Drafting Customer Contracts That Protect Your Margin and Limit Your Liability
The five clauses every SME customer contract needs — and the three that most SMEs are missing
Who this is for
SMEs that use informal purchase orders, email confirmations, or customer-drafted contracts as the basis for their commercial relationships. Businesses that have experienced payment disputes, scope creep, or liability claims where the contract did not provide adequate protection.
What it costs you to ignore it
The diagnosis behind it
This playbook is triggered by a Red or Critical finding on:
Vital 8 — Contracts & LegalThe Protocol
Engage a commercial lawyer to draft a standard customer contract template for your most common transaction type. This is a one-time investment — a well-drafted template is used for every customer engagement thereafter.
Ensure the contract defines scope with precision: what is included, what is explicitly excluded, what constitutes a change order, and what the process is for approving and pricing changes. Scope creep is the most common source of margin erosion in service businesses.
Include a payment terms clause that specifies: invoice date, payment due date (net 30 maximum), interest on late payment (1.5–2% per month), and your right to suspend services for non-payment after 15 days. These terms must be in the contract — not just on the invoice.
Include a liability cap: your total liability under the contract should be capped at the value of fees paid in the preceding 3–6 months. Exclude liability for indirect, consequential, or punitive damages. Without this clause, a single contract dispute can threaten the entire business.
Include an IP ownership clause: any work product, software, or deliverable created under the contract is owned by the customer only upon full payment. Until payment is received, IP remains with your business. This gives you leverage in payment disputes.
Train your sales and account management team on the contract: what can be negotiated, what cannot, and who has authority to approve deviations. A contract template that the sales team routinely bypasses provides no protection.
What you can do yourself vs what needs help
Step 1 requires a commercial lawyer — this is not a template you should draft yourself or download from the internet. Steps 2–6 are internal once the template exists. The legal fee is a one-time cost; the protection it provides applies to every contract you sign thereafter.
