Connect Manager.io to Nigeria E-Invoicing
Manager.io Nigeria E-invoice Connector provides a business-scoped MBS/NRS integration with separate TEST and PRODUCTION processing, Sales Invoice and Credit Note support, NRS IRN and QR write-back, payment-status synchronisation and guided self-service onboarding.
Built around the Manager.io invoicing workflow
Process Nigeria e-invoices while continuing to use your normal Manager.io accounting workflow.
Sales Invoice Processing
Validate, sign and submit Manager.io Sales Invoices to the configured MBS/NRS environment.
Credit Notes
Process Credit Notes with verified linkage to the original submitted invoice and its NRS IRN.
TEST & PRODUCTION
Server-locked TEST and PRODUCTION routes keep sandbox processing separate from official production records.
NRS IRN & QR Code
Write the issued NRS IRN and encrypted QR image back into Manager.io for customer-facing documents.
Payment Status Sync
Synchronise final payment status after Manager.io confirms that the invoice closing balance has reached zero.
Business-Scoped Security
Each Manager.io business uses its own tenant record, encrypted credentials, subscription and processing history.
From installation to live processing
New businesses can complete the normal onboarding journey with minimal administrator intervention.

Prepare the business for a smooth setup
A few items should be ready before beginning the self-service onboarding process.
The business should already exist and be accessible in Manager.io.
Have the registered Seller TIN available for business registration.
TEST environment credentials are required to configure and test sandbox processing.
These are needed only when the business is ready to configure and activate live processing.
Business, customer and item/service information should be properly maintained.
Configure the base and any foreign currencies under Manager.io → Settings → Currencies.
Inventory and service items should have the appropriate classification codes.
Use country code NG and appropriate units such as EA for counted items or E48 for services where applicable.
Start with a trial. Upgrade when ready.

Common onboarding questions
Do TEST transactions affect official PRODUCTION records?
No. The application uses separate server-locked TEST and PRODUCTION routes with separate environment credentials and Manager.io operational fields.
How many free submissions are included?
A newly registered business receives 10 successful trial submissions. Failed validations or status checks do not count as successful submissions.
Can Production be configured during the trial?
Yes. A customer may configure, test and activate the separate Production profile while trial access is still available.
What appears on the customer invoice?
The standard customer-facing e-invoicing print profile is designed to expose the NRS IRN and NRS QR Code while keeping operational status fields hidden.
How does annual payment work?
Annual access is paid through the configured Selar checkout. After payment is verified, the tenant continues under the 365-day annual plan.
Can I start without Production credentials?
Yes. The business may begin with TEST configuration and trial processing first. The separate PRODUCTION profile can be configured when the business is ready to go live.
