To balance delivery routes across drivers in Google Sheets, use the InstaMaps add-on. Apply the =TERRITORY(A2:A50, 5) formula to automatically group your stops into 5 balanced geographic zones, then use =VISIT_ORDER() to sequence the stops within each specific driver's territory, eliminating manual adjustments.
This workflow is built for local delivery dispatchers, field service managers, and small fleet owners currently frustrated by unequal route distribution in apps like Circuit. The end state is a fully automated spreadsheet where every driver receives an equal share of stops, sequenced for minimum drive time, and viewable on a live map.

How do I balance delivery routes across drivers?
To balance delivery routes across drivers without manually dragging pins on a screen, use a two-step deterministic approach in Google Sheets. As one Circuit reviewer pointed out, relying on a routing app's automatic suggestions can create operational problems: "Routes aren't always equally distributed between the drivers. Sometimes I have to manually adjust." Algorithmic routing apps often group stops based purely on the shortest overall distance, entirely ignoring the human element of workload fairness.
This black-box approach frequently leaves one driver with 40 stops clustered tightly in a high-density city center, while another driver gets 12 stops spread across distant suburbs. Dispatchers are then forced to spend time manually overriding the software to balance the daily workload.
InstaMaps replaces this guesswork with a transparent, math-based spreadsheet workflow. First, you use the =TERRITORY() function to divide your raw list of coordinates into a specific number of geographic zones. If you have 100 stops and 4 available drivers, the formula mathematically splits the map into four distinct, non-overlapping areas, ensuring each driver receives exactly 25 stops.
Second, you apply the =VISIT_ORDER() function to sequence the stops inside each specific territory into a logical, drivable route. Once calculated, you use =INSTAMAP() to generate a live, hosted map URL that visually confirms the loads are balanced and color-coded by driver. You avoid manual adjustments entirely because adding or removing a driver simply requires updating a cell reference, prompting the formulas to recalculate the boundaries instantly.
How do you assign stops evenly in Google Sheets?
Assigning stops evenly requires mapping your locations to specific geographic zones before sequencing them for driving directions. By using the InstaMaps add-on, you can calculate these boundaries directly inside your spreadsheet without manual measurement tools.
1. Prepare your address data: Ensure every destination is in a single column, such as A2:A151 for 150 stops.
2. Geocode the stops: Convert those text addresses into latitude and longitude coordinates. In column B, use =GEOCODE(A2:A151). This provides the precise spatial data required for territory mapping.
3. Define your driver list: Create a separate column representing your active drivers for the day. For four drivers, list their names in cells G2:G5 (e.g., Driver A, Driver B, Driver C, Driver D).
4. Assign balanced territories: In column C, apply the territory formula: =TERRITORY(B2:B151, G2:G5). This function analyzes the coordinates in B2:B151 and assigns each stop to a driver from your G2:G5 list, drawing logical geographic boundaries to ensure the workload is distributed evenly by location.
5. Sequence the stops: Now that column C dictates which driver handles which stop, calculate the optimal sequence for each route. In column D, enter =VISIT_ORDER(B2:B151, C2:C151). This outputs a number (1, 2, 3...) for each driver's stops, minimizing backtracking.
6. Generate navigation links: To send these routes to your drivers' phones, use =ROUTE_LINK(B2:B151, D2:D151) in column E. This creates a Google Maps URL for turn-by-turn directions (note: this specific function supports a maximum of 11 stops per link).
7. Map the routes: Perform a visual check by using =INSTAMAP(B2:B151, C2:C151, D2:D151) in a blank cell. This returns a live map URL that plots the stops, color-coded by driver and numbered by the exact visit sequence. If a new order is added to row 152, the map URL automatically updates.
Balancing 150 stops across 4 drivers: A worked example
Consider a local delivery business handling 150 stops on a Friday. The dispatcher has addresses in A2:A151 and four available drivers: Mark, Sara, Jen, and Tom (listed in G2:G5).
The dispatcher runs =GEOCODE(A2:A151) in column B to get the exact coordinates for all 150 locations. Next, they run =TERRITORY(B2:B151, G2:G5) in column C. The add-on draws invisible polygon boundaries across the city map based on those coordinates. It assigns exactly 37 or 38 stops to each driver, creating four balanced zones instead of leaving the distribution to chance.
