[ AUTOMATION WITHOUT RUTINE ]

How System Integrations Save Business Resources

When programs communicate with each other directly, the company works up to times faster and without human errors

[ 01 ]

Release of hundreds of working hours

Employees no longer spend time manually transferring orders from the site to accounting, copying phones into CRM or manually stamping TTNs.

[ 02 ]

Order Processing in Minutes

Client places an order — the system instantly deducts the product, issues an invoice, registers TTN and sends an SMS with the waybill number.

[ 03 ]

Current stock in all sales channels

The single source of truth: selling the product in the store instantly blocks its sale on the website, marketplaces Rozetka and Prom, excluding misclassification.

[ 04 ]

Full digital control for the manager

All financial and operational analytics are collected into a single report without the need to manually consolidate dozens of different tables.

[ FREQUENT QUESTIONS ]

Answers to common questions from customers

Key details regarding terms, independent website editing, and rights transfer.

Nothing will be lost. We develop integrations using message queues. If the receiving system temporarily does not respond, the request is stored in a secure buffer and automatically retries with increasing intervals once the connection is restored.

Yes. We have extensive practical experience configuring data exchange even with outdated and heavily customised 1C/BAS configurations. We create a dedicated external gateway or export script that does not disrupt your working configuration.

No. We configure asynchronous data exchange in the background mode (via webhooks and queues). The website visitor or customer does not feel any delays at all — the interface opens instantly.

Yes. We prepare a full interactive documentation Swagger / OpenAPI, where clearly described each method, data format, authorization headers and request and response examples.

We monitor the data exchange log daily, check for pending requests, update security tokens, and free of charge resolve any synchronization nuances for three months.
