Software Integration Guide for a 3PL Operator

Ask which tools in a 3PL stack actually integrate, and the honest answer is: almost everything connects to Google Workspace, most finance tools connect to QuickBooks Online, and only a short list — ShipStation, Scandit, Stripe, and QuickBooks Online itself — connect directly to a WMS at all. Everything else, including your entire sales and marketing pillar, lives in its own silo relative to the warehouse floor.

The two hubs

Google Workspace and QuickBooks Online are the two nodes almost everything else connects through — but neither reaches the warehouse floor.

Google Workspace connects directly to 1Password, DocuSign, Gusto, and Huntress — the widest reach of any tool in the stack, which is exactly why it's priced as the operation-wide productivity layer at $170/mo rather than a per-department tool. QuickBooks Online connects directly to Gusto, Ramp, Bill.com, Stripe, and ShipHero — it's the finance cluster's hub, and the one place client storage and handling billing is supposed to land before your bookkeeper closes the month. Notice what's missing from that list: Extensiv and Deposco aren't in it, even though both list QuickBooks Online as an integration on their own side.

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

Stripe's own integration list names ShipHero specifically, not Extensiv or Deposco — so if you're running client payments through the portal on either of the other two platforms, that reconciliation between card payments and the WMS billing module is more likely a manual step than an automatic one. And as covered in the ShipHero-vs-Extensiv cost breakdown, QuickBooks Online's own list only confirms ShipHero back, even though Extensiv and Deposco both claim the connection from their side. That's not a reason to default to ShipHero on its own — but it's a real factor if your bookkeeper's time is the thing you're trying to save.

The finance cluster runs on its own, mostly

Gusto, Ramp, and Bill.com all connect to QuickBooks Online and to each other, but none of them connect directly to the WMS — which is normal, since payroll and vendor bill-pay have no reason to touch inventory data. It does mean the one place client revenue actually reconciles against payroll and expenses is QuickBooks Online, fed by the WMS billing export. If that export is manual — more likely on the Extensiv or Deposco side, given the one-sided QuickBooks listing — your bookkeeper is the integration, not the software.

Security tools protect the endpoint, not the WMS

1Password and Huntress connect to each other and to Google Workspace, not to the WMS directly. In practice, that means your password manager and endpoint detection cover the devices office staff and floor supervisors use to access the WMS — they don't give you visibility inside the WMS's own access logs, which stays the WMS vendor's job. DocuSign connects to Google Workspace and to HubSpot CRM — useful for routing a signed service agreement straight from a closed deal, but it's still a two-spoke connection, not a stack-wide integrator.
