... When a program retries on its own, a lost response looks exactly like a failed call. For free APIs that is harmless. For anything that charges per call, a retry after a timeout can mean paying twice for one result. Building paid tools for AI agents, I ended up relying on the payment itself being single-use, plus an idempotency key that returns the stored answer for a while. The part I'm still unsure about is how long that ... ... window should be. Too short and a slow recovery gets no answer; too long and you keep a lot of state around. If your product charges

... Android app, ChargeCheck , and I'd love to hear your feedback. I wanted a simple way to compare chargers and USB-C cables without buying additional measuring equipment. Here's what the app does: Run a 60-second charging test View estimated battery-side charging

... default email tone was too friendly. Test users said they would ignore such an email. When I re-wrote the third reminder to be concise yet polite, the response time from real clients decreased dramatically. The third mistake was charging on an invoice basis. This was because freelancers have fluctuating months, and a sudden increase in charges

... upgrade. My first paid conversion happened when I completely removed the free tier and forced myself to sell the value directly in 1-on-1 calls. Did you start with a free plan that eventually converted, or did you charge from day one? Comment from Peter Jenkins(@peter_jenkins1): Hi there, Deborah! I charged

... When I started building, I had principles. I was going to stay small. I was going to keep it simple. I was going to charge what it was worth and not chase growth. I was going to be different from all those "growth hacking" startups I hated. Fast forward two years. I've added features I said I'd never add. I've done marketing I said I'd never do. I've charged

... across 700 public projects, 1.5k+ indie hackers, and a mountain of company data to answer three questions I keep arguing about with other founders: What are indie hackers actually shipping? What stack are they running? How are they charging for it? The patterns turned out sharper than I expected. Here's the honest read. AI didn't win. It lapped the field. "AI is popular" is not news. What surprised me was the margin . AI is the single most ... ... nice-to-have. Product Design is the number one skill, and Figma outranks Python.

... cost me, not by what I wanted people to do. An edit is cheap compute and expensive behaviour, and the meter should have said that from day one. If you sell credits, what have you decided not to charge for? Comment from Gal Dayan(@galdayan): retries after our own system clearly messed up, not the user. if the output errors out, times out, or is obviously broken on our end, charging

... still burned the compute. Refund it and people retry until they like the result. Don't refund and credits feel like a slot machine. We refund and eat it, which won't scale. Curious where others have landed on charging for output the user rejects. Comment from Gal Dayan(@galdayan): @asadmalik901  charging

... minor units your own record is stored in and you get 108200, which is fifty short of the 108250 on the invoice. Compare the two and the payment is refused. The invoice stays unpaid. The buyer has been charged. Nothing is broken. Every number is correct. The comparison is simply being made in different units from the charge

... When your AI does the work, you can't charge per seat anymore but the fashionable fix, charging

... When launching a product, offering a free plan feels like the obvious choice. More users, more feedback, lower friction. But at the same time, charging from day one gives you a completely different signal. People who pay often use the product differently, give different feedback, and help you understand what they truly value. The challenge is that both approaches seem to make sense. A free plan can help you grow faster. Charging

... When we set up credits, one credit meant one generation. Easy to explain, and wrong. A generation isn't one thing. The same request routed to a cheap model versus an expensive one can differ by an order of magnitude in what it actually costs us, and a retry after a bad output costs full price again. So a flat credit means the people doing simple work subsidise the heavy users, and the users you most want, the ones pushing ... ... showing that in the UI before someone commits. People are fine paying four credits for the better model. They're not fine finding out afterwards. The part I still haven't solved is retries. If our output is wrong, charging

... built idemkit after cleaning up duplicate charges one too many times. The version everyone writes checks whether a key has been seen and replays the stored response. Two requests a millisecond apart both find nothing and both charge

... Shoham(@omri_ben_shoham1): the reconciliation point is the real answer and it matches what i've seen elsewhere too. the part that still bugs me is the lag - if you reconcile nightly, you find out you double charged someone up to 24h after it happened, which is fine for catching the bug but not great for the customer who already saw two charges

... Nobody generates once. In a creative tool the real unit is six attempts and one keeper, so credit pricing quietly charges people six times for the thing they actually wanted. The arithmetic can match per output pricing exactly and it still feels worse, because every failed try has a visible price tag on it. The version that hurts most is the near miss. An output that's obviously broken costs a credit and two seconds. An output that looks right ...

... than which gateway has the lowest model price? Suppose you request model A through provider 1. Provider 1 times out, the gateway falls back to provider 2, and the response succeeds. What evidence would make you trust the final charge? Our current answer is a request receipt that separates: requested model; preferred route; final serving source; retry/fallback path; billable usage; final user charge

... Claude Code refactor our checkout flow to add an annual billing option alongside monthly. It worked in every test I ran, annual customers got charged correctly, monthly customers got charged

... European founder and I catch myself pricing lower just because I'm not in San Francisco. Same product, same value, but somehow it feels "wrong" to charge US prices. Anyone else deal with this ...

... Product Hunt! We ve all been there: you look at your bank account and see a charge, but you can't tell if it s a subscription you forgot about or just a grocery run. Tracking bills shouldn't be that annoying! So, we built Recurring Charge

... Hunters I'm Taylor, based in Alberta, Canada. I built RightsRadar because I kept watching the same scene play out: someone charged with an offence, sitting across a kitchen table from a stack of police disclosure they were never going to read and lawyers charging

... built my own tool. For context: I was running cold email campaigns across 4 mailboxes. Every warmup service I tried charged $29/mailbox/month. That's $116/mo before sending a single email. So I spent 2 weeks building WarmInbox. It does the same thing the big tools do: Connects to any mailbox via SMTP/IMAP Sends realistic emails to a pool of real accounts daily Opens them, replies 40% of the time Score goes from 0 100 over ~4 weeks Starter plan: $29/mo ... ... mailboxes (vs
