SAP Business One integration in Peru
Connect your operation to SAP B1 so invoicing and data flow on their own — no double data entry.
Many companies already run SAP Business One for their accounting and invoicing, but their customer-facing operation (sales, enrollment, e-commerce, point of sale) lives in another system. When someone has to key everything in twice, it is time to integrate.
We build the integration to measure: every transaction from your front-end system travels automatically to SAP B1 with the correct payload. We did it for a club of 50,000+ members, where every enrollment invoices itself in SAP Business One.
// what we solve
What we build for you.
Automatic invoicing
Every sale or enrollment sends its payload to SAP B1 and invoices without manual data entry.
Master-data synchronization
Customers, items, prices and stock aligned between your system and SAP.
Integration with your front-end system
Web, enrollment, e-commerce or point of sale — we connect what you already use.
Payload and error handling
Validation, retries and traceability so no transaction is lost.
Real time or batch
According to your operation: immediate submission or scheduled processes.

// how we work
From the first meeting to production.
- 01
Model the chain
Before any code: which SAP objects take part in each operation. A payment is not one object, it is business partner, invoice and applied payment — and the third one is always the forgotten one.
- 02
Access and test environment
Service Layer credentials, permissions and a test database that resembles the real one. Testing against fictional data is what makes the surprises show up in production.
- 03
Idempotent build
Sessions that renew themselves, retries that do not duplicate documents, and the reference of every document stored in your database before the send is treated as done. In an ERP with fiscal numbering, duplicating costs a credit note.
- 04
Electronic invoicing
If you issue in Peru, the chain does not end at SAP: it ends when SUNAT returns the CDR. We define which add-on triggers it and how your system reacts when the answer does not arrive.
- 05
Reconciliation by period
A cross-check between what you charged and what ended up invoiced and applied in SAP. A 200 from the Service Layer does not mean the accounting balances, and without this cross-check you find out at close.
When integrating is not worth it
If volume is low —a handful of operations a day— and somebody already keys them without effort, automating can cost more than it saves. And if your SAP installation is heavily customized with third-party add-ons touching the same documents, it is worth assessing first whether the integration will collide with them: we would rather tell you during the assessment than when duplicate documents appear.
Senior engineering
Whoever designs your system writes it. No juniors learning at your expense.
The code is 100% yours
We hand over the repository and the documentation. No lock-in.
Real cases
Not theory: systems in production, including the public sector.
// frequently asked questions
What people usually ask us.
Service Layer or DI API?
For a new web system, almost always the Service Layer: it is REST over OData and far easier to operate. They share the same data core, so objects and their properties are identical; what changes is the transport, not the model you have to respect.
How long does a SAP B1 integration take?
The technical part usually runs 4 to 8 weeks. What stretches it is getting access, a test environment resembling the real one, and clarifying which electronic invoicing add-on is in play.
Can it duplicate documents?
Not if built properly, and that is precisely the main risk. Retries duplicate when the created document’s reference is not stored before retrying; in an ERP with fiscal numbering that is not deleted, it is voided with a credit note.
What can be integrated with SAP Business One?
Invoicing (automatic transaction submission), customer and item master data, and your front-end operation flows — sales, enrollment, e-commerce or point of sale.
Real time or batch?
Both. We design immediate submission or scheduled processes according to what your operation needs.
How do you handle integration errors?
With payload validation, retries and traceability of every transaction, so nothing is lost between systems.
Does it integrate with my e-commerce or point of sale?
Yes. We connect your customer-facing system with SAP B1, whether web, e-commerce or POS.
