eCommerce Questions




Question: How do we handle variable pricing in the pricebook?
ANSWER: Pricebooks should contain pricing on all items (repeatable work). In an instance an item or service needs to be priced differently we will work together to update the current pricebook rates in place. We can create price ranges for commodities which change frequently (fuel, etc.) in the pricebook. 

Question: How often can suppliers update pricing? Is there a standard?
ANSWER: The review frequency should be determined and mutually agreed in writing with your Hess Contract Manager. 

Question: How should suppliers manage third party charges that are reimbursable under contract?
ANSWER: Third party charges should be captured in the pricebook where possible. Work with your third party suppliers to determine rates upfront where possible. If the charges are unknown, the supplier will need to provide supporting documentation to verify charges.

Blanket Purchase Orders


Question: Why are Blanket Purchase Orders (BPOs) required?
ANSWER: SAP is our system for all business transactions including payments. A Blanket Purchase Order is a requirement of SAP and serves as a mechanism for processing invoices and receipting.

Question: How does Hess distribute BPOs to the supplier?
ANSWER: A Hess Contract Manager or Hess eCommerce team member will provide the supplier with necessary BPOs as well as the active BPO Reference Line.  One BPO will be issued for each Hess entity a supplier is performing work in; thus a supplier may have only one BPO or many.

Question: What is the planned duration for each Blanket Purchase Order (BPO)?
ANSWER: In theory, a Blanket Purchase Order is evergreen, which means it does not have an expiration date.  BPOs will be revised approximately every 2-3 years. We will not need to create a new one each year.

Question: Is there a dollar limit on the work order for planned versus actual for the BPO? 
ANSWER: Yes, there will be a limit; however, it will not stop the supplier from invoicing. This will be managed internally within Hess.

Question: Does the PO handle materials any differently? (Do we need to do anything different?)
ANSWER: The Material PO (Discrete PO only) allows for invoicing against one PO, multiple PO reference lines and multiple charge codes. Any excess material purchased on a PO will be returned to the Supplier and not to inventory.  
*  Note that any invoice submitted against a SERVICE Discrete PO referencing multiple PO Lines and/or multiple charge codes will be rejected.
*  BPOs should not be used for Warehouse inventory, only Discrete (Standard) POs.  

eCommerce and Open Invoice Software


Question: With all of the other Open Invoice customers, will we have the ability to upload into Open Invoice?
ANSWER: If you have the ability to extract a download from your accounting system, you can use third party tools to upload directly into Open Invoice. 

Question: Do we have an integration plan for those who are not in eCommerce?
ANSWER: We do.  Hess is continuing to enable targeted suppliers to use our eInvoicing solution.  This list of targeted suppliers changes as our business needs change.  If you are a non-eCommerce supplier and are interested in becoming one, please consult with your Hess Contract Manager.

Supplier Actions


Question: What will approved suppliers need before commencing work for Hess?
ANSWER: For standard eCommerce business, a Blanket Purchase Order (BPO), Work Order Number or Network/Activity Code, Contract Number, and Company Entity.  Note that this information is mandatory for successful invoice submission.

In special circumstances, a Standard (Discrete) PO may be issued.  In this event, a Cost Center or AFE may be assigned for use.  Any special circumstances will be communicated to supplier directly.

Question: Who do I contact if I have an Open Invoice related issue or question?
ANSWER: Communicate the invoicing changes to all of your employees. If you have problems once you begin the process, make sure to communicate to Hess by emailing your issue to eCommerceProject@hess.com . Below is an example format to email questions to the Supplier Self Service Team:

Subject line: Your company name – brief description of issue – date

Email Body: Explain issue in further detail; take a snapshot of Open Invoice screen if needed. Provide contact phone number in case further clarification is needed.

You will receive a Service Now Incident Number (beginning in INC) for each incident you email the eCommerce Support Team.  This same INC number will be used to communicate with you until the issue has been resolved.  When replying to the eCommerce Support Team, reply to the email address provided on your incident (hess@service-now.com).  Please do not change the email address in this field.  Also, please do not cc eCommerceProject@hess.com in your communications.  This will cause a duplicate incident number.




