Invoice clients for ERP implementation, system configuration, and data migration projects. Professional invoices from Tidybill.
An ERP consultant invoice covers work implementing, customising, and optimising Enterprise Resource Planning systems such as SAP, Oracle NetSuite, Microsoft Dynamics, or Odoo. ERP projects are among the most complex and expensive in enterprise software, involving business process analysis, system configuration, data migration, user training, and change management. ERP consultants may specialise in a specific platform or module (finance, supply chain, HR, manufacturing) and are typically hired by businesses undergoing digital transformation or replacing legacy systems. Because ERP projects often involve large teams and long timelines, invoices should clearly reference the project phase, workstream, and consultant's role. Day rate billing is standard for ERP consultancy, with some firms offering fixed-price phases for well-scoped activities like training or data migration.
| Service | Typical Rate | Unit |
|---|---|---|
| ERP consulting (day rate - senior) | 900 | day |
| ERP consulting (day rate - mid-level) | 650 | day |
| Business process analysis and documentation | 1500 | workstream |
| Data migration design and execution | 5000 | phase |
| End user training (per day) | 1200 | day |
| Post go-live hypercare support (weekly) | 800 | week |
Invoice weekly or bi-weekly for embedded roles with a timesheet showing days, activities, and workstreams covered. For fixed-price phases, invoice on milestone completion with a sign-off from the project manager. Always reference the project name, phase, and your role on the invoice. Attach timesheets for any time-and-materials work. Travel and subsistence should be invoiced as reimbursable expenses with receipts attached.
