Everything you invoice, spend, and owe — in sync
Stop stitching together a spreadsheet, a banking app, and a shoebox of receipts. Spiral HQ connects the whole money story, from "sent" to "settled" to "filed".
Send branded invoices in seconds and let automatic reminders do the awkward follow-ups. Watch each one move from draft to paid without lifting a finger.
Photograph a receipt and Spiral reads the amount, VAT and category for you — reclaim-ready.
Card, bank transfer, Direct Debit or Apple Pay — right from the invoice. Money lands faster.
Connect your account through Open Banking and Spiral matches payments to invoices automatically — so your books are always current, never a January scramble.
The only invoicing tool that keeps you right with HMRC
Most tools stop at "invoice sent". Spiral carries the number all the way through to your tax return — so tax stops being a deadline you dread.
Whatever you do, Spiral speaks your trade
"I used to spend the last week of every month building invoices and reminders by hand. Spiral does it while I sleep — I get paid faster and I barely think about it."
"I raise the invoice from the van before I’ve packed up the tools. Half my customers have paid by card before I’m home. Game changer for cashflow."
"We moved our whole practice over. Seeing every client’s VAT position and MTD status on one screen has saved us genuinely hundreds of hours a year."
"Income from six platforms, expenses everywhere, and I never knew my real take-home. Spiral untangled all of it and told me what to set aside for tax."
Plays nicely with the tools you already use
Bank feeds, accountants' software, payment providers and your storefront — connect once and Spiral keeps everything reconciled.

Everything you were about to ask
Is Spiral HQ recognised by HMRC?
Yes. Spiral is on HMRC’s list of recognised software for Making Tax Digital, so your VAT returns and Self Assessment submissions are fully compliant.
Do I need a card to start?
No. The Solo plan is free forever and the Professional trial runs 30 days with no card required. We’ll remind you before anything is charged.
What happens when I cross the VAT threshold?
Spiral watches your rolling turnover and warns you as you approach £90,000, then walks you through registering and switching on MTD VAT — no nasty surprises.
Can my accountant access my books?
Absolutely. Invite your accountant with the right permissions, or if they use Spiral’s Practice plan they can manage you alongside their other clients.
Will it work for my trade?
Spiral is built for the full spread of UK small business — freelancers, tradespeople, creators, landlords and SMEs. The dashboard adapts to how you work.
How secure is my financial data?
Bank-level 256-bit encryption, UK data residency, and read-only Open Banking connections. We never store your banking credentials.
Can I edit an invoice after it is sent?
Sent invoices are locked for compliance. Spiral guides you through cancel and regenerate flows with audit trails.
What is your refund policy?
Monthly plans are non-refundable. Annual plans can be refunded for remaining unused months if you cancel early.
Does Spiral support multiple tax regimes?
Yes. Configure VAT, GST, and local tax rules with validations to keep invoices compliant.
How do reminders and follow-ups work?
Define reminder sequences by segment and payment terms. Spiral tracks delivery and responses automatically.
Is there a customer portal?
Yes. Customers can view invoice status, download PDFs, and pay directly from a branded portal.
