Invoices are the billing records for amounts owed by customers. Lynka keeps invoice creation, accounting posting, stock fulfillment and payment settlement separate because each action changes a different part of the business record. Open Agreements > Invoices to search, create and manage invoices.

​
Create and review

Build the invoice with the correct customer, currency, lines, quantities, prices, discounts, tax and due date. Review the total before posting. Creating an invoice does not necessarily create accounting activity. Posting is a separate action that depends on permissions and workspace capability.

​
Post to Accounting

When posting is enabled and the document is ready, the posting workflow can create the accounting treatment for receivables, revenue and tax. Users may need invoice.post or related invoice management permissions.

​
Record settlement

Customer payment should be applied through the controlled payment workflow. Cleared payments reduce the receivable; pending activity should not silently make the invoice look settled. Partial payments leave a remaining balance.

​
Fulfill stocked items

If the invoice contains stocked products, fulfillment records the stock actually delivered. Recognized inventory cost for stocked items depends on posted fulfillment rather than assuming every billed unit has already left stock.

​
Corrections

Use supported void, refund or credit workflows for corrections. Do not rewrite posted financial history merely to force a desired result.
