ALL SYSTEMS OPERATIONAL

Systems Integration in NYC & Northern NJ

Most operating businesses have eight to fifteen systems that nobody intentionally chose, all loosely connected with manual exports, copy-paste, and the occasional Zapier. We build the integrations that turn that into one coherent operation — connecting accounting, CRM, ERP, ticketing, e-commerce, and the spreadsheets that are still load-bearing into a system that works at three o'clock in the morning, not just on demo day.

§ 01 — What We Build

What we actually build.

01

ERP & Accounting Integrations

QuickBooks, NetSuite, Sage, Microsoft Dynamics. Order-to-cash, procure-to-pay, GL synchronization. Monthly close that doesn't require manual reconciliation.

02

CRM & Sales Stack Integrations

Salesforce, HubSpot, Zoho — connected to the systems that hold the truth (orders, invoices, support tickets) so your sales team isn't operating on stale data.

03

EDI & B2B Trading-Partner Integrations

EDI 850/810/856 with retailers, distributors, and freight providers. Onboarding, mapping, certification, and ongoing operations. Onboarding new partners without it being a months-long project.

04

Custom API & Webhook Architectures

When the integration doesn't exist off-the-shelf — or the off-the-shelf one is unreliable — we build the bridge. Idempotent, retry-able, observable, and documented.

§ 02 — How We Work

The process.

  1. 01

    Map the Flow

    Diagram of the actual flow of work and data between your systems today, including the manual steps. Most projects find at least one place where the manual workaround should become permanent and one where it absolutely shouldn't.

  2. 02

    Source of Truth

    For each business entity (customer, order, invoice, employee), agree on which system is authoritative and which are downstream. Half of integration failures are caused by this not being decided.

  3. 03

    Build & Test

    Integrations built with idempotency, retries, dead-letter queues, and audit logs. Tested with real-world failure modes — partner downtime, schema drift, duplicate events.

  4. 04

    Operate & Monitor

    Dashboards on integration health, automated alerting, and a runbook for the operations team. Integrations that fail loudly, not silently.

§ 03 — Local Delivery

NYC & Northern NJ in person.

Integration work depends on understanding workflows that mostly live in people's heads. We're headquartered in NYC and run discovery onsite across the five boroughs — at the operations team's actual desks, watching the real process — which routinely surfaces business rules that nobody documented. For Northern New Jersey clients we schedule discovery on the days we're in-state (twice a week) and travel for major cutovers regardless of day. The build and operations work is largely remote thereafter, with onsite presence for major cutovers (e.g., bringing a new ERP live).

§ 04 — Tech & Tooling

The stack.

  • TypeScript / Python
  • Postgres
  • Inngest / Temporal
  • Workato / Tray
  • QuickBooks API
  • NetSuite SuiteTalk
  • Salesforce / HubSpot APIs
  • AS2 / SFTP / EDI

Custom integrations in TypeScript or Python with Postgres for state and Inngest or Temporal for durable execution. iPaaS platforms (Workato, Tray) for standard SaaS-to-SaaS connections where the maintenance burden of custom code isn't justified. EDI via AS2 or SFTP using a real EDI translator, not regex.

§ 05 — Who This Is For

Who we work with.

Distributors and light manufacturers

ERP plus a handful of e-commerce, EDI, and 3PL connections that all need to stay in sync. The cost of a missed order or a duplicate invoice is real money.

Multi-system SMBs

Operating businesses with separate accounting, CRM, billing, and operational systems — where the monthly close and the weekly forecast are both manual processes today.

Companies migrating ERPs

Coming off QuickBooks, moving to NetSuite or Sage. Or replacing a legacy ERP entirely. The integration architecture is half the project.

§ 06 — FAQ

Common questions.

Should we use Zapier, an iPaaS, or custom integration?
Zapier for low-volume, low-stakes flows. iPaaS (Workato, Tray, Boomi) for standard connections at moderate volume. Custom code when the volume, reliability, or business logic demands it. Most production businesses end up with a mix; we'll write down which is which and why.
How do you handle EDI?
We use a real EDI translator (commercial, not roll-your-own) and treat partner certification as part of the engagement. We've onboarded EDI partners for retailers, freight, and healthcare scenarios.
What about NetSuite?
NetSuite integrations are a meaningful share of our integration practice. SuiteTalk REST and SOAP, SuiteScript when needed, plus the standard pattern of pulling NetSuite into a warehouse rather than querying it directly for analytics.
Can you take over an existing integration that's flaky?
Yes. Many of our integration engagements start as 'this is broken and we don't trust it.' The first deliverable is usually an honest assessment of whether to fix or replace.
Do you do this onsite?
Discovery and ERP cutover work, yes — onsite across the five boroughs of NYC same-week, and in Northern New Jersey on the days we're routinely in-state. Build and operate is remote.
