Rev3 Relay connects Shopify to QuickBooks Online and keeps orders flowing as invoices — automatically. If a sync ever fails, you find out within minutes, with exactly what broke and a way to fix it.
No credit card. We'll email you when early access opens.
Across the existing Shopify-to-QuickBooks connectors, the same three failure modes show up again and again — and every one of them is invisible until someone goes looking.
Orders stop syncing after a rate limit or a token hiccup. Nothing errors loudly — they just pile up until someone reconciles the books and finds a gap weeks wide.
A routine update on either side changes a field mapping or an ID format. The sync keeps "running" — it just stops actually writing anything correct.
Manual troubleshooting re-runs a sync that already partially succeeded, creating duplicate invoices that are worse to untangle than the original problem.
Three steps. No spreadsheets, no manual entry.
Authorize Shopify and QuickBooks Online once. Takes about two minutes.
Every new order becomes an invoice in QuickBooks — line items, tax, and shipping included — the moment it comes in.
No news is good news. If something can't sync, you get an alert with enough detail to fix it in one click.
We don't promise a sync that never fails — nobody honestly can. We promise you'll never be the last to know.
Every order is tracked by ID before it's sent — retries can't create duplicates.
Transient failures retry automatically. Anything that doesn't resolve reaches your inbox and dashboard the same day, not the same quarter.
Every night, we diff Shopify orders against QuickBooks invoices — amounts included — to catch anything that slipped past the first two layers.
We're onboarding a small group of Shopify merchants before general availability. Join the list to be one of them.
