Highlights

Keep your books straight and sail through Self Assessment — without a monthly
software bill. Sole Trader Accounts Boss is a simple, private app for the UK
self-employed: log your income and expenses, see your real profit, and get your
figures ready for HMRC. It runs entirely in your browser — open the file and
you're working. No account, no cloud, no subscription.

Unlike a fiddly spreadsheet, this is a proper interactive app that does the maths
for you and sorts everything into the right HMRC categories automatically.

★ WHAT IT DOES
• Income & expenses on a cash basis (counts when money changes hands — how most
sole traders do it)
• Expenses sorted into the real HMRC Self-Assessment (SA103) categories
• VEHICLES your way, per vehicle — pick the method that saves you the most:
– Simplified mileage: 45p per mile for the first 10,000 business miles, then
25p (motorcycles 24p, bicycles 20p, passengers +5p) — the threshold is
tracked for you across the whole tax year, OR
– Actual running costs: fuel, LEASE / finance, insurance, road tax, repairs
× your business-use % — often better for a leased or pricey vehicle
• Light invoicing — track open / paid / overdue; mark paid and it becomes income
• Real-time Profit & Loss, by UK tax year (6 April – 5 April), multiple years
• Self Assessment page — your figures mapped to the SA103 box numbers, ready to
copy to your return or hand to your accountant
• Optional, clearly-flagged rough tax + NI set-aside guide (switch off any time)
• CSV export + printable reports
• Backup & restore between phone and PC
• 100% offline & private — nothing is uploaded, your data stays on your device
• ONE PAYMENT — no account, no cloud, NO SUBSCRIPTION

★ PERFECT FOR
UK sole traders, freelancers, tradespeople, consultants, makers and Etsy sellers,
mobile workers, couriers — anyone self-employed who does their own Self Assessment
and wants simple, honest bookkeeping without the monthly fees.

★ WORKS ON ANYTHING
One file that opens in any modern browser (Chrome, Edge, Safari, Firefox) on
phone, tablet, laptop or PC. On a phone use "Add to Home Screen" to run it like
an app. No install, no login.

★ INSTANT DOWNLOAD — you receive
• Sole-Trader-Accounts-Boss.html (the app)
• START-HERE.pdf (quick-start guide)
• README.txt and LICENCE.txt

Please note: this is a record-keeping aid, not tax or accounting advice. HMRC
rates and rules can change — always confirm figures with HMRC or your accountant.
Digital product, so no returns — but message me if you need any help.

TIP: pairs perfectly with our UK Company Tracker and Mileage Log Boss.
