Question 1

What is Solas?

Accepted Answer

Solas is a mobile accounting app built specifically for UK freelancers and sole traders. It handles receipt scanning, bank syncing, double-entry bookkeeping, invoicing, quotes, VAT returns, Self Assessment, and quarterly ITSA submissions — all from your iPhone.

Question 2

Is Solas free?

Accepted Answer

Yes — the free plan includes full bookkeeping, invoicing, quotes, VAT returns, HMRC submission, receipt scanning, bank sync, and more. There's no trial and no expiry. Premium (£18/month or £199/year) unlocks higher deductions like multiple vehicles, actual cost methods, and fee-free invoicing.

Question 3

Is there an Android version?

Accepted Answer

Not yet. Solas is currently available on iPhone only.

Question 4

Is Solas secure?

Accepted Answer

Yes, Solas uses bank-level 256-bit encryption to protect your data. Bank connections use FCA-regulated Open Banking providers — we never see your login credentials. We are fully GDPR compliant.

Question 5

Can Solas submit my tax return to HMRC?

Accepted Answer

Yes. Solas submits VAT returns directly to HMRC through the Making Tax Digital API. For income tax, Solas submits quarterly ITSA updates and generates your SA103 form data.

Question 6

Do I still need an accountant?

Accepted Answer

Solas handles day-to-day bookkeeping and tax compliance. For most sole traders, that covers everything. For complex situations, we recommend consulting a qualified accountant.

Question 7

What banks can I connect?

Accepted Answer

Solas connects to 60+ UK banks via Open Banking, including Barclays, HSBC, Lloyds, NatWest, Santander, Monzo, Revolut, Starling, Chase, Nationwide, and more.

Question 8

What happens if I cancel Premium?

Accepted Answer

You keep full access to the free plan — your data, bookkeeping, invoicing, quotes, and HMRC submissions all continue to work. You simply lose access to Premium features.
