This is a pack of five n8n workflows for service businesses, sold as a digital product on Gumroad under the headline 'Stop doing client admin by hand'. It is aimed at clinics, salons, studios and contractors that run n8n themselves, and at agencies and freelancers who set up n8n for them.
The price is $39. The Gumroad page shown to us was brief, so check the listing for what each workflow does and what you need to run them.
The pack is aimed at small service businesses that want to cut down on manual client admin.