Question: What is a charge code?
ANSWER: A charge code is given to a supplier each time work is called out to be performed.  A charge code will come in the form of a Work Order, Network Activity code, Cost Center (for discrete Purchase Order only), or an AFE (for Materials only).

Question: Who do I contact if I do not have my charge code?
ANSWER: Your Hess Business Partner (field employee) will provide you with the proper charge code each time you are called out to perform work, but if you cannot locate your charge code data, please contact your Hess Business Partner (field employee) or Hess Contract Manager.

Question: How does a network/activity code or work order function in Open Invoice?
ANSWER: At minimum, one work order or one network will be created for the job.  Work orders will be created by well/lease for routine work. We may have 30 to 40 contractors who will all use the same work order or network number.  

Question: If I manually override the auto-populated Unit of Measure from the price book when invoicing, will that item be flagged as Off Contract?
ANSWER: YES.  Please do not manually override the Unit of Measure data when invoicing.  This will cause the item(s) to be flagged as Off Contract.

Question: How do I charge a discounted rate in Open Invoice?
ANSWER: If you are charging a discounted rate, build your discounts into your pricebook rate, or specific line item rate.  DO NOT USE the discount feature in Open Invoice.

Question: I need to have a submitted invoice disputed.  What do I do?
ANSWER: If you submit an invoice in error, contact our eCommerce team immediately so action may be taken.  If the invoice has not been approved, we will be able to have the Technical Reviewer dispute the invoice so you may correct it before resubmitting.
Question: When will the payment term start after a supplier submits an invoice in Open Invoice?

ANSWER: Payment terms start from the date the successful invoice is entered and submitted in Open Invoice. If you save the invoice but do not click “Submit”, the invoice will stay in draft mode. Please note that if your invoice has been rejected and re-submitted, the payment terms will begin upon date of successful submission in Open Invoice.

Question: How should suppliers manage charges that occurred over the weekend?
ANSWER: We encourage suppliers to submit daily when possible.  Refer to your Hess Commercial Agreement or Hess Purchase Order for details.

Question: If we have rental equipment with hours to be charged, how will we be able to do this on a daily basis? 
ANSWER: Supplier should work with their Contract Manager and the field supervisors on the location to determine the best method for your invoice frequency. The field supervisor should provide the vendor with the hours to be billed. If you are currently submitting rentals daily, weekly, or monthly; we want to optimize your submission time.   

Question: Will Work Order (WO) entry be restricted so suppliers can’t input more than one WO?
ANSWER: Yes, a Service invoice cannot be submitted with more than one purchase order and cost element (Network and Network Activity or Work Order).

Question: Where does the approval of the funds happen? (Is it in the WO itself?)
ANSWER: Yes, once the Work Order has been released (approved) then the work performed is also approved. Work Order cost reviews will monitor expenditures.

Question: How will professional service organizations be able to invoice on a daily basis?  
ANSWER: We encourage time to be entered daily into Open Invoice for real time costs; however, firms should invoice weekly at minimum. 

 If we invoice daily, Hess will be receiving a large volume of invoices to process versus batch processing on a weekly basis.  This places a larger burden on both the contractor and Hess?

ANSWER: We encourage suppliers to submit their invoices daily to get into an operating rhythm where possible.  Suppliers can also utilize software or tools to integrate with Open Invoice, known as Business-to-Business (B2B) transacting, which greatly reduces manual work.  We have had integration success with many integration solutions, including the following Open Invoice B2B integration solution providers:

Amalto Technologies


Atlas - ABS (Act Business Solutions)


NextGen Software




Question: How does Hess manage the approval process with reviewers who work on rotational schedules, shift work, etc.?
ANSWER: Hess continuously trains field employees with the expectation they will review their invoice items daily and set up substitution reviewers where appropriate. This is an area we are actively improving.

