Small business invoice software built for UK compliance
Invoicr is a free invoicing app built for UK sole traders and tradespeople that handles VAT, CIS compliance, and bank-to-bank payments without the card processor fees. As of June 2026, it's the only UK-focused mobile invoicing tool designed for self-employed workers who need HMRC-ready records without complexity.
What UK compliance actually means for your invoices
UK small business invoicing isn't just about getting paid. You need VAT compliance if you're registered, Construction Industry Scheme (CIS) deductions if you're in trades, and records that hold up to HMRC scrutiny. Most generic invoicing apps treat UK compliance as an afterthought. Invoicr was built from the ground up for it. The Free tier covers basic invoicing for sole traders under the VAT threshold. The Pro tier adds payment reminders and quotes. The Business tier includes 5 team seats, full VAT and CIS compliance tracking, and accountant export so your records go straight to your accountant in the format they need. This saves you hours of spreadsheet work come tax time.
How bank-to-bank payments cut your compliance headache
Invoicr's core payment method is bank-to-bank transfer via UK open banking, not card processing. On a £500 invoice, you pay around £4 in fees instead of £12.50 with a card processor. That's not just cheaper; it's cleaner for your records. Direct bank transfers leave a clear audit trail that accountants and HMRC prefer. Your clients see one payment method, payment fees are transparent, and you keep more of what you earn. The app works on iOS and Android, so you can send an invoice and see payment arrive within minutes, all from your phone.
Invoicing tiers that grow with your business
Free gets you started with 5 invoices per month and 3 customers, plus bank-to-bank payments. Pro (£9.99/month or £79.99/year) unlocks unlimited invoices, automated payment reminders, quotes, and WhatsApp invoice delivery so your clients get reminders on the channel they use daily. Business (£19.99/month or £179.99/year) adds 5 team seats, VAT and CIS compliance settings, and accountant export. For most UK tradespeople (plumbers, electricians, gardeners, tilers, decorators, cleaners, mobile mechanics), Pro is where the real value lands. You're not paying for features you'll never use; you're paying for the compliance and automation that actually save you time.
What compliance updates mean for freelancers in 2026
HMRC's focus on CIS audit trails and VAT digital records has tightened. Apps that don't automate compliance tracking leave you vulnerable to missed deductions or poor record-keeping. Invoicr's Business tier was built for this exact pressure. The app records CIS-relevant data, tracks VAT automatically if you're registered, and exports everything your accountant needs. You're not hunting through emails or spreadsheets; the app does the compliance legwork. Your client portal gives clients a secure URL to view invoices and payment status, reducing the back-and-forth emails that clutter your audit trail.
Mobile-first invoicing for tradespeople on the move
Most invoice software assumes you're sitting at a desk. Invoicr is native iOS and Android, built for tradespeople and consultants who work on site. You finish a job, snap a photo of the work, send an invoice from your van or truck, and your client's payment hits your account by end of day. The app runs offline too, so you're not dependent on signal. When you reconnect, everything syncs. For sole traders who bill by the hour or by the job, this mobile-first approach beats logging into a web portal on your laptop.
When to move beyond the Free tier
Stay on Free if you invoice fewer than 5 times a month and don't need payment reminders. Move to Pro if you're invoicing regularly, want to use WhatsApp to chase payments, or need quotes functionality. Jump to Business if you're hiring team members, managing multiple sites, or working with an accountant who needs export-ready records. Most UK self-employed professionals find Pro the sweet spot. The £79.99/year cost pays for itself the moment you avoid one late payment or recover one invoice faster than a text message would.

Frequently asked questions
Is Invoicr HMRC-approved for small business invoicing?
Invoicr is built to comply with HMRC standards for VAT and CIS. The Business tier includes VAT and CIS compliance tracking, and all invoices are HMRC-ready. Your accountant can import your records directly for tax filing.
Do I need to pay card processing fees if my client pays by bank transfer?
No. Invoicr's bank-to-bank payment method via UK open banking has a flat low fee (around £4 per £500 invoice) instead of a percentage cut like card processors. This is only offered in the UK and is one of Invoicr's key compliance advantages.
Can I use Invoicr if I'm not VAT-registered yet?
Yes. The Free and Pro tiers work for sole traders below the VAT threshold. The Business tier adds VAT compliance settings for when you register or manage VAT across team members.
Does Invoicr integrate with my accountant's software?
The Business tier includes accountant export, so you can send your records directly to your accountant in a format they can import. You're not asking them to re-enter data.
What happens if a client doesn't pay on time?
Pro and Business tiers include automated payment reminders you can send via WhatsApp or email. Invoicr doesn't chase debts legally; it gives you tools to remind clients faster than a phone call.
Is Invoicr available in the US or other countries?
No, Invoicr is built specifically for UK compliance (VAT, CIS, open banking). It's not available outside the UK.
