Most failed ERP projects were not lost during implementation. They were lost during selection, months before anyone configured a single form. The requirements were vague, the demos were theater, the scoring rewarded the best salesperson instead of the best fit, and the contract left every hard question for later. By the time the project struggled, the root cause was already a year old.
ERP RFP consulting exists to prevent exactly that. Here is what it involves, why it pays for itself, and how to know whether you need it.
Why ERP RFPs Go Wrong (4 Common Failures)
The classic failure pattern looks like this:
- The requirements list is a wish list. A team assembles requirements by asking each department what they want, which produces hundreds of line items mixing genuine differentiators with features every modern ERP has. Vendors check nearly every box, because at the RFP stage everything is technically possible.
- Demos get scripted around vendor strengths. A polished demo of the vendor’s best flow tells you nothing about your hardest flow. Scoring gets dominated by demo impressions and presenter skill.
- Software and partner are evaluated as one bundled decision. The software might be right while the proposed implementation partner is wrong for your industry, your size, or your geography. Evaluating them together hides that.
- Total cost stops at year one. Licensing, ISVs, integrations, internal staffing, update management, and ongoing support over five years rarely make it into the comparison, which is how the cheapest proposal becomes the most expensive system.
What ERP RFP Consulting Actually Includes
A good RFP consultant runs the selection as a structured project. The core workstreams:
- Requirements that focus on differentiators. Instead of a 600-line checklist, the work is identifying the 40 to 80 requirements that actually separate systems for your business: your costing method, your warehouse processes, your revenue recognition, your intercompany structure, your regulatory obligations.
- Realistic process scenarios for demos. Vendors demo your scenarios with your sample data instead of their polished script. Watching a system work through your actual order-to-cash flow, including the ugly exceptions, is worth more than any feature matrix.
- Separate scoring for software fit and partner fit. References get checked for both, and the implementation team proposed in the SOW gets evaluated, not just the firm’s logo slide.
- Honest total cost of ownership modeling. Licensing (including compliance exposure), implementation, ISVs, integrations, internal staffing, and ongoing support and update management across five years.
- Contract and SOW review before signature. Assumptions, out-of-scope items, change control, and acceptance criteria defined while you still have leverage, not discovered during the project.
How to Write ERP Requirements That Actually Differentiate
The test for a good requirement is simple: could a competent vendor answer no? If every vendor answers yes, the requirement does not help you decide. “System supports multi-currency” fails the test. “System supports actual-cost inventory with landed cost allocation across containers arriving on split shipments” passes it, because now some vendors have a strong native answer, some need an ISV, and some need custom work. That spread is exactly the information a selection is supposed to produce.
Requirements like these come from your operators, not your org chart. The people who process the exceptions, close the books, and run the warehouse know where the current system bends. Getting two or three workshops of their time during requirements produces a sharper RFP than months of document review.
Total Cost Beyond Year One
For Microsoft-platform evaluations specifically, three ongoing cost realities belong in your model from the start. First, Dynamics 365 licensing needs to be mapped to actual roles and usage, especially now that Microsoft’s license enforcement ties license validation to security roles. Second, D365 F&SCM runs on Microsoft’s One Version cadence of four service updates per year with at least two required, which means update review and regression testing are a permanent operating cost, not a project cost. Third, support and managed services for years two through five typically exceed the year-one implementation figure that gets all the attention. A selection that models these honestly avoids the budget surprise that sours so many ERP investments in year two.
4 Questions to Answer Before You Send Anything to Vendors
- What are we actually trying to fix? If the current system’s problems are process and data problems, new software alone will faithfully reproduce them.
- Who owns this decision internally, and do they have real availability? Selection is a project. Projects without dedicated internal ownership drift.
- What is our appetite for standardization? The more willing you are to adopt standard processes, the cheaper and safer the project. That is a leadership decision to make before selection, not a discovery to make during implementation.
- What does support look like after go-live? The strongest selections consider the full lifecycle, including who maintains the system, applies updates, and supports users in year two and beyond.
Where a Partner Like Avantiico Fits
Avantiico works with organizations evaluating Dynamics 365 Finance and Supply Chain Management, and we are direct about what that means: we are a Microsoft Solutions Partner with Finance and Supply Chain specializations, and we believe in the platform for the mid-market and enterprise clients we serve. What we bring to a selection is deep product knowledge and real implementation and managed services experience, so you hear what D365 does well and where it will require ISVs, configuration trade-offs, or process change. If D365 is on your shortlist, that depth helps you evaluate it accurately rather than optimistically. If it is not the right fit for your business, finding that out during selection costs a few weeks. Finding it out during implementation costs a great deal more.
We also help clients think past go-live from the start, because the selection decision includes a support decision, whether it is written down or not. A system chosen with a realistic support and update model behind it is a system that stays healthy.
FAQs About ERP RFP Consulting
An ERP request for proposal (RFP) is the structured document and process an organization uses to solicit and compare ERP vendors and implementation partners: requirements, scenarios, commercial questions, and evaluation criteria. The quality of the RFP largely determines the quality of the answers you get back.
For mid-market organizations, three to six months is typical from requirements through contract: requirements workshops, RFP issuance and response, scenario demos, reference checks, and contract negotiation. Compressing it much further usually means skipping the scenario demos or the contract review, which are the two steps that catch the expensive mistakes.
It depends on where you are. If you genuinely do not know which platform category fits, a neutral advisor for the early narrowing can help. Once a platform is on your shortlist, a partner with deep product expertise gives you sharper answers about real fit, provided they are honest about the platform’s limits as well as its strengths. Ask any consultant, neutral or not, how they are compensated and what they gain from each outcome.
Three to five vendors is the productive range for the RFP itself, narrowed to two or three for scenario demos. Beyond that, evaluation effort grows faster than decision quality.
