A UK invoice app is for producing a client-ready bill that identifies both parties, explains the charge, states the relevant dates, and shows the amount owed. The document needs a unique invoice ID, supplier company name, address and contact information, customer company name and address, a clear description of the goods or services, the supply date, the invoice date, the amount charged, VAT where applicable, and the total owed.
Business identity matters before totals appear. A sole trader invoice must show the trader's name and any business name used. A limited company invoice must show the full company name as it appears on the certificate of incorporation. Those details reduce payment delays because the buyer can match the invoice to a supplier record, tax record, purchase order, or contract without asking for a corrected version.
The UK indirect-tax regime is VAT. VAT-registered businesses must charge VAT on taxable goods and services unless the supply is exempt, and VAT invoices must show the supplier's VAT number with VAT displayed separately. The registration threshold is £90,000 when taxable turnover for the last 12 months goes over that amount or is expected to exceed it in the next 30 days. Voluntary registration is allowed below the threshold.
A full VAT invoice needs a sequential unique number, tax point, issue date if different, supplier name, address and VAT registration number, customer name and address, description, quantity or extent, unit price, VAT rate, VAT-exclusive amounts, any discount rate, and total VAT in sterling. The standard VAT rate is 20% for most goods and services, with 5% reduced and 0% zero-rated treatment for qualifying supplies.
A useful UK invoice app lets you set payment terms, tax treatment, currency, and invoice numbering before you send the document. Businesses can set their own payment terms. Without an agreed payment date, payment is due 30 days after the invoice or the delivery or service date. For business-to-business transactions, statutory late-payment interest is 8% plus the Bank of England base rate unless a contract sets a different rate.
Electronic VAT invoices are allowed in the United Kingdom, but they are optional. You do not notify HMRC before using them. The electronic version must contain the same information as a paper invoice, and the process must preserve authenticity of origin, integrity of data, legibility, and customer agreement. VAT invoice amounts can use any currency, but total VAT chargeable must be shown in sterling.
A free invoice app is enough when you need a single compliant invoice, have the source numbers ready, and can manually check VAT treatment, payment terms, and client details. It works for a one-off project, a small service job, or a client that only needs a PDF. Keep a copy with supporting records so the invoice number, tax point, and amount trail stay clear.
A managed workflow becomes necessary when billable time, non-billable work, expenses, rates, approvals, and repeat client settings feed invoices every month. Everhour supports project billing status, task-level non-billable controls, custom task rates, member-rate exceptions, and admin reports for billable time, non-billable time, billable amount, and cost. That structure keeps UK invoice preparation connected to the work behind each line item.

A UK invoice app needs VAT fields when the supplier is VAT-registered and the supply is taxable. VAT invoices must show the supplier's VAT number, display VAT separately, and include the VAT rate used. Non-VAT-registered suppliers should not add VAT to invoices, although they still need the normal supplier, customer, date, description, amount, and total fields.
Yes. UK electronic VAT invoices are optional and do not require notifying HMRC. The electronic invoice must contain the same information as a paper invoice, and the sender must ensure authenticity of origin, integrity of data, legibility, and customer agreement. A PDF or electronic system still needs the correct invoice number, dates, supplier details, customer details, VAT details where applicable, and total owed.
The invoice should show the VAT rate that applies to the supply. The UK standard VAT rate is 20% for most goods and services, the reduced rate is 5% for qualifying supplies, and zero-rated supplies use 0% while still being accounted for where applicable. Exempt supplies are different from zero-rated supplies, so the invoice setup should not treat them as the same category.
A simplified VAT invoice can be used for supplies of £250 or less if the customer agrees and, for Northern Ireland businesses, the customer is not in an EU member state. It must show the supplier name, address and VAT number, tax point, description, VAT-inclusive total by VAT rate, and VAT rate. Higher-value invoices need the fuller VAT invoice details.
Missing identity, VAT, or payment-term details causes avoidable delays. Buyers often need the supplier's legal name, customer address, invoice number, supply date, invoice date, VAT number where applicable, tax point, and total owed before they can approve payment. Payment terms also matter because the UK default is 30 days without an agreed payment date.
Everhour lets admins set project billing status, mark specific tasks as non-billable, use custom task rates, and set member-rate exceptions. Reports can show billable time, non-billable time, billable amount, and cost, so invoice preparation starts from classified work instead of a manual review of every time entry.
Everhour Billing & Invoicing turns tracked billable time and expenses into client invoices, then marks invoiced time so it does not appear again on later invoices. Invoice data can be exported to QuickBooks Online, Xero, or FreshBooks, with status, number, issue date, and amount visible back in Everhour.
Classify billable work before invoicing, then carry approved time, rates, and non-billable exclusions into client billing. Everhour gives teams cleaner UK invoice preparation from tracked work.
