7 Common 3PL RFP Mistakes That Cost Brands Time and Money

Most 3PL RFP mistakes happen before the first proposal is even submitted. Here are the ones we see most often, and what they end up costing.

1. Writing a Vague RFP

The most expensive mistake is also the most common: sending an RFP that's missing key details about your product, order profile, or requirements. In one RFP we reviewed, that vagueness produced pricing quotes ranging from $4.20 to $9.75 per order across responding providers, more than double the spread, simply because providers were making different assumptions about the same request. The brand picked a provider based on that scattered pricing, and 18 months later, was already switching 3PLs.

2. Not Following Up

Nearly half of submitted proposals never get any follow-up from the brand that requested them. If you're not planning to seriously evaluate a proposal, don't request one. Every unanswered RFP costs a provider real hours, and it costs you goodwill with providers you might want to work with later.

3. Weighing Price Above Everything Else

Cost is one of four dimensions that determine fit, alongside capabilities, team, and trust, and it's the easiest one to compare, which is exactly why it gets overweighted. The cheapest proposal on paper isn't automatically the right choice if the team behind it, or the trust you'd need to build with them, doesn't hold up.

4. Including Finalists as a Formality

Sometimes a provider makes it into the final round not because they're a real contender, but because someone internally insisted they get a shot. One brand described exactly this: a finalist included because "someone said just give them a chance," when the decision had effectively already been made. That wastes the provider's time and yours, and it dilutes the finalist round with a comparison that was never real.

5. Sending Full RFPs to Too Many Providers

Skipping a fast screening step means sending detailed, full proposal requests to every provider on your long list instead of narrowing first. That multiplies the work on both sides for candidates who were never going to be a fit.

6. Staying Too Long With the Wrong Provider

The flip side of running a bad RFP is not running one soon enough. More than one brand we've talked to has said some version of the same thing: they stayed with their original 3PL too long, past the point where they'd clearly outgrown them, because starting a new RFP felt like more work than tolerating a provider that no longer fit.

7. Ignoring How Fast (or Slow) Providers Respond

Response speed is a signal, not just a scheduling detail. Providers who move fast, responding to first contact within 12 hours, are disproportionately the ones who end up winning. Roughly the top 20% of 3PLs win 80% of all open-market RFPs, and speed to first contact is one of the clearest patterns behind that gap. A provider who's slow or inconsistent during the RFP itself is telling you something about what communication will look like once you're a customer.

The Common Thread

Every mistake on this list comes back to the same root cause: treating the RFP as a formality instead of the actual decision-making process. The brands that get this right spend more time up front on structure, a clear scope, a real screening step, defined criteria, so the back half of the process doesn't have to absorb all the ambiguity they skipped over early.
