Is Your Accounting Keeping Up with Your Business Growth?
Your business is built on cutting-edge technologies. But does your financial back-office feel like it’s decades old? It's a direct threat to e-commerce and SaaS business growth.
Are you struggling with data that never adds up?
Your team is spending weeks reconciling payments from Stripe and PayPal. Your Shopify sales reports are different from your P&L statement numbers. The exponential sales growth is causing exponential bookkeeping errors.
Is international expansion more of a headache than an opportunity?
The complexities of VAT and sales tax compliance are either preventing you from launching in new markets or taking months of your valuable time to figure out.
Are you making critical decisions in the dark?
You need to know if you can afford to acquire a competitor this month. You know you must find a way to extend your runway this year. But your current accountant is more focused on last year's taxes. You feel like you’re on your own when making the big calls.
The Leaks Are Deeper Than You Think
When clients approach us to solve their pressing accounting issues, we find much more hidden under the surface. Online businesses waste more cash and lose more opportunities than they realize.
You are bleeding cash through tax waste
You are paying VAT and sales taxes on some refunded orders. Your accountant fails to account for payouts to some affiliates as business expenses and reclaim VAT. These small, undetected errors add up, and the tax waste alone can exceed what you are paying for accounting.
Half of your team is chasing errors
Your Shopify store sells items that you no longer have. Your fulfillment center stores items that are not available on your Shopify store. You could use the manpower and transaction costs reclaimed from error-fixing to boost your sales growth.
Your company's value is at risk
When it is time to sell the company, buyers will perform due diligence. If they find that you have failed to recognize revenue correctly for gift vouchers or 3-year prepaid services under accrual accounting rules, their trust evaporates, and the deal you have worked towards could fall apart.
Your financial data is insecure
While you invest heavily in your platform’s security, is your accountant hosting all your critical financial data on an old, vulnerable server? A single ransomware email could lock you out of your records, or worse, leak all of your customer invoice data to the darknet.
Your Finance, Future-Focused and Credible
We started Brainbill to provide one of the core pillars for your SaaS business and e-commerce store growth. We start with bookkeeping, develop your financial engine for growth and follow through till the successful exit.

These e-commerce companies already hire their teams and do payroll in Lithuania (No of employees on 2025-07-15): Vinted (1467), Nord Security (1379), Wargaming (766), Hostinger (468), Wix.com (275), Oxylabs (256), Revolut (241), Orbio (239), Flo Health (226), Kilo Health (206), Omnisend (191), carVertical (161), Kayak (108), CoinGate (51), Shopify (25), etc.
The Complete Finance Stack for Online Business
Our service is more than just bookkeeping. It's a comprehensive suite of tools and expertise designed to help you scale.
Automated Sales & Payout Reconciliation
We integrate directly with Stripe, Shopify Payments, and PayPal. Your sales, refunds, and chargebacks are reconciled automatically, so you can eliminate human error and get a perfectly accurate view of your cash flow.
Global Tax Compliance
Our service includes EU VAT OSS and worldwide sales tax bookkeeping. This means we manage the complexities of cross-border tax, allowing you to sell anywhere without worrying about compliance.
Future-Focused Reporting & KPI Tracking
We provide you with ongoing cash flow monitoring and the key metrics investors want to see, like LTV and CAC. This means you move beyond historical reports, so you can make proactive decisions that directly increase your business's value.
Inventory & 3PL Synchronization
Our system ensures your stock is perfectly synced with your Shopify store and 3PL provider. This means you can prevent stockouts of sellable items and stop selling items that are no longer available, protecting your customer experience and minimizing transaction costs.
Flexible, Scalable Service
Our tech stack is built to handle businesses doing 100 or 100,000 monthly sales. This means our capacity grows with you, so you never have to worry about outgrowing your accounting firm again.
International Accounting and Tax Advisory
A single global store often runs several entities for compliance, tax and asset protection. We operate in the EU and USA, so we see the whole picture and help you grow the business, not a single entity.
Have a Question?
Here are answers to some common questions we get from founders.
Our tech-driven approach was built for this. Unlike traditional firms, our automated systems and specialized focus mean we can easily scale with you, whether you have 100 or 100,000 sales. Your growth will never be capped by our capacity.
Absolutely. We take security as seriously as you do. Our internal systems are NIS2 compliant, and we avoid most of the vulnerabilities of typical accounting setups.
No. There are no development or installation costs for you. We handle the entire setup. We aim to make the transition seamless and fast, so you can see the value in several weeks.
We specialize in the narrow niche of e-commerce and SaaS businesses. That said, our clients operate with different business models in this niche, and we have deep experience in solving various financial challenges they face. If you feel your business model exposes you to some unique challenges, please tell us more about it and we will let you know how we would solve them.
Not at all. We believe in earning your business every month. That's why we have no long-term commitments and a cancel-anytime policy.
We do all traditional accounting and tax reporting for Lithuanian companies (UAB and MB): payroll, real estate tax, corporate income tax, profit distribution, etc. We do annual IFRS returns for the US Inc and LLC entities. We rely on our partners for payrol and corporate income tax reporting in other countries.
Traditional accountants focus on historical compliance. We focus on increasing your company's future value. We provide the strategic financial insights and industry-specific metrics you need to accelerate growth, secure investment, and prepare for a successful exit.
