API INTEGRATIONS

US businesses with Salesforce, QuickBooks, and Stripe as three separate systems connected only by manual exports are paying enterprise software prices to do enterprise-scale admin by hand -- a connected API layer makes all three share data automatically

Connect Salesforce or HubSpot to QuickBooks, NetSuite, and Stripe so invoices create themselves at deal close, payment status is visible in the CRM, and subscription data drives customer health scoring without anyone moving files between systems.

Who This Is For

US online retailers scaling above 500 orders per day on Shopify Plus or BigCommerce need their order data connected to a NetSuite or SAP ERP for order management, inventory deduction, and financial consolidation at the scale where manual exports to the ERP become a daily operational failure point. At this order volume, the gap between an order placed and an inventory update posted matters. A Shopify-NetSuite or BigCommerce-SAP integration handles order creation, inventory deduction, and financial posting automatically, removing the manual export step that breaks under high volume.

US SaaS businesses using Stripe for subscription billing and HubSpot or Salesforce for customer relationship management have subscription intelligence, such as MRR, plan tier, trial status, payment failure, and churn, sitting in Stripe where the customer success team cannot see it without leaving the CRM. A Stripe-CRM integration syncs subscription status, MRR, payment events, and cancellation signals in real time so customer success can identify at-risk accounts and expansion opportunities from inside the CRM tool they use every day, without opening a separate Stripe dashboard.

US fintech companies, lending platforms, financial advisory firms, and businesses offering ACH payment initiation need bank account data that their customers authorise them to access via Plaid. Plaid's API provides bank account balances, transaction history, and account verification for ACH initiation. Integrating Plaid with the business's core application enables automated cash flow monitoring, instant account verification for payment processing, and ACH initiation without requiring customers to submit paper voided checks or micro-deposit verification that takes two to three business days.

US sales and customer success teams that use Salesforce or HubSpot as the system of record and Slack as the team's primary communication channel need deal and customer health events to surface in Slack automatically rather than requiring someone to check the CRM dashboard. A Salesforce-Slack or HubSpot-Slack integration posts deal stage changes, closed-won notifications, at-risk customer alerts, and renewal reminders to the relevant Slack channel in real time, so the team acts on information when it is current rather than when someone thought to check the CRM.

/ What's broken

What's Broken

Salesforce and QuickBooks are not connected

US businesses with Salesforce opportunities reaching closed-won and QuickBooks invoices created separately are running a finance-to-sales workflow that depends on a person manually carrying deal data from one system to the other. The invoice is often created hours or a full day after the deal closes. The invoice payment status in QuickBooks is not visible in Salesforce without a staff member checking both and reporting back. When an invoice is overdue, the sales team does not know unless finance tells them. A Salesforce-QuickBooks integration creates an invoice automatically the moment an opportunity reaches closed-won, maps the deal line items and customer record to the correct QuickBooks customer and item fields, and syncs payment status back to the Salesforce opportunity record in real time so both teams see the same current financial state without anyone updating two systems.

Stripe payment data is not visible in the CRM

US SaaS and subscription businesses with Stripe subscription data showing MRR, plan type, trial status, payment failures, and churn events that are not visible in HubSpot or Salesforce are making customer health decisions from incomplete information. The customer success team cannot see which accounts are on trial, which have failed a payment, which have downgraded, and which are approaching renewal inside the CRM they use for daily work. A Stripe-CRM integration syncs subscription status, MRR, plan changes, payment events, and cancellation signals to the CRM customer record in real time, creating the complete account view that customer success and sales teams need to manage retention and expansion proactively.

Shopify and ERP are not connected for high-volume US merchants

US Shopify merchants scaling above 500 orders per day that export order data to NetSuite or SAP manually, even on a scheduled daily export, are operating with an inventory and financial record that is always behind real sales. An order that ships before the export runs deducts from inventory in the ERP hours after it should have. Financial postings lag behind actuals. Fulfilment routing decisions are made on yesterday's inventory rather than today's. A Shopify-ERP integration via API handles order creation, inventory deduction, and financial posting in real time at any order volume, removing the data lag and the manual export task simultaneously.

