Invoices Reference

Aims to simplify the “references” fields on the invoices.

We observed difficulties for the users to file the references (name, origin, free reference) and above all, to understand which field will be copied in the reference field of the move and move lines.

The approach here is to state simple rules with one concern: consistency. The reference of the move lines must be the number of the document at their very origin (number of a sales order, of an external document like a supplier invoice, …). The goal is for the accountant to be able to trace to the source document from a ledger). The description of a line should always be… well, a description. Not a number or a cryptic reference.

It particularly fits with other modules of the bank-statement-reconcile series as account_advanced_reconcile_transaction_ref.

Fields

Enumerating the information we need in an invoice, we find that the mandatory fields are:

• Invoice Number

• Description

• Internal Reference (“our reference”)

• External Reference (“customer or supplier reference”)

• Optionally, a technical transaction reference (credit card payment gateways, SEPA, …)

Now, on the move lines:

• Name

• Reference

• Optionally, a technical transaction reference (added by the module base_transaction_id)

Let’s see how the information will be organized with this module.

Customers Invoices / Refunds

Information	Invoice field	Instead of (in base modules)
Invoice number	Invoice number	Invoice number
Description	Name	–
Internal Ref	Origin	Origin
External Ref	Reference	Name

Information propagated to the move lines:

Move line field	Invoice field
Description	Name
Reference	Origin, or Invoice number if empty

Supplier Invoices / Refunds

Supplier invoices have an additional field supplier_invoice_number that we consider as redundant with the reference field. This field is kept and even set as mandatory, while the reference field is hidden.

Information	Invoice field	Instead of (in base modules)
Invoice number	Invoice number	Invoice number
Description	Name	–
Internal Ref	Origin	Origin
External Ref	Supplier number	Supplier number

The reference field is hidden when the reference type is “free reference”, because it is already filed in the Supplier invoice number.

Information propagated to the move lines:

Move line field	Invoice field
Description	Name
Reference	Supplier number, or Invoice number if empty
