Retainer clients should pay for the month before it starts, not 30 days after it ends.

For US consultants and agencies on monthly retainers: invoice around the 20th for next month, due by the 1st. Say on the invoice what the month covers (hours or deliverables) and what happens to unused hours.

Net 15 and Net 30 only help if the client can see them on the invoice.

For US consultants and agencies: write the term and the due date on every invoice, then keep every reminder pointing at that same date. No "whenever you can" wording. No new deadline in the chase email.

Most overdue emails fail because the client still has to hunt for how to pay.

For US consultants and agencies: put one pay link in every reminder. Same thread as the invoice. Invoice number, exact amount, original due date, then the link. No scavenger hunt through old PDFs.

You do not need QuickBooks or Xero open to chase an unpaid invoice.

For US consultants and agencies who live in email and client work, not the accounting tab: create or upload the invoice in Tallylark, send one pay link, and let Early / due / +7 / +14 run so you stay the professional one.

Busy running the business, not chasing invoices?

Photo or upload an invoice from email or PDFs. Fields fill in. Send a pay link, then let a polite-then-firm reminder sequence run so you stay the professional one and get back to client work.

Still digging invoices out of email and PDFs before you can even chase payment?

On Tallylark you can photo or upload an invoice. Fields fill in. Send a pay link, then let the polite-then-firm sequence run so you stay the professional one.

Net 15 and Net 30 are not the same cash-flow decision.

For US freelancers and agencies, Net 15 can cut days sales outstanding. Net 30 can win the deal when the client will not budge. Pick on purpose, put it on the invoice, and stick to it.

No Xero or QuickBooks required to start.

Tallylark is for consultants and agencies who still chase invoices by hand. Create or upload an invoice, send a pay link, and let a polite-then-firm reminder sequence run so you stay the professional one.

Early. Due. +7. +14.

That is the reminder sequence Tallylark sends after you send an invoice, so you are not writing another awkward follow-up by hand.

Hey PH community, I'm building Tallylark (automated invoice reminders for freelancers, $9/mo) and following a validation-first approach before writing a line of product code.

The problem: freelancers lose 102 hours/year chasing late invoices. Every existing tool (InvoiceSherpa, Chaser) costs $49/mo+ and is built for finance teams, not solo operators sending 10-15 invoices a month.

What I've done so far:

• Landing page live at tallylark.com

• Waitlist running with referral system

• Posting in freelance communities to test messaging
