# Connect Manus to LotsInvoice

Canonical page: https://lotsinvoice.com/agents/manus
Steps checked: 2026-10-01

Ask Manus to draft invoices, check who owes you and record payments in LotsInvoice. Add LotsInvoice to Manus as a remote MCP server and sign in once.

MCP server URL: https://api.lotsinvoice.com/mcp
REST API docs: https://api.lotsinvoice.com/docs
Setup instructions for your agent: https://lotsinvoice.com/skill.md

## What you can do once connected

- 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.
- Pull revenue, tax and payment reports and customer statements for your accountant.

The LotsInvoice dashboard does the whole job on its own: invoices, estimates, customers, payments, reminders and reports. Every invoice your agent drafts shows up there, where you can check the PDF preview before you send it.

## You need

- Manus with custom MCP connectors available
- A LotsInvoice API key or an available OAuth connection
- A LotsInvoice account. You can create one during sign-in.

## Connect Manus to LotsInvoice

1. **Add a custom server.** Open Settings → Integrations → Custom MCP Servers → Add Server. Name it LotsInvoice and enter this URL.

```
https://api.lotsinvoice.com/mcp
```

2. **Authenticate.** Use OAuth sign-in if offered. For a Bearer-token connection, create a LotsInvoice API key at https://www.lotstech.com/api and add it in the connector’s credential field.

```
Authorization: Bearer <your API key>
```

3. **Check the tools.** Ask your agent “Show me what needs attention in my LotsInvoice business” before asking it to change anything.

## What to ask next

- “Draft an invoice for Acme Design for 12 hours of design work, due in 15 days. Show me the total first.”
- “Which invoices are overdue? Show me a friendly reminder for each one before you send anything.”
- “Turn the estimate for Northwind into an invoice and set it to repeat on the 1st of every month.”
- “Record a bank transfer from Northwind against their open invoice.”

## Questions and troubleshooting

### How do I connect Manus to LotsInvoice?

Follow the Manus setup above to add https://api.lotsinvoice.com/mcp. Complete sign-in using the authentication method shown. Then ask “Show me what needs attention in my LotsInvoice business”.

### Do I choose LotsInvoice from Manus’s official connector list?

The route here is a custom MCP server. Add LotsInvoice as a custom server in Manus’s integration settings and authenticate with your LotsInvoice account or API key.

### Do I need an API key to use LotsInvoice with Manus?

Only if the connector asks for one. Create one at https://www.lotstech.com/api and keep it out of chats, logs and committed files. Where Manus offers sign-in, use that instead.

### 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.
