If you're a supplier to Staples, you've probably run into deductions—short-paid invoices that leave you wondering, “What went wrong?” But unlike Walmart or Target, Staples doesn’t use standard deduction codes to explain the reason for the deduction.
Instead, Staples uses something different—and a little confusing at first: invoice naming conventions. That means they bake deduction reasons right into the invoice number itself, using prefixes like VA, RT, or CL. No codes. No categories. Just a string of letters and numbers.
In this blog, we’ll break it all down in simple terms:
- What these prefixes mean
- How to read and understand Staples invoice naming conventions
- Where to dispute these deductions
- And finally, how you can save time and recover more money using automation.
Let’s decode Staples’ deduction process together.
Understanding Staples’ Invoice Naming Conventions
Staples’ method is simple in theory but can feel tricky in practice. Here’s how it works:
Whenever they deduct an amount from your invoice, they add a prefix like VA, RT, or CL to the invoice number. These letters tell you what the deduction is for.
Let’s look at a few quick examples:
- VA123456 – This is a Vendor Compliance deduction.
- RT789101 – That’s for a Return.
- GSM56789 – This one’s related to a Vendor Show Allowance.
There’s a full table Staples provides that maps all these prefixes to their deduction types and also gives the contact person or team for each case. We’ll share that below so you can bookmark or save it.
But before that, let’s break down a few more examples with pictures and context.

Staples Deduction Table
Staples has provided a detailed list of invoice naming conventions, the type of deduction they relate to, and the contact email you should reach out to. Here's a summary from that list:
But Keeping Track of All This Is Still a Headache…
Even if you have the table, staying on top of dozens—or hundreds—of deductions every month is a lot of work. You have to:
- Scan each invoice
- Decode the prefix
- Find the right contact or portal
- Gather proof documents
- Submit and follow up
That’s where automation can make a real difference.
