In the words of our founders
What follows are not client testimonials: they are hypothetical examples of situations we commonly handle, using the real terms of the offer.
Coming from Stripe Atlas
Hypothetical example
A founder forms their LLC with Atlas and finds that annual compliance is on them. With Aiden, management, the dashboard and the Spanish-speaking advisor are part of the subscription; official fees are paid separately.
Operating fast in the UK
Hypothetical example
Companies House incorporation and Wise Business account managed end to end: the whole process is completed online, with no travel.
100%
process completed online
Documents up to date with Books
Hypothetical example
Invoices and documents are uploaded and organised in Aiden Books through the year, and at year end everything is easy to find to prepare the accounts.
Migrating an existing LLC
Hypothetical example
An LLC formed with another provider moves to Aiden: paperwork is brought up to date and state maintenance resumes from the dashboard.
Validating without a Spanish SL
Hypothetical example
To validate a project without the fixed costs of starting a Spanish SL with an accountant, a UK Limited with Aiden runs from €19.99/month plus official fees.
Questions for the advisor
Hypothetical example
Legal and tax questions are handled by the advisor over WhatsApp; on the PRO plan, with a response SLA under 2 business hours.
<2h

Getting paid with Aiden Pay
Hypothetical example
Client payments run on Stripe from the dashboard: Aiden adds no fee of its own — you only pay the payment provider's fee.

Incorporating from Latin America
Hypothetical example
From Argentina or Mexico, incorporation in the UK or Delaware is 100% remote, with no travel or physical presence, guided from the dashboard.

About plans
Reino Unido.
What's the difference between Standard and PRO UK?
Standard covers the essentials to operate: LTD incorporation, a registered London address while the plan is active, Aiden Books to upload and organise your invoices and documents, banking guidance and support in Spanish. PRO adds compliance filed by us: annual accounts prepared and filed, Confirmation Statement filed (the official Companies House fee —currently £50 for digital filing— is always paid by the client) and CT600, plus multi-user access with permissions (Teams), active tax optimisation, legal advice for your contracts, quarterly calls and priority WhatsApp support. VAT returns are quoted separately on both plans.
Is Teams included in PRO, or is it extra?
Teams is included in PRO at no extra cost. Invite as many members as you need (co-founders, accountant, assistant, advisors) with custom permissions. Only the admin pays for the PRO subscription. If you're on the Standard plan, this feature isn't available — you'd need to upgrade to PRO to use it.
What exactly does the $21.99/month fee cover?
The Standard plan covers the registered address, Aiden Books (organises your invoices and documents), support and account maintenance — with no lock-in. Filings (annual accounts, Confirmation Statement, CT600) are on the PRO plan or by quote. Official fees: the €190 setup fee includes the official Companies House digital incorporation fee, currently £100; the Confirmation Statement fee —currently £50/year for digital filing, subject to change by Companies House— is always paid by the client. Official fees may change.
How long does the full UK process take?
Timing depends on receiving complete documentation, processing by Companies House and, if you apply for an account, verification and approval by the financial provider. Company formation and account opening are separate processes; we keep you informed of each one and any outstanding documents.
Is there a minimum commitment?
No. You can cancel whenever you like. If you decide to close the company, we handle the strike-off with Companies House: the official fee —currently £13 for the digital application, subject to change by Companies House— is paid by you, plus our service.
Can I upgrade from Standard to PRO, or downgrade?
Yes, any time, with no notice period or penalty. The change applies from the next billing cycle.
What does the €190 setup fee cover?
A one-off payment, the same on Standard and PRO, covering the formation work (onboarding, collecting and reviewing documents, filing with Companies House) and including the official Companies House digital incorporation fee, currently £100. Official fees may change. There is no other formation cost.
What happens if I invoice a lot and go over the £90k VAT threshold?
Taxes warns you as you approach the threshold and we guide you on whether to register compulsorily or voluntarily. VAT registration and quarterly returns are not included in any plan fee: they are quoted separately based on your volume and circumstances, on both Standard and PRO.
Do you work with UK companies already formed outside Aiden?
Yes. If you already have a UK LTD and want to move its compliance and bookkeeping over to Aiden, we can take it on. The base price is the same; there may be a one-off onboarding fee to get things in order if your previous bookkeeping was messy.

We take care of everything.
