A lot of the complexity of invoicing isn't in the PDF generation (which this tool does a wonderful job of doing, nice work!) but on the side of tracking which invoices are open vs. paid, which ones are aging, whether there are discounts that can be applied for early payment, and of course integration with whatever accounting tools you're using.

But this looks like a great, simple tool for people who need to occasionally send an invoice or two. Thanks for sharing it.

A quick and dirty invoice generator is great for people who usually do point of sale or cash transactions and once in a while need to produce an invoice so a business can pay (vs it being expensed).
Re:Show HN: Invoice Dragon – An Open Source App to Create PD... by 2Gkashmiri on Tuesday July 25, 2023 @10:54AM (#36863184)
i never understood the difference between a "bill" and an "expense". my confusion in understanding comes from the idea that a small retail trader for example, pays for 2-3 things.

either capital goods, or purchases of trading goods or expenses. Now, all of these are technically purchases". Just that your accounting ledger defines the further classification. Now, all of these require "invoice", at least in india, that means you can't just say "i paid inr 500 for fuel" without a receipt/invoice. So what is a bill and how is it different than being expensed?

Re:Show HN: Invoice Dragon – An Open Source App to Create PD... by esquivalience on Tuesday July 25, 2023 @01:49PM (#36866428)
The difference is that a bill is saying "I've done this work for you: now pay me". Or "I've given you these products: now pay me".

But an expense claim is saying "When I was doing what you asked me to do, I had to pay some money on your behalf, so please refund me".

Re:Show HN: Invoice Dragon – An Open Source App to Create PD... by bombcar on Tuesday July 25, 2023 @03:16PM (#36867879)
It’s a case of before or after the payment occurs - some businesses want it all handled via invoice so they can check things first.

Usually it’s just internal processes - Uber can be expensed, gas cannot.

Re:Show HN: Invoice Dragon – An Open Source App to Create PD... by doctor_eval on Tuesday July 25, 2023 @05:23PM (#36869815)
A bill is an invoice you send to someone else, to request payment.

An expense is an invoice someone sends to you for payment. This “invoice” might be as simple as a docket from a cash register.

If you receive an invoice from someone, it can be classified as an expense if it’s legitimately part of your business - depending on local law. If it is an expense then it’s deducted from your income so that you don’t get taxed on it - you should only be taxed on profit, not revenue.

If it’s not a legitimate business expense then you can’t deduct it from your income and the tax you pay is higher.

Re:Show HN: Invoice Dragon – An Open Source App to Create PD... by meekaaku on Thursday July 27, 2023 @03:52AM (#36890333)
A bill or an invoice is a document created by the vendor asking the customer to pay. Sometimes you are the vendor and raise an invoice asking the customer to pay. Other times you are the customer, and your vendors send you invoice asking YOU to pay.

It is generally accepted practice in accounting that all outgoing payments should have an invoice from a vendor. Also all incoming payments should have an invoice/receipt raised by you.

Whether something is an expense depends on what you are paying for. If the vendor's invoice is for goods that you are reselling, that is not an expense. That goes to inventory. Similarly when you pay an invoice from your heavy equipment supplier, that is not an expense, that goes to your equipment & machinery. However, when your vendor invoice is for something like janitorial service, utility bills, lawyer fees etc, these are classified as expenses and hence its 'expensed'.

Also in some (most?) countries, regulations impose a strict versioning of invoices and a strict irrevocability process (meaning you cannot edit an invoice after its been delivered). To be compliant with the laws, as a company you need to prove you are using a system which is compliant with theses constraints.

For instance in France, it has been mandatory to use such compliant software since 2018 for all companies.

I would assume this would be for cases where your are using that same software to report income, expenses, tax etc. But in this case you would be keeping a copy of the invoice for later reference in calculations, the same as a handwritten invoice, no? It's just "typing it up" for you.

Not really. Well, only if you are a really really small company (read below VAT threshold).

Once you're VAT registered the tax authorities will want the irrevocability.

Re:Show HN: Invoice Dragon – An Open Source App to Create PD... by Roark66 on Tuesday July 25, 2023 @06:31PM (#36870593)
There is no such thing as irrevocability in IT(unless we talk about physical retail sale registers every retail business has to have - these are certified standalone hardware devices that print receipts and store the transaction details in write once memory). At least in this EU country the requirement is that you keep the original file for the retention period and you present it on request. If you mess with it in the meantime and you get caught you're essentially falsifying financial tax records. It doesn't matter if you keep your invoices in .txt files on a hard drive or in a cloud based "irrevocable" system But if you're doing retail your accounting data better matches with the printout from that hardware device that logs all the sales.

