How to Sell Software to 3PLs: An Outbound Playbook for 3PL Warehouses
To sell software to 3PLs, email the owner or the head of operations at warehouses that just changed shape: a new building, a big new ecommerce client, a WMS switch or a private equity deal. Pitch the margin problem those changes create (billing leakage, mispicks, onboarding time) and time the ask so go-live lands well before the October to December peak. Most pages that rank for this query are written for 3PLs selling their own warehouse services. This one is for vendors selling into them: WMS add-ons, billing and invoicing tools, labor and robotics, shipping software, ecommerce integrations and lead gen. It covers who signs, how buying works around peak, where to find accounts and the emails that get replies.

Quick answer
- At a 3PL with one to five buildings, the owner or president signs almost everything. Above that, the VP of operations owns the problem and the CFO or CEO signs.
- Sell into the margin math. 3PLs bill clients for storage, receiving, picks and special projects, so anything that recovers unbilled work or cuts labor per order gets attention.
- Time it around peak. Few 3PLs will touch their WMS or floor process between October and early January, so book first meetings in Q1 and Q2 and aim for go-live by late summer.
- Watch for new buildings, new ecommerce clients, WMS job posts and acquisitions. Each one changes the workload in a way your product can fix.
- Name the WMS in the first email. A 3PL running Extensiv, Deposco or Logiwa wants to know you plug into it before anything else.
- Expect about 1 meeting per 100 emails when the message rides a real account signal, and closer to 1 per 200 when it does not.
Who actually buys at a 3PL
A 3PL (third-party logistics provider) stores and ships goods for other companies. The warehouse-based ones are the software buyers. Freight brokers and asset-based carriers are a different sale. IWLA, the trade group for warehouse-based 3PLs in North America, describes its members as companies running warehouses for clients, and that is the profile to target.
Size changes everything. Extensiv's 2024 benchmark of more than 250 3PL warehouses found that 51% of operators run 2 to 5 warehouses. Most of the market looks like that: founder-led, often family owned, with an owner who still walks the floor and signs every contract over a few thousand dollars. National 3PLs with dozens of buildings buy like enterprises, with IT, procurement and pilots at one site.
| Title | What they care about | How to approach |
|---|---|---|
| Owner, president or CEO | Margin per client, cash, keeping big accounts | Lead with dollars recovered or labor saved per month |
| VP or director of operations | Throughput, accuracy, overtime, peak readiness | Lead with orders per labor hour and mispicks |
| General manager (site) | Hitting client SLAs in one building | Use as an influencer and pilot owner, not the signer |
| CFO or controller | Billing accuracy, close time, client disputes | Lead with unbilled activity and invoice time |
| IT director or WMS admin | Integrations, EDI, uptime | Bring an integration list and an API doc, not a pitch |
At small and mid-size 3PLs, the VP of sales or business development is a separate buyer. They want more ecommerce and B2B clients, so they buy lead gen, quoting tools and integrations that help them win accounts. If your product helps a 3PL win clients, sell to them. If it cuts cost on the floor, they will forward you to operations.
How 3PLs buy
The calendar runs around peak
For most 3PLs with ecommerce clients, the year is built around Q4. From October into January the floor is at full capacity and leadership will not risk a system change. Treat that window as a research and list-building period. Q1 is when owners look at the damage from peak: overtime bills, chargebacks, the client who nearly left. That is the best time for a first meeting. Contracts tend to sign in Q2 so implementation can finish by August or September.
B2B and food-grade 3PLs have flatter calendars but their own crunch points, such as seasonal produce or retail resets. Ask about their busiest month on the first call and plan around it.
The systems they live in
The WMS is the center of a 3PL's tech stack, and it decides whether your product is even possible. Extensiv (formerly 3PL Central), Deposco, Logiwa, Infoplus and Softeon are common in the small and mid-size market. Larger operators often run Manhattan or Blue Yonder. Around the WMS sit shipping software such as ShipStation or EasyPost, EDI providers for retail clients and storefront connections to Shopify and Amazon. If you integrate with the WMS, lead with that. If you do not, say so early and explain how data moves, because the WMS admin will ask on the first call.
Billing is where the money leaks
3PLs charge clients for each pallet stored, carton received, pick, pack and kit. A lot of that work goes unbilled when it is tracked on paper or in a spreadsheet. Extensiv's 2024 report found that 3PLs spending under 16 hours a month on billing were 2.8 times more likely to report high profitability growth. If your product touches billing, accuracy or labor tracking, that is your opening.
Trade events and associations
IWLA's Convention and Expo is the main gathering for warehouse 3PL owners. The 2026 event ran March 29 to 31 in San Antonio, and IWLA lists the 2027 event for May 2 to 4 in Puerto Rico. MODEX and ProMat, run by MHI, draw operations and engineering buyers in alternating years. Email 3PLs on the attendee and exhibitor lists two to three weeks before the show to set a meeting, then follow up in the week after.
Demand is still growing
Ecommerce keeps pushing more volume into outsourced warehouses. The Census Bureau reported US retail ecommerce at $340.2 billion in Q2 2026, 17.1% of total retail sales and up 12.2% on the year before. More online orders mean more small-parcel picks, which is the work 3PLs struggle to staff and bill well.
Where to find 3PL accounts and timing signals
No public directory lists every 3PL, so build the list from a few sources and then filter hard for signals.
- IWLA's member and partner directory, plus exhibitor lists from IWLA, MODEX and ProMat.
- WMS partner pages and app marketplaces, where some vendors list 3PL customers and integrations.
