Custom internal tools for small businesses

When the spreadsheets break, the SaaS bills pile up, and your team is wasting hours on double-entry, that's the signal you need a real tool. I design and build internal systems that fit how your business actually works, then hand them off so they don't trap you with one developer or one vendor.

What I usually build

Internal tools come in many shapes. The pattern is the same: replace manual work or fragmented SaaS with one place your team can rely on. Common shapes I've shipped:

Booking & scheduling
Appointment booking, room scheduling, shift planning. With reminders, cancellation handling, and reporting. Not a calendar pinned to a fridge.
Time tracking & invoicing
Hours logged in one tool, approval flows for managers, export-ready by default for payroll and clients.
Order & inventory tools
Track orders, stock levels, suppliers, and customer history. Tie in your accounting export so nothing falls between systems.
Customer portals
Self-service for your clients to upload, download, message, or book. Reduce the email back-and-forth.
Admin dashboards
Operations cockpits that pull from the systems you already use (CRMs, spreadsheets, payment platforms) into one screen.
Office add-ins
Bring live data into the tools your team already lives in: Excel, Outlook, Teams. No retraining.

Recent projects

Three I can talk about openly. Each replaced a real, messy process with a tool the team still uses.

Dialogue Time: Time Tracking & Planning Portal

Replaced scattered timesheets and manual payroll with one source of truth. Consultants log hours, managers approve in real-time, exports are audit-ready.

NFC Lunch: Tap-to-Buy Canteen System

Replaced cash at the company canteen with NFC tap-to-buy. Each employee gets a tap-and-go card and a monthly statement.

Project Status Excel Add-in

An Office add-in that pulls live utilisation and schedule data into Excel so PMs stop maintaining parallel sheets.

How an engagement works

1. Discovery
A few short conversations and a walkthrough of how you work today. Output: a scoped plan with phases, trade-offs, and a fixed first-phase price.
2. Design
Wireframes for the screens that matter. We agree on the data model and the user flows before any code is written.
3. Build
I work in short cycles with regular demos so you see progress and can redirect early. No black box.
4. Handoff
Code, deployment config, docs, and a recorded walkthrough. You own everything. If you change developer later, the next person can pick it up.

Stack & approach

I pick boring, well-supported technology over fashionable ones. The goal is a system your next developer can read and extend without a six-month ramp-up.

Backend

Django or Node.js with Postgres. Type-safe APIs, audit-friendly history, authentication that actually works for non-engineers.

Frontend

Next.js + TypeScript + Tailwind. Server-rendered for speed and SEO, accessible by default, no SPA bloat.

Hosting

Dockerised and deployed on a VPS or a Dokploy/Coolify host you control. No vendor lock-in. Daily backups, HTTPS, monitoring out of the box.

Tell me where the spreadsheet is breaking, who's using it, and what good looks like. I'll come back with a phased plan and an honest first-step quote.
