## Why invoicing feels more complicated than it needs to be

There are entire books about invoicing. Most of them are written for accounting firms or large businesses with complex billing needs.

For a solo service business, invoicing is simpler. You do a job, you send a bill, you get paid. The goal is to make that last step happen as quickly as possible.

## What every invoice needs

At minimum, a professional invoice should include:

1. **Your name and contact information**: so the client knows who to pay
2. **The client's name**: personalizes it and confirms it's for them
3. **Invoice number**: for tracking and reference
4. **Date issued and payment due date**
5. **Description of the work**: what did you do?
6. **Amount**: be specific (hourly rate × hours, or flat project fee)
7. **Payment instructions**: how can they pay?

That's it. You don't need a long legal block or complex terms for most service work.

## When to send the invoice

The best time to send an invoice is immediately after the work is complete. Not at the end of the week, not at the end of the month, right away.

Why? The service is fresh in the client's mind. They experienced the value. Sending the invoice immediately while the positive experience is recent gets you paid faster.

If you're working on a project, consider sending the invoice with a deposit at the start (to secure commitment) and the final balance at completion.

## How to get paid faster

A few small things make a real difference:

**1. Include an online payment link.**
If the client has to call you, write a cheque, and mail it, they'll delay. If they can pay online with their card in 30 seconds, most will do it immediately.

**2. Be specific about the due date.**
"Due upon receipt" is vague. "Due within 7 days" is specific. Specific due dates get paid faster.

**3. Send a friendly reminder for overdue invoices.**
Most late payments aren't malicious, the client just got busy and forgot. A polite reminder email usually resolves it quickly. Morgan AI lets you send this in one tap.

**4. Offer to collect payment in person.**
For in-person service businesses, the easiest invoice is no invoice at all, just Tap to Pay after the session. If payment is expected immediately after service, there's no invoice to chase.
