Per–credit-customer selling charts at Rates → Customer Rates.
Rates → Customer Rates (/rates/customer) edits one credit customer’s chart. The same editor is on Manage credit customer → Ratechart.
Who can open it: users granted Customer Rates.
The Credit Customer block is required before the chart loads.
Same chart surface as My Rates / Common. Save Changes writes this customer only.
Copy this chart to other credit customers, or Copy Rates from Company to pull from a sibling org when org-sync is allowed.
If a booking path exists on the customer chart but no slab matches, the quote falls through to Common Rates.
