Is “Sales and purchase invoice lists, aged debtors and creditors, attachments” on my plan?

Sales and purchase invoice lists, aged debtors and creditors, attachments sits at the Basic tier of the Accounts module. A feature opens when its tier is at or below the level your subscription holds for the module. Why it sits there: Reads of synced invoices; approval stays Basic (market table stakes). Your level is on Settings → Subscriptions.
