Back-up Plan and Risk Management. Businesses couldn't afford having downtimes, as these so-called "technical difficulties" spell thousands of pesos gushing out of the company's pockets. "You must have redundancy in your server, because it's hard to be caught without a backup plan," Galit shares. "Your boss will likely blame you and ask, 'Why is there no back up?'"

BIR Policies. The Bureau of Internal Revenue is wiser now, according to Galit. "They bring in IT people to process accreditation applications, and oftentimes, they are the ones who are persistent," he explains. Galit advises potential applicants to answer questions straightforward about the system, and be prepared with all the necessary requirements.

Integration with other systems and devices. POS systems do not comprise the software only, but the peripherals and devices as well. Galit says it should be able to integrate well with touchscreen panels, printers, displays, and card readers, among others. "POS systems should also be able to integrate with existing systems, such as financials, because they need the data as well," he adds.

Environmental Safety. Green is the new black, so to speak. Companies often include sustainability agenda into their business plans, so POS systems should also be able to comply with these. Less power consumption, as well as less waste of the POS system can help the green efforts of the company.
