What the promotion includes
It is a Holded promotion, not an isaak.pro one, for businesses in Spain. According to what Holded has told its partners:
- −70 % off the Holded licence for companies signing up to Holded for the first time (new customers, alta en Holded).
- −50 % off the Asesoría Pro plan for accounting firms.
- The discount applies for 3 months.
- Prices exclude VAT (IVA no incluido).
- For sign-ups from 9 to 30 November 2026.
The final terms of the promotion are the ones Holded publishes. Check them on Holded’s website before signing up.
Who it suits
- Business owners and freelancers in Spain who still manage their business with spreadsheets or with software they are not happy with.
- Groups with several companies that want them all in the same software.
- Foreign business owners in Spain looking for management software and support in their language: see Holded for foreign freelancers and companies.
- Accounting firms that want to move their clients to Holded and work with them in the same tool.
If you already use Holded, the −70 % does not apply to you: it is for new sign-ups. What you can do is connect your companies to ChatGPT and Claude with isaak.pro.
How to sign up, step by step
- Leave your details on the campaign page (in English, in Spanish or in Russian) or message us on WhatsApp.
- We contact you to understand your case and help you choose the licence you need.
- We help you sign up to Holded with the promotion and with the initial setup: tax details, invoice series, bank accounts.
- Whenever you want, connect your company to ChatGPT or Claude with isaak.pro: the first company is free.
What to prepare before signing up
To make the sign-up quick and the setup right from day one, have these at hand:
- Your company’s tax details: name or registered name, NIF or NIE and address.
- Your last issued invoice, to continue the numbering correctly.
- Access to your online banking, to connect your accounts.
- The list of your regular customers and suppliers (a spreadsheet will do).
If you work with an accountant, let them know: if they already use Holded, you can share the same information from the start.
And then: Holded with ChatGPT and Claude
Having Holded is the first step; using it every day is what makes the difference. With isaak.pro you ask your Holded in plain language (and in your language) how much you have sold, who owes you money or how much is in the bank. We explain it in Run your business with Holded and ChatGPT or Claude and in Holded in your language.
Frequently asked questions
What happens when the 3 months are over?
The licence goes back to Holded’s usual price according to its price list. Check Holded’s terms before signing up.
Does isaak.pro have a Black Friday discount?
It does not need one: the first company you connect in isaak.pro is free, forever. From the second one, the price is per company and month, separate from the Holded licence.
