You have three tools you already pay for. You manually cross-reference them each month. The temptation is to "make an app." Sometimes the missing piece is a cable. Sometimes the cable doesn't exist because the process doesn't fit into any of the three.
Integrate when
All three systems do their job. The problem is the transfer between them: copying a customer, an order, a status. The data already exists somewhere. No one is rewriting it. It just doesn't travel.
The rule is stable. "If the budget is accepted, it creates the work." That's a bridge. It's not a product.
You can say which field is outputting and which field is inputting. If you can't, you're not ready to integrate. You're ready to sit down and write the flow.
Build when
The problem is the work, not the transportation. Budget your way. Plan by your own rules. A closure that none of the three know how to handle. There, integration just moves a temporary fix from one place to another.
One of the three is the real one, and the others are just theater. If the official number is just a temporary measure, don't include that measure. Replace it. That's the other article: leave the spreadsheet.
No one can name the system that's in charge. Integrating three sources without a single owner leaves you with three truths. First, choose which one is in charge. Then, the cable.
A short test
Write on one line: "When X happens at A, then Y must exist at B." If that line represents the month, integrate. If the month represents everything that happens within A, construct A.
Don't do both at the same time "to save money." The bridge and the new part are two separate projects. Two separate budgets. If you combine them, you're back to an open budget.
What this is not
This isn't a connector catalog. It's not a list of brands. If A and B have an official track and the ruler fits on a line, use it. If the track doesn't exist or the ruler doesn't fit, that's the key: either change the ruler or build the part.
After
If the bridge is the work, the commission remains the same and the scope fits within that framework. If the new piece is the work, the commission is... custom software. This page only separates the cable from the tool.
