Letter of Clarification and FAQ’s
We are excited to announce that, effective August 31, 2026, MacAllister Machinery Company (“MacAllister”) will transition to a single Enterprise Resource Planning (ERP) system.
Following MacAllister’s acquisition of Michigan CAT in 2011 and the brand’s integration in June 2025, this move to one unified system marks the next step in our journey.
This transition is more than a system upgrade—it represents meaningful progress in how we collaborate and operate as one company.
While we have spent countless hours working toward this day to minimize the impact to you, our valuable customer, we want you to be aware of this change and how it may impact you.
☐ Vendor Update – You will see MacAllister branding on invoices, statements, and agreements. You should expect to update remittance information located on your new invoices. Purchase Orders generated after August 31, 2026, should reflect MacAllister. Please note, MacAllister will never ask you to update banking information or remittance details via individual email or phone.
☐ Account Number – Most account numbers will remain the same. For those customers affected by an account number change, you will receive communication regarding your updated account number.
☐ BillTrust Enrollment – Customers enrolled in BillTrust may experience temporary maintenance from September 1, 2026, to September 8, 2026. If you experience this, please contact us directly for invoice copies or to make a payment.
If you have any further questions not contained in this communication, please contact us at moc.retsillacamnull@noitargim and we will be happy to address your question.
