I compared native vs middleware costs for 55 B2B integrations. Middleware wins on paper 13 times — and that's the trap

Description and use

The study compares native connectors versus middleware for 55 B2B integrations. Native is cheaper in 25 cases; middleware appears cheaper in 13 but sacrifices 2‑way sync and adds dependency risk. 35 integrations hide forced tier upgrades that inflate budgets.

Problem

Organizations lack transparent cost comparisons between native connectors and middleware for B2B integrations, leading to hidden upgrade fees and misestimated budgets.

Outcome

The study shows native connectors are cheaper in 25/55 cases; middleware appears cheaper in 13/55 but often sacrifices 2‑way sync, adds third‑party risk, and may exceed free operation limits. Hidden forced tier upgrades affect 35/55 pairs, underscoring the need for transparent cost analysis.

Workflow

• 1. Identify the native connector and required plan tier for each integration pair.
• 2. Calculate the native cost for a 10‑seat team using vendor pricing pages.
• 3. Identify the cheapest API‑capable tiers for each app and add a $9/month middleware fee (Make).
• 4. Compare native vs middleware costs side‑by‑side.
• 5. Evaluate trade‑offs: sync direction, third‑party dependency, operation volume against middleware free tier.
• 6. Decide based on rule‑of‑thumb: use native if tiers already paid, otherwise evaluate middleware only if 1‑way sync suffices and volume fits.
• 7. Use the calculator on stackcostmatrix.com to adjust seat counts.
• 8. Update the open dataset on GitHub if pricing changes.

Evidence

Every "connect X to Y" page shows you the happy path. Almost none of them tell you which plan tier the native connector actually requires, or what happens to your bill when you route the same integration through middleware instead.

In 25 of the 55 pairs, the native path costs less than the middleware path, full stop.

Source

In 13 pairs, middleware wins on the sticker price — and every one of those wins comes from skipping a forced tier upgrade.

Source

35 of the 55 pair pages mention a forced tier upgrade: the tier the native connector requires is higher than the tier you would buy for the app on its own.

Source

If the native connector runs on tiers you already pay for, take native. It is usually cheaper and it syncs both ways.
