Gig Summary
About this gig
Connect SAP Business One to your other systems through the Service Layer or REST APIs: portals, banks, CRMs, warehouse and in-house apps.
SAP Business One developer for 7+ years, with clients in 13 countries. I build reliable SAP B1 integrations on SQL Server and SAP HANA.
What I can build for you:
- Service Layer and REST API integrations, in one or both directions
- Sync business partners, items, prices, stock, orders and invoices
- Vendor, customer and employee portals connected to SAP B1
- Bank, payment and third-party API connections
- Scheduled sync jobs with error logs, retries and duplicate protection
How I work:
1. You share your B1 version, database and the systems to connect
2. I confirm the scope, data mapping and a fixed price
3. I build and test on your test company
4. You get the source code (you own it), setup guide and 3 months of free support
Need add-ons with new screens inside SAP B1? See my add-on gig.
Message me your B1 version and what you want to connect.

I'm Zain Abbas, founder of Kodenova, an SAP Business One developer with 7+ years of experience and clients in 13 countries. I build SAP B1 add-ons (DI API, UI API), Service Layer and API integrations, SQL Server to HANA migrations, Crystal Reports, custom portals, and AI agents and MCP servers for ERP. Recent work: SAP B1 systems handling 50,000+ orders a year for a client. I test on your test company and deliver source code you own, plus 3 months of free support. I work in English, Spanish and Arabic. Send me your B1 version and what you need.

FAQ
Do you work with both SQL and HANA versions of SAP Business One?
Yes — I develop and optimize for both SAP B1 on SQL Server and SAP HANA, including version 10.0. Tell me your version and I'll confirm the approach before we start.
How do you access my system, and is my data safe?
We agree a secure method that you control, such as your own VPN or remote desktop session, or a backup of your test company. I build and test on your test company and never need production access to develop.
Do you support on-premise and cloud-hosted SAP Business One?
Both. Whether your B1 is on-premise, on a private server, or cloud-hosted, I build add-ons and integrations that fit your deployment.
Can you integrate SAP B1 with Shopify, WooCommerce or other third-party apps?
Yes — real-time, two-way integrations via Service Layer / DI-API with Shopify, WooCommerce, CRMs, payment gateways and custom web portals.
Do I get the source code and a setup guide?
Yes. Every package includes the source code, which you own, and a short setup guide. Standard and Premium also include 3 months of free support after go-live.
How do you handle Service Layer authentication and performance under high load?
I use session pooling/token reuse and optimized queries so the Service Layer stays stable under high traffic — important for live e-commerce and multi-user setups.
