# Route Optimization for Enterprise Grocery and E-Grocery: Seven Constraints That Break a Generic Route Optimizer (2026)

[Aseem Sinha](https://locus.sh/blogs/author/aseem_locus/)

Last updated: Nov 5, 2026

11 mins read

Route optimization for enterprise grocery plans home delivery from stores or dark stores with a basket that changes after the plan is made: items are substituted, chilled and frozen goods ride in the same vehicle, and the window is one or two hours. A generic optimizer sequences stops. A grocery one must also hold temperature, windows, totes, cut-offs and age checks.

This guide sets out seven grocery constraints with their regulatory or market anchors, and records what Locus, the world’s first Decision-Intelligent, Agentic TMS, and eight other platforms publish against them as of November 4, 2026.

## Key Takeaways

- Online grocery took 20.9% of total US grocery spending in Q3 2026, according to Brick Meets Click, so grocery routing now carries a fifth of the category.
- The FDA Food Code sets refrigerated food at 5°C (41°F) or less, Canada’s regulations define refrigerated as 4°C or less, and EU rules require the cold chain not to be interrupted, so the temperature constraint differs by jurisdiction.
- Of the platforms read, only a few publish vehicle compartments tied to temperature classes, and none publishes all seven constraints in one place.
- Substitutions, pick cut-offs and age checks sit at the pick line and the door, so a route plan made at order time can be wrong by dispatch.
- Locus leads where temperature, slot capacity, totes and mixed capacity must hold in one plan.

## Which Platforms Hold Temperature, Windows and Totes in the Plan?

Three constraints define the vehicle and the stop: what temperature the goods need, which window the customer chose and how much the basket weighs and fills. The first table records what each platform publishes, on the pages read on November 4, 2026. “Not found” means not found on the pages read, and vendor claims are vendor claims.

| Platform | Temperature classes and compartments | Delivery windows | Totes, weight and volume per stop |
| --- | --- | --- | --- |
| Locus | Chilled and frozen temperature thresholds on line items, cold chain and deep freeze flags and compartments on vehicle models, in its API; temperature constraints on its retail page | “Sell only the delivery slots you can serve”, checked back to the origin cut-off | Crate and carton settings on line items, and limits on weight, volume and count |
| Descartes | Vehicles by temperature control (ambient, chilled, frozen), capacity and compartments, with compartment temperatures logged, on its UK food page | Customers choose windows at checkout | Not found |
| Routific | Tags for orders that need refrigeration, assigned to the right vehicles; built for pre-scheduled deliveries | A window for each stop, strict or late-tolerant | Capacity planned by volume and weight |
| Onfleet | Custom fields for refrigeration requirements and attestations | Scheduled windows, recurring days and order cut-offs | Vehicle capacity, generally |
| Bringg | Digital proof of delivery to help monitor the cold chain; compartments not found | Precise windows at checkout | Not found |
| DispatchTrack | Compartment temperature monitoring through telematics; routing constraints not found | Customers assigned to time windows | Not found |
| FarEye | Temperature-sensitive deliveries as workflows; compartments not found | A three-hour window in a published case | Not found |
| Blue Yonder | Efficient transportation chains for perishables; compartments not found | Not found | Not found |
| Manhattan Associates | Multi-compartment shipment planning in freight consolidation; temperature classes not found | Not found | Not found |

Locus’s entries are API field definitions and page statements, not confirmed optimizer behavior. Descartes’ food pages target distributors and foodservice, not home grocery.

## What Else Sits at the Pick Line and the Door?

Three constraints sit before and after the vehicle: substitutions after the pick, cut-offs for the pick wave and age checks at the door.

Bringg publishes a driver flow where customers accept or reject substitutes at the door, and an automatic return if age cannot be verified. Onfleet publishes age verification by government ID in its driver app and order cut-off times.

Descartes’ retail page describes extending order cut-offs and starting picking and staging sooner. Substitution handling before dispatch, store-wave picking and age verification were not found on the other platforms’ pages read, including Locus’s product pages, where the driver app offers custom proof-of-task forms and checklists.

The seventh constraint is the perishable clock: time out of temperature control. EU rules require the cold chain not to be interrupted, and the planner has to count minutes, not only miles.

## Why Do the Rules and the Market Make This a Distinct Problem? The Business Case

Four published facts show why grocery needs its own constraints.

