Features

• Auto SGR child line on every draft invoice — adding a beverage line to a customer invoice or vendor bill instantly appends a paired account.move.line with the matching SGR product, current deposit rate and zero taxes.
• Parent/child sync — changing the parent line quantity, product or UoM updates the SGR child; removing the parent removes the child via ondelete='cascade'.
• No duplication on cross-module flows — when an invoice is created from an SO/PO/POS that already carries an SGR line, the module adopts the existing sibling through sgr_parent_line_id instead of inserting a second one.
• SGR Liability Account company setting — points at the RO 462 / 461 account used as default income and expense on every Is SGR Product. Exposed in Settings → Accounting → Fiscal Localization.
• Onchange on product — flagging a product as Is SGR Product pre-fills its income and expense accounts with the SGR liability account, keeping deposits off P&L.
• Per-invoice opt-out — every account.move carries an Auto-add SGR Lines boolean (after Source Document), defaulting from the company setting. Disable on documents that already carry SGR lines from EDI / e-factura.
• Tracks the SGR pair — is_sgr_line and sgr_parent_line_id fields on account.move.line make the deposit easy to filter, reconcile and report on.

Configuration

1. Pick the SGR liability account

Open Settings → Accounting → Fiscal Localization → SGR Liability Account and pick the third-party account that should hold the deposit. For Romania the standard choices are:

• 462 Creditori diverşi — when the company is a net debtor of the system (typical retailer that owes deposits to consumers).
• 461 Debitori diverşi — when the company is a net creditor of the system (retailer that has handed over more empties than what is held at the till).

The same account is reused on both the income and the expense side so that the deposit flows as a balance-sheet item, never through revenue or cost accounts.

2. Apply it on SGR products

In Inventory → Products, open each product flagged Is SGR Product. Toggling the flag triggers an onchange that pre-fills Income Account and Expense Account with the company SGR liability account. Override per product only if you need a sub-account split (per category, per warehouse, etc.).

3. Default behavior on new invoices

Each account.move inherits the company-wide Auto-add SGR Lines toggle from nexterp_sgr. The field appears on the invoice form right after the Source Document column.

• Keep it enabled for manual invoices you key in by hand — the SGR child line is added under each beverage line automatically.
• Disable it on individual documents when the SGR lines are already pre-filled by an external system (EDI, e-factura import, sync from another ERP). The orphan SGR sibling will be adopted by its parent line on save, so you still keep the parent/child link.

How it works

Manual customer invoice or vendor bill

1. Create the invoice in draft.
2. Add a beverage line with a product that has an sgr_product_id configured. On save, an SGR child line is appended immediately under it, with the matching SGR product, the deposit rate effective on the invoice date, no taxes, and the SGR liability account on both income and expense sides.
3. Change the parent quantity, product or UoM — the SGR child is recomputed. Remove the parent line — the SGR child is removed automatically via cascade.

Invoice generated from an SO, PO or POS order

When an invoice is created from a sale order, purchase order or POS order that already carries an SGR line (because the corresponding companion module added it on the source), the SGR sibling appears on the invoice with is_sgr_line=True but no parent. On save, the module recognizes it and writes sgr_parent_line_id on it — so the deposit is paired with its beverage line without ever being duplicated.

Posting

On post, the SGR amount books on the SGR liability account (462 / 461) on both the debit and the credit side, while the beverage line books on its standard revenue or expense account. The deposit therefore flows through the balance sheet, not through the income statement.

Opt-out per document

If the SGR lines are pre-filled by an external source (e-factura import, EDI feed, ERP-to-ERP sync), untick Auto-add SGR Lines on the invoice header — the module then leaves the upstream lines alone and only links orphan SGR siblings to their parents.
