API integration services that outlast duct-taped connectors

We build custom API integrations when off-the-shelf connectors cannot handle your edge cases, volume, or data model.

Zapier and native connectors are great until they are not. Custom API work makes sense when mappings are non-obvious, retries matter, you need an audit trail, or the “simple sync” touches four systems and a spreadsheet.

What breaks today

The pain we hear on almost every intake

Connectors that break on field changes

Someone adds a dropdown in the CRM and three zaps silently stop firing.

Duplicate records and partial syncs

Without idempotency and clear keys, integrations create more cleanup work than they save.

No visibility when syncs fail

Teams discover integration gaps when invoices, leads, or inventory numbers are wrong—not when the job fails.

What we build

Focused deliverables—not a vague retainer

Bi-directional or event-driven syncs

Webhooks, polling, or queue-based jobs chosen for the systems involved—not because a template existed.

Mapping and transformation layer

Normalize messy vendor payloads into data your team can trust downstream.

Monitoring and replay tools

Failed events land in a review queue with enough context to fix and replay safely.

How we work

One workflow, one milestone, expand from proof

Document the systems and the truth source

Which tool owns customers, orders, inventory, or revenue—and what happens on conflict?

Ship one integration path end-to-end

Example: new HubSpot deal → QuickBooks invoice draft, or Stripe payment → internal fulfillment queue.

Harden for production

Rate limits, retries, alerting, and runbooks before expanding to the next system.

Questions

Straight answers

A focused two-system integration with error handling often starts between $2k–$20k for a first milestone, depending on API quality, auth complexity, and data cleanup.

Zapier wins on speed for simple, low-volume flows. Custom work wins on reliability, complex transforms, high volume, and when failures cannot be silent.

HubSpot, QuickBooks, Stripe, Google Workspace, Slack, and custom internal databases—often with a spreadsheet still in the loop somewhere.

Yes. APIs change, vendors add fields, and teams add workflows—we support production integrations with monitoring and iteration.
