Features

• Inherits account.report_invoice_document (priority 100) so the standard Invoice / Credit Note PDF is replaced everywhere it is used.
• Optional VAT column added next to each invoice line, showing price_total - price_subtotal per line.
• Optional Total column added next to each invoice line, showing the line total including taxes.
• Refund (storno) invoices can be printed with negative quantities, base, tax and total amounts so that the document visually matches the accounting sign.
• Section subtotals on grouped layouts are recomputed via get_section_subtotal, get_section_tax_amount and get_section_total_amount to remain consistent with the printed sign.
• New report_precision field on uom.uom lets each unit of measure define its own number of decimal places for printed quantities.
• The grouped lines view (td_quantity_grouped) is patched so the unit count column also respects the refund sign and UoM precision.
• All toggles are per company, stored on res.company, and exposed through the standard Accounting Settings form.

Configuration

All options are configured per company under Accounting -> Configuration -> Settings, in the Account invoice report options block (added right after the standard Account Reports block).

1. Enable the print options

1. Go to Accounting -> Configuration -> Settings.
2. Scroll to the Account invoice report options block.
3. Tick any of the following options, depending on what you need on the printed invoice:
   • Print Show Refunds — print refund / storno invoices with negative quantities, base, taxes and totals.
   • Print Invoice Tax Value — add a per-line VAT column.
   • Print Invoice Total Value — add a per-line Total column.
4. Save the settings. The options are stored on the current company; in a multi-company database, switch company and repeat the configuration if needed.

2. Set per-UoM print precision (optional)

The module also adds a Report Precision field on units of measure.

1. Go to Inventory -> Configuration -> Units of Measure -> Units of Measure.
2. Open a unit (e.g. kg, l, m) and set Report Precision to the number of decimal places you want printed on invoices for that UoM. Leave at 0 to fall back to the default behaviour.

No other setup is required — the inherited invoice template is used automatically by the standard Invoice print action on account.move.

To install this module, you need to:

• clone the repository https://github.com/NextERP-Romania/odoo-community
• add the path to this repository in your configuration (addons-path)
• update the module list
• search for "NextERP - Account Invoice Report" in your addons
• install the module

How it works

Once configured, the module is fully transparent — there is no extra report action or menu. Every invoice or refund printed from the standard Print -> Invoice action on account.move uses the inherited template.

Printing an invoice

1. Open a confirmed invoice from Accounting -> Customers -> Invoices (or Vendors -> Bills).
2. Click Print -> Invoice.
3. The generated PDF includes the extra VAT and/or Total columns if the corresponding company options are enabled.

Printing a refund (storno)

1. Open a posted Credit Note (out_refund) or vendor Refund (in_refund).
2. Click Print -> Invoice.
3. If Print Show Refunds is enabled on the company, all numeric values on the PDF — line quantities, base amounts, tax amounts, totals and section subtotals — are rendered with a minus sign.

How it works

• _compute_tax_totals on account.move inverts the sign of every base_amount, tax_amount and total_amount (and their currency counterparts) on refund moves whose company has Print Show Refunds enabled.
• Line, section and grouped-line helpers (get_section_subtotal, get_section_tax_amount, get_section_total_amount, _get_child_lines) apply the same sign so subtotals stay consistent with the per-line numbers.
• Each quantity span uses the UoM's report_precision when Print Invoice Tax Value is on, so a kilogram line with precision 3 prints as 1,250 instead of 1,25.
