Techzola Circular
Re-commerce ready.
Native buy-back module handling complex "Vinstmarginalbeskattning" (Margin VAT) for used goods—a huge differentiator for sustainable brands entering the circular economy.
Why Most Retailers Avoid Buy-Back
Buying used goods from consumers and reselling them triggers "Vinstmarginalbeskattning" (Margin VAT)—a special tax regime where VAT is only paid on the profit margin, not the full sale price. Most POS systems can't handle this complexity.
The result? Retailers either avoid re-commerce entirely, use manual Excel workarounds, or risk tax compliance errors. Techzola Circular solves this with native support for margin-based taxation.
// Standard VAT (new product) Sale: 1000 SEK VAT (25%): 200 SEK Net: 800 SEK // Margin VAT (pre-owned) Purchase from customer: 400 SEK Sale: 1000 SEK Margin: 600 SEK VAT on margin only: 120 SEK Net: 480 SEK // Techzola handles this automatically { "vat_scheme": "margin", "purchase_price": 400, "sale_price": 1000, "taxable_margin": 600, "vat_amount": 120 }
Complete Buy-Back Workflow
From customer walk-in to resale, Techzola Circular manages the entire pre-owned lifecycle.
Intake & Valuation
Customer brings item. Staff assess condition using guided checklist. System suggests fair buy-back price based on market data.
Purchase & Payment
Record seller details for tax compliance. Pay via cash, Swish, or store credit. Purchase price locked for margin calculation.
Refurbish & List
Track refurbishment if needed. List on POS and e-commerce with "Pre-Owned" badge. Set sale price; margin auto-calculates.
Sell & Report
Sell at POS or online. Margin VAT calculated at checkout. Financial reports separate margin-taxed sales for accounting.