Twilio SMS and the CRM are not integrated for customer communication

US businesses using Twilio for SMS notifications, alerts, and reminders with no connection to the HubSpot or Salesforce customer record are creating a communication history gap that affects every team that interacts with customers. Messages sent via Twilio are not logged in the CRM. Messages received via Twilio are not visible to the sales or customer success team working in the CRM. A customer's contact history in the CRM is missing every text exchange that went through Twilio. A Twilio-CRM integration logs every SMS sent and received against the correct CRM contact record, giving every team member a complete view of customer communications regardless of which channel the conversation used.

/ What we engineer

What We Do

Each workstream is built by the team that audits it, and wired into the rest of your growth system.

Connect the American business software stack

Ignited Nepal plans and builds API integrations for US businesses connecting Salesforce, HubSpot, QuickBooks Online, NetSuite, Stripe, Shopify Plus, BigCommerce, Twilio, Plaid, and the other platforms that form the core of the American business software stack.

E-commerce ERP integration

For US e-commerce businesses, we build the Shopify-NetSuite or BigCommerce-SAP ERP integration that handles real-time order creation, inventory deduction, and financial posting. We map the Shopify order fields to the ERP item, customer, and transaction records, handle the transformation logic for US tax fields and multi-location inventory, and build error handling for edge cases such as partial fulfilments, returns, and inventory adjustments.

Stripe-CRM integration for SaaS companies

For SaaS companies, we build the Stripe-CRM integration that syncs subscription status, MRR, plan tier, trial state, payment events, and cancellation signals to HubSpot or Salesforce customer records. We map Stripe customer objects to CRM contact and company records, define the sync logic for plan changes and payment failures, and build the customer health score triggers that fire when Stripe events indicate churn risk or expansion opportunity.

Plaid integration for financial services

For financial services firms using Plaid, we build the integration between the Plaid API and the business's core application, covering account authentication, balance and transaction data retrieval, account verification for ACH initiation, and the data storage and refresh logic that keeps bank account data current within the business's system.

CRM-to-Slack integration for enterprise teams

For enterprise businesses connecting CRM to Slack, we build the Salesforce-Slack or HubSpot-Slack integration including deal stage change notifications, closed-won alerts with deal value and account details, at-risk customer alerts triggered by Stripe churn signals or CRM health score drops, and renewal reminders posted to the account owner's Slack channel at a configurable number of days before renewal.

Full integration scope across all US projects

Across all US integration projects we handle OAuth and API key authentication, data field mapping and transformation, error handling and retry logic including Salesforce API rate limit management, monitoring and alerting, and written integration documentation.

/ How it works

Process

  1. Integration diagnostic

    We map the US business software systems in scope, document the manual data flows your team performs between them, and identify the trigger events, data volumes, and transformation requirements for each integration. For Salesforce and NetSuite projects, we review API rate limits and data volumes at this stage to confirm the integration architecture will perform at your order or deal volume.

  2. API access and authentication setup

    We configure OAuth 2.0 for Salesforce, HubSpot, QuickBooks Online, NetSuite, and Shopify, API key authentication for Stripe, Twilio, and SendGrid, and Plaid Link for bank account authentication. We test access to every endpoint in scope before starting the build and document the credential management approach for each system.

  3. Data mapping and transformation design

    We document the field mapping between each system pair, identify US-specific data handling requirements such as US state tax fields, multi-currency for international Shopify stores, and Salesforce custom object structures, and design the transformation logic before building.

  4. Build, test, and error handling

    We build in a staging environment with production-representative data volumes, test all trigger conditions including edge cases such as Salesforce duplicate contacts, Stripe payment retries, and NetSuite inventory adjustments, and implement error handling and retry logic including Salesforce API rate limit back-off and Stripe webhook signature verification.

  5. Monitoring and alerting setup

    We configure integration monitoring with alerting appropriate to the business impact of each data flow. For financial integrations such as Salesforce-QuickBooks and Stripe-CRM, we set alerts for failed invoice creation and missed payment event syncs. For e-commerce integrations, we alert on order processing failures and inventory sync errors that could result in overselling.

  6. Handover and documentation

    We deliver written integration documentation covering architecture, API endpoints, authentication setup, field mapping, trigger logic, error handling, and maintenance procedures. For US enterprise integrations involving Salesforce or NetSuite, we include API governor limit guidance and the monitoring setup your internal team or Salesforce admin should check regularly.

