/// Honest exclude
What this isn't.
We'd rather tell you on the call than at week six.
A Shopify clone — if Shopify or WooCommerce fits, we'll say so and recommend you stay there.
A guarantee against fraud — we ship 3D Secure + fraud scoring, but no platform is bulletproof.
A solution for cash-only handovers — chargebacks exist and we'll design around them.
/// FAQ
Asked on most calls.
Why not Shopify?+
If Shopify fits — use Shopify. We build custom when you need things Shopify doesn't do well: marketplaces with split payouts, deep custom logic, low transaction fees at scale, or B2B catalogues.
What about VAT, MTD, sales tax?+
Handled. We wire to UK MTD-compliant accounting and US sales-tax services if you sell across borders.
Can you handle physical product fulfilment?+
We integrate with the warehouses you already use (Royal Mail, DPD, ShipBob, your own ops). We don't run the warehouse.
