ERPNext Integration Partner
ERPNext Integration Services
PrimoERP builds ERPNext integrations that stay running—connecting your ERP to ecommerce platforms, payment gateways, CRMs, accounting systems, and custom applications with production-grade reliability.
We engineer integrations for the failure modes most providers ignore: API rate limits, network timeouts, data drift, schema changes, and silent sync failures. Every integration includes retry logic, idempotency handling, reconciliation checks, and observability from day one.
Why ERPNext Integrations Break in Production
Most integrations work in demos. They fail in production—under real transaction volumes, intermittent network conditions, and external API changes. The symptoms are familiar: duplicate orders, missing payments, inventory mismatches, and sync jobs that fail silently for days before anyone notices.
These failures aren't random. They're predictable consequences of integrations built without error handling, retry logic, or observability. A payment webhook that doesn't verify idempotency creates duplicate invoices. An ecommerce sync without reconciliation drifts out of alignment. An integration without logging leaves you guessing when things break.
PrimoERP builds integrations to handle these realities. We design for failure, implement defensive patterns, and instrument everything so problems are detected and diagnosed quickly.
- ✕Webhooks processed without idempotency checks, creating duplicate records
- ✕API calls without retry logic, losing data during temporary outages
- ✕Sync jobs without reconciliation, drifting silently out of alignment
- ✕No dead-letter handling for failed messages—data lost permanently
- ✕Missing logs and alerts—failures discovered days or weeks later
- ✕Hardcoded mappings that break when external systems update their schemas
- ✕Rate limit violations causing cascading failures and API lockouts
Our Approach
A Structured Integration Methodology
Every PrimoERP integration follows a phased methodology designed to surface requirements, design for edge cases, and validate behavior before production deployment. We don't start coding until the integration contract is defined. We don't deploy until staging tests pass.
This discipline prevents the rework cycles and production incidents that plague ad-hoc integrations.
Phase 1: Discovery & Scoping
We map data flows, identify sync requirements (direction, frequency, volume), document external API capabilities and constraints, and define success criteria. Deliverable: Integration Requirements Document with data mapping specifications and sync architecture.
Phase 2: Architecture Design
We design the integration pattern (direct API, webhook, middleware), define retry policies, specify idempotency strategies, and plan for rate limits. Deliverable: Technical Design Document with sequence diagrams, error handling matrix, and API contracts.
Phase 3: Development
Integration code is built in a development environment with comprehensive logging, error handling, and test coverage. We follow Frappe patterns for background jobs, scheduled tasks, and webhook handlers. Code is version-controlled with meaningful commits.
Phase 4: Testing & Validation
We test against staging environments with realistic data volumes. Tests cover happy paths, error conditions, rate limit behavior, and recovery scenarios. Reconciliation reports verify data integrity. Deliverable: Test results and staging sign-off.
Phase 5: Deployment & Hypercare
Production deployment follows a runbook with rollback procedures. Initial sync is monitored closely. Hypercare period provides rapid response for issues discovered under production load. Deliverable: Live integration with monitoring dashboards active.
What We Build
Integration Capabilities
PrimoERP provides full-stack integration engineering—from simple REST API calls to complex multi-system orchestration with middleware layers. Every integration is built with production reliability as the primary design constraint.
REST API Integrations
Direct integration with external REST APIs using ERPNext's request framework. Authentication handling (API keys, OAuth, tokens), request/response transformation, and error parsing. Pagination support for bulk data retrieval.
Webhook Handlers
Inbound webhook endpoints for receiving events from external systems. Signature verification, payload validation, idempotency checks, and async processing via Frappe background jobs. Retry-safe with duplicate detection.
Scheduled Sync Jobs
Frappe scheduler-based sync jobs for batch operations—hourly, daily, or custom intervals. Incremental sync using timestamps or change tokens. Conflict detection and resolution logic for two-way sync scenarios.
Middleware & Queue Workers
For complex integrations involving multiple systems, message transformation, or high throughput, we implement lightweight middleware layers. Message queues with dead-letter handling, retry policies, and backpressure management.
Data Mapping & Transformation
Field mapping between ERPNext doctypes and external system schemas. Data type conversion, unit transformation, lookup resolution, and default value handling. Mapping configurations stored separately from code for maintainability.
Two-Way Sync & Conflict Resolution
Bi-directional sync with configurable conflict resolution—last-write-wins, source-of-truth designation, or manual review queues. Change detection using timestamps, version numbers, or hash comparison.
Systems We Connect
Commonly Integrated Platforms
We've built ERPNext integrations with platforms across ecommerce, payments, accounting, CRM, logistics, and business intelligence. The specific integration approach varies based on each platform's API capabilities, webhook support, and data model.
Ecommerce Platforms
Shopify and WooCommerce integrations for order import, inventory sync, product catalog management, and fulfillment status updates. Support for multi-store configurations and marketplace connectors.
Payment Gateways
Razorpay, Stripe, and PayPal integrations for payment status sync, refund processing, subscription management, and reconciliation. Webhook handling for real-time payment events with idempotency protection.
Accounting Systems
Tally integration for voucher export, ledger sync, and GST compliance workflows. QuickBooks and Zoho Books integrations for chart of accounts mapping, invoice sync, and payment reconciliation.
CRM Systems
HubSpot and Zoho CRM integrations for lead/contact sync, deal pipeline updates, and activity logging. Bi-directional sync with conflict resolution for shared customer records.
Shipping & Logistics
Integration with shipping providers for rate lookups, label generation, tracking updates, and delivery confirmation. Support for multi-carrier routing and automated carrier selection rules.
BI & Data Warehousing
Scheduled data exports for Power BI, custom data warehouses, and analytics platforms. Incremental export support, schema documentation, and data freshness tracking.
