Write a count for each type
List the supported reactions and the quantity requested for each. A phrase such as balanced reactions leaves room for different interpretations. If the service selects the mix itself, describe that as supplier-defined rather than presenting it as an exact buyer-controlled allocation.
Check the input and minimums
Confirm whether separate service IDs, fields or orders are needed for the requested split. Individual minimum quantities may rule out a small custom configuration. Compare the total charge of a valid allocation instead of pricing the overall sum at one unrelated rate.
Review the correct breakdown
Keep the requested split with the order reference and observe the relevant reaction types where possible. An increase in the aggregate total does not prove the selected distribution arrived. If the breakdown is essential to the brief, agree on a practical evidence method beforehand.
Decision checklist
| Decision | What to check |
|---|---|
| Total | Sum of requested reactions |
| Distribution | Exact or supplier-defined |
| Input | Supported allocation method |
Worked example
For a hypothetical 90-reaction plan, 60 of one type and 30 of another differs from an unspecified 90-reaction mix. If the offer cannot accept the split, adjust the brief rather than assuming its mixed delivery will happen to match those amounts.
