Invoicing app for tradesmen: what a good one does (and what your invoice must show)
What to look for in an invoicing app as a UK tradesman, what every invoice must include, and where VAT, Making Tax Digital and payment terms come in.
A good invoicing app for a tradesman does three things without being asked: it raises the invoice the moment the job's done, puts a one-tap way to pay in front of the customer, and keeps every invoice tied to the job and the customer so nothing slips. Before you pick one, check two more things: that it produces an invoice with everything the law expects, and that it fits how you handle VAT and your tax return. Here's the checklist.
What every UK invoice must include
According to the government's guidance, your invoice must show:
- a unique identification number
- your company name, address and contact information
- the company name and address of the customer you're invoicing
- a clear description of what you're charging for
- the date the work was done (the supply date) and the date of the invoice
- the amount being charged, VAT if applicable, and the total owed
Sole traders must also show their name and any business name, and, if they use a business name, an address where legal documents can be delivered. Limited companies must use the full company name as it appears on the certificate of incorporation.
VAT: know which side of the line you're on
You must register for VAT if your taxable turnover for the last 12 months goes over £90,000, or you expect it to in the next 30 days. Once you're registered, invoices to other VAT-registered businesses must be VAT invoices, which carry more detail than ordinary ones. If you're registered, check that any invoicing app shows VAT the way your accountant needs it before you commit.
Making Tax Digital: what changes for sole traders
Making Tax Digital for Income Tax is arriving in stages for sole traders and landlords. If your qualifying income was over £50,000 in the 2024 to 2025 tax year, you should have started using it from 6 April 2026; over £30,000 in 2025 to 2026 means from 6 April 2027; over £20,000 in 2026 to 2027 means from 6 April 2028 (gov.uk). You'll need software that works with MTD to keep digital records and send quarterly updates, so check whether your invoicing app does that itself or feeds the bookkeeping software you or your accountant use.
Payment terms, and what the law says about late payers
Put your terms on the quote and on the invoice. For business customers, if you haven't agreed a payment date, the law treats payment as late 30 days after the customer gets the invoice (or after you do the work, if that's later), and you can claim statutory interest of 8% plus the Bank of England base rate (gov.uk). That applies between businesses, not to householders, which is one more reason to make paying easy.
What to look for in the app itself
- Invoice from the job, not from scratch. If the price is on the job, finishing the job should produce the invoice. Re-typing is where errors and delays creep in.
- A pay button, not just bank details. A hosted card page the customer can pay on in a minute beats a sort code in a PDF footer.
- Money straight into your account. Check whether payments land in your own account or sit with the software company first.
- A bank-transfer option for customers who won't pay by card.
- Proof next to the bill. For visible work, photos of the finished job answer "what am I paying for?" before it's asked.
- Reminders and accounting sync, if your business needs them. Check, rather than assume.
Send the invoice while the customer can still see the finished job, not a week later when they've forgotten what it looked like before.
Where Elivium fits, and where it doesn't
Elivium isn't standalone invoicing software; invoicing is one part of a job management app for trades. When a crew marks a visit complete, the invoice is raised from the job's price automatically, once. With card payments, it's a numbered Stripe invoice in your Stripe account, with a hosted pay page and 14-day terms, and each customer's portal page, in your name and colours, shows what they owe with a Pay now button. If you'd rather not take cards, bank-transfer mode records what's owed and prefills an email with your bank details, and you mark it paid when the money arrives. Either way you send the email from your own inbox, and on Pro you can send the before-and-after job report link with it so the customer sees exactly what the money was for.
What it doesn't do yet, plainly. Bank-transfer mode sends a payment request, not a full invoice document, so you'd issue the invoice itself from your own template. Card invoices don't yet show the customer's address or a separate supply date, so check them against the list above. Invoices carry a single job price with no separate VAT line, there's no Xero, Sage or QuickBooks sync, it isn't Making Tax Digital software, and it doesn't send automatic payment reminders. If you need accounting sync or MTD support today, a tool such as Tradify (from £34 per user per month, with Xero, Sage and QuickBooks Online sync on every plan) or Powered Now (from £28 a month for one user excluding VAT, which says it is HMRC-recognised for MTD) may suit you better. Both prices are from their own sites, as of October 2026. Whichever you shortlist, if you're VAT-registered, check how it shows VAT before you commit.
If invoicing tied to finished jobs and visible proof is what you're after, Elivium is £18/seat on Core and £32/seat on Pro with the photo reports. Self-serve sign-up isn't open yet; the live demo is the real portal with sample data, the pricing page has the full breakdown, and if you'd like to be one of the first firms on it, email us.

Common questions
What is the best invoicing app for tradesmen in the UK?
The best one raises the invoice when the job is done, gives the customer a one-tap way to pay, and fits your VAT and tax set-up. If you need accounting sync or Making Tax Digital support today, choose a tool that offers them. If you want invoicing tied to job completion and before-and-after proof of the work, Elivium does that on Pro at £32/seat (Core, at £18/seat, has the invoicing without the photo reports), though it has no separate VAT line or accounting sync yet.
What must a UK invoice include?
According to gov.uk: a unique identification number; your business name, address and contact details; the customer's name and address; a clear description of what you are charging for; the supply date and the invoice date; the amount charged, VAT if applicable, and the total owed. Sole traders and limited companies have a few extra requirements.
When do I have to register for VAT?
You must register if your taxable turnover for the last 12 months goes over £90,000, or you expect it to go over £90,000 in the next 30 days. You can register voluntarily below that.
Can my customers pay my invoices by card?
In Elivium, yes: invoices go through your own Stripe account with a hosted pay page, so card payments land in your account. If you would rather not take cards, bank-transfer mode sends your bank details in a payment request email instead, and you mark each one paid when the money arrives.
