Vendor concentration risk: identify the suppliers your business cannot easily replace

A small number of vendors can control critical software, inventory, logistics, contractors, or infrastructure. Finance can make that dependence visible before a disruption becomes a cash problem.

Spend size and operational criticality are different

The largest vendor by dollars may be easy to replace, while a smaller software or logistics provider can be essential to daily operations. A useful analysis considers both spend and switching difficulty.

Start with the accounts-payable ledger and then add operational context.

Build a top-vendor view

For material suppliers, track annual spend, payment terms, renewal dates, contract minimums, prepaid balances, deposits, termination terms, alternatives, and the owner of the relationship.

Flag related-party vendors separately so the reporting remains transparent.

Model cash effects of disruption

A vendor failure can require expedited purchases, deposits with a replacement, duplicate subscriptions during migration, or inventory prepayments. Those are cash events even before revenue is affected.

Include critical vendor scenarios in short-term cash planning where the exposure is meaningful.

Use renewals as a finance checkpoint

Before a major renewal, compare actual usage, price changes, service quality, contract length, and available alternatives. Finance can bring the historical spend while the operating owner evaluates business value.

That creates a better decision than approving the same invoice every year by habit.
