Bulk Printing A/R Invoices

Washington State law does not strictly mandate a specific "individual invoice for every payment" in a universal sense for all businesses. However, it does require itemized documentation for every transaction to ensure accurate tax reporting and audit compliance.
If you are managing an AR account in a system like Stayntouch (SNT), the requirement is less about the physical paper and more about the data trail.
1. Sales Tax Compliance (RCW 82.08.050)
The Washington Department of Revenue (DOR) requires that retail sales tax be separately stated on every "sales slip, contract, invoice, or other sales document."



• The Rule: If you combine multiple charges into one lump sum payment on an AR account without showing the tax breakdown for each individual sale, the DOR will assume sales tax was not paid.



• Practical Application: Your system must be able to produce an itemized record (like an individual invoice) for each charge to prove the correct tax was collected for that specific jurisdiction.
2. Recordkeeping Standards
Under WAC 458-20-193 and general state auditing guidelines, businesses must maintain "sequentially numbered" records of all charges and credits.
• Subsidiary Ledgers: You are required to maintain a detailed subsidiary ledger that tracks each "outstanding amount due" individually.



• Payment Linking: When a payment is received for an AR account, it must be recorded in a way that discloses the name of the payee and the invoice number it is being applied to.

From Cobblestone Lynden: Currently what I have been doing is sending individual emails 1 by 1,  and then following up with a statement for the accounting team I am emailing the invoices to.

However, due to the time frame it takes to send each individual reservation, and wait for it to open, and then send, it is very time consuming, and very easy to miss sending the invoices, or get lost about which invoice I just sent. 

If there was an easier way to send all invoices with one click, or something easier to track which invoices have been sent, that would be great.
