Most 3PL warehouse management systems are priced for enterprise operations. The ones built for SMBs are not always upfront about what you're actually paying. Here's a straight comparison of the main affordable options so you know what you're getting before you book a single demo.
TLDR (aka the short version): Zenventory is the strongest under $500 option for multi-client 3PLs. It's the only platform in this range that includes automated billing, a white-label client portal, and built-in flat-rate shipping with no per-client or per-user fees.
Four platforms priced for SMB 3PLs. The table covers starting price, what's included, billing automation, and per-client fees. That last column is where "affordable" software quietly gets expensive.
| Platform | Starting price | Automated billing | shipping | Per-client fees | Unlimited users |
|---|---|---|---|---|---|
| Zenventory | $249/month* | Yes, native | Yes, via ZenShip, its own shipping engine | No | Yes |
| WareGo | $499/month* | Limited Complete integration requires the Pro tier |
Yes | Capped at 10 clients Unlimited requires the Custom/Advanced tier |
No, 10 users max Unlimited requires the Custom tier |
| Easy3PL | $999/month | Unverified | Yes | Unverified | No, 5 users max Unlimited requires the Enterprise tier |
| PackemWMS | Not publicly listed Requires a demo for pricing |

The headline price is rarely the real price.
A lot of WMS platforms charge per client, per user, or per integration. You sign up at $199/month, and six months later, you're at $800 because you added three clients and two warehouse staff. That's not a billing error. That's the model working exactly as designed.
For an SMB 3PL handling multi-client warehouse operations, your revenue scales with clients, but so does your software cost. Which means your margin stays flat no matter how many clients you add. Flat-rate pricing that includes unlimited clients is not a minor feature. It changes the math of growth.
There's also the cost of what's missing. A WMS without billing automation means someone on your team manually tracks picks, calculates storage fees, and builds invoices in a spreadsheet every billing cycle. That labor has a real cost. Add it to the software price, and "affordable" looks very different.
This is where Zenventory stands apart at this price point.
Most platforms in this category rely on manual billing or require a separate tool. Zenventory's billing engine is built directly into the WMS, not added on later. It captures picks, storage, receiving, and accessorial charges in real time, automatically applies each client's rate card, and generates invoices at the end of the billing cycle.
It also syncs with QuickBooks Online. No exports. No re-entry. No missed pallet fees.
For a 3PL billing ten clients a month, that's the difference between a two-day process and a 20-minute one.
New customer pricing starts at $249/month for Starter (standard rate: $499/month). Here's what that includes:
The Growth plan is $399/month for new customers (standard: $799/month), covering up to 50,000 shipments and 3 warehouse locations.
Both plans include automated billing. Neither charges extra per client.
It fits well if you're running 1 to 3 warehouses with 5 to 50 clients, currently billing in spreadsheets, or using ShipStation as a separate tool. Zenventory replaces both and costs less than they do combined.
It's not the right fit for enterprise operations with 50-plus warehouse locations or complex cross-dock requirements. Those operations typically need something like Extensiv.
For SMB 3PLs that need multi-client inventory and order management, automated billing, and built-in shipping in one platform, nothing else in this price range is close.
