Importing invoices from Wave with partial payment

Importing invoices from Wave with partial payment

Hello,

I'm converting from Wave Accounting to Zoho Books.  For the most part is has been fairly painless, but I do have a few hiccups.  I have invoices from prior to my conversion date (7/1) which have a partial payment applied.  When I import the invoices, though, there is no payment information included in the invoice detail.  Payments are a separate part.  The issue is that if I import the invoice, it'll show the entire balance due in Zoho.  If I then also import the payment info, it'll increment up my bank account by however much the partial payment was.  

It appears that the "beginning balance" for my bank account, really isn't a final balance, but more of a "add this at this time".  Wondering if there is a well known way to handle this.

I guess I can apply the payment, then compare trial balance from both programs for 6/30, and in Beginning balances, enter in something that makes the trial balance appear correct.  Unfortunately, though I would also have to do that for Accounts Receivable and Sales, as Wave includes the balance due as AR, and the partial payment as Sales.  In Zoho, my AR will include the entire invoice, and the partial payment as Sales - in effect counting them twice....

Any ideas?
Thanks!
