The products are made for companies with a few scanners, a few technicians, a few sales people or a few dozen employees: too small for the big suites, too big to keep retyping everything. What you need is the same for all four:
- SAP Business One 10.0 with the Service Layer enabled. KScan, KHRM and KCRM run on SQL Server and SAP HANA, alongside the B1 client or the Web Client; KFSM on SQL Server first, HANA later. KHRM also works without SAP at all.
- A Windows server next to SAP; the SAP server itself is fine.
- Android devices: handheld scanners or phones for KScan, phones or tablets for KFSM. No iOS; at most later, on request. KHRM and KCRM run in the browser, on PC and on any phone.
- Your own administrator or B1 partner for the installation, with the manual.
Want to read up first? The knowledge base has short guides on scanning without a WMS, which scanners work, SAP licences for scanner users, field service in B1 and GS1-128.
