EMAIL 1 — The Opener Subject: 4 hours, every month, gone Hi Jordan, Going through your recent post about "the parts of running a consulting business nobody warned me about" — invoicing made the list. That hit because I see the same thing across every solo consultant I talk to: 3 to 5 hours monthly that should have been billable. Quick question — when a client pays late, do you usually catch it in the moment, or find out at the end of the month? — Sarah EMAIL 2 — The Value Drop (Day 3) Subject: re: 4 hours, every month, gone Saw a stat last week from Freshbooks: solo consultants who automate their invoicing get paid 11 days faster on average. Eleven days. That's an extra month of cash flow per year. Sharing in case it's useful. The mechanism is mostly automated reminders triggered when invoices hit specific aging thresholds without you ever lifting a finger. If you ever want to see how a few clients of mine set this up, just reply. — Sarah EMAIL 3 — The Pattern Interrupt (Day 7) Subject: A weird question What does your collections process look like when a client is 30 days late? I ask because most consultants tell me there isn't one — they just send a nervous follow-up email and hope. I have a template that's worked for 200+ solo founders in your exact spot. Want me to send it? — Sarah EMAIL 4 — The Honest Close (Day 12) Subject: Last note Hi Jordan, This is my last message. We built InvoiceFlow specifically for solo consultants tired of the invoicing tax — automated invoices, reminders, and Stripe payments all in one place. If invoicing ever becomes a priority, we offer a 14-day free trial extended to 30 days for founders who reply to this email. No pressure either way. Wishing you a strong quarter. — Sarah ALTERNATIVE SUBJECT LINES FOR EMAIL 1: 1. "Saw your post" 2. "The 4-hour invoicing problem" 3. "About what you mentioned"