To sequence these stops efficiently, the dispatcher runs =VISIT_ORDER(B2:B151, C2:C151) in column D. This outputs a specific sequence number (1 through 38) for each driver's assigned territory, ensuring they drive in a logical line rather than zigzagging across town.
Finally, the dispatcher runs =INSTAMAP(B2:B151, C2:C151, D2:D151) in cell F2. This generates a live map URL. When the dispatcher clicks the link, they see four distinct color-coded lines, showing Mark's 37 stops numbered 1 to 37, and Sara's 38 stops numbered 1 to 38.
Edge case: What happens if Tom calls out sick at 8:00 AM? In a standard routing app, the dispatcher would have to manually select Tom's stops and reassign them to the remaining three drivers, completely derailing the morning schedule.
In Google Sheets using InstaMaps, the dispatcher simply deletes Tom's name from cell G5, leaving G2:G4 (Mark, Sara, and Jen). Because the =TERRITORY() formula actively references the range G2:G5, the sheet instantly recalculates the 150 stops into three even territories of 50 stops each. The =VISIT_ORDER() updates the sequencing automatically, and the hosted map URL generated by =INSTAMAP() reflects the new three-driver distribution without any further manual data entry. (Note: The free tier covers 100 lookups per day, but registering a free email unlock raises this limit to 1,000 lookups per day, easily covering this 150-stop batch).
Circuit vs. InstaMaps for delivery route balancing
When evaluating how to balance delivery routes, the core difference between dedicated routing apps and spreadsheet add-ons lies in how routes are constructed and how they are priced.
Circuit is a dedicated, algorithmic routing application. As one user pointed out in a review, its algorithm sometimes struggles with workload density: "Routes aren't always equally distributed between the drivers. Sometimes I have to manually adjust." When an app's proprietary algorithm prioritizes the absolute shortest overall path or fewest miles driven rather than driver fairness, it routinely fails to balance the human workload. It might give one driver 45 stops in a dense urban center and another driver 10 stops in the distant suburbs, forcing the dispatcher to waste time dragging and dropping stops on a screen. Furthermore, Circuit and similar apps operate on a recurring monthly or annual subscription model, charging per vehicle or per dispatcher seat.
InstaMaps is a free Google Sheets add-on that uses deterministic spatial logic. Instead of a black-box algorithm guessing the optimal path, you control the exact parameters. If you use =TERRITORY(B2:B150, G2:G5) to split coordinates across four drivers, the add-on mathematically divides the geographic area into four balanced zones based on the data you provide. You then rely on =VISIT_ORDER() to sequence those stops logically.
To dispatch the routes to your drivers' phones, you can use =ROUTE_LINK() to push up to 11 stops at a time directly into the official Google Maps URL scheme for turn-by-turn navigation.
Because InstaMaps lives entirely within Google Sheets, your routing data integrates directly with your existing order data, customer CRM exports, or inventory counts. There are no monthly subscription fees. The add-on is entirely free, and the generous free tier allows 100 lookups per day (up to 1,000/day with a free email unlock), which easily covers small fleet daily routing without software lock-in.
Can Google Sheets create a live map for each driver?
Yes. After assigning stops with =TERRITORY(A2:A50, B2:B50, 3) and sorting them with =VISIT_ORDER(A2:A15, B2:B15), dispatchers can generate a live, shareable map for each driver using =INSTAMAP().
If Driver A’s optimized stops are in rows 2 through 18, populate the target cell with =INSTAMAP(G2:G18, H2:H18). The function immediately returns a hosted URL. Dispatchers send this specific URL to the driver's phone.
When a customer calls to cancel an appointment, the dispatcher simply deletes that row in Google Sheets. The hosted map automatically reflects that change the next time the driver refreshes the link. There is no need to export new PDF files, regenerate static maps, or email updated CSV attachments.
If you prefer direct point-to-point navigation rather than a hosted map overlay, use the =ROUTE_LINK() function. Because this relies on Google Maps' official URL scheme, it is capped at a maximum of 11 stops. For drivers running a 47-stop route across a 200-home territory, =INSTAMAP() is the reliable method to visualize the full daily workload, while =ROUTE_LINK() works best for shorter, multi-stop sprints.
Limits and honest alternatives for route balancing
InstaMaps is a free Google Sheets add-on. The free tier allows for 100 lookups per day. If you verify your email through the add-on interface, this limit increases to 1,000 lookups per day at no cost. If you are processing a 500-row list and running =VISIT_ORDER() alongside =TERRITORY() and =DISTANCE(), you will exhaust these daily lookups quickly.