- Shopify and Amazon fulfillment partner listings, which surface ecommerce-focused 3PLs that market to brands.
- Local business journals and commercial real estate news for new warehouse leases and openings.
- LinkedIn company pages with 20 to 500 employees and terms like fulfillment, 3PL, contract warehousing or ecommerce fulfillment.
Then look for the change that makes now the right time:
| Signal | Where you see it | Why it matters |
|---|---|---|
| New building or lease | Press release, CRE news, LinkedIn | A second site doubles billing and labor problems |
| Big new client announced | 3PL blog, client case study | Onboarding pressure and new SLAs |
| WMS job posts | Job boards (WMS admin, implementation) | System change in progress or planned |
| Acquisition or PE deal | Deal news, press release | New owner wants margin and standard tools |
| Peak hiring posts | Job boards in August to October | Labor cost is top of mind |
| New VP ops or CFO | LinkedIn job change | New leaders buy in their first 90 days |
Messaging that works with 3PL buyers
3PL owners get pitched by staffing agencies, forklift dealers, freight brokers and every WMS add-on in the market. Specific beats clever. Name their building, their WMS or their client mix, and attach one number they can check against their own P&L.
Angles by persona
- For owners, talk margin per client. Show how much billable work goes uncaptured at a 3PL their size and what it would mean across their client list.
- For operations leaders, talk orders per labor hour, mispick rates and how the floor will hold up next peak.
- For CFOs and controllers, talk hours spent on month-end billing and the number of client invoice disputes.
- For sales leaders at 3PLs, talk about winning more DTC brands. Brands choose 3PLs on integrations, speed and visibility, so tie your product to that.
Example email to an owner after a new building
Subject: the Reno building
Hi Dana, congrats on opening the Reno building in September.
A second site usually doubles month-end billing, and receiving and kitting work starts slipping off invoices.
We pull billable activity straight from Extensiv and build the invoice run for you, across both buildings.
Worth 15 min in January, once peak is behind you?
Follow-up, 2-3 days later: Bumping this. Want to see what we'd flag in one month of Reno activity?
Example email to a 3PL sales leader about quoting
Subject: Columbus quote turnaround
Hey Marcus, your site says the new Columbus building has space open for DTC brands this quarter.
Most 3PL sales teams still price storage, pick-pack and kitting in spreadsheets, so answering a brand's RFP takes a week.
We turn your rate card into a quote builder, so reps send a priced proposal the same day.
Interested?
Follow-up, 2-3 days later: Bumping this. Happy to load your rate card and quote one sample brand for Columbus.
What to avoid
- Pitching in October or November with a request to go live before the holidays.
- Generic supply chain language. A 3PL owner can tell in one line whether you know the difference between a 3PL and a shipper.
- Leaving the integration out. If they cannot picture your product talking to their WMS, they will not take the call.
- Sending the same email to the owner, the GM and the ops lead at a 40-person company on the same day. They sit in the same office.
Channels and sequence
Cold email does most of the work here because 3PL leaders are on the floor much of the day and rarely pick up unknown numbers. A sequence we would run:
- Day 1: signal-based email to the owner at smaller 3PLs or the VP of operations at larger ones.
- Day 4: short follow-up in the same thread with one new fact, such as the WMS you integrate with.
- Day 8: email a second contact (CFO or GM) with a different angle tied to their job.
- Day 10 to 14: a call to the main contact's direct line if you have it, and a LinkedIn connection with no pitch.
- Around trade shows: an invite to meet at IWLA, MODEX or ProMat two to three weeks out.
On numbers, plan for about 1 meeting per 100 emails when the email rides a strong signal like a new building, and about 1 per 200 on a generic message. Worst case is closer to 1 per 500. Our cold email statistics show 82% of positive replies come from the first email, so most of the effort should go into email one. They also show CEOs at small companies are about 3 times more likely than VPs to reply positively, which fits the owner-led 3PL market well.
Common mistakes when selling to 3PLs
- Treating every logistics company as a 3PL. Freight brokers, carriers and shippers with their own warehouses all buy differently.
- Selling a feature list to an owner who wants a payback period in months.
- Ignoring the client side. Many 3PL buying decisions are reactions to what a big client demanded, so ask who is pushing for the change.
- Running a one-site pilot at a national 3PL with no plan for how it spreads to other buildings.
- Going quiet after peak. The January follow-up is often the one that books the meeting.

Frequently asked questions
Who is the decision maker at a 3PL?
At 3PLs with one to five warehouses, usually the owner or president. At larger operators, the VP of operations owns the problem and the CEO or CFO signs. IT or the WMS admin has a veto on anything that needs an integration.
When is the best time of year to sell to 3PLs?
January through June. Most 3PLs with ecommerce clients freeze system changes from October through the holidays, so book first meetings early in the year and plan go-live for late summer.
Do I need to integrate with their WMS?
For most floor and billing tools, yes. Name the WMS platforms you support (Extensiv, Deposco, Logiwa and so on) in your first email, since that is the first thing an operations leader checks.
How do I find a list of 3PLs?
Combine the IWLA directory, trade show exhibitor lists, Shopify and Amazon fulfillment partner listings and LinkedIn company searches, then filter for signals like new buildings and WMS hiring.
How many meetings should cold email book with 3PLs?
Plan for about 1 meeting per 100 emails on strong account signals and about 1 per 200 on generic messaging. The 3PL market is small, so signal quality matters more than volume.
Should I go to IWLA or MODEX?
IWLA is the better room for 3PL owners and executives. MODEX and ProMat are larger and draw more engineers and operations staff from shippers as well as 3PLs. Either way, book meetings by email before the show.
