Odoo Accounting: a complete guide to setting up your chart of accounts

Did you know that 75% of SMEs struggle to set up their chart of accounts in an ERP? At TSC Expert, specialist in Odoo accounting we have helped more than 200 organisations take this crucial step without stress. Odoo can seem intimidating at first: you find yourself facing a dashboard packed with modules, codes and options. Yet, once you understand the underlying logic, everything becomes smooth and intuitive. In this guide, you will discover how to structure your chart of accounts, automate your entries and steer your financial data like a true professional.

Understanding how accounting works in Odoo

The Odoo accounting module acts as the heart of your system: it centralises the management of all your operations, from entering invoices to producing reports. During installation, Odoo offers you a standard chart of accounts, modelled on the French General Chart of Accounts (PCG). You can adapt it, import a CSV file or create your accounts one by one. Each account is given a code, a label and a category (Asset, Expense, Income, Liability). This simple structure ultimately lets you generate a balance sheet and an income statement without resorting to tedious Excel spreadsheets.

Bank synchronisation: the key to fast reconciliation

You import your bank statements directly as CSV or via your bank's API; Odoo automatically matches each line to an account thanks to intelligent reconciliation. All you have to do is validate the matches in the interface: a phenomenal time saving and fewer risks of errors. (This is where automation reveals its full potential.)

“Odoo allowed me to cut the time spent on bank reconciliations by three,” confides a Sales Expert.

Setting up your chart of accounts step by step

The first step is to choose or customise your chart of accounts:

1. Selecting the standard chart
   In Configuration > Charts of Accounts, select the French PCG.
2. Importing a custom chart
   Upload your CSV file (structure: code, label, type) and let Odoo integrate your accounts within seconds.
3. Activating and deactivating
   Deactivate unnecessary accounts to streamline your menus and avoid any confusion during daily entry.

Once your chart is in place, you can enrich the accounts: edit the labels, adjust the codes or add analytic categories.

Creating and managing your customer and supplier accounts

For each customer or supplier, Odoo lets you link a dedicated account (for example “411000 – Customers” or “401000 – Suppliers”). In just a few clicks, you set up:

• The contact details and payment terms
• The invoicing flows to automate the sending of PDFs
• The default reconciliation rules (guaranteed time saving)

When you generate an invoice, Odoo automatically creates the associated journal entry: no more juggling between several screens. The consistency of your data is thus guaranteed.

Odoo accounting features

Odoo brings together all the building blocks essential to modern financial management: you freely create and customise your chart of accounts, you manage several journals (Sales, Purchases, Banks) in just a few clicks, and you track the evolution of your cash flow in real time thanks to dynamic dashboards. How does the integration of Odoo accounting work ? Thanks to a modular architecture, each transaction (invoice, payment, bank statement) automatically connects to the right account, which guarantees complete consistency of your entries.

With TSC Expert's support, automatic reconciliation matches your bank entries in one click (you save hours every month), analytic accounting segments your costs by project or profit centre, and the financial reports module generates balance sheets, income statements and general ledgers without any additional entry. You can also automate the extraction of invoice data via OCR (no more manual entry!), set up alerts when a threshold is exceeded and centralise all your VAT returns. (You see? Odoo is not limited to a mere entry editor: it is a genuine financial cockpit.)

Invoicing automation and tax management

Configuring taxes in Odoo is surprisingly simple: go to Configuration > Settings, enable VAT at 20%, 10% or 5.5%, and link them to your products and services. From then on, each sale applies the right rate and each purchase recovers the corresponding VAT. For the VAT return, a dedicated section lets you export an XML file compliant with the government standard. At TSC Expert, we recommend setting up a monthly reminder to generate and check your return before submission.

Leveraging financial reports and analytic accounting

Odoo offers several standard reports:

• Balance Sheet and Income Statement
• General Ledger and Aged Balance

These documents are generated in a few clicks and exported as PDF or Excel. To go further, enable the Analytic module: you create axes (projects, departments, cost centres) and assign each transaction to an axis. You thus obtain a detailed view of profitability, comparable to managing a kitchen brigade where each station (starters, mains, desserts) must balance its costs and sales.

“Analytic accounting is the compass that guides your strategy,” says a Sales Expert.

Towards an ever more automated accounting

The Odoo roadmap already includes OCR recognition of invoices (imported by a simple photo), real-time bank synchronisation and intelligent alerts to detect critical thresholds. Imagine a future where your chart of accounts self-adjusts according to your cash flows: this is the path along which Odoo will lead you, with the support of TSC Expert, Odoo integrator to configure and optimise each module, or benefit from responsive Odoo support when needed.
