13x revenueFrom a single Odense store to seven-figure revenue — over a five-year partnership.

02The growth engine

We ran our framework end to end, with Meta and Google as the acquisition layer and Klaviyo to pick up the low-hanging fruit and build loyalty. The organic content strength they already had was repurposed as paid distribution — and budgets were steered on profit via Profitmetrics rather than the platforms' own numbers. The business stayed profitable the whole way through.

03Under the hood

Alongside it we built their platform from scratch — it runs today at portal.matraws.dk. Customers hand in collections straight from the site: fill in the form, pay the shipping, and the label lands automatically in your inbox — or drop the collection off in one of the stores. Every collection gets its own journey: intake with shelf location, line-by-line valuation with market prices as reference, and a digital offer the customer accepts in one click — with a free choice between cash payout and store credit at a higher rate. Messages go out automatically at every step, by email and SMS, with reminders for anyone who hasn't replied. Several hundred collections have been handled through the system.

04Bookkeeping without hands

Used goods are taxed on the margin, not the sale price — and with thousands of used single cards, that is impossible to bookkeep by hand. The platform generates one VAT document per order, split into margin-scheme and standard VAT, ready for the VAT return with bulk exports for the accountant. The purchase record attaches automatically when an offer is accepted; if anything is edited after posting, a credit note and a new record are created on their own. Cost prices are searchable across every collection ever bought, so the margin can always be documented.

05The automation web

Around the platform grew a web of tools: a notification and dispatch system on an SMS gateway and Resend, a bookkeeping flow running directly over REST to e-conomic and coupled with Storebuddy — purchase records, sales invoices, VAT and cost prices in one place. A custom returns flow built for the EU right-of-withdrawal rules effective 18 June, with no fixed app costs. Order consolidation for customers, a demand tool for purchasing and the hot-buy list, ongoing price checks against the market, and in-house replacements for the apps they used to pay a fixed fee for. The gain isn’t a number of hours on a spreadsheet — it’s capacity: new products go online in bulk because weights, VAT and prices correct themselves, and every step from intake to posted record runs without hands.

06The customer layer

The newest layer faces the customers: a binder system where collectors build their collection set by set and stamp the cards they own — every missing card mapped against live inventory, so the wishlist goes into the cart in one click. The binders feed demand data back to purchasing and trigger automatic alerts when a wanted card is back in stock. On top of that: a free price-check tool with live market prices, self-service for cancellations, returns and order merging — and an SMS queue system for physical events where customers follow their place in line live.
