Hi everyone. I am a business owner, not a developer. I am looking to hire an expert ERPNext/Frappe architect for a paid project. We are an industrial parts distributor with 7,000 SKUs. I need someone to set up an ERPNext environment for Android barcode scanner guns and build a backend connection to our SAP Business One Service Layer. If you take on high-end freelance integration projects, please reply here or send me a direct message with your rates and portfolio.

Hello @Nikfarman
I would like to assist you.
Please reach out to me at seth (@) cisinlabs (dot) com
So we will discuss this in detail and will share the quote.
Thanks

Okay please connect with me and will share more details about your current need. Already worked on excat solution and confident to help you.
I am a bit confused here…
If you are SAP B1 then why do you need to use ERPNext at all?
To integrate such a feature you need to build a stand alone solution (Android or Desktop) that does the work and pushes the data to you SAP B1 service layer.

Hello,
I’m 10+year ERPNext builder with rich integration experience. May I understand more about your project before giving rates?
Best regards,
Larry
It would be better to migrate from SAP 1B to ERPNext instead of building an integration interface.
We just helped two companies in UAE to migrate to ERPNext.
One from SAP 1B and another from Oracle NewSuite.
But if you insist on saying with SAP 1B then what is suggested by @YogiYang it the approach you need to adopt.

High-performance SAP B1 Service Layer integrations and ERPNext mobile barcode scanner frontends can be engineered to your exact specifications, also, Are you looking for real-time bi-directional sync for those 7,000 SKUs, or should the Android scanners queue transactions offline to prevent warehouse delays if the SAP Service Layer experiences latency? Thanks
Hi @Nikfarman,
you’ve gotten both “why ERPNext at all?” and “just migrate everything” — I’d argue what you asked for is exactly right: ERPNext as the warehouse front-end, B1 stays the system of record. Item master + barcodes sync B1 → ERPNext (Service Layer delta pulls), stock movements flow back through an idempotent queue so retries can never double-post. With 7,000 SKUs the real work is item/UoM mapping and handling unmapped scans cleanly. Depending on your B1 license terms, floor staff booking in ERPNext instead of B1 may also save per-user costs.
Happy to detail the design. Background: ~30 years ERP integration, incl. co-authoring the original Lotus/SAP connector (LEI); Frappe/ERPNext is my primary platform today. I’d propose a fixed-price Phase 1 (item sync + goods receipt end-to-end) to validate on real data first — DM me if that sounds right.

Hello Nikfarman,
I’m a fullstack developer expert specialized in ERPNext/Frappe only. I have been doing just that since 2017. I know everything about the framework and I also manage infrastructure, if you need more details please let me know
I am ready !
Hi, I have hands-on experience with ERPNext/Frappe — including API integrations (REST, OAuth 2.0, XML-RPC) with systems like Zoho Books, Odoo, QuickBooks, Xero, and Tally, plus custom Frappe module development. I haven’t worked with SAP Business One specifically yet, but I’m confident in picking up the Service Layer integration given my API integration background. Happy to share more about my experience and discuss rates once I understand the full scope — could we set up a quick call?
Hi, we’d be happy to help with your project.
We have extensive experience with ERPNext/Frappe implementations, custom development, and enterprise integrations. We’ve developed a mobile WMS application for ERPNext with Android barcode scanner support and have successfully delivered ERPNext–SAP Business One integration projects. We also have strong experience with data migration, API integrations, and complex backend customizations.
We’d be happy to discuss your requirements and share relevant project references.

Your architecture makes sense using ERPNext as the warehouse interface while SAP Business One remains the system of record is a practical approach. One thing I want to understand is whether the barcode scanners need real-time synchronization with SAP or if an offline queue with automatic sync would also meet your warehouse workflow. That decision can significantly affect performance and reliability. Happy to discuss if you are still evaluating options.
Hi @Nikfarman — the part of this that usually decides whether it works isn’t the Service Layer integration itself, it’s what happens when the scanners lose wifi.
In a parts warehouse that will happen daily. So the design question ahead of “how do we connect to SAP B1” is: does a scan queue locally and replay when the gun reconnects, and is that replay idempotent? If a goods receipt can post twice because a scanner retried, you get phantom stock across 7,000 SKUs and nobody trusts either system afterwards. That is the failure mode I’d want closed before writing integration code.
Two related things worth deciding early: SAP B1’s Service Layer uses session-based auth that times out, and scanner guns cycling on and off will thrash sessions unless there’s a single broker holding one session rather than each device authenticating. And with SAP as system of record and ERPNext as the warehouse interface, you need a stated rule for what happens when the two disagree on stock — reconciliation is not an afterthought here, it’s the design.
Happy to write this up properly against your setup — a short scoped note on sync strategy, idempotency and the reconciliation rule, free, no call needed. If it’s useful we can talk about the build.
