Best POS for a boutique in London
Last reviewed 2026-08-05 · by the RetailPOS team
A single womenswear shop in Notting Hill and a two-site independent label need the same core: inventory that understands size and colour. Here is what to insist on in London, and where RetailPOS fits.
What a London boutique POS must do
1. Variant grids. One product, many size × colour SKUs, entered and counted as a grid rather than dozens of separate items.
2. Sell-through by dimension. See which sizes and colours sell and which sit, so you buy the next season on real data.
3. Wishlist & back-in-stock. Capture demand for out-of-stock sizes and notify the customer when they return.
4. VAT & clean receipts. Standard 20% VAT applied per line with tidy receipts and returns/exchanges by variant.
5. Multi-store on the base plan. Central catalogue, per-shop stock and transfers between sites without paying up a tier.

Where RetailPOS fits — and where it doesn’t
Pick RetailPOS if you want variant-aware inventory, sell-through and multi-store without climbing a pricing tier, with your own processor.

Frequently asked
- Does it handle size and colour as a grid?
- Yes — one product carries its size × colour variants as a grid, each with its own stock and barcode, rather than a long list of separate items.
- Can I see which sizes and colours sell best?
- Yes — sell-through reporting breaks down by dimension so you can buy the next season on what actually moves.
- Does it do multi-store without a higher tier?
- Yes — multi-store, central catalogue and inter-store transfers are on every plan; see how to choose a multi-store POS.
