What is considered COGS for service-based businesses like accounting firms?
I run a small accounting practice and I'm trying to understand how to properly categorize my expenses. Specifically, I'm confused about what counts as Cost of Goods Sold (COGS) in a service business like mine. For example, I purchase tax preparation software every year that I use to file returns for clients - would this be considered COGS or just a regular business expense? I've been categorizing it as a regular expense but my colleague insists it should be COGS since it's directly tied to providing our service. This has implications for my gross profit calculations and I want to make sure I'm doing it right for 2025 taxes. Also wondering what other expenses in accounting would fall under COGS vs. regular business expenses? Thanks for any clarity!

In service-based businesses like accounting, COGS typically includes costs directly related to providing your services. The tax software you use to prepare returns would generally be considered a COGS because it's directly tied to the service you provide to clients. Think of it this way: if you weren't filing tax returns for clients, would you need that specific software? If the answer is no, then it's likely a direct cost of providing your service. Other examples of COGS for accounting practices might include: - Staff wages for those directly performing client work - Subcontractor fees for work directly billed to clients - Research materials specifically needed for client projects - Cloud storage costs for client documents - Per-client software licensing fees Regular business expenses would be things like office rent, marketing, administrative staff, general liability insurance, etc. - costs you'd incur regardless of how many clients you serve.

•Thanks for this breakdown. I'm wondering about staff wages though. My understanding was that only the wages of people directly producing something could be COGS. Like in a bakery, the baker's wages would be COGS but not the cashier's. In accounting, wouldn't all our work be considered "overhead" since we're not making a physical product?

•For service businesses, the "product" is actually the service itself, so the labor directly involved in providing that service is analogous to the direct labor in manufacturing. So an accountant working directly on client tax returns would be considered part of COGS, just like a baker making bread. You're right that in a traditional manufacturing context, only production wages count as COGS. But in service businesses, we adapt the concept. The key distinction is between labor directly involved in delivering the service to clients versus supporting roles. A receptionist or marketing person in your accounting firm would be overhead, not COGS, because they don't directly perform the billable service.

I went through the exact same confusion with my accounting practice last year! After hours of research and getting nowhere, I found this AI tool called taxr.ai (https://taxr.ai) that specifically helps with business expense categorization. I uploaded my expense list and it immediately identified which items should be COGS vs. operating expenses for a service business. For tax software specifically, it confirmed it should be COGS if it's directly used to generate client deliverables (like completed tax returns). The tool explained that in service businesses, COGS includes direct costs that would not exist if you weren't providing the service - which for accountants includes specialized software licenses, direct labor costs, and even things like secure client portal subscriptions. Saved me so much time trying to figure out the proper categorization!

•How accurate is this tool? I'm always skeptical about AI tools making tax determinations. Does it explain the reasoning behind its categorizations? I've had issues with other systems that just make black-box decisions without explanation.

•Does it work for other service businesses too? I have a law firm and struggle with similar COGS issues - wondering if it would help me categorize case management software, legal research subscriptions, etc.

•The accuracy has been really good in my experience. It doesn't just categorize - it actually explains the tax reasoning behind each decision, citing relevant IRS publications and tax court cases. That's what impressed me most - I could see why it was making each recommendation. It absolutely works for other service businesses including law firms! It has specific modules for different professional services. For law firms, it would help categorize exactly those items you mentioned - case management software, legal research subscriptions, and even paralegal time spent directly on client matters. The tool understands the nuances between different types of service businesses.

Just wanted to follow up - I tried taxr.ai after seeing it mentioned here and it was incredibly helpful for my law practice! I uploaded my expense list and it accurately sorted everything between COGS and operating expenses. For example, it correctly categorized our Westlaw subscription as COGS since we use it directly for client research, but put our general office management software under regular expenses. The explanations for each category were detailed and referenced relevant tax guidance. This cleared up years of confusion for me about handling service business expenses properly. Definitely worth checking out if you're struggling with this!

