Same request, same model, once with the skill and once without. Read both and judge for yourself.

“Write a short email telling our customers we're raising the Pro plan price, and why.”

Source material given with the request

Product: Ledgerline, bookkeeping software for freelancers. Pro plan goes from $12 to $15 per month on March 1, 2027. First increase since 2022. Reasons: payroll features added in 2026 and higher card-processing fees. Current customers keep $12 until June 1, 2027.

with the skill

**Subject:** Pro plan price changes March 1, 2027 Hi [First name], We're raising the Ledgerline Pro plan from $12 to $15 per month on March 1, 2027. This is our first increase since 2022. We're raising it for two reasons. We added payroll features in 2026, and card-processing fees have climbed. The extra $3 a month helps cover both. As a current customer, you keep the $12 rate until June 1, 2027. Starting then, we'll bill you $15 per month. You don't need to do anything. If you have questions, reply to this email and our team will answer. Thank you for using Ledgerline. The Ledgerline team

without

**Subject:** An update to Ledgerline Pro pricing Hi [First name], We're writing to let you know that the price of the Ledgerline Pro plan will increase from $12 to $15 per month, starting March 1, 2027. This is our first price increase since 2022. Two things are behind it: the payroll features we added in 2026, and the higher card-processing fees we now pay on every transaction. The new price lets us keep improving Ledgerline and cover those costs. As a current customer, you'll keep your $12 rate until June 1, 2027. Your first bill at $15 will come after that date, and you don't need to do anything to stay on your plan. If you have questions or want to talk through your options, just reply to this email. We're happy to help. Thank you for being part of Ledgerline. Best, The Ledgerline Team
