Security Scan

The skill is an instruction-only invoicing/template helper but it claims automated tracking and reminders while asking for no credentials or integrations — that's a mismatch that could mislead users.

Purpose & Capability

Name/description promise a full 'billing lifecycle' including automated reminders, payment tracking, and reconciliation. However, the skill is instruction-only (no code, no install, no required env vars or credentials). As written it provides templates and procedures but no built-in integrations with payment processors, email providers, or accounting systems. The advertised automation is therefore aspirational rather than implemented; this is a coherence/expectation mismatch but not clearly malicious.

Instruction Scope

SKILL.md contains invoice templates, status categories, aging reports, and reminder/communication examples. The instructions do not direct the agent to read local config files, environment variables, or external endpoints, nor do they instruct credential access or data exfiltration. The scope stays within creating documents and message templates.

Install Mechanism

No install spec and no code files — the skill is instruction-only and will not write or execute code on disk. This is the lowest-risk install posture.

Credentials

The skill requests no environment variables, credentials, or config paths. That is proportionate for a templates-and-procedures skill. Note: if a user expects real automation (sending reminders, reconciling payments), they will need to provide external credentials or connectors externally; the skill itself does not request them.

Persistence & Privilege

always is false and there is no code that requests persistent presence or modifies other skills or system settings. The skill does not ask to store or manage secrets on the agent.

What to consider before installing

This skill is a templates-and-processes helper — it produces invoice layouts, reminder text, and reconciliation procedures but does not itself send emails, connect to Stripe/PayPal, or access accounting systems. If you expect automated sending or payment reconciliation you will need to provide separate integrations (email provider, payment processor, accounting software) and corresponding credentials; the skill does not request or store those. Before using: (1) Don’t paste real account credentials or secret keys into prompts or generated text. (2) Understand that promised "automated reminders" are examples only unless you wire up your own integrations. (3) If you need true automation, prefer a skill that explicitly documents required integrations, where credentials are stored, and how data is transmitted. Given the mismatch between advertised automation and the instruction-only implementation, proceed only if you understand the manual nature of this skill or plan to add secure integrations yourself.

Best Practices

Invoice Numbering

Use a consistent format:

• INV-YYYY-NNN (INV-2024-001)
• YYYY-MM-NNN (2024-01-001)
• CLIENT-NNN (ABC-001)

Payment Terms

Standard options:

• Net 15: Large enterprises (they take forever anyway)
• Net 30: Standard for most clients
• Due on receipt: Small projects, new clients
• 50/50: 50% deposit, 50% on completion
• Milestone: Payment at defined project stages

Cash Flow Tips

1. Invoice immediately — don't wait until month-end
2. Require deposits — 50% upfront for new clients
3. Offer early payment discounts — 2/10 Net 30 (2% off if paid in 10 days)
4. Charge late fees — and enforce them
5. Stop work on overdue accounts — protect yourself
6. Use online payments — easier for clients = faster payment

Red Flags

Watch for these warning signs:

• Client questions your rates after agreement
• "The check is in the mail" (repeatedly)
• Asks to pay after project completion (no deposit)
• Disappears when invoice is due
• Wants to change payment terms mid-project

Tools Integration

Accounting Software:

• QuickBooks, Xero, FreshBooks — sync invoices
• Automatic reconciliation
• Tax reporting

Payment Processors:

• Stripe — credit cards, ACH
• PayPal — widely accepted
• Wise — international transfers
• Bank transfer — lowest fees

Time Tracking:

• Harvest, Toggl, Clockify
• Auto-generate invoices from time entries

Common Mistakes

1. Not invoicing promptly — delays payment by weeks
2. Unclear payment terms — confusion leads to delays
3. No late fees — clients have no incentive to pay on time
4. Ignoring overdue invoices — they don't get better with age
5. No deposit for new clients — high risk of non-payment
6. Mixing personal and business — tax nightmare
7. Not tracking 1099s — IRS penalties

Integration Ideas

• Connect to proposal-generator to convert accepted proposals to invoices
• Use with client-intake-bot to set payment expectations upfront
• Track project profitability alongside content-repurposer ROI

Monetization Note
