For multichannel sellers on Etsy, eBay, Shopify & TikTok Shop
Syncs stock quantities across your channels. That’s it. That’s the product.
No forced shipping labels. No warehouse module. No $200/mo “commerce operations platform.” SKU Sync keeps quantities matched across Etsy, eBay, Shopify and TikTok Shop so you stop overselling — and stops there.
Sound familiar?
“Every single option is universally hated.”— r/ecommerce, on multichannel sync tools

“With every solution you’re paying for functionality we don’t need.”— r/ecommerce
Sixteen distinct sellers asked for exactly this between 2018 and 2026: quantity sync by SKU, nothing else, at an indie price. Every incumbent answered with a suite.
What SKU Sync does
Quantity sync by SKU
A sale on any channel updates stock on all the others, matched by SKU. Variations included.
Official APIs only
Etsy, eBay, Shopify and TikTok Shop via their official APIs — no browser extensions, no scraping, no ToS roulette.
Oversell alerts + conflict queue
Near-simultaneous sales get flagged instead of silently double-sold; you resolve conflicts from one queue.
No bundled anything
Ship however you already ship. List however you already list. SKU Sync touches quantities and nothing else.
Full audit log
Every quantity change, its source and its timestamp — so you can trust it, then stop thinking about it.
Honest pricing, decided up front
Waitlist members can reserve founder pricing: $19/mo — locked in for as long as you stay subscribed. That's $10/mo off, forever, for backing this before it exists.
No card required to reserve. No per-seat surprises later. If SKU Sync doesn't launch, you've spent nothing and you'll get a straight answer about why.
You're on the list. One more thing —
Want to reserve founder pricing ($19/mo instead of $29/mo, locked for life)? It costs nothing now and just tells me you'd genuinely pay — which decides what gets built first.
You're in. Thank you.
I'll only email you with real progress or a launch date. If you have opinions about what SKU Sync must get right, reply to the confirmation — I read everything.
Who's building this?
I'm Aaron — a solo developer. I found thread after thread of people describing this exact problem, and I'd rather prove demand honestly (this page) than build in a vacuum. Toolshed Software's whole model: small tools, flat prices, no per-seat games, no venture pressure to raise prices on you later.
Fair questions
- Is this a real product?
- It's in active development. This waitlist decides what ships first — enough interest and SKU Sync gets finished and launched; not enough and I'll email you an honest "it's not happening" instead of pretending. Your signup is the vote.
- What will it cost at launch?
- $29 per month, flat — the price is on this page because hiding pricing until launch is how you end up with HoneyBook math. Founder reservations keep $19/mo for life.
- What happens to my email?
- It sits in a database with a timestamp and where you came from. You'll get at most a handful of progress emails and one launch email. No sharing, no selling, one-click unsubscribe.
