Payment terms negotiation: net 30, net 60, and the real cost of early pay — Guide pratique pour les restaurants
Une méthode concrète, fondée sur les factures, les chiffres et des contrôles simples.
A restaurant decision is only as reliable as its source and assumptions. A 2% discount in 10 days versus day 30 is about 36.7% simple annualized value, but only when cash is available. Write the baseline, show the formula, and separate an observed result from an illustrative estimate. A good guide gives the manager a practical review path, a threshold for action, and a date to check whether the correction worked.
What the data can and cannot tell you
- Net 30 means payment is due 30 days after the agreed invoice date; confirm the supplier’s definition.
- A 2% discount in 10 days is roughly 36.7% simple annualized return versus paying on day 30.
- Model payroll, rent, tax, and seasonal cash needs before committing to early payment.
- Offer a trial or partial-category change and document the exact start date.
A worked example
A restaurant compares a dated source with an expected result and finds a gap. These numbers show the method only; they are not a verified customer case.
| Invoice | €10,000 | Due on day 30 without discount |
|---|---|---|
| 2% in 10 | €200 saving | Only if cash is available |
| Annualized value | ~36.7% simple | 2% ÷ 20 days × 365 |
| Decision | Model liquidity | Avoid overdraft disguised as saving |
Use the calculation only when the source, unit, and exception log are visible. Treat it as illustrative until your own records confirm it.
A repeatable process
- 1Define the question. Write the decision, source, unit, time window, and threshold before opening the spreadsheet.
- 2Reconcile inputs. Match identifiers, quantities, dates, credits, and exceptions. Flag missing evidence instead of guessing.
- 3Calculate the gap. Show formula, baseline, observed result, and illustrative impact. Keep price separate from waste or process variance.
- 4Review and act. Have a manager review material exceptions, agree one action, and set a date to measure it.
FAQ
- What is the most common mistake?
- Comparing numbers that look similar but use different units, dates, specifications, or commercial terms.
- How precise should the result be?
- Precise enough to support a decision, not more precise than the source. Preserve the underlying invoice, image, or count.
- When should a person review it?
- Whenever confidence is low, the amount is material, the item is unusual, or an exception changes the conclusion.
- Are the savings figures guaranteed?
- No. All figures in this guide are illustrative. Validate the formula and opportunity against your own records.
