ERPlisity vs SourceDay
SourceDay has been around for 10+ years and manages $5B in quarterly spend. But their portal-first, cloud-centric model wasn't built for the way most manufacturers actually work. ERPlisity was.

Head-to-Head Comparison
Where each platform stands — no spin, just facts.
Supplier Onboarding
Zero friction
Suppliers respond via email — no portal login, no training, no account setup. Optional portal for power users who want deeper access.
Portal-first
Requires supplier activation on their portal. Claims 100K+ suppliers activated, but adoption depends on training and onboarding effort from your team.
ERP Integration
Schema-aware, on-prem native
Built for on-prem ERP environments. Reads your ERP's version and schema directly — understands field-level differences, not just generic mappings.
Broad but surface-level
500+ ERP integrations — impressive breadth, but integration is connector-based. One-size-fits-most approach that doesn't go deep on any single ERP.
Security Model
Outbound-only, read-first
No inbound firewall rules. Read-only by default, writes require explicit approval. Your IT team will actually approve this — not fight it for months.
Traditional SaaS
Standard cloud integration patterns. May require inbound connections depending on your ERP. Full read/write access is the default.
On-Prem ERP Support
Purpose-built
Designed from the ground up for on-prem ERP environments. Outbound-only architecture means no VPN tunnels, no DMZ headaches, no IT blockers.
Cloud-first mindset
Built primarily for cloud ERPs and SaaS integrations. On-prem support exists but isn't the primary design consideration.
Time to Value
Weeks
Connect to your ERP in days. Start getting supplier updates immediately. No workflow replacement, no multi-month implementation project.
Months
Enterprise implementation cycle. Workflow mapping, supplier onboarding waves, training programs. Plan for 3-6 months before you see results.
Cost
Mid-market pricing
Lean pricing designed for manufacturers who want real ROI without a six-figure commitment. No surprise fees, no bloated implementation costs.
Enterprise pricing
Pricing reflects their enterprise positioning. Implementation, training, and ongoing support costs add up. Built for large procurement teams with large budgets.
Why Teams Switch to ERPlisity
SourceDay built a solid product for cloud-first enterprises. But if you're running on-prem ERP and your suppliers ignore portals, you need a different approach.
Built for On-Prem Reality
Most manufacturers still run on-prem ERPs. SourceDay was built for the cloud-first world. ERPlisity was built for yours — outbound-only, no VPN tunnels, no IT battles.
Suppliers Actually Respond
SourceDay needs suppliers to log into a portal. ERPlisity works through email — so your suppliers respond the way they already communicate. Higher response rates, zero training.
Live in Weeks, Not Quarters
SourceDay's enterprise implementation takes months. ERPlisity connects to your ERP in days and starts delivering value immediately. No workflow replacement required.
What SourceDay Does Well
Credit where it's due — SourceDay has strengths:
- •10+ years of market presence and customer data
- •Large supplier network (100K+ activated)
- •AI/ML risk intelligence for large-scale operations
- •Strong brand recognition in the procurement space
But market presence doesn't solve your on-prem integration challenges. And a large supplier network doesn't help if your suppliers won't log into yet another portal.
The Bottom Line
SourceDay is built for large enterprises with cloud ERPs, big budgets, and the patience for a multi-month rollout. ERPlisity is built for manufacturers who need supplier visibility now — without the portal friction, without the inbound firewall rules, and without the enterprise price tag.

ERPlisity was built for exactly your situation.
Common Questions
Does SourceDay support on-prem ERPs?
SourceDay lists on-prem ERP integrations, but their architecture is cloud-first. ERPlisity's outbound-only model was designed specifically for on-prem environments — no VPN tunnels, no DMZ configurations, no inbound firewall rules.
What about SourceDay's AI/ML features?
SourceDay Intelligence is their ML platform for risk modeling and trend identification. It's impressive at scale. But most mid-market manufacturers don't need predictive risk models — they need their suppliers to confirm PO changes without a 3-day email chain. ERPlisity solves the fundamental problem first.
Can ERPlisity handle the same volume as SourceDay?
ERPlisity is built for the mid-market sweet spot — the manufacturers with 50-500 suppliers who need fast, reliable PO visibility. If you're managing thousands of suppliers across a global supply chain, you have different needs. For everyone else, ERPlisity delivers more value, faster.
What ERPs does ERPlisity support?
ERPlisity works with on-prem ERP systems across vendors. Our schema-aware integration reads your specific ERP version and field structure — not just generic mappings. If it's on-prem, we can connect to it.
