Side business guide
The 9x12 side business
Run one card a quarter around a full-time job, or four a month if you want it to be the job. Here is where the hours actually go, and what the income looks like when you are honest about it.

The 9x12 model gets sold as a side hustle more often than it gets described as one. This page is the description.
You sell ad spots on a shared postcard, mail it to a neighborhood, and keep the difference. The question for anyone with a job is not whether that works — it does — but how many hours it takes and when those hours have to happen.
Where the hours actually go
For a first card, budget 27–46 hours over six to eight weeks — that is the sum of the rows below, not a rounder number that sounds better. The split is not what most people expect:
| Task | First card | Repeat card |
|---|---|---|
| Choosing routes and setting the mail date | 2 – 3 h | 30 min |
| Building the card layout and pricing | 3 – 5 h | 1 h |
| Selling the spots | 15 – 25 h | 8 – 12 h |
| Chasing artwork and payment | 4 – 8 h | 2 – 5 h |
| Print files, bundling, USPS paperwork | 3 – 5 h | 2 – 3 h |
Two things stand out. Selling is most of it, and chasing is second. Design — the part people worry about — is close to a rounding error.
The awkward constraint for anyone with a job is that the biggest block of hours has to happen between 9 and 5, because you are walking into businesses that close at five. Evenings and weekends cover the chasing and the production; they do not cover the selling.
Most people who make this work carve out one weekday morning, or sell in the hour before their own workday starts, in a neighborhood they drive through anyway.
What it earns
Using the same figures as everywhere else on this site — a median advertised spot of $477 across 76 live operator sites in 81 markets, and a 5,000-piece 9x12 EDDM drop costing $2,509:
| Scenario | Spots sold | Gross | Net per drop |
|---|---|---|---|
| A first card that did not fill | 6 | $2,862 | ~$350 |
| A typical card | 8 | $3,816 | ~$1,300 |
| A full card | 12 | $5,724 | ~$3,200 |
| Two full cards in a month | 24 | $11,448 | ~$6,400 |
The important line in that table is the gap between row two and row three. Four extra squares are worth $1,908, and cost nothing extra to mail. Your print run and postage were fixed the moment you chose your routes. This is why operators who treat filling the card as the whole job out-earn operators who treat printing more cards as the whole job.
A realistic first year for someone doing this on the side is one card a quarter, rising to one a month once a neighborhood has repeat advertisers — which lands somewhere between $6,000 and $20,000 depending entirely on how much selling time you can find.
What makes it viable as a side business
The costs come after the revenue. You collect from advertisers before the printer invoices you. That is unusual, and it is the single best structural feature of this business — it means the constraint is your time, not your savings.
The work is seasonal by design. A drop is a project with a date. You can run one, take two months off, and run another without losing anything except momentum.
The second card is much easier than the first. Repeat advertisers, known routes, a layout that already exists, and a printed card you can hold up. The hours per card fall by roughly half.
What makes it hard
Everything is a deadline chain. The mail date determines the print date, which determines the artwork deadline, which determines when checkout has to close, which determines when selling has to start. Miss one link and the whole drop slips a month.
Chasing eats the evenings. Not selling — chasing. Four logos that have not arrived, two invoices unpaid, one advertiser who said yes in person and has stopped replying. Almost every operator’s complaint about this business is some version of that sentence.
Payment links make it worse than it needs to be. A spot exists once, expires on a mail date, and has its price printed on the card. Pasted payment links model none of that, so you end up as the system: marking squares sold by hand, catching price mismatches, and re-selling the same eleven advertisers every cycle because a link cannot hold a card on file.
That last problem is not a website problem, which is why buying a website builder does not fix it.
The shape that actually scales down
If you want this to fit around a job rather than become one, three decisions do most of the work:
Run one neighborhood, repeatedly. A card that mails to the same 5,000 homes every eight weeks builds advertiser results, which builds renewals, which removes most of the selling hours. Chasing a new neighborhood each time keeps you permanently on the first-card hour count.
Give every advertiser attribution from day one. A distinct phone number, a QR code, or a coupon code. Advertisers who can see the card produced calls renew without a conversation. This is the highest-leverage hour you will spend.
Make the collecting automatic. If an advertiser can pay on the card’s own site the moment they say yes, and the square marks itself sold, you delete the entire category of evening work that is invoices and spreadsheets.
Is it for you?
It suits people who are comfortable walking into a business and asking for the sale, who can hold a deadline chain in their head, and who have a few hours in the working week rather than only evenings.
It suits people badly if the appeal is passive income. This is a sales business with a print deadline. It has real leverage — fixed costs, variable revenue — but no version of it runs without someone doing the selling.
If that sounds like the right trade, start with what is the 9x12 method for the mechanics and how to start a postcard marketing business for the order to do things in.

How many hours a week does one card take?
Roughly 27–46 hours spread over six to eight weeks for a first card — about four to seven hours a week — and most of it is selling. A repeat card in a neighborhood you already know is closer to 12–20, because the advertisers are already there and the routes are already chosen.
Can I do this without quitting my job?
Yes, and most operators start that way. The constraint is that selling happens during business hours — you need a few hours in the working week, not just evenings, because you are walking into businesses that close at five.
What does a first card realistically earn?
A two-thirds-full card of eight spots at the $477 median grosses $3,816 against a drop costing $2,509, so about $1,300. First cards are rarely full. The second one in the same neighborhood usually is, and that is where the model starts paying.
Is this passive income?
No. It is a sales business with a print deadline. What it does have is leverage: the cost of a drop does not change with how many spots you sell, so effort concentrated into filling a card compounds in a way that hourly work does not.
What is the hardest part?
Not selling — chasing. Artwork that has not arrived, invoices that have not been paid, and advertisers who verbally committed and then went quiet. Almost all of the evening work in this business is chasing, which is why the tooling you use to collect matters more than the tooling you use to design.
Do I need to live in the area I mail?
It helps enormously for the first card and matters much less afterwards. Several operators run cards in towns they no longer live in, selling by phone and email to businesses that already know the card exists.
