ai for business
Cut the busywork with AI
Routine accounting and back-office tasks, drafting replies, rethinking repetitive work. We reshape the work you repeat every day so AI can take it on.
Automate back-office work
Draft routine processing — invoices, expenses, reconciling payments — with AI, leaving people to just check it.
Spot the repetitive work
We map the tasks you repeat each day and week, and carve out the parts AI can take on.
Draft replies and documents
Draft email replies, routine reports and documents with AI, skipping the from-scratch effort.
Quoted individually to fit the work. Start with a free consultation.
why onbit
Three ways we make the day-to-day lighter
Updates, handled
Post news, closures and availability yourself from an admin screen. No time to write? We cover news drafts and small edits within the monthly fee.
Admin, handed to AI
Entering accounts, replying to enquiries, repetitive manual work. We reshape the tasks you repeat each day so AI can take them on.
Fast, and rarely down
Built with Astro and Cloudflare: pages load in under a second, with minimal risk of the server going down. The monthly fee also covers uptime monitoring and small fixes.

Details →01 Talk
First, we listen
It's fine if much is still undecided. Tell us what's getting in the way and what you want to do. 30 minutes, online, free.
02 Proposal
We send a plan and an estimate
Page structure, design direction, an estimate and a schedule, all on one sheet. No jargon. We start building only once you're happy with it.
03 Build
We build the pages one by one
Depending on the plan, building takes 1 to 4 weeks. You can check progress any time on a preview URL (a staging page before launch). We report progress once a week.
04 Review
You review the whole site on a preview URL
Just before launch, you go through everything on a preview URL. Text, photos, colors, layout — we revise anything you want changed. We don't go live until you're satisfied.
05 Launch
Launch
We handle the domain setup, SSL (encrypted connection) and the operations manual. All you see is the URL of the finished live site.
06 Support
We keep working on it every month
Launch isn't the end. Within the monthly fee we swap text, add photos and make small improvements. The price stays the same — a year later, or five years later.
our story
It started with a music school
Taking on the back-office work for a music school made one thing clear: teaching and keeping a school running are two different jobs.
People who teach, host or treat clients want their time for their craft — yet news posts, bookings, enquiries and daily admin keep piling up. Onbit takes that back-office work off your plate from two sides: your website, and AI that handles the work itself.

behind the build
Why a monthly plan works.
Onbit uses an AI coding assistant (Claude Code) to speed up the build.
Design decisions, talking with clients and the final code check are all done by a person.
Speed is the AI's job; quality is the person's job. We split the roles.
