“i know the title sounds made up. invoice reminders for plumbers. $14K a month. but that's exactly why it works. nobody is competing for this because nobody thinks it's sexy enough to build. i've been obsessively tracking how people find profitable software ideas for the past 6 months. cataloguing complaint threads, scoring problems by pain level, mapping which ones turn into real revenue. this guy's story is the clearest example of the pattern i keep seeing. here's what he did step by step. step 1. he wasn't even looking for a business idea. he was browsing a subreddit for trade contractors and saw a thread where a plumber said "i'm owed $47K in unpaid invoices because i forget to follow up." 12 other contractors replied saying the same thing. one guy said he hired a part time person just to chase payments. step 2. he searched for existing solutions. found 3 invoicing tools that technically had reminder features. all of them were $100 to $300/month, built for accountants, and requi”

“Is there field service management software that doesn't assume you have a team? I run residential HVAC solo, sometimes one helper when it gets busy. Every platform I've looked at has dispatching boards and crew scheduling and membership modules and all this stuff designed for companies with 10+ trucks. I need to send estimates, invoice customers, and get paid and that's it. Maybe answer my phone somehow since I miss half my calls during installs but that is optional, I dont think any has that built in. I don't need to dispatch anyone, I know where I'm going because it's me. What are other one person operations using day to day?”

Solo residential HVAC operators need lightweight field service management software without team dispatching or enterprise features — clear gap vs tools built for 10+ truck companies

“I do automation and software work for small businesses — trucking, cleaning, property management, plumbing, that world. I kept hearing the same complaints across totally different industries so I started logging them. Eventually I had enough raw data that organizing it manually wasn't realistic. That's where Claude came in. I used Claude Code to build the whole platform from scratch. The main things Claude helped with: * **Data pipeline** — I feed in raw problem descriptions from industry forums and client conversations. Claude classifies each one by industry, category, severity, and affected role (owner, manager, field tech, etc.) * **Opportunity clustering** — Claude identifies when multiple independent reports are describing the same underlying problem and groups them together. That's how you get the "15 reports" signal on trending problems. * **App concept generation** — for each clustered problem, Claude generates a SaaS concept with a name, feature set, and revenue model. Take”

“Hey everyone, I’m validating an idea and I’d love honest feedback from mechanics and independent shop owners. From what I’ve seen, in many small/medium repair shops: • Mechanics don’t touch the computer much • VINs are typed manually • Job status is often unclear (“Is it done?”) • Customers call to ask for updates • Follow-ups for future services are inconsistent So I’m thinking about building a small rugged handheld device (pocket-sized) that mechanics can carry in the shop. It would: • Scan VIN or license plate with a camera • Start a job with one button • Mark it as done with another button • Sync automatically to a simple shop management system The software side would handle: • Automatic job creation from VIN • Vehicle service history • Job status tracking (In progress / Done) • Automatic SMS when car is ready • Automatic service reminders (e.g., oil change in 12 months) • Basic dashboard: jobs per day, returning customers, monthly revenue The ma”

“with claude and codex, anyone can build an app now there should be a design and copy interface where you take the UI of a existing webpage or multiple pages, just drag and drop the components, colours on prompt instead of the rgb stuff, and place text and logic and all that once submit it gives the dev component that can straight be fed back to claude code in 3-5 minutes.”

Developers need an AI drag-and-drop UI/clone tool that ingests existing web pages, lets users prompt-edit components/colors/copy/logic, and outputs production-ready apps using Claude/Codex — no current product does this end-to-end

“EDIT - 2-24-2025 - Hey all, after getting so much continued feedback from this post, I've decided to make an app to help people when purchasing vehicles. I know some of the things on here, especially the OBD2 data, may be a bit daunting, so I'm hoping to put something together that gives you tips, tricks, and helps pull the OBD2 data in an easy to interpret way. If it takes off, it could even turn into something that can help budding driveway mechanics fix their vehicles. If you're interested, head over to https://carprocheck.com/waiting-list and let me know! I’m a mechanic/auto shop owner. I figured I’d put some stuff together for anyone interested in buying a used car but doesn’t know anything about cars. Obviously the best option is to take it to an auto shop to have it thoroughly inspected by a professional before you buy it. The key word here is BEFORE you buy it. I don’t know how many people I’ve had come to my shop for an inspection after they bought it….ugghh. The $150 or so”

“I run a 12 person company and I just did our annual software audit and the number genuinely startled me so I want to see if other business owners are experiencing the same thing. We are paying for 23 separate software subscriptions right now, everything from accounting to project management to CRM to email marketing to analytics to internal communication to file storage to scheduling to customer support to payroll, and the total monthly spend across all of them is $4,100 which is almost $50,000 a year on software for a 12 person company. five years ago that number was about $1,200/month for roughly the same functionality the thing that's happening is every tool is creeping their prices up 15 to 20% annually while simultaneously moving features that used to be included into higher tier plans, stuff that was in the basic plan two years ago is now "premium" and the basic plan has been hollowed out to the point where it barely does anything useful but the part that really gets me is th”

“We have a client who has been asked by their governing board to have a physical onsite copy of their data separate to the offsite backup they already have for M365 (we currently use Ninja Saas backup which is just Dropsuite white labelled). Trying to avoid them having to manually download the SharePoint data (I can also envision this being a nightmare with OneDrive syncing limitations). Ideally if there was a backup solution in place that allowed storing the data to their own infrastructure that would be ideal. I've already tried to talk them out of the need for doing this, saying that in the very unlikely event that Microsoft went down indefinitely there would be bigger issues to deal with. This is coming from above them though so I've just said I'd have a look for a solution. Thanks, ”

MSPs need M365 backup to local/on-prem storage solution — client mandate for physical copy, NinjaRMM/Dropsuite insufficient

“Hi all, I develop custom software for a few accounting offices and professionals in the Netherlands. One topic that comes up in almost every meeting: clients (ZZP'ers, small businesses) send most of their invoices, receipts, delivery notes, payslips, contracts… directly via WhatsApp, as photos or PDFs. Then someone in the office has to open each file, read it, and manually enter the key data (amount, BTW, date, supplier, description…) into accounting software, Exact, SnelStart, Excel or straight into BTW-aangifte. Even if it's "just" 15-30 documents per day per client, with multiple clients it becomes hours a week of repetitive, error-prone work. In the offices I work with, this is still everyday reality and consumes a lot of time. How is it for you? Does this happen often too? How much time does it take you per week approximately? Have you found any effective way to reduce it (some program, trick or flow that really helps)? Or are most clients now using portals/email and Wh”

“Hey everyone — I run a small vending operation and got fed up with the monthly grind of pulling CSVs from Nayax, reconciling in Excel, manually calculating location commissions, and still not knowing which machines are actually profitable. So I built something to fix it: **Vendric** (vendric.io). It's a management platform made specifically for vending operators. Not a generic business tool with vending slapped on top. **The stuff it handles:** * **CSV imports** — drag and drop your sales reports from Nayax, Cantaloupe, or whatever you use. It maps your columns automatically. * **Commission reports** — set your rules once (percentage, flat, tiered), click a button, and a PDF goes straight to your location owner's email. * **Per-machine P&L** — actual profit per machine after expenses, commissions, and VAT. Not just top-line revenue. * **Inventory & restock alerts** — know what's running low before a machine goes empty. There's a 14-day free trial, no credit card required. ”
