Vendor accounts rules: five supplier problems and the first move

Each of the five supplier problems below has a first move that costs nothing. The move depends on what decides the problem: the agreement you signed, the supplier's own policy, the rules on credit decisions or the reporting rules. Get that right before you write to anyone outside the supplier.

What to take away

Only the agreement is specific to you, so read it first.
The terms themselves are contract law, which means the wording you signed beats anything you read on a page like this.
Supplier policy is unwritten and unpublished. You can ask about it, but you cannot look it up.
The consumer-credit rulebook is not the business-credit rulebook, and assuming otherwise is the most common error in this subject.

The five problems at a glance

Match the symptom first, then act. The first move in every row is a question or a re-read, not a complaint.

What happened	What decides it	First move
The due date was not what you thought	The signed agreement and the supplier's standard terms	Reread the terms you signed, then call accounts
Terms were reduced or withdrawn	The supplier's internal policy, bounded by the agreement	Ask what changed and what would restore them
You were declined and told nothing	The Equal Credit Opportunity Act and Regulation B	Ask for the reason in writing
Something wrong appeared on a file	The reporting framework held by the CFPB and the FTC, then the bureau's own process	Establish which bureau, then use its process
A charge appeared that was not discussed	The signed agreement	Reconcile the statement before disputing

Most trade account problems are row one or row two, and most people reach for row four first. When it genuinely is row four, the evidence-first process is set out in business credit disputes.

Which rulebook is your problem in?

Due date not what you thought?

Yes

The agreement: reread terms, call accounts

Terms reduced or withdrawn?

Problems one and five: a date or a charge you did not expect

Both are settled by the agreement. It governs the due date, the discount, the late consequences, the guarantee and the supplier's right to withdraw terms, together with the supplier's standard terms wherever they say the terms can change and how.

The four rulebooks

The agreement

Written down?: Yes, signed
Specific to you?: Only one
Governs: Due date, discount
Who holds it: You and supplier

Supplier policy

Written down?: No, unwritten
Specific to you?: No
Governs: Terms granted or pulled
Who holds it: Supplier

Regulatory rules

Written down?: Yes, published
Specific to you?: No
Governs: Offers, decisions
Who holds it: FTC, ECOA

Reporting rulebook

Written down?: Yes, published
Specific to you?: No
Governs: Reports, disputes
Who holds it: CFPB, FTC

Read the clause that matches the symptom, then call accounts with the clause in front of you. For an unexpected charge, reconcile the statement line by line before you dispute anything. Pay the undisputed part of a queried invoice on time, so the query never becomes a late payment.

Problem two: terms reduced or withdrawn

Terms can shrink without anyone breaking a rule. Inside the supplier, an unwritten policy decides why terms are granted, extended or pulled. It is not a rulebook you can read, but it explains decisions that look arbitrary from outside.

Four things get called a rule change. The supplier revised its standard terms and the revision took effect on renewal. Your account moved into a different internal category after a review. A bureau changed how it displays or matches something. Or a regulator actually published something new.

The first two are between you and the supplier, so ask what changed and what would restore the terms. Check the variation clause too: a common one lets the supplier amend the terms on 30 days' notice. The setup habits that keep an account in good standing are in credit foundations.

Problem three: a decline with no reason

A silent decline points to the rules on how credit is offered. They are published and mostly concern how offers are advertised and how decisions are communicated. The Federal Trade Commission's credit and finance guidance is the entry point.

The Equal Credit Opportunity Act is the statute most often relevant to a business applicant, and Regulation B is its implementing rule. Ask the supplier for the reason in writing. How the later steps run, if the answer is unsatisfactory, is covered in dispute escalation rules.

Problem four: a wrong entry on a file

Here the reporting rules apply: rules about credit reports, furnishers, accuracy and disputes. The published consumer framework, held by the Consumer Financial Protection Bureau and the FTC, is written around reports on people. Regulation V at 12 CFR 1022 is part of that framework.

The first move is practical. Find out which bureau holds the entry, then use that bureau's own process. What each bureau holds is in credit bureaus. Equifax, Experian and TransUnion publish furnisher notices when reporting duties shift, and those notices show whether anything changed on their side.

How far the consumer framework reaches a report about your business is a question for the CFPB, the FTC and a lawyer who works in business credit. The consumer side of that boundary is described in business credit scores rules.

When the first move does not work

Move outward from the document in your own hands, one step at a time, and keep each answer in writing.

Your own agreement. Nine times out of ten it settles the question.
The supplier's accounts function, in writing, so the answer exists later.
The bureau holding the record, if a file is involved.
The regulator, for questions about how the offer or the decision was handled.
A lawyer or accountant, for anything consequential.

Writing to the supplier before anyone else keeps the problem small, and the reply becomes evidence if the problem later reaches a file. Two habits help: read the guarantee before signing it, and keep one exact rendering of the business details everywhere.

Common questions

Did anything actually change in the rules?

No rule is involved until a regulator publishes one. If that happens, the change will appear in the regulator's own publication and in the bureaus' furnisher notices before it reaches a vendor's marketing email.

Is a business protected the way a consumer is?

Not identically, and the differences matter. Consumer rules are written for consumer reports and consumer credit. Where your situation turns on that, put one question to a lawyer: is this account a consumer credit transaction under ECOA and Regulation B, or a business credit transaction?

My supplier changed the terms mid-contract. Can they?

Read what you signed, because that is where the answer lives. Standard terms often reserve a right to vary on notice, and the length of that notice is the part worth checking now rather than later.
