Sort vendor invoices out of the inbox without paying one by accident

A free weekly routine for solo operators, plus a one-time skill file for the agent you already use. It separates vendor invoices, client asks, and noise, then drafts a five-line digest and replies. It never sends email and it never pays a bill.

The pile

Bills, client questions, and newsletters share one inbox
A “past due” note and a real invoice look the same until you open them
An automatic “we got your invoice” reply can confirm a bill you have not checked
You want the boring pass handled, not a second bookkeeping app

What you get

Read the free guide and run one 20-minute pass by hand
If the labels stick, drop the paid SKILL.md into your agent
The agent drafts a digest and replies. You send and you pay, somewhere else

Price hypothesis: $29 one-time for the skill file. The guide stays free. This is not a subscription.

Not legal, tax, or accounting advice. Ironwood Labs is not a bookkeeping product. Classifying mail and drafting a digest does not decide whether an invoice is valid or whether you should pay it. The skill must not send email, pay invoices, or store card or bank numbers. You remain responsible for what you send and what you pay.
