An AI agent here would add cost and non-determinism without adding value. Keep it simple and deterministic. **Recommendations:** - Before buying RPA, check whether native ERP workflow, scheduled jobs, or simple API integration can do the job with even less maintenance. - Use RPA specifically where legacy screens are the only interface and vendors offer no API. - Document the automated rules thoroughly so script maintenance does not depend on one person. - Set up monitoring and alerts, since silent RPA failures create data backlogs. - Re-run this selector if the process later absorbs documents, emails, or judgment steps. #### Hybrid: RPA Backbone With AI Components **Min:** 35 **Max:** 64 **Verdict:** Your process mixes deterministic steps with pockets of unstructured data or judgment. The strongest pattern here is a hybrid: deterministic integration or RPA moves the data and executes transactions, while AI components handle the reading, extraction, and classification steps that rules cannot. This is the most common pattern in real ERP automation today. **Recommendations:** - Map the process step by step and label each as deterministic or judgment-based before selecting tools. - Use AI for the intake steps, such as document extraction and email classification, and deterministic automation for ERP transactions. - Insert a confidence threshold between the AI and transactional steps so low-confidence cases route to humans. - Prefer API-level integration over screen automation wherever APIs exist; save RPA for true legacy gaps. - Design the handoffs first; most hybrid automation failures happen at the seams, not inside the components. #### AI Agents Are the Right Fit **Min:** 65 **Max:** 100 **Verdict:** Your process is defined by unstructured inputs, variability, and judgment, which is precisely where rule-based RPA breaks down and AI agents excel. An agent can read, interpret, decide within guardrails, and escalate what it cannot handle, adapting to variation without script rewrites. **Recommendations:** - Start with the agent in recommend-and-review mode, granting autonomy only as measured accuracy earns it. - Define explicit guardrails: what the agent may do, spending or quantity limits, and mandatory escalation triggers. - Integrate through APIs and business objects so agent actions are validated by the ERP's own business logic. - Log every agent decision with its reasoning for auditability, especially in regulated environments. - Baseline current cost and error rates now so the agent's ROI is provable within one quarter. ## Content **Intro:** This free selector tells you whether classic RPA, modern AI agents, or a hybrid of the two is the right technology for a specific process you want to automate. It is built for IT leaders, automation CoE owners, and operations managers at manufacturers who face vendor noise from both camps and need an objective answer grounded in the process itself. Answer nine questions about data structure, variability, judgment, and system access, and you get a clear technology recommendation with implementation guidance in about two minutes. **Sections:** #### The real difference between RPA and AI agents **Body:** RPA replays deterministic actions: it clicks, types, and copies exactly as scripted, which makes it fast, cheap, and predictable on structured, stable processes, and brittle everywhere else. AI agents reason about goals: they read unstructured content, interpret context, choose among actions within guardrails, and escalate when uncertain, which makes them resilient to variation but non-deterministic and dependent on good guardrail design. Neither is universally better. The selector scores your process on the dimensions that actually discriminate, such as data structure, variability, judgment, exception novelty, interface availability, and rate of change, because those, not vendor preference, determine which technology survives contact with production. #### What the scoring dimensions reveal **Body:** Each question maps to a failure mode of one technology or the other. Low scores describe RPA territory; high scores describe agent territory; the middle describes the hybrid pattern that dominates real ERP automation. Four signals carry particular weight: **Bullets:** - Unstructured inputs like emailed POs and PDF invoices defeat rules but are routine for AI extraction. - Frequent process change breaks RPA scripts, while agents adapt through updated instructions. - Heavy judgment share means rules cannot cover the cases; agent reasoning with escalation can. - Stable legacy screens with no APIs remain the one place RPA is genuinely irreplaceable. #### Interpreting a hybrid result **Body:** Most mid-market ERP processes land in the hybrid band, and that is not a compromise verdict; it is the architecture leading manufacturers actually deploy. The pattern is consistent: AI handles the perception layer, reading documents, classifying emails, and resolving ambiguous references like customer part numbers, while deterministic integration executes the transaction layer, creating orders, posting invoices, and updating records through ERP APIs where behavior must be exact and auditable. The design discipline that makes hybrids work is the seam: a confidence threshold between the AI layer and the transaction layer, so anything the AI is unsure about routes to a human instead of into your ERP. #### How Netray builds the right automation, not just the fashionable one **Body:** Netray designs and builds automation across the whole spectrum for enterprise ERP environments, including Infor SyteLine, Infor LN, and Baan: deterministic API integrations, AI document and email processing, and full agentic workflows with guardrails and audit trails. Because we are not an RPA vendor or a pure AI shop, our recommendation follows your process rather than a product line. We typically start with a one-week process analysis that applies this same selector logic in depth, then deliver a reference architecture and fixed-price implementation plan for the approach that fits. **Cta:** Get a one-week process analysis from Netray and a definitive architecture recommendation for your automation. **Faq:** #### We already own an RPA platform. Should we still consider AI agents? **Answer:** Yes, for the processes your RPA backlog keeps rejecting. Every RPA program accumulates a list of candidates that failed feasibility because inputs were unstructured or variability was too high; those rejects are often ideal AI agent use cases. Your existing RPA investment stays valuable for the structured, stable processes it already runs, and in hybrid designs your RPA bots can even serve as the execution layer that AI components feed. #### Are AI agents riskier than RPA because they are non-deterministic? **Answer:** They carry a different risk profile, not necessarily a higher one. RPA fails silently and deterministically: a changed screen layout can corrupt every transaction in a batch the same wrong way. Agents are non-deterministic but can know when they are uncertain, escalate to humans, and log their reasoning. In practice, a well-guardrailed agent with confidence thresholds and ERP-level validation often produces fewer bad transactions than a brittle script. The key is granting autonomy gradually as measured accuracy earns it. #### Is RPA becoming obsolete now that AI agents exist? **Answer:** No, but its territory is shrinking to what it does best: deterministic execution against legacy systems that offer no APIs. Processes that were forced into RPA despite unstructured inputs or judgment requirements are migrating to AI agents, and new automation increasingly starts with API integration plus AI rather than screen scripting. For a manufacturer, the practical takeaway is to stop asking which platform to standardize on and start matching each process to the technology its characteristics demand. ## Search terms RPA vs AI agents, RPA or AI which to choose, AI agents vs robotic process automation, when to use RPA, intelligent automation selection, RPA replacement AI, agentic automation vs RPA --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
