10 Vendor Agreement Clauses to Review

Every business relies on vendors. Software platforms, marketing agencies, IT providers, cleaning services, raw materials suppliers. Each of those relationships is governed by a contract that defines what you get, what you pay, and what happens when things go wrong. Most businesses sign vendor agreements with minimal review because the relationship feels low-risk or the vendor presents the contract as non-negotiable.

The truth is that vendor agreements contain real financial exposure. An uncapped liability clause, a missing SLA, or an aggressive auto-renewal provision can cost more than the entire value of the contract. Here are the ten clauses that deserve the closest attention.

1. Service Levels and SLAs

A service level agreement defines the measurable performance standards the vendor must meet. For technology vendors, this typically includes uptime guarantees (99.9% is common), response times for support tickets, and resolution timeframes for different severity levels.

The SLA is only meaningful if it includes consequences for failure. A 99.9% uptime guarantee without service credits or termination rights is a marketing claim, not a contractual commitment. Look for specific remedies: service credits that apply automatically when SLAs are missed, the right to terminate without penalty after repeated failures, and clear measurement methodology so there is no dispute about whether the standard was met.

2. Liability Caps

The limitation of liability clause sets the maximum amount one party can recover from the other if something goes wrong. Vendors typically cap their liability at the fees paid during the prior 12 months. For a $50,000 annual contract, the vendor’s maximum exposure is $50,000 regardless of how much damage their failure caused.

That cap may be adequate for minor service disruptions but wildly insufficient for a data breach, regulatory violation, or business interruption that costs your company millions. Negotiate higher caps for high-impact scenarios. At minimum, ensure that the cap does not apply to the vendor’s indemnification obligations, breaches of confidentiality, willful misconduct, or IP infringement claims. These carve-outs are standard in well-negotiated agreements.

3. Indemnification

Indemnification determines who pays when a third party brings a claim related to the contract. A vendor should indemnify you against claims arising from the vendor’s negligence, IP infringement in the vendor’s deliverables, and the vendor’s violation of applicable laws.

Watch for indemnification that runs only one way. If you are required to indemnify the vendor but the vendor does not indemnify you, the risk allocation is lopsided. Also check whether the indemnifying party has the right to control the defense of the claim. Losing control of your own legal defense is a significant concession.

4. Insurance Requirements

Indemnification only works if the indemnifying party can actually pay. Requiring vendors to maintain adequate insurance coverage backs up their contractual promises with real financial capacity. Standard requirements include commercial general liability ($1 million per occurrence is common), professional liability or errors and omissions coverage, cyber liability insurance if the vendor handles your data, and workers’ compensation as required by law.

Ask for a certificate of insurance naming your company as an additional insured. This gives you direct rights under the vendor’s policy, not just a contractual promise that insurance exists. Require the vendor to notify you if coverage lapses or is materially reduced.

5. Data Security

If the vendor will access, process, or store any of your company’s data (including employee data, customer data, or proprietary business information), the contract needs a data security provision. This should specify the security standards the vendor must maintain, their obligations in the event of a breach (including notification timelines, typically 24 to 72 hours), and your right to audit the vendor’s security practices.

For vendors handling personal data subject to GDPR, CCPA, or other privacy regulations, a data processing agreement or addendum is required. This is not optional. Regulatory liability for a vendor’s data breach can fall on you as the data controller even if the vendor caused the incident.

6. Payment Terms

Standard payment terms are net 30 (payment due within 30 days of invoice). Some vendors push for net 15 or payment upon receipt, which can strain cash flow. Others include late payment penalties, interest on overdue amounts, or the right to suspend services for non-payment.

Negotiate payment terms that match your billing cycle and cash flow. If you pay vendors monthly but invoice your own clients quarterly, a net 45 or net 60 payment term may be more realistic. Also check whether the vendor can increase prices unilaterally. Many contracts include an annual price increase tied to CPI or a fixed percentage. Others give the vendor the right to change pricing with 30 days’ notice, which effectively makes the price unpredictable from year to year.

7. Change Order Process

The original scope of a vendor engagement almost always evolves. A change order process defines how modifications to scope, timeline, or pricing are requested, approved, and documented. Without one, scope changes happen informally, costs accumulate without approval, and disputes arise about what was included in the original agreement.

A good change order provision requires that all changes be documented in writing, signed by both parties, and include a clear description of the modified scope, revised timeline, and adjusted pricing. It should also state that no work beyond the original scope proceeds until the change order is approved. This protects both parties from unauthorized scope expansion and unexpected invoices.

8. Force Majeure

Force majeure clauses excuse performance when extraordinary events beyond a party’s control prevent them from fulfilling their obligations. Traditional force majeure events include natural disasters, war, government actions, and acts of terrorism. Post-2020 agreements routinely add pandemics, supply chain disruptions, and government-mandated shutdowns.

The key questions are how broadly the clause is drafted and what remedies are available. Does force majeure suspend the vendor’s obligations indefinitely, or is there a maximum suspension period after which you can terminate? Does the vendor have to demonstrate actual inability to perform, or does general economic hardship qualify? A well-drafted force majeure clause includes a cap (typically 60 to 90 days), after which either party can terminate without penalty.

9. Assignment Restrictions

An assignment clause determines whether either party can transfer the contract to a third party. This matters more than most people realize. If your vendor is acquired by a competitor or a private equity firm, the acquiring company steps into the vendor’s shoes and takes over your contract. The team you trusted, the service culture you relied on, and the pricing you negotiated may all change.

Restrict the vendor’s right to assign the contract without your consent. Include a provision that allows you to terminate without penalty if the vendor is acquired or undergoes a change of control. At the same time, ensure that your own right to assign the contract is preserved for internal reorganizations, mergers, or transfers to affiliates.

10. Most Favored Customer

A most favored customer (MFC) clause guarantees that the vendor will not offer better pricing or terms to another customer in a comparable situation. If the vendor gives a 20% discount to a new client with similar volume and scope, your pricing adjusts to match.

MFC clauses are more common in large enterprise agreements but can be valuable for mid-market companies as well. The key is defining what ”comparable” means. Without a clear comparison framework (similar volume, similar scope, similar contract duration), the MFC clause becomes difficult to enforce. The vendor will always argue that the other customer’s situation is different enough to justify the better pricing.
