Your inventory lives in five systems. Your customers see one brand.

NetSuite with SuiteCommerce for unified inventory, order management, and financials across DC, store, marketplace, and web. We deliver for mid-market retail and eCommerce operators across specialty grocery, beauty and cosmetics, hybrid B2C+B2B brands, and multi-channel sellers running Shopify, Amazon, and Walmart alongside their own storefront. We're also a top-ranked NetSuite partner on G2.

Why Now
The Number Your Board Should See
73%
of mid-market retailers run inventory across at least five disconnected systems.

DC, store POS, marketplace, web storefront, and a returns platform each carry their own counts on their own cadence. Customers see one brand, but your team reconciles five datasets every morning before anyone can answer a basic stock question.

PCI 4.0
DSS requirements in full effect

Expanded scope, stricter control documentation, and continuous monitoring expectations. Retailers using shared payment infrastructure are recalibrating compliance posture.

50
Sales tax jurisdictions post-Wayfair

Economic nexus thresholds vary by state. Manual tax calculation breaks down quickly at this volume; automated registration, collection, and filing is the realistic path for multi-state sellers.

AI
Personalization is now expected, not optional

Customers expect personalized experiences across every channel. Retailers without a unified customer data layer cannot deliver, and the competitors who can are taking the share.

The modules that matter for retail

Five NetSuite modules that earn their place in retail.

Retailers don't need every NetSuite module. They need the few that earn their place on Black Friday, during the Q4 peak, and through post-holiday returns season: pricing engines that handle real promotions, forecasting that survives seasonality, analytics that tie POS data to merchandising, asset tracking for the fixtures and hardware that define a store, and commerce that runs both consumer and wholesale on one platform. These are the five we configure when the work is real.
NetSuite
SuitePromotions

Promotion rules, discount codes, BOGO structures, tiered loyalty programs, and gift card management, all configurable without pulling a developer in every time merchandising wants to run a new campaign. Useful when the promotional calendar currently depends on one person who knows where the Excel workbook lives.

NetSuite
Demand Planning

Seasonal forecasting tuned to retail calendars, holiday peak scenarios, returns-rate modeling, and safety stock that accounts for channel lift during promotional windows. Useful when buys currently happen on gut feel and post-holiday inventory always tells a story nobody wanted to read.

NetSuite
NetSuite Analytics Warehouse

POS transaction data, marketplace velocity, category-level margin trends, and buyer-driven merchandising KPIs integrated with the ERP transaction layer. Useful when store managers get last week's comp report on Wednesday and merchandising decisions run two cycles behind what the data is saying.

NetSuite
Fixed Assets Management

Store fixtures, POS hardware, kitchen and prep equipment, leasehold improvements, and technology refresh cycles tracked with automated depreciation and lease accounting. Useful when the last store opening had a capex schedule in a notebook and auditors keep asking where the fixed asset register lives.

NetSuite
SuiteCommerce B2C + B2B

Two commerce motions on one platform. Consumer checkout runs on SuiteCommerce Advanced with guest buying, promotional pricing, and loyalty programs. Wholesale buyers operate in the same environment with customer-specific contract pricing, credit limits, net-30 terms, trade discount schedules, and a dedicated B2B portal with approval workflows. The two channels share the same inventory layer, item master, and fulfillment floor. For DTC brands pivoting into wholesale and wholesalers adding a consumer channel, the two models live together instead of in parallel systems.

Industry Challenges

Challenges every retail and eCommerce operator is dealing with.

Sixteen challenges across four buckets, organized around how retail and eCommerce buyers think about their work. Click through to see what each one costs and how GSI solves it.

01
Inventory is in five systems. None of them agree.
02
Oversells on the web during peak cost us real money.
03
Amazon, Shopify, and our ERP are out of sync by hours.
04
Returns data takes weeks to reach merchandising.
Reconciliation drag
"Our inventory is in five systems and none of them agree. Every morning starts with a reconciliation fire drill."

DC, store POS, marketplace listings, web storefront, and returns platform each carry their own inventory counts. When they disagree, customer-facing experiences break: oversells, backorders, missed fulfillment windows.