Data Integrity
Reconciliation, Validation, and Audit Trails
Data integrity is the foundation of reliable integrations. A sync that runs without errors but produces incorrect data is worse than a sync that fails loudly—because the problem compounds silently until it's discovered in financial reports or customer complaints.
PrimoERP builds reconciliation into every integration. We don't just move data—we verify that source and target match, flag discrepancies, and provide audit trails for transparency and debugging.
- ✓Record count validation: verify source count matches target after each sync cycle
- ✓Checksum and total verification: compare financial totals, quantity sums, and hash values
- ✓Discrepancy detection: automatic flagging of records that don't match expected values
- ✓Audit logging: every sync operation logged with timestamps, record IDs, and outcomes
- ✓Reconciliation dashboards: visual reports showing sync status, error counts, and drift metrics
- ✓Historical comparison: track data integrity over time, detect gradual drift patterns
Built for Failure
Error Handling, Retries, and Recovery
Production integrations must assume failure: network timeouts, rate limits, API errors, malformed responses, and transient outages. The question isn't whether failures will occur—it's whether the integration handles them gracefully or loses data.
PrimoERP designs integrations with explicit failure handling at every layer. We classify errors, implement appropriate retry strategies, preserve failed messages for recovery, and alert operators when intervention is needed.
- ↻Error classification: distinguish transient failures (retry) from permanent failures (alert)
- ↻Exponential backoff: retry policies that respect rate limits and avoid thundering herd
- ↻Idempotency keys: ensure retried operations don't create duplicates
- ↻Dead-letter queues: failed messages preserved for analysis and manual replay
- ↻Circuit breakers: prevent cascading failures when external systems are down
- ↻Graceful degradation: continue processing unaffected records when individual items fail
- ↻Alerting thresholds: notify operators when error rates exceed acceptable levels
Monitoring & Support
Observability and Ongoing Support
An integration without monitoring is a liability. You need visibility into sync status, error rates, latency, and data freshness—not just when problems occur, but continuously, so you can detect degradation before it becomes an outage.
PrimoERP instruments every integration for observability and provides ongoing support options to keep integrations running smoothly as your systems evolve.
Logging & Metrics
Structured logging for every integration operation—request/response pairs, processing time, error details, and record identifiers. Metrics for sync frequency, volume, error rates, and latency trends.
Dashboards & Reporting
Integration health dashboards showing sync status, last successful run, pending items, and error counts. Scheduled reports for reconciliation results and data integrity checks.
Alerting & Escalation
Configurable alerts for error thresholds, sync failures, and data discrepancies. Escalation paths for critical issues. Integration with your existing alerting tools (email, Slack, PagerDuty).
Hypercare Period
Post-launch hypercare with dedicated support for the first 2–4 weeks. Rapid response for production issues, performance tuning, and adjustment to real-world traffic patterns.
Ongoing Support Packages
Maintenance and support packages for production integrations—bug fixes, minor enhancements, API version updates, and incident response. SLAs based on severity classification.
Security
Secure Integration Practices
Integrations handle sensitive data—customer records, financial transactions, inventory values. Security isn’t an afterthought; it’s designed into every integration from authentication to data handling to access control.
- 🔒Authentication best practices: OAuth flows, API key rotation, token refresh handling
- 🔒Secrets management: credentials stored securely, never hardcoded, rotatable without code changes
- 🔒Transport security: TLS for all external API calls, certificate validation enforced
- 🔒Least privilege: integration accounts have minimum permissions required for their function
- 🔒PII handling: sensitive fields identified, logged appropriately (masked or excluded), retention policies enforced
- 🔒Input validation: all incoming webhook payloads validated before processing
- 🔒Access control: integration endpoints protected, audit logged, rate limited
Upgrade-Safe Architecture
Integrations That Survive ERPNext Updates
ERPNext releases regular updates—bug fixes, security patches, new features. Integrations built with core modifications or undocumented APIs break unpredictably during upgrades, creating emergency rework.
PrimoERP builds integrations using Frappe's official extension mechanisms: custom apps, hooks, and documented APIs. We version integration contracts, test against new releases in staging, and design for forward compatibility.
- ✓Custom app architecture: integration code packaged as Frappe apps, isolated from core
- ✓Documented API usage: rely on stable, documented ERPNext/Frappe APIs only
- ✓Version pinning: external API versions tracked, upgrade paths planned
- ✓Staging validation: integrations tested against new ERPNext versions before production upgrade
- ✓Integration contracts: data mapping and API contracts documented, versioned, and maintained
- ✓Deprecation monitoring: track ERPNext changelog for breaking changes affecting integrations

Why PrimoERP
What Sets Our Integration Practice Apart
There are many developers who can connect two systems with an API call. Fewer build integrations that stay running under production conditions, handle failures gracefully, and remain maintainable as systems evolve. That's the difference PrimoERP delivers.
Production-Grade Engineering
We design for failure from the start—retry logic, idempotency, dead-letter handling, and graceful degradation. Not demo-quality code that breaks under load.
Observability by Default
Every integration includes logging, metrics, dashboards, and alerting. You see what’s happening, not just when things break.
Data Integrity Focus
Reconciliation checks, validation scripts, and audit trails ensure data accuracy—not just data movement.
Upgrade-Safe Architecture
Integrations built on Frappe's extension patterns survive ERPNext updates without emergency rework.
Full ERPNext Context
As a full-service ERPNext partner, we understand how integrations fit into implementations, customizations, and data migrations. We don't build in isolation.
Ongoing Partnership
We don't disappear after go-live. Hypercare, support packages, and maintenance keep integrations running as your systems evolve.
