That is the work this page is about. Not brochure sites — those are covered under website design — but custom development: applications, portals, integrations, and builds where the requirement is specific enough that no off-the-shelf tool fits it without bending your process out of shape.
Custom Web Development for Chicago-Area Businesses
Most businesses do not need a developer until they hit the thing a website cannot do. A quoting process that lives in a spreadsheet. A portal customers keep asking for. Two systems that will not talk to each other, so somebody spends their morning copying rows between them.
Web development or website design?
The distinction matters because the two are priced, scoped and staffed differently, and because being sold one when you needed the other is a common and expensive mistake.
Website design is a marketing problem. The site exists to be found, to explain what you do and to produce enquiries, and it is judged on traffic and conversion. If what you need is a fast, well-structured site that ranks and converts, start there — it is the cheaper answer and usually the right one.
Web development is a workflow problem. There is something your business does, repeatedly and manually, that software should be doing instead — or something your customers want to do themselves that they currently have to phone you about. The deliverable is not pages. It is behaviour: logins, permissions, data moving between systems, calculations, state that persists.
Plenty of projects need both, and when they do we build them together rather than handing a site to one vendor and an application to another and letting them argue about the seam.
What we actually build
The projects differ, but they cluster into four kinds of work.
- Internal tools — quoting and estimating calculators, job and inventory tracking, dashboards that replace the spreadsheet everyone is afraid to touch
- Customer and partner portals — secure logins where people check orders, request quotes, pull documents or see pricing specific to their account
- Integrations — connecting a CRM, a payment processor, a calendar and an email platform so leads and orders flow automatically instead of being retyped
- Custom builds — sites with requirements a template cannot meet: large product catalogs, multi-location structures, branch-level content, data-driven pages generated from a source of record
Why custom, and when you should not go custom
Custom software is worth it when your process is genuinely yours and the off-the-shelf alternative would force you to change how you work to suit the tool. Distributors feel this most sharply — branch structures, contractor pricing tiers and manufacturer relationships rarely map onto a generic platform without compromise.
It is not worth it when a configured off-the-shelf product would do the job. If your requirement is a CRM, buy a CRM. If it is e-commerce with standard products and standard checkout, a platform will beat a custom build on cost, on time to launch and on everything you get free for the next decade without paying for it.
We will tell you which situation you are in before quoting. Talking a client out of a custom build costs us a project and saves them considerably more, and we would rather be the vendor who does that than the one who takes the work.
The stack, and why it is this one
Everything we build runs on Next.js, deployed on Vercel, with version control on every change through GitHub. That is the same foundation as our websites, which means one team maintains everything rather than a site team and an app team with different habits.
Next.js matters for a specific reason: it renders on the server, so an application built on it is fast and indexable rather than a blank page that fills in after the JavaScript loads. For anything customer-facing that needs to be found, that difference is the whole ballgame.
Version control matters for a less glamorous reason. Every change is recorded, attributable and reversible. When something breaks at four in the afternoon, the question is which change caused it and how fast it can be rolled back — and without version control neither question has an answer.
We do not build on a proprietary platform that only we can maintain. The code is standard, the repository is yours, and another competent developer could pick it up. Lock-in is good for agencies and bad for clients, and we would rather keep your business by being worth keeping.
Scoping, and the part most projects get wrong
The failure mode in custom development is not bad code. It is building the wrong thing accurately — software that does exactly what was specified and still does not fit how anyone works.
So we start with the process rather than the feature list. What happens today, step by step, including the steps people do not mention because they are so routine nobody thinks of them as steps. Where the friction actually is. Who touches the thing and what they each need from it. The first version of most requirements turns out to describe a workaround that exists because of an older constraint nobody has revisited.
Then we scope to a first release that is deliberately smaller than the eventual ambition — the smallest thing that removes real pain, in people's hands early, where the rest of the requirements get discovered under actual use rather than in a meeting room. A tool nobody adopts is a total loss regardless of how complete it was on launch day.
Consolidating what already exists
Not every development project starts from nothing. A common one, especially after an acquisition or a rebrand, is that a business is running two or three separate sites that each do part of the job and compete with each other for the same searches.
Splitting your presence across multiple domains splits everything that makes a site rank. Links, authority and content that should reinforce one destination are divided between several, and each one is weaker than the single site would have been.
