Finish Line Technologies

A summary of how Finish Line Technologies, a US maker of specialty bicycle lubricants and maintenance products, connected a new Shopify store to Acumatica with InSyncer — including a solution to US sales tax sync that didn’t require a third-party tax engine.

Challenge

Section titled “Challenge”
  • Launching a new direct-to-consumer Shopify storefront connected to an existing Acumatica ERP.
  • Needed orders, inventory, and refunds flowing without manual re-entry.
  • Shopify’s native Acumatica connector was overriding product data, variants, pricing, and images — causing two months of delays.
  • Shopify Tax calculates tax by jurisdiction (city, county, state), and those jurisdictions weren’t pre-configured in Acumatica — orders were failing. For Acumatica merchants selling across the US, Avalara is the typical solution for this. But Finish Line was Nexus in New York only — a full tax engine was more than they needed at this stage.

Solution

Section titled “Solution”

CyberWorkshop deployed InSyncer to bridge Shopify and Acumatica, with Mayer Group ERP (Acumatica Gold Partner) handling the Acumatica side. Project management was led by Frictionless.

Tax without Avalara: InSyncer’s Tax Amount Override was used to pass Shopify’s calculated tax total directly into a single Acumatica tax ID (SHOPIFY). This bypasses Acumatica’s jurisdiction-level tax validation entirely — Shopify remains the source of truth for tax calculation and reporting, while Acumatica records the correct dollar amount on each order. No external tax engine required.

Key elements:

  • Real-time order sync from Shopify to Acumatica
  • Inventory levels pushed from Acumatica to Shopify
  • Refund and fulfillment sync back to Shopify
  • Tax Amount Override to pass Shopify-calculated tax into Acumatica without jurisdiction mapping
  • Custom functionality built to match Finish Line’s specific workflows

Results

Section titled “Results”
  • New Shopify store went live with Acumatica fully connected through InSyncer.
  • Tax sync resolved without Avalara or manual jurisdiction setup in Acumatica.
  • Deployed in a fraction of the time spent on the native connector — no business interruption.
  • 5-star review on the Shopify App Store: “App does what you need it to. They were able to add additional functionality to meet specific needs of our company. No issues yet. Their service though, is what I was most impressed by.”
