Fiscal / Accountant demo workspace

A daily close
you can question.

Lia guides you through a fictional report. Choose a figure, open its calculation, and reach the order items behind the ticket. The accountant decides whether each proposed amount is right.

Public demo with invented data. This page does not approve, reconcile or issue invoices.

Guided walkthrough · Lia

Follow the proposed automation.

Choose a step. Listen or read; “View evidence” opens the related record.

Lia · guided example

At close, four fictional tickets total six thousand pesos: three thousand five hundred of food and two thousand five hundred of drinks. The matrix separates Mercado Pago, cash, card terminal and transfer; open any figure to see its transactions, then an amount in the ticket for the order items.

Accountant report · fictional sample

POS against every payment source.

Rows are sales categories; columns are payment methods. Each figure opens its contributing transactions and links to the ticket or source report. Source figures are gross, before fees.

Cash difference · MXN 30.00

POS MXN 2,500.00 − till MXN 2,470.00 = MXN 30.00. The demo threshold is less than MXN 100.00. A waiver is only a proposal for accountant review and keeps both source figures.

Awaiting review. No difference has been waived.

Municipal charge · proveout

4 guests in the proposal i × MXN 11.73 = MXN 46.92 proposed. POS records 5 guests: 4 on tickets over MXN 469.24 and 1 on the MXN 300.00 ticket. Guest-count difference 0. The accountant validates applicability and collection; the charge stays outside sales and the operational waiver.

Estimated included VAT: MXN 827.59, subject to classification review.

Audit trail

From difference to source.

Proposed VAT and municipal charge

Included VAT, assuming 16% on all four tickets: MXN 344.83 + MXN 344.83 + MXN 96.55 + MXN 41.38 = MXN 827.59. Guest-level municipal charge calculation follows; classification, applicability and collection require validation.

Environmental charge proveout

Independent Los Cabos bar example: 2026 daily UMA MXN 117.31; Article 137 Sexies refers to tickets over 4 daily UMAs (MXN 469.24). The proposed amount per included guest is 10% of the daily UMA: MXN 11.731, rounded to MXN 11.73. POS records 5 guests: 2 + 1 + 1 on tickets above the threshold, and 1 on the MXN 300.00 ticket that this proposal excludes. Control: 4 included + 1 excluded = 5 POS; guest-count difference 0. Proposal: 4 × MXN 11.73 = MXN 46.92. The accountant confirms applicability, other exclusions and collection; this demo records no municipal payment.

Period CFDI → reconciliation

With authorized e.firma, the service requests available issued and received XML and compares SAT's reported count with downloaded files. UUID, RFC, date, amount and status can suggest links. In this sample, PR-2081 · MXN 950.00 and TC-0929 · MXN 438.60 still lack verified documents; no real XML was downloaded.

Accountant decision

Four tickets potentially eligible for a global CFDI total MXN 6,000.00, subject to checking individual invoices and exceptions. The MXN 30.00 shortage may be proposed for waiver if policy allows; approval is required and the till figure stays intact. VAT MXN 827.59 and municipal charge MXN 46.92 await validation. This page issues no invoice.

Assumptions: Los Cabos Treasury · INEGI 2026 UMA · SAT CFDI. All tickets and movements here are invented.
