STACK PATTERN
Kerridge K8 is the ERP and system of record: items, customers, sales orders, inventory, financial close. eLogii is the routing and field execution layer that turns K8 sales orders into optimized routes, live ETAs, driver workflows and proof of delivery, then writes the completion data back. Two systems, two jobs. The integration runs over K8 REST API on the K8 side and eLogii’s REST API on the other, typically delivered in 3 to 5 weeks alongside the eLogii rollout.
TRUSTED BY HUNDREDS OF HAPPY CUSTOMERS
K8 and eLogii sit in different layers of the same stack. K8 is the ERP: items, customers, sales orders, inventory, financial close, multi-subsidiary reporting. eLogii is the routing and field execution layer: the route plan, the driver app, the live ETAs, the proof of delivery, the customer-facing tracking. Both products expose mature REST APIs, and the integration between them is a normal piece of K8-side work.
In the combined pattern, K8 stays the system of record for items, customers, orders, inventory and financial close. Sales orders flow from K8 into eLogii as routable tasks; eLogii optimizes against vehicles, depots, time windows, capacities, skills and SLAs; the driver app captures POD, photos, signatures and any custom forms; completion writes back to K8 so AR can invoice and inventory can clear. The integration runs over both products’ REST APIs.
Three tables: where ERP and business data live (K8 leads), where routing and field execution live (eLogii leads), and what the integration architecture looks like on both sides.
| K8 | eLogii | |
|---|---|---|
| Item master / SKU catalog | Core. Item record, BOMs, lots, serials, pricing | Not in scope. Looks up items by external_id from the integration |
| Customer master, AR / AP | Core. Customer record, billing address, payment terms, AR/AP | Not in scope. Customer delivery info flows in via integration |
| Sales orders, invoices, GL | Core. Order capture, fulfilment, invoicing, multi-subsidiary close | Not in scope |
| Inventory levels, demand planning | Core. K8 demand planning covers forecasting and replenishment | Not in scope |
| Item weight, cube, handling for capacity math | Item record fields | Reads via integration to feed optimizer constraints |
| Customer delivery address, time windows | Customer + sales order record fields | Reads via integration to feed optimizer constraints |
| Multi-subsidiary, multi-currency, financial close | Core. K8 multi-branch and multi-company posting | Not in scope |
| eLogii | K8 native | |
|---|---|---|
| Multi-stop route optimization with constraints | Two engines, six configurable modes; vehicles, depots, capacities, time windows, skills, SLAs | K8 warehouse picks and shipments sequences stops within a wave; not a constraint-aware route optimizer |
| Multi-day, long-haul, multi-depot routing | Plan a single day or an entire month in one run; multi-depot, multi-day, overnight stops | Not in scope |
| Driver mobile app for on-road execution | Native iOS and Android: navigation, POD, photos, signatures, conditional outcomes, custom forms | K8 warehouse management and K8 mobile companion cover warehouse and HR; no on-road driver workflow |
| Live GPS, route ETAs, branded customer tracking | Live driver GPS stream, route ETA updates, multi-brand tracking pages with embedded content | Not in scope. K8 storefront / customer portal shows shipment status, not live ETAs |
| Slot booking co-pilot – route-aware availability | Returns only delivery slots that fit the current optimized plan; ~35% fewer failed visits | Not in scope |
| Customer self-reschedule on route-aware slots | ~70% of reschedule requests handled without coordinator involvement | Not in scope |
| Configurable POD forms and conditional outcomes | Configurable POD with photos, signatures, conditional steps, custom fields, custom forms | Not in scope |
| Parcel carrier rate-shop and label-print | Not in scope. Own-fleet routing only | Shipping integration covers UPS, FedEx, DHL, USPS rate-shop and labels |
| K8 | eLogii | |
|---|---|---|
| API style | K8 REST API, SOAP services and EDI for server-side logic | REST, JSON over SSL, ApiKey auth, predictable resource URLs |
| Authentication | OAuth 2.0, OAuth 2.0 or API key, depending on K8 version, or M2M | ApiKey header, generated in Dashboard > Configuration > API Keys |
| Sandbox environment | K8 test environments accounts for development and testing | Full API parity at api-sandbox.elogii.com |
| Bulk operations | Async record queries, K8 batch processing for high-volume batches | createOrUpdateMany endpoints handle hundreds of tasks per call |
| Webhooks / events | K8 trigger or workflow hook scripts + outbound REST events for outbound events | Seven event types including Driver/Task Tracking Update with live GPS stream |
| Optimization callable via API | No route optimization engine in core K8 | All six modes callable via REST; lock specific routes, manually reorder stops |

End to end, how a delivery order moves from K8 to a completed POD and back into K8 for invoicing and inventory. The exact wiring depends on your tenant and the integration platform your team uses, but the shape is the same in every deployment.