A roofing and siding contractor in Illinois came to us running two separate company sites. We merged them into one and concentrated the search strength that had been divided, alongside paid search — over the following twelve months the combined programme produced 550+ leads and 100+ calls at roughly $63 a lead. The consolidation work is unglamorous and it is often the highest-leverage development project available.
After launch, which is when most of the life of the software happens
Software is not finished at launch; that is when it starts being used, and real use produces requirements no amount of planning surfaces. Budgeting as though the project ends on launch day is how applications quietly rot.
We stay on the build. The same team that wrote it handles fixes, changes and additions, which means nobody has to reverse-engineer intent from code before they can safely change a line. Dependencies get updated, because an application left alone for two years is a security problem rather than an asset.
You own the repository and the deployment throughout. If you ever want to take the project elsewhere, you can, and it will be in a state where somebody else can actually pick it up.
Why A&B
We build for contractors, distributors and local businesses rather than for startups, and that shapes the work. The people using what we build are often on a phone in a truck or at a counter with a customer waiting, not at a desk with two monitors and patience. Interfaces that assume otherwise do not get used.
Our team covers design, development and support across Chicago and Mexico City, with one point of contact on your side of it rather than a ticket queue. And because the same team runs the search and advertising work, a portal gets built in a way that does not accidentally wreck the rankings of the site it sits inside — a seam where separate vendors routinely cause damage neither of them notices.
What the engagement looks like.
Map the process
How the work happens today, including the steps nobody mentions. Where the friction actually is, and whether software is the right answer at all.
Scope a first release
The smallest build that removes real pain, with the rest sequenced behind it. Fixed scope, honest estimate, and a clear statement of what is not in version one.
Build and review
Working software in front of you as it goes, not a reveal at the end. Version control on every change, deployed previews you can click through before anything goes live.
Launch and keep building
Real use generates the next round of requirements. We stay on it — fixes, changes, dependency updates — rather than handing over a repository and disappearing.
Priced to the scope of the work.
Development is priced to scope after we have mapped the process — quoting custom software from a feature list is how projects end up costing double. If an off-the-shelf product would serve you better, we will say so before quoting.
What moves the number:
- Whether this is a new build, an integration, or consolidating existing systems
- How many user types need access, and what each is allowed to see
- Which systems have to be connected, and whether they have usable APIs
- Whether data needs migrating from what you run today
- How much ongoing change you expect after launch

What is the difference between web development and web design?
Design is a marketing problem — a site that gets found, explains what you do and produces enquiries. Development is a workflow problem — logins, data moving between systems, calculations, things your business does manually that software should do instead. If you need a site that ranks and converts, website design is the cheaper and usually correct answer. If people are retyping data between systems or asking for a portal, that is development.
How long does a custom build take?
It depends almost entirely on how many user types and integrations are involved, which is why we scope after mapping the process rather than from a feature list. What we can commit to is sequencing: a first release that solves the sharpest problem, in use early, with the rest built behind it — rather than a long build that lands all at once and turns out to fit nobody.
Do I own the code?
Yes. The repository is yours, the deployment is in your account, and the code is standard Next.js and TypeScript rather than a proprietary platform only we can maintain. If you ever move the project elsewhere, another competent developer can pick it up — which is the test that matters.
Can you integrate with the systems we already use?
Usually, and the deciding factor is whether the system exposes a usable API. Most modern CRMs, payment processors, calendars and email platforms do. Older or heavily customised on-premise software sometimes does not, and then the honest options are a different kind of integration or none at all. We check this during scoping rather than discovering it mid-build.
We have two websites from an acquisition. Should we merge them?
Almost always yes. Running separate sites splits the links, authority and content that should be reinforcing one destination, so each is weaker than the single site would have been. The merge needs doing carefully — redirect mapping, content consolidation, preserving what already ranks — but it is frequently the highest-return development work available.
What happens after launch?
We stay on it. The same team that built it handles fixes, changes and dependency updates, so nobody has to reverse-engineer the code before safely changing it. Applications left untouched for a couple of years become security liabilities rather than assets, and budgeting as though the project ends at launch is how that happens.
Is custom always better than off-the-shelf?
No, and we will tell you when it is not. If your requirement is a CRM, buy a CRM. If it is standard e-commerce, a platform beats a custom build on cost, launch time and everything you get free for the next decade. Custom earns its keep when your process is genuinely yours and a generic tool would force you to change how you work to suit it.
