Kayment helps Irish & European businesses get from invoice to paid. Create a professional invoice, share one link, and let your customer pay on the invoice itself—no account or attachment needed. Kayment tracks payments, can follow up when invoices are overdue, and keeps VAT records organised. Payments go through your own Stripe account. Built in Ireland.

Hi Product Hunt. I built Kayment because Irish VAT is genuinely fiddly, and every invoicing tool I tried treated it as an afterthought: one VAT rate per invoice, reverse charge as a free-text note you type yourself, and a VAT3 figure you reconstruct in a spreadsheet at the end of the period. Two things I wanted to get right. The invoice is the payment page. Your customer opens a link and pays there, by card, Apple Pay, Google Pay or SEPA. No account to create, nothing to install, no login to forget. That removes the most common reason an invoice sits unpaid. VAT lives on the line, not on the invoice. 23%, 13.5%, 9%, zero-rated and exempt can each sit on their own line; reverse charge is issued with the wording Revenue expects and reported away from your T1; credit notes are dated to the period they were issued in. The annual return is then a query rather than an archaeology project. One deliberate constraint: payments settle into your own Stripe account. Kayment is not a payment institution and never holds your money, so there is no payout schedule to wait on. It is live and taking real payments. I would genuinely like to hear where it falls short, particularly from anyone invoicing across borders, because that is the part with the most edge cases and the part I am least finished with. Thanks for taking a look.

Being able to take deposits and part-payments on the same invoice is a small detail that makes this feel built around how service businesses actually work

I really like the idea of the invoice being the payment page. It makes the whole flow much simpler.

Really straightforward to use. Being able to take a deposit and then have the rest left on the same invoice is probably the feature I use most. Customers can just open the invoice and pay from there which keeps things simple.

Also nice not having to manually check if something has been paid.

More integrations would be good. A mobile app at some point would also be handy, but the website works well on mobile anyway.

I looked at just using Stripe payment links and handling the invoices separately. This was a bit easier since the invoice and payment side are all connected.

Simple invoicing done correct. Being able to keep track of all the moving parts of customers, invoices, recurring payments, refunds all in one please in the main selling point here. I love it!

More integration would be great, quickbooks etc

Similar in terms of the overall sentiment, different in execution.
