You just sold the last unit of your bestselling product online and in-store at the same time. Now two customers expect the same item. Someone is going home empty-handed. This happens when online and store systems do not share data. Manual counts and spreadsheets make the problem worse.
A good BigCommerce Implementation can connect your store with a POS system. Stock and order data can then move between both systems. That helps reduce overselling and cuts the time spent checking stock by hand.
Key Takeaways
Understanding Point-of-Sale Systems for Retail
A point-of-sale system does more than take payments. Modern POS tools can track stock, customers, and store sales. They can also share data with other business systems.
For retailers with online and physical stores, that link matters. The POS can help connect store sales with your ecommerce site.
The core parts of a retail POS include:
- Transaction processing: Accept cards, mobile wallets, and cash
- Inventory management: Track stock across store locations
- Customer data: Store purchase history and contact details
- Sales reporting: Show what sells and when
- Hardware: Use scanners, printers, terminals, and card readers
- Software: Give staff a tool for daily store work
A POS with a ready-made BigCommerce connection can make setup easier. It may also reduce the need for extra middleware or custom code.
That matters when planning BigCommerce Development Services. Fewer custom links often mean fewer things to maintain later.

Omnichannel vs. Multichannel: Why the Distinction Matters
Multichannel retail means you sell through more than one channel. You may have a website and a physical store.
Omnichannel retail goes a step further. The channels share data and support the same customer journey.
Here is the practical difference:
Multichannel: A customer buys online but cannot return the item in-store. Stock counts may be separate. Their order history may also stay in one system.
Omnichannel: A customer can shop across several connected channels. Staff can see shared order and stock data when the systems support it.
The omnichannel approach can make shopping easier. Customers may browse on a phone and buy later in a store.
They also expect store stock to be correct. Nobody enjoys driving across town for an item that is not actually there.
BigCommerce POS integration helps connect these sales channels. Data can move between the store and online systems.
The exact data flow depends on the POS connector. Not every connector sends every type of data both ways.
Why BigCommerce Works for Omnichannel Retail
BigCommerce supports selling through many channels. It also offers tools that help connect ecommerce with physical stores.
Key features include:
- Open APIs: Connect BigCommerce with POS and other systems
- POS app options: Connect Square, ConnectPOS, Lightspeed, and other tools
- Multi-location inventory: Track stock across stores and warehouses
- B2B tools: Support business buyers and customer pricing
- BOPIS tools: Support buy online, pickup in-store workflows
BOPIS may need extra setup. BigCommerce says its standard Cornerstone theme does not support the full BOPIS flow by default.
Stencil stores may need theme work. Headless stores can use BigCommerce BOPIS APIs to build the pickup flow.
BigCommerce can support both growing stores and larger retail teams. Its BigCommerce B2B features also help companies that sell to business buyers.
That can be useful for wholesalers and makers that also sell direct to shoppers.
Selecting Your BigCommerce POS: Options Compared
BigCommerce works with several POS systems. The right choice depends on your stores, current tools, and sales process.

Choose ConnectPOS if you want a POS built around connected retail. It can suit stores that need more control over their sales flow.
Choose Square if your stores already use Square. BigCommerce offers a direct connection between the two systems.
Choose Lightspeed if your business already runs on Lightspeed. Connector features can vary, so check your needed data flows first.
Choose Heartland Retail if you sell fashion or apparel. It can also suit retailers with several store locations.
Integrating ERP with BigCommerce POS
Many retailers also use an ERP such as NetSuite. In that case, the POS is only one part of the full setup.
The POS handles store sales. BigCommerce handles online sales. NetSuite may manage stock, orders, and finance data.
All three systems need clear roles. Otherwise, the same record may be changed in more than one place.
A BigCommerce NetSuite Integration can support flows such as:
- Moving supported ecommerce orders into NetSuite
- Syncing product and stock data
- Sending fulfillment updates back to sales channels
- Mapping payment and shipping methods
Oracle explains these data flows in its NetSuite Connector guide. The connector supports several types of commerce data.