Processing time is another constraint. Google Sheets computes custom functions sequentially. If you pass a large dataset into =VISIT_ORDER(), the sheet may take several minutes to calculate the optimal sequence. You will see a "Loading..." status in the cells until the operation finishes.
When should you use a standalone routing application instead? Dedicated routing software is a better fit if your routing requires strict time-window constraints (e.g., customer A must be visited between 9:00 AM and 10:00 AM), specific vehicle capacity tracking, or dynamic real-time traffic avoidance.
InstaMaps handles geographic clustering and basic proximity optimization based on driving distances. It does not factor in live traffic accidents, driver shift maximums, or payload weight limits. If your business requires balancing 50 drivers across a major metro area with hard delivery SLAs, a paid enterprise tool is the correct choice. For a local team managing standard daily delivery zones, spreadsheet routing provides the necessary math without a monthly subscription.
Who is this Google Sheets route balancing workflow for?
This workflow is ideal for local delivery dispatchers, field service managers, and small business owners who already track their logistics in Google Sheets. If you manage a small team of 2 to 5 drivers, and each driver handles 5 to 50 stops a day, InstaMaps provides the exact tools to divide the work fairly without paying for a dedicated routing platform.
If your current process involves manually cutting and pasting addresses from an exported CSV into Google Maps, or manually drawing city boundaries to decide which stops go to which driver, this add-on solves that specific bottleneck.
Teams managing specific local deployments-such as a 5-crew farm equipment servicing route, a local bakery delivering to 47 cafes, or a real estate photographer covering a localized metro area-will find the =TERRITORY() and =VISIT_ORDER() functions directly address the problem of uneven workloads.
It is built for the dispatcher who needs a quick, mathematically sound way to split a list and hand a live link to a driver. It is not built for operations managers overseeing a national carrier fleet requiring API-level telematics integration.

Common Questions
You can automatically split addresses by using the =TERRITORY() custom function in Google Sheets. If you have 100 stops in cells A2:A101 and 5 drivers, typing =TERRITORY(A2:A101, 5) assigns a territory number from 1 to 5 to each address based on geographic proximity. Next, filter your sheet by each territory number and assign those rows to individual drivers. This ensures stops are clustered geographically rather than randomly assigned.
The =TERRITORY() formula is an InstaMaps custom function that groups geographic coordinates into a specified number of balanced, non-overlapping zones. For example, =TERRITORY(GEOCODE(A2:A100), 4) takes your addresses, converts them to coordinates, and divides them into four distinct regions. It calculates the optimal boundaries based on spatial distribution rather than just splitting a list alphabetically or sequentially. You use it when you need to divide a large pool of stops among a specific number of technicians or drivers.
Native Google Sheets does not have a built-in route optimizer, but you can add this capability by installing the free InstaMaps add-on. Once installed, the =VISIT_ORDER() function analyzes a list of addresses and outputs the most efficient sequence to visit them. You can use this alongside =DISTANCE_MATRIX() to estimate drive times between the optimized stops. Sheets simply acts as the database while the add-on handles the routing calculations.
InstaMaps is a direct, free alternative for users who find route planning software too rigid or experience issues like poorly balanced loads. Unlike Circuit, which requires a monthly subscription for multiple drivers and high stop counts, InstaMaps operates entirely within Google Sheets and provides 100 free daily lookups, or 1,000 per day if you verify your email. While it lacks GPS tracking from a mobile app, you can generate shareable tracking links using =TRACKING_LINKS(). If you specifically need to fix unbalanced routes, using a spreadsheet offers far more manual control over territory division.
The base free tier allows for 100 lookups per day, which resets every 24 hours. Verifying your email address at no cost permanently increases this limit to 1,000 lookups per day. A single geocoding operation or route optimization sequence counts against this quota, so processing a 50-stop route using =VISIT_ORDER() will consume 50 lookups. If you exceed the daily limit, the formulas pause until the reset rather than charging you automatically.
To create a shareable map, use the =INSTAMAP() formula in any blank cell, referencing the location data you want to plot. For example, =INSTAMAP(B2:B50, C2:C50) generates a live, hosted URL that displays your stops as pins on an interactive map. The map updates automatically whenever you change, add, or delete data within those referenced cells. You can paste this URL into an email or text message to share the live route with your drivers.
