Integrating with couriers and Microinvest: what actually saves hours
How automatic waybill generation and Microinvest Склад Pro stock sync work in practice — and where the investment actually pays off.
A small business selling online usually goes through the same phase: orders come in, someone manually types the address into the courier's system, someone else checks whether the product is actually in stock, a third person spends the end of the day reconciling two systems by hand. It works while orders are in the low tens per day. Then it stops working.
What a courier integration does
Bulgaria's main couriers, Econt and Speedy, both expose an API — Econt via XML or SOAP/JSON, Speedy via REST with JSON. In practice that means:
- The waybill generates automatically on order confirmation, using the address and data from checkout — no manual entry.
- The customer sees a real shipping price at checkout, not an estimate, because the system asks the courier directly.
- Tracking updates itself — shipment status shows in the customer's account without anyone copying it over by hand.
- Pickup offices and lockers load live from the courier's API, so the list is always current.
For WooCommerce, Shopiko, Magento and most common platforms there are ready-made modules for this that need no custom code — worth the money if your platform is standard.
Syncing stock with Microinvest
If you run your inventory in Microinvest Склад Pro, the usual problem is a mismatch: the store shows stock that's actually sold out, or the reverse. The bridge between the two systems is Microinvest Utility Center, an application that periodically syncs:
- stock levels from the warehouse to the site,
- new products and customers from the site back into Склад Pro,
- order statuses in both directions.
Ready-made platforms (Shopiko, CloudCart, Seliton) have built-in modules for this. For a custom site or non-standard logic — reserved stock on order, separate warehouses by location — the sync is built to fit on top of the same API.
When it's actually worth it
Integration isn't a universal "yes". The point where it pays off:
- Above roughly 15–20 orders a day — below that, manual entry is tolerable.
- More than one sales channel (site + physical store, or site + marketplace) — that's when a stock mismatch becomes a real risk of selling something you don't have.
- Recurring address or stock errors that have already cost you money or unhappy customers.
Below those thresholds, a ready-made plugin at €25–50 a month is the smarter call over a custom integration.
The real effect
| Step | Manual | With integration |
|---|---|---|
| Creating a waybill | 2–4 min/order | Automatic |
| Checking stock | Manual warehouse lookup | Live at checkout |
| Updating the customer on status | Manual message | Automatic |
| Address/stock errors | Regular | Rare |
At 20 orders a day, the minutes saved on waybills and lookups add up to an hour or two daily — that's a person-hour spent on other work instead.
That's the exact logic behind Studio Botema's internal ERP — orders, stock and suppliers in one system instead of manual email coordination. At LuminaVera, which sells into several markets at once, accurate stock sync between warehouses and the storefront is what keeps them from selling a product they don't have.
Integrations are usually also the biggest factor in a project's price — see the real pricing breakdown to gauge the scale. If you recognize the threshold above, describe your process — we'll tell you honestly whether a ready-made module is enough, or a custom connection is worth it.
