Software Integration Guide for Wholesale Distribution Companies

Ask which tools in a distribution stack "integrate" and the intuitive answer is usually wrong. It isn't the ERP that touches the most of the rest of the stack — it's SPS Commerce, the EDI compliance layer, because it's built to plug into Cin7 Core, Fishbowl, or NetSuite equally rather than lock a distributor into one. QuickBooks Online and Google Workspace are the other two hubs. Outside those three, most tools don't talk to each other at all, which matters because reseller orders, EDI transactions, and warehouse scans all need to reach the same inventory record eventually.

The three hubs

QuickBooks Online, Google Workspace, and SPS Commerce are the three nodes almost everything else connects through.

QuickBooks Online connects directly to Gusto, Ramp, Bill.com, Stripe, and Cin7 Core — the widest reach of any tool in the finance side of the stack, and the place cosmetic-free, straightforward reconciliation is supposed to happen before your bookkeeper closes the month. Google Workspace connects to 1Password, DocuSign, Gusto, and Huntress — notably, it doesn't connect directly to any ERP in this stack, which is a real difference from industries where the productivity suite is wired straight into the core operations system. SPS Commerce is the quiet structural standout: it lists native connections to Cin7 Core, Fishbowl Inventory, NetSuite, and QuickBooks Online — all three ERPs plus the accounting layer — because EDI compliance has to work no matter which inventory platform a distributor already runs.

Where the ERP hub actually reaches — and where it doesn't

Fishbowl is the one ERP with no native Handshake connection — a distributor running Fishbowl who also wants self-serve reseller ordering through Handshake is relying on manual re-entry, not automation, no matter how either sales page describes general 'compatibility.' NetSuite is the mirror case on the finance side: it doesn't connect to QuickBooks Online at all, because NetSuite's own financial module is meant to replace it, not sync with it — if you're comparing NetSuite's price against Cin7 Core or Fishbowl, remember you're also dropping QuickBooks and its $90/mo license, not adding NetSuite on top of it.

HubSpot and the CRM-to-inventory gap

HubSpot CRM connects to Mailchimp and Google Workspace — not to any ERP directly. The only tool that bridges CRM data to inventory at all is Handshake, which lists connections to both HubSpot and Cin7 Core. That means a distributor running HubSpot and Cin7 Core without Handshake has no native path for quote-to-order handoff between sales and inventory; adding Handshake isn't just an ordering convenience in that setup, it's the only listed connective tissue between the CRM and the ERP.

The finance cluster runs on its own, mostly

Gusto, Bill.com, and Ramp all connect to QuickBooks Online and to each other, but none connect directly to the ERP or to SPS Commerce — which is normal, since payroll and vendor bill-pay have no reason to touch inventory or EDI transactions. It does mean the one place sales revenue, freight costs, and payroll actually reconcile against each other is QuickBooks, fed by whatever the ERP exports. Stripe connects to QuickBooks Online and Handshake specifically — it's tied to the B2B ordering portal, not the ERP itself, so a distributor collecting reseller payments outside Handshake is handling that reconciliation manually.

Security tools protect the endpoint, not the warehouse system

1Password and Huntress connect to each other and to Google Workspace, not to any ERP or EDI system directly. In practice, that means your password manager and endpoint detection cover the devices staff use to access the ERP, retailer portals, and the EDI network — they don't give you visibility inside those systems' own access logs. DocuSign connects only to Google Workspace in this map — a useful tool, but a single-spoke one, not a stack-wide integrator.
