Everyday Business Automations

Three small, standalone automations built to prove that not every workflow needs to be a big system: a contact form that notifies and auto-replies, an invoice reminder that chases overdue payments, and a review-request automation that follows up after a job is done.

01

The Challenge

Most small businesses don't need an elaborate system — they need the basics handled reliably: a contact form that doesn't go into a void, invoices that get chased without someone having to remember, and a way to ask happy customers for a review before the moment passes.

02

The System

We built three independent n8n workflows, each doing exactly one job well and following the same lightweight pattern — trigger, decide, act, nothing extra: contact-form notify + auto-reply, staged invoice payment reminders, and post-job review requests two days after completion.

03

Guardrails

Each workflow does one clearly bounded job.

Sent-state updates prevent repeated messages.

Source sheets remain readable and editable by the business.

Let's build something people actually use.
