What should I know about The invoice is not the problem. The follow-up is.?

Sending the invoice is easy. Getting paid is a follow-up loop. Free Builder treats that loop as a system, not a mood.

In the 3-week program you wire the whole path: checkout, invoice, a follow-up sequence, and a place for replies to land. AI workers send the first, second, and third touch. You write the tone once. It runs in your voice while you sleep.

Here is the loop to set up:

1. Sell something clear. One offer, one price, one checkout link.
2. Wire payments into the MERN scaffold so paid and unpaid states are visible.
3. Write three follow-up messages in your voice: day 1, day 3, day 7.
4. Route replies to one inbox, AI or Intercom, so nothing rots.
5. Review the numbers weekly. Direct changes. Repeat.