How GSI Solves This · NetSuite
NetSuite Advanced Inventory Management as the unified system of record. SuiteCommerce, POS, and marketplace connectors sync against one inventory layer, with real-time availability across channels and reconciliation work that drops to near zero.
Peak revenue at risk
"Oversells on the web during peak shopping days cost us six figures and damage trust."

When web inventory is out of sync with physical inventory, customers place orders that can't be fulfilled. Oversells during Black Friday or product launches are direct margin loss and brand damage that lingers.

How GSI Solves This · NetSuite
NetSuite with real-time ATP (available-to-promise) calculations across all channels. Safety stock rules by SKU and channel, automatic hold releases, and peak-ready inventory allocation.
"Amazon, Shopify, and our ERP are out of sync by hours. We find out about issues from customer emails."

Marketplace connectors that run on schedules (vs. real-time) create lag between what the ERP says and what the marketplace shows. Customers see inaccurate availability; sellers eat the cost of cancellations.

How GSI Solves This · NetSuite
NetSuite SuiteCloud integrations for Amazon, Shopify, Walmart Marketplace, and eBay with real-time inventory sync, order ingestion, and fulfillment confirmation. Sync delays fall from hours to minutes.
"Returns data takes weeks to reach merchandising. By then, we've already ordered more of what isn't selling."

Return reason codes, fit issues, and category-level return rates are critical merchandising signals. When that data lives in a separate returns system and rolls up weekly, merchandising decisions happen on stale information.

How GSI Solves This · NetSuite
NetSuite returns management unified with merchandising. Return reasons flow into item-level analytics in real time. Buyers see return patterns before they place the next purchase order.
01
Customer data is split across CRM, POS, web, and email.
02
Personalization is table stakes and we can't deliver it.
03
Loyalty program data never makes it to merchandising decisions.
04
Customer service can't see order history across channels.
"Customer data is split across CRM, POS, web, and email platforms. We can't get a single view."

Siloed customer data means marketing can't target, service can't resolve, and merchandising can't segment. Every team is working from a partial view.

How GSI Solves This · NetSuite
NetSuite CRM as the unified customer record. Purchase history across channels, loyalty status, service interactions, and marketing engagement in one profile. HubSpot integration layers marketing attribution on top.
Competitive disadvantage
"Personalization is table stakes for our customers and we can't deliver it."

Customers expect personalized recommendations, targeted offers, and experiences tied to their purchase history. Retailers without a unified customer data layer lose to competitors who deliver relevance at scale.

How GSI Solves This · NetSuite
NetSuite customer 360 feeding SuiteCommerce personalization engines, abandoned cart recovery, and targeted promotions. Customer segmentation runs on actual behavior rather than a marketer's best guess.
"Our loyalty program data never makes it to merchandising decisions."

Loyalty platforms often sit outside the ERP. Top customer behavior, LTV, and category preference don't inform buying and assortment decisions, so merchandising optimizes for the average customer instead of the best one.

How GSI Solves This · NetSuite
NetSuite loyalty integration with merchandising analytics. LTV-weighted demand forecasting, best-customer cohort analysis, and assortment decisions that reflect who is driving the margin.
"Customer service can't see order history across channels. They transfer the call three times."

When service reps can only see their channel's orders, they can't help customers who shopped across channels. Multiple transfers, repeat explanations, and unresolved issues drive NPS down.

How GSI Solves This · NetSuite
NetSuite customer service with cross-channel order visibility. Every rep sees every transaction across POS, web, marketplace, and phone orders, which makes one-call resolution realistic.
01
PCI DSS 4.0 scope expanded and we're not ready.
02
State sales tax post-Wayfair is an administrative nightmare.
03
State privacy laws (CCPA, CPRA, Virginia) keep multiplying.
04
ADA accessibility lawsuits are costing us settlements.
PCI 4.0 enforcement active
"PCI DSS 4.0 scope expanded and our security posture isn't ready."

PCI DSS 4.0 brings expanded scope requirements, stricter documentation, and continuous monitoring expectations. Retailers relying on annual attestation are exposed.

How GSI Solves This · Cybersecurity + NetSuite
vCISO-led PCI DSS 4.0 program with NetSuite payment architecture, tokenization, SIEM monitoring, and continuous compliance evidence. The result is being audit-ready year-round rather than scrambling at assessment time.
Revenue at risk
"State sales tax post-Wayfair is an administrative nightmare. We're out of compliance in three states."

