How to Legally Start a 9x12 Direct Mail Agency (Even While Working Full-Time)

A no-fluff guide to setting up your business the right way, so you can start getting paid fast


Starting a 9x12 direct mail agency is one of the most accessible businesses you can launch today. Low overhead, no inventory, clients pay upfront, and the demand for local advertising never goes away.

It also travels well. The model runs on one thing: a postal service that will deliver an unaddressed mailer to every home on a chosen route. The United States calls that EDDM. Canada calls it Neighbourhood Mail, the UK calls it Door to Door, Australia and New Zealand call it Unaddressed Mail. Different names, same business — and the same legal setup, adjusted for where you live.

But before you sign your first advertiser, you need to answer one question: Am I set up to do this legally?

The good news, it’s simpler than most people think. You don’t need to quit your job, hire a lawyer, or spend thousands to get started. This guide walks you through the exact steps to go from zero to legally operating, with a real business bank account and a professional way to collect payments.


First: You Can Start Immediately as a Sole Trader

In almost every country, you can legally offer services and collect money as an individual without registering a company first. The United States calls this a sole proprietorship. The UK, Ireland, Australia and New Zealand call it a sole trader. Germany calls it a Einzelunternehmen, France a micro-entrepreneur. The idea is identical: you are the business.

That means right now, today, you can:

  • Sign an advertiser
  • Collect their payment
  • Deliver their ad on a mailer
  • Report the income on your personal tax return

No company formation. No lawyer. No waiting.

But if you want to look professional, open a business bank account, and protect yourself as you grow, take the following steps. In most countries they take less than a week and cost very little.


Step 1: Register Your Business Name

You can trade under your own legal name anywhere. The moment you want to trade as something else — “Riverside Direct Mail” instead of “Jane Smith” — most countries want that name on record. This is also what a bank will ask for when you open a business account.

Find your country below. If yours isn’t listed, search for your national business registry plus the phrase “register a business name”.

Country What to register Where
United States DBA (“doing business as” / fictitious name) County clerk or your state’s business office
Canada Sole proprietorship / trade name Your provincial or territorial business registry
United Kingdom Register as self-employed (no separate name filing needed for sole traders) HMRC
Ireland Business Name (RBN) Companies Registration Office (CRO)
Australia ABN, then your business name Australian Business Register, then ASIC
New Zealand IRD number as a sole trader, plus an NZBN Inland Revenue and the NZBN register
Germany Gewerbeanmeldung (trade registration) Your local Gewerbeamt
France Micro-entrepreneur registration, which issues your SIRET The official one-stop portal (guichet unique)

Rules, fees and processing times change, so confirm the current details on the official government site before you file. Treat any figure you read in a blog post — including this one — as a starting point, not gospel.


Step 2: Open a Business Bank Account

Once your name is registered, open a business checking account (called a business current account in the UK, Ireland, Australia and New Zealand). Most countries now have online-first banks offering free business accounts with no monthly fee, which is ideal when you’re starting out.

Why you need this:

  • Keeps your personal and business money completely separate
  • Makes tax time straightforward
  • Looks professional when clients see your payment details

What to bring:

  • Your business name registration or trade registration document
  • Personal government-issued ID
  • Proof of address, if your bank asks for it
  • A small initial deposit, if your bank requires one

Once this is open, all client payments go here. Nothing mixes with your personal finances.


Step 3: Set Up Your Payment Collection

You need a way for businesses to pay you. Here are the three most practical options for a new 9x12 agency:

1. Stripe, the best option for online payments, and available in every country covered in this guide. Create a free account at stripe.com, connect it to your business bank account, and you can send payment links by email or text. Clients pay by card in 30 seconds. If you’re using the 9x12 Agency CRM, Stripe connects directly so clients can book and pay through your agency’s own booking page, no back and forth, no chasing invoices.

2. PayPal Business, widely trusted and easy to set up. Good for clients who prefer PayPal over card payments.

3. Bank transfer, cash or cheque, still common for local businesses, and in some markets still the default. Always issue a receipt and record it in your bookkeeping, even for cash.

Pro tip: Collect payment before the campaign goes to print. The 9x12 model works because clients pay upfront, that’s what makes it low-risk for you. Never print first and collect later.