However, having said that the complexity in doing small business accounting (at least here in Poland) is not in generating invoices, but in accounting for them correctly with regards to VAT. Is this just a domestic sale/purchase? Is it an EU goods or services purchase/sale? Is it the same but for outside EU? Is the client a company or an individual? Does he/she want to return a item. Did you send an invoice, but never got paid? (you're still on the hook for the VAT) All those things matter and affect how you're supposed to record your VAT. In many cases of cross border transactions you end up recording VAT in a special way so it cancels out, but you need to report the right amounts. The logic to not mess this up is what makes people pay for this software. There is nothing stopping you doing all of it in Excel if you want, but if you mess up... It might be expensive.

At least in NL, the final version becomes irrevocable when it is send to the customer (or supplier). Corrections are done with a new number (or more than one) Sometimes you need more than one sequence.

In Sweden, this applies to the accounting system - bookings need to be immutable but there is no certification of the software. The invoice generation is not covered, they need to state due date, VAT number etc, and the invoices need to be booked in the accounting system but can be typed on a typewriter, or written by hand even, as far as I know.

This would be a fantastic way to give your customers a bear-hug and slowly pull them into a full ERP system.

I have personally seen myself and other business owners issue invoices that are unconnected to any system early on - just generating it using some ill-suited tool like Word.

But once your customer enter their invoice data in Invoice Dragon, it's a simple matter for you to set up a "payment due" reminder for them. And then add on outstanding balance per customer. And so on, and the next thing you know, it's an ERP!

Re:Show HN: Invoice Dragon – An Open Source App to Create PD... by bokstavkjeks on Tuesday July 25, 2023 @10:10AM (#36862502)
While true, it's often two distinct processes. I work with implementing ERP systems, focusing on accounting and financials. Most systems I see use the ERP system to generate the invoice data and for tracking the invoice status with a separate service to create the PDF (and electronic) invoices through an integration with the ERP system. The ERP system is usually pretty good at invoice tracking but customising the invoices can be both time consuming and expensive. Among larger enterprises there's definitely a market for software that can produce PDF invoices, even without tracking, although they would probably have to support creating PEPPOL BIS compliant XML documents as well.
Re:Show HN: Invoice Dragon – An Open Source App to Create PD... by conductr on Tuesday July 25, 2023 @11:28AM (#36863742)
I could be wrong, but if the business is using ERPs (to the extent of hiring implementation specialists), they're likely already too big for this type of software. In it's current form anyways, this feels like something small business uses to appear professional, big and/or well polished. The bigger company would use the ERP solution because it integrates with their general ledger, etc. and at that scale putting any focus on 'pretty invoices' is probably just a waste of time. It's really better to focus on getting them paid quickly.

We see this pattern a lot.

It's like twitter. You can write an app that works just like twitter in a short amount of time. A week tops. But that's not the hard part. Moderation, getting the product profitable, etc, are the hard parts.

People often get a bit of tunnel vision and don't realize there's a whole bunch of behind the scenes stuff that's the real hard part. No reason to feel bad about it, it's a human thing, not just (the proverbial) you.

It's not like Twitter was beloved before, and neither are people actually leaving the platform (except for the dozens who care a lot).

Like most content on Twitter, the discussion around it is mostly a loud minority complaining.

Re:Show HN: Invoice Dragon – An Open Source App to Create PD... by wsatb on Tuesday July 25, 2023 @03:32PM (#36868101)
Are people actually not leaving? I had not used Twitter in about a year and a half until last week. I went there and it took 20 seconds to load the web app, then after I logged in it was Elon getting promoted, ads that look like mostly spam, and everyone with a blue check mark. I left because I thought the platform was deteriorating then and it is much, much worse now.
Re:Show HN: Invoice Dragon – An Open Source App to Create PD... by blauditore on Tuesday July 25, 2023 @03:52PM (#36868374)
The question is always: What's the alternative? People who are either addicted to what they get from Twitter, or whose job depends on it, have no other place to go. Of course there are other platforms, but those only have a tiny fraction of the user base, meaning less content and less attention.
Re:Show HN: Invoice Dragon – An Open Source App to Create PD... by soneca on Tuesday July 25, 2023 @04:35PM (#36869009)
I would guess that people who are addicted to it or whose job depends on it are not the majority of Twitter users.

I agree that even out of those groups, there are not a lot of people deleting accounts and moving to other places. But, my perception is that a lot of people are indeed spending much less time on Twitter. Twitter competitors are not only Mastodon or Threads. It is also YouTube, TikTok, Instagram, Netflix and alikes, advocacy for consuming less social media overall, etc.

It was my favourite social network, and I had multiple accounts. I used it slightly professionally, but wouldn't say my job depended on it. Months ago, I deleted as many tweets as I could without paying to deal with more, and stopped using it. I don't feel like I've missed it all that much. The engagement when active never felt that great, so that probably helped. I've never used Facebook either.

