Another all-in-one ERP alternative competing with Odoo and Dolibarr.
Running invoices, contracts, payments and time-tracking from WhatsApp flips the usual app-first workflow and feels immediately useful for people who hate dashboards. The build looks thoughtful: persistent memory, cron automation, browser automation and custom skills on top of OpenClaw sew a believable agent layer — the question is whether those "79 tools" are deep integrations or surface wrappers.

The author's cost optimization — swapping to Sonnet 4.6 to drop agentic task costs from ~$0.15 to ~$0.04 — is a pragmatic win, but the live site shows a runtime error ('Cannot read properties of undefined (reading "cache")'), and it's not yet obvious how this will out-compete entrenched invoicing/contract tools.