Step 4: Consider a Limited Company (When You’re Ready)

You don’t need one to start. But once you’re running 3–5 campaigns per month and earning consistent income, it’s worth considering the incorporated version of your business:

Country What it’s called
United States LLC, filed with your state
Canada Corporation (Inc.), federally or provincially
United Kingdom & Ireland Private limited company (Ltd)
Australia Proprietary limited company (Pty Ltd)
New Zealand Limited company
Germany UG or GmbH
France SASU or SARL

Whatever it’s called where you are, it gives you the same three things:

  • Personal asset protection, if a client ever sues, your personal savings and home are generally protected
  • More tax flexibility, you often gain choices about how the business is taxed
  • Instant credibility, clients and vendors treat you differently

Costs range from modest to a few hundred, depending on the country, and most can now be filed online in a day or two.

You don’t need to wait for it to start. A registered business name, a business bank account and Stripe are enough to operate professionally from day one.


Step 5: Track Your Income and Expenses from Day One

You don’t need an accountant right away, but you do need a system. From your very first payment, track:

  • Income: every payment a client makes to you
  • Expenses: printing costs, postage, software, design tools
  • Profit: what’s left after expenses

A simple spreadsheet works. As you grow, small-business accounting tools make this easier, and most countries have a local favourite alongside the international ones.

Two things to watch wherever you operate:

  • Set money aside for tax. A rough 25–30% of profit is a common starting point, but your actual rate depends on your country and total income. Confirm it locally.
  • Watch your sales-tax threshold. Once your turnover crosses a certain line you may have to register for VAT, GST or sales tax and start charging it on every ad spot. The threshold is different in every country and it moves, so check the current figure with your tax authority before you get close.

Your First 30 Days: What to Focus On

Week Focus
Week 1 Register your business name, open a business bank account, set up Stripe
Week 2 Set up your agency platform, define your first campaign area
Week 3 Start outreach — contact 20–30 local businesses
Week 4 Close your first 6–8 advertisers, collect payments, send to print

The legal setup takes less than a week. The real work is building your advertiser list, which we cover in Lesson 3.

The Tool That Handles the Business Side For You

Once you’re legally set up, you need somewhere to run your actual agency, a place where clients can book their ad spot, pay online, choose their design, and you can manage every campaign in one screen.

That’s exactly what the 9x12 Agency CRM was built for.

  • Your own white-labeled agency website
  • Campaign creation with custom layouts and slot pricing
  • Online booking and payment collection (Stripe built-in)
  • Canva template library for client ad design
  • Client communication and booking management

It works the same way whichever country you run campaigns in, with your own currency and your own postal service. It’s everything you need to run a professional agency from day one, without stitching together 6 different tools.

Frequently Asked Questions

Does this business work outside the United States? Yes. Any country whose postal service sells unaddressed or saturation mail can support this model — that includes Canada, the UK, Ireland, Australia, New Zealand, Germany and France. The product name and the paperwork change; the business does not. We have step-by-step guides for Australia, Canada and the UK. See our guide to preparing and dropping off a mailing for how the hand-off works.

Can I start this business if I have a full-time job? Yes. Most successful agency owners started part-time. Running one campaign per month takes roughly 10–15 hours of work spread across 3–4 weeks. You can easily fit that around a full-time job.

Do I need a business licence? Registering a business name is a registration, not a licence. Most 9x12 agency owners don’t need a separate trading licence, but requirements are local — some cities, councils and municipalities require a general business licence for anyone providing services in the area. Check with your local authority.

What if a client wants a refund? Put your refund policy in writing before you collect payment. A simple one-liner works: “All payments are non-refundable once the campaign goes to print.” Include this in your client agreement or booking confirmation. The 9x12 Agency CRM includes booking confirmations automatically. Note that some countries give consumers statutory cancellation rights; those rules generally target consumer sales rather than business-to-business advertising, but it’s worth a quick check locally.

Do I need insurance? Not required to start in most places, but public or general liability insurance is worth having once you’re consistently earning. It covers you in the unlikely event a client claims your services caused them harm or loss.

Ready for the Next Step?
