Wave is free and already good enough for most freelancers, so the only way Ceztrix gets a first paying customer is by finding the specific person who has already bounced off Wave's clunkiness or FreshBooks' complexity and is actively looking for something cleaner right now.

What it is

Ceztrix, a deliberately simple invoicing tool for freelancers and small businesses: create a professional invoice, customise it, export the PDF, get paid, none of the accounting-platform complexity. Just launched, seeking first users.

Who actually pays

Freelance designers, developers, and consultants who invoice 1-10 clients a month, have no accountant, and want a PDF out the door in under 3 minutes without learning a new accounting system.

Do this first

Go to the Indie Hackers post 'Built a No-Friction Invoicing Tool - Would Love Feedback' (https://www.indiehackers.com/post/built-a-no-friction-invoicing-tool-would-love-feedback-7274e1d59f) and the PayNudger thread (https://www.indiehackers.com/post/chasing-overdue-invoices-is-awkward-i-built-a-small-tool-to-automate-reminders-4f89bae266), read every comment, then DM the people who said they have the problem but didn't love the solution. Tell them you built Ceztrix, offer them 3 months free in exchange for 30 minutes on a call. One paying customer from that conversation is worth more than a Product Hunt launch right now.

It takes less than you think

Three founders who were exactly here

Same space, same stage, real numbers. Every one of these is a live link you can go and read.

Early users created invoices and came back to create more

Posted the tool on Indie Hackers asking for feedback, named the exact pain point ('most invoicing tools are too bloated'), and used the community thread to find early users who shared the frustration.

Indie Hackers post

First real user from personal network, 112 community comments

Gave the tool to a family member (an electrician) who had the exact problem, got real-world feedback, and used that story to post on Indie Hackers and ask the community for advice on reaching freelancers and small businesses.

Indie Hackers post

First paying customer after one month free trial

Messaged companies where he personally knew someone, asked if they needed the tool, got on a 10-minute demo call, gave a free month, then converted to paid after adding the features they asked for.

Start here

Freelancers actively complain about invoicing complexity in these rooms right now. Three live threads found with people describing the exact problem. This is where similar tools got their first users.

Direct outreach to freelancers you already know

Start here

The Splitbee founder and the habitate.io founder both got their first paying customer from someone they already knew. This is the fastest path to a first sale and the best source of honest feedback.

PlayList 10 freelancers you know personally. Message each one: 'I built a simple invoicing tool, would you try it on your next real invoice and tell me what breaks?' One paying customer from this list is realistic.
WinAt least 3 people try it on a real invoice and one asks how to keep using it after the trial.

Indie Hackers product listing and build-in-public post

Start here

Tools in this category get discovered on Indie Hackers by other founders who are also freelancers. A genuine 'I built this because I was frustrated with X' post outperforms a launch announcement every time.

PlayList Ceztrix on Indie Hackers Products, write a post about the specific frustration that made you build it, and ask for feedback. Do not ask for signups in the first post.

Each play is the angle, not the post. You write the words: posts that read as AI get buried, and the angle was the hard part.

Not this week

Real channels, wrong for the stage you're at. Revisit once the start-here moves are landing.

Maybe laterProduct Hunt launch

Product Hunt works better once you have 3-5 real users who can leave reviews and upvote on launch day. Launching cold with zero social proof gets buried. Come back here in 6-8 weeks.

Maybe laterSEO and content

The keyword 'simple invoicing tool for freelancers' has real search volume but you are competing with FreshBooks, Wave, and NerdWallet listicles that have years of domain authority. Won't pay off for 6-12 months.

SkipPaid ads (Google or Meta)

You don't know your conversion rate yet, your landing page has no social proof, and you'd be bidding against FreshBooks and Wave with real marketing budgets. Every dollar spent now is wasted.

SkipTikTok or Instagram content

Freelancers who need an invoicing tool are not searching for one on TikTok. This channel reaches people who don't have the problem top of mind. Wrong room entirely.

Still running

Kasspian re-checked every room in this plan 7 days ago. It looks again every week.

The same plan, as text

The whole read on one page

Everything above, in one scroll: the places by name, whether each one lets you post or only comment, the drafted reply, the channels to skip, and every source behind it.

Checked

6 sources, each a page you can open and read for yourself.

Every place here was live when this ran, and gets checked again each week. A thread that has gone is marked, not left in the list.

Anything said about your own site was read off your site.

