Built for guitar builders first — and every other instrument maker who's tired of the same broken problem. Tessero-Synq sits between your store and your dealer network, automatically pushing every product change to every authorized reseller in the format their platform needs.
The problem
No one has solved the last mile between manufacturer inventory and dealer storefronts. Until now.
Manufacturers
"You update a price. 47 dealers still have the old one."
Manual email blasts to distributors. No confirmation anyone updated. No visibility into what your network is actually showing customers.
Dealers
"Onboarding a new brand takes a full day of copy-paste."
You're re-typing spec sheets, reformatting images, rebuilding variants from scratch — for every new supplier relationship.
The industry
"There's no system. Just spreadsheets and email threads."
The guitar trade — and the broader instrument world — runs on relationships and trust. But product data still flows on PDF spec sheets attached to 2009-era emails.
How it works
Three steps. No custom integrations. No ongoing maintenance required on either side.
Step 01
Manufacturers connect their existing product store via webhook or CSV upload. Nothing changes on your end — your store stays your store.
Step 02
Grant dealers access to your full catalog, a specific brand, a product category, or individual SKUs. You control who sees what, down to the product level.
Step 03
Update a price, add a variant, change a spec — authorized dealers see it immediately, ranked by priority. One click to download a platform-ready export.
Built for both sides
Connect your store once and let Tessero-Synq handle distribution. No extra portals, no spreadsheet attachments, no follow-up phone calls.
Accept a manufacturer's invite and instantly get a complete, import-ready catalog for your platform — updated automatically whenever the brand makes changes.
Features
Built for guitar builders first — and welcomed by every other corner of the instrument trade. Not retrofitted from a generic PIM or ERP.
Grant access at the catalog, brand, category, or individual SKU level. Dealer relationships vary — permissions should too.
Price updates and discontinuations surface as HIGH. Spec changes as MEDIUM. Dealers always know what to act on first.
One catalog, four formats: Shopify, Squarespace, Amazon, and universal CSV. Ready to import without any editing.
Shopify and Squarespace push product events directly to Tessero-Synq. Your catalog stays current without manual uploads.
Not on Shopify or Squarespace? Drop in a CSV. Smart column mapping handles the translation automatically.
Dealers get a live Google Merchant Center XML feed — always formatted to spec, always reflecting the latest catalog.
Guitar builders & early partners
We've already partnered with several independent guitar builders who are quietly syncing their dealer catalogs as you read this. They asked us — very politely — not to say who yet. We respect that kind of discretion. It's a small industry and people talk.
Join early access and your brand takes one of these spots. You'll be in good company. Probably better company than you'd expect for something this new.
What people are saying
Real testimonials from real guitar builders are on their way. In the meantime, here's what the people who built this thing have to say — at least they're honest about it.
"I built Tessero-Synq because I once spent an entire afternoon re-entering the same guitar spec into three different dealer portals. It wasn't my finest afternoon. It was, however, a very productive weekend."
"We asked several of our early guitar builder partners for a quote. They said, and we quote: 'We'd rather just keep using the product.' We're choosing to take that as a strong signal. More testimonials loading — probably once they finish shipping their holiday orders."

Early access
We're onboarding a select group of manufacturers and dealers during early access. No pricing commitments — just early priority and a direct line to shape the product.
No spam. No pitch decks. Just a confirmation and next steps when your spot opens.
Tessero-Synq is built by a single developer who came from the guitar and instrument world and got tired of the same broken data problem. If it saves you time or solves a real headache, consider supporting the development directly.
