Sybil, what I meant was, you should schedule out the dates for later in the month (that is significant - do not schedule into the following month as you shall not be able to do them earlier).
For your immediate needs, do the shops that are currently scheduled for later, now. Re-arrange your schedule for the shops you wanted to do earlier and do them in place of the shops due later.
I know that it may sound confusing, but, if they are all shops for this particular MSC, that may be the simplest solution.
As for what shops that were performed and invoiced, here is what I do:
On my cheatsheet, I have a line that asks for the Invoice Date. After I have reported the shops, I then invoice them. After I have confirmed my receipts were uploaded, I save the web page in an invoice folder on my computer and on my cheatsheet, I write down the date of the invoice.
When I receive my check from the MSC, I review all of the visit account numbers on the accompanying payment detail. I then cross off each visit number and set aside that cheatsheet (with the receipts stapled to it, I might add). When done, all of the cheatsheets and receipts stapled to them are filed with the payment detail as hard copies.
I then know which visits in which I shall expect future payment.
If i am not paid for those visits in the next pay period, I call and ask for Frances in accounting.
BTW, I heard something about "colder than a well digger's behind". I can imagine what it means, but I do not understand why.
I asked my husband and he just rolled his eyes.
