in the wrong place, their mobile nav was broken on older iPhones, and their product pages looked nothing like the mood board their designer had made. We rebuilt the site from scratch in Squarespace, used custom CSS and JavaScript to override the template's layout constraints, and connected their scheduling app directly through Squarespace's developer platform. The project took four weeks. Their first month after launch saw a 31% increase in online class bookings.

Squarespace is a legitimate platform for a wide range of business websites, from portfolios and service sites to e-commerce stores and membership portals. What it is not is a drag-and-drop tool that solves every problem without expertise. The platform has real limits, and knowing where those limits are before you start building saves you from redesigning the same page four times. We have been building on Squarespace since long before its 7.1 redesign, and we understand exactly where custom CSS and JavaScript fill the gaps that the native editor cannot.

We work entirely remotely with US businesses. Our team is based in Gandhinagar, India, which means we are deep in your project while you sleep. You share feedback at the end of your day and wake up to revisions already done. We have worked with companies across 20+ countries since 2015, and we sign an NDA and project contract before any work begins. Every line of code and every design asset we produce belongs to you.

Why Choose Squarespace Website Development

Pages That Load Under 2 Seconds

We optimize every Squarespace build for Core Web Vitals, compressing images, deferring non-critical scripts, and structuring content blocks to avoid layout shift. Slow pages cost you rankings and visitors.

Fixed Project Pricing

Every engagement is scoped and priced before we start. You know the total cost upfront, and there are no surprise invoices when a revision takes longer than expected.

Working Build in Weeks

Most Squarespace projects move from first call to live site in three to six weeks, depending on complexity. You see a functional draft before the final payment milestone.

Mobile That Actually Works

Squarespace's responsive behavior is helpful but not perfect. We test every build across real iOS and Android devices and write targeted CSS to fix anything the platform does not handle automatically.

You Own Everything

All custom code, design files, and configuration notes are handed over at project close. We do not hold your site hostage or require a retainer to keep it functional.

Integrations That Hold Up

We connect Squarespace to tools like Acuity Scheduling, Mailchimp, Stripe, and custom third-party APIs using Squarespace's native integrations and custom JavaScript where native options fall short.

Our Squarespace Website Development Services

New Website Design and Build

We design and build Squarespace websites from scratch, starting from your brand guidelines or building a visual identity alongside the site structure. The result is a site that looks intentional, not templated.

Template Customization

If you have a Squarespace template that is close but not quite right, we use custom CSS and JavaScript to close the gap. This is often faster and cheaper than a full rebuild.

Platform Migration to Squarespace

We migrate sites from WordPress, Wix, Webflow, and other platforms to Squarespace, preserving your URL structure, redirecting old paths, and rebuilding content without losing SEO equity.

E-Commerce Setup

We set up Squarespace Commerce stores with custom product page layouts, Stripe and PayPal connections, shipping rules, and tax configurations specific to your business model.

Squarespace App Integration

We integrate Squarespace Apps and third-party services, including scheduling tools, CRM connections, email platforms, and payment processors, so your site functions as part of your actual workflow.

Ongoing Maintenance and Updates

After launch, we offer monthly maintenance plans that cover content updates, plugin reviews, performance checks, and emergency fixes with a guaranteed 24-hour response window.

How We Deliver Squarespace Website Development Projects

No 47-slide proposal deck. No three-month discovery phase. Here is how a project moves from your idea to working software.

Start Your Project
1

Discovery & Planning

Before we open Squarespace's editor, we spend time understanding how your business actually runs. We ask about your sales process, your existing tools, your content workflow, and who manages the site after launch. That conversation shapes every structural decision that follows.

2

UI/UX Design

We design page layouts in Figma before touching the Squarespace build, so you can review the look and feel without being confused by platform limitations. Revisions happen at the design stage, which is faster and less expensive than rebuilding live pages.

3

Development

We build inside a Squarespace trial site so you can review the actual platform experience, not a static mockup. Custom CSS and JavaScript are documented in a separate file so future changes are straightforward for any developer.

