Best Practices for Square Invoices

Square Invoices are a great way to bill your customers without having to worry about entering in your customer’s payment card information. However, this gives you less visibility into how your customer is paying, so we recommend following these best practices.

Know your customer.

You’re in control of sending a Square invoice, so it’s important to know who you’re working with. Take additional steps to call your customer for large or unusual orders. If your customer is unable to speak on the phone or the phone number they provide doesn’t work, don’t proceed with a sale.

Send invoices directly to your customer’s email.

Doing this ensures that the customer accepts and recognizes each payment that is processed, reducing the likelihood of a dispute. If you want to keep a copy for your records, you can always cc your own email address.

Attach a Contract

One of the best ways to avoid misunderstandings or late payment is to put a contract in place. Contracts allow you and your customer to understand exactly what is expected from your transaction, minimize your chance of a dispute, and help ensure that you get paid.

If you are using Square Invoices to get paid, you can attach a contract right to your customer’s invoice. While contracts aren’t appropriate for every business, they can be invaluable to businesses who work in wholesale or on a project basis.

Using Square Invoices, you can attach a copy of your contract directly to your customer’s invoice.

If you aren’t familiar with creating a contract, our team has created a few contract templates you can use.

Review multiple attempts to pay an invoice.

Your customer has a few attempts to pay an invoice. For your protection, Square cancels an invoice if the customer reaches a maximum number of attempts. If you receive this messaging, we strongly recommend verifying your customer’s identity, seeking an alternate method of payment such as check or cash, or declining to complete the sale.

Be cautious of in-person pickups.

If someone is requesting to pay by Square Invoice but wants to pick up product or receive services in-person, this could be a sign your customer is using stolen card information. Verify the last four digits of the card by heading to Sales in your Square Dashboard and then selecting Transactions. Select the payment in question to see the card type and last four digits. Ask to see a copy of the card and the customer’s identification when you meet him or her in person.

You also have the option to request your customer to pay their invoice in person.

Be cautious of requests for immediate or expedited shipping.

Additionally, check to see if the shipping address makes sense for your buyer’s order. Mail drop locations such as UPS stores and freight forwarders are commonly associated with fraud and we do not recommend shipping to them. If you receive an order from someone claiming to be a business, but the customer requests shipping to a private or residential address, this could also be a sign of fraud.

Include your terms of service and any estimated delivery times.

Make sure your customers are aware of your policies at the time they submit their payment. To help prevent any potential disputes in the future, include the following information in the body of an invoice:

  • refund policy
  • cancellation policy
  • terms of service
  • estimated delivery times
