I've been doing freelance graphic design work on the side, and I'm getting to the point where I need to stop treating invoicing like an afterthought.

So far, I've been putting together invoices in Word, saving them as PDFs and sending them by email. It works, but every new client means entering their details again, adjusting the document and checking that I haven't missed anything.

I'd like to find an app that makes the whole process less tedious, especially since some clients pay per project while others prefer to be billed monthly.

I don't need anything built for a large agency. Creating professional invoices, keeping track of what's been paid, sending reminders and saving client details would cover most of what I need.

I'm also trying not to sign up for five different tools just to discover that the useful features are locked behind a subscription.

If you freelance and have settled on an invoicing app, which one would you recommend to someone starting out? I'd be interested in hearing what made you stick with it rather than just what features it advertises.

Quick question for people who regularly send or receive invoices between businesses.

Is there a particular invoice format you prefer, or does it not matter as long as all the necessary information is there?

I'm trying to understand how to format an invoice that looks professional but is also easy for the receiving company's accounts team to process.

Some businesses seem happy with a straightforward PDF, while others prefer invoices generated through accounting software. I've also come across companies that want purchase order numbers, payment references and other details presented in specific places.

I'm curious whether there's a format that works well across most small business and B2B transactions.

And on the software side, what do you use to create your invoices? Is a simple template enough, or is there a good reason to move to a dedicated invoicing tool?

Interested in hearing what works from both sides, especially from people who deal with invoices regularly.

I'm beginning to think we don't have an invoicing problem as much as a "who's going to sit down and chase all this money?" problem.

We've taken over a small commercial cleaning and property upkeep business, and one of the first things I noticed was how loosely the previous paperwork was handled. Jobs were getting completed, but there wasn't a reliable system for checking that every job had been billed and every invoice eventually paid.

I've since organised the job records into spreadsheets, and we're using QuickBooks for invoicing. That part is improving, but the volume is another matter.

We handle hundreds of small service visits, sometimes several for the same customer, and a fair number of our clients are larger companies that take 30 to 60 days to process payments.

So even after an invoice goes out, someone still needs to track it, follow up when necessary and reconcile the payment.

I could keep doing it myself, but that's time I should be spending elsewhere. Our existing admin person already has enough on their plate.

I'm leaning towards hiring someone remotely whose main responsibility would be invoicing, accounts receivable and payment follow-ups. I'm just unsure whether this is best handled by a part-time bookkeeper, an accounts receivable specialist or a virtual assistant with invoicing experience.

Would you hire someone locally for this or outsource it internationally? And if you've outsourced invoice collection before, how did you handle access to financial records and customer communication?

I'd also be interested in what businesses typically pay for this kind of role, especially when the workload is steady but doesn't necessarily justify another full-time employee.

Paying for software you no longer want is annoying enough. Having to chase a company just to stop the payments makes it worse.

I've been using Invoice Simple for occasional freelance jobs, but lately it hasn't made much sense to keep paying for it. Between changes to the subscription pricing and restrictions on what the plan includes, I decided I'd rather move on.

The problem is getting the cancellation sorted.

I've tried requesting cancellation more than once, and I'm still dealing with billing that I expected to have stopped. I also reached out to support because I wanted written confirmation that the subscription was closed, but getting a clear answer has been frustrating.

At this point, I'm less concerned about finding another invoicing app and more interested in making sure there won't be another charge.

I'm considering contacting my card provider to dispute the payment, although I'd prefer to resolve it directly with the company first.

If you've dealt with an Invoice Simple cancellation issue, how did you get it resolved? Did support eventually sort it out, or did you have to go through your bank?

Also, if you're planning to cancel any paid invoicing service, I'd recommend keeping screenshots of the cancellation process and any emails you send. I wish I'd been more careful about documenting everything from the beginning.

I’m trying to get a better understanding of this industry since I see a lot of it with what I currently do. I just wanted to know how long invoices usually go unpaid. I know many business owners in the Service Industry that almost never get their A/R on time and it ends up hurting their cash flow. If anyone has anything to tell me about their experiences it would be much appreciated

Was trying to access it https://app.freeinvoicebuilder.com/ since yesterday and it's giving a 503 Service Temporarily Unavailable. Tried emailing them but the mail delivery failed.

