How to set up MEV-WEB in InnoBooks

This guide walks you through setting up MEV-WEB (Revenu Québec’s sales recording system) in InnoBooks: opening the settings, validating your tax numbers, enrolling your digital certificate, managing user accounts and confirming that your transmissions work. Keep your tax identifiers handy.

MEV-WEB (Revenu Québec) configuration in InnoBooks — The MEV-WEB configuration: SEV identifiers, environment, NEQ and business sector (sample values).

What you’ll need

The POS add-on active on your company (the MEV-WEB module depends on it).
Permission to open the MEV-WEB settings (settings.mevweb.read).
Your SEV integration parameters: SEV Identifier and Authentication Key.
Your tax numbers: TVQ Number, TPS Number, NEQ and billing file number.
The MEV-WEB compliant mobile POS app installed on your device.

Steps

Open the MEV-WEB settings
Go to settings and open MEV-WEB (Revenu Québec). In the Configuration section, enter at least the SEV Identifier and the Authentication Key, choose the Environment (DEV, ESSAI or PROD), then fill in the Device Identifier, Certification Code and SEV Version as needed. Leave the Active checkbox ticked and click Save.
Validate your tax numbers
Click Verify my tax numbers with Revenu Québec. If everything checks out, InnoBooks shows Tax numbers are valid. Otherwise, fix your GST/QST numbers in your company settings and try again.
Enroll your digital certificate
Open the Digital Certificate card, then click Request Certificate. InnoBooks generates a new key pair and requests the certificate from Revenu Québec. Fill in the Operator Identification Number, the Sector and Authorization Code (format AAA-X9X9-X9X9), the TVQ Number (format 1234567890TQ0001), the Mandatory Billing File Number, the UTC Timezone and, optionally, a Nickname. Submit: the status changes to Valid.
Set up user accounts (if applicable)
In the MEV-WEB user accounts section, enter the Employee name and click Add account to register it with Revenu Québec, or Remove account to remove it. The operator’s tax numbers are used automatically — you only enter the name.
Confirm that transmissions work
Ring up a test sale from the MEV-WEB compliant mobile POS app, then return to the Transmission Dashboard. Check that the Confirmed counter increases and review the Last Transmission. If transactions remain Pending or Failed, use Retry pending. The SEV Journal details every compliance event.

Tips & edge cases

Risk-free testing: enable Training Mode to practice. Note: receipts produced show the TRAINING notice and must not be given to the customer.
Back office: the Back-office transmitter device field stays on Same device (no back office), unless your transactions are produced on one device and transmitted from another.
Offline: in the POS app, the MEV-WEB — Offline mode screen queues receipts and lets you Transmit now the batch once back online.
Certificate renewal: as expiry approaches, InnoBooks shows a warning. Use Replace Certificate at that point.
Data export: from the dashboard, export your transaction data as CSV or JSON for your records or your accountant.

Frequently asked questions

Where do I ring up sales once MEV-WEB is active?

In the MEV-WEB compliant mobile POS app. For a MEV-WEB company the web register is disabled: “Sales must be rung up on the MEV-WEB compliant POS app.”

A transmission failed — what should I do?

Open the dashboard and click “Retry pending”. Check the SEV Journal for the error code and message. A communication problem often clears itself once you’re back online.

How do I practice without sending real transactions?

Enable “Training Mode” in the MEV-WEB settings. Transactions are then transmitted as TRAINING and receipts show the TRAINING notice — they must not be given to the customer.
