Manager.IO and and Fiscal Harmony Integration Guide
Overview
This guide outlines the steps necessary to set up fiscalization using Manager IO and integrate it with Fiscal Harmony APIs. The process involves obtaining API credentials, configuring fields in Manager IO, and setting up the integration to enable fiscalization of invoices.
Prerequisites
Before proceeding with the setup, ensure the following prerequisites are met:
- Manager IO Account: You must have an active Manager IO account.
- Fiscal Harmony Account: You must have access to the Fiscal Harmony app (https://app.fiscalharmony.co.zw/).
- Access Tokens: Obtain the necessary API tokens from both Manager IO and Fiscal Harmony.
Step-by-Step Setup Guide
Step 1: Obtain Manager IO API Token
- Log in to your Manager IO account.
- Navigate to the API Settings section.
- Follow the instructions outlined in the Access Tokens Guide to generate your Manager API token.
- Save the API token securely. It will be required during the integration setup.
Step 2: Create Custom Fields in Manager IO
To comply with fiscalisation requirements, you need to add specific custom fields to your Manager IO system. These fields include:
- VAT Number: For storing the VAT registration number of the business or customer.
- TIN Number: For storing the Tax Identification Number (TIN) of the business or customer.
- Reason: To specify the reason for the transaction (e.g., sale, refund, etc.).
- HS Code: For storing the Harmonised System (HS) code of the product or service.
Instructions:
- Log in to your Manager IO account.
- Go to Settings > Custom Fields.

Add the following fields under the relevant sections (e.g., Customers, Products, or Invoices):
Field Name : VAT Number
Type: Text
Placement: Customer
Field Name : TIN Number
Type: Text
Placement: Customer
Field Name : Reason
Type: Dropdown (e.g., Sale, Refund, Credit Note)
Placement: Credit Note
Field Name : HS Code
Type: Text
Placement: Inventory item and Non-inventory item
Step 3: Obtain Fiscal Harmony API Credentials
- Visit the Fiscal Harmony app at https://app.fiscalharmony.co.zw/login and log in to your account.
- Navigate to Settings > API Keys Page.
- Create an API key for your account and give it a name (e.g. Manager IO). Enter your 2FA and then save.
- Here the API key and API secret will be shown. Save the API key and secret securely in a safe place, as the API secret will only be shown once. It will be required during the integration setup.
Step 4: Set Up Integration on the Provider's End
Once you have the following information ready:
- Manager IO API Token
- Fiscal Harmony API Key and API Secret.
- Custom fields configured in Manager IO
Provide this information to the integration provider (or technical team). They will:
- Configure the backend to connect Manager IO with Fiscal Harmony.
- Map the custom fields (VAT Number, TIN Number, Reason, HS Code) to the corresponding fields in Fiscal Harmony.
- Test the integration to ensure seamless communication between the two systems.
Step 5: Receive the Relay Link
After the integration is complete, Fiscal Harmony will provide you with a Relay Link . This link enables you to fiscalise your invoices directly from Manager IO.
How It Works:
- When you create an invoice in Manager IO, the system will automatically send the invoice data (including VAT Number, TIN Number, Reason, and HS Code) to Fiscal Harmony via the Relay Link.
- Fiscal Harmony will validate the data and return a fiscalised invoice with a unique fiscal code.
- The fiscalized invoice will be updated in Manager IO for record-keeping.
Step 6: Adding the Relay Link
- Go to Sales Invoice - this will display all your invoices
- Click Form Defaults - this displays all forms to make default in Manager IO.
- Tick Relay and paste your Relay Link.

- Click "Update" to save changes.
This activates the Relay Button, which is used for fiscalising invoices.
