Running a business in Spain means two things at once: keeping clean books and meeting Spanish tax deadlines. As an Odoo partner, we run both from one system, in English, so you can see where your business stands without waiting for a quarterly summary. This page explains how it works for autónomos and SL companies, what your accountant looks after, and where to go next for the detail on each topic.
Talk to an English-speaking Odoo accountant about your business.
Why work with an English-speaking Odoo accountant
- Everything in one place: invoices, bank transactions, VAT and reports sit in a single Odoo database, so your accountant and you are always looking at the same numbers.
- Clear answers in your language: Spanish tax terms get explained the first time they come up, with the form number and the deadline attached.
- Real-time visibility: you can open your accounts on any day of the month and see income, expenses and VAT owed, rather than waiting for a quarterly email.
- An Odoo partner on your side: we know the platform and the Spanish rules together, so your set-up is shaped around the filings you actually have to make.
- Built for Spanish rules: VAT, quarterly returns and annual filings follow the Spanish calendar, and your accountant handles the filing as well as the bookkeeping.
Our complete guide to Odoo accounting in Spain covers the platform itself in more depth, including what it does well and who gets the most from it.
The number that matters most: 20
Spanish quarterly VAT and income tax returns are due by the 20th of April, July and October, and by 30 January for the final quarter. Most late-filing problems come from books that were not up to date when the deadline arrived. A system that categorises transactions as they happen, with an accountant reviewing each month, keeps you ahead of those dates. Our guide to Spanish tax deadlines in Odoo lists every filing and how the system reminds you.
What an Odoo accountant looks after
The day-to-day work falls into a few areas. Each one has its own page with the detail.
- Bookkeeping: bank feeds, categorisation and reconciliation happen automatically where possible, then get reviewed by a person. See bookkeeping automation in Odoo.
- Invoicing and payments: invoices go out from Odoo, payments match back to them, and reminders chase late payers. See invoicing and payment automation.
- Spanish VAT: IVA is calculated on every invoice and expense, then filed quarterly. See Spanish VAT accounting in Odoo, and our background guide to what IVA is in Spain.
- Tax filings and deadlines: quarterly returns, annual accounts and corporate or personal income tax are prepared from the same books.
- Financial reporting: profit and loss, balance sheet and cash position, ready when you or your bank ask for them. See financial reporting in Odoo.

Autónomos also pay social security contributions each month, which your accountant tracks alongside everything else.

How it works, step by step
1. Intro call: you tell us about your business, your current setup and what you want from your accounts.
2. Review of your current books: we look at what you have today, whether that is a spreadsheet, another platform or a previous accountant’s files.
3. Odoo set-up: we advise on how chart of accounts, tax settings, bank connections and invoice templates should be configured for Spanish requirements, and your in-house team or one of our network developers carries out the configuration.
4. Handover and migration: opening balances and history move across. If you are coming from another platform, see moving from Xero or Holded to Odoo.
5. Monthly rhythm: transactions are reconciled, your accountant reviews them, and you receive a short summary of where you stand.
6. Quarterly and annual filings: returns are prepared from your live books and sent to you for approval before filing.
Our page on working with an Odoo accountant in Spain describes what a normal month looks like and what we ask from you.

Dates move when they fall on a weekend or holiday, and individual circumstances change which forms apply to you. The full list, with how Odoo prompts each one, is on the tax deadlines page above, and personal filings are covered in our Spanish income tax return guide.
That is a lot of dates across a year, which is why the monthly review matters: each filing becomes a short check of books that are already accurate.
Implementation and development
We are an Odoo partner, and our focus is the accounting side: how Odoo should be set up so your books, VAT and reports come out right under Spanish rules. Most clients manage the technical work in-house, with their own team or administrator carrying out the configuration while we advise on what it needs to look like.
When a project needs a developer, such as a custom integration or a bespoke module, we can introduce one from our network and stay involved on the accounting requirements so the build matches how you file in Spain. Whichever route you take, your accountant reviews the finished set-up before your first filing runs through it.
What it costs
Pricing is quoted per business, based on your structure, transaction volume and the filings you need. Our guide to the cost of an Odoo accountant in Spain explains what drives the quote and what to ask any accountant before you sign.
Already have an accountant?
Many clients arrive with an accountant in place and a wish for better visibility or clearer communication. Changing mid-year is common and manageable. Our guide to changing your Odoo accountant in Spain covers how the handover works, what documents to request and how to avoid gaps around a filing date.
