Integrate PHP MYSQL ecommerce website with POSSIM inventory and MYOB accounting

[skyfire]

I'm looking for help/scripts/suggestions/anything regarding full integration of an ecommerce website, POSSIM POS and inventory and MYOB accounting software.  The ecommerce site will be created using PHP and MYSQL. 

 

How complex is this problem?  Do POSSIM and MYOB allow for integration?

 

I appreciate any help!  Thanks

i think the POS system might actually be called e-posim.  I'm just trying to figure out what my client said...
