System integration

What it is

Most growing companies do not run on one system; they run on five or ten. Orders arrive in a shop or by message, stock lives in a spreadsheet or a WMS, invoices come out of accounting software, and payments land in a bank or a mobile wallet. System integration builds the connections between those tools — through APIs, webhooks, file exchanges or an automation layer such as n8n — so that each event is captured once and passed on to every system that needs it.

Integration is not the same as replacement. The accountant keeps the accounting package, the sales team keeps the shop, and the warehouse keeps its scanner app; what changes is that they now share data. A good integration also decides which system is the master for each kind of record — items, customers, prices — so that two tools never disagree about the same fact.

Why it matters for a growing business

The cost of disconnected systems is invisible at first and then very visible: staff copy orders from one screen to another, stock is sold twice because the shop and the warehouse hold different counts, and finance chases documents that already exist somewhere else. Every manual hand-off is a delay and a chance for a typo.

Once systems are integrated, an order placed online can reserve stock, raise a delivery, post the invoice and message the customer without a person touching four tools. Managers see one position instead of reconciling several, and new tools can be added later without another round of double entry.

How AutoProbaho uses it

AutoProbaho maps which systems a client runs, decides where each record should live, and builds the connections with APIs, webhooks and n8n — for example linking a custom ERP to accounting software, bKash or SSLCommerz payments, Daraz or Shopify orders and WhatsApp notifications. Integrations are documented, monitored and owned by the client, so they keep working when a tool or a team changes.