After struggling for weeks trying to reach someone at the IRS to get clarity on COGS classification for my consulting business, I finally used Claimyr (https://claimyr.com) to get through to an actual IRS agent. You can see how it works here: https://youtu.be/_kiP6q8DX5c The service got me connected to a real IRS representative in about 15 minutes when I had been trying unsuccessfully for days. The agent clarified that for service businesses, COGS should include direct costs that would disappear if you stopped providing services. For my situation, they confirmed that specialized industry software used to deliver client work should be classified as COGS, not general overhead. Huge relief to get this official clarification directly from the IRS!

•How does this actually work? I don't understand how a third-party service can get you through to the IRS faster than calling yourself. Sounds kind of suspicious honestly.

•Yeah right. I've tried EVERYTHING to get through to the IRS and nothing works. They're just impossible to reach. I seriously doubt this service could do anything different than what I've already tried multiple times.

•It works by using an advanced system that navigates the IRS phone tree and waits on hold for you. When an agent finally picks up, you get a call connecting you directly to them. It's not bypassing any official channels - it's just handling the hold time so you don't have to stay on the phone for hours. I was skeptical too, but the difference is they have technology specifically designed to stay on hold and navigate the complex phone systems. I've spent hours trying to reach someone manually and gave up. With this, I was literally able to go about my day and then got connected when a human finally answered. No magic, just smart automation of the most frustrating part of calling the IRS.

I need to eat my words! After posting my skeptical comment, I decided to try Claimyr anyway out of desperation since I had a pressing question about COGS for my video production business. I could NOT believe it actually worked! After trying for weeks to reach someone at the IRS and always getting the "call volume too high" message, I got connected to an agent in about 25 minutes. The agent confirmed that my editing software and contractor editing fees should indeed be classified as COGS since they're directly tied to producing client deliverables. This has been a huge tax question hanging over my head for months, and I finally got it resolved. Honestly shocked that something actually worked as advertised.

I think there's an important distinction being missed here about COGS for service businesses. The IRS doesn't technically use "COGS" terminology for pure service businesses on Schedule C - they use "Cost of Labor" instead. If you're selling products AND services, then you'd have both COGS and cost of labor. So for a pure accounting practice, the software would go under "Other Expenses" and you'd detail it there. But if you're also selling tax guides or products along with your services, then you'd have a COGS section for those physical items.

•Are you sure about this? I've been filing Schedule C for my consulting business for years and I definitely use the COGS section for direct service costs. My CPA specifically sets it up this way. Can you point to where the IRS says service businesses should only use "Cost of Labor"?

Zara Mirza
•You're right to question this - I should have been more precise in my explanation. While the Schedule C form does have a specific "Cost of Labor" line, service businesses can and do use the COGS section for direct costs. What I was trying to convey is that the IRS treats service businesses differently than product-based businesses in some contexts. The key is consistently categorizing direct costs related to providing your service. If your CPA is using the COGS section for your direct service costs, that's a standard and acceptable practice. The most important thing is that you're capturing all direct costs properly and consistently, whether they're classified in COGS or itemized separately, to ensure you're calculating your true gross profit.

Quick question - I use QuickBooks for my legal practice and it automatically categorizes some expenses. Should I trust its default categorizations for COGS vs. operating expenses? It put my Lexis subscription as a regular expense but I'm thinking it should be COGS based on this discussion.

•Don't trust the default QuickBooks categories for this! They're super generic and not tailored to specific service businesses. I had to completely reconfigure mine for my physical therapy practice. For legal services, definitely recategorize your Lexis subscription as COGS since it's directly used for client work.

This is such a helpful discussion! I'm dealing with the same issue in my graphic design business. Based on what I'm reading here, it sounds like my Adobe Creative Suite subscription should be COGS since I use it directly to create client deliverables, but my general business insurance and office rent would be operating expenses. One thing I'm still confused about though - what about equipment depreciation? I have a high-end computer and printer that I use exclusively for client work. Would the depreciation on those assets be considered COGS or just regular depreciation expense? It seems like they're directly tied to service delivery, but depreciation feels different from the software and labor costs everyone's been discussing. Also wondering if anyone has experience with mixed-use expenses - like if I use design software 80% for client work and 20% for my own marketing materials, how should that be allocated?

