Not every money job is a calculation. Sometimes you need to check a figure, convert it, validate a document or keep a running record. Our tools sit alongside the TaxFly calculators to handle exactly those tasks — the small, repetitive jobs that eat into your day. Every tool is free, runs in your browser and is updated for the 2026/27 tax year.
Freelancers and small businesses use the Expense Tracker to log outgoings ahead of a Self Assessment return, the Quote Generator to send tidy client quotes, and the VAT Invoice Checker to make sure invoices meet HMRC requirements before they go out. The Currency Converter and Budget Planner round out the everyday essentials.
Built around how you actually work
Each tool is designed to do one job well, with no clutter and no learning curve. We never store the information you enter — everything stays on your device unless you choose to export it. The list keeps growing, and the panel above shows the bigger tools we are building next, including bookkeeping, landlord management and Making Tax Digital (MTD) filing. If there is a tool you would find useful, let us know and we will add it to the roadmap.
