I would suggest to you to set up the credit card in Sage and choose it when entering payables. It will post directly to the credit card rather than payables. You will choose the vendor, amount, and account, as usual, just enter the payment method as the credit card.
Not entering them individually means you will have a rough time doing bank recs and you will have to do some math to get them done.
You can keep all the receipts in an envelope and post them as one entry at the end of each month, but you will not be able to manage cash flow easily because you will not have updated your books for a month. These small items sometimes add up to hundreds of dollars.
You can fill out a spreadsheet of all the receipts and post them as one entry at the end of each month. This will maintain a total you can subtract from your bank balance each time you need to do cash flow analysis and give you one entry at the end of each month. If you keep an invoice total on the spreadsheet as well, you can use it to check off the balances as they show up on the bank statement when you do reconciliations.
Generally, I've found it more work to find ways to not post them individually than to just post them as you get them.
Agate's idea of setting up a credit card is a good one also. You can set it up as DP (Direct Payment) and use the bank account in the setup, That way you can just pick the payment method from the payment method dropdown. If you do post them individually, you can keep the original invoices posted under the original vendor name so you can find them easier afterward.

U can always pay ahead of time. Only thing you have no control over is if the vendor changes the payment due date. So u have to be vigilant lest you incur late payment charges if date is changed to earlier date.

I installed Sage Payment Gateway over a Magento website last year and got to come the same kind of problem for shipping in UK. I think you need to upgrade your Sage software to PRO if its free one as their free versions are not sufficient enough to get the work done.

Not knowing what you are using to setup your payment. Most
programs allow you to remove / delete this information.

When we issue post dated cheques then we have to maintain the dates on which it is likely to be presented in bank. Regular post dated cheques can be easily tracked e.g. cheques issued for some regular installments etc. But if the quantity of post dated cheques is large and the payment schedule is not regular then keeping track of all PDC becomes more important.

Tally can handle both PDC payments made by cheques and PDC cheques received by you. Tally has a facility to convert any voucher in post dated form. A post dated voucher is one which is going to be realized in future date. It would be reflected in books only on due date and not before this.

While entering the PDC cheque you have received just press 'Ctrl+T' in reciept voucher type and enter the voucher on that specific date.

In same way what ever post dated cheques issued by you can be entered in payment voucher by putting the voucher in post dated mode by pressing 'Ctrl+T'.

Now comes the real problem, How to see the status of these cheques? How to see which cheques is going to be cleared and which cheque is coming for payment? To do this a particular period can be specified in
Display -> Exception Reports-> Post Dated Vouchers
Here you would see all the post dated vouchers. Select voucher type as receipt or payment by pressing 'F4' to see the status on a specified period. You can change the period by 'Alt+F2'.

You can also see the total bills out standing amount with our without post dated vouchers.
If we see
Display-> Exception Reports->Overdue Receivables
then normal screen would be like this


But by pressing F12 and putting Include post dated transactions to Yes you can see the net pending amount also.
See the figure below how PDC amount can be seen. A new extra column would be added to show the net PD Amount.
The same thing can be achieved for Bills payable in
Display-Exception Report->Overdue Payables

You can request a payment deferral where they take your next payment and put it at the end of the loan thus allowing you the time to put the money up for the next payment and keeping you from being late. If all else failss i suggest that you look into refinancing with another bank or loan company at a lower apr rate.

Sage Line 50 Addpurch Utility
In Sage Line 50 V5, you could only produce remittances for the
supplier accounts you had set up in your Sage Line 50 program.
The information that appeared on your remittances was taken
from the supplier ledger.
In newer versions of Sage Line 50 you can produce remittances for suppliers
who do not have a corresponding supplier record. This allows
you to produce free-format cheques for one-off payments. To
enable you to produce free-format cheques, Sage Line 50 no
longer takes the information for remittances from the supplier
ledger. This means that you can produce remittances whether
there is a corresponding supplier record or not.
If you want to include additional information from your
supplier records on your remittances, for example bank sort
codes and account numbers, you should convert the layouts
you require using this utility.
Note: This utility is installed automatically into your
Sage Line 50 program directory when you install Sage
Line 50.
>> To use the Addpurch utility
1. Open a Command Prompt by clicking on to your Windows Start Button
selecting Run, then type the word COMMAND and click on to OK.
From the command prompt (for example, c:\windows\desktop>) type cd\ and
then press ENTER.
2. At the c:\> prompt type cd "Program Files\Sage Accounts\layouts"
and then press ENTER.
The prompt should now read c:\Program Files\Sage\Accounts\layouts
Note: If your Sage Line 50 program is installed in a different
directory replace the above instruction with your own directory
name. The directory path can be found within your program by
clicking on to Help and then About and choosing the System
Information Tab. Your layouts will be held on the same path
as your data directory.
3. Before you can convert your remittance layout you will
need to save this with a new filename. (maximum of 8 characters).
For example, to rename one of your existing layouts from
the c:\Program Files\Sage\Accounts\layouts prompt type:
copy remita4.sly newrema4.sly
and then press ENTER.

Most mature programs would do that as well as check to make sure the date format is consistent. Since I don't know what program you are using that's all the information I can give you.
