Profit margin scheme

VAT only on your margin, for second-hand goods.

If you sell used phones, pre-owned vehicles, trade-ins, or antiques, many tax authorities let you charge VAT only on your profit margin, not the full selling price. Toggle it in Settings > Modules & Features (VAT must be on first).

  • ✓VAT calculated on the margin, not the full sale price
  • ✓Loss sales produce zero VAT, no negative liability
  • ✓Serialized items use the specific unit's cost for the margin
  • ✓VAT Return report separates margin-scheme from normal sales
  • ✓Prints your custom declaration on every margin-scheme invoice

Margin-scheme eligibility is your accountant's call. EVRST does the arithmetic and the paperwork correctly; the rules vary by jurisdiction.

Refunds and negotiated prices, done properly.

Credit notes

A refund produces a credit note, never a rewritten invoice.

When you refund an invoice, EVRST produces a credit note with its own number, a reference to the original invoice, the lines coming back and the tax being reversed. An invoice records a sale that already went into your tax return, so it is not restated later.

  • ✓The original invoice keeps its figures and gains a block listing the credits raised against it
  • ✓That block prints on the A4 sheet and on the receipt-printer slip
  • ✓Refunding an overpayment issues a refund receipt instead, with no tax lines
  • ✓A Credit Notes screen filters by period, customer or document type, and exports to CSV
  • ✓An Owed back tab lists every paid invoice later edited down, so a surplus is never forgotten
Negotiated discount

Type the amount you agreed, not five line edits.

The bill comes to 5.900 and you settle on 5.500. Type 0.400 in the discount box under the totals, check the New total line, and apply. A discount code cannot do this, because the figure is different for every customer.

  • ✓Choose whether the amount reduces the printed total or the pre-tax value
  • ✓Set a staff maximum, a hard ceiling, and a maximum amount off the total
  • ✓Require a supervisor above the staff limit, and require a reason
  • ✓Works on invoices and at the till, and can be changed or removed later
  • ✓Reports > Sales > Register splits the total given away between codes and hand-keyed amounts

Common Questions

Frequently asked.

Can I give a customer a statement of account?
Yes. Open the customer, choose Statement of account, pick a date range, and print or save a PDF. The closing balance always matches the outstanding figure on the customer record, so you can hand it over when chasing payment.
Does it support the VAT profit-margin scheme?
Yes, for second-hand goods like used phones or vehicles. VAT is charged on your margin instead of the full price, a loss produces zero VAT, and the VAT Return report separates margin-scheme sales from normal ones. Margin-scheme invoices print your declaration instead of a VAT line.
Does a refund change the original invoice?
No. The original invoice keeps the figures it was issued with and simply shows which credit notes have been raised against it. The credit note is the document that records the reversal, which is what the tax rules ask for.
