The problem

Small-business payment commitments get scattered across conversations, spreadsheets, and memory. A reminder can tell you when to act; a useful workspace also helps you remember the relationship and what was promised.

My role

Independent product builder. I designed a payment-promise workspace that connects commitments, follow-ups, partial payments, revised dates, and broken-promise history.

Approach

The public product presents a contextual message-drafting workflow: choose the conversation goal and tone, then review a draft grounded in the recorded promise. The owner retains control of the conversation and reviews the message before use.

Current status

An accessible early product with a public demonstration and a PeerPush listing. The landing page demonstrates follow-up drafting and the use of promise history. This portfolio makes no adoption or revenue claims.

Constraints

Payment conversations combine factual precision with social context. The product direction keeps amounts, dates, and references grounded in the ledger while leaving the final wording to the business owner. Current cloud-provider implementation is not asserted here.