POST /tasks/createOrUpdateMany, with the K8 record ID held as external_id so every eLogii object can be traced back to its K8 source record.Variations on the same pattern: multi-depot picking where K8 branches and warehouses drive depot selection; multi-day jobs for field service where the eLogii task represents the visit and the K8 project represents the engagement; customer cancellations from K8 triggering eLogii re-optimization. None of these require special connector logic; they are normal mappings across two REST APIs.
K8 is a deep ERP and ships modules that touch the delivery problem, but none of them are route optimization. Drawing the line clearly matters when you are scoping eLogii alongside K8:
This is not a criticism. K8 is an ERP and was never built to be a routing layer. The point is to be precise about where its features stop, so the integration with eLogii has a clean seam.
We’d never go back to the way we were planning before. eLogii is the backbone as well as the brain of our planning operations, translating actively to our bottom line.

Three shapes cover almost every K8 + eLogii deployment. The right one depends on what your K8 team already has in place and which side of the seam you want the orchestration logic to live on.
api-sandbox.elogii.com and publicly documented endpoints.K8 is a distribution ERP and that’s where the combined pattern lives.
Wholesale food and drink, building materials, bathroom and kitchen, plumbing and heating, electrical wholesale, automotive aftermarket. K8 owns items, lots, batches, expiry, pricing, customer master, delivery addresses, sales orders, inventory and financial close. eLogii owns the route plan across the fleet, vehicle and capacity and time-window optimization, the driver mobile app for POD and pallet-level signing, the live customer tracking, and the slot booking on the storefront. Typical reach is own-fleet distribution operations with 50+ in the field, multi-depot picking and routing, and recurring weekly or monthly delivery patterns. Outcome shape from current eLogii customers in distribution: Brymec lifted productivity 30% and routing efficiency 20%; ATS Building Products improved deliveries per route by ~98%; Porcelanosa runs 95%+ ETA accuracy on daily distribution.
eLogii runs alongside K8; nothing changes on the K8 side. eLogii pricing starts from $3,000 per month as a platform fee, banded by field staff, drivers, jobs per day and the modules required. Each band includes a quota; cost steps up when the operation crosses a band, not when you add an individual seat. Customers typically report 3 to 4× return on investment within 6 months, and combined K8 + eLogii rollouts (including the integration) complete in 3 to 5 weeks. K8 pricing is its own thing and is not affected by adding eLogii.

We have been extremely impressed with the results from eLogii so far. The solution is powerful and the team have found it extremely intuitive and easy to get going with. We signed a multi-year agreement with eLogii and are looking forward to deepening our relationship with them over the next years.

Three steps for teams whose delivery or field execution problem has outgrown what K8’s built-in workflow covers, and who want to keep K8 for items, customers, orders, inventory and financial close while adding eLogii for routing and execution on top.
Item master, customer addresses, sales orders, depots (K8 branches and warehouses) and vehicles inventoried. K8 REST API queries return the open delivery book; mapping to eLogii task fields documented end to end. Custom K8 fields surfaced as eLogii custom fields. Sandbox connectivity proved out on both sides before any production data moves.
Weeks 1–2Custom data simulation against your historical K8 delivery book so you can validate the modeling and project savings before go-live. Side by side: what your planners produce today vs. what eLogii produces with the same orders. Approve the optimizer settings and the write-back fields.
Weeks 2–3Start with one business unit, depot or region. Drivers onboarded onto the eLogii app. Webhook stream wired to your integration layer. POD and completion data writing back to K8 for AR and inventory. Expand to the rest of the operation once the first cohort is steady. Most teams complete the transition in 3 to 5 weeks total.