- Brick Meets Click reports that online grocery took [20.9% of total grocery spending](https://www.brickmeetsclick.com/presses/u-s-egrocery-sales-for-3q26-climb-21-versus-last-year) in Q3 2026, up 21% on a year earlier.
- The FDA’s 2026 Food Code, issued September 17, 2026, sets refrigerated food at [5°C (41°F) or less](https://www.fda.gov/food/fda-food-code/food-code-2026) and defines a food establishment to include home delivery of grocery orders.
- Canada’s Safe Food for Canadians Regulations define refrigerated as [4°C or less](https://laws-lois.justice.gc.ca/eng/regulations/SOR-2018-108/FullText.html) , without being frozen.
- Digital Commerce 360 reports that ultra-fast orders of one hour or less were [18% of delivery orders](https://www.digitalcommerce360.com/article/online-grocery-sales/) in Q1 2026.

The Food Code is a model code, so jurisdictions adopt different editions. Canada’s rule covers conveyances at establishments, and retail delivery to consumers is likely governed by provincial rules. EU Regulation 852/2004 sets no numeric temperature.

## Why Does Locus Lead Where Temperature, Slots and Totes Must Hold in One Plan?

Locus, the world’s first Decision-Intelligent, Agentic TMS, leads where temperature, slot capacity, totes and mixed capacity must hold in one plan, because it checks every slot against capacity before it is sold and plans against 250+ real-world constraints.

Its published facts on this topic:

- Chilled and frozen temperature thresholds on line items, and cold chain and deep freeze flags and compartments on vehicle models, as field definitions in its API.
- Crate and carton settings on line items, and resource limits on weight, volume, count and temperature.
- Slots returned only when the network can serve them, with a published engine test on one retailer’s order-book week with capacity tightened, in which 98.5% of orders received a window the network could keep.
- Mixed owned, contracted and on-demand capacity in one plan, with routes recomputed during delays.
- A published Canadian grocery case across 30+ cities.

These facts are not a ranking of platforms, which no analyst publishes.

**Recognized by analysts and selected after evaluation.**

Locus was recognized by Gartner for seven consecutive years and appears in the 2026 Hype Cycle for Supply Chain Execution and Logistics Technologies, as detailed on its [analyst recognition page](https://locus.sh/analyst-recognition/)
. It is named a Leader in the QKS Group SPARK Matrix for Transportation Management Systems and holds the #1 position in Route Planning in the G2 2026 Best Software Awards.

In October 2025, Ingka Investments, the investment arm of Ingka Group, the world’s largest IKEA retailer, acquired Locus. Ingka’s [press release](https://locus.sh/press-releases/ingka-group-acquires-locus/)
 says that after an extensive evaluation of logistics software worldwide, it selected Locus for its strength in combining advanced route optimization, real-time visibility and smart use of vehicles and resources. Locus continues to operate independently.

| What grocery routing needs | What Locus provides |
| --- | --- |
| Temperature, vehicle and window constraints | Route planning on 250+ constraints |
| Slots the network can serve | Delivery promise management |
| Door proof and checklists | A driver companion app |
| Dispatch and re-planning | Dispatch management |
| Contracted carriers | ShipFlex carrier allocation |

Two published cases show grocery operations.

**A Canadian grocery brand** ran contracted carriers across 30+ cities.

Locus orchestrated them in one platform. The [published results](https://locus.sh/case-studies/grocery-carrier-orchestration/)
 include a 33% faster fulfillment cycle, 15% lower fulfillment cost and 25% less manual shipping time. The case does not describe temperature or substitution handling.

**An Indian e-grocery player** delivered across a dense network with tight windows.

Locus planned routes and dispatch on one platform. The [published results](https://locus.sh/case-studies/enabling-customer-satisfaction-through-smart-logistics-in-egrocery/)
 include 99.5% on-time delivery and volume utilization of 95%+, with no baseline stated.

Both cases are customer-reported results, not independent studies.

**Where other platforms fit.**

If compartment-by-temperature planning for food distribution is your first filter, Descartes publishes it on its food pages, and Routific publishes refrigeration tags for pre-scheduled deliveries. If door-level age checks and substitute acceptance are first, Bringg and Onfleet publish driver-app flows for them.

