Your company is registered with the State of Michigan, and you’ve completed the basic vendor information.
You expect to receive notifications when state agencies publish opportunities related to your products or services.
But weeks pass without any relevant notices.
Does that mean Michigan isn’t purchasing anything in your industry?
Not necessarily.
One of the most important parts of SIGMA VSS is the selection of commodity codes. Without the appropriate codes, your vendor profile may not generate the notifications you’re expecting.
What SIGMA VSS Actually Does
SIGMA VSS stands for SIGMA Vendor Self-Service.
It’s the State of Michigan’s official platform for businesses, individual payees, and grantees.
For businesses interested in government contracts, the portal provides tools for reviewing procurement opportunities and responding to solicitations.
The state publishes its bid opportunities through this system.
You’ll also see the portal referenced as sigmavss in Michigan’s official website addresses and supporting materials.
But registering your business is only the beginning.
Your profile needs to describe what your company actually provides.
Commodity Codes Determine Which Opportunities Match Your Business
Michigan uses commodity codes to categorize goods and services.
These codes help the state identify suppliers interested in particular types of purchasing opportunities.
For example, a company supplying office equipment shouldn’t rely on the same commodity selections as a commercial landscaping contractor.
The codes associated with your profile influence which solicitation notifications you receive.
Michigan’s procurement guidance specifically emphasizes keeping these selections current.
Why Registration Alone Isn’t Enough
Completing your initial vendor registration doesn’t necessarily mean you’ve selected every relevant commodity category.
Your company may be fully registered while its profile contains incomplete or overly narrow selections.
That can limit the notifications reaching your business.
Before assuming that the notification system is malfunctioning, review the commodity codes associated with your vendor profile.
Choose Codes That Reflect Your Actual Services
Selecting commodity codes requires more thought than choosing the broadest category available.
Suppose your company provides commercial cleaning services.
You may need categories corresponding to janitorial services, building maintenance, or specialized cleaning, depending on the actual work offered.
Selecting unrelated categories merely to receive more notifications isn’t particularly useful.
It can fill your inbox with opportunities your company isn’t equipped to fulfill.
The objective is relevance, not the largest possible number of alerts.
Michigan Provides a Commodity Code Lookup
The State of Michigan maintains a Commodity Code Lookup resource to help vendors identify appropriate categories.
Use that reference when you’re unsure which codes match your products or services.
The state also provides a step-by-step guide for adding commodity codes to an existing SIGMA VSS profile.
This is useful when your company expands into additional services or discovers that its original selections were incomplete.
Your Email Information Matters Too
Commodity codes are only part of the notification setup.
Michigan explains that email addresses in the vendor profile are also necessary for receiving bid notifications.
If your business has changed its primary contact or no longer uses an old email address, review the contact information associated with the account.
Don’t assume updating your company’s website automatically changes the contact information maintained in sigma vss.
These are separate records.
Local Government Opportunities Can Be Relevant
SIGMA VSS isn’t limited to opportunities issued by Michigan’s central procurement office.
The state notes that schools and other local government organizations also use the system.
That makes commodity code accuracy useful beyond a single state agency.
A business serving schools, municipal departments, or public facilities may encounter opportunities from different participating organizations.
The categories you select help communicate the goods and services your company can provide.
Notifications Aren’t the Same as a Complete Opportunity Search
Email notifications are useful, but they shouldn’t be your only method of identifying opportunities.
SIGMA VSS also provides a public area for viewing published solicitations.
A business can review available opportunities rather than waiting exclusively for an email.
This is particularly helpful when you’ve recently changed your commodity codes or expanded into a new service category.
Don’t assume that every relevant opportunity will necessarily arrive as a notification.
Review Your Profile When Your Business Changes
Commodity codes shouldn’t be treated as information that never needs updating.
A company may begin by supplying one category of products and later expand into maintenance, installation, or consulting services.
If the business changes but its commodity selections remain the same, its profile may no longer accurately describe its capabilities.
Review your codes whenever your offerings change substantially.
Don’t Confuse Commodity Codes With Business Types
SIGMA VSS also allows vendors to identify business types.
These are different from commodity codes.
Commodity codes describe what your company sells or provides.
Business types describe characteristics of the business that may relate to specific state purchasing programs.
Updating one doesn’t necessarily update the other.
Make sure you’re editing the correct category of information.
What If Notifications Still Don’t Arrive?
Review the information already maintained in your vendor profile.
Confirm that the relevant commodity codes are present.
Check whether the associated email contact is current.
Then compare your selected categories with the kinds of solicitations actually published in the system.
If the information appears correct but expected notifications remain absent, contact the SIGMA Vendor Customer Support Center.
Describe the specific issue rather than simply reporting that the portal isn’t working.
A Useful Support Request
Platform: SIGMA VSS
Issue: Missing bid notifications
Business category: Commercial maintenance services
Commodity codes: Added to vendor profile
Contact email: Confirmed current
Question: Are the selected commodity codes and contact settings sufficient to receive matching solicitation notifications?
Providing these details helps support focus on the relevant configuration.
Registration Doesn’t Guarantee Relevant Notifications
Michigan’s procurement system gives vendors a central place to find state business opportunities.
But the usefulness of its notification features depends partly on the information supplied by each business.
An incomplete profile can leave a registered vendor unaware of relevant solicitations.
If your company uses SIGMA VSS but isn’t receiving expected bid notifications, review your commodity codes and contact information first. Accurate categories help the state identify what your business provides and connect your profile with appropriate purchasing opportunities.