Economic nexus thresholds vary state by state. Manual tax tracking across 50 jurisdictions breaks down quickly, and unreported liability compounds until a state audit surfaces it.

How GSI Solves This · NetSuite
NetSuite SuiteTax with Avalara or Vertex integration. Automated nexus monitoring, rate lookups by address, registration workflow, and direct filing in registered states.
Multi-state patchwork
"State privacy laws (CCPA, CPRA, Virginia, Colorado, Connecticut) keep multiplying. We can't keep up."

Multiple state privacy laws with overlapping but distinct requirements: data subject rights, opt-out signals, sensitive data categories, B2B exemptions. Manual compliance at retail scale breaks down fast.

How GSI Solves This · Cybersecurity + NetSuite
NetSuite customer data architecture with state-aware privacy controls, automated DSAR workflows, opt-out signal processing, and data retention policies. One framework that handles the multi-state patchwork.
Settlement exposure
"ADA accessibility lawsuits are costing us settlements. Our site fails WCAG audit every quarter."

Retail websites are high-profile ADA targets. Non-compliant sites draw demand letters and settlements, plus reputational damage when customers share their experience publicly.

How GSI Solves This · Cybersecurity + Commerce
SuiteCommerce accessibility configuration aligned to WCAG 2.2 AA, automated accessibility testing in CI/CD, and documented remediation trail for ongoing compliance.
01
We just acquired a brand with a different ERP. Integration is stuck.
02
Going international, EU VAT and local tax is a wall.
03
PE sponsor wants Day-5 close. We're at Day 20 with manual reconciliation.
04
B2B wholesale is growing but our ERP is consumer-only.
M&A integration stall
"We just acquired a brand with a different ERP. Integration has been stuck for nine months."

Post-acquisition ERP integration in retail often gets deferred because the operational model is so different between brands. Two ERPs running in parallel means two close cycles, two reporting hierarchies, and duplicated master data.

How GSI Solves This · NetSuite
NetSuite OneWorld M&A integration methodology. Chart-of-accounts harmonization, master data consolidation, brand-specific reporting overlays, and phased migration that doesn't disrupt either brand's operations.
"Going international. EU VAT, UK VAT, and local tax is a wall we can't see over."

International retail expansion introduces multi-currency pricing, country-specific tax (VAT, GST), customs documentation, and country-level statutory reporting. Errors in any one of these areas create exposure in every country you ship to.

How GSI Solves This · NetSuite
NetSuite OneWorld with country-specific tax configuration, localized financials, multi-currency inventory, and statutory reporting for US, UK, EU, Canada, Australia, and APAC.
Sponsor pressure
"PE sponsor wants Day-5 close. We're at Day 20 with manual channel reconciliation."

PE-backed retailers inherit extended close cycles driven by multi-channel reconciliation. Sponsors expect the same close rhythm as any other portfolio company, which isn't realistic without unifying the underlying data architecture.

How GSI Solves This · NetSuite
NetSuite close acceleration methodology for retail. Automated channel reconciliation, unified inventory costing, and continuous consolidation. Day-5 close is achievable with a disciplined monthly process.
"B2B wholesale is growing but our ERP is consumer-only. We're running deals in spreadsheets."

Retailers that develop B2B or wholesale channels often retrofit consumer ERPs for B2B workflows. Consumer-only systems can't handle contract pricing, credit terms, trade programs, or buyer portals cleanly.

How GSI Solves This · NetSuite
NetSuite B2B commerce with customer-specific pricing, credit management, trade program administration, and buyer self-service portals. The same platform serves both consumer and wholesale on a single inventory layer.
Quick Answers

Questions retail and eCommerce operators ask first.

The short version. For regulatory detail, case study depth, or differentiation, keep reading below.

Does NetSuite handle multi-channel inventory as the single source of truth?

Yes, and it's the core reason most retailers land here. NetSuite Advanced Inventory Management sits underneath SuiteCommerce, POS integrations, and marketplace connectors as the unified system of record. Real-time ATP across DC, store, marketplace, and web. Retailers migrating from fragmented systems typically cut their reconciliation work to near zero within a quarter.

We're on Shopify, Amazon, Walmart, and eBay. How does NetSuite integrate?

