Hey Product Hunt! 👋
I built Syntra because I watched a friend — a carpenter in the Canary Islands — slowly go broke without realising it.
He was pricing custom tables at €400, thinking he was doing well. When I helped him calculate the real cost — wood, hardware, varnish, tool depreciation, packaging, delivery — it came to €310. He was making €90 per table working 12-hour days. And that's before tax.
The problem wasn't laziness. It was that calculating real costs requires either a spreadsheet that takes hours to maintain, or an accountant that costs more than the margin you're trying to protect.
So I built Syntra:
→ Take a photo of a supplier invoice (or forward it on WhatsApp)
→ AI extracts every material, unit price, quantity and tax rate
→ Your cost per product updates automatically
→ Your P&L is always current — no manual entry
No Excel. No accountant required. No configuration.
We're live in Spanish, Italian and English, focused on small businesses in Spain, Italy and the Canary Islands — where local tax rules (IGIC instead of VAT) make most accounting software useless out of the box.
I'd love your feedback on two things:
→ Is the onboarding clear enough to start without a tutorial?
→ What would make you trust AI to read your financial documents?
Ask me anything. 🙏

the line-item and tax extraction from a random WhatsApp photo is genuinely impressive, that's the kind of unglamorous plumbing that actually saves hours for a small business owner.

@toprak967471 Exactly the framing we care about — nobody wakes up excited about tax extraction, but it's the thing that eats an hour every week if you do it by hand. Would love to hear how it holds up on your messier invoices (multi-tax-rate ones especially) if you give it a spin.

Love that it pulls invoices straight from WhatsApp—that's where most small owners actually are. Smart call to skip the fancy portal and just meet people where they already live.

@ezgiimq3 That was the whole bet every small business owner we talked to already had photos of receipts sitting in WhatsApp, unopened. Building another portal would've just added a step nobody wanted. If you try it, curious whether the WhatsApp flow feels as natural in practice as it did in our heads.

Finally, someone who gets that a line cook shouldn't be doing data entry after midnight. Love that you built it for WhatsApp receipts specifically, that's the real channel for most small kitchens here.

@soneruludo45531 That's basically the origin story watched exactly that happen and figured the invoice was already photographed anyway, so why make someone retype it at midnight. If you're around kitchens that deal with this, would genuinely value your read on where it still falls short.
