Assumptions and open questions

• I assumed a character limit of 280 per post. Check your account's limit.
• I used "we" and kept your numbers as given. I added no claims about total revenue, because your notes only give revenue per new customer. Fewer signups at a higher value per customer may or may not net out ahead. If you have the total figure, add it. It would be the first question a founder asks.
• Your notes don't say how long the data covers or whether anything else changed in that period. Add that if you can.

Shape: A thread. It's a trade-off with several numbers and a conditional lesson, which a single post would flatten. Eight short posts.

First-post options

1. A result: "We moved to annual-only billing. Signups dropped about 19%. Here's why we'd still do it again."
2. A contrast: "Annual-only billing cost us about 40 signups a month. It also cut early churn from 9.8% to 6.1%."
3. A plain statement: "In March we dropped monthly plans. Here's what happened, including the part that got worse."

I recommend option 3, which is the plainest. It's used in the thread below, with the numbers following in the next posts.

Thread

1/
In March we dropped monthly plans and moved our SaaS billing to annual-only.

Here's what happened, including the part that got worse.

2/
The downside first.

New signups fell from about 210 a month to about 170.

That's roughly 19% fewer people signing up. The drop is real, and we didn't find a way to explain it away.

3/
What went up: revenue per new customer, by 31%.

4/
Churn in the first 90 days fell from 9.8% to 6.1%.

Fewer people are leaving early.

5/
Support tickets about invoices fell from 120 a month to 45.

Fewer billing cycles means fewer invoices to question.

6/
We also offer refunds within 30 days, no questions asked.

So paying upfront isn't a one-way door for a new customer.

7/
Our lesson: the signup drop was real, but the customers who stayed were a better fit.

We'd do it again.

8/
One caveat. We wouldn't do it for a product with no existing customer base.

If you're considering it, what would you want to know first? Happy to share more detail.

Edit notes

• Post 2: I added "roughly 19%" (calculated from 210→170, about 19.05%). Cut it if you'd rather not add a derived number.
• Post 5: "Fewer billing cycles means fewer invoices to question" is my explanation, not something in your notes. Keep it only if it matches what you saw.
• Post 6: "isn't a one-way door" is my framing of the refund policy. Cut or reword it if it doesn't match your reasoning.
• Dropped any hype words and emojis to keep the voice plain.
• All posts are well under 280 characters.

Extras

• Image: a simple before/after table of the four metrics (signups, revenue per new customer, 90-day churn, invoice tickets). Alt text: "Table comparing monthly billing and annual-only billing: signups 210 to 170 a month, 90-day churn 9.8% to 6.1%, invoice tickets 120 to 45 a month, revenue per new customer up 31%."
• Pinned reply idea: share how you announced the change to existing customers, if you're comfortable doing so.
• Follow-ups: (1) how the 30-day refund policy has worked in practice, if you have the refund rate. (2) What you'd check before switching if you're an early-stage product.

Pre-posting checklist

• Confirm each number against the dashboard.
• Make sure post 8's caveat reflects your actual reasoning.
• Decide whether to add total revenue, since the thread is stronger with it.
