Chicago Web Development Services

Here are typical market ranges of web development in Chicago, IL:

• Smaller projects (an integration, an automation, or improvements to an existing site): 2,000–10,000
• Substantial custom applications and platforms: 20,000–200,000 or more
• Enterprise systems: typically custom pricing

Where your project lands comes down to the number of features, integrations, user types, and the amount of testing involved. These are general market estimates. We’ll give you a specific price after discovery.

A single API integration or workflow automation can take a few weeks. A custom ecommerce platform, customer portal, or web application usually takes several months, and larger systems often launch in phases so you can use part of it while the rest is built.

Your existing data affects the schedule more than most people expect. If it’s spread across several systems or full of duplicates, cleaning it up adds time to any project that relies on it.

What’s the difference between a website, web application, and mobile app?

• A website: Presents information about your business, products, and services. Visitors mostly read and contact you.
• A web application: Lets people do things in a browser, like log in, manage an account, place orders, or use a dashboard. Nothing to download.
• A mobile app: Installed from the App Store or Google Play. It can use phone features like the camera, GPS, and push notifications.

For example, an HVAC company might use a website to attract new customers, a web application to let customers schedule and manage appointments, and a mobile app to give technicians access to job details in the field.

Your time goes mostly into the start and the finish, with short check-ins in between. Here’s where we’ll need you:

• Discovery and planning: Walk us through how your business runs and the software you use, then approve the scope and designs before development starts.
• Content and access: Logins for systems we’re connecting to, plus any copy, product data, or images your team has.
• Development reviews: A short look at working features at the end of each cycle, with feedback on anything that needs to change.
• Testing and launch: Someone on your team using the new site or app the way they would day-to-day before it goes live.
• Training: A walkthrough for the personnel who will manage it after launch.

Start with existing software if it already handles most of what you need. Custom development makes sense when your workflow is unusual, when your systems need to share data they can’t share today, or when no commercial product does what you need. Plenty of projects end up as a mix: an established platform like WordPress, Shopify, or Salesforce, with custom features and integrations where the off-the-shelf version falls short.

Sure. For a prototype or a simple brochure site, go for it. AI coding tools are fast and getting better.

The risk shows up once logins, payments, customer data, or connections to other systems are involved. AI-generated code often works in a demo and fails in ways nobody notices until a customer does: a missing permission check, a form that exposes data, an integration that quietly drops records. If real customers or real money will touch it, have a developer review it before launch.

AI does well with repetitive work that follows a pattern, such as:

• Capturing new leads, qualifying inquiries, and routing them to the right salesperson or department
• Automatically transferring information from forms, emails, or conversations into your CRM or other business systems
• Answering staff or customer questions from your own manuals, policies, and product documentation
• Extracting data from invoices, contracts, and other PDFs
• Categorizing support tickets and routing them to the right team
• Writing product descriptions or reports from data you already have
• Summarizing long records like project histories or case files

We’d keep it away from anything where a wrong answer is expensive and nobody’s checking, like pricing commitments or legal guidance. Those still need a person to review the output.

Usually, yes. Most modern software offers APIs or webhooks, which means your website or app can exchange information with CRMs like Salesforce, ERPs like Microsoft Dynamics, case management systems like MyCase, and accounting, scheduling, and inventory tools. Older systems without an API take more work, but there’s often still a way in, even if it’s a scheduled file export.

Yes, as long as it’s planned well (which it will be). We inventory everything first: pages, products, user accounts, records, and how they relate to each other. When we move it, we check it against the original and redirect every updated URL so you keep the sitemap and search rankings you’ve built.

Yes. We’ll review the existing code and hosting setup first and tell you whether it makes more sense to fix what’s there or rebuild. You’ll have that answer before you commit to either.

That comes down to how it’s built and maintained. The basics include encrypted connections, secure logins, permissions that limit who can see what, and protection against common attacks like SQL injection. Applications that handle payments or confidential client records need additional safeguards, and every application needs regular security updates after launch.

Yes. Illinois’ Personal Information Protection Act requires businesses to protect personal information and notify people after a data breach. The Information Privacy Act sets rules for collecting identifiers like fingerprints and facial geometry scans.

BIPA is especially important. Lawsuits under it have been expensive for Illinois companies, and it applies to more than you might expect, including employee time clocks that scan fingerprints. If your application will touch biometric data, talk to your attorney before launch. Federal and industry-specific rules may also apply depending on what you collect.

If your business is covered by the Americans with Disabilities Act, its online goods and services are expected to be accessible too. Accessibility lawsuits over websites are more common than you may expect. Illinois also has its own technology accessibility requirements for state agencies and public universities. In practice, that means keyboard navigation, screen reader support, usable forms, and enough color contrast. It’s far more affordable to build those in from the start than to retrofit them later.

The custom code we write and your content belong to you, and you’re free to take them to another developer whenever you want. Third-party plugins, frameworks, and licensed software stay under their own license terms. If you’re talking to other developers, ask this question before you sign anything.

Plan for hosting, software subscriptions, API usage fees, security updates, and maintenance. Custom applications also need occasional updates as browsers, operating systems, and the platforms they connect to change. A simple website might need little more than hosting and updates, while an app your operations depend on should have a support plan.

What do you need from us to get started?
For a first conversation, it helps to have:

• A rough description of what isn’t working or what you want to add
• A list of the software your team uses every day
• Any deadlines you’re working against
• A budget range (even a loose one)

If you don’t have all of that yet, we can work it out together during discovery.
