## What Businesses Build with Ollie Hub

<Tabs>
  <Tab title="Complex Checkout Logic">
    **"We handle enterprise checkout flows that our platform couldn't support"**

    ```typescript title="Custom Checkout Processing" icon="shopping-cart" theme={"system"}
    export const handler = async (event) => {
      const orderData = JSON.parse(event.body);
      
      // Complex business rules the platform doesn't support
      const customPricing = await calculateEnterpriseDiscount({
        customer: orderData.customer,
        items: orderData.items,
        volume: orderData.totalValue,
        paymentMethod: orderData.payment.method
      });
      
      // Multi-channel inventory reservation
      await reserveInventoryAcrossChannels(orderData.items, orderData.storeCode);
      
      // Custom payment flow for B2B customers
      if (orderData.customer.type === 'b2b') {
        await createCreditTermsOrder(orderData, customPricing);
        await notifyAccountManager(orderData.customer.accountManager);
      } else {
        await processImmediatePayment(orderData, customPricing);
      }
      
      // Sync to ERP and fulfillment systems
      await syncToERP(orderData, 'order_created');
      await triggerFulfillmentWorkflow(orderData);
      
      return {
        statusCode: 200,
        body: JSON.stringify({ 
          orderId: orderData.id,
          finalPrice: customPricing.total,
          estimatedDelivery: customPricing.delivery
        })
      };
    };
    ```

    **What this enables:**

      const inventoryUpdate = JSON.parse(event.body);
      
      // Handle inventory changes from any source
      if (inventoryUpdate.type === 'stock_change') {
        const { sku, quantity, location, reason } = inventoryUpdate;

        await upgradePackaging(normalizedOrder);
      }
      
      // Custom pricing and tax calculations per marketplace

        marketplace: orderWebhook.marketplace,
        priorityLevel: fulfillmentRules.priority
      });
      
      // Sync to unified order management system

## Integration Problems That Are Now Solvable

Stop being limited by what SaaS platforms support. Add the custom logic your business actually needs.

<Accordion title="The Old Way: 'Sorry, that's not supported'">
  **Common scenarios that cost \$50K+ or were impossible:**

  * **E-commerce Platform → ERP:** "We can sync orders, but not your custom pricing rules or allocation logic"
  * **Payment Gateway → Loyalty System:** "We can't calculate points based on your tier structure and purchase history"
  * **Marketplace → Inventory:** "We can't reserve stock across channels or apply your fulfillment priorities"
  * **Order Management → Shipping:** "We can't apply your custom packaging rules or carrier selection logic"
  * **Analytics Platform → BI Tools:** "We can't calculate your custom profit margins or attribution models"

  **The result:** Accept limitations, pay for expensive enterprise solutions, or build custom infrastructure teams.
</Accordion>

<Accordion title="The Ollie Hub Way: Custom Logic in Minutes">
  **Now you can build exactly what you need:**

  ```typescript title="Custom E-commerce Platform → Multiple Systems Integration" icon="arrows-pointing-out" theme={"system"}
  export const handler = async (event) => {
    const platformOrder = JSON.parse(event.body);
    
    // Custom business logic the platform doesn't support
    if (platformOrder.customer.type === 'b2b') {
      // Apply B2B-specific pricing and credit terms
      const customPricing = await applyB2BPricingRules(platformOrder);
      await createCreditTermsInvoice(platformOrder, customPricing);
    }
    
    // Smart inventory allocation across channels
    await allocateInventoryAcrossChannels({
      order: platformOrder,
      channelPriority: await getChannelPriority(platformOrder.source),
      reserveForHighValue: platformOrder.total > 1000
    });
    
    // Multi-system sync with custom business rules
    await Promise.all([
      syncToERP(platformOrder, { includeCustomFields: true }),
      updateInventorySystem(calculateSmartReorderLevels(platformOrder)),
      notifyFulfillmentTeam(optimizeFulfillmentRoute(platformOrder)),
      triggerCustomShippingWorkflow(platformOrder)
    ]);
    
    return { statusCode: 200, body: 'All systems updated with custom logic' };
  };
  ```

  **What this does that wasn't possible before:**

  * ✅ Apply B2B-specific pricing and credit terms the platform doesn't support
  * ✅ Smart inventory allocation across multiple channels based on custom rules
  * ✅ Sync to ERP systems with custom field mapping and business logic
  * ✅ Coordinate fulfillment across warehouses with cost and SLA optimization
  * ✅ Add custom workflows that enterprise platforms charge extra for

  **Cost:** $5/month in function execution vs. $75,000 enterprise customization
</Accordion>

<Accordion title="Real Integration Examples Now Possible">
  **Previously impossible/expensive integrations our customers built:**

  * **E-commerce:** Custom loyalty calculations that trigger across Stripe, Klaviyo, and Salesforce
  * **SaaS:** Usage-based billing that syncs between your app, Stripe, and accounting systems
  * **Content:** Auto-posting to social media with AI-generated captions when blog posts publish
  * **Support:** Smart ticket routing based on customer tier, product type, and team availability
  * **Marketing:** Lead scoring that combines data from website, email, and sales interactions
  * **Operations:** Inventory reordering that considers seasonal trends, supplier lead times, and cash flow

  **All built in hours, not months. All running for dollars, not thousands.**
