Invoicing US clients the right way protects you at tax time and makes you look professional. This guide covers what belongs on the invoice, when clients ask for a W-9, and how to send invoices from MyCG.AI.
Why the invoice details matter
A US client may need your invoice to match their own tax records. If your invoice is missing your legal name, address, or tax ID, their accounting team may hold the payment until you fix it. Getting the format right the first time keeps payments moving and keeps your own books clean.
What to put on every invoice
Use these fields on each invoice you send to a US client.
- Legal business name. Use the exact name on your formation documents, not a nickname or a shortened version.
- EIN, when the client asks for it. Some clients only need this for their own 1099 filing. Others never ask. Keep your EIN handy but you do not have to print it on every invoice by default.
- US business address. Your registered agent address is for legal service, not for invoicing. Use the virtual business address included in your PowerLaunch plan, or your own US mailing address if you have one.
- Bank details or payment link. If you are paid by wire, include your account and routing numbers. If you invoice through Stripe, a payment link replaces this.
- Invoice number and date. Sequential numbering makes your bookkeeping and any audit trail easier to follow.
- Description of services or goods, and the amount. Be specific. "Consulting services, March 2025" is better than "Services."
- Currency. State that the invoice is in US dollars if there is any chance of confusion.
When a client asks for a W-9
A W-9 is a US tax form that a client uses to collect your legal name, address, and EIN before they pay you or before they issue a 1099 at year end. If a US client requests one, this is normal and does not mean anything is wrong. Fill it out with your LLC's legal name and EIN, sign it, and send it back. Keep a copy for your own records.
If you are a foreign-owned single-member LLC, you still fill out a W-9 the same way using your EIN. The W-9 does not replace your own federal filing obligations, which are separate and covered below.
Invoicing through Stripe and MyCG.AI
Every PowerLaunch Run and Scale plan includes Stripe invoicing set up inside MyCG.AI. Once your EIN and bank connection are in place, you can create and send invoices from the platform, and payments flow into your transaction feed with AI categorization already applied. This saves you from re-entering the same invoice data into a separate bookkeeping tool later.
| Task | Launch plan | Run plan | Scale plan |
|---|---|---|---|
| Stripe invoicing | Not included | Included | Included |
| Transaction tracking with AI categorization | Not included | Included | Included |
| Live financial reports | Not included | Included | Included |
| Dedicated bookkeeper | Not included | Not included | Included |
If you are on the Launch plan and want invoicing built into your finance platform rather than a separate tool, upgrading to Run adds this along with transaction tracking and closings.
Keeping invoice records for tax time
Every invoice you send is part of your income record for the year. If you are a foreign-owned single-member LLC, your invoices and bank records feed directly into your Form 5472 and pro forma 1120, which are due by April 15. These forms report transactions between your LLC and its foreign owner, so clean, dated invoices make this filing much faster to prepare. A licensed tax professional consultation is included on the Run and Scale plans if you want help matching your invoice records to your filing.
BOI reporting is a separate requirement from invoicing, and under the current 2026 interim FinCEN rule, US-formed companies are exempt. Rules can change, so check FinCEN's site if you want the latest position before you file anything.
Common invoicing mistakes to avoid
- Using your registered agent's address instead of a real business address. Clients sometimes flag this during their own compliance checks.
- Leaving off the invoice date or number, which makes it harder to reconcile payments later.
- Sending a W-9 with a personal name instead of the LLC's legal name. The IRS matches these records, so consistency matters.
- Mixing currencies without saying so. If you ever bill in anything other than US dollars, state it clearly, though most PowerLaunch clients invoice in US dollars only.
- Forgetting to update your invoice template after a bank change. If you move to a new banking partner, update your payment details on every future invoice right away.
