Own your platform. Stop renting it.
Most multichannel software is rented by the month. Published UK prices run from free or under £100 a month for small sellers to £4,600 or more a month for larger ones (ex VAT), and the fee usually rises with your orders or turnover. Some platforms also take a percentage of your sales. The longer you use them, the more you pay, and if you leave, you lose access.
invtri is different. Pay a one-off licence fee. Own it forever. Hosting is a fixed monthly fee. No per-order charges, no revenue share, and your licence fee never increases.
Two very different business models
PERPETUAL LICENCEOne-off licence fee + monthly hosting
Hosting only — no licence payment. Ever.
Typical SaaS Platform
SUBSCRIPTIONFrom under £1,000 to over £50,000 a year (ex VAT), every year
Repeats every year. Price increases common. Leave and you lose everything.
How invtri compares to subscription platforms
| Feature | Typical SaaS Platform | invtri |
|---|---|---|
| Pricing model | Monthly or annual subscription — pay every month, forever | Perpetual licence — pay once, own it forever. Hosting billed monthly. |
| Revenue share | Some platforms take a % of your sales or charge per-order fees | Zero. No revenue share, no per-order fees, ever. |
| Your marketplace accounts | Platform may intermediate or co-manage your accounts | BYOK — you connect your own accounts and API keys. Revenue goes directly to you. |
| Data ownership | Your data lives on their servers under their terms | Your data is your property. Export inventory, calculated prices and P&L to CSV or Excel at any time. |
| Vendor lock-in | Leave and you lose access. Start again with a new provider. | Leave and your marketplace accounts, supplier relationships, and products remain yours. |
| Price increases | Contracts can allow a price rise at every renewal. | Licence fee is one-off and fixed. Hosting rises each April by CPI or 3%, whichever is higher, or with 60 days’ notice if our costs rise. |
| Support included | Usually bundled — you pay for it whether you use it or not | Platform support always included. Expert hands-on support available separately — pay only if you want it. |
| Channels | Channels are often included, but the fee rises with your orders or turnover. | All supported channels, paid once: core channels, including Shopify, come with your package; Amazon and Mirakl Marketplaces are one-off add-ons. Mirakl alone covers every Mirakl-powered marketplace (Mirakl runs the marketplaces of 450+ businesses, including B&Q, Debenhams, Tesco and Currys) under one connection. You connect your own accounts (BYOK). |
| Instalment payments | N/A — you pay every month anyway | Spread the licence fee over 3 or 12 months with iwocaPay. |
| Onboarding | Paid onboarding or self-service with trial | Onboarding manual included. Expert setup available via support packages. |
| Security updates | Included in subscription | Included in hosting fee — no extra charge. |
| Custom development | Can be a paid extra, sometimes from third-party developers. | Available as ad-hoc work at agreed rates. |
| Sell your business | Buyer inherits your subscription costs. No asset to transfer. | Licence is an asset. No ongoing licence payments for the buyer. |
| Platform acquired by competitor | Pricing and terms can change under the new owner. | Your perpetual licence is unaffected. Your platform is independent. |
The longer you use invtri, the more you save
With a subscription, your costs stay flat or increase every year. With invtri, your licence is paid and your only ongoing cost is hosting.
| Business size | invtri Year 1 | invtri Year 2+ | SaaS subscription |
|---|---|---|---|
| Solo seller (500 SKUs) | Licence + hosting | Hosting only | Still paying full subscription |
| Growing business (5,000 SKUs) | Licence + hosting | Hosting only — licence already paid | Subscription × 2 years. Price may have increased. |
| Multichannel (20,000 SKUs) | Licence + hosting | Hosting only — licence already paid | Subscription × 3 years. Per-order fees add up. |
| High volume (100,000+ SKUs) | Licence + hosting | Hosting only — licence already paid | Subscription × 5 years. Revenue share compounds. |
All invtri GBP prices include UK VAT; USD and EUR prices are before tax. Subscription prices are from multichannel platforms’ own published UK pricing, checked October 2026, and exclude VAT. Some platforms only give prices on request.
What happens when your business changes?
The real cost of a platform shows up when your circumstances change.
| Scenario | Typical SaaS Platform | invtri |
|---|---|---|
| You grow from 5,000 to 50,000 SKUs | Your subscription tier increases. Monthly cost jumps. | You upgrade your licence (pay the difference once). Hosting adjusts to the new tier. |
| You have a quiet month with low sales | Still paying the full subscription fee regardless of usage. | Hosting fee only. Your licence is already paid. |
| You want to pause for 3 months | Cancel your subscription and you lose access until you subscribe again. | Pause hosting. Resume when ready. Your licence is still valid. |
| You sell your business | The buyer takes on the ongoing subscription. | Licence is an asset. No ongoing licence payments for the buyer. |
| Your platform provider gets acquired | Pricing and terms can change under the new owner. | Your perpetual licence is unaffected. Your platform is independent. |
| You want to switch platforms | You lose access when you leave. What you can export depends on their tools and contract. | Your marketplace accounts and supplier relationships are yours. Export inventory, prices and P&L to CSV or Excel. |
