What it is
A supplier/client catalog is a supplier-managed catalog visible only to your organization, holding the prices you negotiated. The supplier keeps the items and prices current; you keep the exclusivity of the terms.
It sits between a hosted catalog (your data, your maintenance) and a global catalog (their data, public prices): their maintenance, your prices.
The benefits
This is the catalog type with the most direct line to the P&L.
- Negotiated prices become the default buying route — the single strongest defence against maverick buying
- Price changes arrive from the supplier, so the list never goes stale in your system
- Invoiced price can be matched against agreed price every month, which is how savings actually get verified
- Contract compliance becomes measurable instead of assumed
- No catalog maintenance work for your team on contracted categories
Set it up in the same conversation as the negotiation
The right moment to ask a supplier to load a catalog is while you are agreeing the price, not three months later. Make catalog loading part of the award, alongside payment terms and lead time.
Suppliers usually agree, because a catalog raises their share of your spend without any selling effort.
- Add catalog loading and maintenance to the award conditions
- Agree who updates prices and how much notice a change requires
- Define the item scope — a partial catalog invites off-catalog buying
- Set a monthly check of invoiced price against catalog price
Then enforce it gently
Once a category is covered, off-catalog purchases in that category should require a reason. Not a block — a reason. The exceptions tell you where the catalog is incomplete, which is more useful than the compliance number.
