Branded, VAT-aware invoicing for sole traders and small businesses. Sequential numbering, client and product memory, an invoice log and one-click PDF — VAT stays off until you cross the threshold, then switches on to produce fully HMRC-compliant VAT invoices, tax point and all.

Everything InvoiceIQ surfaces, in one place.

#

Sequential numbering, automatically

Every invoice gets a unique, ordered number with no manual tracking — clean records HMRC will be happy with.

%

VAT-aware by default

Under £90k? Invoices show no VAT. Register later and flip one switch in Settings — InvoiceIQ handles the rest.

Clients & products remembered

Save a client or a product once and quick-add it next time — no re-keying addresses or line items.

A searchable invoice log

Every invoice you've raised, with status — sent, paid, overdue — in one place you can actually find.

One-click branded PDF

Export a clean, on-brand PDF ready to send, formatted the way a small business should look.

Built for the whole *IQ family

Pre-loaded to invoice for EnergyIQ, FinanceIQ and QuizIQ work — or any product line you add.

Invoicing without the subscription bloat.

No per-seat SaaS, no features you'll never use — just fast, correct invoices and a tidy record, sized for a sole trader or a small team.

No VAT until you need it

Compliant for the under-£90k sole trader out of the box, with a clean upgrade path when you register.

Records that build themselves

Numbering, client memory and the invoice log mean your records stay in order without extra admin.

Send in seconds

Fill, save, export — a professional, branded invoice out the door in under a minute.

Fully HMRC-compliant VAT invoices, the moment you register.

Below £90k you raise clean commercial invoices; register for VAT and InvoiceIQ produces invoices carrying every field HMRC requires — automatically — with records kept audit-ready from day one.

VAT

Every mandatory field

Once registered: the "VAT invoice" title, your VAT number, per-line rate, net, VAT total and gross — all added automatically, nothing to remember.

Tax point shown

The time of supply is set on every VAT invoice, defaulting to the issue date — the field most templates quietly leave off.

Sequential numbering

Unique, unbroken invoice numbers with no gaps — the ordered audit trail HMRC expects to see.

REC

Record retention

Structured records you can keep and re-export for as long as HMRC requires you to retain them.

We structure your invoicing to current UK requirements but are not a tax or compliance authority; confirm your specific obligations with your accountant or HMRC. Full standards breakdown →
