Prepay Chargeback Defense SOP for Solo SaaS

Overview

Canonical sourcing log: /Users/xiaoyinqu/onepersoncompany-deploy/automation/reports/daily-skill-sourcing-log-2026-04-03.md

Overview

If you run a solo SaaS, annual prepay looks like a win until one payment gets disputed. A single disputed invoice can lock funds, create support overhead, and force reactive policy decisions under pressure.

This skill gives you a practical SOP to reduce dispute probability before payment, and to respond with strong evidence if a dispute still happens. The focus is not legal theory. The focus is cashflow protection for one-person operators.

For one-person companies, this is a survivability workflow. When revenue concentration is high, payment reliability matters as much as top-line growth.

When to Use This Skill

- You sell annual or multi-month prepay plans - You process larger invoices where one dispute materially affects runway - You want clearer refund boundaries and acceptance proof - You have no standardized dispute evidence packet

What This Skill Does

- defines prepay-safe billing terms and acceptance checkpoints - standardizes proof collection before fulfillment - creates a reusable dispute evidence packet - sets response timing and communication rules - introduces a prepay risk gate for high-risk buyers

How to Use

1. Define prepay-safe terms before payment. Include refund window, delivery milestones, service start point, and cancellation boundaries in plain language.

2. Capture explicit acceptance proof. Store timestamped proof for terms acceptance, invoice scope, buyer identity, and delivery start trigger.

3. Standardize fulfillment logging. Track delivery artifacts (account provisioning, milestone completion, support actions) in one timeline.

4. Build the dispute evidence packet in advance.

Create a single folder that always includes:

• - invoice and payment record
• - accepted terms snapshot
• - scope and deliverable agreement
• - fulfillment timeline and support logs
• - customer communication extracts

5. Add a prepay risk gate. Score new buyers before accepting annual prepay. Route high-risk accounts to monthly plans first.

6. Define a response SLA and owner checklist. Set a same-day first response target and a fixed submission checklist so you never start from scratch.

7. Audit monthly. Review disputes, refunds, and near-misses. Update policy language where ambiguity repeats.

Output / Result - reduced exposure to avoidable prepay disputes - faster, cleaner dispute responses - clearer billing boundaries for customers - more predictable cashflow for a solo operator

Common Mistakes to Avoid - vague annual-plan refund language - no explicit acceptance proof before fulfillment - collecting evidence only after a dispute begins - accepting annual prepay for every new buyer without risk screening - treating payment risk as a support issue instead of an operating system
