Custom Web Apps
When off-the-shelf tools don’t cut it we build what does
We build custom web applications, WordPress plugins, and business tools designed around how you actually work. Not how a software company thinks you should.
The problem
When off-the-shelf stops working
Most businesses start with off-the-shelf tools. And for a while, they work. You piece together a handful of SaaS subscriptions, a few plugins, maybe a spreadsheet or two.
But after a while, you start noticing some gaps.
Data lives in three different places and none of them talk to each other. You’re paying for five tools when one purpose-built app could replace them all. Your team spends hours on manual processes that should be automated. Or you need something that simply doesn’t exist yet.
Here’s when businesses typically come to us:
You’ve outgrown your current tools. What worked at $500K in revenue doesn’t work at $2M. The processes are more complex, the team is bigger, and the duct tape is showing.
You need systems to talk to each other. Your CRM doesn’t connect to your inventory. Your ordering system doesn’t sync with your accounting. Information gets entered twice, errors creep in, and someone’s always chasing down the “real” number.
You have a workflow that’s unique to your business. No SaaS product is going to nail it because no other business does it quite like you do. You need software that fits your process, not the other way around.
You want a competitive edge. The right custom tool doesn’t just save time. It gives you a capability your competitors don’t have.
WHAT WE Build
Custom apps & tools designed for your business
Every project starts with a business problem and ends with a tool that solves it. Here’s what that looks like in practice.
01
SaaS Applications and Platforms
Full web applications for your business or your customers. Whether it’s a tool you use internally or a product you sell, we handle the architecture, development, and deployment. Built to scale as your user base grows.
02
Internal Business Tools and Dashboards
The tools your team uses every day should make their jobs easier, not harder. Custom dashboards, reporting tools, and admin panels that surface the information that matters and hide what doesn’t.
03
Client Portals and Membership Platforms
Give your customers a place to log in, manage their accounts, access content, or interact with your business. We’ve built portals for everything from course platforms to service businesses that need a client-facing hub.
04
API Integrations and Data Connectors
Your tools should talk to each other. We build the connections between your existing systems so data flows automatically. No more manual exports, re-entry, or reconciliation spreadsheets.
05
Workflow Automation Tools
If your team does the same thing the same way every day, it should probably be automated. We build tools that handle the repetitive work so your team can focus on the work that actually needs a human.
06
Custom Calculators, Configurators, and Interactive Tools
Product configurators, pricing calculators, quoting tools, ROI estimators. Interactive tools that help your customers make decisions and help your sales team close faster.
07
Custom WordPress Plugins
We create high quality, custom WordPress apps that add valuable integrations and features to WordPress sites.
Our team can also provide development support for an existing commercial plugin to augment your development staff.
08
Custom Shopify Apps
Modern Shopify Apps that help you bridge the gap between various platforms and have less manual work running your store. Our apps are tailored to the way your store runs so you can save time and increase accuracy every day.
Use Cases
How we’ve helped businesses like yours
We’ve helped businesses of all sizes solve their unique problems with elegant technical solutions. We’ll take your ideal outcome and make it a reality with a custom-built app you can depend on.
Have a project in mind? Let’s talk about what’s possible.
A meal prep service needed a better way to handle orders.
They had come to dread fridays. New orders would come in so the kitchen was slammed. But Friday also meant that one or both partners would need to spend 4-7 hours on manual work like creating a spreadsheet from several different exports to manually modifying an InDesign template for meal labels.
We built them a custom Shopify app that fully automates their entire manual process. No more spending half the day in Excel, and no more weekend trips to print orders at the office with the correct date.
A vehicle wholesaler needed to sync Salesforce data to Shopify
They run their whole business through Salesforce and use it as the source of truth for their products. They had previously hired someone to build an integration with their Shopify store to sync product changes, but the Lambda function they used ended up costing the client over $10,000 in unexpected hosting bills because of a coding error.
We built them a new app that runs on hosting with predictable, low-cost billing and created a bespoke app that not only handled syncing, but gave them extra tools like deduping products and logging features. Their store now has product data that automatically updates whenever changes are made in Salesforce. And no chance of a huge surprise bill.
GenerateBlocks needed help realizing their grand vision
The GenerateBlocks team was working on their latest major release (version 2) and they needed some extra development help to bring the features to life. In addition to feature development and bug fixes, our team contributed directly to a number of well received and highly useful features, including the Query Block, Dynamic Tags, Style Indicators, and many of the custom Style controls.
These tools directly contributed to increased sales and improved user satisfaction as many of these features had been requested for a few years.
Our Process
How we’ll work together
We understand the problem before we start building. Here’s how that works.
Book a Call1
Discovery
We start by understanding your business, your goals, and what’s not working today. No assumptions. No jumping to solutions.
2
Strategy & Design
Before any code gets written, you see a clear plan: what we’re building, why, and what it costs. Then wireframes and design concepts you approve first.
3
Build
Designs become a working site in a real browser. You see progress as we go, not just static mockups.
4
Testing
We test forms, user flows, and edge cases before your customers see it.
5
Launch
When everything checks out, we launch your new site and ensure everything is working as it should.
6
Ongoing Support
We don’t disappear after launch. Updates, improvements, and support when you need it.

Common Questions
It depends on complexity, but most custom app projects start in the $10,000–$25,000 range. Simpler tools like calculators or basic integrations can be less. Full SaaS platforms or complex multi-system integrations will be more. We’ll give you a clear estimate after a discovery conversation so you know what you’re paying for before any work begins.
Smaller projects (a custom plugin, a calculator, a single integration) typically take 4–8 weeks. Larger apps and platforms can take 3–6 months. We’ll give you a realistic timeline upfront. If your deadline is aggressive, we’ll tell you rather than overpromise.
Yes. Many of our custom apps are built as WordPress plugins or integrated directly into existing WordPress sites. This keeps everything in one place, makes it easier to manage, and avoids the overhead of maintaining a separate platform.
Yes. We offer ongoing maintenance and support for everything we build. Software needs updates, bug fixes, and improvements over time. We plan for that from the start.
Our team works with PHP, NodeJS, React, and TypeScript. We are custom WordPress plugin and Shopify app specialists as well. For projects that need something different, we choose the stack that fits the problem not just the one we like the best. We’ll explain the technical choices in plain language so you can make informed decisions about your own business.
