Your Open Enrollment Was Chaos Last Year Because It Started in October. It Should’ve Started in June.

You remember last October. The rates came in late. The broker was slow to call back. You were building the employee guide the same week enrollment opened, fixing the deduction file while people were already asking why their paycheck looked wrong, and answering the same five questions forty times because nothing went out early enough to land.
It felt like the season did that to you. It didn’t. The chaos didn’t start in October. It started in June, when nobody was looking at open enrollment yet, because it felt like a fall problem. By the time it felt urgent, every good decision was already a rushed one.
Open enrollment isn’t an event. It’s the last two weeks of a project that should already be months old. Here’s the timeline that turns October from a fire drill into a formality.
Why “October” Is Already Too Late
Here’s the trap that catches every new admin: open enrollment feels like a fall thing, so planning feels like a fall thing. But by fall, the decisions that actually matter are already behind you. Your renewal rates, your plan changes, your contribution strategy, your vendor setup โ those get locked months before a single employee logs in. If you start when enrollment opens, you’re not running open enrollment. You’re reacting to it.
The fix isn’t working harder in October. It’s starting in June, doing a little each month, so that by the time the window opens, the hard part is already done and all that’s left is communication. Below is the runway, month by month, working backward from a January 1 plan year. If your plan year is different, shift the months but keep the spacing.
The 6-Month Renewal Runway

Each stage has one job. Do that job in its month and the next one gets easier.
JuneโJuly (5โ6 months out): Look back before you look forward.
Before you can plan next year, understand this year. Pull your claims and utilization data, note what drove costs, and flag what frustrated employees. Get on your broker’s calendar now for a renewal strategy conversation โ not in September when they’re slammed with every other client who also waited. This is the month to ask, “what’s coming at renewal, and what should we be thinking about?”
August (4 months out): Get your renewal and run the numbers.
Your renewal rates and any plan changes land around now. This is the real work: model what the new rates do to both the company budget and the employee paycheck, decide your contribution strategy, and โ this is the one new admins skip โ re-run your ACA affordability check against the new employee contributions. The number the IRS uses changes yearly, and your new rates have to pass it.
September (3 months out): Lock decisions and build the system.
Final plan lineup and contributions get approved. Now you build the machine: confirm everything in your benefits administration system, set up the enrollment event, and test it before a single employee touches it. Build your communication calendar this month too โ what goes out, when, and to whom. The goal is that nothing gets built during the open window; it’s all ready to fire.
October (1โ2 months out): Communicate, don’t scramble.
This is when most admins start. You’ll be finishing. Your only job now is getting clear, plain-English communication out the door โ early and in pieces, not one giant guide the week before. If your messaging is built around what employees actually need to decide, you cut the repeat-question flood dramatically. (I put my exact templates in a free kit โ Steal My Open Enrollment Emails โ so you’re not writing them from scratch in your busiest month.)
November (enrollment window): Run it, watch it, nudge it.
The window’s open. Monitor completion daily, send your reminders, and chase the stragglers โ because almost half of people wait until the final two days, and a chunk never act at all unless you nudge them. This is execution, not decision-making, because you made the decisions in August and September. That’s the whole point of the runway.
DecemberโJanuary (the close): Verify before you exhale.
Don’t file OE under “done” when the window closes. Confirm elections fed correctly to payroll and the carriers, reconcile a sample of deductions before the first January paycheck runs, and watch for the elections that don’t carry over. The cleanup is its own discipline โ I walk through it in the post-OE audit, because the close is the half of the race nobody warns you about.
Put the Whole Thing on One Calendar

A timeline only works if it lives somewhere you’ll actually see it. The single highest-leverage thing you can do is put every one of these stages โ with the deadlines, owners, and dependencies โ into one running calendar you check weekly. Some people use a wall calendar, some a spreadsheet. I build mine in a project tool so the deadlines ping me before they’re urgent; ClickUp has a free plan that handles recurring benefits deadlines well, and the reminders are the part that saves you. (That’s an affiliate link โ I only point you to tools I actually use.) Whatever you use, the rule is the same: if a benefits deadline only lives in your head, it will find you in October.
What Usually Goes Wrong
Before the list, the pattern: every one of these is a calendar problem wearing a different costume. The work isn’t hard when it’s spread across six months. It’s brutal when it’s crammed into two weeks.
โข Planning starts when enrollment opens, so every decision becomes a rushed one.
โข The broker conversation happens in September, when they’re buried, instead of June, when they have time for you.
โข New contributions get set without re-running the affordability check, setting up a compliance miss.
โข The enrollment system gets built and tested during the open window instead of before it.
โข Communication goes out late and all at once, so the repeat-question flood never lets up.
Last year’s chaos wasn’t a personal failing and it wasn’t bad luck. It was a start date. The admins who seem calm in October aren’t working harder than you โ they started in June and did a little each month. The work is the same either way. The only choice is whether you spread it across six months or survive it in two weeks. Pick the calendar.
Where to Start This Week
Run open enrollment like a system, not a season. If you want the whole thing built for you โ the full timeline, the rate and contribution math, the decision tools, and the checklist that walks you through every phase โ that’s exactly what the Open Enrollment Mastery Kit is. It’s the system I wish someone had handed me before my first October.
Get your communication done before crunch time. Grab Steal My Open Enrollment Emails โ five copy-paste templates so October’s messaging is ready in June.
Put it on one calendar. Drop all six stages into a tool that reminds you before deadlines bite. ClickUp’s free plan handles recurring benefits deadlines well.
Plan for the close, too. When the window shuts, the post-OE audit is how you make sure everything you set up actually landed.
October will come whether you’re ready or not. The difference between a fire drill and a formality is four months and a calendar. Start now.
