Integrations 101: making your systems finally talk to each other
Somewhere in your business, right now, a person is copying information from one screen into another. Orders from email into the order system; invoices from the order system into accounting; tracking numbers back into email. Each of those hops is an integration that doesn’t exist yet — and building it is usually the highest-return software project on your menu. Here’s how integrations actually work, minus the jargon.
What an integration really is
Most modern software exposes an API — a doorway other software can use to read and write its data. An integration is a small, reliable program standing between two doorways: when a paid order appears in system A, create the invoice in system B; when inventory changes in the warehouse, update the website. No screens, no logins — it just runs, thousands of times, without typos.
The three flavors, cheapest first
Native connections — sometimes your two tools already integrate; it’s a settings page and an afternoon. Always check first. Connector platforms (Zapier and friends) — good for simple, low-volume “when this, do that” flows; costs grow with volume and complexity. Custom integration — built for your exact rules, volumes and edge cases; the right call when the data flow is core to operations, like the live inventory and order-status connections behind the customer portal we built for a parts distributor.
Where integration projects go wrong
Almost never in the plumbing — in the assumptions. Which system is the source of truth when the two disagree? What happens when a record is missing, duplicated, or half-typed? What should a human see when something fails at 2 a.m.? Good integrations are mostly answers to those questions, with code attached. That’s why ours start with a short discovery pass over your actual data before anything is built.
The honest test: list every place a person re-types data between two systems. Each row on that list is an integration with a measurable payback — usually weeks, not years.
Start with one
You don’t need an “integration strategy.” Pick the hop that costs the most hours or causes the most errors, connect it, and let the result argue for the next one. The errors stop the day it ships — that part never gets old.
