Why Kabeer Developed the Nigeria Tax Addon for SAP B1

Navigating Nigeria’s complex tax structure—like Withholding Tax (WHT), VAT, NCD, and Cabotage—can be time-consuming, error-prone, and frustrating for finance teams. Kabeer Consulting Group developed this add-on to eliminate manual tax reversals and bring automation, accuracy, and compliance to your SAP B1 system.

Here’s what inspired us:

Too much manual work:
- Finance teams were spending hours manually calculating and reversing tax entries.
High risk of posting errors:
- Manual tax reversals often led to mistakes, duplicate entries, or incorrect GL postings.
Need for Nigeria-specific tax automation:
- Generic ERP systems don’t cater to Nigeria’s unique tax reversal requirements.
Faster audits & clean records:
- Businesses needed clear, automated JE records for better compliance and audit readiness.
Real-time insights & control:
- Companies wanted an easier way to track tax statuses, reversal history, and failed postings.

Functions of Nigeria Tax Addon for SAP B1

Configuration

Tax Reversal Configuration

This screen is used to define the setup. A dedicated table named Tax Reversal Setup will be created in SAP B1.

Users can define and configure WHT Tax and other tax combinations.
Tax breakup will be mapped based on Tax Codes created under WHT Tax Setup.

Tax Configuration

The Add-on will automatically post a Reversal Journal Entry (JE) for all AR and AP Invoices.
If an AR Invoice, AP Invoice, AR Credit Note, or AP Debit Memo is cancelled, those documents will be excluded from the reversal process.
If any of the above documents already have a reversed tax amount, they will also be excluded from future reversal entries.
A UDF (User-Defined Field) will be available on each document:
- Reversal Posted – Default value is “No”, changes to “Yes” once the reversal JE is posted.
- JE No. – Displays the Journal Entry number once posted.
AR Credit Memo and AP Debit Memo are included in the auto-reversal process.
- If any document fails during JE posting, an error message log will record:
- Successfully posted invoice numbers
Failed invoice numbers
A detailed report for failed postings will also be available.

Step-by-Step Process

Step 1:

The original transaction is posted using an AR Invoice, AP Invoice, AP Credit Memo, or AR Credit Memo.

Step 2:

The tax amount is automatically reversed (based on the mapping from the Tax Reversal Setup).

Step 3:

The Add-on matches the WHT Code with the configuration in the Tax Reversal Setup screen to determine the correct posting.

Step 4:

A reversal Journal Entry (JE) is posted automatically.

Transactions

Key Decision Document – Warehouse

In this screen, the AP Invoice is entered and the corresponding reversal Journal Entry (JE) is automatically posted.

Journal Entry

This is the standard JE created upon posting an AP Invoice.

The withholding tax amount is credited, and
The tax value is posted to a common account (Withholding Tax Account), which is mapped in the system through the setup.

Reversal Journal Entry

This is the automatically generated Tax Reversal JE for the AP Invoice.

The system debits the Withholding Tax Account, and
Credits other GL accounts based on the predefined Tax Reversal Setup configuration.

Tax Reversal Manual Posting

If, for any reason, the reversal JE is not posted automatically, the Manual Reversal Posting screen allows users to handle these documents manually.

Tax Reversal Manual Posting

This screen displays only those documents that have not yet been reversed.
Users can:
- Select the document
- Choose the document type
- Enter a date range (From Date – To Date)
- Input the document number
After entering these details, clicking the “Post JE” button will automatically post the reversal JE into the system.
