Frequently Asked Questions
How much does SAP Business One cost per year?
SAP Business One for a mid-market company with 75 users costs between $162,000 and $315,000 per year in licensing fees. This does not include the implementation project (typically $500K–$2M), annual maintenance fees (22% of license cost), or ABAP customization work.
Can a custom ERP replace SAP for a manufacturing company?
For many mid-market manufacturers, yes. Slickrock.dev builds custom ERPs that map precisely to your production workflows for $45,000 initial build with $3,500/year maintenance. Over 5 years: $62,500 custom vs. $810,000–$1,575,000 SAP. The key is targeting the 20-40% of ERP functionality your operations actually need.
What is the typical SAP implementation failure rate?
Industry research shows that 20-25% of SAP implementations fail outright, and over 50% exceed their original budget and timeline by 2x or more. The primary cause is the gap between SAP standard functionality and the unique operational workflows of each business, a gap that custom software eliminates by design.
