E-commerce and DTC brands switch to a new 3PL when repeated service problems start affecting orders and growth. January to March can be a good time to plan the move. Because the holiday rush has just started to slow down.
But whenever you decide to switch to a third-party logistics (3PL), the switch takes a 30-day evaluation plus 8-12 weeks of transition.
For teams trying to find 3PL customers, timing matters because brands are more open to conversations before evaluation and transition windows begin. That’s why 3PL sales teams get 2 outreach seasons-
- Prospect in July-September for winter moves.
- Late January-March for summer moves.
So, adjust those windows to each brand’s contract and the time needed to transfer inventory and connect systems.
Why Do You Need to Switch 3PL at the Right Time?
Switching your 3PL at the right time helps you keep orders moving, protect your profit, and avoid disappointing customers. If your current fulfillment provider keeps making mistakes, waiting can cost you more. But moving during your busiest weeks can create a whole new set of problems.
That’s why you need enough time for inventory transfers, system connections, and test orders. A quieter sales period gives both teams more room to complete that work before order volume rises.
The right time also helps because:
- Late or incorrect deliveries can lead to complaints, refunds, and customers deciding not to buy again.
- Moving during Black Friday, Cyber Monday, or another sales peak can make backlogs and missing stock harder to resolve.
- Repeated picking errors, extra fees, and slow shipping can reduce the profit you make on each order.
- Planning early gives you more choice over the move date and time to confirm the new provider’s onboarding capacity.
But a quieter month alone is not a reason to leave. Don’t jump into a decision to change the 3PL. It’s a hassle, so change only for valid reasons. Change your 3PL if you see-
- Missed SLAs
- Limited capacity
- Poor communication
- Rising shipping costs
If those problems continue after you raise them, start comparing providers. Then work back from your preferred move date. See the contract’s notice period and the new warehouse’s setup time.
January to March may suit some brands, but your own order calendar should guide the decision.
How Long is the 3PL Sales Cycle?
A brand may need about 3 to 4 months to choose a new 3PL and move its operations. Sounds too long because it combines Forthmatch’s 30-day evaluation period with Green Fulfilment’s 8 to 12 weeks for transition.
But it is just an idea, not a fixed time. Your brands may need more or less time to completely switch to a new 3PL. The transition times vary by 3PL provider as well, for example-
- DSCP suggests 4 to 12 weeks.
- IDS Fulfillment gives 9 weeks.
So, the actual time depends on inventory, integrations, and the work involved.
So, your sales team needs to start outreach early with good logistics cold-calling scripts. Because the clock starts when a brand begins checking or talking to other providers. It does not include the time you spend reaching the buyer, so knowing who to contact when selling 3PL services can help you get into the conversation earlier.
So, work back from the brand’s planned go-live date. Leave room for evaluation and transition, then begin outreach before those stages.
To speed up the process, have your pricing, supported integrations, and two relevant client references ready for the first meeting. You can answer buyers’ main questions early and reduce delays caused by missing information.
3 Timeline to Switch 3PL
Switching 3PL timelines vary by brand and needs. So far, we have found 3 types:
The Winter Move Timeline
Evaluation would start between December 7 and January for a brand aiming to go live by March 31, 2027. Use the 30-day evaluation and 8- to 12-week transition estimates.
Your sales team can start outreach in July to September to get into the conversation before the holiday rush. The window kinda looks like this-
| Step | Calculation | Date |
| Go-live target | End of the Q1 window | March 31, 2027 |
| Transition starts | March 31 minus 12 weeks or 8 weeks | January 6 or February 3, 2027 |
| Evaluation starts | Minus 30 days | December 7, 2026 or January 4, 2027 |
| Outreach lands | Before brands go quiet at peak | July–September 2026 |
A January 1 go-live would put the transition during the holiday peak. If you choose the date, then also plan around busy warehouses, ongoing orders, and any applicable carrier surcharges.
Even with a March target, evaluation may overlap with December trading. Keep meetings focused and send pricing, integration details, and answers afterward. So the buyer can review them between other tasks.
The Summer Move Timeline
Red Stag Fulfillment says it is best to switch 3PL running 60 to 90 days before peak season. In that case, use September 27, 2026, when UPS peak pricing starts. However, it works only for a few brands. So do a cross-check before making any decision. To make it easier, set the go-live window between June 29 and July 29, for example:
| Step | Calculation | Date |
| Go-live cutoff | September 27 minus 90 days or 60 days | June 29 or July 29 |
| Transition starts | Minus 12 weeks or 8 weeks | April 6 or June 3 |
| Evaluation starts | Minus 30 days | March 7 or May 4 |
| Outreach lands | After carrier peak ends in mid-January | Late January–March |
Adjust both timelines around the brand’s busiest months.
Forthmatch recommends starting migration by July for gift brands with heavy Q4 sales. Gift, apparel, beauty, supplement, and other online brands can have very different peak periods. That is why winning ecommerce fulfillment leads start with understanding each brand’s order cycle before suggesting a move date.
Your outreach also should be around the timeline as in-
- From July to September, discuss a fresh start after the holiday rush.
