Looking for an SPS Commerce alternative?
InfiPlex publishes full pricing starting at $49.99/month, flat, no per-document charges. SPS Commerce doesn't publish base pricing and bills per document exchanged, one BBB complaint cites an average of $2.26 per document, on top of setup fees and a subscription SPS considers valid whether or not you're actively using it.
SPS Commerce
- Base pricing undisclosed, billed per document exchanged
- Multiple reviewers report billing disputes and unexpected fees
- EDI only, marketplaces need a separate tool
What changes
- Published pricing from $49.99/mo, flat, no per-document fees
- One connection for EDI and 130+ marketplaces
- Missing channels built free on Growth plans
What the pattern actually looks like
The billing complaint shows up as a specific, recurring shape: a per-document rate that's hard to know in advance, layered with setup fees and a subscription that one support response described as valid "even if the service is not being utilized." Reviewers on GetApp, Capterra, and Software Advice separately describe high fees, confusing billing, and charges that accumulate faster than expected as a trading-partner network grows. And because SPS Commerce is EDI-only, a seller who also sells on Amazon, Walmart, or TikTok Shop is typically running a second platform alongside it just to manage those channels.
Three questions worth asking SPS Commerce directly
None of these require special access, they are ordinary due-diligence questions any serious vendor should answer plainly before a contract is signed.
What's the actual cost per document, and does it change by volume or trading partner?
Ask for the exact per-document rate in writing for each specific retailer you'll be connecting to, not a blended average.
Is there a published price list, or does every quote require a sales call?
Ask to see current published pricing. Every major review site notes SPS Commerce does not publish it.
If a document is billed in error, what's the credit process and timeline?
Ask specifically how duplicate or miscounted document charges get resolved, and how long that typically takes, in writing.
Four concrete differences, not marketing language
Published pricing, not per-document billing
Before: undisclosed base cost, billed per document$49.99, $499.99, or $999.99 per month, published in full, no discovery call needed.
One connection instead of two
Before: EDI only, marketplaces are a separate toolEDI, 130+ marketplaces, and 3PL or NetSuite connections run from the same order queue.
Flat monthly cost, not itemized per transaction
Before: charges scale with every document sentYour monthly cost doesn't move every time order volume moves, so growth doesn't quietly increase your platform bill.
Missing a channel? It's built free
Before: quoted as custom developmentGrowth plans include 2-4 new marketplace API integrations built at no development cost per year.
One number is public. One is billed after the fact.
The $2.26 figure comes from a public BBB complaint describing that seller's average per-document charge, on top of separately-billed setup fees. Base subscription pricing isn't published anywhere, so most sellers only learn the real number after a sales conversation.
The comparison, in one table
| Category | SPS Commerce | InfiPlex |
|---|---|---|
| Pricing | Undisclosed, ~$2.26/document reported | Published, from $49.99/mo flat |
| Billing model | Per document exchanged | Flat monthly |
| Scope | EDI only | EDI + 130+ marketplaces + 3PL/NetSuite |
| How you get access | Often required by a specific trading partner | Chosen directly, published pricing |
Why one connection instead of two?
EDI compliance is only one piece of running a multichannel business. Splitting it across two platforms means reconciling two dashboards, and often two invoices, for every order.
EDI and marketplaces, same order queue
Orders from Target, Costco, or Sam's Club sit next to Amazon, Walmart, and TikTok Shop orders in one place instead of two separate systems.
One inventory pool, not two
Stock committed to an EDI retailer and stock committed to a marketplace draw from the same real-time pool, so nothing gets oversold between the two.
Settlement in one place
EDI invoicing and marketplace payouts reconcile against the same order data instead of two exports you have to line up by hand.
Questions people ask before switching
The goal here is a fair evaluation, not a rushed decision, take these to your own team before committing either way.
Is SPS Commerce more expensive than InfiPlex?
SPS Commerce doesn't publish base pricing, and bills per document exchanged, one BBB complaint cites an average of $2.26 per document plus separate setup fees. Multiple review sites report frequent billing disputes and fees that are hard to predict in advance. InfiPlex publishes full pricing starting at $49.99/mo, flat and month-to-month.
Does SPS Commerce handle marketplaces like Amazon and Walmart?
SPS Commerce is built for EDI trading-partner compliance, not marketplace order management. Sellers who need Amazon, Walmart, TikTok Shop, or similar marketplace connections typically run a separate tool alongside it. InfiPlex covers EDI and 130+ marketplaces from one connection.
What do SPS Commerce reviewers complain about most?
Undisclosed base pricing, per-document fees that are difficult to predict, and billing disputes over duplicate or miscounted documents are the most commonly reported issues across GetApp, Capterra, and Software Advice reviews.
Can I see InfiPlex pricing without a sales call?
Yes, Basic Starter, Growth Starter, and Growth Pro are all published in full on the pricing page, with no sales conversation required to see a number.
Is EDI free with InfiPlex if I switch from SPS Commerce?
Not entirely, retailer-mandated EDI VAN fees are set by the retailer and exist regardless of platform. InfiPlex says it can often reduce or eliminate those costs, in some cases enough to cover the monthly package on its own. What does change is that InfiPlex's own platform fee is flat and published, rather than billed per document like SPS Commerce's.
Why would a seller use SPS Commerce instead of InfiPlex?
Sometimes it isn't optional, a retail trading partner can require suppliers to connect through a specific EDI network. SPS Commerce also operates one of the largest EDI networks in retail, which is a genuine strength for suppliers who only need EDI compliance and nothing else.
