ERP & Accounting Systems Consulting for Growing Businesses.

Certum Solutions is an accounting and systems consulting firm for growing businesses. We provide outsourced bookkeeping and accounting, accounting software implementation (QuickBooks, Xero, Odoo, Digits, and more), ERP and inventory implementation (Cin7, Katana, MISys), Fractional CFO and business advisory, and operational systems consulting. We work with businesses generating $1M to $30M annually that have outgrown basic bookkeeping but aren't ready for enterprise ERP. We are platform-agnostic, woman-owned, BBB accredited, and have served 500+ clients nationwide.

Certum is platform-agnostic and implements whatever is best for your business. We are a certified QuickBooks Solution Provider (top 5% nationally, 7 Intuit awards), Certified Xero Bronze Partner, Odoo Official Partner, Certified Cin7 Partner, and Certified Digits Partner. We also work with Zoho Books, Katana MRP, MISys Manufacturing, and other platforms. We give you an honest recommendation based on your actual needs — not what earns us the highest referral fee.

Our pricing depends on your business size, systems, and service level. Implementation projects are fixed-scope with clear pricing delivered in a proposal after a free discovery call — no surprise fees. Ongoing bookkeeping and advisory services are priced on a monthly retainer based on transaction volume and scope. The free discovery call is the right place to start — we assess your needs and give you a clear quote, not a range that doubles by project end.

Most likely, yes. Certum has served clients across manufacturing, distribution, construction and contracting, professional services, eCommerce and retail, nonprofits, food and beverage, technology and SaaS, equipment rental, healthcare, and trades and field service. Each industry has unique accounting requirements — job costing for contractors, grant tracking for nonprofits, inventory costing for manufacturers — and we configure every implementation around those specific needs.

This is one of the most common questions we hear — and the honest answer is: it depends. Many businesses assume they need ERP when what they actually need is a properly implemented accounting system with the right integrations. ERP adds significant cost and complexity. Certum assesses your operations vendor-neutrally and tells you honestly which path makes sense. If you need ERP, we'll tell you and help you get there. If you don't, we'll protect you from an expensive decision you don't yet need.

Certum Solutions is headquartered in Monroe, NC; serving the Charlotte metro and surrounding area. We provide full remote services to businesses nationwide across all 50 states — the majority of our clients are served remotely via screen share, video, phone, and cloud accounting access. On-site work is available for businesses in the Carolinas, surrounding region, or upon request.

Most QuickBooks implementations take 2–6 weeks, depending on complexity, data migration needs, and integrations. Our fastest go-live was a full QuickBooks Enterprise implementation with inventory in 32 days. We provide a fixed timeline and discovery report in writing before any project starts.

QuickBooks is an accounting system — it manages your books, invoices, payroll, and financial reporting. An ERP (Enterprise Resource Planning system) connects accounting to your broader operations: manufacturing, inventory, purchasing, CRM, and HR in a single platform. Many businesses between $1M and $15M don't need an ERP — they need a properly implemented QuickBooks environment with the right integrations. We help you make that call honestly, without vendor bias.