4

Testing & QA

We test every page on Chrome, Safari, Firefox, and Edge, plus real iOS and Android devices. Forms, checkout flows, and any third-party integrations get tested end-to-end before we ever ask you to review the final build.

5

Launch

We handle domain connection, SSL verification, redirect setup, and a final performance check before going live. You approve the site on the staging URL and we flip the switch only after you confirm everything looks right.

6

Support & Growth

Post-launch support includes a 30-day warranty period covering any bugs or breakage at no extra cost. After that, monthly maintenance plans start at a flat monthly fee covering content updates, performance monitoring, and one round of minor edits per month.

Why Choose Aneri Developers

Your Project Moves While You Sleep

Our team is based in Gandhinagar, India, which means active development happens during US overnight hours. You end your day with feedback and open your inbox to progress. For most clients, this cuts overall project time by several days.

Same Engineers, Start to Finish

The person who reviews your requirements is the same person building your site. We do not hand projects off to a junior team after the sales call. You talk to the people doing the actual work.

Operating Since 2015

We have been building websites and software for over 11 years, with 500+ projects delivered across 20+ countries. Squarespace has changed significantly in that time, and we have stayed current through every platform update.

Communication That Does Not Drop Off

We run projects through Slack with daily written updates, Loom videos for design walkthroughs, and Zoom calls scheduled during US Eastern and Pacific business hours. Nothing falls into a communication black hole.

A Small Team That Stays Focused

We are a team of roughly 10 people, which means your project does not get queued behind 40 others. We take on a limited number of active projects at a time so each one gets real attention.

NDA and Contract Before Day One

We sign a non-disclosure agreement and a project contract before any work begins. Every custom code file, design asset, and configuration note transfers to you at project close. We keep no ownership over anything we build.

Frequently Asked Questions

Common questions about squarespace website development.

Squarespace works well for marketing sites, portfolios, e-commerce stores under a few thousand SKUs, and membership sites. Where it struggles is with highly custom application logic, large product catalogs with complex filtering, or sites that need deep database integrations. If your needs fall outside those boundaries, we will tell you directly and suggest a more appropriate platform rather than force a Squarespace build that will frustrate you later.

More than most people expect. Custom CSS handles layout overrides, font rendering, spacing inconsistencies, and mobile behavior that the built-in editor cannot touch. JavaScript extends this to dynamic behavior like conditional content display, scroll-triggered animations, and form logic. What it cannot do is add server-side functionality or replace a missing Squarespace feature entirely, so scope matters.

Yes, in most cases. Squarespace has native integrations for tools like Acuity Scheduling, Mailchimp, Google Workspace, and Stripe. For tools outside that list, we use Zapier connections or custom JavaScript to pass data where it needs to go. We scope integration requirements during discovery so there are no surprises about what is and is not possible on the platform.

We scope the project during a discovery call, document exactly what will be built, and give you a single price before any work starts. If you add something meaningful mid-project, we discuss scope and cost before building it. There are no hourly overages and no invoice surprises at the end.

A straightforward five to eight page site with standard integrations usually takes three to four weeks from kickoff to launch. More complex builds with custom e-commerce setups, migrations from another platform, or multiple third-party integrations typically run five to seven weeks. Timeline depends heavily on how quickly review feedback comes back from your side.

In practice, most clients find it works better than they expected. We use Slack for daily updates, Loom for walkthrough videos you can watch on your schedule, and Zoom for calls during US business hours. The time zone difference means development runs overnight relative to US time, so projects often move faster rather than slower.

Yes, and we make a point of building in a way that does not require a developer for routine edits. We document any custom code in plain language, record a short Loom walkthrough of the CMS for your content team, and structure pages so text and image updates are straightforward. If something later requires a developer, our maintenance plans cover that.

The first 30 days after launch are covered under a no-cost warranty. If a bug or breakage traces back to our build, we fix it at no charge. After the warranty period, we offer monthly maintenance plans with a 24-hour response commitment for urgent issues. We do not disappear after the invoice is paid.
