Founders pay for AI implementation, then discover a critical item is missing from the invoice. This wastes time and money. A checklist helps verify the invoice before payment so you don't pay for unclear services.

## TL;DR
- Confirm the invoice clearly states what's included in the service.
- Ensure there are terms about ownership of results and code.
- Clarify if there's a result guarantee and how it's documented.

### Does the invoice specify concrete outcomes, not just tool access?
The invoice should describe what you'll receive for your money: training, created automations, access to materials. If it only says "AI services" or "platform access" — that's a red flag. You need to know how many live sessions there are, whether there's a recorded course, and if support is included. Without this, you're paying for the undefined.

### Is it stated who owns the created code and automations?
The invoice must include a clause transferring rights to the code, scripts, and configurations. If it's missing, you risk losing access to the results after the contract ends. This is especially important if you plan to scale automations without the vendor's involvement.

### Does the invoice describe how results will be measured and whether there's a guarantee?
The guarantee must be described in writing: what specific outcome is promised (e.g., minimum 3 working automations), how it's verified, and what happens if the result isn't achieved. Without such fixation, the word "guarantee" is just marketing.

### Is the cost broken down into line items so you see exactly what you're paying for?
A good invoice shows: payment for the training program, for creating automations, for support, and for materials. This lets you compare with other offers and understand if the cost matches the scope of work.

### Are execution timelines for each stage specified and what each includes?
The invoice should indicate when training starts, when to expect first results, and how feedback will be handled. This helps you plan company resources and track progress.

> **Definition:** A working automation is a tool that executes an agreed-upon scenario on your company's data in your systems — not a demo or test example.
> **Definition:** A result guarantee is the vendor's written commitment to refund money or fix the situation if a pre-defined outcome is not achieved.
> **Definition:** Code ownership means the company has the right to use, modify, and distribute the created code without restrictions or additional payments.

## FAQ
**Is an NDA with the vendor mandatory in the invoice?**
If you plan to use real company data during training, it's worth including an NDA or a clause about using test data. This protects your trade secrets.

**Can the price change after signing the invoice?**
A fixed price stated in the invoice must be final. If the terms allow changing the amount without your consent — that's a risk to eliminate during negotiations.

**Should the invoice list which specific AI models will be used?**
Not required, but useful to know whether it's open-access models or commercial APIs, as this affects data security and future costs.

> **How this works on our side:** Our corporate program includes 4 live sessions of 2 hours each, a recorded course, creation of at least 3 working automations on your company's priority tasks with a money-back guarantee. Code and automations are yours — first month of support is included. https://course.aiadvisoryboard.me/corporate?utm_source=blog&utm_medium=article_body&utm_campaign=corporate

## Conclusion
Before payment, audit the invoice for clear description of outcomes, code rights, and guarantee. Tomorrow, set aside 15 minutes to run through this checklist on the last AI service invoice you plan to pay.
