English to German Marketing Textiles / Clothing / Fashion

We currently make deliveries to stores using A and B ***periods***, which means that stock can arrive anytime within a two week ***period*** and is supplied from various Distribution Centres. We also allocate stock by ***period***, which means that during times of high replenishment demand we have to allocate a minimum of 14 days.
At such times this leads to daily manipulation of systems to ensure the best stores are kept serviced and also large arrears are created at the beginning of the next ***period***.

Ist hier immer eine zeitliche Periode im Sinne von Zeitspanne gemeint oder kann period zum Beispiel im ersten Satz auch als Saison (also Ware aus der A- und B-Saison)übersetzt werden?

Vielen Dank für jeden Tipp!
