While we're on the topic of ERP: I have noticed that, in 2025, many small businesses still use Excel. Is there an underserved market? Or simply a "tarpit idea" (deceptively attractive but actually unscalable, time-consuming) I asked 5 friends who are business owners and 5 who are working for SMEs. None of them use "apps". The best they use is accounting app.

I've been thinking about something similar. I think there's a market for "local handmade software" in cases like that, where a software developer can come in and build a little system tailored to a specific problem they have.

My dad has been a solo fabricator for most of my life, and what has always struck me was the way people came to him with jobs. Sometimes they'd show up with drawings and detailed designs, but mostly they'd just ask him to come look at something (or bring a photo), and describe the problem. He doesn't know CAD, so the drawings he makes are mostly just on napkins. The customers quite literally didn't know what they were getting before they got it, but that is fine, because they don't know what they want either.

I wonder if there's an analogue to that for software. A freelance local software developer these small businesses could go to if they had a process problem they'd like to solve.

Is this a kind of developer BINGO? ;-) "Techstack Remix – framework Typescript – language Tailwind – styling Radix UI - behavior Supabase - database Supabase – auth Upstash - cache Trigger - jobs Resend – email Novu – notifications Vercel – hosting Stripe - billing" And no joke: congrats to your product!

Yeah, that's a lot of hosted solutions for an ERP.

It is both underserved and overserved.

The problem for small businesses is ownership and tailoring/complexity. Self-hosted solutions sound great but you need someone that knows how to run it.

Cloud solutions sound great and every VC-funded startup (there is plenty) would love you to buy-in, but that's a massive operational risk to a small business that would become entirely reliant on it. That's on top of every ERP having different workflows and either having to adapt to one or customize it to match your small business. Small businesses often don't exist by copying the ideas and workflow of another company as several industries can be highly competitive and the smallest of "custom steps and processes" can eek out a tiny niche.

And then there's the "big brand, never going away solutions", but they cost a fortune beyond what any small business can afford and likewise need developers just to customize it.

So, with many small business owners, who most likely are not a HN user nor have a github account and work on stuff that has nothing to do with the web. They will look at the ERP offerings, look at their spreadsheet and say "yea imma just go with excel"

I did an ERP implementation for manufacturing years ago, it was such a nightmare.

I imagine a good approach that would solve some of my reservations would be a strict core ledger, especially as it relates to inventory and finance related transactions, but then relatively flexible around the specific product domain (we did craft beer, which in the end was a nightmare to map to the ERP processes)

Flexible where it matters, strict where it matters. Idk, but good luck!

I'm in this industry and very interested in efforts like this.

What is the plan to monetize and support.

You'll never get market share without support, and that takes money. Support contracts. SLA's. Any company larger than 10 people aren't going to bother with something that doesn't provide support.

> Edit. Sorry. Had to click around a bit. 90$/Month for business. > Probably light. If business is 1000 people, this could be 1000$/month.

I have to add, I think all of the current tools that do have the market share, are not very good. So I do want something like this to succeed.

Do you have any users yet? What’s your target size manufacturing company? I’ve been in the industrial software space for a while, and at least for large MFG, you only see the major players, with SAP being the most common. There is this “UNS” concept that’s been around for 5ish years now and has caught steam (unified namespace, google and you’ll find it). It has holes from a technical standpoint, but it will get atten…

The current offerings, like SAP, GE tools, etc.. Are so over-complicated and bloated, that most of the money spent is just to figure out how to configure them.

Most people hate SAP but don't know what to do. Caught in catch-22, they hate it, but don't trust any other options.

Impressive. Some questions: - Who is 'I'? - How do you see continuity if something were to happen to you? - How does it stack up against ERPNext? - Why did you decide to build an ERP system from the ground up? - What is the deployment situation?

Good questions. I'd like to add some, if you don't mind. How does it stack up against Sage? Expanding on "what is the deployment situation," how long should it be expected to take for full conversion to the Carbon platform from the described situation of discordant software that has been entrenched in a particular business's practice for decades?

hey guys -- founder here.

here's a little bit about me, and why i decided to build this: https://carbon.ms/#memo

re: sage, i'd say that sage is well-known as being a great general purpose accounting software for multi-location, and multi-entity businesses. but i don't know of many manufacturers running on sage.

re: erpnext, also great. i love their open source model, their developer ecosystem, and great documentation. i'd say the major difference is the data model and the UI that it begets. in erpnext, i think everything is a "doctype" where with carbon things are more bespoke. each ui has it's own specific tables, and specific ui

Basically the core functionality is to track inventory, manage purchase orders in, and sales orders out. Generally that's also linked to accounting so basically as you buy and sell stuff everything is linked to your accounting ledgers. Then there's MRP (M for manufacturing) which is usually an option - for when stuff that you're selling isn't the same as what you're buying. So the ERP/MRP manages bills of materials f…

Not all materials are parts. For instance, if you run a soup factory you don't order 'soup parts' but bulk ingredients in the same proportions that you end up selling, but there are many other things that you need to worry about in the process of preparation and there are things that don't even make it into the end product at all that you still need during the manufacturing step (for instance, cleaning products, vari…

Yes. Most ERP's also handle 'ingredients'. Really, it is any 'inputs' to the product. And potentially, byproducts produced and also sold. All In's/Out's, and how to track them.

> internally transforming the company I'm not sure how things are now, but I once worked tangentially on a mid-sized corporation ERP rollout. At that time it was not unusual to have an entire department at the ERP-adopting company called "Change Management." Any company-wide process change was managed by the Change Management department.

Oh that brings memories! Been in quite a few of those. Basically the ERP vendor sells you the software and estimates that you need a couple months and a couple consultants for the migration and integration, plus a few users of your product as guinea pigs. It is expensive as heck but well, at least it is only two months (plus hotels, plane and food). After two months you’re halfway done according to the vendor but you…

I've seen this balloon to hundreds of consultants. It can break a company. You get huge sunk cost into you're continually 90% done ERP and management either doubles down to spend one year to just get it barely working and stop, or cancel it.
