The commercial stack every post-ship founder needs

You shipped. Someone paid you. Congratulations, you are now running a business.

The problem is that most of the infrastructure for running a business assumes you already have it set up. It does not tell you what to set up first, in what order, or how to wire it all together. It just exists, waiting for you to figure it out.

Here is the short version of what you actually need, and when.

From your first paying customer

A contract. Not a PDF you emailed. A proper signed agreement with a clear scope, payment terms, and IP ownership. BoldSign and PandaDoc both do this. Pick one and use it from day one.

A way to invoice and get paid. Stripe for most founders. Xero or QuickBooks once you need proper accounting visibility. Set up Stripe first, connect it to your accounting tool second.

A CRM. Even a basic one. The moment you have more than three conversations in progress, you will lose track of something. HubSpot has a free tier. Attio is cleaner for early-stage. The tool matters less than the habit of using it.

Within your first month

A single source of financial truth. You need to know your MRR, your runway, and your burn. Not from memory. From a system. This does not need to be complicated. It needs to exist.

An email setup that is not your personal Gmail. A company domain, a shared inbox for support, and an outbound sequence for new signups.

A way to track what is happening. PostHog for product analytics. Something simple for revenue. The founders who make good decisions early are the ones who built the habit of looking at numbers.

Within your first three months

A hiring process, even if you are not hiring yet. A job description template, a scoring rubric, a structured interview. Build it before you need it and you will make a better first hire.

An investor update cadence. Monthly is standard. It does not need to be long. It needs to be consistent.

The founders who move fastest are not the ones who worked hardest. They are the ones who built the right infrastructure at the right time and stopped reinventing it for every new problem.
