Dyna,
There is a lot to think about when setting up GPS for the first time, too much to mention in this forum, but I offer the following suggestions:
1. Look at the setup section for each module in the On Line Manuals (Help -> Online manuals). The setup sections have a lot of info about getting started.
2. In the System Setup Manual read the Company Setup section paying particular attention to the Accounts chapter. When the account structure is setup, you pretty much carve things in stone, so you want to be sure you understand how it works and also allow for future expansion and ect. It is worth paying for a call to GP if you do not understand how it works.
3. Got to Routines -> Checklists -> Pick your module and select a frequency of setup. This will provide a sequential list of things you need to do.
4. Inventory setup seem a little convoluted to me, so study how pricing, account posting, item classes and etc. work before you start.
5. Frequently after setting up a new checkbook, I wind up making a few adjusting entries the first month we do a reconciliation. Don't worry about, go ahead start the checkbook the best you can. Then make sure the first reconcilation is done properly and reconciled to the ledger. It will work smooth after that.
6. When setting a ledger mid-year I frequently will go back to the end of the prior year, enter the year end balance sheet account amounts and do a year-end closing for the prior year. Then I will enter a journal entry to each ledger account, in each month that as passed (Jan, Feb & Mar in your case) for the account change. This way I can test my financial statement setup against the actuals and it also leaves the whole year in place so next year prior year comparisons are available.
7. Study how Item Classes, Vendor Classes, Customer Classes, Employee Classes work. They can save a lot of time if you setup the correct way for business.
Good luck, Gene
