ERP Integration: Synchronizing B2B Sales with Logo, Mikro, and SAP

ERP integration automatically posts the orders, customer account movements, and collections generated on your B2B platform into your accounting/ERP software, and reflects stock, customer account balances, and pricing from the ERP back into the B2B platform. It is a bidirectional data bridge. The stock and prices your dealer sees on screen are identical to the values in your accounting records at that moment.

Without integration, the most common picture looks like this: the sales team takes an order on the B2B panel, then manually re-enters the same order into Logo or Mikro. In the process, one line item's price is copied incorrectly, another item is actually out of stock, and a third dealer has long since exceeded its risk limit. Double data entry doesn't just waste time; it produces errors. This is the source of the hours spent chasing discrepancies between sales and accounting during the month-end reconciliation.

In a properly built integration, the flow advances on its own. The moment an order is approved, an invoice/delivery note is created in the ERP, stock is reserved, and the customer account balance is reduced; when payment is received, the collection is posted to the relevant customer account. Human intervention is needed only for exceptions, that is, for line items that don't match automatically. The operations team is freed from data entry and can focus on its real work: sales and customer relationships.

The first step in planning a sound integration is to clarify which data will flow in which direction. In a typical B2B setup, the flow is bidirectional, but each data type has its own direction and priority. Deciding this up front prevents conflicting records and 'which system is right?' debates down the line.

The typical data flowing from the ERP to the B2B platform is as follows: product/stock records and current stock quantities, price lists (often multiple lists and tiered pricing), customer account records, customer account balances, and risk/limit information. The rule here is usually that the ERP is the master source; on a product's stock or a dealer's limit, the ERP has the final say. The data flowing from the B2B platform to the ERP, in turn, consists of approved orders, the invoice/delivery note records generated from them, and collection movements.

A concrete example: a dealer orders 200 units of a product from the B2B panel. The system first checks the current stock in the ERP; if stock is sufficient and the customer account's risk limit allows, it approves the order. At this point, stock is reserved in the ERP and an invoice record is created. When the dealer pays via 3D Secure or their wire transfer lands in the bank account, the collection is automatically allocated to the relevant customer account; the balance is updated simultaneously in both the panel and the ERP. Because you enter the data at a single point, the two systems never diverge from each other.

Every ERP has a different integration gateway; there is no one-size-fits-all method. Logo (Go, Tiger, and GO Wings editions) generally connects via REST-based web services and official integration interfaces; object-based access and ready-made services are common in this ecosystem. With Mikro, integration usually runs at the database level or through the service/interface layer that Mikro provides. SAP carries the standards of the enterprise side: RFC/BAPI calls, OData services, and often an intermediate integration layer (middleware). Systems like Netsis, Nebim, Paraşüt, and Dia also have their own REST APIs or service interfaces.

In practice, the connection architecture falls into three main patterns. The first is direct API/service integration: the B2B platform calls the ERP's web service, works in near real time, and is the preferred method for modern editions. The second is the middleware pattern: an independent bridge is placed in between that handles data transformation, error handling, and logging without altering the source systems; it is especially useful with systems like SAP or when integrating multiple sources at once. The third is file-based transfer: periodic XML/CSV exchange for older editions with limited API support; it isn't real time, but it's a practical solution on legacy infrastructures.

B2BPro doesn't require you to change your ERP; it adds a B2B sales layer on top of your existing infrastructure. The connection is established using the most suitable method your system offers (API, service, or middleware); customer account records, stock codes, price lists, and warehouse codes are mapped between the two systems; and which data flows in which direction is defined item by item. The integration infrastructure is ready for common systems such as Logo, Mikro, SAP, Netsis, Nebim, Paraşüt, ETA, and Dia.

Most integration projects stumble not on the technical connection but on data mapping. The reason is simple: the two systems name the same thing differently. If the customer account code in the ERP and the dealer record in the B2B platform, the stock code in the ERP and the product in the panel, or the warehouse code in the ERP and the location in the B2B platform don't map one to one, the bridge will carry the wrong data even if it works technically. The most critical phase of the setup is cleaning up the codes in the source system and building the cross-mapping table correctly.

The most common pitfalls are these: the same product appearing under two different codes in the ERP (duplicate records), failing to clarify the VAT-inclusive/exclusive difference in price lists, unit conversions (case/unit) not matching across the two systems, and customer account mapping done by name rather than by tax number, causing dealers with similar names to get confused. Each of these errors turns into a wrong invoice or an offset against the wrong customer account once you go live. Catching them during the mapping phase is far cheaper.

The way to reduce these risks is a disciplined setup process: first preparing the codes and the mapping table, then validating with real data in a test/sandbox environment, and finally going live in stages. It is also essential that records which don't match automatically aren't lost, but are queued separately for approval; the real danger isn't that an error occurs, but that it slips by silently. In B2BPro, the synchronization status, transferred records, and any errors are monitored from a single panel; unmatched line items land in an approval list rather than being processed automatically.

The value of ERP integration isn't limited to data consistency; when set up correctly, it also accelerates cash flow. That's because the wait times in the sales-collection-accounting chain are eliminated. In the classic flow, an order is taken, passed to accounting, an invoice is issued, payment is awaited, and when payment arrives someone manually posts it to the customer account. Between every step there are people and time. In an integrated flow, these steps are triggered automatically, one after another.

In B2BPro, this chain is connected end to end. The dealer's order goes through the B2B panel; thanks to ERP integration, the invoice/delivery note is created in accounting and stock is reserved. On the payment side, two mechanisms come into play: with a customer-account-based payment gateway and a 3D Secure dealer payment link, the dealer can pay securely from their card; or, thanks to bank account integration, an incoming EFT/wire transfer is automatically allocated to the correct customer account according to rules such as IBAN or tax number. The moment payment is confirmed, the relevant order can be released for shipment.

For example, a dealer makes their payment via the payment link on Friday evening. In an integrated setup, the payment is posted to the customer account instantly, the order is approved automatically, and on Monday morning the warehouse begins shipment directly; no one needs to match receipts or ask accounting 'did the payment come in?' As the dead time between collection and shipment shrinks, cash returns to the company faster, and end-of-day reconciliation is completed within minutes.

A successful ERP integration project doesn't want surprises, it wants a plan. The first step is to clarify the scope: which data will be synchronized, in which direction will it flow, and which system will have the final say on which data? When these decisions are put in writing, they form a common ground that everyone can refer to throughout the project. The second step is data hygiene; cleaning up duplicate customer account and stock records, standardizing codes, and preparing the mapping table must all be completed before going live.

The third step is establishing the connection and validating it in a test environment. In testing done with real data but in an isolated environment, you confirm that prices, stock, invoice line items, and customer account allocations all flow correctly. The fourth step is staged go-live and monitoring: rather than turning on the full load on day one, advancing while closely tracking the synchronization status and the error queue reduces risk. The final step is continuity; integration is not something you set up and forget, but a living system that is monitored through reports and whose rules are updated when needed.

In B2BPro, the B2BPro team carries out the setup, data mapping, training, and support at every step of this roadmap. The entire flow runs over secure connections compliant with the KVKK (Turkey's data protection law), PCI DSS, ISO 27001, and 3D Secure standards. If your ERP is on the list, you get ready-made infrastructure; if you use a custom system, you get a setup evaluated according to your needs; either way, you can synchronize your B2B sales end to end without changing your existing accounting software.
