See your book's risk concentration before your carrier flags it

You know your book of business better than anyone. You know which clients renewed last month, which ones are shopping around, which ones called about a claim. What you probably don't know — not with any real confidence — is how your policies are clustered on a map.

That gap doesn't matter until it suddenly does. A hurricane forms in the Gulf. A wildfire jumps a ridge. A carrier sends a letter saying they're reviewing concentration in certain zip codes and asking agents to justify their exposure there. And that's the moment you find out whether your book is spread out sensibly or stacked up in one flood plain, one wildfire corridor, or one stretch of coastline you never quite pictured as a single cluster.

Carriers watch concentration risk closely. It's part of why they set appointment terms, adjust commission schedules, or non-renew an agency's contract entirely. If too much of your homeowners book sits inside the same flood zone or wildfire-rated county, that's not just a risk to your clients — it's a risk to your standing with the carriers you depend on.

The problem: you can't see your own book

Most independent agents run their book out of an agency management system. It's great for policy details, renewal dates, and commission tracking. It is not built to show you, visually, where your clients actually live relative to each other.

So when a carrier asks "how concentrated are you in this coastal zone," most agents do one of three things:

• Scroll through a spreadsheet of addresses and zip codes, guessing at geography from memory.
• Look up addresses one at a time in a map on their phone or laptop, which is fine for ten policies and unworkable for four hundred.
• Pay a GIS consultant for a one-time mapping project, which is accurate but expensive, and stale again within a month once new policies are written and old ones lapse.

None of these give you a repeatable answer. And a book of business isn't a snapshot — it changes every renewal cycle. A concentration problem you solved in March can quietly rebuild itself by August as new business comes in from the same neighborhoods, referral chains, and local marketing efforts that built your book in the first place.

What this actually costs an agent

The cost isn't abstract. It shows up as:

• Non-renewal risk from a carrier, if concentration in a catastrophe-prone zone grows without anyone noticing until the carrier's own review catches it.
• Reactive scrambling, where you're pulling together a manual analysis under deadline pressure because a carrier asked for one, instead of already having the answer.
• Missed opportunity to write smarter, because you don't have a clear picture of where your book is thin and where it's already saturated, so you can't steer new business toward better balance.
• Time, plain and simple — hours spent manually checking addresses that could go toward actually serving clients or writing new policies.

None of this requires a catastrophe to bite. It just requires nobody in the agency having an easy way to see the whole book laid out geographically.

The fix: a monthly map of your book, not a one-time project

The way around this doesn't require GIS software, a mapping certification, or an analyst on staff. It requires turning your list of client addresses into a list of map coordinates — a simple column of latitude and longitude added next to each address — and then dropping that into a free mapping view to see where the dots cluster.

Once your addresses have coordinates, you can lay them over the flood maps, wildfire maps, or coastal zone maps you likely already have access to through your state insurance department or your carriers. You don't need enterprise software to draw a boundary and count the dots inside it. You need the coordinates, and a place to look at them next to a known risk map.

The part that used to require a GIS consultant — turning street addresses into coordinates, accurately, in bulk — is the part a subscription service does for you, every single month, for the price of a client dinner.

Step 1: Export your client list

Most agency management systems let you export your policyholder list to a spreadsheet — name, address, policy type, whatever fields you want. You're not changing anything about how you run your agency day to day. You're just pulling the list you already have.

Step 2: Upload the file

You upload that spreadsheet to your account. That's the entire technical step. No settings to configure, no software to install.

Step 3: Download your finished spreadsheet

Within a short wait, you get back the same spreadsheet, with a column added for each address's map coordinates. Everything else in your file — policy numbers, renewal dates, client names — stays exactly as it was.

Step 4: Drop the coordinates into a map view

Paste those coordinates into a free spreadsheet map feature or any simple online mapping tool. You'll see your entire book as dots on a map, instantly. Clusters are obvious the moment you look at it — you don't need training to spot a dense patch of pins along a coastline or inside a single county.

Step 5: Compare against known risk zones

Lay your dot map next to your state's flood zone map or a wildfire risk map from your carrier. You can now say, with confidence, exactly how much of your book sits inside a given zone — not a guess, an actual count.

Step 6: Repeat next month

Your book changes every renewal cycle. Run the same export and upload next month, and you have a fresh picture — not a project you did once and now treat as gospel two years later.

What it costs, in real numbers

This runs on the Starter plan, at $49 a month, which covers 50,000 US addresses. For context, that's far beyond what almost any independent agency needs in a month — most books run from a few hundred to a few thousand active policies, so you'd use a small fraction of that allowance even if you re-mapped your entire book every single month.

You can cancel anytime, and subscribing costs up to 30% less than paying per address each time you run a file. There's no annual contract, no setup fee, and no minimum commitment beyond the current month.

If your book is genuinely small — under a couple hundred clients — the Lite plan at $19 a month or the Plus plan at $29 a month may cover you comfortably instead. But most agents managing an active book with commercial lines, multiple carriers, or a producer or two on staff will find Starter the more comfortable fit.

Frequently Asked Questions

Is this hard to set up if I'm not techy at all? No. If you can attach a file to an email, you can use this. There's no software to install and nothing to configure beyond exporting your list and uploading it.

What happens if some of my addresses are messy or incomplete? Real client lists always have a few rough entries — a missing apartment number, an old rural route address, a typo from years ago. The system does its best to match what it can and flags anything it can't confidently place, so you know exactly which records need a second look instead of guessing which ones are wrong. If this comes up often, our guide on handling addresses that won't geocode walks through the common causes and fixes.

Can I cancel if I only need this for one renewal season? Yes. Plans are month to month, and you can cancel anytime without penalty. Many agents run it heavily during renewal review periods and lighter the rest of the year.

Is my client data safe? Your file is used to add coordinates and is not sold, shared, or used to build marketing lists. You're uploading an address list to get an address list back — nothing more happens to that data on our end.

Do I need to buy mapping software to see the results? No. The coordinates work in any free spreadsheet map feature or basic online mapping tool. You don't need a GIS license or any paid mapping software to visualize your book.

What if I have producers or a small team writing policies alongside me? That's common, and it doesn't change the workflow — you're still exporting one combined list and uploading one file. If your team eventually wants shared access across several people, our post on running geocoding for every client under one team plan covers how that works.

How often should I actually run this? Monthly is a sensible rhythm for most agents — often enough to catch a concentration trend building, not so often that it becomes busywork. Some agents tighten this up around renewal season and loosen it the rest of the year.