Weeks 3–5Unimasters runs eLogii across a multi-country operation and achieved 50% less planning time and 49% fewer service calls. Multi-country rollouts deploy in weeks, not quarters.
Each of these takes one place where eLogii adds depth alongside K8, walks what K8 handles today, what the capability actually needs, where users land without it, how eLogii covers it, and how it writes back to K8 via K8 REST API.
K8 has no native constraint-aware route optimizer. eLogii is the routing layer on top: two engines, six modes, REST-callable, plugs into K8 API.
K8 warehouse mobile app is warehouse-side. eLogii ships a native iOS / Android driver app with offline POD, photos, signatures, conditional steps and custom forms.
shipment confirmation record can hold notes and attachments. eLogii captures POD on the driver app: photos, e-signatures, conditional outcomes, custom forms, with REST write-back to K8.
K8 storefront / customer portal shows shipment status. eLogii streams live driver GPS, real-time route ETAs and branded multi-brand customer tracking pages on top.
K8’s date picker doesn’t check whether a date is achievable. eLogii’s slot booking co-pilot returns only slots that fit the optimized plan. ~35% fewer failed visits.
Through both products’ REST APIs. K8 exposes K8 REST API plus K8 customization layer, K8 REST endpoints and a outbound REST events for outbound events; eLogii’s REST API has 70+ endpoints, ApiKey auth, a full-parity sandbox at api-sandbox.elogii.com and seven webhook event types including Driver/Task Tracking Update with live GPS. Typical pattern: open delivery orders flow from K8 to eLogii (pulled on a schedule or pushed via a K8 trigger or workflow hook on order approval); eLogii runs the optimization and dispatches the driver app; completion data writes back to K8 for AR invoicing and inventory clearance. Most deployments are delivered in 3 to 5 weeks alongside the eLogii rollout.
No. K8 warehouse management are warehouse-floor workflow: wave management, picking strategies, packing stations, shipment confirmation. They sit upstream of routing. eLogii is on the road: the route the truck takes once the load is built, the order each stop runs in, the driver app, the ETAs and the customer-facing tracking. If you already run K8 warehouse management, eLogii starts where the WMS hands off.
No. K8’s carrier/parcel integration is rate-shop and label-print for parcel carriers (UPS, FedEx, DHL, USPS). It is for parcel handoff. eLogii is for own-fleet routing: your trucks, your drivers, your stops. If your delivery is all parcel through carriers, eLogii is not the right tool. If you run an own fleet for distribution or field service, eLogii is the layer K8 was never built to be.
Typically: open sales orders or delivery orders, the customer’s delivery address and geo, line items with weight and cube from the item record, any delivery time window, special-handling flags, the assigned depot or K8 Location, and any custom fields your operation depends on (access notes, gate codes, key handling). All of that is exposed via K8 REST API today. The integration job either pulls on a schedule or pushes via a K8 trigger or workflow hook on order approval.
Typically: delivery confirmation (delivered, refused, partial, failed and the reason), proof-of-delivery references (photo IDs, signature image references), timestamps (arrival, completion), driver-collected cash or payments where applicable, any custom form data captured in the driver app, and the final delivery status that triggers AR invoicing and inventory clearance. The write-back uses K8 REST API or K8 REST endpoint endpoints from your integration layer.
Yes. eLogii has REST + JSON APIs, a sandbox at api-sandbox.elogii.com and publicly documented endpoints. Whichever iPaaS your team already uses can broker eLogii alongside K8.
Typically 3 to 5 weeks from kickoff to a phased go-live, including the K8 integration. Most teams start with one business unit, depot or region, validate against historical K8 delivery data, then expand. Heatleys evaluated 20 platforms and went live fast on eLogii, citing how quickly drivers could be onboarded.
It does not. K8 pricing stays as-is, eLogii is added on top. eLogii pricing is a platform fee, banded by field staff, drivers, jobs per day and modules, from $3,000 per month. Customers typically report 3 to 4× return on investment within 6 months on eLogii.
Yes. eLogii runs operations at scale: J-Club (9,000+ stores), NHS, Belfast City Council, Vergo, Bristow & Sutor, Porcelanosa, Caldic and Berkmann Wine Cellars. ISO 27001 and SOC 2 Type 2 certified.
