Odoo modules
built for operators.

Twelve years running a US distributor. The only way to get the right software was to build it. Laudon Labs ships the modules that generalize — sanitized, documented, and maintained.

bounced_payment_return

One-click workflow for bounced checks, NSF, and ACH returns.

$149 one-time · per database

Handling a bounced check in vanilla Odoo takes four to five steps and is easy to get wrong. This module collapses the workflow into a single wizard with a full audit trail.

  • ✓ Reverses the payment entry — keeps original bank deposit matching intact
  • ✓ Reopens the original invoice, restores amount due automatically
  • ✓ Optional bank-fee invoice, posted and ready to collect
  • ✓ Full chatter audit on payment, invoice, partner, and fee invoice
  • ✓ Outstanding-Receipts lines pre-positioned for next bank statement

// philosophy

Built the way operations software should be built.

01

Clean inherits only

No core overrides. No model replacements. Every module sits on top of Odoo, never under it — so upgrades never break.

02

Operator-first, not feature-list-first

Every module solves a specific, recurring operational problem. If it doesn't save someone real time in real life, it doesn't ship.

03

Full audit trail, by default

Every meaningful state change posts to chatter with context. Your accountant will thank you, and your reviewer will too.

04

Narrow scope, deep quality

Small surface area, well-tested, actually supported. No half-finished features or vaporware screenshots.
