Second-hand · REBU
You sell second-hand items. VAT is not calculated on what you charge.
It's calculated based on your profit margin, and the invoice doesn't itemize it. Doing it manually for each order is time-consuming and increases the risk of errors. RKR REBU - VAT on margin for used goods It calculates the margin of each line, places the mention in each document, and keeps a logbook in which any alteration is detected by verifying the chain.
4 regimes
Used goods, works of art, antiques and collectibles, and exempt operation, by product or by category
4 legal mentions
Spain, Germany, France and the European framework: the store cites the standard of its country
1.7.8 → 9.x
a single version of the module for all your PrestaShop stores
/ From purchase price to margin, without spreadsheets
You record each purchase with its supplier, document number, date, units, and price. The module tracks the remaining units in each batch and, upon sale, calculates the margin for each line item: sale price minus the applied batch cost. If you prefer to adjust the margins for the month, you can also work with an overall margin per period, which is resolved in a single adjusting entry during the closing process.
Product with no purchase price
You decide what happens: zero margin, the entire price as margin, or return to standard VAT and draw the line.
Negative margin
Choose between 0% VAT without offsetting, recording the loss in the ledger, or applying standard VAT.
Mixed carts
If the customer mixes new and second-hand items, you choose how the VAT and mention are displayed.
Cancelled orders
The states you configure (default, voided, and refund cancellation) revert the lines in the book.
The module It does not modify any native PrestaShop totalsIt calculates and saves its own REBU figures in the module's tables. There is an advanced option to align the native rate with the margin, which is disabled by default.
/ A chained logbook: a retouch does not go unnoticed
Each transaction is recorded in the REBU ledger and sealed, linked to the previous one, using a unique SHA-256 fingerprint sequence. If someone alters or deletes a row, Verify string It tells you and points out where it breaks. When a period closes, its rows are sealed: the module rejects and records subsequent entries, and reopening it is an explicit action that is also recorded.
Closing of periods
You close the month from the book, or you schedule it with the module's cron job (tools/cron.php, (via command line).
Configurable retention
You set how many months to keep the book; the purge only removes sealed and already exported rows, and 0 means to keep it forever.
Audit
Sensitive actions are recorded with employee, IP address, and whether the token was valid.
/ Export for your manager
From the Import/Export menu, you extract the ledger in the AEAT format, with the columns and order of the Spanish VAT ledger (Article 137 of the VAT Law): chronological order, tax ID number and counterparty, document, description, margin as base, rate, and amount. It's sent as a CSV file with semicolons and UTF-8 encoding, ready to open with Excel in Spanish. The rest of the module's data (products, purchases, notifications, statistics) is exported in CSV, JSON, or XLSX, and imports are simulated before confirmation.
