NexaFlow builds custom web apps for small businesses: booking portals, customer apps, job and lead dashboards, and AI tools like chat assistants. You email your idea, get a free written plan with a fixed quote, and see a working demo link every week while it is built.
Apps that save you time and win you customers
No bloated software you have to work around. Just the tool your business needs, with the features you asked for.
Booking & customer portals
Let customers book a visit, request a quote, check job status or pay online, from a web page with your name and logo on it.
Mobile-friendly apps (PWA)
Simple apps that open from a link and can be added to a phone's home screen. Works on iPhone and Android without an app store.
Internal tools & dashboards
Job tracking, lead dashboards, crew schedules or a simple admin panel, so your team stops juggling spreadsheets and sticky notes.
AI features
Chatbots that answer customer questions, AI assistants for your team, and tools that read, sort, summarize or write documents and text.
Integrations
Connect the new app to the tools you already use, like your calendar, email, Google Sheets, CRM or accounting software.
Not sure what you need?
Just describe the problem in plain words. We'll suggest the simplest thing that fixes it, even if that's not a full app.
From idea to launch, all by email
No calls or meetings needed. You always know what's being built, what it costs, and what comes next.
Send your idea
Email us what you want the app to do, who will use it and any tools it should work with. Rough notes are fine.
Get a written plan
We send back a free written plan: the features, the milestones and a fixed quote. You decide after reading it.
Weekly demo links
We build in weekly milestones. Each week you get a link to try the latest version and reply with feedback.
Launch & support
We help you go live, fix anything that comes up, and keep improving the app when you need more.
Fixed quote after a free written plan.
Every app is different, so we don't guess a price up front. Once we understand your idea, the written plan lists exactly what we'll build and what it costs. You know the full price before any work starts.

Questions about custom apps
How much does a custom app cost?
Every project gets a fixed quote after a free written plan. The price depends on what the app needs to do, and you see the full price before any work starts.
How long does it take to build?
It depends on the size of the app. Your written plan lists each milestone, and you get a demo link to try every week while we build.
Do I need to get on a call or attend meetings?
No. Everything happens by email. You send your idea, read the plan, and reply to the weekly demo links with your feedback.
What happens after the app launches?
We help you go live, fix any issues that come up, and can keep improving the app as your business grows. The support details are written into your plan.