/ Common questions

FAQ

Straight answers on scope, timelines and cost. Anything else, ask us directly.

Ask us directly
How do I integrate Salesforce with QuickBooks Online to automate invoice creation and payment sync for a US business?

Salesforce connects to QuickBooks Online via OAuth 2.0, with integration available through Salesforce's native QuickBooks connector for simpler cases or through a custom API build for businesses with non-standard line item structures or Salesforce custom objects. The integration maps a closed-won opportunity or custom trigger to a QuickBooks invoice creation event, passing the customer name, deal amount, line items, and billing address. Payment status from QuickBooks, specifically paid, partial, or overdue, is synced back to the Salesforce opportunity record via a QuickBooks webhook or scheduled polling call. Ignited Nepal builds this integration including the field mapping for US tax lines, multi-line item opportunities, and the payment status sync logic.

How do I connect Stripe subscription data to HubSpot or Salesforce CRM for a US SaaS company?

Stripe provides webhooks for all subscription lifecycle events including subscription created, updated, trial ending, payment failed, and subscription cancelled. The integration connects these Stripe webhook events to the CRM via a middleware layer that maps the Stripe customer ID to the CRM contact or company record, updates the relevant CRM properties such as MRR, plan name, subscription status, and last payment date, and can trigger CRM workflow automation based on the Stripe event type. Ignited Nepal builds this integration for both HubSpot and Salesforce, including the Stripe customer-to-CRM contact matching logic and the CRM property definitions required to store subscription data.

How do I build a Shopify-to-NetSuite API integration for a high-volume US e-commerce business?

A Shopify-to-NetSuite integration connects Shopify order webhooks to NetSuite's SuiteScript or REST API to create sales orders, deduct inventory, and post financial transactions in real time. The integration requires mapping Shopify customer, product, and order fields to their NetSuite equivalents, handling US state tax fields and shipping cost allocation, managing NetSuite's API concurrency limits under high order volume, and building error handling for NetSuite record creation failures that could result in orders being placed but not recorded. Ignited Nepal builds Shopify-NetSuite integrations including the field mapping for US tax requirements, inventory location mapping for multi-warehouse operations, and the error alerting that flags NetSuite failures for immediate review.

How do I integrate Twilio SMS into HubSpot or Salesforce to log all customer SMS communications?

Twilio provides a messaging webhook that fires when an SMS is sent or received on a Twilio number. The integration connects this webhook to the CRM by matching the customer's phone number to the CRM contact record, creating a CRM activity or communication log entry for each SMS sent and received, and storing the message body, timestamp, and direction against the contact. For outbound SMS triggered by CRM workflow automation, the integration also calls the Twilio API from the CRM trigger. Ignited Nepal builds this bidirectional Twilio-CRM logging integration for both HubSpot and Salesforce, including phone number matching logic for US number formats and the CRM activity timeline entry structure.

What is the best middleware platform for connecting US business systems -- Zapier, Make, MuleSoft, or a custom API build?

Zapier and Make are appropriate for US businesses connecting standard SaaS tools at moderate data volumes where native connectors exist and transformation logic is straightforward. MuleSoft is appropriate for large enterprise environments with high data volumes, complex transformation requirements, and existing MuleSoft licensing. A custom API build is appropriate when the integration involves systems without native Zapier or Make connectors, requires data transformation logic that exceeds what no-code platforms support reliably, or has error handling and retry requirements that go beyond what Zapier and Make provide natively. Ignited Nepal assesses the data volume, transformation complexity, error handling requirements, and existing platform costs before recommending an approach, and uses no-code tools where they are the right fit rather than recommending a custom build when Zapier or Make covers the need.

US businesses running Salesforce, QuickBooks, Stripe, Shopify, and Twilio as separate systems are not getting the compounding value that comes from making those systems aware of each other. Every manual export, every data transfer, and every cross-system status check is a cost that a connected API layer eliminates. Ignited Nepal starts with a diagnostic that maps what is currently manual, what the integration design should automate, and what the build scope and timeline look like before any work begins. If your team is doing data work that your software stack should be handling automatically, the diagnostic is the right next step.
