Frequently asked questions
Everything you need to know about invtri, our perpetual licence model, and how the platform works. Can't find what you're looking for? Get in touch.
Licensing & Pricing
A perpetual licence means you pay a one-off fee and own the right to use the software indefinitely. Unlike subscription software where you pay monthly and lose access when you stop, your invtri licence never expires. The licence fee is a one-time payment — there are no recurring licence charges, no per-order fees, and no revenue share.
If you stop paying the monthly hosting fee, your platform hosting is paused — but your perpetual licence remains valid. You don't lose your licence or your data. If you resume hosting, your platform picks up where you left off. If you're on a managed service plan and stop that, your platform continues running — you simply no longer receive the additional support services.
No. You pay the one-off licence fee, a fixed monthly hosting fee, and any optional one-off channel add-ons you choose — every amount is shown before you pay. No per-order charges, no revenue share, no annual price increases on the licence, no onboarding surprises. Hosting fees may be adjusted annually in line with CPI only. All prices are clearly stated: GBP prices include UK VAT, and USD and EUR prices are before tax.
Yes. UK limited companies paying in GBP can spread the licence and any channel add-ons over 3 or 12 monthly instalments with iwocaPay at checkout. Interest applies and is set by iwocaPay — you see the exact monthly amount before you commit. Hosting is billed separately by card.
Yes. If your business grows and you need more SKU capacity, additional channels, or more supplier profiles, you can upgrade to a higher package. The upgrade fee is the difference between your current licence and the new package. To arrange it, open a support ticket inside your invtri portal.
Platform & Features
Yes. Open a support ticket inside your invtri portal and tell us which channel you want. We will send you a secure payment link and switch it on as soon as it is paid. Channel add-ons are one-off and stay with your licence.
invtri supports seven sales channels. Five core channels — A1TechDeals, eBay, TikTok Shop, OnBuy and Temu — fill your package's included channels, and you can add more core channels as one-off extras. Two premium channels can be added to any package as one-off add-ons: Amazon (one region per licence — Amazon US, or Amazon Europe including the UK) and Mirakl Marketplaces (one connection covers every Mirakl-powered retailer marketplace you are approved on — B&Q, Debenhams and 300+ more). Amazon FBA & MCF is a separate add-on that works with your Amazon channel. Each marketplace connects once per licence. Prices are on the Pricing page.
Any Mirakl-powered retailer marketplace where you hold an approved seller account — including B&Q, Debenhams and 300+ more worldwide. Connect each storefront with its own API key; invtri lists your products by EAN against the retailer’s catalogue, imports your existing offers, and keeps orders, stock and prices in sync per storefront. Storefronts are unlimited and all sit under the single Mirakl Marketplaces channel slot. Seller approval, any marketplace subscription and commission rates are set by each retailer directly — invtri adds no per-order fees. Mirakl Marketplaces is a premium channel you can add to any package.
Yes. The built-in Import Listings tool pulls your live listings from Amazon, eBay, OnBuy, TikTok Shop and A1TechDeals straight into invtri (Temu via CSV upload; Mirakl storefronts have their own one-click offer import). Imported listings are staged for your review and matched to your supplier feeds by SKU and EAN — nothing changes on your live marketplaces until you approve. Prefer us to do it? Free listing migration is included with every licence — request it through the contact form.
Yes. If a product is stocked in Amazon FBA, orders for it from eBay, OnBuy, Temu, TikTok Shop, A1TechDeals or your webstore can be fulfilled by Amazon Multi-Channel Fulfilment (MCF) with one click from the order ticket. Amazon picks, packs and ships the order, tracking is pushed back to the marketplace automatically, and the order is marked shipped. On eBay orders, Amazon Logistics is blocked by default so deliveries stay within eBay’s carrier rules.
invtri mirrors your FBA inventory automatically — fulfillable stock per SKU, refreshed hourly and on demand. Products you list from the FBA hub to other channels take their stock from FBA and their price from your per-channel rule (same as Amazon, or add/deduct by £ or %). When FBA stock changes, the listed channels update on the next sync.