- with preparation in December and the move in January if the brand’s schedule allows.
- Then focus on completing the move early enough to test systems and settle in before the next busy season, from late January to March.
The Summer Switching Window
May to July can work for brands that missed the Q1 window and have lower order volumes in summer. But check the brand’s own sales calendar first. Some brands, like Sunscreen, swimwear, and camping brands, may be too busy during these months to move safely.
If you are a summer-selling brand, then don’t move your 3PL in the summer.
This means you should plan the move in the first half of the year. Because brands need time to compare providers, agree on pricing, and plan the inventory transfer before summer arrives.
That’s why you need to start 3PL lead generation early so you can reach out early and plan a successful transition. Start by identifying brands that fit your warehouse, order profile, and service area. The same targeting process used to find 3PL customers can help you build a list before the seasonal outreach window opens.
A Month-by-Month 3PL Prospecting Calendar
Focus more outreach in February and August, and plan for evaluation discussions in March and December. Build your 3PL prospect list before the heavier outreach months so your reps already know which brands to contact when those windows open.
During a brand’s busiest months, keep follow-up brief. Here is an example calendar you can follow to plan outreach correctly and set logistics appointment-setting benchmarks:
| Month | What brands are doing | What sellers do |
| January | Peak pricing ends January 16–17. Q1 transitions begin. | Start summer-move outreach after mid-month. |
| February | Q1 transitions run. Summer movers start planning. | Peak summer-move outreach. |
| March | Q1 go-lives. Summer evaluations open on March 7. | Run meetings and send proposals. |
| April | Summer transitions start on April 6. | Close summer deals. |
| May | Last summer evaluations open by May 4. | Final summer closes. |
| June | Latest summer transitions start June 3. | Build Q3 target lists. |
| July | Summer go-live cutoff, June 29 to July 29. Peak planning starts. | Launch winter-move outreach. |
| August | Peak plans locked. | Heaviest winter-move outreach. |
| September | UPS peak pricing starts September 27. | Book meetings before September 27. |
| October | FedEx peak pricing starts October 26. | Light touches, log contract dates. |
| November | Peak. | Light touches, set January meetings. |
| December | Peak. Winter evaluations start December 7 to January 4. | Run evaluation calls for winter movers. |
The Worst Months to Switch a 3rd-Party Logistics (3PL)
October to December is usually a difficult time to move for brands with heavy holiday sales. Your old warehouse still needs to ship orders, and the new one needs time to receive stock, connect systems, and test the setup.
That’s why you need a different plan for those months too.
A move may still work, but you need enough time to settle in before your own peak starts. Avoid treating all 3 months as equally unsuitable.
The main risks are:
- Moving stock during Black Friday or Cyber Monday can leave products unavailable just as customers want to buy.
- Busy warehouse teams may have less time for onboarding, inventory checks, and system testing.
- A late transition leaves little room to fix receiving delays or integration problems before orders increase.
- Missed deliveries can lead to refunds, cancellations, and wasted advertising spend.
That’s why January to March may offer more room to move for brands that slow down after the holidays.
If stock levels are lower, there is less inventory to count and transport. Confirm the new provider’s capacity before choosing a date, though. Post-holiday returns and other client launches may still keep its team busy.
Oh, and another thing: Lunar New Year can also affect inbound shipments.
So keep that in mind, and use your supplier’s actual production and shipping schedule to plan around it.
But if your current 3PL is losing stock or leaving orders unshipped for weeks, waiting may cause more damage. An urgent move needs confirmed receiving space, a stock-transfer plan, and a clear agreement on which warehouse will ship orders during the change.
What to Do During Peak Season?
If a prospect says “call me after peak,” do not push for an immediate meeting. Treat it like other 3PL sales objections, agree on a follow-up date, and save the brand’s contract end date and notice period.
During peak, keep contact brief. One useful email a month may be enough. In December, offer a January meeting, but let the buyer choose a date that fits their workload. Carrier peak pricing ends in mid-January, though the brand’s busy period may end earlier or later.
Basically, do this:
- Log every contract end date and notice period in your CRM.
- Send one useful touch a month, such as a note on surcharge dates, using logistics cold email templates.
- Book January meetings during December, for the week after peak pricing ends.
- Build your summer-move target list before January.
- Share one short case result from a past peak instead of a pitch.
- Ask each prospect when its own peak ends.
Plan outreach around each brand’s busiest months. Because brand needs change depending on the reason and the brand’s product.
Like a supplement brand may see a January rush, and B2B or wholesale orders may follow customers’ buying schedules. So, find out when their orders rise before suggesting a move date.
Your own peak-season performance can help with those conversations. If your team handles the rush well, record the results and get the client’s permission to use them as a reference in January.
Set your follow-up dates around the buyer’s plans. Your monthly sales target doesn’t change how long they need to move.
Final Thoughts
Check your own warehouse’s onboarding schedule before promising a move date. Several brands may want to start in the same month, but each needs staff time, receiving space, and system testing.
Share available start dates with your sales team and update them as accounts sign. That helps reps offer a date your operations team can actually support.
