Base.com (formerly BaseLinker) charges per order — cheap on day one, growing with every sale you make. Salync gives UK sellers flat GBP pricing, real-time sync, purchase orders and UK-first marketplace coverage. Your bill shouldn't rise because your business works.
No credit card required · Flat GBP pricing · No per-order fees
Base.com is a capable platform with a huge integration list — and a pricing model that quietly taxes growth. After the free tier, you pay a base fee plus a fee for every order processed. Sell more, pay more, forever. For a growing UK seller, that maths gets worse every month.
Growth tax
Per-order fees mean doubling your sales roughly doubles the volume component of your bill. Salync is flat: £99/month covers 2,000 SKUs however many orders you take.
EU-first heritage
BaseLinker grew up on Allegro and the Polish market. UK marketplace priorities — B&Q, Tesco, OnBuy, Royal Mail workflows — are not its centre of gravity.
Support distance
Reviewers mention slow responses during critical incidents. Salync support runs on UK hours and understands eBay UK and Amazon UK specifics.
The same core job — with pricing that stays put as you grow.

The most common reason is the pricing model: after the free tier, Base.com charges a base fee plus a fee per order. At low volume it is genuinely cheap, but the bill grows with every sale — sellers doing hundreds or thousands of orders a month watch their software cost climb alongside their success. Reviewers also mention support responsiveness during critical incidents, and UK sellers note the platform's Polish/EU marketplace heritage shows in its coverage priorities.
It depends on your volume — and that is the point. At 50 orders a month Base.com is very cheap. At 1,000+ orders a month, per-order fees add up while Salync stays flat at £99/month (Growth, up to 2,000 SKUs) or £299/month (Pro, up to 10,000 SKUs). If your order volume is growing, flat pricing gets better every month.
Base.com is a broad platform with 1,700+ integrations including many EU marketplaces (Allegro, Kaufland, Empik) plus modules like a built-in repricer and WMS. If you sell heavily into Poland or the wider EU marketplace network, that coverage is a real advantage. Salync focuses on UK sellers: eBay UK, Amazon UK, Shopify and UK retail marketplaces like B&Q, Tesco and OnBuy via Mirakl, with UK-hours support.
