The first 90 days in a new territory set the tone. A simple plan: learn the accounts and relationships, prioritize and build a plan, then execute and win early, plus the mistakes to avoid.
The short version
- The first 90 days set the patterns, relationships, and pipeline that shape your whole tenure in a territory.
- Days 1 to 30: learn. Study the data and meet the people before you try to sell anything.
- Days 30 to 60: prioritize and build a written territory plan, since not every account deserves equal attention.
- Days 60 to 90: execute and get a few early wins for momentum, while protecting the base you inherited or built.
- Avoid the classic mistakes: selling before understanding, treating all accounts the same, and running with no plan.
A new territory is a fresh start and a test at the same time. Whether you are new to medical sales or a veteran taking over a new patch, the first 90 days shape how the rest of your time there goes: which relationships you build, which opportunities you find, and how quickly you start putting points on the board.
The reps who ramp fast are not winging it. They run a plan. Here is a simple one, broken into the three months that matter most.
01Why do the first 90 days matter so much?
Because you are setting patterns and first impressions that stick. The customers you meet early form their read of you fast, the accounts you prioritize shape your pipeline for the year, and the habits you build in month one tend to be the habits you keep. Start with intention and the territory compounds in your favor. Start by reacting to whatever lands in front of you and you spend the year behind.
It matters whether you inherited a strong book or a neglected one. A strong territory has relationships to protect and a standard to maintain. A weak one has low-hanging fruit and room to grow. Either way, the first move is the same: understand what you actually have before you try to change it.
02What should you do in the first 30 days?
Learn. Resist the urge to sell before you understand the territory, and spend the first month absorbing everything. Study the data: who your accounts are, what they buy, where the volume is, and where it has slipped. Get into the field and meet people, the physicians, the OR and office staff, the schedulers, and listen more than you talk.
This is also relationship groundwork. Introduce yourself as the new rep, learn how each account likes to work, and start earning trust before you ask for anything. The information and goodwill you gather now is what every later decision will run on.
03What should you do in days 30 to 60?
Prioritize and plan. Now that you know the territory, decide where your time creates the most value. Segment your accounts: the high-value relationships to protect, the growth opportunities to pursue, and the accounts not worth heavy investment right now. Not every account deserves equal attention, and pretending otherwise is how reps spread themselves thin.
Then build a real territory plan, a written map of which accounts you are targeting, at what call frequency, and why. This is the difference between a rep with a system and one who just drives around. Your plan turns the month of learning into a month of focused intent.
04What should you do in days 60 to 90?
Execute and win early. With a plan in hand, get to work on the priorities and go after a few early wins, because momentum and credibility matter. A first case converted, an account reactivated, a stalled opportunity moved forward, these prove to your customers and yourself that the territory is moving. Early wins also buy you patience for the bigger opportunities that take longer.
Keep protecting the base while you pursue growth. The relationships you inherited or built in month one need consistent attention, so do not chase new business at the expense of the accounts already counting on you. By day 90 you should have a working plan, a few wins, and a clear read on where the year's growth will come from.
05What mistakes sink new-territory reps?
The big one is selling before understanding. Reps who come in hot, pushing product before they know the accounts, burn goodwill and miss what the territory actually needs. Close behind is treating every account the same instead of prioritizing, and neglecting the base while chasing shiny new logos.
The other trap is having no plan at all, just reacting to whatever calls come in. A territory run on reaction never builds momentum. Spend the first 90 days learning, prioritizing, and executing on purpose, and you set up not just a good quarter but a strong tenure.
Frequently Asked Questions
What should a medical sales rep do in the first 90 days?
Spend the first month learning the accounts, data, and relationships; the second prioritizing accounts and building a written territory plan; and the third executing on priorities and securing early wins while protecting the base. Understand the territory before trying to change it.
How do you take over a new sales territory?
Start by understanding what you have. Study the account data, meet the physicians and staff, and listen before selling. Then segment and prioritize accounts, build a written plan, and pursue a few early wins for momentum. This works whether you inherited a strong book or a neglected one.
What is the biggest mistake in a new territory?
Selling before you understand the territory. Reps who push product before knowing the accounts burn goodwill and miss what the territory needs. Other common mistakes are treating every account the same, neglecting the inherited base, and operating with no plan at all.
How long does it take to ramp up in a new medical sales territory?
The first 90 days establish the foundation, learning, planning, and early wins, but full ramp usually takes longer as bigger opportunities mature. A disciplined first quarter of understanding and prioritizing accelerates everything that follows.
