What every invoice must include
A professional invoice is a clear request for payment. Whether you write it by hand or generate it automatically, every invoice should contain the same core information so your client knows exactly who to pay, how much, and by when.
- The word “Invoice” and a unique invoice number
- Your business name, address, and contact details (and logo, if you have one)
- Your client's name and billing address
- The invoice date and the payment due date
- An itemized list of products or services, with quantity, unit price, and line total
- Subtotal, any tax (such as VAT or sales tax), discounts, and the final total due
- Payment terms and accepted payment methods or bank details

Tips to get your invoices paid faster
How you build and send an invoice has a real effect on how quickly you get paid. A few small habits make a big difference:
- Set clear, short payment terms (for example, “due within 14 days”) and state them on the invoice.
- Use sequential invoice numbers so both you and your client can reference them easily.
- Send the invoice promptly from your own email address so it looks professional and lands in the right inbox.
- Itemize the work clearly so there are no questions that delay payment.
- Automate reminders and repeat invoices — with Invco's Claude (MCP) integration you can even ask your AI assistant to create and send them for you.
Frequently asked questions
What information do I need to create an invoice?

How do I number my invoices?
Use a simple, sequential scheme such as INV-0001, INV-0002, and so on. Invco handles recurring invoice numbering automatically so your records stay consistent and every invoice has a unique number.
