About Us

Built by a developer frustrated with expensive, bloated expense trackers.

Drowning in Receipts

I needed a way to track my business expenses without relying on third-party cloud applications. The existing options were either expensive subscription services, bloated with features I'd never use, or simply not intuitive enough for someone who just wanted to get the job done.

Every month, I'd face the same pile of invoices from suppliers, contractor bills, software subscriptions, and travel expenses. The thought of manually typing each one into a spreadsheet or accounting software felt soul-crushing. The cloud-based expense trackers promised to help, but they came with high monthly fees, required me to trust another company with my financial data, and often forced me to navigate through dozens of features I'd never touch.

I didn't need project management integrations, team collaboration tools, or automated workflows. I needed something simple: upload an invoice, extract the details automatically, record it, and move on. That's it.

Simple Doesn't Mean Manual

What I really wanted was visibility. How much was I spending each month? Which categories were eating my budget? Which vendors was I using most? Having that information meant staying on top of my finances and making tax returns far less painful.

I didn't want to spend hours each month wrestling with spreadsheets or complex accounting software just to answer those basic questions. Then AI technologies became powerful enough to actually read invoices accurately - not just extract text, but understand what the text meant in context. Line items, tax calculations, vendor details, all parsed correctly.

I realised I could build exactly what I needed: a Mac app that used AI to handle the tedious extraction work, gave me the spending insights I was after, and didn't force me to become an accountant in the process. Simple tools for simple needs.

AI-Powered Expense Management

BillKit is the result of scratching my own itch. It does one thing well: takes your invoice files and automatically extracts the vendor, amount, date, and other details using AI. No typing, no complexity, no feature creep. You get a clear view of your spending by month, category, and vendor - everything you need for staying organised and handling tax time without the stress.

The interface is straightforward because I designed it for someone who just wants to get in, process their invoices, and get back to actual work. No learning curve, no manual to read, no training required. Upload an invoice, review what the AI extracted, approve it, done.

I built it for myself first, making decisions based on what I actually needed rather than what looked impressive on a features list. The Free tier gives you everything to get started, and BillKit Pro scales with you when you need more.

Common Questions

We've got you covered. Quick answers to help you get started.

What is BillKit?

BillKit is AI-supported expense tracking software for macOS that automatically extracts data from your invoice files. Instead of manually typing vendor names, amounts, and dates, you simply upload PDFs or photos and let AI do the heavy lifting.

It's designed for freelancers, sole traders, and small business owners who need efficient expense management without the complexity of enterprise accounting software.

What do I need to get started?

You'll need a Mac running macOS 14.6+ (Sonoma) or later, about 500MB of free disk space. While you can add expenses manually, you'll need an API key from either Claude (Anthropic) or OpenAI to use AI powered invoice data extraction features.

Both providers offer free credits when you sign up, so you can test BillKit's AI invoice processing without any upfront costs. Setup takes about 5 minutes.

How much does BillKit cost?

BillKit's Free tier is genuinely free forever - no credit card required, no surprise charges, no trial period that expires. You get 1 business, 10 vendors, 5 categories, and 25 expenses per month.

Great for freelancers and small business owners. When you need more capacity, BillKit Pro offers unlimited everything with monthly billing at £2.99 per month.

Can BillKit process multiple invoices?

Yes! Upload multiple files to BillKit's queue and process them all at once OR one by one - your choice! Perfect for month-end bookkeeping sessions when you have a stack of invoices waiting.

Just drag and drop all your files, and let AI work through the batch. You'll see them get processed in real-time. If any fail, you can retry them again anytime.

How much does AI processing cost?

AI processing is pay-as-you-go through your provider (Claude or OpenAI). Each invoice typically costs £0.01-£0.02 to process, depending on file size, number of invoice pages in the file and it's complexity.

For 50 invoices per month, expect £0.50-£1.00. Both providers offer free credits when you sign up, giving you plenty of runway to test BillKit before paying anything.

Does BillKit integrate with Xero or QuickBooks?

Not directly, but BillKit exports all your data to CSV and JSON formats that accounting software can import. Export your expenses, categories, and vendors with all details and import the files into any accounting platform that accepts CSV formats.

Due to the number of accounting platforms globally, you may need to map the columns to match your accounting software's import requirements manually.

What reporting does BillKit have?

BillKit's dashboard shows spending trends over time, top categories by amount, top vendors by spend, and recent activity. Filter by date range (last 7 days, fiscal year, custom periods) and currency to analyse exactly what you need.

For deeper analysis, you can export all your data to CSV or JSON and create custom reports in Excel or Google Sheets.

Does BillKit store data in the cloud?

No. BillKit is a fully local macOS application. Everything stays on your Mac: the database, invoice files, categories, vendors, and settings.

This gives you complete control and eliminates concerns about data breaches, third-party access, or subscription-dependent data access. Your data is yours, period.
