E-Commerce Company Cuts Data Costs 56% with Automated Fivetran Migration in 3 Weeks

The Situation

A mid-market e-commerce company with 25 data sources powering their analytics platform faced a critical decision. Fivetran’s March 2025 pricing change to per-connector billing had eliminated their bulk discounts, sending monthly costs soaring from $35K to over $48K during peak seasons.

The VP of Data & Analytics received an ultimatum from finance: find a solution or cut data sources. Neither option was acceptable for a business dependent on real-time customer insights.

The challenge? Years of investment in data pipelines, hundreds of custom transformations in dbt, and the prospect of a 6-month manual migration that could disrupt the entire business.

The Challenge

Unpredictable and Escalating Costs

“We couldn’t budget anymore. One promotional campaign would spike our costs by 40%.”

The new per-connector pricing meant each of their 25 integrations—Salesforce, Shopify, Google Analytics, databases—was billed separately. Volume-based Monthly Active Row (MAR) calculations created wild swings month-to-month.

Additional costs piled up:

• $8K/month for dbt Cloud to handle transformations Fivetran couldn’t do natively
• Separate charges for transformation runs beyond 5,000/month
• Real-time streaming locked behind premium Enterprise tier pricing

Technical Limitations Slowing the Business

15-minute minimum sync intervals were too slow for inventory management. Business analysts waited days or weeks for new data requests. Partner integrations took 6 months to implement manually.

The real-time capabilities needed for competitive advantage? Available only on enterprise plans costing 3-4x more.

Migration Seemed Impossible

The data team evaluated alternatives but dreaded the reality: manually recreating 25 connectors, converting hundreds of dbt transformations, testing everything, and managing cutover risk. Minimum 6 months. Maximum disruption.

“We were trapped. Stay and bleed money, or face a migration that could break the business.”

The Solution: Automated Migration with Nexla

What Made This Different

Instead of a manual, months-long replatforming project, Nexla’s AI-powered automation turned migration into a streamlined 3-week transition with minimal engineering effort.

Week 1: Intelligent Discovery & Automated Conversion

Nexla’s AI analyzed the existing Fivetran environment automatically:

The platform scanned all 25 connectors and extracted configurations, credentials, schemas, and sync patterns without manual documentation. Within hours, it had mapped the entire data infrastructure.

AI-powered transformation conversion analyzed dbt code and Fivetran transformations:

• 80% automatically converted to no-code visual workflows
• 20% translated to optimized Python/SQL within Nexla’s framework
• Zero information loss, complete business logic preservation

The automation handled:

• Credential mapping and authentication setup
• Incremental load patterns and CDC replication
• Table selections and filtering rules
• Downstream destination configurations

Week 2: Validation & Parallel Operation

While both systems ran in parallel, Nexla’s built-in validation automatically:

• Reconciled row counts in real-time
• Compared schemas for consistency
• Sampled and validated data accuracy
• Flagged any discrepancies for review

The result? 100% confidence in accuracy before cutover, with zero business disruption.

Week 3: Optimization & Cutover

The team fine-tuned monitoring, established governance policies, and trained business users on self-service capabilities. On cutover day, switching from Fivetran to Nexla took hours, not days.

Beyond Migration: New Capabilities Unlocked

The new platform delivered capabilities impossible with Fivetran:

True Real-Time Data Streaming data processing without premium pricing. Inventory updates, customer behavior, and sales metrics now update in under 1 minute instead of 15+ minutes.

No-Code Self-Service Business analysts now create 80% of data flows themselves without engineering support. A data marketplace with 150+ reusable data products (Nexsets) enables discovery and collaboration.

Built-In Transformation Eliminated the $8K/month dbt Cloud expense. All transformations now native to the platform with visual, no-code interfaces and AI-powered assistants.

Predictable Costs Fixed capacity-based pricing instead of variable per-row, per-connector fees. No more budget surprises during promotional campaigns.

The Results

Cost Impact: 56% Reduction

ROI achieved in under 2 months.

Time Savings: 70% Faster Operations

• Partner integrations: 6 months → 3-5 days (97% reduction)
• New data source setup: 2 weeks → 4 hours (90% reduction)
• Pipeline deployment: 2 weeks → 2 hours (98% reduction)
• Data quality incidents: 12/month → 2/month (83% reduction)

Business Impact: 3x Faster Decisions

• Data latency: 15 minutes → real-time (<1 minute)
• Pipeline reliability: 97% → 99.9%
• Self-service adoption: Business users now create 65% of data flows
• Time to insight: 70% reduction

Team Transformation

“Our data engineers finally focus on innovation instead of maintenance.”

Data engineering tickets decreased 45%. The team shifted from firefighting pipeline issues to building AI/ML models and strategic initiatives. Business analysts got immediate access to data through self-service tools.

What Made Automated Migration Possible

AI-Powered Intelligence

Metadata-driven architecture that understands data relationships, patterns, and business logic automatically. Natural language processing converts complex SQL and code into visual workflows.

Universal Connector Framework

Pre-built connectors for 700+ sources with automatic credential mapping, bi-directional flows, and self-optimization.

Data Product Architecture (Nexsets)

Reusable, governed data products that decouple sources from consumers. Built-in lineage, version control, and schema evolution.

Zero-Risk Validation

Automated testing compares systems side-by-side during parallel operation. Real-time quality monitoring catches issues before they impact business.

Customer Perspective

“The automated migration was game-changing. What we expected to be a months-long, risky project turned into a streamlined 3-week transition. Nexla’s AI did the heavy lifting—automatically converting our connectors and transformations. We went from spending weeks configuring each pipeline to having everything recreated in hours. The cost savings are massive, but the real win is how fast we moved and how much more capable our platform is now.”

Key Takeaways

For Data Leaders Evaluating Fivetran Alternatives:

Migration doesn’t have to be painful. AI-powered automation reduces what was once a 6-month manual project to a 3-week streamlined transition with 90% less engineering effort.

Cost predictability matters. Per-connector, per-row pricing creates budget chaos. Fixed capacity-based pricing provides stability.

Self-service is a competitive advantage. When business teams can create their own data flows, innovation accelerates dramatically.

Real-time shouldn’t cost extra. Streaming capabilities should be native, not locked behind premium tiers.