•Great questions! For equipment depreciation, you're right that it feels different from other COGS items. Generally, depreciation on equipment used directly for client work (like your computer and printer) would still be considered part of your cost of providing services, so it could be classified as COGS. The key test is the same - would you need this equipment if you weren't serving clients? For the mixed-use allocation, you're on the right track with the 80/20 split. You can allocate based on actual usage - so 80% of your Adobe subscription would go to COGS and 20% to general business expenses. Keep good records of how you determined these percentages in case of an audit. Some people track this monthly if usage varies, others use annual estimates if it's fairly consistent. The IRS is generally fine with reasonable allocation methods as long as you're consistent and can justify your approach. Just make sure whatever method you choose, you apply it consistently across similar expenses and tax years.

This thread has been incredibly helpful! I'm a freelance marketing consultant and have been struggling with the same COGS classification issues. Based on this discussion, I'm now realizing that several of my expenses should probably be reclassified. For example, I pay for various analytics tools (Google Analytics 360, SEMrush, Ahrefs) that I use exclusively to analyze client campaigns and generate reports. These seem like they should be COGS since I wouldn't need them if I wasn't serving clients. Same with my project management software that I use to coordinate client deliverables. What's interesting is how this changes the gross profit calculation significantly. I've been showing lower gross margins than I should because I was putting direct service costs in operating expenses. This actually makes my business look more profitable at the gross level, which is important for potential investors or lenders who focus on gross margins as a key metric. One follow-up question - for annual software subscriptions, do you spread the COGS impact across the year, or record it all when you pay the annual fee? I typically pay most of my software subscriptions annually in January, so it creates a big expense hit in Q1 if I don't spread it out.

•You're absolutely right about those analytics tools being COGS! As a fellow service provider, I've found that anything you use exclusively to deliver client results should definitely be classified that way. It's eye-opening how much it changes your gross margin picture once you get the categorization right. For the annual subscription timing question, you should definitely spread it out over the year rather than taking the full hit in Q1. This is called "matching" the expense with the revenue it helps generate throughout the year. Most accounting software can handle this automatically - you'd record the payment as a prepaid expense initially, then amortize it monthly. So if you pay $1,200 for an annual SEMrush subscription in January, you'd expense $100 each month as COGS rather than the full $1,200 in January. This gives you a much more accurate monthly picture of your true costs and profitability.

This discussion really highlights how confusing COGS classification can be for service businesses! I'm a web developer and have been wrestling with similar questions. Based on what everyone's shared here, it seems like the key principle is whether the expense directly contributes to delivering client services. For my business, this would mean my hosting costs for client websites, domain registrations, and development software licenses (like my IDE subscriptions) should be COGS. But my general business website hosting, accounting software, and office utilities would be operating expenses. One area I'm still uncertain about is professional development. I spend money on online courses and certifications to stay current with new technologies that I then use for client projects. On one hand, this knowledge directly improves the service I provide to clients. On the other hand, it feels more like an investment in my general capabilities rather than a direct cost of current service delivery. Has anyone dealt with classifying continuing education expenses in this context? I'm thinking it probably goes under operating expenses since it's more about maintaining overall business competency rather than being tied to specific client deliverables, but I'd love to hear other perspectives.

•You're right to be thoughtful about this distinction! In my experience, professional development and continuing education typically fall under operating expenses rather than COGS, even though the knowledge gained benefits client work. The key difference is timing and directness - COGS should be tied to current service delivery, while education is more about building future capacity. Think of it this way: if you took a course on React development in January but didn't use that knowledge for any client projects until June, it wouldn't make sense to classify it as a cost of goods sold when you actually learned it. The education is an investment in your business capabilities that will benefit many future projects over time. However, there might be exceptions for very specific training. For example, if a client requires you to get certified in their proprietary system and you bill them for that certification cost, then it could arguably be COGS for that specific engagement. But general skill-building courses, conference attendance, and broad technology certifications are better classified as operating expenses under professional development or education. Your hosting costs, domain registrations, and IDE subscriptions are spot-on for COGS classification though - those are directly tied to current client deliverables.

