E-commerce and integrations

Picture a typical Turkish online seller at nine in the morning. Someone opens the Trendyol seller panel, retypes last night's orders into Logo, switches to the e-invoice provider's portal to issue e-Arşiv invoices one at a time, prints labels from the Yurtiçi Kargo screen and pastes tracking codes back into Hepsiburada by hand. By lunchtime not a single parcel has left the building. Sales are healthy; the systems simply do not know about each other. That gap is what we close. Apply links your storefront, the marketplaces, your accounting software, your chosen e-invoice provider, your payment institution and your carriers, so an order travels from basket to booked invoice without a human relay. Everything is done remotely, which means a boutique label in Istanbul and a home textiles maker in Denizli get exactly the same service.

What we connect

Each of the four services removes one particular chore: raising invoices manually, correcting stock channel by channel, matching bank receipts to orders and producing carrier labels one parcel at a time.

Tell us about your store

What moves, and how often

Real-time sync of everything sounds attractive and rarely works. Marketplace APIs throttle heavy callers, and an accounting server in the back office crawls when it is queried non-stop. So every kind of data gets a rhythm of its own.

Sellable stock

From the warehouse to every channel, every five to fifteen minutes. Ahead of the November sales season and the days before a bayram we tighten the interval and hold back a buffer on each channel, so the last unit is never sold twice.

Prices

Several times a day, or the moment a price change goes live. Separate lists for your own site, each marketplace and your dealers, each with a floor price so that nothing sells at a loss once commission and shipping are taken off.

Descriptions, images, attributes

Overnight. Bulky catalogue updates slow down the machine running Logo or Mikro, and the accounts team ends up waiting. Marketplace category and attribute mappings are refreshed in the same night-time job.

Orders

Straight to accounts and the warehouse once payment clears. A Hepsiburada order placed at 01:00 is sitting on the picking list when the warehouse team clocks in, untouched by anyone.

Invoices and tracking

Back from the integrator and the carrier to the store and the marketplace. Buyers find the e-Arşiv invoice link and tracking code in their account, and the marketplace receives its dispatch confirmation in time, which lowers the risk of late-shipment penalties.

Wire up a messy catalogue and you just make mistakes faster. If one barcode sits on two different products, sizes read “M” in one place and “Medium” in another, and every colour variant has its own stock card, nothing lines up with the category attributes Trendyol and Hepsiburada expect. Stock lands on the wrong item and orders fail to match. So the first task is putting SKUs, barcodes and the variant structure in order. A few days of tidying removes the small corrections that would otherwise recur daily for months. Skip it, and you discover on the busiest November night, through a customer complaint, that the same item has been sold twice.

How a project runs

Trials happen in a test company inside your accounting software, in the integrator's test environment and in the sandbox accounts of payment and carrier partners. A faulty e-invoice in the live system means cancellation, a return invoice and extra hours for your accountant.

01

Follow one order

On a video call we trace a genuine order from basket to the money arriving in your bank, and flag every point where a person currently copies, forwards or double-checks something.

02

Agree the rules with your accountant

Which orders get an e-Fatura and which an e-Arşiv, KDV rates, series and numbering, partial refunds, marketplace commission invoices, and how in-store pickups relate to your cash register POS. All written down before anything is configured.

03

Full dress rehearsal

Order, card payment in instalments with 3D Secure, invoice, label, tracking, return and return invoice, run end to end in the test environments. Nothing goes live until every figure reconciles.

04

Go live, then watch closely

We switch the syncs on, set up email alerts for failures and, for the first month, lay store, marketplace and ledger figures side by side every week.

Frequently asked questions

Usually, yes. Packaged connectors shift stock and orders reliably but tend to fall short on the accounting side, on bespoke pricing rules or with more than one warehouse. We start by looking at what your tool already does well; filling the missing piece is normally cheaper than replacing it. If the tool exposes an API we use it, otherwise we work with scheduled file exchange.

This is where most sellers struggle. A Trendyol or Hepsiburada settlement nets sales, refunds, commission, shipping share and service fees into one payout, so the amount hitting your bank never matches any single order. We build a flow that reads the settlement statement line by line and creates each sale, return and deduction as its own entry in Logo, Mikro or Paraşüt. Commission invoices the marketplace raises against you enter the same flow as expenses. Which chart-of-accounts codes to use is something you settle with your mali müşavir.

No. The store keeps selling against the last known stock level, orders wait in a queue and are processed in sequence once the link is back. Your nominated contact and our engineers get an email alert. By Monday morning it is clear what happened, what caught up on its own and whether anything needs a manual look, before the first customer asks. If the outage is on the integrator's end, invoices queue too and the numbering stays intact.

Neither is available to merchants established in Turkey, so we do not recommend them. For foreign cards we look at what iyzico, PayTR or Craftgate offer for international acceptance, or at your bank's virtual POS. When you sell through Amazon or Etsy the marketplace collects payment, so the real job on your side is getting orders and refunds into the books correctly.

That depends on how many systems are involved, how tidy the product data is and whether usable ready-made plug-ins exist. A WooCommerce shop with Paraşüt, iyzico and one carrier is far simpler than a Logo Tiger set-up with three warehouses and five marketplaces. After an initial review you get a fixed quote for the project; ongoing care afterwards is billed at €55 per hour plus VAT or covered by a service plan.

Only remotely, over encrypted connections and through restricted accounts that you create and can disable whenever you like. We do not visit, do not sell hardware and do not pack parcels. If something physical has to be done to a server, a member of your staff gets step-by-step instructions from us.
