Odoo Invoice Tax Stamp is an Odoo module that lets a seller add a tax stamp to customer invoices. This stamp is legal evidence that tax has been paid on the invoice, and it makes the document legally valid.
An admin sets up the charge once in the Invoicing section of General Settings. The setup asks for a label, a fixed amount, and the ledger account that will receive the value.
After this setup, any customer invoice in Odoo can carry the extra charge. It appears in the invoice totals under the configured label, and the final total includes it.
Sellers can click the Add Tax Stamp button on a draft invoice to apply the charge. They can also tick one checkbox so Odoo adds it automatically.
The fixed amount stays the same on every invoice, which gives accounting teams a predictable charge. The store listing covers Odoo releases from version 8 through version 12.
Additionally, if you want to print many customer invoices and vendor bills as one PDF file, then check Odoo Bulk Invoice PDF Generation.
Highlighted Features of Odoo Invoice Tax Stamp

Why Do We Need Odoo Invoice Tax Stamp?
Odoo Invoice Tax Stamp fills a gap in Odoo Invoicing, which offers no built-in option for a fixed stamp charge on customer invoices.
Without the module, accountants add this charge by hand as an extra invoice line. They must type the amount each time and remember which account it belongs to.
Manual entry leads to missed charges, wrong amounts, and values posted to the wrong account. Each of these mistakes means editing or cancelling the invoice later.
The module keeps the label, the fixed amount, and the account together in one settings block. A seller then applies the charge with one button, or lets Odoo add it on every customer invoice.
In practice, a label of GS with a Fixed Amount of 100.00 shows as a GS line of $100.00. Odoo places that line between the Tax line and the invoice Total.
Also, if you want to print invoices and sales orders straight from Odoo without downloading the PDF first, you can check Odoo Print Invoice Or Report Without Download.
Invoice Tax Stamp Use Cases for Odoo Sellers
-
Legally Valid Customer Invoices
Sellers whose invoices need proof of paid tax can add the required charge to every customer invoice from Odoo.
-
Flat Charge on All Invoices
Businesses that charge the same amount on each sale turn on automatic application and stop entering it by hand.
-
Charge Only Selected Invoices
Accountants who charge only some invoices keep automation off and click the Add Tax Stamp button on each draft.
-
Separate Ledger for the Charge
Finance teams that track this charge apart from sales choose a dedicated Tax Stamp Account in the settings.
Tax Stamp Configuration in Invoicing Settings
Tax Stamp Configuration sits in the Invoicing section of Odoo General Settings. Admins define the label, the fixed amount, and the ledger account in one place before any invoice uses them.
- Open Settings, go to General Settings, and select Invoicing.
- Enter the label in the Name field, for example GS.
- Set the Fixed Amount that Odoo adds to each stamped invoice.
- Choose the ledger in the Tax Stamp Account dropdown.
- Click Save to keep the new configuration.
Add Tax Stamp Manually to a Customer Invoice
The Add Tax Stamp button appears at the top of a draft customer invoice. A user clicks it to add the configured charge to that one invoice only.
- Create a customer invoice and add the invoice lines as usual.
- Click the Add Tax Stamp button beside Validate and Preview.
- Odoo adds the fixed amount under the configured label.
- The invoice total updates to include the added charge.
Add Tax Stamp Automatically on Customer Invoices
Automatically Add Tax Stamp is a checkbox next to the configuration block in Invoicing settings. When ticked, Odoo applies the charge to customer invoices without the manual button.
- Tick the Automatically Add Tax Stamp checkbox in Invoicing settings.
- The option help text reads Add Tax Stamp on customer invoice creation.
- Create the customer invoice and click Validate to confirm it.
- The validated invoice shows the labelled line with its fixed amount.
Tax Stamp Amount in the Invoice Total
The fixed charge shows on the invoice along with the product amounts. It sits as its own line in the totals block, so the customer can see what it adds.
- Untaxed Amount lists the sum of the product lines.
- Tax lists the tax computed on those product lines.
- The labelled line shows the configured name and Fixed Amount.
- Total adds the untaxed amount, the tax, and the fixed charge.
- Example: $947.40 plus $142.11 tax plus a $100.00 charge gives $1,189.51.
