Identify the billable unit in the current plan
Start with the provider’s current definition of a unit, included allowance and limits. Do not substitute the number of visible workflow boxes. Make, for example, distinguishes credits from operations and documents variable usage for some features. Keep the quoted plan, billing period and date alongside the model. A generic calculator cannot infer those terms from a vendor name.
Make: credits ↗ — Make distinguishes credits from operations; some features have variable credit use. Read the current plan and feature rules.
Model the path that actually runs
Count the trigger, actions, branches and repeated work under the selected provider’s rules. Make’s feature documentation distinguishes trigger use from actions performed on bundles, illustrating why the same diagram can consume different amounts with different input volumes. Avoid copying another workflow’s unit count without checking its path and feature mix.
Make: how features use credits ↗ — Different activities count differently, including triggers and work performed on bundles. The generic cost tool requires your own assumptions.
Separate the subscription from the operating total
Keep subscription, included allowance, overage, external APIs, storage, seats and maintenance as explicit line items where they apply. Our planner uses a flat base and linear overage with a user-supplied retry allowance. It cannot represent every tier, hard stop or annual commitment. Use a dated scenario for comparison, then replace assumptions with observed usage when a real trial is available.
Budget for accountable ownership
Include the work of reviewing failures, updating mappings, renewing services and transferring an asset. Keep per-publication costs attributable even when the same team maintains the infrastructure. A shared bill may need a documented allocation method; do not present that allocation as a direct vendor charge. Separate paid invoices from forecasts and unpriced credit usage in the financial record.
Keep these details together.
- Included allowance and overage rules
- External service costs
- Maintenance time and account ownership