Our read, not a fact

Whether a room lets you post or only comment, on 2 of them. That is read from the rules and from what survives in the room, never from a moderator. Rooms enforce by behaviour, so open a thread in a logged out window before you count a reply as delivered. Use www.reddit.com for that check: old.reddit now shows logged out visitors a login wall instead of the thread.

Fit scores, and the call on whether a room holds buyers or people doing the same job as you. Both are judgement, not measurement.

The read

The business: Ceztrix, a deliberately simple invoicing tool for freelancers and small businesses: create a professional invoice, customise it, export the PDF, get paid, none of the accounting-platform complexity. Just launched, seeking first users..

Wave is free and already good enough for most freelancers, so the only way Ceztrix gets a first paying customer is by finding the specific person who has already bounced off Wave's clunkiness or FreshBooks' complexity and is actively looking for something cleaner right now.

Who actually pays: Freelance designers, developers, and consultants who invoice 1-10 clients a month, have no accountant, and want a PDF out the door in under 3 minutes without learning a new accounting system..

The one move this week: Go to the Indie Hackers post 'Built a No-Friction Invoicing Tool - Would Love Feedback' (https://www.indiehackers.com/post/built-a-no-friction-invoicing-tool-would-love-feedback-7274e1d59f) and the PayNudger thread (https://www.indiehackers.com/post/chasing-overdue-invoices-is-awkward-i-built-a-small-tool-to-automate-reminders-4f89bae266), read every comment, then DM the people who said they have the problem but didn't love the solution. Tell them you built Ceztrix, offer them 3 months free in exchange for 30 minutes on a call. One paying customer from that conversation is worth more than a Product Hunt launch right now.

Where your buyers are, by name

Every place below was live when the plan ran, and each one carries the reason it is here, the move to make in it, and whether that room will let you post or only comment.

  • Built a No-Friction Invoicing Tool - Would Love Feedback (a live thread). A founder posted this exact problem on Indie Hackers in July 2025 and the commenters are people who share the frustration with bloated invoicing tools. They are the buyer.

  • Chasing overdue invoices is awkward - I built a small tool to automate reminders (a live thread). This March 2026 Indie Hackers thread has 112 comments from freelancers and small business owners actively discussing invoicing pain.

Channels to start with

  • Niche community outreach (Indie Hackers, DEV Community, r/freelance) (fit 88). Freelancers actively complain about invoicing complexity in these rooms right now. Three live threads found with people describing the exact problem. This is where similar tools got their first users. First play: Reply to the 3 live threads above with a genuine comment, then DM the people who expressed the problem. Offer 3 months free for a 30-minute feedback call. No pitch, just a conversation. You will know it is working when: 2 or more people agree to a call within the first week.
  • Direct outreach to freelancers you already know (fit 82). The Splitbee founder and the habitate.io founder both got their first paying customer from someone they already knew. This is the fastest path to a first sale and the best source of honest feedback. First play: List 10 freelancers you know personally. Message each one: 'I built a simple invoicing tool, would you try it on your next real invoice and tell me what breaks?' One paying customer from this list is realistic. You will know it is working when: At least 3 people try it on a real invoice and one asks how to keep using it after the trial.
  • Indie Hackers product listing and build-in-public post (fit 75). Tools in this category get discovered on Indie Hackers by other founders who are also freelancers. A genuine 'I built this because I was frustrated with X' post outperforms a launch announcement every time. First play: List Ceztrix on Indie Hackers Products, write a post about the specific frustration that made you build it, and ask for feedback. Do not ask for signups in the first post. You will know it is working when: 5 or more people comment with their own invoicing frustration, or someone DMs asking for access.

Channels for later

  • Product Hunt launch. Product Hunt works better once you have 3-5 real users who can leave reviews and upvote on launch day. Launching cold with zero social proof gets buried. Come back here in 6-8 weeks.
  • SEO and content. The keyword 'simple invoicing tool for freelancers' has real search volume but you are competing with FreshBooks, Wave, and NerdWallet listicles that have years of domain authority. Won't pay off for 6-12 months.

Channels to skip, and why

The plan is as specific about what to ignore as about what to do.

  • Paid ads (Google or Meta). You don't know your conversion rate yet, your landing page has no social proof, and you'd be bidding against FreshBooks and Wave with real marketing budgets. Every dollar spent now is wasted.
  • TikTok or Instagram content. Freelancers who need an invoicing tool are not searching for one on TikTok. This channel reaches people who don't have the problem top of mind. Wrong room entirely.
