Start with the evidence
Compare the customer name with the accepted agreement or order. Keep the contact person in a separate field or note so that a friendly email signature does not replace the intended recipient.
Work through the example
In the example, Maya is the contact and Example Studio is the customer. The two labels answer different questions. Check the spelling against the source rather than copying an abbreviated name from an old message.
Make the next step clear
Retain the source used to confirm the recipient and ask about any conflict before release. If an existing invoice needs correction, preserve its reference and follow your established correction process rather than silently editing the record.
Keep the source context
Treat an invoice draft as a description of an agreed business event. Keep the source agreement nearby and distinguish document preparation from approval, sending and receiving payment. These are separate steps even when they happen close together.
