1. July is the anomaly, and it is the undelivered-traffic point. Carrier charges run at 0.504 to 0.667 of the messaging line in every ordinary month, averaging 0.574. In July 2026, after sending had moved off the platform, the ratio was 1.044: carrier $1,376.21 against messaging $1,318.12. Outbound volume collapsed and carrier charges did not follow it down. The Usage Activity export itemised by traffic type, July first, is what tests this.
2. The 2.9% convenience fee cost $3,944.19 in 2026 alone ($4,897.34 lifetime). It first appears on the November 2025 statement; April to October 2025 show neither it nor sales tax. It reconciles to the cent as 2.9% of the usage subtotal. The executed Service Order does not contain it, and it does say the customer "will set up and maintain ACH billing".
3. Sales tax added $7,491.57 in 2026 ($8,550.00 lifetime), also first appearing in November 2025 and absent from December.
Sending moved to Klaviyo during June and July 2026. For scale, this is what the two platforms cost in the same months. Klaviyo billed no SMS line before July 2026; the June amount is a mid-cycle proration.
| Month | Postscript | Klaviyo, SMS line | Klaviyo, platform line | Klaviyo total |

Source. Postscript billing portal, captured by screenshot 2026-08-31 while logged in. The portal at app.postscript.io/billing/overview is session-gated and returns 404 unauthenticated, and the Postscript API key returns 401, so the billing history cannot be pulled programmatically.
Reconciliation. Every row here matches the billing-record memo already in the file. The 2.9% fee column reconciles to 2.9% of each usage subtotal within one cent in all eight months.
Not included. Invoices are addressed to the company's accounts-payable mailbox, not the sender's. Any statement not visible in the captured portal view is not represented here.
