A running record of what we ship. Each month's entries are the things merchants would actually notice. ## September 2026 ### Adyen payments A fourth payment provider, alongside Stripe, Razorpay and Dodo. Hosted Checkout on your own Adyen merchant account, with refunds, chargeback and manual-review notifications, and account discovery when you connect. Useful where acquiring is consolidated on one provider across several markets. ### Published software bill of materials Every dependency the product installs is now listed with its licence, alongside machine-readable SPDX and CycloneDX documents. The inventory is generated from lockfiles rather than maintained by hand, and is keyed by name and version so a package installed at two versions appears as both. A security team can point a scanner at it instead of asking. ### Enterprise deployment documentation Deployment models, tenancy and isolation, regional placement, capacity, identity, shared responsibility and data portability, gathered on one page. Migration is described as a sequence with checkpoints and a rollback window rather than a cutover date. ## August 2026 ### Public REST API, v1 A documented, versioned API over products, orders, customers and inventory, with scoped API keys you issue and revoke yourself. Webhook endpoints and their delivery history are managed through it too, which is where the merchant webhook work from April finished. Idempotent writes, cursor pagination, and a reference at docs.mercemur.com. ### Mercemur CLI Drive your store from a terminal or a script: log in once, point it at a store, and pipe the output into whatever you already use. Installs with a single command. ### MCP server for AI assistants Connect Claude or any MCP client to your store and edit the catalogue and the storefront by asking. Thirty-three tools covering products, collections, media, theme settings and page templates, with a preview before anything publishes. ### Email marketing built in Campaigns, automated flows, and segments that read your real order data, plus a preference centre your shoppers control. Growth includes 10,000 sends a month. ### Gift cards Sell gift cards, schedule delivery to a recipient, and let shoppers redeem them across multiple orders. Balances reconcile against the order ledger rather than a separate wallet. ### Shiprocket shipping for India Rates, labels, pickups, and tracking for Indian merchants without leaving the admin. Returns and NDR handling included. ## July 2026 ### New backend, live in production The platform now runs on a rewritten Go backend. Same URLs, same data, noticeably faster responses under load, and a much smaller memory footprint per store. ### Three checkout payment providers Connect Stripe, Razorpay, or Dodo Payments with your own account. Stripe and Razorpay charges land in your account; Dodo acts as merchant of record. Mercemur takes no per-transaction cut. ### Store locator Publish physical locations with opening hours, search by postcode or current location, and let shoppers filter by what a location actually offers. ### Storefront caching and image pipeline Product pages are served from cache at the edge, and uploaded images are converted into responsive variants automatically. Fewer bytes on the wire and faster first paint. ### Product reviews Collect reviews after fulfilment, moderate them from the admin, and show ratings on product and listing pages. Photo reviews and review requests included. ## June 2026 ### Multi-region storefronts Sell into several regions from one store, each with its own pricing, tax treatment and shipping options. Shoppers are routed to the right region by location, and can override it. ### Multi-currency checkout Shoppers see prices and pay in their own currency, with per-currency rounding rules you control instead of a raw conversion. ### Promotions engine Percentage and fixed discounts, buy-x-get-y, automatic and code-based promotions, with stacking rules and usage limits enforced server-side at checkout. ## April 2026 ### Platform and Solutions marketing pages Published dedicated pages for every capability in the Platform and Solutions sections of the site. Dead-links in the mega-menu are gone. ### Merchant webhook management (beta) Merchants can now configure their own webhook endpoints from the admin. HMAC signing and retries are handled for them. ### Subscription lifecycle polish Smoother trial-to-paid transitions, clearer dunning states on the customer profile, and fewer edge cases where Stripe and Mercemur's subscription engine could get out of sync. ## March 2026 ### Digital products, second pass Rebuilt license-key pools with pattern generation, per-entitlement download caps, and cross-tenant license validation via the public /licenses/validate endpoint. Subscriptions on digital products went from preview to production. ### ShipEngine integration Live shipping rates and label printing from the admin and checkout. Works across carriers; no per-carrier plugin setup. ### Custom domains with SSL Bring your own domain, apex or subdomain. Certificates are provisioned and renewed automatically. ## February 2026 ### Razorpay, Stripe, and DoDo payment integrations Three gateways live at the platform level. Merchants can run India via Razorpay and global via Stripe or DoDo on the same store, with per-region routing rules. ### Merchant admin revamp Full rebuild of the admin shell with a faster order table, a unified customer view, and mobile-friendly layouts that actually work on phones. ### Google Analytics GA4 integration Paste a GA4 measurement ID into the admin and storefront events flow automatically. No tag-manager gymnastics required. ## January 2026 ### Sales channels GA Sell the same catalog through your public website, a wholesale portal, and any further channel you define, each with its own pricing, stock, and visibility rules. ### Unified inventory across channels One source of truth for stock across every sales channel and region. When a unit sells anywhere, every channel knows about it in real time. Have a feature request? ## Have something you want to see shipped?
