Usage tips
Word structure
The word consists of 'Stamm' and 'Kunde' (customer). Here, 'Stamm' means something like 'firmly belonging' or 'core'. So a 'Stammkunde' (regular customer) is a customer who belongs to the fixed core of a business.
EXAMPLE
Der Bäcker begrüßt jeden Morgen seine Stammkunden mit Namen.
The baker greets his regular customers by name every morning.
Typical context
The term is usually used for businesses or service providers with personal contact, such as cafés, small shops, hairdressers, or restaurants. It is less common with large, anonymous supermarket chains.
EXAMPLE
In meinem Lieblingscafé bin ich seit Jahren Stammkunde.
I have been a regular customer at my favorite café for years.
Word family
The prefix 'Stamm-' is often used to express regularity or a fixed sense of belonging. Similar formations include, for example, 'der Stammgast' (regular guest, in a pub/restaurant) or 'die Stammkneipe' (the pub one regularly goes to).
EXAMPLE
Er geht jeden Freitag in seine Stammkneipe, um Freunde zu treffen.
He goes to his regular pub every Friday to meet friends.

Stammkunde vs Kunde
customer
'Kunde' and 'Stammkunde' are closely related, but they are not the same. 'Kunde' is anyone who buys something or uses a service. 'Stammkunde' is a special kind of customer: this person comes regularly and has been going to the same shop or provider for a long time. The words can be confused because every 'Stammkunde' is a 'Kunde'. But a 'Kunde' may also come only once. When the regular relationship is important, you say 'Stammkunde'.
Stammkunde
Dem Stammkunden legt die Bäckerin jeden Morgen sein Lieblingsbrot zurück.
The baker sets aside the regular customer's favorite bread for him every morning.
Kunde
Ein Kunde kauft im Supermarkt nur eine Flasche Wasser.
A customer buys only one bottle of water at the supermarket.
