Vendor Master

What is a Vendor Master?

A Vendor Master is a centralised database that contains all the key information about a company's vendors and suppliers — including legal name, GSTIN, contact details, bank account information, ERP vendor code, and associated expense categories. It serves as the single source of truth for vendor data across the organisation's procurement, accounts payable, and ERP systems.

In expense and vendor payment management, the Vendor Master is the foundation on which all subsequent processes depend. Invoice OCR validates extracted vendor names against the Master. Approval routing uses vendor IDs to determine the correct workflow. Payments are made to the bank accounts stored in the Master. ERP entries are posted using the vendor codes defined there. Without an accurate, maintained Vendor Master, downstream processes break down.

A well-maintained Vendor Master also plays a critical compliance role in India, where GST input credit eligibility depends on the accuracy of vendor GSTIN details. Incorrect or outdated vendor information can result in disallowed input tax credits and compliance exposure. 

Examples of Vendor Master in Corporate Travel & Expense
1.
New Vendor Onboarding
Before any invoice can be submitted for a new vendor, the Finance Admin adds the vendor to the Master — entering their legal name, GSTIN, bank account number, IFSC, contact person, and ERP code. Once the vendor is in the Master, filers can select them when submitting invoices, and the system auto-populates the relevant details.
2.
Vendor ID–Based Approval Routing
A company configures approval rules based on Vendor IDs. Invoices from Vendor ID V-042 (a high-value IT supplier) are routed to the CTO and CFO for approval. This routing happens automatically whenever an invoice from V-042 is submitted, with no manual configuration required per invoice.
3.
ERP Code Mapping
Each vendor in the Master is assigned an ERP vendor code that corresponds to the vendor's account in SAP. When a vendor payment is processed, TripGain uses this code to post the correct ERP entry, ensuring the payment is accurately reflected in the vendor's payable account in the books.
Frequently Asked Questions About Vendor Master
1.
Who is responsible for maintaining the Vendor Master?
The Finance Admin or Finance Manager typically owns the Vendor Master. They are responsible for adding new vendors, updating bank details when they change, and deactivating vendors that are no longer active. Access to edit the Master should be restricted to authorised roles.
2.
What information is required to add a vendor to the Master?
At minimum, a vendor record in TripGain requires the vendor's legal name, GSTIN (for GST-registered vendors), bank account number, IFSC code, and an associated expense category. Additional fields such as contact person, ERP vendor code, and payment terms can also be configured.
3.
What happens if a vendor's bank details change?
The Finance Admin updates the vendor's bank details in the Vendor Master. All subsequent payments to that vendor will use the updated details. Payments already processed are not affected.
4.
Can one vendor be linked to multiple expense categories?
Yes. A single vendor can be associated with multiple expense categories in the Vendor Master, allowing invoices from that vendor to be filed under different categories depending on the nature of the expense.
5.
How does the Vendor Master help with GST compliance?
The Vendor Master stores each vendor's GSTIN, which is used to validate GST claims on invoices. Accurate GSTIN data ensures that input tax credit claimed on vendor invoices is eligible and defensible during a GST audit.
