Frequently asked questions

Licensing & Pricing
What is a perpetual licence?
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.
What happens when I stop paying?
If you stop paying the monthly hosting fee, your access is paused, but your perpetual licence stays valid. We keep your data for 90 days, and our support team can send you a copy during that time. Restart hosting within 90 days and your platform picks up where you left off. After 90 days your data is securely deleted. If you're on the Seller Growth Programme and stop it, your platform continues running — you simply no longer receive the additional support services.
Are there any hidden costs?
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 rise each April by CPI or 3%, whichever is higher, and may also rise with 60 days’ notice if our costs go up. All prices are clearly stated: GBP prices include UK VAT, and USD and EUR prices are before tax.
Can we pay the licence in instalments?
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.
Can I upgrade my package later?
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
Can I add a channel after I have bought my licence?
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.
What sales channels are supported?
invtri has two types of sales channel. Core channels — A1TechDeals, eBay, TikTok Shop, OnBuy, Temu and Shopify — fill your package's included channels, and you can add more core channels as one-off extras. 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 marketplace you are approved on; Mirakl runs the marketplaces of 450+ businesses, including B&Q, Debenhams, Tesco and Currys). Amazon FBA & MCF is a separate add-on that works with your Amazon channel. Each marketplace, and your Shopify store, connects once per licence. Prices are on the Pricing page.
Which Mirakl marketplaces does invtri support?
Any Mirakl-powered marketplace where you hold an approved seller account. Mirakl runs the marketplaces of 450+ businesses worldwide, and invtri’s Mirakl directory includes B&Q, Debenhams, Screwfix, Currys, Tesco, Superdrug, Decathlon UK, ASOS, Harvey Nichols, Joules and Secret Sales. 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.
How does invtri connect to my Shopify store?
Through your own app (BYOK). In Shopify's Dev Dashboard, you create an app for your store, using the settings in our help guide. You enter the store address and the app's client ID and secret in invtri, then approve the connection on Shopify (an older custom app made in the Shopify admin can use its access token instead). invtri then creates products in your store from your supplier feeds once you approve them, keeps their price and stock up to date, and brings Shopify orders into your order dashboard. Shopify lets apps you create read customer names and addresses only on its Grow plan or higher, and invtri needs them for orders. One Shopify store per licence.
Can invtri import my existing marketplace listings?
Yes. The built-in Import Listings tool pulls your live listings from Amazon, eBay, OnBuy, TikTok Shop, A1TechDeals and Shopify 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.
Can invtri fulfil my eBay and other channel orders from Amazon FBA?
Yes. If a product is stocked in Amazon FBA, orders for it from eBay, OnBuy, Temu, TikTok Shop, A1TechDeals or Shopify can be fulfilled by Amazon Multi-Channel Fulfilment (MCF) from the order ticket: one click, you approve every order. 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.
How does Amazon FBA stock sync work across channels?
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.
What does Amazon MCF fulfilment cost?
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.
Is support included with the licence?
Yes — every licence comes with full platform access, managed hosting (a separate monthly fee), security updates, onboarding documentation and Basic support: help documentation plus email support for platform faults, with a target first response within 1 business day. 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.
What does BYOK (Bring Your Own Key) mean?
BYOK means you bring your own marketplace seller accounts and API credentials (Amazon SP-API, eBay, TikTok Shop, OnBuy, Temu, A1TechDeals, a Shop API key per Mirakl storefront, plus your own app for your Shopify store), 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.
Can I get a refund if a marketplace rejects my account or changes its API?
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.
Which countries can buy invtri online?
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.
Do I need technical knowledge to use the platform?
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 the Seller Growth Programme, we handle the initial setup, supplier configuration, and provide comprehensive training. If you're technically confident, a licence on its own gives you full self-service access.
What is included in the hosting fee?
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.
How often do stock and prices update?
Orders are pulled from every channel every 15 minutes. For each supplier, you choose when stock, prices and listings update: as often as every 5 minutes, or daily, weekly or monthly at a set time. You can also run an update straight away.
Which supplier feed formats work?
CSV or TXT, Excel (.xlsx or .xls), or a ZIP containing one of these, collected from FTP or SFTP. Catalogue, stock and price can be separate files, and you map the columns once in the app. XML, JSON, URL downloads, API feeds and email attachments aren’t supported. More on our Supplier feeds page.
How do dropship orders work?
invtri imports the order from the marketplace (every 15 minutes), records it and updates your stock on every channel. You then buy from your supplier as usual. When you add the tracking number in invtri, it sends it to the marketplace. More on our Dropship page.
How do I add tracking?
Add the tracking number to the order in invtri, and it’s sent to the marketplace, on every channel. For orders you fulfil through Amazon MCF, Amazon sends the tracking back automatically.
How are returns handled?
invtri tracks each return on the order: requested, received, then refunded or replacement sent. Return requests from Amazon, TikTok Shop and A1TechDeals come in automatically; on other channels you mark them. You can refund from invtri on eBay, OnBuy, A1TechDeals and Mirakl marketplaces. Arranging returns with your supplier is up to you.
Who arranges blind shipping?
You and your supplier. Blind shipping means the parcel and paperwork show your business, not your supplier’s, which Amazon’s drop shipping policy requires. invtri doesn’t ship parcels.
Setup & Support
How long does setup take?
With the Seller Growth Programme, 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. Customers with a licence on its own can self-configure at their own pace.
Do you offer a free trial?
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.
What support is available after setup?
Three options: Basic support — included free with every licence: help documentation plus email support for platform faults, with a target first response within 1 business day. 6-Month Seller Growth Programme — email support (up to 20 tickets/month), Teams meetings (up to 2 hours/month), and 1 business day response time. 12-Month Seller Growth Programme — everything in 6-month with extended coverage. Ad-hoc support is always available on request.
Data & Security
Is my data secure?
Yes. invtri is hosted in the UK and every connection to it is encrypted (HTTPS). The marketplace API keys you enter are encrypted when stored, and passwords are stored hashed, never in plain text. We take daily backups. You can turn on two-step sign-in with a code sent by email, and the account owner decides which sections each team member can see. Your data is yours: export it to CSV or Excel at any time. More on our Security page.
Can I export my data?
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.
What happens to my data if I stop using invtri?
We keep your data for 90 days after your hosting stops, and our support team can send you a copy during that time. After 90 days it is securely deleted. Your perpetual licence stays valid — if you restart hosting later, you can re-import your data and continue.
Is there two-step sign-in?
Yes. Turn it on, and we email you a code each time you sign in.
Can my team use invtri?
Yes. The account owner adds team members, up to the plan’s user limit, and chooses which sections each person can see. Each person has one active login at a time.
