"Why did my client reject my invoice?" That is the question we hear most often. We write about the billing problems we encounter ourselves: which tax fields an invoice needs in the EU versus the US, how to format invoice numbers so they sort correctly in a folder of 500 bills, and what happens when a client's AP team rejects your format. No fluff, no generic advice — just what actually works.
Recent posts cover the EU e-invoicing mandate timeline, UK Making Tax Digital changes, and a comparison of PDF invoice generators — including what we learned building ours. One user wrote to us after reading our post on VAT number formats, saying she had been entering her client's VAT number incorrectly for six months and had three invoices rejected because of it. She fixed the format after reading the article and has not had a rejection since.
We update the blog every few weeks based on questions from users and changes in tax regulations. If there is a topic you want us to cover, send us a message and we will add it to our editorial calendar. Each article is written from a practitioner's perspective. Recent topics include: • How to handle late payment follow-ups without damaging client relationships • The exact fields a US freelancer needs on an invoice for a UK client • Why your invoice number format matters more than you think — and how to fix it. Bookmark the blog index and check back periodically. The articles are designed to be read in any order, so start with whatever challenge is most pressing for your business today.