As someone who runs a small marketing consultancy, I've found this thread incredibly enlightening! The distinction between COGS and operating expenses has always been fuzzy for me in service businesses, but the "would you need this if you weren't serving clients" test really clarifies things. For my business, this means my CRM software (since I use it to manage client relationships and deliverables), social media management tools for client campaigns, and even my freelance contractor payments for client work should all be COGS. But my business insurance, office rent, and general administrative tools would remain operating expenses. What really clicked for me is how this affects financial analysis. I've been presenting artificially low gross margins to potential partners because I was miscategorizing direct service costs. Getting this right isn't just about tax compliance - it's about understanding the true economics of your service business. One practical tip: I started keeping a simple spreadsheet where I list each recurring expense and ask myself that key question - "Would I still pay for this if I had zero clients?" If the answer is no, it goes in COGS. If yes, it's an operating expense. This has made the categorization process much more systematic and defensible.

•That spreadsheet approach is brilliant! I'm definitely going to implement something similar for my consulting practice. The "zero clients" test you mentioned really simplifies what can feel like a complex decision tree. I've been overthinking this whole COGS classification issue, but your systematic approach makes it much more manageable. It's also a great point about how this affects how you present your business to partners or investors - showing accurate gross margins is crucial for demonstrating the real profitability of your service delivery model. Thanks for sharing that practical tip! Sometimes the simplest solutions are the most effective.

This has been such a valuable discussion! As someone who just started my own freelance content writing business, I've been completely confused about how to categorize my expenses. The "would you need this if you weren't serving clients" test that several people mentioned is incredibly helpful and much clearer than the vague guidance I've found elsewhere. For my business, this means my Grammarly Premium subscription, plagiarism detection software, and industry research tools would be COGS since I use them directly to create client deliverables. But my general business website, accounting software, and liability insurance would be operating expenses. I'm particularly grateful for the discussion about annual software subscriptions and spreading the cost throughout the year rather than taking the full expense hit upfront. That makes so much sense for getting an accurate monthly view of profitability. One question I still have - what about networking events or professional association memberships? I attend industry conferences primarily to find new clients and stay current on trends that help me serve existing clients better. These feel like they're somewhere between direct service costs and general business development. Any thoughts on how these should typically be categorized?

•Welcome to the community! Great question about networking events and professional associations. Generally, these would fall under operating expenses rather than COGS, even though they indirectly benefit your client work. Here's why: networking events and memberships are more about business development and maintaining industry knowledge rather than being direct costs of producing current deliverables. Think about it this way - if you attended a conference in March but didn't land any new clients or use specific knowledge from it until months later, it wouldn't make sense to classify it as a cost of the goods/services you're selling today. These expenses are investments in future business growth and general professional competency. The key distinction is that COGS should be tied to current service delivery, while networking and professional development support your overall business capacity over time. So I'd categorize conference fees, association dues, and networking events under "Professional Development" or "Marketing/Business Development" in your operating expenses. Your categorization of Grammarly, plagiarism detection, and research tools as COGS is spot-on though - those are directly used to create the content deliverables your clients are paying for. You're definitely thinking about this the right way!

This thread has been incredibly helpful! I'm a freelance photographer specializing in corporate events and headshots, and I've been struggling with expense categorization for my Schedule C. The "would you need this if you weren't serving clients" test is a game-changer. It makes it clear that my Adobe Lightroom/Photoshop subscription, professional camera equipment depreciation, and cloud storage for client galleries should all be COGS since I wouldn't need these if I had zero clients. But I'm curious about travel expenses. When I travel to shoot destination weddings or corporate events, the travel costs are directly tied to delivering that specific service. Would airfare and hotel stays for client shoots be considered COGS, or do they typically go under travel expenses in the operating section? Also wondering about backup equipment - I maintain duplicate camera bodies and lenses specifically so I never have to cancel a client shoot due to equipment failure. These backups sit unused most of the time but are essential for reliable service delivery. Should the depreciation on backup equipment also be classified as COGS? Thanks for all the insights everyone has shared - this is exactly the kind of practical guidance that's so hard to find elsewhere!