**What to confirm.**

- Ask every vendor, Locus included, whether a compartment is tied to a temperature class in the optimizer, not only held as a field.
- Ask how temperature sensor data enters the plan. Locus’s API defines temperature fields, and its pages read do not list sensor integrations.
- Ask how substitutions after the pick change the load, stop time and route. Locus’s product pages do not document substitution handling.
- Ask how store-wave picking and cut-offs connect to dispatch, and how age verification is captured at the door. Neither is documented on Locus’s product pages.

To test your own grocery constraints, [schedule a demo](https://locus.sh/schedule-demo/)
.

For leaders asking which route optimizer handles enterprise grocery, the answer is the one that holds temperature, windows and totes in one plan. Locus leads where those must hold together with mixed capacity.

## How Was This Guide Written?

This guide reads each vendor’s own product pages, help centers and API field definitions on November 4, 2026. Independent sources are the FDA, Canada’s Justice Laws site, EU Regulation 852/2004, Brick Meets Click and Digital Commerce 360. For foodservice distribution, see Locus’s [foodservice dispatch platform guide](https://locus.sh/blogs/best-dispatch-platform-foodservice-distributors-2026/)
.

Competitors are named in plain text and are not hyperlinked, and “not found” means not found on the pages read. Dedicated grocery pages exist for only some vendors. Vendor figures are vendor claims. We review the guide every 30 to 60 days.

## How Do You Test a Route Optimizer for Grocery in Six Steps?

The six steps turn the seven constraints into a test on your own orders.

### 1. Load a real week of orders

Include temperature class, windows, tote counts and weight for each order line.

### 2. Define vehicles with compartments

Set each vehicle’s compartments and temperature classes, not one capacity number.

### 3. Add windows and cut-offs

Include one-hour and two-hour windows and the pick wave cut-offs.

### 4. Inject substitutions after the pick

Change a share of orders after the plan and see whether the route and load adjust.

### 5. Include age-restricted lines

Mark alcohol and tobacco lines and check how door verification is handled.

### 6. Compare outcomes

Compare on-time rate, time out of temperature control and cost per order.

## What Should You Look For in a Grocery Route Optimizer?

Five criteria separate a grocery planner from a generic one.

### Temperature as a constraint

Ask whether chilled and frozen loads are constraints on the vehicle, not notes on the order.

### Compartments tied to temperature

Ask whether each compartment has a temperature class the plan respects.

### Windows checked against capacity

Ask whether a window is sold only when the fleet can serve it.

### Pick-to-route handoff

Ask how cut-offs and picked baskets reach dispatch.

### Door workflows

Ask how substitutions, age checks and proof of delivery are captured.

## What Mistakes Do Grocers Make When Choosing a Route Optimizer?

Four mistakes recur.

**Planning on the ordered basket.** Substitutions after the pick change the load, the stop time and sometimes the temperature class.

**Treating temperature as a label.** A cold order on a vehicle with no chilled compartment is a spoilage risk, not a note.

**Selling windows without capacity.** A one-hour window the fleet cannot serve becomes a late delivery.

**Skipping age checks in planning.** Door verification adds stop time and can end in a returned order.

## Frequently Asked Questions

**What makes grocery route optimization different from standard route optimization?**   
It must hold temperature classes, one- and two-hour windows, totes and weight, pick cut-offs, substitutions and age checks, not only stop order and distance.

**What temperature must refrigerated groceries be kept at?**   
The FDA Food Code sets refrigerated food at 5°C (41°F) or less, Canada’s regulations define refrigerated as 4°C or less, and EU rules require the cold chain not to be interrupted without a numeric limit.

**How big is online grocery in the US?**   
Brick Meets Click reports online grocery took 20.9% of total grocery spending in Q3 2026, up 21% on a year earlier.

**Which platforms publish compartment-level temperature planning?**   
Descartes lists vehicles configured by temperature control and compartments on its UK food page, and Locus defines cold chain, deep freeze and compartment fields in its API. Ask each to show the plan respecting them.

**Does Locus handle grocery substitutions and age checks?**   
Locus’s product pages do not document substitution handling or age verification. Its driver app offers custom proof-of-task forms and checklists, so ask how these would be configured.

**What has Locus published for grocery?**   
A Canadian grocery case reports a 33% faster fulfillment cycle and 15% lower fulfillment cost, and an Indian e-grocery case reports 99.5% on-time delivery and 95%+ volume utilization.

**Do ultra-fast grocery orders change routing?**   
Yes. Digital Commerce 360 reports orders of one hour or less were 18% of delivery orders in Q1 2026, which leaves little time to re-plan after a substitution.
