📌 No jobs, customers or invoices to track?

Then this is genuinely all you need to do. Plenty of sole traders never touch the jobs, customers or invoicing side of Debbie at all, market and stall traders, app developers, delivery and gig drivers, DJs, musicians and video editors, artists and content creators, influencers and streamers among them. Upload your bank statement, set your tax preferences once and that is the whole job.

Common Questions

The things people ask us most.

How much does Debbie cost?

£10 a month for one business (Solo), £17 for two (Duo) or £25 for three (Triple). Pay yearly on any of them and you save the equivalent of 3 months. Your first month is free, no card needed. No contract, cancel any time.

Who is Debbie for?

UK sole traders doing their own tax: delivery and gig drivers, content creators, online and market sellers, landlords and tradespeople. For landlords, Debbie works out your SA105 property figures, Section 24 mortgage interest relief and Rent a Room relief and tracks tenancies, rent and void periods. A property counts as one of your business slots, so a landlord who is also a tradesperson can run both from one Duo or Triple account.

When does Making Tax Digital affect me?

Most people do not need Making Tax Digital yet. If that is you, nothing changes. Keep using Debbie for your records and tax estimate, then download your Tax Return Pack to file it yourself or have someone file it for you. Making Tax Digital only starts once your money in from self employment and property, added together before costs, goes over a limit. HMRC calls this your qualifying income. The limit is £50,000 from April 2026, £30,000 from April 2027 and £20,000 from April 2028. HMRC looks at your tax return from two years before. If it does apply to you, Debbie now connects to HMRC and sends your quarterly updates (a short summary every three months) and your end of year return for you, only after you check the figures and tap to confirm.

Do I still need to pay someone to do my tax return if I use Debbie?

You do not have to have one. Debbie keeps your records, sorts your costs into the categories HMRC uses on the tax return and works out your tax for you. Plenty of people do their own tax return this way. If someone else files for you, Debbie makes them a Tax Return Pack with all your figures in one tap.

I'm not in the UK. Can I still use Debbie?

Yes. Debbie runs your whole business admin anywhere in the world: quotes, jobs, invoices, materials, expenses and profit per job. The one UK-only part is UK Making Tax Digital filing. Wherever you are, you can export your income and expense figures ready to hand to your own tax adviser or tax authority. Same £10 a month.

What does Debbie cost outside the UK?

£10 a month. Outside the UK, Stripe sells it to you and works out any tax your country charges. Your bank converts it to your currency at its usual rate.

Can I send quotes and invoices from my van?

Yes, that is exactly what Debbie is built for. You can create a professional PDF quote or invoice and email it to your customer before you have even driven away. Debbie generates the PDF and sends the email for you.

Does Debbie work on iPhone and Android?

Yes. Debbie is a Progressive Web App (PWA) that works on any smartphone: iPhone, Android or any device with a browser. You add it to your home screen like a normal app. No app store download needed.

Does Debbie handle CIS jobs?

Yes. Debbie includes a dedicated CIS job type for subcontractors who have tax deducted before they are paid. Your CIS invoices are tracked separately so your quarterly MTD reports stay accurate.

Does Debbie send my Making Tax Digital updates to HMRC?

Yes. Debbie now connects to HMRC and sends your Making Tax Digital quarterly updates and end of year return, only after you check the figures and confirm. You connect your HMRC account once in Settings and nothing is ever sent on its own. Most people do not need Making Tax Digital yet. If that is you, keep using Debbie for your records and tax estimate, then download your Tax Return Pack to file it yourself or have someone file it for you.

A note from the founder

"I always wanted to start my own business but filing taxes and the cost of paying someone to do it was a real fear for me. I built Debbie to solve that for myself first and I use it every day for my own businesses. That means I spot problems and sort them as soon as I find them and build genuinely helpful features."

James, Debbie Founder

What a trades software reviewer found

“All 8 lines in our test statement were categorised correctly with zero manual corrections needed … The resulting profit and loss figures reconciled exactly once checked by hand.”

“Every single one, across two separate rounds of testing weeks apart, was fixed the same day it was flagged, which is a genuinely rare turnaround for a one-person team.”
