to setup
Create a service item called 'gift certificate', price 100.00
  no revenue/expense account

to sell
create an invoice, sell a GC, you'll need to specify 2470 as the account
  payment method is per the customer

to redeem
create a 0.00 invoice,
  line 1 is what the customer bought
  line 2 is 'gift certificate', -100.00, account 2470

to donate
create a 0.00 invoice,
  line 1 sell a GC, you'll need to specify 2470 as the account
  line 2 negative amount, specify the donation account

to writeoff an expired GC
create a 0.00 invoice,
  line 1 sell a GC, you'll need to specify 2470 as the account
  line 2 negative amount, specify the write off account

  since Sage Pro doesn't track serial numbers
  you'll need to track the serial # of issued / redeemed GCs offline
 

Thank you Roger.

For donation -- at the time of redemption the entry should be

debit - 2470 - gift certificate issued

credit - 4200 - sales

because at the time of donation - Journal entry should be

debit - expense account - donation or promotion

credit  - 2470 - gift certificate issued

thank you for your feedback - greatly appreciate it.

yes, at time of redemption (when sold or donated), an invoice recording what is bought (line 1) will credit sales and line 2 (- amount) will debit the GC liability