I do feel a bit like "what's the alternative"; I like being an active contributor rather than a passive consumer, so falling back to just reading scraps on the net makes me uneasy.

> Are people actually not leaving?

It can be hard to tell, the published numbers and other people's guesstimates do not tell much of the full tale.

I think many are soft-leaving: using twitter and which-ever alternative they are considering in unison while they see how things play out. Perhaps more than one alternative. People will eventually decide because multiple contact points will be a hassle, at which point we might see a glut of people leaving twitter if one of the alternatives has enough momentum at the time.

A significant problem ex-twitter has is that much of the advertising that left has not returned while user and bot activity hasn't dropped by nearly enough to compensate for that so the on-going losses have grown despite all the staff cuts and so forth. Some advertisers are splitting their spend elsewhere, some are playing wait-and-see like users, and some have just realised that dropping (or reducing) twitter as a channel hasn't harmed their RoI on marketing budget so maybe it wasn't a great channel for them in the first place.

[caveat: I've never actually used Twitter, other than being sent links to threads occasionally and thinking “this is a terrible way to get across an idea worthy of more than one sentence”, so might know nothing – long before the recent kerfuffle I considered it “too full of the sort of people who consider twitter to be a good idea” and from what I gather indirectly it is increasingly home to a lot of the sort of people/content that I already get irritated enough by on other channels!]

People have left. A ton of the technical people I follow have moved mostly to mastodon. Dan Luu of HN fame regularly posts on mastodon but hasn’t cross posted on twitter as often (which is sorta funny because he used to work for twitter, and left before the Musk acquisition.) Some people are still “on” twitter but post much less than they do on mastodon, like Daniel Stenberg (you might know him as the maintainer of curl.)

To be honest, as someone who doesn’t care about the twitter culture war and still sees a lot of value in the site, mastodon is steadily becoming a better place for actual technical content. Twitter blue checks have insufferable opinions, and I did better when their existence wasn’t forced on me.

In my experience

- you either did work for someone who does pay invoices, or doesn't

- if you are boned when the last invoice isn't paid, you are in very deep trouble. That means you're not in the "invoicing" business, you're in the flipping business

- so optimizing for the best case, well, you don't need to really track this stuff, or offer discounts for early payment or whatever

> of course integration with whatever accounting tools you're using.

Of course, you could be charging enough money that you don't really have to think about your costs.

The kind of person doing that has the bandwidth to install and use open source tools.

So ironically, the person who is arguably the best B2B customer, making tons of money, lots of bandwidth, pretty sophisticated, is the person most likely to use a simple open source invoice PDF generating tool. And that's why these things get adoption. That's why open source thrives.

I don't know if Invoice Dragon will make money but its users are necessarily going to be great. Because the person who gets the most out of it is running a great business.

That doesn't make any sense to me. If you have a thriving profitable business you usually just pay for invoicing software. Why would you invest time fiddling around with an OSS tool? just because you have the bandwidth doesn't mean you'll use it on that. Most people will prefer spending the time on something else that is core to their business or just their personal lives.

Open source thrives for many reasons. I hardly see what you described as one of them.

You are correct. I'm in the process of trying to find software to manage the collection of 1000s of fines. It's a very niche area. It's not even the payment part, as we have that part completed, it's the tracking and "attempting" at contacting people which may or may not want to be found!

What you’re describing is accounts receivable. As you say, it’s a separate function relative to invoice generation and payment.

It’s not an overly complex problem to solve in the general sense but it is very easy to underestimate the complexity, and this often leads to half baked systems.

When I was independent consulting, GnuCash managed my invoicing and accounts-receivable well enough.

I tracked my hours for a billing period by starting a new invoice in GnuCash, and just adding a line item to it per day. Each line item was updated throughout the day, with very quick notes to myself of what I did.

At the end of each day, I'd print a draft invoice of the unbilled hours thus far, as backup.

When it came time to invoice, GnuCash supports/ed custom invoice scripts, so I'd copied&modified a stock invoice script to do what I want, including hiding the notes to myself, and complying with the occasional format change requests from client. I'd print to PDF or paper.

For a client that also wanted a separate summary of what I did, I'd copy&paste the hidden notes into an editor, and then rewrite that as a concise one-to-few sentences.

As soon as I emailed/mailed the invoice, the GnuCash accounts-receivable functionality would take over. The complexity in how it represented the data was a little scary, but it worked.

I concur. And I have some insight into this. I wrote a command line invoicing tool[1] which I referenced on an earlier thread since I knew a bit about generating PDFs and thought that was the "hard part" of this.

The real value is in being able to respond quickly to queries like "What were the invoices numbers for client X in Jan, Feb 2022?" when your accountant asks them. Managing that, timesheets etc. in a way that can give you insight into business financials is what's really useful once you cross a (low) volume of invoices.

That being said, the output of the tool is extremely good looking.
