How do I start recording supplier credit limits?

1) Open Accounts → Credit & performance (/accounts/credit-control). 2) Add account for each credit line a supplier extends to one company — limit, terms, credit contact email, guarantor — or Import from template. 3) Link each line to its supplier record where the banner suggests a match, so Used can be worked out. 4) Ask suppliers to confirm limits (everyone, everyone shown, over limit or on hold, or one line); answers land under Supplier updates and apply at once with Undo. 5) Watch the status: OK, Near limit, Over limit, On hold. Under Available, the button adds that supplier's bills to the open payment run to get room back.
