October 5–12: ¥512,670 from a month of brand resale, ¥23,291 left from ¥153,920 of plants, and $7,591 from an app that runs offline
Nine first-person side-hustle reports posted October 5–12, 2026, ranked by barrier to entry and reported payout, from a ¥512,670 month of brand resale and ¥147,051 of export bundles to ¥23,291 left from ¥153,920 of plant sales and an open-source robot with no price on it.
Nine first-person side-hustle reports were posted between October 5 and October 12, 2026, and this issue ranks all nine by how hard they are to start and by the money they reported. One line ran through the week. The largest totals came from people selling again to customers who had already bought: an eBay exporter shipped 17 of his 37 September items as combined orders to repeat buyers 1, and a brand-goods reseller took ¥512,670 in a month from fixed-price listings on four marketplaces 2. The freshest starts came out thinner, and one of them sold ¥153,920 of plants to keep ¥23,291 3.
The week at a glance
- Low — a reader could begin this week with a phone, a free account, or spare time.

Low barrier — start this week
1. Review-and-loyalty placards sold to shop counters (U.S.)
A college student sells a plastic placard that sits on a shop counter. A customer taps it with a phone, or scans the code on it, and lands on the shop's Google review page; the same tap logs a digital punch card, the buy-nine-get-one-free kind, so the shop's regulars come back. Shops pay for it monthly, and he quotes the price as $29 and up, an average of about $39 4.
Startup cash: not disclosed, and no takings are disclosed either. The $14,000-a-year figure in his post comes from his own arithmetic — one placard sold a day, every day, at about $39 a month — and it counts no customers leaving.
How he started: he designed the placard and sold it door to door, and he says the conversations are easy because shops already know why reviews matter. Read the rest of the post with care: he is now recruiting friends to sell on commission, so the monthly price list is what he charges, and the post doubles as a pitch.
2. Freelance web writing, six or seven articles (Japan)
A father of three who writes entertainment articles in his evenings reported ¥20,000–30,000 a month across six or seven pieces 5. The pace is the part worth copying: each article is finished over about three days in pieces of one or two hours, fitted around a full-time job and childcare.
That works out at roughly ¥3,000–5,000 an article. He does not claim to track his total hours, and says so: "today I got a bit further" is how the work accumulates, so the days an article takes are what he can state, while his total hours stay unmeasured.
Startup cash: not disclosed; the job runs on a laptop and an account on a client platform. His post cites the labour-policy institute's 2024 survey of 11,358 side-jobbers, in which more than 40% of respondents earned under ¥50,000 a month across all the work they ran.
Medium barrier — stock, a kit, or a routine
3. Variegated houseplants sold online (Japan)
An aroid specialist sells variegated houseplants online and has published three monthly profit-and-loss reports; the three months together are the clearest lesson in this issue. In January 2026: sales ¥91,890, profit ¥28,756. In February the sales rose to ¥140,990 and the profit fell to ¥5,365. In March: sales of ¥153,920, purchases and materials of ¥107,341, shipping and selling fees of ¥23,288, total costs of ¥130,629, and a final profit of ¥23,291, a margin of 15.1% 3.
Startup cash: not disclosed. The stock bill is the real barrier, and it grows with the sales: March alone needed more than ¥100,000 of plants and materials to support ¥153,920 of orders.
How he started: four years of growing the plants at home as a collector before he sold any. He also sells a paid guide to his method, which is worth weighing when you read his numbers.
4. eBay export of used goods (Japan)
A member of a Japanese eBay-export group reported a September 2026 profit of ¥147,051, his fourth month in a row above ¥100,000 and a whisker above August's ¥145,606 1. The mechanism is the one to notice: buy used goods cheaply in Japan, list them in English for buyers overseas. Repeat business carried the month — 37 items left the main account, and 17 of them shipped together with earlier purchases from customers who had bought before.
Two mistakes cost him real money. On 30 auction listings he entered a minimum sale price he had meant to leave blank, which came to about ¥26,000 in lost sales at $5.50 an item. He calculates that without it the month would have passed ¥170,000.
