Holden Oliver at What About Clients? exhorts us to proofread our invoices and everything else that our clients read. Why? Because the reader is the client.
He also reminds us that “invoices, if done correctly, are a great way to communicate what you've done for a client and they can even serve as a marketing tool.” If we’re trained in persuasive writing, then we ought to apply that training to our time entries—and just about everything else we write.