Question: How will I know if an invoice is rejected in Open Invoice?
ANSWER: Hess has developed canned rejection email replies for standard rejection notices. Free text is also available to further describe the rejection, which is viewable on the actual invoice journal. This should provide enough information to address the issue and enable the supplier to correct any necessary items and resubmit a successful invoice.  See below section titled "Why was my eInvoice rejected?" for more details.

Question: What is the time frame before a transaction will be escalated to the next person at Hess for approval?
ANSWER: The reviewers should approve their invoices within 24-48 hours.  If they have not approved in three days, they will receive a reminder; after five days the invoice will escalate to their supervisor and will continue escalating up within the Hess organization until it is approved or rejected.

Why was my eInvoice rejected?


Common automated eInvoice rejection responses and what they mean:

Rejection Response: Selected Price is not compliant with the Contract or Pricebook
Corrective Action:  Review invoice and search for any item(s) with a RED OC alert, correct the price to make it compliant with the pricebook, then resubmit the invoice.

Rejection Response: Please contact contract manager to update PO Line for ERS.
Corrective Action:  The PO you are attempting to use for your service invoice requires updating in order for the invoice to process properly.  Please contact your Hess Contract Manager and indicate your rejection notice so proper updates can be performed on the PO.

Rejection Response: 
PO number, PO line number, or Charge Code is invalid or missing
Corrective Action:  Confirm the Purchase Order number, Purchase Order line, and Charge Code data with your Hess Business Partner (field employee) or Hess Contract Manager to ensure accuracy, then resubmit the invoice.

Rejection Response: Invoice should only have debit lines
Corrective Action:  Each invoice should only contain debit or credit items, not both.  If submitting a CREDIT invoice, ensure you are choosing CREDIT instead of ORIGINAL invoice and the quantity of item(s) is negative, then resubmit the invoice.

Rejection Response: All invoices require backup documentation.  Please resubmit with appropriate justification
Corrective Action:  Attach mandated backup documentation, then resubmit the invoice.

Rejection Response: Company Code xxxx is not the same as the SAP CompanyCode
Corrective Action:  The Purchase Order you are attempting to submit against may not be valid for the Company Code you are submitting against.  Confirm that the two items are pointed to the correct Company Entity, or consult with your Hess Business Partner (field employee) or Hess Contract Manager to ensure accuracy, then resubmit the invoice.

Rejection Response: All line items must reference the same PO, PO Line, and Charge Code
Corrective Action:  One invoice can only reference one PO, PO Line, and Charge Code, and all data must point to the same Hess Company Entity (Service Invoices only - Material Invoices are configured differently).  Confirm the data with your Hess Business Partner (field employee) or Hess Contract Manager to ensure accuracy, then resubmit the invoice.

Rejection Response: The total amount of the ORIGINAL INVOICE must be greater than 0.
Corrective Action:  Resubmit the invoice using CREDIT INVOICE from the Invoice Type drop down menu.

Rejection Response: Invoice header should have contract reference
Corrective Action:  Every invoice must reference a contract number.  Confirm the contract number with your Hess Business Partner (field employee) or Hess Contract Manager to ensure accuracy, then resubmit the invoice.

Rejection Response: Invalid PO line.  Please consult your Business Partner for an updated PO/PO Line
Corrective Action:  Confirm the active Purchase Order line with your Hess Business Partner (field employee) or Hess Contract Manager to ensure accuracy, then resubmit the invoice.

Rejection Response: Cost Center not allowed on Blanket POs (47xxxxxxxx).  Contact your Hess representative for Network Activity or Work Order
Corrective Action:  Only a Network Activity or Work Order may be referenced when invoicing against a Blanket Purchase Order (a Cost Center may be referenced on a discrete Purchase Order only).  Please confirm the charge code data with your Hess Business Partner (field employee) or Hess Contract Manager to ensure accuracy, then resubmit the invoice.

Rejection Response: All Items must be on-contract.
Corrective Action:  If your account is designed for invoicing 100% from pricebook, you must submit all invoice line items against the pricebook, not your catalog.  Please review your invoice, specifically any line items with a yellow alert.  If the item(s) on your invoice are not in your pricebook, please reach out to your Hess Contract Manager to determine if a pricebook update is needed.
