Payments

We value our suppliers and know being paid in a timely manner is crucial to positive, long-lasting relationships.

Important Update: Payment Cycle change

As we work to streamline and standardize everyday ways of working, we’ve made an important change to our payment cycle.

The change is the result of a comprehensive review of our accounts payable processes in November 2024. Knowing our commitment to long-term success necessitates continuous innovation in our business practices, the shift allows us to better leverage industry best practices. First initiated May 2025, payments are now processed weekly rather than daily. Invoices due Saturday through Friday will be paid the following Wednesday. We acknowledge this cycle may vary based on local mandates as regulatory requirements vary across countries.

Know we remain committed to fostering growth and cultivating lasting supplier relationships. Please contact [email protected] with any questions or concerns.

Thank you for your continued partnership.

Paying Our Suppliers

Our suppliers play an important role in helping us meet the needs of millions of people and pets who rely on our products and services. We now have standardized payment terms to simplify our invoice payment process. There are steps that you, as a Mars supplier, can take to ensure that our purchasing process is effective, and payments can be made on time.
Purchase Order
In most of our markets, we operate a No PO-No Buy policy, which means that goods and services should not be provided without having a valid Mars Purchase Order. When invoicing for goods and services, suppliers must quote a valid Purchase Order number on the invoice in order to receive payment. If you have not received a Purchase Order, contact the person in Mars that has requested your services. Make sure you have a Purchase Order before you provide goods or services to Mars.

To help the billing process run smoothly, please check that the Purchase Order details are correct. If anything is not correct on your Purchase Order, contact the person in Mars that has requested your services.

After the goods or services have been provided, you can submit your invoice. Please check that all the details on your invoice are an exact match to what’s on your Purchase Order and what you have shipped or provided including:
  • Purchase Order Number
  • Mars entity
  • Line Items
  • Quantities
  • Unit of Measure
  • Price


To summarise:
Please do not provide goods and services before you have a Purchase Order
Check the PO details are correct
Make sure you reference your Purchase Order number on your invoice
Ensure that the details on the invoice match your Purchase Order
Invoices
Our preferred invoicing method is e-invoicing. Full details of the country specific invoicing requirements can be found at How to invoice | Mars Supplier Gateway.
Payment Terms
Our Standard Payment Terms policy is to initiate payment of all undisputed fees within 120 days of receipt of an invoice setting forth such fees. For small businesses, we offer 30-day payment terms and for medium-sized businesses, we offer 60-day payment terms.

For more information, please see Enterprise Size Registration for Mars Suppliers. Where applicable law requires different payment terms, this will be based on the supplier’s country of origin.

Payments will be made in accordance with the Mars standard third-party payment cycle procedure.
