Apps · Shopify, OpenCart, WooCommerce
Your store prints the waybill and receipt itself.
Twelve of our apps are in the Shopify App Store; the first came out in 2023. For OpenCart and WooCommerce we write the same to order: shipping, payment, fiscal receipts, marketplaces, exchange with 1C.
Shopify
Twelve apps, and every one passed review.
Nova Poshta and UkrPoshta, Rozetka, Allo, Epicentr and Hotline, Vchasno.Kasa, migration from Prom.ua, PDF invoices, exchange-rate repricing, cash on delivery in Colombia, visibility in ChatGPT. All install from the App Store and stay listed.
- Nova Poshta Shipping: 4.9 out of 5 · 12 reviews
- Four have a free plan
- Public and single-store apps
OpenCart
A module for a store that does not want to move.
The OpenCart store has been running for years, and moving costs more than extending it. We write shipping, payment and fiscal modules, marketplace feeds and exchange with 1C.
- For your process, not from a catalogue
- Exchange with 1C and ERP
- Price fixed after the specification
WooCommerce
A WordPress plugin when none exists off the shelf.
WooCommerce is the choice when the site already runs on WordPress and you need full control of the code. We write plugins for the carrier, the cash register and the marketplace, and connect the store to 1C or Dynamics 365.
- Shipping, payment, receipt
- Exchange with 1C and Dynamics 365
- Code in your repository
How we get an app into the catalogue
Specification before code.
Screens, data model, webhooks, pricing plans and the review checklist come before the first line of code. The price is fixed here too.
A demo every week.
A build on a development store. You test every step on your own orders.
We handle the review ourselves.
Submission, replies to the reviewers and resubmission are part of the fixed scope.
After launch.
API version updates, deprecations, support. Twelve apps have stayed in the catalogue since 2023.
What this page does not cover
The stores themselves: launching on Shopify, WooCommerce or OpenCart is described on the Online stores page. We do not write apps that bypass App Store rules: a rejected app costs more than a slow one.
