SOS Pay is SOS Inventory’s online payment portal for credit card and ACH (electronic check) processing. It is a fee-based service that is an add-on option for subscribers to SOS Inventory. To subscribe, obtain more information about, or obtain assistance in using SOS Pay, contact Support.
Once subscribed, a company administrator must set up SOS Pay in SOS Inventory before credit card and ACH processing can be performed. Refer to the SOS Pay setup checklist for details.
Subscribers can access the SOS Pay list via a link in the upper right corner of the Payments list (Operations > Sales > Payments), as shown in the screenshot below.

Shown below is the SOS Pay list, which works in tandem with MerchantTrack, SOS Pay's online payment portal for credit card and ACH transaction processing. The SOS Pay list is SOS Inventory's record of all MerchantTrack transactions. The link to the MerchantTrack payment portal is also in the upper right corner of the SOS Pay list.

Important differences exist between MerchantTrack transactions on the SOS Pay list and payment transactions on the Payments list. The distinguishing characteristics of each are summarized in the subsections below.
New SOS Pay subscribers receive an email invitation to register for SOS Inventory's online training course on this feature. The Help Center's video tutorial, Getting started with SOS Pay, is an additional introductory resource.
Transactions on the SOS Pay list DO NOT sync to QuickBooks Online. Depending on the associated transaction that created the MerchantTrack payment, SOS Inventory will either sync the transaction to QuickBooks Online or record the payment as a journal entry in QuickBooks Online.
SOS Pay reports are not run in SOS Inventory. Depending on the type of report, they are available in either MerchantTrack or QuickBooks Online. MerchantTrack offers a variety of reports on credit card and ACH transactions, merchant statements, and fees. Use QuickBooks Online for other types of payment reports. See the SOS Pay MerchantTrack portal page for more information about the reports available in MerchantTrack.