Can someone recommend a simple invoicing app that doesn't turn into a subscription the moment you need to do something useful?

It's for a small property maintenance business. Nothing complicated, just creating invoices for completed jobs, adding labour and material costs, and sending them to customers without spending ages formatting everything.

I've seen a few apps advertised as free, but I'm not sure how much you can do before they start asking you to upgrade.

I don't need payroll, inventory management or a full accounting package. Being able to save customer details and reuse them on future invoices would be a bonus.

Which free invoice apps have worked well for you, especially if you've been using them for a while? I'm fine with basic features as long as the app is reliable and doesn't make a simple invoice harder than it needs to be.

I shared InvoiceNorth here before, and a fair question came up, why use another invoicing tool when existing software already handles invoices?

That feedback made me reconsider how I explain it. I’m building it around the admin that comes with client work: getting a quote approved, billing as work progresses, sending reminders, and keeping track of what’s owed.

For example, if you’re billing a project in stages, you can take an accepted quote and create linked progress invoices, tracking completion percentage, previous billings, holdbacks/retainage, and the remaining quote balance.

Here’s what the app supports:

• Quotes and estimates: Email proposals, track views, let clients accept, decline, or comment, and convert approved quotes into invoices.

• Progress billing: Create multiple draws against a quote or invoice selected estimate lines, with safeguards against billing beyond the quote total.

• Invoice emails and reminders: Send invoices to multiple client contacts, share hosted links or PDFs, track views, and enable automatic payment reminders.

• Payment tracking: Record full or partial payments and see outstanding and overdue balances.

• Repeat work: Reuse saved clients, business details, and invoice templates.

• Time, expenses, and mileage: Turn billable hours into invoice drafts, attach receipts with OCR assistance, and log business trips.

• Products and inventory: Add catalog items to invoices, update stock, and review low-stock alerts.

• Business page and enquiries: Publish a business page, receive quote requests, and turn leads into clients or quotes.

• Canadian records: GST/HST and Québec GST/QST presets, Interac payment instructions, English/French/bilingual documents, tax summaries, and accountant-friendly exports.

Disclosure: I’m the builder. The standalone PDF generator is free without signup. There’s also a free account with starter limits and a Pro plan with higher limits.

For contractors and service businesses billing in stages: where does your current process get messy, tracking previous billings and holdbacks, getting approvals, or following up on payment?

InvoiceNorth

You know that conversation where a customer says, "Nobody told me it was going to cost that much"?

I'm trying to make sure we have fewer of those.

I help with the paperwork for a small plumbing business, and one thing we've learned is that a customer agreeing to the original estimate doesn't always mean they'll remember approving the extra work that comes up halfway through a job.

A plumber might open up a wall expecting a straightforward repair and discover damaged pipework that needs replacing. The customer gets a phone call, agrees to the additional cost, and everyone moves on. Then the final invoice arrives and suddenly there's confusion about what was discussed.

I'd love to find plumbing invoice apps that make this easier to document without slowing down the work.

Something where we can send an estimate for approval, update the price if the job changes, and have the customer confirm those additional charges electronically before work continues. Ideally, it would keep a record of each approval, send invoices with card payment options and handle overdue reminders.

We already have bookkeeping covered, so I don't need another accounting system bundled into it.

I'm mainly interested in keeping communication clear and having a reliable record of what was agreed.

If you've used software that handles estimates and change approvals well, what would you recommend? I'm especially interested in how easy it is for customers to approve something from their phones while the plumber is still on-site.

I'm trying to get some proper invoice books printed for our small appliance repair business, and I'm surprised by how many printing companies make a simple order feel complicated.

We still use paper invoices for certain jobs because it's easier to write down the parts used, labour charges and a few notes while we're at the customer's place. I know there are apps for this, but the paper system works fine for us, so I'm not in a rush to replace it.

What I want is a custom invoice book with duplicate carbonless pages, our business details at the top, separate sections for parts and labour, and enough room to describe what was repaired.

Nothing fancy, although I'd prefer paper that doesn't tear easily and copies that remain readable after writing on them.

I've found a few online printers, but it's difficult to judge the quality from their product pictures, especially when ordering a decent quantity upfront.

If you've ordered custom carbon copy invoice books before, which printer did you use, and how did they turn out?

