Erply Integration Specialists

We make Erply work with everything else.

KnotSync isn't another SaaS app you log into and figure out on your own. We build, run, and maintain deep integrations between Erply and the tools your business depends on, and we stick around to keep them working.

SOUND FAMILIAR?

Off-the-shelf connectors handle the easy 80%. The other 20% is what breaks your books.

Generic sync tools choke on the messy stuff like refunds, transfers, multi-store, and COGS.

Your numbers don't line up between systems, so you don't fully trust any of them.

You end up re-keying data by hand anyway, the exact thing you were trying to avoid.

QUICKBOOKS ONLINE LIVE

Your Erply sales, posted to QuickBooks the way an accountant would.

Most connectors dump a lump sum into QuickBooks and call it synced. We post proper, accounting-grade entries, the kind your bookkeeper doesn't have to fix.

Full journal entries

Daily store sales posted as gross sales, COGS, sales tax, and every payment type, broken out per store.

Bills and vendor credits

Purchase invoices and vendor returns posted automatically, with terms, vendors, and accounts mapped correctly.

Written back to Erply

Posting status flows back to Erply, so you always know what's landed.

Duplicate-posting protection

Run it twice and it won't double your books.

Live and running in production today.

SQUARE LIVE

Run Square at the counter. Keep Erply as your source of truth.

Love Square's checkout hardware? Use it. KnotSync flows every Square sale straight into Erply automatically, so your inventory, sales, and reporting all stay in one place.

No manual entry

Ring sales on Square hardware and they land in Erply automatically.

Per-register attribution

Every sale matched to the right store, automatically.

Refunds done right

Cross-store refunds and returns handled correctly, the edge case generic tools get silently wrong.

Full detail carried through

Receipt numbers and payment detail preserved, not dropped.

Erply stays the system of record. Square just makes the front counter nicer.

NEED SOMETHING ELSE?

If it has an API, we can connect it to Erply.

QuickBooks and Square are what we run today, but they aren't the limit. We've built and operated real production pipelines well beyond the standard connectors, and we're always adding more.

Marketplace & fulfillment

A full pipeline pushing Erply inventory and pricing to Sellbrite and out to the online marketplaces it feeds, then pulling fulfilled orders back from ShipStation into Erply with automatic inventory transfers.

Staff scheduling

A Humanity integration for workforce scheduling.

Using a different tool? Tell us what it is. If your business depends on it, we'll figure out how to connect it.

HOW WE WORK

We're not another app. We're part of your team.

Most integration tools hand you a dashboard and wish you luck. We don't. We build your integration, run it in production, and stay on the hook when something needs attention. You get a person who knows your setup, not a support ticket queue. That's also why we take on a limited number of clients at a time: these are complex, accounting-grade integrations that touch your money and your inventory, and every one deserves real attention. If we're at capacity, we'll tell you straight and give you a realistic timeline.

WHY WE BUILT THIS

Built because we needed it to actually work.

We built KnotSync for a real retail business that was drowning in manual data entry across five platforms. A previous solution never worked reliably, so we built something from scratch that did. Now we're making it available to other Erply-based businesses who have the same problem.

Let's figure out if we can help you.

No hard sell. Tell us what you're trying to connect and we'll have an honest conversation about whether KnotSync is the right fit.
