Paying documents from existing credit (balance allocations)
Apply a contact's advance balance or prior payment to settle new invoices and bills.
A balance allocation applies a contact's existing credit balance (from a prior advance or overpayment) to a new invoice or bill. This reduces the amount the contact owes without requiring a new cash payment.
Before you start
- The contact must have an existing credit balance. Check their balance on the Contacts page.
- You are creating or reviewing an invoice (for customers) or a bill (for vendors).
- You need permission to create or edit documents. Ask your admin if you cannot access the document form.
- Confirm the currency matches: if applying a balance in a different currency, note the exchange rate.
Steps
For an Invoice (Customer Credit)
-
Go to Invoices → New Invoice or open an existing invoice to edit.
Open in Usystems -
Fill in the invoice details: contact, items, amounts, and tax.
-
Scroll to the Balance Allocations section (usually below the line items).
-
Click Add Allocation or + Allocate Balance.
-
In the allocation row:
- Contact is already filled (the invoice contact).
- Available Balance shows the customer's current credit.
- Choose how much to apply (either the full balance or a partial amount).
- Confirm the Currency and Amount to allocate.
-
Click Apply or Confirm to add the allocation.
-
Review the invoice total: it should now reflect the allocated balance as a deduction.
-
Click Save to complete the invoice.
For a Bill (Vendor Credit)
-
Go to Bills → New Bill or open an existing bill.
Open in Usystems -
Fill in the bill details: vendor, items, amounts, and tax.
-
Scroll to the Balance Allocations section.
-
Click Add Allocation or + Allocate Balance.
-
In the allocation row:
- Contact is pre-filled (the bill vendor).
- Available Balance shows your credit with the vendor.
- Choose the amount to apply.
- Confirm the Currency and Amount.
-
Click Apply or Confirm to add the allocation.
-
Review the bill total: it should be reduced by the allocated amount.
-
Click Save to complete the bill.
Accounting impact
When you allocate a balance to an invoice or bill:
- The contact's balance liability or asset account is debited (balance used).
- The receivable (for invoices) or payable (for bills) is credited (amount reduced).
This nets the two accounts, recording the settlement without requiring a separate payment entry.
Tips & common mistakes
- Allocate only available balances: check the contact's balance page to confirm they have credit before creating the allocation.
- Use partial allocations for flexibility: if the balance is larger than the document total, allocate only the needed amount and keep the excess for future use.
- Watch exchange rates: if the balance is in a different currency, the system will apply the current rate; confirm it is correct.
- Cannot undo easily: once saved, balance allocations are linked to the document. To reverse, you may need to delete and recreate the document or contact your admin.
