API & integrations

Most ERP and CRM projects fail not at the launch, but six months in, when one system stops syncing with another and nobody notices for a week. We build the glue with that exact failure mode in mind: observability first, idempotency by default, dead-letter handling for the cases nobody planned for.

We've moved invoices between Tally and a custom ERP, contacts between a legacy CRM and a fresh one, orders between Razorpay and SAP Business One, and WhatsApp messages between a customer chatbot and a CRM ticket queue. The pattern is the same: make the seams readable.

Inside the build

What's actually included.

Idempotent webhook handlers

Every inbound event has a unique key. Retries don't create duplicate invoices, retries don't fire your customer's WhatsApp twice.

Retry queues + dead-letter

Failed jobs go to a queue with exponential backoff, then to a dead-letter table you can inspect. No silent data loss, no 'I thought the integration was working' meetings.

Replayability

Every inbound message is captured raw. You can replay a single event, a date range, or the whole feed against a new handler, useful for fixing data and for migrations.

Human-readable logs

Structured logs with the entity ID, the action, the source, and (when an error fires) the offending payload. Searchable in BetterStack or your provider, not a stream of JSON nobody reads.

Health endpoint + alerts

Each integration exposes a /health endpoint with last-success-at, queue depth, and error count. Slack or email alert when a metric crosses your threshold.

Connector library

Pre-built connectors for Tally Prime, SAP B1, Razorpay, Microsoft Graph, WhatsApp Cloud API, GSTN, HubSpot, and Google Workspace. New connectors typically take 1–2 weeks each.

Who this is for

Teams running 3+ systems that should be talking to each other and aren't: Tally + a custom app, SAP + a CRM, WhatsApp Business + a helpdesk, Razorpay + accounting. Also good when an existing integration is breaking weekly and you've lost confidence in what's actually syncing.

How we work

Three stages, no surprises.

01

Discovery

A 30-minute call to map the workflow that's actually broken. We walk you through what we'd build, what we wouldn't, and a written scope with timeline and milestones.

02

Weekly sprints

Working prototype by week 2, MVP in staging by week 4–6. Friday demo every week: you see it before it's done, not after. Slack channel + Linear / Jira board you have access to.

03

Handover + retainer

Go-live with a written playbook, training material per role, and a 30-day office-hours window. Most clients move onto a maintenance retainer for the work that comes after.
