What does supplier complexity really cost you?

June 10, 2026

Seve­ral sup­pli­ers may seem eco­no­mic­al at first glan­ce. In prac­ti­ce, howe­ver, each addi­tio­nal inter­face crea­tes coor­di­na­ti­on issues, appr­ovals, delays, and deli­very errors – cos­ts that do not appear in tra­di­tio­nal offers. With the new com­ple­xi­ty cost cal­cu­la­tor from KOMOS, you can esti­ma­te online the hid­den cos­ts that the sup­pli­er com­ple­xi­ty in your pro­ject cau­ses – based on your own input.

Hidden costs arise at the interfaces

In many manu­fac­tu­ring pro­jects, indi­vi­du­al pro­cess steps are con­side­red sepa­ra­te­ly: deve­lo­p­ment, stam­ping, tur­ning, injec­tion mol­ding, coa­ting, assem­bly. The actu­al addi­tio­nal cos­ts ari­se. bet­ween the­se steps.

Every han­do­ver bet­ween two sup­pli­ers is an inter­face. It gene­ra­tes ques­ti­ons, coor­di­na­ti­on, docu­men­ta­ti­on, track­ing of dead­lines, qua­li­ty checks, and com­plaints. The­se inter­face cos­ts strain pro­ject bud­gets, inter­nal capa­ci­ties, and deli­very dead­lines.

The KOMOS com­pu­ter takes into account, among other things:

  • Num­ber of par­ti­ci­pa­ting sup­pli­ers and inter­faces
  • inter­nal voting hours and pro­ject dura­ti­on
  • Chan­ge rounds and release loops
  • Delays due to lost pro­ject weeks
  • Com­plaints and qua­li­ty cos­ts at deli­very points

 

Optio­nal­ly, sel­ect your indus­try – such as medi­cal tech­no­lo­gy, auto­mo­ti­ve, smart home or elec­tro­nics – for a more appro­pria­te clas­si­fi­ca­ti­on.

An exam­p­le of cal­cu­la­ti­on: A com­po­nent assem­bly pro­ject with five sup­pli­ers is divi­ded into four real deli­very points. Alre­a­dy two coor­di­na­ti­on hours per deli­very and month add up to near­ly 100 inter­nal hours over a twel­ve-month peri­od – wit­hout coun­ting a sin­gle delay or com­plaint. It is the­se items that the cal­cu­la­tor makes visi­ble.

One interface instead of many transfers

KOMOS brings tog­e­ther key manu­fac­tu­ring and assem­bly steps under one roof. This redu­ces inter­faces, shor­tens paths, and cle­ar­ly assigns respon­si­bi­li­ties.

The cal­cu­la­tor shows the impact of sup­pli­er com­ple­xi­ty on your pro­ject cos­ts – and whe­re inte­gra­ted manu­fac­tu­ring offers poten­ti­al savings.

You can recei­ve an initi­al assess­ment wit­hout regis­tering. We will send you the detail­ed ana­ly­sis, inclu­ding cost dri­vers and a com­pa­ri­son of indus­tries, upon request via email.