Startup cash: not disclosed, and he does not itemise what he spent on stock. His diary is published by a seller community that recruits members, and he is one of its operators, so treat the numbers as a member's self-report.
5. Odour removal for cars, homes and flats (U.S.)
Three months in, a solo operator in Dallas–Fort Worth removes smoke and pet odours from cars, homes and apartments. He took his lead problem to the sweaty-startup community after three attempts: door-to-door at dealerships brought signups but few repeat orders, Google Ads brought clicks but few calls, and Meta ads did no better 6.
Startup cash: not disclosed, and the post reports no revenue at all. He describes the work itself as good and the flow of jobs as inconsistent, which puts him in the same gap as the rest of this tier: the service exists, and the pipeline behind it does not yet.
Higher barrier — capital, or months of building
6. Pre-owned brand goods on four marketplaces (Japan)
A reseller who runs several small businesses published the September 2026 accounts for her pre-owned brand-goods arm: sales ¥1,222,492, purchases ¥587,572, other costs zero, and a profit of ¥512,670 at a 41.9% margin 2. She sold 16 items at fixed prices and 2 at auction, and her average fixed-price sale was ¥74,312 against an average purchase of ¥31,002.
Startup cash: not disclosed. The barrier is the stock bill: ¥587,572 of goods went in to make ¥1,222,492 of sales, and unsold stock ties that money up. What she does differently sits in the routine — the same listings run on Mercari, Rakuma, Yahoo Auctions and Yahoo! Flea at once, and she prices to the market at the higher-margin end.
7. An offline transcription app (global)
A solo iOS developer reported $7,591 in 28 days from LoroNote, an app that turns recordings into notes and separates the speakers, with $1,295 of that arriving as monthly subscriptions and 258 subscriptions active 7. The 28-day total includes one-off lifetime purchases, so the two figures measure different things.
The technical choice is the business one. He runs the speech model on the phone rather than through a cloud service, so every extra hour a customer transcribes adds no bill, which is what makes selling a lifetime licence alongside a subscription possible.
Startup cash: not disclosed; he lists development, testing and support as continuing costs. Marketing is App Store optimisation rather than ads — he tested Apple Search Ads and switched them off once they failed to pay for themselves.
8. A six-year dropship store (global)
A 26-year-old who has run an Instagram-driven sunglasses store for six years reported that it has collapsed to about $800 a month from a peak near $40,000 a year 8. He blames changes in Instagram's reach, and a well-paid part-time job that took his attention off the store.
His own verdict is that it cannot come back without a full rebuild, so he is testing the other asset he built: six years of paid advertising, funnel reading and conversion work, now offered as consulting to other store owners.
Startup cash: not disclosed. The revenue figures are self-reported, and the decline is his own account of his business.
9. A 3D-printed desktop robot (Hungary)
A software engineer spent two weeks of his August holiday building a small robot that imitates his coding agent at a miniature desk: it reads when the agent reads, types when the agent types, and celebrates when the work finishes. He modelled it in Fusion 360, printed the parts, added a microcontroller and tiny servos, and published the files as open source 9.
It has passed 600 stars on GitHub, and this week the 3D-model site Thingiverse put it on its homepage banner. Reported money: none, and the post contains no price and no product. Startup cash: not disclosed. The reward he describes is other people printing their own, which is worth reading next to the ¥512,670 one reseller made from stock she bought.
Three rules this week left behind
- The week's biggest totals came from selling again to people who had bought before. Seventeen of the exporter's 37 September items shipped as combined orders to repeat buyers; the brand reseller serves her buyers from four marketplaces at fixed prices; the app's income is 258 subscriptions; the placard charges each shop every month. Every entry here that made real money had a way to be paid by the same customer twice.
- Subtract the stock before counting the win. Plant sales of ¥153,920 left ¥23,291, and the month before left ¥5,365 on ¥140,990. The brand reseller's ¥1,222,492 of sales needed ¥587,572 of goods first. A sales line and a profit line answer different questions.
- The platform's rules and prices set your ceiling. One wrong setting on 30 eBay listings cost about ¥26,000; six years of store history lost their reach when Instagram changed; App Store ads went off once they stopped paying. Before you commit to one channel, read its fee schedule and its appeal process.