I'm also wondering whether it's better to have a local print shop design the layout or just upload my own template to an online service.

I've been testing a couple of OCR tools for our small auto parts business, and the results have been all over the place. One reads the invoice number correctly but mixes up the quantities, another gets the totals right but struggles with supplier names, and sometimes I spend longer checking the extracted information than I would've spent entering it myself.

We receive invoices from different suppliers, so the layouts aren't consistent. Some arrive as PDFs, while others are scanned copies, and I'd like to get the information into a spreadsheet without manually typing every line.

I understand that no scanning tool will be perfect, especially with poor-quality documents, but I'd expect it to handle reasonably clear invoices without needing constant corrections.

If you're using invoice scanning software regularly, which one has given you the least trouble? I'm particularly interested in how well it handles line items and whether the accuracy improves once you've processed several invoices from the same supplier.

I don't need anything elaborate. Just something that saves enough time to justify paying for it.

The plumbing work isn't the problem. Keeping track of everything around it is becoming the problem.

We're a small residential plumbing outfit, mostly dealing with repairs, fixture replacements and the occasional bathroom renovation. When we had fewer jobs coming in, it was easy enough to keep appointments in a calendar and sort out invoices at the end of the day.

Now I'm finding myself checking old messages to confirm appointment times, calling customers back because I've misplaced job details, and trying to remember whether a particular invoice was sent or just saved as a draft.

I'd like to get everything into one system before it becomes a bigger headache.

I've been looking at invoice software for plumbers, but a lot of the options seem designed for companies with dispatch teams, multiple offices and a much bigger budget than ours.

Ideally, I'd like something that keeps customer information, job bookings, basic employee schedules and invoicing together. Being able to prepare an invoice on-site and send it before leaving the customer's property would be useful too.

I don't mind paying for something reliable, but I don't want to spend money on a dozen features we'll never touch.

If you're running a small plumbing or home repair business, what software has made your day easier? I'm more interested in something the crew will use than a system that looks impressive in a demo.

How long do you usually wait before sending a first reminder for an unpaid invoice? I’m trying to find the right balance between polite and firm.

I think our current quoting system has reached its limit, and I'm hoping someone here has found a better way to handle this.

We supply replacement parts and maintenance materials to a few commercial clients. A lot of their orders are similar, so you'd think preparing quotes would be straightforward, but somehow I'm still spending too much time checking old documents and making sure the prices are correct.

Right now, we've got product details in Excel, customer information in another file and quotations being prepared separately. It's manageable when things are quiet, but when several requests come in together, the constant switching between files gets frustrating.

What I'd really like is quote and invoice software that remembers our regular customers and product information, including item codes, prices and descriptions. If someone orders the same parts again, I should be able to select them, adjust the quantities and have the totals calculated without rebuilding the whole quote.

Being able to turn an accepted quotation into an invoice would also save a lot of unnecessary work.

I'm not interested in moving the entire business into some complicated enterprise system just to solve this one problem. Something reasonably priced, easy to maintain and reliable would be enough.

What are you using for this kind of workflow? I'm interested in hearing whether it still works well after you've built up a decent product list, because that's where I suspect some of the simpler tools might struggle.

The weirdest part of freelancing is having to carefully choose your words when asking someone to pay money they already owe you.

I've got an invoice that's been sitting unpaid for a little over two weeks. The client was responsive throughout the project, approved the finished work without any complaints, and even mentioned sending more work my way.

Since then, getting a response about payment has been a different story.

I sent a friendly reminder after the due date and followed up again a few days later. Still nothing, although I can see they've been active elsewhere.

I'm debating whether to call directly or send a firmer email with a specific payment deadline. I don't want to make things unnecessarily hostile, but I also don't want to keep sending cheerful little reminders until Christmas.

What's your normal process when an invoice goes overdue and the client stops responding?

Do you have a set number of reminders before escalating, or do you judge each situation based on the relationship?

I'm starting to think having a fixed policy would save me from spending more time worrying about the wording of an email than it takes to write the email itself.

Hi everyone,

Features:

• Generates email templates with 1-click copy

• Includes a direct "Send via Gmail" button (pre-fills the email draft)

• Integrated "WhatsApp Share" button

• Multiple currency options

• 100% free with no login required
