Exchange rates displayed the way
accountants actually think.
Odoo shows 1 VND = 0.0000412 USD by default — confusing and error-prone.
This module lets you flip it to 1 USD = 24,300 VND
per journal, without touching Odoo's tax or payment flows.
This module is for you if…
- ✓ Your company currency is weaker than the foreign currencies you trade in (VND, LAK, IDR…)
- ✓ Accountants keep mis-reading 0.0000412 on invoices
- ✓ You need per-journal control — not a global switch
- ✓ You refuse to risk breaking a working accounting flow
Flip the number — not the workflow.
Odoo stores exchange rates as company currency → foreign currency. Technically correct, but counter-intuitive when your company currency is small: no market quote in the world reads "1 VND = X USD".
The module uses a computed + inverse intermediate field to display and accept input in the reversed direction, then writes back to the original field. Every tax computation, payment match, and ledger entry — 100% unchanged.
Before & After
Same USD invoice on a VND-based system.
1 VND = 0.0000412 USD
- Hard to read, easy to miscount zeros
- Doesn't match how markets quote rates
- Accountants waste time mentally inverting it
1 USD = 24,300 VND
- Reads the way the market quotes
- Whole-number input — no decimal mistakes
- Matches the accountant's mental model
Key features
Small in scope — sharp in execution.
Per-journal configuration
Adds a "Show Inverse Currency Rate" checkbox on account.journal. Each journal decides its own display direction.
Two-way — read and write
Users can edit the inverse rate directly on the invoice.
The system inverts it and updates the original
invoice_currency_rate field for you.
Absolutely safe with core
No field overrides, no monkey-patching. Every Odoo flow — tax, payment matching, refunds, audit trail — remains 100% intact.
Smart UI, auto show/hide
Flag off → native Odoo block displays. Flag on → native block hides, inverse block takes over. No conflicts, no duplicates.
Default off — backward compatible
Nothing changes after install until you opt in. Roll out journal by journal — zero migration risk.
Strict validation
Raises ValidationError if a user enters a rate ≤ 0,
mirroring Odoo's native constraint. No data integrity gaps.
How it works — 3 steps
From install to your first invoice in under 5 minutes.
Install the module
Go to Apps → search "Inverse Currency Rate" → Install.
Single dependency: account.
Enable per journal
Open a Sales/Purchase journal with a foreign Currency set and tick "Show Inverse Currency Rate".
Create an invoice
New invoices on that journal display the rate as 1 foreign = X company currency. Done.
Who it's for
Any business whose home currency is smaller than the foreign currencies it trades in.
VND-based companies invoicing or receiving USD, EUR, JPY, CNY…
LAK companies trading THB or USD — very large rates, even more in need of a readable direction.
Indonesia, South Korea, Cambodia… any currency that prints many digits per 1 USD.
