Frequently asked questions

What kind of ecommerce customers does Mehanna Advisors support?

Mehanna Advisors serves ecommerce customers of all shapes and sizes including online-only, multi-channel, and direct-to-consumer brands.


What types of ecommerce platforms do your customers use?

We have customers using every major ecommerce platform, including Shopify, Amazon, WooCommerce, Magento, BigCommerce, and Salesforce Commerce Cloud.


As an example, for an unprofitable 5-person tech startup that has less than $5M in annual revenue with roughly 80% of time being spent on qualifying R&D activities, and average salary of $100k/year, the credit might be between $20k to $60k. Mehana advisor’s fee is a small percentage of the total qualifying R&D expense and easily pays for itself by securing the R&D Tax Credit for you.

Do you handle inventory?

Mehana advisors makes inventory updates in your financial statements every month based on data provided by either the customer or the source of truth for customers’ inventory (e.g. a system like Tradegecko).

What system do you recommend for online store inventory?

We work with a variety of inventory management solutions but recommend Tradegecko and Skubana based on their simplicity of use and ability to scale.


Your core plan includes connections to four financial institutions, but my business uses more than four. Does that mean I'm a Plus customer?

For simple ecommerce companies that have more than 4 financial institutions, we offer the option of adding additional financial institutions to your Core subscription for a flat fee.


Does Mehanna Advisors handle sales tax?

We don’t currently offer sales tax services, but recommend TaxValet for an end-to-end sales tax solution.

How does Mehanna calculate Cost of Goods Sold?

There are three different ways we calculate Cost of Goods Sold (COGS), depending on your business:

  • For product COGS (i.e. the actual cost of the items sold), we base our calculations on inventory information you share with us.
  • For Merchant Fees and Shipping COGS, we track your metrics automatically and categorize your variable expenses there.
  • For other variable costs you wish to track as COGS, we work with you to create accounts and categorization rules to implement this for your business.

How does Mehanna handle returns/gift cards?

Our automation pulls this information directly from your store, ensuring you have accurate figures for both items month–over–month.


Does Mehanna have the ability to break out Amazon/Shopify fees in the P&L?

Yes, Mehanna can separate our merchant fees of all types in your Profit and Loss statements.


Does Mehanna break down revenue and costs by product and/or channel?

Yes, Mehanna can break out your revenue and costs in your Profit & Loss statements by product and/or channel.
