Take card and ACH payments on your own Odoo checkout page.

Customers see one NMI option at your Odoo checkout and pay by card or from a US bank account. The card and bank fields are served by NMI, so your server only handles a one-time token. Approved card payments update the Odoo transaction and the invoice behind it.

One NMI option, two ways to pay

Your checkout list stays short. Buyers pick NMI once, then choose Card or Bank Account from a picker inside that option, and the matching fields appear. When the amount is not in US dollars, only the card fields are offered, because NMI settles ACH debits in dollars. Customers stay on your order or invoice page throughout.

Card details stay off your server

Your card compliance scope stays small. The number, expiry date and security code are typed into fields that NMI serves inside your own page, so they are tokenized in the browser. What reaches your Odoo server is a one-time token, which is worthless to anyone else. Shoppers never get bounced to a separate payment site to enter a card.

Pay large invoices by ACH debit

Large invoices can be paid from a bank account rather than a card. Choose Bank Account and three different fields appear: the name on the account, the routing number and the account number. NMI hosts them exactly as it hosts the card fields, and the money is taken as an ACH debit. Odoo offers this choice only when the payment amount is in US dollars.

Invoices reconciled without data entry

Your team stops reconciling NMI payments by hand. Once a payment goes through, Odoo matches it to the sale order or invoice behind it and marks that invoice paid. Nobody re-types amounts or compares the NMI portal against your ledger. A card payment is reconciled as soon as NMI approves it, while an ACH debit is only matched after it settles.

Refund a card in full or in part

You can return money to a card buyer from the Odoo transaction. Open the card payment, click Refund, and choose the full amount or a smaller one. NMI credits the customer, Odoo logs the refund against the payment it came from, and the credit note is handled for you. An ACH debit is the exception: refund it in the NMI portal, and only once it has settled.

Pending payments get chased for you

A shopper who closes the browser mid-payment will not leave your books stale. On a schedule, the app asks NMI about payments still pending from the past seven days and updates the matching Odoo transaction. You can also press Refresh from NMI on a single transaction to pull its status at that moment. ACH debits stay at Pending until NMI reports them settled.

How to connect NMI to Odoo

  1. Enter your two NMI keys

    Open the NMI provider record in Odoo's payment settings and fill in the Security Key and the Tokenization Key you copy from your NMI merchant portal. The app then addresses the correct NMI host for you.

  2. Try it in Test Mode first

    Leave the provider in Test Mode and run payments end to end with your NMI sandbox keys. When the results look right, move it to Enabled and swap in your live keys. No code changes are involved.

  3. Publish the payment method

    Mark the provider as Published so buyers can actually choose it. NMI then shows up on your storefront checkout, in the customer portal and on invoice pay pages, with Card and Bank Account held inside it.

  4. Watch payments settle themselves

    From here your customers pay the way they prefer, and Odoo updates the transaction and the invoice as NMI reports back. A background sync plus a per-transaction refresh keep slower bank payments accurate.

Questions before you buy

It runs on Odoo Enterprise, both on-premise and on Odoo.sh, and on Odoo Community on-premise. Odoo Online does not allow third-party apps, so the gateway cannot be installed there. We ship it for Odoo 17.0, 18.0, 19.0 and 20.0, and each of those versions is bought separately.

Yes, the gateway works with an NMI account you already hold. From your NMI merchant portal you copy two keys into Odoo: the Security Key, which is private, and the Tokenization Key, which is public. With those two values filled in, your provider is ready to accept payments.

Yes, for cards. Switch on manual capture and checkout only authorizes the card. You capture the amount when the goods go out, or void the authorization if the order falls apart. NMI has no authorization step for bank payments, so an ACH debit is always taken as a single charge and the app handles that case.

Yes. A customer can store a card in the NMI Customer Vault during checkout and then pay with one tap on a later order. The same stored card lets recurring invoices be charged without asking them again. Bank accounts are not stored, so an ACH payer types their account details each time.

ACH works on a delay. NMI accepts the debit straight away, but the funds only move at settlement some days later, and the debit can still be returned after that. Odoo holds the transaction at Pending so your accounts never show money that has not arrived. The background sync marks it paid once NMI reports settlement.

Card payments follow whatever your NMI account and its processor accept, since the app adds no currency rule of its own. Bank Account is an ACH debit and NMI settles those in US dollars only, so Odoo shows that choice at checkout for USD amounts and hides it for everything else.

Yes. Send a payment link with the invoice and the NMI option appears on the invoice pay page in the customer portal. A business client who would rather avoid card fees on a big amount can pay by ACH debit instead. Odoo reconciles the invoice once the payment is confirmed.