Oracle also provides a BigCommerce connector guide. It covers BigCommerce as a supported connector flow.
The NetSuit Connector for BigCommerce still needs careful setup. Payment and shipping methods must map correctly.
Bad mappings can stop orders from moving as planned. That is usually where things start getting squirrelly.
A well-built three-way setup can reduce spreadsheet work. Just remember that your POS may need its own link to NetSuite.
Do not assume every POS sale will reach every system by default. The connector design decides what moves where.
Setting Up Your BigCommerce POS: Step-by-Step
Here is a practical way to connect a POS with BigCommerce.
Step 1: Audit Your Data
Clean your product data before connecting anything. Bad source data can turn into bad synced data very quickly.
Look for duplicate records and mismatched SKUs. Also check product options and customer records.
- Export product lists from both systems
- Use the same SKU format
- Check product options and variants
- Remove duplicate customer records
- Pick the main source for each data type
This work is not exciting. It is still one of the most useful parts of the project.
A connector can move clean data quickly. It can also move bad data quickly.
Step 2: Choose Your POS Solution
Compare POS tools based on how your stores work.
Ask questions such as:
- How many store locations do you have?
- What POS hardware do you already own?
- Do you need an offline sales mode?
- Which system should control stock?
- Do you need store pickup?
- Do you need cross-channel returns?
Your existing tools matter here. Keeping a good POS may make more sense than replacing it.
Step 3: Install and Connect
The exact setup depends on the POS provider.
- Find the approved BigCommerce integration.
- Install the app or connector.
- Approve the requested system access.
- Connect your current POS account.
- Choose the stores and data to sync.
Many marketplace apps use OAuth. OAuth lets the systems connect without sharing normal user passwords.
Custom builds may need their own API accounts. Those setups usually need more technical work.
Next, decide how data should move.
Useful setup choices include:
- Pick the payment type for online orders
- Choose which stock locations should sync
- Map payment methods between systems
- Set the main source for stock data
- Set low-stock rules
- Set out-of-stock rules
Write these choices down. Your future team will thank you.
Nobody wants to guess six months later which system owns the stock count.
Step 5: Initial Sync
Run the first sync with care.
Choose which system holds the main product record. Then move the data in the right direction.
- Sync products from the main system
- Check stock counts in both systems
- Review product and variant matches
- Check customer data when supported
- Look for duplicate records
Avoid making large data changes during this first sync. It makes errors much harder to trace.
Step 6: Test Thoroughly
Test the same tasks your staff and customers will use.
Do not stop after one successful test order.
- Place an order through BigCommerce
- Sell the same item through the POS
- Check the new stock count
- Test supported returns
- Test supported refunds
- Check items with several variants
- Test out-of-stock behavior
Also test less common cases. Those are usually the ones that show up on a busy Saturday.
Returns, gift cards, and customer records may work differently by connector.
Step 7: Go Live and Monitor
Once testing looks good, move the connection into normal use.
Watch the first live orders closely.
- Review stock reports
- Watch connector errors
- Check failed syncs
- Review high-volume items
- Check new payment methods
- Record system changes
Do not treat go-live as the end of the project. New products and store changes can create new mapping issues.
Optimizing Inventory Across Channels
A connected POS gives you a better view of store stock. That does not mean every stock problem disappears.
The rules still matter.
Use inventory buffers: Even fast syncs can have short delays. High-demand products may need a small stock buffer.
Set up location rules: Decide which store or warehouse should ship each order. Good rules can cut needless transfers.
Use low-stock alerts: Warn the team before an item reaches zero. This helps when stock sits across several locations.
Check stock often: Systems can drift after failed syncs or manual edits. Regular checks can catch those gaps early.
Businesses already using NetSuite Services can link store stock with wider NetSuite workflows.
That can be cleaner than running a second stock system beside NetSuite.
