Ecommerce Finance Systems
Ecommerce Finance Systems. Shopify, NetSuite, and Every System That Sits Between.
ERP selection, Shopify to NetSuite integration, and finance systems design for DTC brands scaling from $15M to $150M and beyond.
Finance Systems Built for How Ecommerce Brands Actually Grow
Most DTC brands hit a systems wall well before they hit an operational one. QuickBooks stops handling inventory. Shopify data lands in accounting as net deposits. Multiple entities, currencies, or channels turn the monthly close into a two-week exercise in Excel gymnastics.
Sataurius scopes, selects, and implements the right finance stack for the stage you are in and the stage you are heading to, and we do it in a way that survives leadership changes, private equity ownership, and international expansion.
What We Handle in an Ecommerce Systems Engagement
- ERP selection: NetSuite, Acumatica, Sage Intacct, Microsoft Dynamics, or Shopify-native stacks.
- Shopify to ERP integration via Celigo, FarApp, Boomi, or custom connectors.
- Amazon, wholesale, and marketplace data flows and marketplace-facilitator tax posture.
- 3PL, WMS, and inventory system integration with landed-cost logic.
- Chart of accounts and item master redesign that supports channel and SKU profitability.
- Multi-entity, multi-currency, and consolidation setup.
- Change management, training, and post-go-live optimization.
How Sataurius Runs Ecommerce ERP and Systems Projects
We run a phased approach: current-state audit, requirements and selection, integration design, phased go-live, and 90-day post go-live optimization. Finance leadership stays in place throughout so the business keeps closing the books and reporting to investors while the platform underneath is rebuilt. Pair with our Technology & ERP practice for non-ecommerce implementations, or with ecommerce fractional CFO services when the project needs executive-level financial ownership.

FAQ
Frequently Asked Questions
When should a DTC brand move from QuickBooks to NetSuite?
Most DTC brands outgrow QuickBooks between $15M and $30M in revenue, or earlier when they run multiple entities, multi-currency, or serious inventory across channels. Signs it is time include manual workarounds for inventory, slow monthly close, and inability to consolidate entities or currencies natively.
How do you integrate Shopify with NetSuite?
Shopify to NetSuite integration usually flows through a middleware connector (Celigo, FarApp, Boomi) that syncs orders, customers, inventory, fulfillments, refunds, and payouts. Sataurius scopes the integration around actual data volume, channel count, marketplace-facilitator tax rules, and the accounting posture (order-level vs. summary journal).
What does a Shopify NetSuite integration cost?
Implementations typically run $40,000 to $150,000 depending on channel complexity, number of entities, and customization. Ongoing middleware fees are usually $6,000 to $18,000 per year. Sataurius scopes and manages the full project so the number is defensible up front.
Do you help with ERP selection for ecommerce brands?
Yes. We run a requirements workshop, evaluate NetSuite, Acumatica, Microsoft Dynamics, Sage Intacct, and Shopify-native middleware options against your channel and inventory footprint, and produce a scored recommendation with total cost of ownership modeled over five years.
Can you rescue a failed ecommerce ERP implementation?
Yes. Most rescues start with a data audit, a redesign of the chart of accounts and item master, and a phased cutover plan that de-risks go-live. We keep the business running while the implementation is stabilized.
How long does an ecommerce ERP implementation take?
A typical Shopify plus NetSuite implementation runs four to nine months from kickoff to stable go-live, depending on entity count, integrations, and data migration scope. Sataurius runs a phased approach so revenue-critical workflows are not held hostage to a big-bang cutover.