Amazon charges its standard MCF fulfilment fee per order, billed by Amazon through Seller Central — invtri adds no per-order fees on top. You need an active Amazon Professional selling account with stock in FBA. FBA and MCF come with the Amazon FBA & MCF add-on, which works with your Amazon channel — both are one-off add-ons unless your package includes them.
Yes — every licence includes full platform access, hosting, security updates, onboarding documentation and Basic support: help documentation plus email support for platform faults, with a target first response within 2 business days. The Seller Growth Programme (6-month or 12-month) adds dedicated hands-on setup, training, marketplace guidance, and monthly support tickets for sellers who want a dedicated team as they launch or scale. The Seller Growth Programme is optional — the platform is fully functional without it.
BYOK means you bring your own marketplace seller accounts and API credentials (Amazon SP-API, eBay, TikTok Shop, OnBuy, Temu, A1TechDeals, plus a Shop API key per Mirakl storefront), supplier trade accounts with FTP/SFTP feeds, and optional product data subscriptions (e.g. Icecat, UPCitemdb). You connect these to invtri and we provide the platform that automates listings, pricing, and stock across all channels. Revenue flows directly to your marketplace accounts. No revenue share, no vendor lock-in, and full control over your accounts and data. If you stop using invtri, your marketplace accounts and supplier relationships continue unaffected. You obtain, own and pay for your marketplace seller accounts and API credentials; we never hold or manage marketplace accounts for you.
No. invtri works through your own seller accounts and API keys (BYOK). Whether a marketplace approves, keeps or limits your account — and how it runs its API — is decided by that marketplace, not by us. Licence and add-on fees are non-refundable once activated, so please check you can get a seller account and API access before you buy. If a marketplace permanently shuts down its API for all sellers, we may, at our discretion, move your allocation to another channel of equal or lower price.
Businesses in the UK (companies and sole traders) pay in GBP, with UK VAT included. VAT-registered businesses in the EU pay in EUR before tax — no VAT is added under the reverse charge, and a valid EU VAT number is required. Businesses in the US pay in USD before tax. Your currency is set by the country your business is based in, and we check it against your billing address and card. Businesses anywhere else: please contact us for a quote.
No. invtri is designed for e-commerce operators, not developers. The platform runs in your web browser — there's nothing to install. If you choose a managed service package, we handle the initial setup, supplier configuration, and provide comprehensive training. If you're technically confident, the Platform Only option gives you full self-service access.
The monthly hosting fee covers everything needed to run your platform: server infrastructure, security monitoring, SSL certificates, database management, backups, platform updates, and security patches. We manage all of this on your behalf. You simply access the platform via your web browser.
Setup & Support
With a managed service package, most platforms are fully configured and live within 2–4 weeks, depending on the number of suppliers and channels. This includes supplier feed integration, channel connection, pricing rule configuration, and comprehensive training. Platform Only customers can self-configure at their own pace.
Yes. We offer a 7-day trial (limited use) for eligible businesses so you can see the platform in action with your own products and channels before committing — no card required. Trials run in a test environment as standard; full trial conditions are in our Terms. Book a demo and we'll get you set up.
Three options: Basic support — included free with every licence: help documentation plus email support for platform faults, with a target first response within 2 business days. 6-Month Managed Service — email support (up to 20 tickets/month), Teams meetings (up to 2 hours/month), and 1 business day response time. 12-Month Managed Service — everything in 6-month with extended coverage. Ad-hoc support is always available on request.
Data & Security
Yes. Your platform is hosted on secure, enterprise-grade infrastructure in UK data centres. All data is encrypted in transit and at rest using industry-standard encryption. Access is role-based, and we apply security patches and updates continuously. Your data is logically isolated from other customers and never shared with third parties.
Yes, at any time. You have full ownership of your data. You can export your inventory, calculated prices and P&L to CSV or Excel whenever you need to. Your data is never held hostage — it’s yours.
Your data remains available for export for 30 days after your hosting lapses, in line with our licence terms. After that, it is securely deleted from our systems. Your perpetual licence remains valid — if you resume hosting in the future, you can reimport your data and continue where you left off.
