Whether your company is missing agreed supplier bonuses or rebates becomes clear through a systematic target-actual comparison: is every agreed condition, every volume tier and every rebate actually settled and credited? Without this regular reconciliation, entitlements quietly slip through unnoticed. The clearest warning signs are purely Excel-based administration, no monitoring of tier targets, media breaks between purchasing, ERP and settlement, and a conditions check that only happens at year-end. Closing these gaps makes lost earnings visible before entitlements expire.

The most common warning signs of missed conditions

Missed bonuses are rarely the result of a single error, but of structural gaps in the conditions process. The overview below shows how to identify elevated risk:

Warning sign	What lies behind it	Check indicator
Administration in Excel only	No automatic tier and deadline monitoring, high error rate with manual upkeep	Are conditions maintained by hand in spreadsheets?
No in-year target-actual comparison	Deviations between agreement and settlement surface late or not at all	When was “agreed” last compared against “settled”?
Tier and target bonuses without monitoring	Narrowly missed or reached tiers go unused	Does purchasing know how close each supplier is to the next tier?
Media breaks between systems	Data is lost in the handover purchasing → ERP → settlement	Do revenue and conditions data flow automatically?
Unclear responsibilities across multiple entities	Centrally negotiated conditions are not applied to all sites	Are group-wide conditions recorded in consolidated form?
No audit-proof documentation	Valid entitlements cannot be substantiated to suppliers	Is every agreement fully traceable?

Check in three steps whether bonuses are slipping away

Step 1 – Run a target-actual comparison: Compare the agreed conditions against the amounts actually settled. Every difference is a candidate for a missed or miscalculated entitlement. Start with your highest-revenue suppliers and the most complex agreements, because that is where the financial risk is greatest.

Step 2 – Monitor tier and target achievement: Check throughout the year how close each supplier is to the next bonus tier or target agreement. This lets you catch narrowly missed tiers in time, steer orders deliberately, and secure liquidity through in-year settlement instead of tying up bonus payments until year-end.

Step 3 – Digitalise processes and remove media breaks: Replace manual Excel upkeep with structured, automated capture that connects directly to your ERP and finance system. Only an end-to-end data flow makes deviations reliably visible and creates an audit-proof basis for asserting entitlements.

How proLogistik makes unused conditions visible with BONSAI

This is exactly where BONSAI, the conditions management solution from the proLogistik Group, comes in. It captures all agreements in a structured way, calculates and monitors tiers and targets automatically, and reconciles target with actual values. Settlements are produced audit-proof and in line with GoBD requirements, with every step fully documented. Thanks to seamless integration into existing ERP and finance systems (such as SAP, DATEV or SEPA), media breaks disappear, and the integrated supplier portal enables structured exchange of reports and agreements. This makes missed bonuses visible before entitlements expire – from preparing annual negotiations to automated settlement.

FAQ – Frequently asked questions about missed supplier bonuses

How do I know if we are missing supplier bonuses?

The clearest sign is the absence of a systematic comparison between agreed and actually settled conditions. If no one regularly checks whether every agreed bonus, tier and rebate has actually been credited, entitlements slip through unnoticed. Further warning signs are purely Excel-based administration, missing reminders for tier thresholds, and media breaks between purchasing, ERP and settlement.

What are the most common causes of missed rebates?

Typical causes are unmonitored tier and target agreements, manual transfer errors in Excel, unclear responsibilities across multiple entities or sites, and a lack of deadline control. Complex special agreements and retroactive condition changes are also easily lost without structured capture.

How often should a target-actual comparison of conditions be carried out?

A target-actual comparison should not wait until year-end but happen throughout the year and regularly – ideally monthly or quarterly. This allows deviations to be spotted early, tier targets to be steered deliberately, and liquidity to be secured through in-year bonus settlement.

Why is Excel risky for conditions management?

Excel offers no automatic deadline and tier monitoring, no audit-proof documentation and no direct connection to ERP or finance systems. As the number of suppliers and agreements grows, so does the risk of transfer errors, forgotten entitlements and a lack of traceability.

How does conditions management software like BONSAI help?

A specialised solution like BONSAI from proLogistik captures all agreements in a structured way, calculates and monitors tiers and targets automatically, and reconciles target against actual values. It produces audit-proof settlements, documents all processes in line with GoBD, and integrates seamlessly into existing ERP and finance systems. This makes missed bonuses visible before entitlements expire.

Are retroactive claims possible for forgotten bonuses?

Whether and for how long retroactive claims are possible depends on the specific agreement, the contractual deadlines and the statute of limitations. What is decisive is complete, traceable documentation of the agreed conditions – only this allows valid entitlements to be substantiated and asserted towards suppliers.

Conclusion: Transparency protects your earnings

Missed supplier bonuses and rebates are almost always a symptom of missing transparency – not of poor negotiations. A regular target-actual comparison, in-year monitoring of tiers and the removal of media breaks make unused entitlements visible. Get a transparent overview of your conditions now: learn more about BONSAI conditions management or talk to an expert from the proLogistik Group.
