ERP strategy, delivery, and care
ERP that performs as precisely as the business it runs.
Calder Holm partners with mid-market and enterprise operators on strategy, selection, implementation, and the years after go-live. Senior people stay in the room. The system is judged by outcomes, not by the size of the rollout.

94%
of programs go live on the date we commit — because the date follows the rehearsal, not the other way around.
Operators we have sat with
- Brant
- Merrow
- Halden
- Vesper
- Lark & Pine
- Northline
- Solace
- Keel & Co.
Platform fluency across SAP, Oracle, NetSuite, Microsoft Dynamics, and Infor. No license quota.
Practices
Seven ways in. One standard.
- 01Strategy & RoadmapA roadmap the board can hold: sequence, value, risk, and the work you will not do yet.
- 02ImplementationGo-live as a controlled Tuesday, not a heroic weekend.
- 03System SelectionA scored choice with a written record, free of license quotas.
- 04Customization & IntegrationConfigure first. Integrate cleanly. Customize only by written exception.
- 05Data MigrationTwo rehearsals, one cutover, numbers that agree.
- 06Support & Managed ServicesThe system keeps earning after the project team leaves.
- 07Training & ChangeAdoption designed with the process, not bolted on in week twelve.
The method
Sequence. Ordinary steps. An unusual standard.
We do not rename the work. We refuse to skip it. Orient, Choose, Shape, Land, Keep — and you may stop after any movement that has already given you the decision.
01
Orient
Six weeks, fixed
02
Choose
A decision, not a tour
03
Shape
Standard first
04
Land
A Tuesday
05
Keep
After the applause
Selected work
Numbers, not narratives alone.

Industries
Built around the operation, not a template.
- ManufacturingPlants, planning, and a close that does not argue with the floor.
- DistributionOrders, inventory, and a warehouse that tells the truth in the same hour.
- Professional ServicesProjects, people, and a margin you can see before the engagement ends.
- HealthcareSupply, finance, and operations that respect the clinical day.
- RetailStores, commerce, and inventory that can keep a promise across both.

“They refused to automate a process we were embarrassed by. That restraint is what made the dates believable.”
