Once connected, Grok Build can:
- Draft invoices, estimates and credit notes for your customers, with the totals worked out for you.
- Turn an estimate into an invoice, and repeat an invoice on a schedule, such as a monthly retainer.
- Email an invoice or a payment reminder to your customer when you tell it to.
- See who owes you and how late each invoice is, and record the payments you receive.
- Add customers and saved items, and set up your taxes and payment options from the details you give it.

Grok Build and LotsInvoice: questions
How do I connect Grok Build to LotsInvoice?

Does LotsInvoice work with Grok Build?

Do I need an API key to use LotsInvoice with Grok Build?
No. Grok Build signs in to LotsInvoice in your browser. API keys are for the REST API, for scripts and your own apps.
What does LotsInvoice cost?
Current plans and prices are on https://lotsinvoice.com/pricing. Your agent’s own plan or usage fees are separate.
Will my agent email my customers without asking me?
Every invoice starts as a draft, and nothing reaches your customer until it is sent. Sending is its own step, and the LotsInvoice tools and skill tell your agent to show you the totals and ask before it sends. You can also open the draft in your dashboard first.
Does LotsInvoice take or move money through my agent?
No. LotsInvoice never holds or moves your money. Your customers pay you directly with the payment options you set up, and your agent can record a payment once you have received it.
Can my agent change an invoice I already sent?
A sent invoice is locked with its number. Your agent can revise it with a reason, which keeps the number and adds a version, or void it. A paid invoice is corrected with a credit note.
Does my agent choose my tax rates?
No. It uses the taxes you have set up or the rates you give it, and it asks for anything that is missing. Check your layout and tax wording with your accountant.
LotsInvoice tools are not available
Check that LotsInvoice is enabled for this session and authentication has completed. Reload the connection or start a new session to refresh its tools.
