For both CAPD and APD you have do to a stock take once a month or once every other week – depending on how often your deliveries are.
I found that doing a stock take can take ages, especially when you move to APD as there is so much more stuff to account for.
However I found that by writing on each box the number of that idem left together with the date (and keeping that info up to date) made the whole process much quick.
So instead of counting 43 mini caps, I can just read on the back that on 23rd June there was 43 caps – quick and easy!
Also, keep a record of all your counting, as well as the deliver sheets and the stock list that Baxter gives you. It makes correcting any errors much easier.