The goal is simple. Everyone should know what you have and where it is.
Payment Processing Configuration
Your POS handles payments inside the store. BigCommerce handles payments made through your website.
The two sides still need clean accounting rules.
Key setup steps include:
- Map payment methods: Use clear names across connected systems
- Set payment timing: Decide when each order type is charged
- Use fraud checks: Apply the right checks to online card payments
- Map settlements: Show finance where each payment type posts
BOPIS orders may use a different payment flow from normal shipped orders. Test that flow before launch.
The BigCommerce payment guide explains common mapping issues.
Oracle also has payment mapping guidance. It explains payment and shipping mappings in NetSuite Connector.
Good payment mapping makes month-end work much easier. Bad mapping has the opposite effect.
Advanced Features That Drive Results
Basic POS links focus on stock and orders. Some systems also support extra retail tools.
Features depend on the POS and connector.
Customer loyalty programs: Customers may earn and use rewards across supported sales channels.
Gift cards: Some systems let gift cards work both online and in stores.
Promotions and discounts: Shared offers can reduce manual work across sales channels.
Employee management: Many POS tools can track staff roles, access, and store sales.
Analytics and reporting: Connected data can show sales by item, store, and channel.
Do not assume all these tools sync by default. A connector that syncs stock may not sync loyalty points.
The same is true for returns and gift cards. Check each needed workflow before choosing your POS.
For B2B sellers, BigCommerce B2B features add tools for business buyers.
These can include company accounts, quotes, and special pricing. POS support for those tools depends on your setup.
BigCommerce POS: Strong Fit vs. May Not Be Best Fit
Strong Fit For:
- Online and physical retailers that need shared stock data
- Stores with large catalogs that are hard to track by hand
- Companies using NetSuite that need connected sales data
- Multi-location retailers that need stock views across stores
- Businesses using BOPIS for store pickup
- Growing retailers that plan to add more sales channels
May Not Be the Best Fit For:
- Online-only retailers with no physical store plans
- Very small stores that can still track stock easily
- Stores with unusual product setups that need heavy custom work
- Regulated retailers that need a special POS for their industry

Frequently Asked Questions
What is the main benefit of BigCommerce POS integration for omnichannel retail?
The main benefit is shared inventory across online and store sales. When a customer buys in-store, the website can receive the new stock count. Online sales can also update the store side. This helps reduce overselling and manual stock checks. Staff gets a clearer view of what is available. The exact update speed depends on the POS provider and connector you use.
How does ERP integration enhance a BigCommerce POS system?
ERP integration links sales data with inventory, orders, and financial records. BigCommerce orders can move into NetSuite through a supported connector. Inventory and product data can also sync between systems. This reduces duplicate entry and helps teams use cleaner records. Payment and shipping mappings still need careful setup. POS data may need its own connector, depending on the system and planned data flow.
Can Anchor Group help with BigCommerce POS setup and ERP integration?
Yes. Anchor Group supports BigCommerce development and NetSuite integration for retailers with connected sales channels. The team can review data, map order flows, configure connectors, and test the setup. They can also train staff before launch. After go-live, Anchor Group can help fix sync issues and adjust workflows. That support helps when BigCommerce, the POS, and NetSuite all need to share data.
What inventory challenges does a unified POS and ERP system solve?
A unified setup helps reduce overselling and stock gaps between locations. It can also cut manual reconciliation work. Sales from each channel can update shared inventory records. Staff gets a clearer view of what is available and where. Multi-location rules can help route orders from the right place. Regular checks still matter because failed syncs or manual changes can create new stock gaps.
Is BigCommerce POS suitable for both small businesses and larger retailers?
Yes, but the fit depends on store size and complexity. Small retailers may not need a full POS integration yet. Larger retailers often gain more value from shared inventory and order data. Multi-location stores also benefit from better stock visibility. Enterprise teams may need deeper ERP and reporting links. The best choice depends on your catalog, locations, sales volume, and current systems.
