Your company has moved to a new office, opened an additional branch, or relocated its operations to another Michigan city.
You want the State of Michigan to have the correct information, so you open SIGMA VSS and look for an address update option.
That seems straightforward.
However, SIGMA Vendor Self-Service supports multiple addresses, business locations, and contact assignments. Changing one address doesn’t necessarily update every record associated with your company.
SIGMA VSS Has More Than One Address Function
Michigan’s official SIGMA VSS resources identify several separate account-maintenance operations.
These include updating an existing address, editing contact information associated with an address, and adding another business location.
Those functions serve different purposes.
If your company has permanently relocated, updating an existing address may be appropriate.
If your company has opened another branch while keeping its original office, adding a business location may be the better option.
Don’t treat these as interchangeable actions.
Understand Address Types
SIGMA VSS documentation describes different address assignments within a vendor account.
For example, the system’s address-management materials identify ordering, billing, and account-administrator address types.
A company might use one office for general correspondence and another for handling purchase orders.
These distinctions matter because an address can have a specific operational purpose.
Updating your headquarters address doesn’t necessarily mean that every other address assignment should change.
Moving an Office Is Different From Opening a Branch
Consider two situations.
Situation A: Permanent relocation
A consulting firm closes its Lansing office and moves its entire operation to Grand Rapids.
The company needs to review its existing address information and determine which records should reflect the new location.
Situation B: Additional branch
A maintenance contractor keeps its Lansing headquarters but opens a second office in Flint.
Replacing the headquarters address with the Flint address would misrepresent the company’s structure.
Michigan specifically provides an Add a Business Location function for organizations that need additional locations.
Choose the process that matches what actually happened.
Contact Information May Need Separate Attention
An office move often involves more than a new street address.
Your company may also change its telephone number, primary representative, or departmental contact information.
SIGMA VSS provides an Edit Contact Information function associated with addresses on the account.
Michigan’s guidance identifies contact names, phone numbers, and email addresses as information that can be maintained.
If your company relocates and assigns a different person to handle state procurement communications, review both the address and the contact details.
Check Which Contact Is Associated With Each Address
A business may have different representatives for purchasing correspondence, contract administration, and other responsibilities.
Updating the primary contact doesn’t necessarily mean that every address-associated contact has been reviewed.
For example, a company might relocate its administrative office while leaving a regional purchasing coordinator at the original branch.
Before replacing contact information, identify which person should remain responsible for each function.
The goal is to maintain accurate assignments, not simply make every contact record identical.
SIGMA VSS Provides an Address Update Guide
The State of Michigan maintains an in-application guide called Update Address.
Its purpose is to help vendors change an address associated with their account.
The guidance is available through the Advantage Assistant feature within SIGMA VSS.
Michigan also provides separate instructions for editing contact information and adding a business location.
This is useful because the correct workflow depends on the kind of change you’re making.
Verify the Address Carefully
Michigan’s vendor registration materials describe address validation against postal standards.
An entered address may be compared with a standardized version.
If the system presents an address correction, review it rather than automatically assuming the original entry is preferable.
Pay attention to suite numbers, street abbreviations, city names, and ZIP codes.
A technically valid address isn’t necessarily the correct address for your particular office.
A New Location Doesn’t Automatically Update Your Business Types
SIGMA VSS also maintains Business Types used for supplier classification and certain state purchasing initiatives.
Some classifications involve business location.
For example, Michigan identifies location-related categories such as Michigan Principal Location and Qualified Opportunity Zone by Principal Location.
If your company relocates, review whether the move affects any location-based classifications previously selected.
An address update shouldn’t be assumed to automatically establish eligibility for a purchasing program.
Review Your Business Profile After the Move
After making the necessary changes, review the relevant account information.
Check that the existing address reflects the correct location, any additional branches are represented appropriately, and the associated contacts remain accurate.
Also review whether the move affects information used in your procurement activities.
Michigan specifically advises vendors to keep their SIGMA VSS profiles updated whenever company information changes.
When to Contact SIGMA Support
If you’re unsure whether to replace an address or add a new location, describe the business change clearly.
For example:
Platform: SIGMA VSS
Business change: New branch opened
Existing office: Lansing, Michigan
Additional office: Flint, Michigan
Requirement: Retain the original office while adding the new location
Question: Should the new office be created through Add a Business Location, and do any address-contact assignments need updating?
This gives support a specific issue to investigate.
Don’t Replace Records That Should Remain Active
The biggest mistake is assuming that every business-location change requires overwriting the existing address.
Sometimes that’s correct.
Other times, the company needs to preserve the original location and create an additional record.
SIGMA VSS supports both scenarios through different maintenance functions.
When updating your company information in sigmavss, identify whether you’re changing an existing address, maintaining an associated contact, or adding a separate business location. Using the appropriate function helps keep your sigma vss profile consistent with your actual business operations.