Native connectors for Shopify, Amazon Seller Central, Walmart Marketplace, and eBay handle real-time inventory sync, order ingestion, fulfillment confirmation, and return handling. NetSuite holds the inventory and order truth, and each marketplace acts as a sales channel — direct integration rather than a middleware layer.

What about PCI DSS 4.0, can GSI deliver that end to end?

Yes. Cybersecurity sits on the same bench. We deliver vCISO-led PCI DSS 4.0 programs with NetSuite payment architecture, tokenization, SIEM monitoring, scope reduction, and continuous compliance evidence. One team runs both the ERP and the PCI compliance work, instead of handing PCI off to a referred partner.

Is state sales tax across 50 states solvable?

Yes. NetSuite SuiteTax with Avalara or Vertex integration handles automated nexus monitoring by state, real-time rate lookups by ZIP, registration workflow, collection, and direct filing. Economic nexus tracking runs continuously rather than once a year.

We're migrating from Microsoft GP, NAV, or Business Central. How painful?

Microsoft GP to NetSuite is the most common retail migration we run. Typical timeline is 4 to 7 months on the DREAM methodology. Most of the work goes into master data cleanup and channel integration rather than core accounting conversion. See the case study below for a published GP-to-NetSuite reference.

Can you handle both consumer retail and B2B wholesale on the same platform?

Yes. NetSuite B2C (SuiteCommerce) and B2B commerce coexist on one platform. Customer-specific pricing, credit terms, trade programs, buyer portals, and wholesale order flows live alongside consumer checkout, with a single inventory layer feeding both channels.

We're on a homegrown order management system we built ourselves. How does that migrate?

Homegrown migrations work differently from GP or Business Central migrations. Your business logic lives in custom code rather than a documented module, and financials often sit in a separate tool entirely. The work is data extraction from your database, discovery workshops that capture every rule currently buried in code, and a phased cutover where the homegrown system stays read-only for historical reference while NetSuite takes over orders, inventory, financials, and marketplace sync. Timelines usually run 4 to 7 months on DREAM, depending on how many marketplace channels and carrier integrations are in scope.

Are we too small for GSI? We're a sub-$20M eCommerce operator.

No. Our retail and eCommerce engagements run from emerging multi-channel brands around $5M up through enterprise operators on multi-entity NetSuite OneWorld. Scope and price track operational complexity rather than headcount. A single-entity eCommerce operator with three marketplace channels runs differently from a fifty-location retailer with international expansion. We publish scope and price at the end of the assessment instead of before it.

PCI DSS 4.0 (Payment Card Security)

Payment Card Industry Data Security Standard 4.0 brings expanded scope, stricter documentation, and continuous monitoring requirements. Required for any retailer accepting card payments online, in-store, or through marketplaces.
4.0 in full effect

State Sales Tax (Post-Wayfair Nexus)

Frequently Asked

The questions retail and eCommerce operators ask us most.

Yes. SuiteCommerce Advanced for full-featured web storefront, SuiteCommerce InStore POS, and SuiteCommerce MyAccount for customer self-service. We implement, theme, and integrate against NetSuite as the unified system of record.

Yes. Native connectors for Amazon Seller Central, Walmart Marketplace, eBay, and Shopify with real-time inventory sync, order ingestion, fulfillment confirmation, and return handling. Direct NetSuite integration rather than middleware.

Yes. NetSuite Order Management supports buy-online-pickup-in-store, ship-from-store, curbside, and same-day delivery orchestration. Inventory allocation rules by channel, fulfillment cost optimization, and customer-facing pickup workflows.

Yes. NetSuite OneWorld with country-specific tax (VAT, GST), multi-currency pricing, localized financials, statutory reporting, and customs documentation. We configure against actual country requirements rather than dropping in a generic template.

It depends on scope. Single-entity retail with SuiteCommerce runs 4 to 6 months on DREAM. Multi-entity OneWorld with international expansion runs 6 to 10 months. Microsoft GP migrations typically run 5 to 7 months. We publish timelines at the end of the assessment instead of estimating before it.

Both, though for retail we lead with NetSuite. GSI is ranked #1 on G2 for NetSuite for five consecutive years and is an Oracle Platinum Partner with 500+ JDE projects. We route the platform conversation based on your operational profile rather than our bench utilization.
