Odoo 20 accounting and reporting updates

After the keynote, Odoo Experience 2026 had sessions on Reporting, Bank synchronization and Hidden gems. Below, what matters for accounting and reports, with the Contaldia filter (Spain first) and screenshots from those sessions. It is still not “Odoo 20 in production in Spain”: it is what we saw in Brussels.

Bank: more connectors, duplicates and pay from the bill

In 20 there are more connected institutions (the session slide says 200+, in 50+ countries). In Spain we will still check bank by bank: we do not treat CaixaBank, Sabadell or BBVA as covered until we try it on a live database.

If the statement arrives short, Fetch Missing Transactions recovers lines. If duplicates slipped in, Find duplicate transactions flags them and you can delete them by hand.

Payments: Send to Bank uploads the SEPA remittance from Odoo. And from the bill itself, Register Payment in one click. The demo is KBC (Belgium). We will look at the Spanish circuit on 1 October; we do not treat it as identical.

Documents, VAT, assets and sequences

From Documents, many things can be done such as creating the invoice and editing the actions: send, create supplier invoice, move the PDF to another location in Odoo. Useful in any company to centralize documentation in Odoo.

In the purchase invoice, lines can be grouped by VAT type. 

An entry is split into several lines (Split) to create an asset per unit, without having to redo the invoice manually.

The purchases dashboard warns of irregular sequences. In supplier invoices, a gap is not illegal, but to resequence it requires developer mode and Resequence, already available in previous versions.

Change period or date in bulk: entries are selected and Actions → Change Period. Very useful for moving or changing the date en masse of incorrectly accounted invoices in closed quarters or periods, easy to search and resolve.

Reconcile every bank on one screen

Accounting → Reconcile combines the pending statements. Auto-reconcile exists; it needs to be properly configured or it mixes what shouldn't be. It is useful and available since several versions, although personally, I prefer to do it bank by bank and keep it up to date to avoid accumulating or having to do massive reconciliations that may have some errors.

Taxes of another country, compared P&L and mismatches

When creating a tax from another country, Odoo offers to install the entire package from that country. In an easy way, we avoid creating taxes manually and prevent mapping errors in reports, a very good solution.

The P&L compares by amount and by percentage (Horizontal Analysis). The gear on the right opens the report settings without leaving the screen, allowing you to configure your company's report.

If the Balance Sheet does not balance (assets ≠ liabilities), there is almost always a chart account not mapped in the report. Accounts Coverage Report marks them in red. Contaldia advice: fix the account number so it fits the PGC; do not twist the report.

Composite reports: Accounting → Settings → Accounting Reports → New, check Composite Report, add the ones you want and upload them to the menu, allowing you to group several reports with a simple click.

Spreadsheets, % search and mass edit

From a report, a pivot table is inserted into an Odoo spreadsheet. The dashboard remains a sheet within the ERP, not an orphan Excel. A functionality that existed before but is very useful.

Two tricks have not been mentioned in OX 2026 but I use them every day. 
The % in the search omits what is between two words: useful for contacts or products with long names. 

And the bulk change of accounts, analytics or different items, if you select several entries (or invoices) and change the account in the list, it applies to all. Bulk editing of accounts, analytics and more, without entering one by one.

Reports: more columns, faster

The Balance Sheet in 20 has more columns than fitted in 19: before/after, debit and credit, percentage of a column, and a Load more to add others. Less parallel Excel for the same cut.

Speed and memory: Odoo drops the dictionaries of 19 and moves to data objects. In the demo, a user report went from 2.5 s to 0.2 s. It affects audit, balances, ledgers and journals. Session figures, not a Contaldia database.

There are snapshots of a report: computed once and reopened without hitting the whole journal again. And line grouping (by journal, by tag, by whatever you ask) goes further than in 19.

How we will look at this

Contaldia has been running Odoo since 2009. On 1 October, at 16:00, the online updates course: which of this touches closing, the 303 and the bank in Spain, and what is worth waiting for before upgrading a production database.

On 29 October, from 12:00 to 14:00, the full Spanish accounting course on Odoo 20.

As of 24 Sep 2026 Odoo had not yet published the formal 20 release notes on odoo.com. What only appears in partner blogs we leave as rumour. The figure “49 AI features” does not appear in these sessions: we do not use it.
