1. Scope and governance

Written business case with goals and measurable success criteriaCRITICALNamed executive sponsor and a business project ownerCRITICALSteering committee with fixed meeting cadenceScope document listing included modules, sites, legal entities and languagesCRITICALChange request process agreed with the implementation partnerKey users named with their project time agreed by line managersCRITICALFixed price versus time and material split understood and approved

2. Process design and fit gap

Current process maps for order to cash, procure to pay and plan to produceCRITICALFit gap list reviewed by key users, each gap marked standard, configure or customCRITICALEvery custom development has a business justification and an ownerCRITICALCosting method decided (standard, average, actual) and agreed with financeCRITICALProduction planning approach defined for each product familyQuality and traceability requirements (batch, serial, certificates) capturedAuthorization concept drafted with segregation of duties

3. Data and migration

Migration scope defined: master data, open items, open orders, historyCRITICALArticle, customer and supplier cleansing completed before loadCRITICALBills of material and routings validated by engineeringCRITICALOpening balances reconciled with the general ledgerCRITICALAt least two full migration rehearsals completed with sign offCRITICALArchive plan for historic data that will not migrateUnit of measure and numbering conventions agreed

4. Interfaces and localization

Interface inventory with owner, direction, format and frequencyCRITICALBanking formats such as SEPA files tested with the house bankCRITICALAccounting export tested with your tax advisor, for example a DATEV exportE-invoice formats for your customers tested (for example XRechnung or ZUGFeRD)VAT, Intrastat and recapitulative statements verified for each countryCRITICALEDI partners notified with test windows scheduled

5. Testing, training and go live

Test cases written from real business scenarios, not menu walkthroughsCRITICALIntegration test covering a full order through shipment, invoice and paymentCRITICALUser acceptance sign off recorded by key usersCRITICALEnd user training completed before cutover, with role based materialCRITICALCutover plan with timeline, responsibilities and a rollback decision pointCRITICALInventory count frozen and reconciled before final loadCRITICALHypercare roster covering at least the first month-end closePost go live review with lessons learned and a backlog for phase two

Tick items as they are completed. Any unticked critical item on the go live day should be an explicit, signed risk acceptance.

Migration data pre-check

We can run an AI assisted review of your extracted master data for duplicates and inconsistencies before the first rehearsal. Optional.

Optional. The tool and every export work without this. No spam.

How to use this checklist

Work through the groups in order, but start data cleansing early because it is the item most often underestimated. Assign each item an owner and a date when you export the checklist to Excel. Critical items are flagged because skipping them is the most common cause of delayed go lives. Review the list in every steering committee until all critical items are closed or consciously accepted.

Scope and process design

Fit gap analysis is where budgets are won or lost. Every custom requirement should be challenged: does the standard process cover 80 percent of the need, and can the business adapt for the rest? Record the decision and the person who made it. Custom development adds upgrade cost for years, so treat it as an investment with an owner, not a favour to a department.

Compare current and target process maps side by side
Rank gaps by business impact, not by who asked loudest
Agree the costing method before configuring inventory
Plan authorizations early, not in the final weeks

Data, interfaces and testing

Plan at least two migration rehearsals and reconcile each against the ledger and the physical stock. Interfaces to banks, tax advisors, customers and shop floor systems should be tested end to end with real files. Test cases should follow real scenarios such as a make to order job with a purchased component, from quote to payment, because that is where integration defects appear.

Go live and hypercare

Choose the cutover date to avoid quarter end and inventory peaks. Define the rollback decision point in advance, and make sure the person who can say no is available. Hypercare should cover at least the first month-end close because that is when finance, inventory valuation and reporting issues surface. Keep a visible issue list and review it daily during the first weeks.

Frequently Asked Questions

Is this checklist from proALPHA?

No. It is an independent, general purpose checklist for mid-market ERP implementations, written with proALPHA style projects in mind. Follow your implementation partner's methodology where it differs and use this list as a cross check.

How long does a proALPHA implementation take?

Timelines vary with scope, number of sites and customization. Many mid-market projects run from several months to well over a year. Data readiness and user availability usually set the pace more than software setup.

What is the biggest risk in an ERP implementation?

Scope growth and poor data are the usual culprits, followed by key users who are not given time for the project. A strong sponsor and a firm change process address most of these.

Do I need to migrate all history?

Rarely. Most companies migrate master data, open items and open orders, and keep older history in an archive or reporting database. Decide with finance and your auditor what retention rules require.

If you want help turning this into a project plan, or want AI assisted checks on your migration data before the rehearsals, Netray can support that alongside your implementation partner.
