What we typed
An advertorial: an article-style pre-sell page built around one reader question, why do my clients keep paying late? Write it like a practical piece in a newsletter for freelancers. Near the top, label it clearly as sponsored content from Billwick. The first half explains five everyday reasons invoices get paid late (no clear due date, missing details the client's accounts team needs such as a purchase order number, the invoice going to the wrong person, nobody following up, and paying being awkward for the client), with a fix for each that readers can apply to their next invoice with any tool. Only in the second half, introduce Billwick as one option: invoices with all the details in one place, polite automatic reminders, and card or bank-transfer payment from the invoice itself, from $12 a month, with a 14-day free trial and no card needed to start. No legal, tax or financial advice, and no invented studies, statistics, reviews, quotes or expert names. Main action: Start your free trial. In the footer, add one line: Billwick is a demo brand created to show what Octet Prow can build. It is not a real company and nothing here is for sale.

How the page is put together
- OpeningWhy do my clients keep paying late?The sponsored label, the question and a contents box. No product yet.
- 01Reason 01 — “Net 30” is a suggestion. A date is an instruction.Reason one: a payment term instead of a date.
- 02Reason 02 — An invoice with a blank PO field is an invoice that can't be processed.Reason two: details the client’s accounts team needs, with an example invoice.
- 03Reason 03 — The person who approved your work is not the person who releases payment.Reason three: the invoice goes to the wrong person.
- 04Reason 04 — An unchased invoice becomes an unpaid invoice. That's not cynicism, it's volume.Reason four: nobody follows up, with three sample reminder emails.
- 05Reason 05 — Bank details in a PDF footer is a five-step chore you're asking someone to do.Reason five: paying is a chore for the client.
- 06Billwick, if you'd rather not remember any of this.The app, introduced as one option that handles all five.
- 07What a Billwick follow-up actually looks like.What the automatic reminders look like.
- 08Start your free trialThe price, the free trial and the single action.
- 09The five fixes, on one page.The five fixes again as a list readers can keep, without the product.
What we checked and changed
We removed a trial button from the header so the app appears only in the second half, an invented issue number, an invented figure (“thirty other vendors”) and several claims about what most clients and freelancers do. One correction took two requests: the first time, the editor reported the change but left the line as it was. We also asked for images, one at the top and one per reason.
